LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

PROJECT LOCATION AND SETTING Southwestern Community College District is located in southern San Diego County in California and consists of four distinct campuses located in Chula Vista, National City, Otay Mesa, and San Ysidro. The mild San Diego climate provides unique opportunities to utilize outdoor spaces for learning, events, studying, and gathering on campus. Each of the four sites is unique, they are different scales, and each has a different academic focus. The Chula Vista campus is the most substantial, and accommodates the largest number of students.

The facilities and grounds on the on each campus consist of both older and newer buildings and outdoor spaces.

NATIONAL CITY CAMPUS

CHULA VISTA CAMPUS

The Grounds Department is currently made up of just five staff who are responsible for the landscape maintenance of more than 150 acres of property across all four campuses. Grounds staff make every effort to provide an attractive appearance throughout the district facilities.

INTRODUCTION

PLAN PURPOSE AND DESCRIPTION Beginning in 2008, registered voters approved Proposition R, resulting in the passing of bonds for the District to use for construction, the modernization of existing facilities, furnishing and equipment, and the acquisition or the lease of real property. Over the next several years, this funding has supported the construction of several buildings and facilities including larger projects such as the Field House, the Math and Science Building, and the Wellness and Aquatics Complex on the Chula Vista Campus as well as the National City Building Phase II. In 2016, Proposition Z was passed in an effort to continue the progress on new classroom and infrastructure renovation projects. The Performing Arts Center and a new Student Union at the Chula Vista campus and an expansion of the Higher Education Center in San Ysidro are just a few of the projects that are currently in various phases of design and will be completed around 2022.

Working with campus students, faculty, and administration, the development of the Southwestern Campus Landscape Master Plan and Design Guidelines aims to provide a clear, unifying design for the campus outdoor spaces as new projects are developed. A shared vision for the outdoor campus experience is documented within this plan and should be integrated into the future growth of the campus.

AUTHORITY AND APPROVAL PROCESS The Governing Board of Southwestern Community College District Governing Board is made up of five elected members and one student member. The Board oversees the growth and development of the District’s campuses and ensures that these projects are in support of the students and community.

The plan includes guidelines for the four districtwide campuses which include:

Chula Vista Campus National City Campus Otay Mesa Campus San Ysidro Campus

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

CURRENT AND FUTURE PROJECTS The Operations and Construction Department currently oversees scheduled maintenance efforts as well as redevelopment projects on all four campuses.

Ongoing maintenance of both buildings and outdoor spaces are required on all campuses. Upgrades such as the integration of drought tolerant plantings, tree trimming, ADA upgrades, and upgrades to the irrigation control system also is required on each campus. In addition to these smaller projects, the 2018 Facilities Master Plan (FMP) identified several new projects in three different phases for each of the four campuses. Each of these projects is overseen by the Operations and Construction Department and includes upgrades to the landscape or new outdoor spaces to support the buildings.

OUTREACH PROCESS AND RESULTS Due to restrictions on public gathering because of the COVID-19 pandemic in 2020, all public outreach efforts for the landscape master plan and design guidelines occurred online. A traditional online survey, as well as a mapping exercise were sent to key stakeholders at Southwestern College. Feedback was provided by 158 staff, facility, student representatives, and individuals in the neighboring community from August to September. Participants in the online mapping exercise were asked to identify and describe the most memorable outdoor spaces and their favorite pastime space on campus. In addition, they were also asked how to improve recreation; relaxation and reflection; innovation and collaboration; and sustainability. The online survey identified how people traveled to campus, what kept them from spending time outside on campus, how they viewed the existing outdoor spaces, as well as a few other questions.

The following pages summarize the results for the survey as well as the mapping exercise for each of the four campuses. (Note: All comments are directly incorporated as provided and written).

Public outreach utilized an online survey and online mapping exercises.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

INTRODUCTION Campus landscape areas and plants provide a number of important benefits including: encouraging people to use outdoor spaces; reducing users’ stress; improving people’s moods; providing shade to reduce solar gain and increase the efficiency of building systems; slowing stormwater runoff; and improving air quality. Landscape areas compliment building architecture and define and frame spaces for people to gather outside. While each campus project may exhibit a unique design style, each should connect paths of travel and use areas with neighbouring campus projects to ensure smooth transitions. The campus visual aesthetics should be unified through the use of plants listed in Appendix B and products listed in Appendix A. Proposed plants and products not listed in the appendixes of this report are not encouraged, but may be used with approval from the campus project manager. This chapter describes the existing campus landscape features and provides general discussions about future landscape design and development. Consideration for universal design should be made with each product selected and space designed to exceed minimum accessibility standards to meet the needs of the greatest number of people.

CIRCULATION DESIGN EXISTING VEHICULAR CIRCULATION AND PARKING Vehicular circulation is a main concern for the Chula Vista Campus, and less of a concern for the other three campuses, although parking accommodations and transit access should be considered at all sites.

Chula Vista Campus The main Chula Vista Campus is accessed via two main entrances off Otay Lakes Road, as well as two secondary entrances from Otay Lake Road and another from East H Street. Each of these entrances provides vehicular access to the existing Perimeter Road, which currently encloses the majority of the campus buildings.

The future Ring Road identified in the Facilities Master Plan will reroute vehicular traffic further from the campus core on the south and east sides of the campus, while still connecting to parking lots and entrance roads.

San Ysidro Campus

Otay Mesa Campus

Similarly, the San Ysidro Campus consists of one building, which fronts W San Ysidro Boulevard.

Faculty and staff parking is allowed west and south of the building, with handicap spaces provided near the building entrance. Students use the parking lot across the street, accessed from San Ysidro Boulevard.

The Otay Mesa Campus fronts Gigantic Street, from which the parking lots may be accessed.

The main parking lot is west of the central campus and a smaller lot is located on the east side. A perimeter road, mainly used for fire or emergency access, connects the lots across the north side of the campus.

National City Campus The National City Campus fronts National City Boulevard, with a parking garage accessed from Roosevelt Avenue behind the main building to the west. The campus consisting of two buildings and a parking area, with landscape spaces between.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

CIRCULATION RECOMMENDATIONS VEHICULAR CIRCULATION All campus parking areas should provide priority parking for electric vehicles for three percent of the total vehicle capacity with charging plug-ins provided. All future parking lot upgrades should include electric charging station expansion capacity to prepare the campuses for future postgasoline vehicle accommodations.

Low-Impact Development (LID) best management practices (BMPs) for stormwater collection should be integrated into parking lot landscape areas without disrupting vehicular and pedestrian circulation. Refer to Chapter 4 for additional stormwater management recommendations.

Parking lots should be shaded with a minimum of one canopy tree per every six parking spaces, or with PV solar array systems. When solar arrays are used, trees should be provided at the end of parking aisles and at lot perimeters.

TRANSIT SYSTEM Each campus can be accessed via the San Diego Metropolitan Transit System. A bus stop is located in front of each campus, and a transit transfer station is located on the north side of the Chula Vista Campus.

Seating should be provided for each of the bus stops at each campus. The seating areas should designed to be as safe as possible, with good night lighting and open sight-lines surrounding it. Shade should also be provided for daytime transit users.

Additional seating should be incorporated into the San Ysidro MTS stop.

SOUTHWESTERN COLLEGE

EXISTING CONDITIONS AND DESIGN GUIDELINES

BIKE AND WHEELED CIRCULATION Bicycles, scooters, skateboards, are all low cost and sustainable transportation options for some users to access the campuses. Bike routes should be carefully coordinated with adjacent city and regional bike master plans to provide good connectivity and avoid gaps. Where wheeled traffic is located alongside pedestrian and vehicular traffic on campus, pavement providing delineation between different users should be incorporated to reduce conflicts. Wheel dismount zones, including bike, scooter, and skateboards, should also be established. Proper signage should be posted and rules should be enforced to ensure the walkways at the core of campus are safe and comfortable for everyone.

BICYCLE AND SKATEBOARD RACKS Adequate parking is essential to encourage riders. Each of the campuses currently has at least one bike rack, and the Chula Vista Campus has multiple bicycle parking areas. Additional bike and skateboard racks should be provided near campus entrances, key gathering points, and at the edges of dismount area. Racks should be placed so as not to impede pedestrian and vehicular traffic or emergency access areas. Racks should also be placed in highly visible and high use areas to discourage theft. Rack areas, similar to a bicycle parking lot should be considered in key locations. These should be large enough to accommodate multiple bicycles while not being so large as to be obtrusive, and should be of a type similar to other campus outdoor furniture. Rack areas should have a minimum separation between aisles of 48 inches to allow for one person to walk a bicycle, and the surface should be hard such as decomposed granite or concrete. Additionally, bike repair / tool stations can be located in the rack areas as amenities to encourage riders.

Chula Vista Campus

National City Campus

Otay Mesa Campus

The Chula Vista Campus core is primarily pedestrian space, with vehicular and parking areas located on the outer edges of the campus.

When the new Ring Road is developed, as indicated in the Facilities Master Plan, the existing southern and eastern portion of the existing Perimeter Road will be converted to a major pedestrian circulation route area, and vehicles and pedestrians will be further separated. The existing campus grid of pedestrian walkways and promenades across the campus are being strengthened with each new project as the campus develops. The main axis from, the Ring Walk, and key entries into campus should be enhanced with each campus project to ensure easy connections to users’ destinations. All pedestrian promenades should be universally accessible. Additional promenade enhancements should include unique tree planting for each major pedestrian walk to enhance the sense of place, and shaded sitting areas along each path to provide welcome respite.

At National City Campus, pedestrian walkways existing around and between the buildings and between the main building and the parking lot.

The site is mostly flat overall, and no additional pedestrian walkways are anticipated to be needed. As landscape improvement occur on the campus, the pedestrian sidewalks and pathways should be kept clear. Tree grates should be preserved along National City Boulevard to maintain an even and accessible surface.

The Otay Mesa Campus is mostly flat with large paved areas stretching between each building and paved connections between the parking lots and campus areas. The field and track area is separated from the main campus by the main parking lot. A clear path of travel should be created across or around the parking lot to provide safe pedestrian access to the field area as well as the new Autotech Facility. The path should make use of the shade provided by enhancing the parking lot. Any additional landscape improvements on the campus should ensure that pedestrian access to each building remains clear.

SOUTHWESTERN COLLEGE

San Ysidro Campus At the San Ysidro Campus, pedestrian circulation occurs primarily between the parking lot and the classroom building, along and across W San Ysidro Boulevard. The main focus of pedestrian improvements should be to provide an accessible route of travel from the parking lot to the building, including, if necessary, a new ramp, bridge, and stairs at the south side of the parking lot.

PAVING MATERIALS EXISTING PAVING CONDITIONS

PAVING RECOMMENDATIONS

Most of the walkable surfaces on all campuses are paved with concrete. Most driving areas are paved with asphalt. These materials are durable and provide uniform and accessible surfaces.

However, other types of paving can be integrated into the campuses for variety. Additionally, alternative paving can soften the harsh and sometimes impersonal spaces that result from the use of too much concrete or asphalt.

CONCRETE PAVING Concrete paving is used on the majority the campus for pedestrian spaces including plazas, walkways, and courtyards. All new concrete shall be per the campus standard color and texture. The thickness of the concrete should be determined by the vehicular or pedestrian loads that the space needs to accommodate. Textures and colors may be used to enhance outdoor learning areas, points of interest, seating areas, and pathways.

MOW CURBS Mow curbs should be used to separate turf and planting areas. They could also be used between differing types of mulch. Mow curbs should be flush with adjacent finished surfaces, and should be six-inches wide and eight-inches deep, made of natural grey concrete.

CONCRETE UNIT PAVERS Unit pavers can be used as an accent at patios, plazas or walkways. Concrete unit pavers can also be used as accessible permeable paving. To be considered permeable, the subbase must be properly prepared.

All unit pavers should be per campus standard color and type. The standard product selection in Appendix A provides layout options.

DECOMPOSED GRANITE PAVING Decomposed granite paving can be used in larger courtyards or plazas or as informal paths to break up a space and provide a less formal option for a paving surface. When it is unstabilized, it is a great option for a permeable surface to help meet stormwater requirements and reduce storage requirements. When stabilized with a polymer, the surface becomes impermeable, but acts as an accessible surface.

All decomposed granite paving should be contained with a black anodized metal edging or a concrete curb. Decomposed granite should be avoided within 20 feet of any entry into a building to avoid tracking in loose material.

EMERGENCY ACCESS ROUTES Emergency access routes that extend between buildings and through landscape areas that are otherwise separated from vehicular areas do not need to be constructed entirely of pavement. If these routes overlap pedestrian promenades, the chosen pavement can be used as the surfacing, provided the thickness supports emergency vehicles.

Decomposed granite is also an accessible choice to provide emergency access when it is used with a stabilizer. Permeable products that support emergency vehicles and can be filled with plants or turf may also be used, such as grass-pave. Grass-pave or decomposed granite access roads should be edged with mow-curbs.

Signs should be used to delineate the access area, rather than painted red curbs, particularly when alternative surfaces are used.

ASPHALT PAVING Asphalt paving should be used throughout campus in vehicular use areas including roads and parking lots. Asphalt surfaces should be contained with concrete curbs.

DECORATIVE/COLORED ASPHALT Decorative/ colored asphalt may be used in key locations to indicate a campus entry point or an important intersection. For example, colored asphalt can be used to draw attention to an intersection of pedestrian and vehicular movement, resulting in slower traffic. Decorative crosswalks may also be used on campus-owned property.

Color and pattens can be added to asphalt to enhance entry points.

PLANTING AND IRRIGATION EXISTING PLANTING CHARACTER Each campus within the Southwestern College District is slightly unique when it comes to the existing character of the planting.

Chula Vista Campus The Chula Vista Campus includes a variety of newer and older landscapes along with many mature canopy trees and large, open lawn areas where students, facility, and staff like to gather.

As the campus has developed, the integration of more adaptive and native plant species has been incorporate on the campus. Whereas, some of the older areas on campus still contain more tropical plantings. All buildings on campus are typically surrounded by foundation plantings.

Under story plantings are limited when they are under mature trees. A combination of rock and bark mulch are seen throughout the campus and large boulders have been incorporated into the landscape as a feature.

National City Campus The National City Campus has limited landscape and is located in a more urban setting with street trees in grates along the street frontage.

There is a small courtyard and ‘lawn’ area in the back which surrounded with native plantings and trees creating a nice balanced landscape.

Synthetic turf is used in place of live turf in the main courtyard and areas under exterior stairwells on the campus. The landscape along National City Boulevard is struggling from the challenges of exposure to the urban setting and there are planting areas that are missing plants.

San Ysidro Campus The majority of the outdoor areas on the San Ysidro Campus are taken up with parking. It is another campus that is within a very urban setting with limited opportunities for planting.

Where planting is incorporated, a mixture of older plantings and newer adaptive plants are utilized, but the mixture of plantings includes are several different species that aren’t cohesive.

Synthetic turf is used in place of real turf in the National City Campus courtyard.

PROPOSED PLANTING RECOMMENDATIONS Landscape planting areas should be incorporated into all new projects on each campus. Plants should be utilized as streetscape plantings, foundation plantings around buildings, screens, in parking lots, and in courtyards and plazas to help break up the space, and to provide visual interest and shade.

Within each campus, older areas should be evaluated to make sure all plant materials are in a healthy growing condition, that they are not causing maintenance issues, and that they are adding value to the visual aesthetics. Existing trees should be prioritized for preservation if they are in a healthy condition, and proposed projects should incorporate existing mature trees and plants where practicable.

Overall, new plants should be chosen from a unified palette to enhance the unified appearance of each campus, and all new planting shall be based on the approved planting list in the Appendix B. A balance of both evergreen and deciduous plant materials should be considered along with seasonal interest and color when selecting a project’s planting palette. The planting palette for all campuses should be a mix of native and drought tolerant, regionally appropriate shrubs, trees, and groundcover.

Palm trees at the Chula Vista Campus

In addition to considering the visual aspect, maintenance requirements and challenges should be taken into account. For example, massing of the same type of plant is preferred and plants should be grouped so they have the same water requirements to minimize maintenance. Tree leaf and flower litter and sap should be taken into consideration when trees are placed over walkways, plazas, or parking lots.

Trees with invasive roots should be avoided or placed only in locations where it is appropriate such as slopes for slopes stabilization. Plantings should be set back from walkways or buildings by at least half their mature width so as not to require trimming or pruning at the edges.

Additionally, all shrubs and groundcover material should be maintained in their natural form to avoid the need for increased maintenance.

Palm trees are suitable for use on the campuses in some areas, but should not be used in place of shade trees or where fruit drop will cause

unsightly or unsafe situations, such as over sidewalks.

Plant and human health should always be a consideration in planting design. Plants should be grouped according to shade or sun exposure and water needs. Plants that heavily attract bees should be kept away from pedestrian spaces, and invasive species should never be used. Plants on the CalIPC level A list and those recognized regionally as problematic species will not be approved for use on any of the campuses.

Trees should be placed to allow for their mature growth so they are not overhanging into buildings, and groupings of trees should allow enough space between trees to be able to maintain proper tree health and for ease of maintenance. Shrubs and ground over should also be spaced to allow for their mature growth.

Over-planting for an instant landscape effect should be avoided.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

Lawn areas are highly valued on campus, especially the Chula Vista Campus, and while they are notorious for using more water, they do serve a purpose as a place for people to sit, play games, or gather during events. A balance of shrubs and groundcover with lawn areas is desired for each campus. Lawn should be limited to areas where the turf can be used as active use or gathering places. Small areas of lawn less than 5 feet wide or 100 square feet total should be avoided. Artificial turf should be used in limited areas and only where appropriate, as discussed below.

Within each project area, planting area soil will be tested by an approved lab prior at the beginning of the project development. Prior to any planting, the soil should be treated to allow for proper planting growth and establishment, based on soil test recommendations and the Maintenance Guidelines in Appendix C. The soil tests should include percolation rates, and all planting areas should be evaluated for drainage issues. Any areas that drain at a rate of less than 2” per hour should incorporate additional drainage for planter areas and tree pits.

All planting areas should be protected by a layer of mulch and require automatic irrigation. Irrigation should be applied in zones corresponding to the planting hydrozones. Refer to the Irrigation discussion in this chapter for more information.

ARTIFICIAL TURF While the benefits of artificial turf has include low maintenance and little to no water, it isn’t always appropriate and should be used only when other solutions don’t work. Artificial turf heat up in the sun, requires occasional maintenance and cleaning, only last 10-15 years before it needs to be replaced, and is not very environmentally friendly. Therefore, it should be used where a permeable, non-erodible ground cover is needed, that isn’t large enough to support plants or irrigation. Where artificial turf is desired, its placement should be approved by the campus project manager prior to use.

BIORETENTION AREAS Bioretention areas occur throughout the landscape to help treat stormwater runoff from buildings, parking lots and other hardscape surfaces. Water retention areas should be carefully integrated into the landscape and blend with the adjacent areas. They will range in size based on the volume of water storage required.

Bark mulch should be avoided within these features as bark mulch tends to float and has the potential to clog drains or cover plant materials.

Planting, including trees and shrubs, boulders, and cobble can help create a visually pleasing basin.

EXISTING CONDITIONS AND DESIGN GUIDELINES

NATIVE PLANTINGS Native plantings should be used when possible.

It is important to consider the overall appearance of natives throughout the season. Some native plants can appear ‘dead’ during the summer months when they are dormant, and many are less formal and more wild in appearance than traditional ornamentals, especially over time.

When the right plant is used in the right location, native plants reduce water requirements, can help to reduce the need for fertilizer and pesticides, and can attract pollinators such as bees, birds, or butterflies. Perimeter plantings on the different campuses can be made up entirely of natives as a transitions between areas at various levels of development. On the other hand, it is beneficial to us a mixture of natives and adapted species in more formal settings, especially in the campus interiors.

REGIONAL APPROPRIATE PLANTINGS San Diego’s mild climate provides opportunities to incorporate plant material from regions across the world. Some of these plants require very little water and work well when paired with native plants. Regionally adapted, low water use plants provide year-round color, interest, and structure for a more formal landscape setting at times when native plants fade. Refer to the approved planting list in Appendix B for a range of options for plants adapted to the region that don’t require a large amount of water.

MULCH

BARK MULCH

ROCK MULCH

Mulch applied over the surface of exposed soil helps retain moisture and suppress weeds. It also enhances the appearance of the plantings areas throughout campus. Mulch should be incorporated into all planter areas at a minimum of 3” thick. Several different types of much including bark, decomposed granite, cobble and angular rock have been incorporated into projects on campus. Edging, either a metal edging or a concrete mow strip, should be utilized as a barrier between different types of mulch. Concrete mow curbs should be used between planting areas and turf. A 12” buffer of mulch should be applied at the base of all buildings.

Bark mulch creates a natural and casual appearance in planting beds, and can be beneficial to improve the health of the soil by adding organic materials as it decomposes. Bark mulch requires regular reapplication to remain effective. All bark mulch should be kept at least 2” away from tree trunks or the crown of shrubs.

Depending on the accompanying planting and plant layout, rock mulch can contribute to a modern or formal appearance, or can be part of a naturalistic stream or swale landscape.

Rock comes in several different forms including decompose granite, gravel and crushed rock, or cobble.

A weed barrier fabric or sheet polypropylene or polyester fabric specifically designed for weed control purposes should be used beneath all planted, rock mulched areas. Weed fabric should be resistant to ultraviolet deterioration and made of hardy material, yet still allow air, water and nutrients to pass through to the roots. Weed fabric should not be placed over the root balls of trees. Where a fabric is not used, a pre-emergent herbicide should be used.

IRRIGATION SYSTEMS Supplemental water supplied by irrigation systems is essential to keeping landscape plants alive and aesthetically pleasing in Southern California. Irrigation water must be applied and managed efficiently with weather-based, flow managed systems to ensure water is conserved and not wasted.

Each SWC campus has existing irrigation systems operated with automatic controllers.

The Chula Vista campus has multiple controllers that operate individual systems up to 128 stations, connected via WiFi to a Calsense central system with an on-site weather station.

Daily weather data is provided to each controller to adjust watering programs, and a tipping rain bucket temporarily discontinues irrigation upon significant rainfall events. Currently, a potable water distribution main extends into campus from Otay Lakes Road, and irrigation systems connect to it. Each point of connection includes a backflow prevention assembly, master valve and flow meter to serve its local area. New projects may involve alternative water supplies such as recycled water or rainwater captured in below grade cisterns for supplementing potable water supplies during short periods following significant rain events. Plans are to develop a recycled water distribution system that extends into campus from Otay Lakes Road. All new irrigation projects approved for recycled water use will connect to this system. Every new landscape project irrigation controller should be connected into the existing central irrigation system using Calsense verified communication modes and campus system components verified by campus management. All new and retrofitted system irrigation pipe, sprinkler heads, valves and

valve box covers should be colored, tagged, or otherwise marked according to water use type; those designated for potable water use and the types designated for non-potable water use.

The Otay Mesa campus has a 128-station controller that operates the existing campus systems. Future campus expansion to the east will include the addition of another controller and water supply point of connection.

A potable water source is used for irrigation at campuses other than the Chula Vista Campus.

Any new landscape improvements on the three campuses apart from the Chula Vista campus should include the upgrade and maintenance of existing irrigation, and expansion where necessary. When a new planting area is added or campus area is developed, the new irrigation system should be connected to an existing controller and campus central control system.

2

Where connection to an existing controller is not feasible, the project should include a new Calsense controller compatible with the existing control system. Each campus controller should be connected via an approved campus data communication link to a weather station for weather-based irrigation.

Irrigation zones within each campus should be configured according to plant hydrozones. Shrub areas should be irrigated with low-precipitationrate, overhead rotary stream equipment or via subsurface drip equipment with air vacuum relief and flush equipment. Drip equipment or other non-airborne water delivery methods should be used in small and narrow beds where overhead systems would overspray outside the planting areas, overhead watering would cause runoff, or cause wind-blown spray onto structures and building air intake systems. Trees, including those in lawn areas, should be irrigated via dedicated zones using bubblers and/or short radius spray heads. Lawns should be irrigated with the most efficient spray, rotary stream or stream rotor equipment that will evenly cover the turf area.

LANDSCAPE AMENITIES In order to take full advantage of the favourable climate in southern San Diego and to make comfortable and usable outdoor spaces for users, landscape areas need to be comprised of more than just planting. To create outdoor classrooms and encourage an outdoor culture, amenities such as walls, fences, and furniture should be considered comprehensively. The recommended furnishing types and sources are listed in Appendix A. Each feature included in the landscape should be drawn from the recommended list. Items not on the list may be included with permission from the campus project manager.

EXISTING LANDSCAPE AMENITIES Many of the outdoor spaces on all of the campuses are older and have outdated or run down amenities in need of repair or an update.

As new projects are developed on campus, modern, timeless amenities with durable finishes have been incorporate. Any existing amenities on campus still in good condition should be considered for re-purposing, where appropriate and feasible.

WALLS Wall may occur where sloped areas need to be retained in order to create flat areas for seating or to aid in creating universal accessibility. Short walls can also be used as seating for outdoor classrooms, gathering places, areas for students to wait for class, and at bus stops. Walls can act as buffers to create separation between spaces, to enclose a quiet area or delineate an active space.

To discourage damage on walls due to skate or bike activities, skate stoppers should be integrated into the top of any wall less than 36-inches high. Skate stoppers should be placed at 24” intervals. The preferred product is listed in Appendix A.

CAST-IN-PLACE WALLS For the creation of short walls, such as seating walls and walls that retain up to three feet of soil, cast-in-place walls are preferred. The concrete used for these walls should be either the same color or slightly contrasting to the pavement it is next to. Refer to Appendix A for the color and type of concrete to use.

DECORATIVE WALLS Landscape walls can serve as decorative features as well as functional elements.

Decorative walls can act as presentation areas for outdoor classrooms, separate quiet areas from busy thoroughfares, and serve as focal points in landscape areas. Decorative walls may be created from concrete and include aggregates and/or reveal sedimentary layers, or could be constructed from other materials, such as concrete masonry units (CMU). For approved decorative wall materials and potential design ideas, refer to Appendix A.

Image-Of good examples or campus amenities

CMU WALLS CMU walls often have a less formal appearance than a cast-in-place wall, and should be used in back of house situations. Even then, they should include some deliberate variation and blocklayout design. Refer to Appendix A for preferred block color and texture.

The type of fence preferred for use across most of the campuses is brushed steel woven wire mesh with minimum 2” openings, which provides good visibility through the fencing and a clean look.

Public-facing fences that enclose the outlying campuses and are used to restrict access after operating hours generally are composed of vertical brushed steel pickets. Secondary restricted access areas are fenced with 2” min. woven wire mesh, and outlying perimeter fences adjacent to non-public areas use chain-link.

Gates shall be selected to match the adjacent fence type. Exit hardware should be provided at egress points where required. All gates should comply with accessibility requirement.

CHAIN LINK The use of chain link fencing should be limited to athletic field and courts, and outlying campus perimeter areas where public access is limited. A black vinyl chain link is desired from an aesthetic value.

OUTDOOR SEATING Outdoor seating, including pre-manufactured furnishings, should be integrated into outdoor spaces to create and enhance outdoor classrooms, gathering and studying areas, and recreation areas by providing spaces to rest and socialize. Seating opportunities should be located at entrances into buildings, along the future Ring Walk as discussed in Chapter 3, along walkways, and in plaza spaces. Tables and benches should be mounted or embedded into concrete pads.

Chairs should remain moveable if possible. All seating on campus should take into consideration accessible spaces that are integrated into the design as well as elements of the weather. When appropriate, power and night time lighting should be incorporated near seating areas to allow for extended use. Furnishings should be selected from among the options in Appendix A. Some of these options include furnishings with recycled content or sustainable materials.

BENCHES

Flexible seating should be offered throughout each campus.

Benches selected for use on the campus should have backs. Durable materials should be utilized and may include wood, metal, or plastic.

GROUP SEATING AREA

FLEXIBLE/VARIABLE SEATING AREAS

Enough seating should be provided at designated group gathering areas to accommodate the desired number of users, and to provide enough space for distancing. Group seating areas should use a majority of one type of seating to create a unified space. These areas can also be utilized for outdoor classrooms.

Outdoor areas that can be used for a variety of purposes should integrate a variety of seating options. For example, provide unattached chairs that can be moved to be used near benches or seat-walls, or gathered around a table to expand the group capacity.

TABLES AND CHAIRS Gathering areas should be provided with tables.

For larger areas, a mix of table types and sizes should be provided. Generally, tables with detached chairs should be selected for maximum flexibility and use of space. Table with bench seating should also be considered.

LOUNGE CHAIRS Casual and informal seating areas and landscape spaces set aside for meditative or quiet use may include lounge-style chairs. These chairs should remain movable so each user can position them as they desire.

SHADE AMENITIES

WASTE AND RECYCLING CONTAINERS

BOLLARDS

In most situations, trees should be the first priority to provide shade. However, trees take time to grow and may need to be supplemented with other shade elements.

Waste and recycling receptacles should be easily found in the landscape spaces, but not obtrusively placed. They should be positioned to the side of walkways and gathering areas to not take up walking spaces.

Bollards can create a visual edge along a landscape area, and allow pedestrian and bicycle access while restricting vehicular access.

Selected bollards should be compatible with the other landscape furnishings.

Signs should be added to all bins to clarify which bins can accommodate what type of refuse.

REMOVABLE

SHADE STRUCTURES Shade structures or sails should be located to provide the most shade at seating areas, outdoor classrooms or event and gathering spaces. The form, color, shape, and size should match or blend with the adjacent architecture and may be a pre-fabricated or custom structure. PV solar panels and electronic charging stations can be incorporated into the structure, if required.

UMBRELLAS Umbrellas supported by tables can be used for shade at seating areas. Umbrella shade can supplement tree shade during the winter and before trees are mature at new project sites. Light-weight, solid aluminium umbrella panels are preferred due to their durability.

Some umbrellas may incorporate lighting and/ or PV solar panels to power electronic charging stations.

DRINKING FOUNTAINS Drinking fountains on campus should include water bottle fillers to encourage the reuse of personal bottles and discourage the use of single-use plastic bottles.

Removable bollards should be used at entrances to emergency lanes that are also pedestrian areas to allow emergency vehicles temporary access while restricting free vehicular movement at other times.

PERMANENT Permanent bollards can be used to delineate the edge of a landscape area, and for pedestrian scale lighting.

PLANTER POTS Planters can help delineate an outdoor classroom or plaza, can be focal points of small or large outdoor spaces, and can act as visual accents. Pot should not be used as the primary composition of landscape beds for an outdoor area, however.

FOUNTAINS Fountains should be restricted to limited uses, such as to access an entry point, provide white noise for a study area, or to be an example teaching tool. Fountains should use recirculating water and high-efficiency pumps, and have the capacity to accommodate stormwater overflows.

LIFESTYLE AMENITIES Lifestyle amenities are finding their way onto campuses to encourage student, faculty, and staff to stay on campus longer and to promote social interactions. Amenities such as these should be located in high visibility areas.

OUTDOOR GAMES

FIREPIT

OUTDOOR EXERCISE EQUIPMENT

Incorporating outdoor games can encourage and provide opportunities for social interaction.

Programmed amenities such as such as table tennis, bocce, or horseshoes in key gathering areas can enhance an outdoor experience and should be added to projects where it is appropriate. In addition, larger lawn areas can be used for freeplay and impromptu pick up games.

Providing a fire pit with seating can encourage users to linger outside and interact socially in the evening. Appropriate areas for fire pits may be at eating areas and event spaces.

Outdoor exercise equipment in combination with a designated pedestrian path can provide easy access for students and staff to a physical outlet when they have short beaks during the day. Equipment such as this can not only provide a physical outlet, but can also reduce stress, improve moods, increase self-esteem, and provide a connection to nature.

TECHNOLOGICAL CONNECTIVITY With the advancements of technology and the regular use of smart phones, there is a need to provide basic support anywhere someone might occupy a space, including the outdoors. When feasible, power and WiFi connectivity should be incorporated into outdoor spaces. Access to these types of tools will encourage students, staff, and facility to stay on campus longer and also support students who may not have access to these types of features at home.

FOOD VENDOR ACCOMMODATIONS To provide additional eating opportunities, each campus should identify areas that food vendors could be able to sell food. Spaces for food trucks should be located in prominent areas that do not imped the flow of pedestrian and vehicular traffic.

These types of features should integrate outdoor seating, power, trash and recycle receptacles, and shade to encourage people to stay.

STRATEGY Pavement and strategic brush thinning can provide necessary buffers between occupied buildings and undeveloped areas.

REQUIREMENTS Any thinning of native vegetation areas should comply with the County of San Diego Brush Management Guidelines.

REVEGETATION ADJACENT TO NATIVE VEGETATION Where planting areas exist next to native vegetation, plants selected for use should be non-invasive. Weeds should be limited through the use of mulch and the planting of appropriate vegetation to reduce volunteers.

STRATEGIES FOR BEST MANAGEMENT PRACTICES (BMPS) AND LOW IMPACT DESIGN (LID) Projects on SWC campuses must comply with local (City of Chula Vista, National City, and City of San Diego) Low-Impact-Development (LID) and Best Management Practices (BMP) requirements under California state’s MS4 regulations for stormwater management, which require the control and cleaning stormwater runoff to reduce pollution and surge events in local waterways. Most projects on the SWC campuses will likely be MS4 Priority Development Projects (PDPs), meaning they will be required to capture and control a certain percentage of runoff within the project site boundaries.

DESIGN RECOMMENDATIONS Stormwater catch and filtration facilities can be landscape features, rather than just utilitarian fixtures. Integrating stormwater basins into parking islands, former lawn areas, and other campus landscape planting areas can accommodate necessary stormwater capacity while providing interesting and varied plants for users to view and learn from.

DEMONSTRATE (EDUCATIONAL TOOLS) Stormwater management practices can be used as teaching tools for multiple disciplines; therefore, the use of signs and locating outdoor classrooms to highlight the stormwater management strategies as educational features is encouraged.

LIGHTING AND SAFETY EXISTING CONDITIONS

CAMPUS PEDESTRIAN LIGHTING

LANDSCAPE AND FEATURE LIGHTING

Lighting though out the various campuses is used for both safety and security, but also to enhance the visual experience of the campus at night. Currently all campuses include a variety of different fixtures from bollards, pedestrian scale pole lighting and lighting in parking lots. Newer projects have incorporated LED technology, dimmable lighting, and motion-sensing technology.

Pedestrian lighting should be established along walkways, ramps, stairs, entrances, plazas and courtyards. Pedestrian lighting may include bollards, pole lighting or lighting that gets integrated into a wall or stair system. Lighting levels along pedestrian pathways should be a minimum of 0.5 foot candle (f).

Special elements in the landscape should be illuminated at night with feature lighting. Inground lighting should be avoided maintenance issues and vandalism. However, up lights on specimen trees, artwork, or other unique site elements in the landscape should be used to highlight these features. All campus signage shall be well lit so they are legible in the evenings.

GENERAL GUIDELINES It is important to establish even and consistent coverage throughout all outdoor spaces. All older fixtures should be replaced with more efficient lighting systems as projects are implemented. All lighting fixture locations should be coordinated with both existing and proposed trees and their mature canopy size to avoid shading conflicts.

Contrasting hot and dark zones also should be avoided. All fixtures should include cut-off louvres to direct light downward and reduce glare and light pollution. Lighting levels should be sufficient to meet safety and security and should meet all California Title 24 code standards.

PEDESTRIAN POLE LIGHT Pole lights should be used along walkways to establish circulation paths. Pole spacing will depend on pole height, desired foot candle, and the type of light.

BOLLARDS Bollards should be concrete and should be used in smaller, intimate pedestrian gathering spaces.

Spacing will also be dependant on desired foot candle and specifically selected fixtures, but is anticipated to be closer together than pole lighting.

STREET AND PARKING LOT LIGHTING Lighting levels in all parking lots and on street should be a minimum of 1.0 foot candle (f). All fixtures shall be shielded to reduce overspill of light and provide enough light for safety and security on the street and in the parking lots. The same fixture should be used throughout all main and outlying campus parking lots to maintain continuity.

SERVICE AND UTILITY LIGHTING Lighting levels in all service and utility yards should be a minimum of 1.0 foot candle (f) and adequate levels for repair and maintenance during possible emergency situations in the evening hours.

EMERGENCY CALL STATIONS Emergency call stations are located throughout the campus. The security stations should be space so that, at a minimum, one is visible at all times from anywhere on campus. They can be mounted on a wall or installed as a standalone tower. The same style emergency call stations should be used for all campuses to be easily identifiable by all users.

Sculpture at the Veterans’ Resource Center.

MEMORIALS Memorials can be found throughout the campuses from site finishings, to pavers, to plant materials, to sculpture. Each of these memorials should be protected. As new developments occur, accommodations should be made to integrate them into the design or to relocate them to another area on campus as required.

The Chula Vista Campus includes a veterans plaza which is currently located outside the Veterans’ Resource Center. The plaza will be relocated with the development of the new Student Union, once complete.

The San Ysidro Campus has a unique feature of a memorial dedicated to a tragic event that occurred on the site prior to the building being used as a campus.

ALTERNATE LEARNING ENVIRONMENTS Students benefit in a myriad of ways when connected to nature while in learning. A natural connection helps students boost their attention, reduce stress, and improve creativity. Additionally, outdoor spaces with good air circulation provide healthier spaces for groups of people to gather. The relatively mild climate in southern San Diego County is, for most of the year, generally conducive to spending time outside. Beyond this, the COVID-19 pandemic has forced universities to consider outdoor classrooms as an alternative to teaching in a group setting while still maintaining fresh air flow and social distancing.

For all of these reasons, outdoor learning spaces should be provided at each campus. There is no single way to create these learning spaces. Some may be large enough for dozens of people while others may accommodate a small seminar or informal study group of less than 10 people. In order to be functional as a classroom outside, each alternative learning space should include:

Flexible seating to accommodate a range of total number of people.

Shaded spaces.

Options for social distancing.

Presentation space oriented so that students are not looking into the sun, and either a permanently mounted white board or a flat area for a mobile board.

Power supply and internet connectivity for students and teachers Universal access and easy connectivity to nearby buildings and equipment storage Buffers from active recreation areas, parking, walkways, and event spaces.

93

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

Additional learning opportunities can be enhanced across the campus landscapes by showcasing sustainable landscape features, such as, but not limited to, stormwater management strategies, native plants, food production plants, and sustainability sourced materials.

Refer to Chapter 4 for additional information about sustainable landscapes. In addition, plant material on campus could help support specific courses such as plant identification.

By providing interpretive signage, integrating seating or gathering areas near these features, and including sustainable landscape features into outdoor classrooms, classes across multiple disciplines can integrate these real-world examples into lesson plans in memorable ways.

Further, outdoor classrooms, while not in use during class time, can double as outdoor amenities—seating areas, gathering spots, event spaces, study rooms—for students and other campus users.

An outdoor classroom can also function as an event space or study room.

DISTRICT-WIDE LANDSCAPE MASTER PLAN It is critical for the District to have a clear direction moving into the future as each of its campuses develop. This will create a cohesive setting at each of the four campuses to help support learning. Proposed improvements and projects can be found in this chapter for the Chula Vista Campus, the National City Campus , the Otay Mesa Campus, and the San Ysidro Campus. The proposed improvements and projects within this chapter support what is currently outlined in the 2018 Facilities Master Plan including new and existing facilities, improvements to the landscape, irrigation and all outdoor spaces. The Facilities Master Plan should also be considered when developing new projects on campus.

Outdoor spaces on a campus can enrich the educational experience.

LANDSCAPE MASTER PLAN- CHULA VISTA CAMPUS LANDSCAPE CHARACTER The Chula Vista Campus is characterized by large, mature trees and expansive lawn.

Students, facility and staff have identified these trees and lawn areas as features that make the campus unique. As the campus is developed with new or upgraded buildings, there are opportunities to evolve the landscape while at the same time preserving the existing landscape features and enhancing the landscape character of the campus.

To that end, existing mature trees on campus should be surveyed and evaluated for health, maintenance, and safety concerns. Every new project should prioritize the preservation of healthy trees with no excessive maintenance issues, particularly those in the center of the campus. New projects should adapt irrigation and planting schemes to ensure no undue stress to the mature trees. Lawn areas may be preserved for active use and gathering places; however, the campus should expect to reduce the overall lawn area in favor of shrub and ground cover beds. New projects should in general prioritize low water use and native vegetation, and should aim to create a mix of shaded and sunny usable outdoor areas.

As the campus evolves, all projects should enhance the usability, memorability, accessibility, and sustainability of the campus. Stormwater management, reduction of reflected heat, outdoor learning opportunities, places for individual activities as well as group activities, and seating areas near food vendors are some of the program elements and landscape uses that should be considered and integrated into each campus project. Campus projects should also accommodate technology and connectivity, such as charging ports and WiFi hotspots.

Older buildings with mature trees and lawn areas define the central areas of the Chula Vista Campus.

STREETSCAPE AREAS ENTRY LANDSCAPES Entry areas should provide clear campus identity and safe pedestrian, bicycle, and vehicular access. Wayfinding signs should be prominently placed at entrances to help users find parking areas, bicycle racks, and campus destinations.

ACCESS ROAD LANDSCAPES Access roads should provided clear vehicular wayfinding as well as safe pedestrian and bicycle areas that allow easy connections between parking areas and campus destinations. Access roads should accommodate pedestrian and bicycle traffic as well as vehicle access, and should be lined with shade trees. Each access road should support a unique tree species.

PROMENADES/MAIN WALKS Promenades and main walkways across campus should be wide enough to provide sight-lines across campus, and delineated with trees selected to emphasize each axis. Seating areas should be located along each promenade.

Wayfinding signs should be located regularly along each main walkway.

The entry road onto campus off Otay Lakes Road is defined by Jacaranda trees and could be enhanced by integrating bike facilities.

WHEEL DISMOUNT ZONE

Pole mounted signage would need to be incorporated at key locations and entrances into the campus core. Signage would need to be paired with bike and skateboard racks and corrals to encourage people to safely lock up their devices. Additional amenities, such as a bike tool station would help to encourage people to store their bikes and board in the designated areas and encourage ridership.

Bike corral on a college campus

All wheeled transportation should be encouraged to utilize the Ring Road and Ring Walk which circles the core of campus and are described later in this chapter. In addition, all bike racks within the core of campus would need to be relocated outside the wheel dismount zone for users to access and further enforce this policy.

CAMPUS CORE/ ACADEMIC AREAS

ATHLETIC FIELDS AND RECREATION AREAS

The campus core and academic areas of the campus should capitalize on the favorable climate and optimize outdoor use. Landscape areas should encourage users to remain on campus in shaded, comfortable sitting areas, activated gathering spaces, safe walking paths, and usable learning environments.

Athletic fields and recreation areas are currently located near the outer campus areas, away from the campus core, with few obvious pedestrian connections or wayfinding markers directing campus users to them. Campus wayfinding should include athletic areas to direct users and potential spectators to these areas, and campus walkways should provide access across the vehicular and parking areas to the fields and viewing areas.

The campus core should have a unified planting and outdoor furnishing palette.

Wayfinding should be simple, with clearly delineated promenades and clear directional signs. Pedestrian areas should be universally accessible.

ACCESSIBILITY IMPROVEMENTS With a goal of Universal Accessibility, new pedestrian promenades, building access points, plazas and gathering space, and outdoor learning areas should be designed to be fully accessible.

Ramps with handrails and landings should be provided where necessary, however, flatter walkways are preferable to eliminate the need for handrails.

3

Athletic fields outside Devore Stadium and the Wellness and Athletics Center have few seating areas for spectators and rest areas for players.

Shaded seating areas should be provided at logical locations for spectators, and connected to the campus core via walkways.

UNDEVELOPED/ TRANSITIONAL AREAS Trees and shrubs should be used to provide a vegetated buffer at the campus edges where the perimeter abuts the surrounding neighborhood.

A native plant palette should be used to stabilize slope areas.

Existing walkways, paved areas, and building entries should be assessed for ease of access and accessibility compliance, and upgraded if not in compliance. The campus is large enough to accommodate ramps where they might be needed. Ramps and other improvements necessary to bring all areas into compliance should be integrated into the campus landscape.

Graded areas should be planted and mulched, and irrigation upgraded to maintain proper coverage.

PROJECTS UNDER CONSTRUCTION LANDSCAPE + NURSERY TECHNOLOGY (LNT)

FACILITIES, OPERATIONS, MAINTENANCE +GROUNDS

PERFORMING ARTS + CULTURAL CENTER (PACC)

The South Bay Botanic Garden at Southwestern College’s Landscape and Nursery Technology (LTN) is the epicentre of teaching and learning about the region’s landscapes. The 3.76-acre site supports students in the fields of Horticulture, Landscape Architecture, Landscape Trades, Sustainable Landscape Practices, Floral Design, Gulf and Turf Sports (design and maintenance), and other Nursery Occupations. The Botanic Garden and the LNT classroom buildings include a net-zero Learning Technology Center, greenhouses, and maintenance buildings that provide teaching spaces, outdoor classrooms and laboratories, community gardens, nursery display and sales areas, and event spaces. These areas include universal access, reinforce the teaching and learning opportunities, both indoor and outdoor, and provide educational opportunities to highlight sustainable design.

The project currently under construction is located on approximately 5.75 acres at the southern edge of Southwestern College main campus in Chula Vista, CA. The project replaces older, temporary buildings with a new compound consisting of five buildings well as large truck loading docks and vehicle parking. Because it sits at the edge of campus, perimeter landscaping for the project includes native chaparral plants with temporary plant establishment irrigation supplied primarily from a rainwater catch basin.

The new, Performing Arts and Cultural Center (PACC) is a multi-purpose, educational complex that will house community and public events, gatherings for cultural celebrations, as well as school activities. With 48,576 square feet of gross floor area, it contains classrooms designed for dance instruction, lecture halls, theater lab classrooms, stage prop and stage construction spaces, and two theaters for events and performances. The site and landscape will complement the adjacent Wellness and Aquatic Complex with modern pedestrian paving, seating, landscape boulders and cobble surfacing, shade and flowering trees and water wise plantings. An entry plaza at the main entrance is designed and poised for large events and an outdoor amphitheater at the south side of the building will hold smaller events.

INSTRUCTIONAL BUILDING 1 The Instructional Building 1 (IB1) will provide the first 21st century general assignment instructional space for SWC and is positioned on the campus to provide a gateway experience from the ring road into the heart of campus. This project creates a sense of arrival and intuitive wayfinding through a series of nodes along the ‘Arroyo’ that leads pedestrians through the center of the project along the north-south axis to the quad. The clusters of buildings are oriented to take advantage of daylight and wind direction for passive ventilation while creating usable outdoor courtyards that have a distinct character from the rest of the exterior landscaping. These courtyards are conceived as a series of outdoor rooms for users to gather, rest, and study either in groups or on their own. The site landscape will be a continuation of the adjacent IT Building including, modern pedestrian paving, landscape boulders and cobble surfacing, shade and flowering trees and refreshing water wise plantings.

FUTURE PROJECTS RING ROAD AND PARKING LOT IMPROVEMENTS The Ring Road development can be broken into two phases. The first phase includes the area on the north and west side of campus. This section of the road should incorporate unified planting, Ulmus parvifolia street trees, and shared bike lanes with appropriate markings until it links up to the new Ring Walk, refer to Appendix D, at the core of campus.

Phase two along the south and east sides includes the relocation of the road from the center of campus to the perimeter of campus. All pedestrian and bike traffic is removed from this section of the road and pedestrians and bikes are encouraged to utilize the Ring Walk to create a safe separation of vehicles and people.

The Ulmus parvifolia street tree should continue as the street tree in this phase as well to help define the Ring Road. Refer to Appendix D for more information on the Ring Walk.

In addition to establishing the Ring Road, all parking lots on campus should be enhanced to ensure proper vehicle shading either with canopy trees or solar arrays to reduce the heat island effect. Center islands and end aisles with planting will help mitigate the visual experience of large expanses of asphalt parking areas. Parking lots shall have a consistent planting theme and trees shall be spaced so there is one tree within 30’ of each parking space. All parking lots on campus should include end islands and opportunities at every fifth parking spot to include trees to reduce heat island effect. Planting should be integrated to help define the parking lots.

All parking lots should incorporate shade trees or PV panels to help reduce solar heat gain.

INSTRUCTIONAL COMPLEX BUILDINGS (2,3, & 4) Each of the Instructional Complex buildings on campus will help support educational opportunities in all kinds of different forms and methods. The outdoor spaces supporting these buildings should be another opportunity to facilitate learning and teaching. Because of the COVID-19 pandemic, everyone will be required to rethink how we live, how we play, how we gather, how we celebrate, and how we learn.

The ways in which we are utilizing and designing our outdoor spaces will forever change, well into the future. Educational leaders, at all levels, have worked hard to facilitate learning during this pandemic, but more adaptable spaces are needed, including outdoor spaces. The successes between functionality and design will be critical for the next few years, especially to address COVID, but also as a multi-use space, outdoor event space, flexible classroom space, respite, or even a study nook for years to come.

116

SOUTHWESTERN COLLEGE

The San Diego climate allows for outdoor activities, meetings, and gatherings on a more regular basis; however, careful considerations need to be made to address some of the challenges an outdoor setting brings. Sites will need to address the development of a space that meets social distancing guidelines and standards and accommodates flexibility for user different groups and programming from educational space to outdoor events and seminars. Spaces should consider a minimum number of students that need to be accommodated at a time for outdoor classes. A prefabricated or custom structure or shade trees will need to provide protection from the sun, inclement weather, and wind.

These types of space should include lighting, WiFi capabilities, electrical outlets, speakers and sound for the educational experience as well as seminars and events. The ability to mitigate noise from surrounding areas in a classroom setting will be important. Furniture, including tables and chairs, will need to be sturdy, flexible, stackable for storage, and practical, yet aesthetically pleasing. The proposed circulation as well as the planting and irrigation will need to tie into the existing conditions to create a seamless space that is integrated into the site.

The following renderings are just a few examples of how the outdoor spaces could be developed to facilitate flexible plazas, lawn areas, courtyards, and even shade structures to accommodate a variety of uses from outdoor classroom space, outdoor event spaces, areas for group and individual study, areas to socialize outside the classroom, areas to eat, or even areas for recreation and relaxation.

ADDITIONAL FUTURE PROJECTS There are several additional projects planned for campus which include both the modernization or improvement to existing facilities including, One-Stop Modernization, New Student Services, Track + Field Improvements, Campus Entry Landscape Improvements, and Tradewinds Cafe Landscape Improvements. While some of the projects are interior tenant improvements to the buildings and facilities, outdoor improvements should be consolidated into the projects as well.

Consideration for the outdoor areas surrounding the buildings and facilities will ensure that they are integrated into the adjacent areas of campus including all newly constructed projects.

Considerations for accessible pedestrian circulation, vehicular circulation, and emergency access should be reviewed to maintain connectivity. Outdoor amenities such as tables and chairs, benches or seating, landscape and irrigation, shade trees or structures will help to activate the spaces around these buildings.

All planting should consider the long-team maintenance goals as well as a reduction in potable water use. The approved planting palette can be found in Appendix B. Modern and sustainable site furnishings should be integrated and match the other areas of campus. Materials and furnishings, when and where appropriate, should be re-purposed. For more information on site finishings, materials and sustainability refer to Appendix A and C.

While the existing Caesar Chavez building will remain, site conditions should be modified to unite and connect this buildings with the new IT Building and Quad, the new Instructional Complexes, and the new Student Union.

LANDSCAPE MASTER PLAN – NATIONAL CITY CAMPUS LANDSCAPE CHARACTER The National City Campus has few landscape areas, and those are characterized by streetscape trees and a private courtyard that includes a large swath of artificial turf. The focus of landscape work at this campus should be to preserve healthy trees along the perimeter of the site, to replace those that are failing and to develop a resilient and memorable plant palette for the planters at the campus entrance on National City Boulevard. The courtyard area should be improved with more shade to increase usability.

STREETSCAPE AREAS ENTRY LANDSCAPES The landscape at the National City campus entry consists of a paved plaza behind raised planters supporting date palms along National City Boulevard. Some street trees in at-grade planters surrounded by tree grates also exist along the front of the campus.

Colorful and resilient shrubs should be added to the raised planters along National City Boulevard.

Additional seating could be considered at the entry plaza behind the flagpole as well. Seating should be shaded, and power sources and a WiFi hotspot should be added as well.

124

SOUTHWESTERN COLLEGE

STREET TREES

ACCESS ROAD LANDSCAPES

The street tree wells along National City Boulevard should be renovated with a refreshed topsoil and backfill blend. New trees of a more resilient species should be selected to replace the existing ornamental pear trees. Individual trees should be selected for strong central leaders, and carefully positioned in the center of the planting area. After planting, nursery stakes should be removed and temporary stakes installed to support upright growth. Existing tree grates may be reused, but should have the inner rings removed to allow for more room for tree trunk growth.

The planting area adjacent to the access ramp from the Roosevelt Avenue gate is covered with established landscape plants and should be maintained with an even level of mulch and proper irrigation coverage.

Brisbane Box street trees along Roosevelt Avenue, not planted in tree wells, should have nursery stakes removed from the existing trees.

Any new trees planted along the streets or within the campus should also have nursery stakes removed and temporary stakes installed to guide upright growth.

PEDESTRIAN CONNECTIVITY Pedestrian access and clearances should be preserved at all streets and other landscape improvements.

WHEEL DISMOUNT ZONES

CAMPUS CORE/ ACADEMIC AREAS

A wheeled dismount zone can easily be established for the National City campus to limit bikes and skateboards to the perimeter of campus outside the fenced areas of campus.

This will ensure that the pedestrian takes priority inside the core courtyards. Adequate bike parking and skateboard storage should be provided at the perimeter to encourage people to lock up their wheels and should be located in an area that is visible to discourage theft.

The existing courtyard plantings at either end of the artificial turf area should be maintained with an even level of mulch and proper irrigation coverage to enhance plant growth. More shade and additional, movable seating should be added to the courtyard to allow maximum flexibility for events, gatherings, and individual or small-group use. Additional features such as power stations and WiFi hot spot should also be included to improve the usability of the space. Lighting should be assess to ensure safe and optimal coverage for use at night. The artificial turf area should be maintained as even and universally accessible surface.

UNDEVELOPED/ TRANSITIONAL AREAS The potential for integrating planting in the corridor between the parking garage and the main building should be explored in order to reduce glare and provide shade for the main building and associated utilities.

In order to ensure that the area remains safe for pedestrians, the new landscape planters should include trees and low-growing shrubs or ground cover only, to ensure that hiding spaces are created. None should block the path of travel, which should remain universally accessible. The artificial turf area should also be maintained as even and universally accessible.

GATEWAY ENHANCEMENTS Planting renovations, in addition to identity signage will help reinforce a gateway and create cohesion across the District and at the National City Campus. The Southwestern Community College District Signage Guidelines identify a major HEC monument sign to be located on the side of the building. In addition, to this sign, a District-wide gateway monument should be created to identify each campus across the entire campuses at a more pedestrian scale. The glyph art work should related to the focus of that campus and be coordinated with the college expert on glyphs.

In addition to the gateway monument signage, the college should consider working with National city to enhance the asphalt crosswalks at National City Boulevard to further create a gateway onto the campus. This treatment could be utilize on other campuses as well.

LANDSCAPE MASTER PLAN – OTAY MESA CAMPUS LANDSCAPE CHARACTER The Otay Mesa Campus has a large expanse of open space characterized by concrete, lawn, and scattered canopy trees. Landscape improvements on this campus should focus on adding more seating and gathering areas and providing more shade.

The public-facing streetscape of the campus is the least formal area. The landscape along Gigantic Street consists of a swale and informal acacia plantings with small and randomly spaced street trees. The campus pedestrian entrance and bus stop are under-emphasized.

STREETSCAPE AREAS ENTRY LANDSCAPES Informal paths show that users cross the landscape from Gigantic Street to the pedestrian gate at the southwestern corner of the campus.

The planting area here should be formalized and replanted with resilient and non-invasive plants, and clear and logical paths of travel between the entrance and the sidewalk should be paved, preferably with permeable paving due to its proximity to the existing drainage swale. The planting beds should be mulched and maintained with colorful and non-invasive vegetation.

Seating with shade and a clear connection to the campus should be provided at the bus stop as well.

The remainder of the streetscape should be enhanced with a cohesive plant palette of primarily native plants, and the existing drainage basin between the campus buildings and Gigantic Street should be planted with a native bioswale palette. Refer to Appendix B for appropriate plant species. Ice plant, acacia, Bermuda grass, fountain and feather grasses, and other weedy plant species should be removed from this area and the entire campus.

ACCESS ROAD LANDSCAPES Planting beds adjacent to the parking lot entrances are sparsely planted, and should be revegetated with a native or low water use palette that complements the bioswale and streetscape plantings along Gigantic Street.

The access road along the north side of the buildings extends along a swath of restored native plants located between the campus and State Route 905. Weeds and non-native plants should be removed from the fence line along the access road, and native plants should be planted in available spaces. In unpaved areas that are too small for plants, weed-reducing mulch should be placed and maintained.

CAMPUS CORE/ ACADEMIC AREAS More usable spaces with flexible seating arrangements should be added to the campus core. Seating outside classrooms, places to study outside, and areas for outdoor classes should be incorporated. All of these spaces should have shade available for the majority of the seating.

Outdoor furniture should be selected from the furnishings listed in this plan to be cohesive with

the SWC image, although benches that were purchased by graduating classes as gifts to the campus should be spotlighted with strategic placement. Power sources and WiFi hotspots should be included as well. Furnishing should be placed near classroom entrances and in clusters of various sizes throughout the wide open campus areas. Seating arrangements should allow for easy circulation.

Most of the existing trees are located in circular cut-outs in the concrete. These circular planting beds should be enlarged and more shrubs should be added in order to soften the expanse of concrete while maintaining the original design of the courtyard spaces, Additional planting beds and trees should be added in order to shade the buildings and expanded seating areas as well.

PROMENADES/MAIN WALKS Promenade walkways already exist through the core of the Otay Mesa campus. However, as additional facilities are built on the eastern and western properties, additional walkways should be developed to connect pedestrians across the existing parking lots to the new learning centers.

PARKING AREAS The existing planting islands in the eastern parking lot should be enhanced with a cohesive plant palette. Planting islands with trees should added to the western parking lot to provide shade and reduce heat island effect.

Alternatively, solar arrays can be used for shade and energy production, with trees added at lot edges.

UNDEVELOPED/ TRANSITIONAL AREAS An additional drainage swale is located along the southern edge of the main parking lot. This swale should be planted with a native bioswale palette and maintained to ensure that non-native weeds don’t invade the swale and surrounding area.

Native plant use along campus edges is important at this campus because undeveloped land in Otay Mesa has a high potential to contain sensitive habitat.

OTAY MESA MASTER PLAN Several future projects have been identified for the Otay Mesa Campus to enhance and support the current programs and classes offered on campus. In addition, improvement to the outdoor spaces should be considered to provide additional shade in the courtyards as well as gateway enhancements and campus identification.

FUTURE PROJECTS FIRE SCIENCE / POLICE / EMS TRAINING FACILITIES

CLASSROOM COURTYARD ENHANCEMENTS

No formal landscaping exists surrounding the track and training area, and this area is left to seasonal vegetation only. Exposed soil and potentially weedy plants can prove problematic to adjacent stormwater basins and native vegetation. Therefore, the exposed unpaved areas outside the track should be planted with native or non-invasive ground cover to reduce erosion and weed coverage. Furthermore, additional trees and shaded gathering areas should be added to the western edge of the parking lot / eastern edge of the track and field, and at the northwestern corner of the field where landscaping can provide the benefit of shade and respite from physical exertion for users and students of the training area.

The main courtyard on the west side of the campus in the core has several opportunities for outdoor seating and gets used frequently.

However, additional shading should be incorporated into this plaza as well as coherent furnishings. There are several mismatched benches and planter pots scattered across the facade of the building. An effort to consolidate the planters and plantings will help unify the space. Were it is needed, additional furnishing should be added that match what is there currently.

An overall plan should be developed for this area to create consistency and uniformity of the space.

Planting should be incorporated where possible to reduce the amount of hardscape in this area as well.

As the Fire, Police, and EMS Training buildings are developed, the courtyard created by the complex should include shaded seating areas.

Seating areas should be equipped with power sources and WiFi hotspots as well. The training complex should be connected via landscaped walkways to the main campus as well as the track and field training area.

Site furnishings, plant materials, and planters should be coordinated within the classroom courtyards.

QUAD ENHANCEMENTS Additional outdoor space with shade is needed on the Otay Mesa Campus. A large lawn with small trees currently occupies the eastern side of the campus. It is currently a somewhat unusable space. Grass reduction should be considered and is reflected in the overall plan below and kept to the outer edges to maintain some seating areas in the grass with new canopy trees to create more shade.

Finally, larger shade shelters are incorporated into the quad to provide a flexible space for either events, outdoor classrooms, or a larger space for groups to study and collaborate on protects. Each of the seating areas should include power connections and WiFi for the users. Similar to the small niches, this area should be separated from the main path of circulation with colorful, water-wise plantings. All plant material should be provided enough room to grow within the planter area so that they do not become a maintenance issue later once everything matures.

Additional outdoor spaces that incorporate shade will provide flex spaces for events, classes, or studying.

GATEWAY ENHANCEMENTS Similar to the National City Campus, the Otay Mesa Campus lacks an identity from the street. Per the Southwestern Community College District Signage Guidelines, a Campus Monument sign should be located at Otay Mesa. In addition, Gateway Monument signs should be incorporated along the street frontage at the entries. The Gateway Monument may include glyphs relating to the areas of study on this particular campus. The design for the glyphs should be coordinated with the college expert. This will help to tie this campus together with the other campus sites and the Southwestern College District. Landscape enhancements along Gigantic Street may also be considered.

LANDSCAPE MASTER PLAN – SAN YSIDRO CAMPUS LANDSCAPE CHARACTER

STREETSCAPE AREAS

Landscape work at the San Ysidro campus should focus on enhancing the existing planting areas with a comprehensive planting plan to define the campus and create a unified identity, particularly in the planting beds at the front of the building and parking lot bordering W San Ysidro Boulevard. As the new buildings are developed, landscape areas remaining on the property should be developed to provide usable areas for students, staff, and visitors.

ENTRY LANDSCAPES The existing outdoor seating on the San Ysidro campus is limited to the two picnic tables placed near the main entrance and one bench along the western wall. The paved area in front of the main entrance, though limited in size, can be restructured to incorporate more tables and additional shade elements. Removing the curb and converting the loading zone parking space to seating should also be considered.

Seating near the main entry should include an updated an additional bicycle rack and new trash and recycling receptacles. Power charging stations and a WiFi hotspot should be included as well.

More seating is needed at the bus stop located directly in front of the building as well.

Developing a bus waiting area would provide a better connection to the neighborhood and reduce the number of people using walls, utility boxes, and the memorial as impromptu seating areas.

The existing fence around the memorial should be replaced with a less obtrusive barrier, which would shift visual the focus from the fence to the memorial itself.

The parking lot frontage planting area along W San Ysidro Boulevard should also be enhanced with a cohesive plant palette. Trees in this area would provide some shade for the future instructional building.

The furnishings for these areas should be selected from the products listed in this plan to be cohesive with the SWC image.

Additional trees should be placed on campus where space allows. If possible, trees along the southern site perimeter would provide shade for the faculty and staff parking area and some shade for the building. Shrubs in this area also can create a visual buffer between the campus site and the adjacent freeway. All planting beds should receive mulch and be maintained regularly.

As the parking structure and new instructional building are developed, the landscape space between the two should be designed as an additional outdoor seating area, with tables, benches and chairs, and shade. Power charging stations and a WiFi hotspot should be included as well.

PEDESTRIAN CONNECTIVITY An upgraded, accessible path of travel should be provided from the parking lot and future parking structure to the main building and future building.

This can take the form of a ramp along a portion of the slope between the lot and W San Ysidro Boulevard. Improved access between the two portions of the campus site would benefit all users.

SAN YSIDRO MASTER PLAN The San Ysidro Campus has two new buildings planed for future development to support the programs on this campus, a parking structure and 3-story building are to be located in the existing parking lot to the north of San Ysidro Boulevard across the street from the only other building on campus. This campus is currently very limited in outdoor spaces, so as these new buildings get developed, the adjacent outdoor spaces should be maximized as people spaces for students, facility and staff.

FUTURE PROJECTS ENTRY GATEWAY, BUS STOP, & LANDSCAPE ENHANCEMENTS The current campus lacks a front door / gateway experience. Signage, including the major monolith campus sign and the district-wide gateway monument should be incorporated into the site along San Ysidro Boulevard to help identify the campus. Planting enhancements should be made at the front of the building to be more drought-tolerant and more uniform. Proposed planting should take into consideration and be appropriate for shady conditions that are created because of the building. The bus stop located in front should also be reconfigured taking into consideration additional seating for individuals waiting for the bus. In addition, the memorial should be integrated into a new entry plan and preserved. Once it is built out, connections to the sites on both sides of the street should be considered and could be tied together with plating and signage, but may also consider a special crossing at the intersection related to the campus for additional place making and a gateway experience.

PARKING STRUCTURE/ INSTRUCTIONAL BUILDING PLAZA A new parking structure and 3-story building is proposed across the street from the existing campus building. These two structures will require an emergency access route and the Facilities Master Plan currently shows a hammerhead between these two buildings. Because of the proposed built-out character of this site, there is little room for outdoor gathering spaces, but this is a much needed amenity for this campus. The hammerhead should be designed to accommodate emergency vehicles but is also a great opportunity to develop an outdoor space for groups or individuals to gather. The shade from these buildings will make it a comfortable space to gather in the summer months during hot temperatures. Vegetation around the perimeter can help buffer the plaza from the buildings.

Removable bollards and pavers or decorative concrete paving will provide accessibly for emergency vehicles but will also create a nice hard surface for tables, chairs, and benches as allowed by the local jurisdictions and codes. Ideally, the spaces would include WiFi and electrical connections to provide opportunities for students to stay connected. The space could also be utilized for smaller events when they need to occur.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

SUSTAINABILITY STRATEGIES FOR SITE DESIGN The following guidelines for designing and maintaining a sustainable campus are based on the Sustainable Sites Initiative (SITES) certification program. SITES is a comprehensive land design and development rating system that is being used by both private and public sector projects around the world. SITES is similar to and works in conjunction with Leadership in Energy and Environmental Design (LEED) certification for building design. SITES certification is given to landscapes, site infrastructure, and outdoor spaces that demonstrate a high level of environmental and social sustainability. SITES works for all types of projects with or without a building, including parks, university campuses and commercial headquarters, as well as for new construction or major renovation of existing sites.

Like LEED, SITES is administered by Green Building Certification, Inc. (GBCI), the premier organization independently recognizing excellence in green business industry performance and practice globally. Even if Southwestern College’s campus spaces do not intend to receive certification, the SITES rating program offers achievable goals and principles for sustainable landscape development and maintenance.

Sustainable landscape development encourages the use of green infrastructure that uses or replicates natural systems to achieve a desired outcome. Green infrastructure looks to nature for advice, restores and replicates ecological systems to create human benefits, and provides strategies to prevent damage and pollution caused by construction and development. As plantings mature, the effectiveness of green practices may improve over time compared to more traditional “gray” infrastructure. Operations and maintenance requirements and costs will likely with diminish as well.

Sustainably designed outdoor spaces use less water by placing the right plant in the right place. Green infrastructure uses water where it falls, rather than sending it down the gutter, by capturing rainwater or stormwater runoff to supplement traditional irrigation. These practices save potable water and reduce water bills. Sustainable landscapes also incorporate energy-efficient equipment and lighting within the landscape to reduce the need for dependence on foreign fuel sources and to help reduce carbon emissions. They also use fewer resources by integrating materials with recycled content, durable and reclaimed materials, and regionally sourced supplies and materials.

In general, sustainably designed outdoor spaces can help improve local air quality and provide a healthier and happier environment for people by providing access to high quality landscapes, fresh air, and reduced contaminants. This optimizes health and well-being for students, faculty, staff, and visitors, as well as for the environment.

There are many benefits to sustainably designed outdoor spaces, and by integrating sustainable green infrastructure into the Southwestern College campuses, the physical campus space will become an example of leadership and enhance the desirability of SWC as a place to study and work.

This sustainability chapter is organized to guide campus landscape project planning from pre-design through construction and into long-term maintenance. By following sustainability guidelines in every step of the development of campus projects, green infrastructure will easily become an integral part of Southwestern College’s institutional operations.

SETTING SUSTAINABILITY GOALS AND GUIDELINES Each project within the campus will have different ways of achieving sustainability. Some will have more landscape than others, and some will be able to achieve higher performance goals. Yet green infrastructure and sustainable design principles can be used for all spaces with beneficial results. Several of these sustainability options are described in Chapter 2.

In order to achieve sustainability within a site, the owner and director of construction projects must support the specified goals from the outset. To this end, the performance goals and sustainability principles that the owner wishes to support and encourage within each project should be established alongside the project’s purpose, budget, physical location, and extents in the published job description. Acceptable methods of achieving the goals (e.g. roof rainwater and/or AC condensate capture) should also be clearly specified.

Establish Performance Goals and Criteria for each project At the outset of each project, the campus should establish the specific sustainability principles and performance goals the campus is willing to support. Incorporate into the published job description:

Specific site short- and long-term performance goals, including • • • • •

Measurable goals for stormwater management Water capture Potable water use reduction Incorporation of existing site features and plants Levels of recycled, sustainably sourced site material content

Acceptable methods to achieve stated goals Budget allocation

159

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

PRE-DESIGN PLANNING AND SITE CONTEXT EVALUATION. The sustainability goals and objectives cannot be achieved unless the owner and all members of the design team are aware of the baseline conditions and project objectives. The design consultants should work alongside campus representatives to assess the existing site conditions and potential methods for achieving the stated sustainability goals.

COMPREHENSIVE SITE DESIGN The relationship between the buildings and the landscape within any site is important to the achievement of sustainability goals. Additionally, the overall site layout can affect how much ambient heat is absorbed or reflected by the building and the hardscape areas. Strategic placement of vegetation that shades buildings and outdoor use areas reduces solar radiation and can substantially reduce a building’s energy consumption due to interior heating and cooling. The design and layout of materials in the landscape can affect maintenance needs inside the building as well. For example, surface materials that produce dust and particles should not be placed near building entrances without buffers. Incorporating gardens on rooftop areas has the benefit of insulating the building, retaining stormwater runoff, and providing additional spaces for planting and outdoor use.

Create a comprehensive site layout to reduce ambient heat • • •

Design outdoor hardscape to reduce indoor maintenance • •

Place deciduous trees to shade the south side of buildings in the summer, and to provide sun in the winter Place trees to shade outdoor use areas Specify light colored hardscape to reduce heat-island effects Do not place DG paths within 20 feet of building entrances.

Provide textured pavement - between DG and unpaved pathways and building entrances as a dust-reduction measure.

Allow for and plan buildings with green roofs - Assess each new project for green roof opportunities and develop where possible: • • • •

Intensive systems Extensive systems Outdoor use space on rooftops Stormwater capture systems on rooftop(s)

DESIGN FOR WATER MANAGEMENT AND WATER USE REDUCTION STORMWATER MANAGEMENT /LOW IMPACT DEVELOPMENT (LID) STRATEGIES While the civil engineer for each project will be the consultant in charge of BMP and LID requirements for stormwater basins, under the guidance of the team’s landscape architect, stormwater facilities can provide additional benefits of beyond minimal code compliance, such as soil, plant, and habitat improvements; aquifer recharge; and heat-island reduction. Natural basins have the added benefit of cleaning stormwater runoff, reducing pollutants through filtration, evapotranspiration, and phytoremediation. Benefits of reducing impermeable surfacing include capturing more stormwater and reducing runoff as well as lowering the heat island effect.

Design to capture runoff and slow the required minimum amount of runoff discharge required by local codes, plus any percentage identified in the project goals.

Use one or more the following strategies: • • • •

Natural Basins Flow-through planters Cistern structures New technology as it become available

Design to infiltrate water on site •

Maintain/improve infiltration rates across campus through the following strategies: • •

•

Reduce soil compaction Strategically locate hardscape and buildings in areas of previously compacted soil or poor infiltration rates so as to retain the areas with the best infiltration rates for planting beds and stormwater management.

Reduce the amount of impermeable surfaces throughout the site.

Use permeable pavement where possible • •

•

Use decomposed granite or other “soft” surfaces where appropriate Use pavers with base and subbase layers designed for infiltration and/or water storage.

Plan for long-term maintenance of permeable surfaces to continued ensure functionality.

Where soil and topography allow, locate runoff capture features in locations that allow infiltration.

IRRIGATION

WATER CAPTURE/REUSE

Related Sustainability Sections:

Smart water management in the landscape is a key strategy for reducing water use and preserving environmental resources. Efficient and properly designed irrigation systems also save money, reduce energy use, and lower utility costs. The use of up-to-date irrigation equipment and the application of water via a centralized control system with weather data link and flow sensing capabilities ensures minimal water waste, leakage loss, evaporation, or over watering. Careful plant selection and grouping plants by water needs or hydrozones can also reduce water use in the landscape.

Water is a limited resource in our semi-arid San Diego region. Strategic plant selection and efficient irrigation design go a long way toward reducing potable water use. Additional strategies can be implemented to both conserve water and save money on utility costs through the capture of water from unconventional sources for use in landscape areas.

SUSTAINABILITY

SOIL AND VEGETATION Healthy soils increase water infiltration, reduce runoff, store carbon, absorb pollutants, and provide a healthy rooting environment for plants.

In turn, plants with healthy roots protect the soil by reducing erosion and aiding in water infiltration. Soil management should be based on the existing soil composition and presence or absence of nutrients, organic matter, pollutants, and undesirable trace elements as discovered by the pre-design assessment. The performance goals should guide the desired percentage of site soils to be preserved, restored, and managed.

SOIL MANAGEMENT Create a soil management plan to guide soil improvement and sustainable management practices. Elements of soil management practices include:

• • • •

VEGETATION

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

MATERIALS SELECTION While vegetated areas benefit wildlife, habitat, and water, the remainder of an outdoor site can benefit people. Careful material selection and site design can result in healthier spaces for users as well as reduced construction and maintenance costs for the project’s owner. Farther reaching benefits of include the reduced use of raw materials and less pollution caused by the manufacture and transportation of products. A campus like SWC can influence the availability of responsibly produced products by specifying furniture, equipment, and site features that are created with recycled content, products that are manufactured locally, and by supporting manufacturers that are responsible with their sourcing.

One of the easiest ways to reduce the use of new materials in the landscape is to reuse existing features and materials. Paving, structures already present on a site, and existing plant material should be considered for integration into each site. Provided that the structures and materials are not hazardous, reusing 10% to 30% of existing site features provides a connection to the sense of place in addition to saving money on construction and manufacturing costs.

Additionally, ensuring that at least 30% (by cost or replacement value) of site materials, plants, and soil is sourced from regional suppliers reduces transportation cost and associated pollution, and bolsters a site’s sense of regional identity. The distance from campus that determines “regional” and “local” differs according to what type of material is being considered. Soils, compost, and mulch are likely to available from sources within 50 miles of campus, while regional boulders, rocks, and aggregate may come from as far as 100 miles from campus. Native plants are most successful if grown close to the site where they will be used, but some native or ornamental plants may only be available from growers up to 250 miles away. Local sources for furnishings, pavement, and other site materials may be up 500 miles from the site.

CONSTRUCTION PRACTICES Site construction can have as much impact on sustainability as the materials and layout of a project site itself. The campus sustainability goals and the project’s specific sustainability objectives should be communicated to the construction team from the beginning of the project. Specific guidelines for minimizing the impact of the construction process should include minimizing soil compaction and restoring soils that are disturbed, minimizing air and noise pollution, managing dust, and diverting construction and demolition materials from disposal in a landfill.

Section 4.5: Water Management

To the extent practicable, avoid disturbing existing and proposed planting areas with large vehicles during construction Restore soils in all final vegetated areas to a depth of 12 inches

Minimize air and noise pollution •

Related Sustainability Sections:

Reduce soil compaction and restore soils disturbed by construction

Identify materials that can be recycled, salvaged, or reused Separate (non-invasive) vegetation, soil, and rock material for diversion from landfill (refer to Materials Selection for reuse of materials on site, or salvage for use elsewhere) Identify partners to aid in diverting material from landfill by supporting local hauling and recycling companies with the same goals

OPERATIONS AND MAINTENANCE Long term sustainability is achieved through site maintenance and strategic operation. The design team should work closely with campus maintenance representatives throughout the design and construction process to ensure that materials and site operation strategies to meet project goals can be maintained over the long term. Each project site should be maintained per the campus Maintenance and Operation Plan found in Appendix A. However, each site also will have unique features, and should have its own specific maintenance criteria to support continued compliance with sustainability goals. A site’s criteria should also guide future disassembly and reuse strategies.

Landscape Maintenance Guidelines for SWC can be found in Appendix C. The College should work to implement site specific sustainable maintenance outlined in the plan which addresses the following:

Maintenance of stormwater treatment strategies Site specific irrigation requirements • •

Water source maintenance Watering schedules based on hydrozones, climate, and microclimate needs

Site specific soil and plant maintenance •

Fertilizers and amendments recommended application rates and schedule specific to each site’s soil composition

Material management •

• • •

Care guidelines for site specific re-used or salvaged features and materials Care guidelines for site specific furnishings and equipment Replacement guidelines for site specific furnishings and equipment Recycling guidelines for site specific furnishings and equipment

CONCLUSIONS All of the sustainability goals and features listed in this chapter can be featured as educational topic for any number of departments at Southwestern College, from Architecture to Biology, Business to Energy, Construction, and Utilities, and Landscape Nursery Technology to Construction Management.

Incorporating sustainability into the campus will position SWC as a leader by example in 21st century construction practices.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

SOUTHWESTERN COLLEGE LANDSCAPE & IRRIGATION MAINTENANCE GUIDELINES The sections below summarize routine landscape and irrigation maintenance operations helpful when managing the landscape resources at Southwestern College. These operations are intended to be cost effective and environmentally responsible while simultaneously providing a safe and inviting campus experience for students and staff alike.

PLANTING AREAS PRUNING Plant health and student and staff safety and enjoyment of the campus should help guide the landscape pruning operations. CPTED (Crime Prevention through Environmental Design) principles including providing clear sight lines, removing concealed or isolated circulation routes, and eliminating entrapment areas should be used to inform pruning operations. General pruning requirements are as follows:

TREES The scheduled pruning of trees is based on a once-a-year frequency, or as necessary due to tree damage or special needs. Trees should be pruned in accordance with the current pruning standards of the Western Chapter of the International Society of Arboriculture, the National Arborist Association, and the American National Standard for Tree Care Operations (ANSI). A certified arborist should be consulted for tree pruning operations.

Prune trees to select and develop permanent branches that have a smaller diameter than the trunk or branch to which they are attached. Remove all dead, diseased, or C-2

SOUTHWESTERN COLLEGE

damaged growth and eliminate narrow V-shaped branch forks. Reduce topping and wind damage by removing cross-over branching and by thinning out tree crowns.

Trees may also be pruned to control growth within the trees’ space limitations, to maintain the desired form, and to allow for adequate pedestrian head clearance. For safety reasons any part of a tree that may become a falling hazard should be removed. Trees in tree grates should be monitored on an annual basis to ensure the trunk of the tree is not growing into the grate. Inner rings of the grate should be removed as required.

Tree Central Leader - At no time should the central leader of any tree be pruned. All pruning cuts should be made just beyond the branch collar, lateral branches, or buds.

Flush cuts should not be allowed, nor should “stubbing” of branches.

Young Trees - Lower branches should remain in a “tipped back” or pinched condition leaving as much foliage as possible to promote caliper trunk growth. Stripping of lower branches will not be allowed. Lower branches should be cut only when the tree is able to stand without support.

Evergreen Trees - Evergreen trees (trees that are not deciduous) can be pruned or thinned at any time when necessary, although pruning during the months of September and October is advantageous to prepare the trees for the upcoming windy season. Prune trees for appearance and/or safety and remove dead or broken branches.

Deciduous Trees - It is recommended that the pruning of deciduous trees be done during the dormant season, except for blooming trees which should be pruned after blooming.

However, if a tree becomes damaged or constitutes a health or safety hazard, it may be pruned at any time, as necessary.

Palms – Palm fronds should be trimmed once they are dead and have turned completely brown; trimming green fronds can damage the palm and create a weak point for pests to enter. Trimming for most palm species is usually only necessary once or twice per year, and as necessary for palm damage and student/staff safety.

APPENDIX- CAMPUS MAINTENANCE GUIDELINES

SHRUBS

GROUNDCOVERS

The scheduled pruning of shrubs is based on a once-a-year frequency, or as necessary due to shrub damage or special needs. Shrubs should be pruned in accordance with the current pruning standards of the American National Standard for Tree Care Operations (ANSI).

The scheduled pruning of groundcover plant material is based on a once-ayear frequency, or as necessary due to groundcover damage or special needs.

Ground cover plant growth which extends onto sidewalks, curbs, valve boxes, quick couplers, or to within twelve inches of building or site walls may be pruned. “Weed Eaters” should not be used to edge ground covers unless approved by the Grounds Maintenance Supervisor.

All undesirable conditions should be eliminated per acceptable landscape maintenance practices including but not limited to plants overgrowing adjacent plants, plants encroaching onto walkways and buildings, removing spent flowers and flower spikes, and removing stray, undesirable growth. Shrubs under stress may be trimmed as necessary to reduce evaporation.

Excessive pruning or stubbing back should not be permitted. Top prune shrubs only when necessary for appearance and after interior selective branch pruning has been completed. Shrubs should be pruned and thinned using sharp, hand-held shrub pruners. Hedge shears and clippers should not be used.

Shrubs may be pruned for size and health, but generally should not be severely shaped or hedged unless it is the specific project’s design intent to create sharp lines.

Blooming shrubs should be pruned after blooming.

c

Avoid creating sharp vertical edges of plants at walkways. Where ground cover materials have old, deep growth that may extend into sidewalks, curbs, valve boxes, quick couplers, or to within twelve inches of building or site walls, thin the growth and taper the plant back a minimum of 12 inches. Replace with new plants of similar type where necessary.

Space new plants to allow for maximum growth to not overhang hardscapes.

VINES The scheduled pruning of vine plant material is based on a once-a-year frequency, or as necessary due to vine damage or special needs. Vine plant growth which extends past its allotted growing space should be pruned.

Vines should be kept tied to fences and walls using attachment methods that do not damage the vines. Blooming vines should be pruned after blooming.

C-3

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

SOIL HEALTH

FERTILIZING

For plants to thrive the soil health throughout the campus should be monitored. Maintaining the proper levels of accessible nutrients within the soil is critical for long-term landscape health.

Pre-Plant Fertilizer

Post-Plant Fertilizer: Shrubs, and Vines

Plant installation projects performed by SWC staff should apply a commercial grade flowable fertilizer that conforms to the requirements of the California Food and Agricultural Code prior to planting. No potassium chloride should be used and organic nitrogen should be from cottonseed meal and urea. Phosphorous should be from superphosphate and cottonseed meal, and potassium (potash) should be from sulfate of potash and cottonseed meal. Commercial grade fertilizer manufactured by Wil-Gro, Gro-Power, Bandini, or Kellogg (or similar) should be applied at a rate as specified by the fertilizer manufacturer and should have the following guaranteed chemical analysis:

Commercial grade fertilizer should be applied using a mechanical spreader to non-native trees, shrubs, and vines at a frequency of four times a year for non-native shrubs and vines and two times a year for non-native trees.

The frequency of fertilizer application may be modified as necessary based upon desired plant growth or soil tests that indicate nutrient deficiencies or surpluses. The commercial grade slow-release fertilizer should be in pelleted or granular form and should conform to the requirements of the California Food and Agricultural Code. It should be applied at a rate as specified by the fertilizer manufacturer and should have the following guaranteed chemical analysis:

Pre-Plant Fertilizer

Post-Plant Fertilizer: Non-native trees, shrubs and vines

SOIL TESTS Prior to plant installation projects performed

by SWC staff, and in existing planting areas experiencing plant stress or plant die out, a soils test should be performed. The soils testing should be done by an approved Agronomic Testing Company such as Wallace Laboratories (or similar), and SWC should provide the plant species intended to be planted (or already planted) in the area in question so that the laboratory can analyze the soil for nutrient deficiencies and include recommendations for how to improve the soil in their report.

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

MOWING, AERATING, AND DETHATCHING TURF AND GRASSES Turf grass should be mowed when the grass is actively growing. Cool season grasses are most active during Spring and Fall, and warm season grasses are most active during the summer months. Mowing frequency will be based upon the desired height and look of the lawn, the grass species, the soil health, and the amount of fertilization the grass receives.

Mowing operations should be scheduled frequently enough so that at most one-third of the grass leaf is removed at any one time.

Reference the UC IPM Guide to Healthy Lawns for additional information on grass species specific mowing recommendations.

Each Spring turf areas should be checked for evidence of compacted soil. If necessary, aerate the soil in the Spring when grasses are actively growing (active growing season is species dependent). Turf planted over clay soils, and turf with lots of pedestrian traffic may need to be aerated multiple times a year whereas turf planted over sandy soils can be aerated less frequently.

Dethatching should take place in mid to late Spring or early Fall when the turf is actively growing (active growing season is species dependent). Generally, it is good to dethatch turf when the thatch is greater than 1/2” thickness. Turf planted over clay soils, and turf that is watered and fertilized more than necessary often accumulates thatch more quickly, as do turf species such as bermuda grass. Tall fescues and rye grass develop thatch much more slowly. Dethatching should never take place when weeds are germinating.

MULCHING Planting bed mulching is important to overall plant health and leads to better plant growth, less irrigation evaporation, fewer weeds, moderates the soil temperature, and reduces soil compaction and erosion.

Organic Mulch (no weed barrier fabric) Planting areas should be checked twice a year to ensure a 2”-3” layer of wood mulch is maintained. A good organic mulch such as Forest Mulch by Agriservice provides a naturalistic, medium brown aesthetic that knits down and reduces erosion and evaporation loss. The organic mulch should be manufactured from tree trimmings, wood, and bark (no animal waste, sludge waste, lumber, or C&D wood by-products).

Direct contact between organic mulch and plants stems should be avoided - provide 3” clear between plant stems and the mulch.

Since organic mulch slowly breaks down

C-6

SOUTHWESTERN COLLEGE

over time adding nutrients to the soil, weed barrier fabric should not be installed beneath the mulch.

Inorganic Mulch (over weed barrier fabric) Inorganic (rock, cobble) mulch may be used in dry cobble streams, in maintenance strips adjacent to buildings, and in bio-retention basins and other locations where organic mulch would float away.

The benefits of inorganic mulches include wind resistance, fireproof material, weed suppression since inorganic mulch is installed over weed barrier fabric, and not needing to replenish the mulch as often as organic mulches. Inorganic mulches radiate heat absorbed from the sun which adversely affects plant health, so mulch locations relative to plant locations should be carefully selected.

In general, inorganic mulches that include tan/ beige/brown colors such as Mesa Cobble by Decorative Stone Solutions should be used in the landscape. Inorganic mulch should be checked twice a year to ensure rock/cobbles have not been displaced. Provide a 3” minimum layer of inorganic mulch, ensuring that the weed barrier fabric installed beneath the mulch is completely covered (not visible) once the mulch has been installed.

Direct contact between inorganic mulch and plants stems should be avoided - provide 3” clear between plant stems and the mulch. Cut weed barrier fabric to allow plant installation.

LITTER CONTROL

INTEGRATED PEST MANAGEMENT

Hand Pulling

Litter control within planting and turf areas should be considered a continuous process to help keep the campus landscape in a healthy and enjoyable condition. The regular, ongoing, monthly monitoring and removal of adverse organic litter including twigs, acorns, seed heads, etc. and miscellaneous trash litter helps keep the planting areas looking well cared for.

The United States Environmental Protection Agency defines Integrated Pest Management (IPM) an “an effective and environmentally sensitive approach to pest management that relies on a combination of commonsense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.”

Where weeds are pulled by hand they should be pulled before they reach the seed stage or exceed 4” in length. Some weed species cannot be controlled by pulling unless the entire root system, rhizomes, and stolons are removed. Weeds killed by hand pulling should be disposed of in a manner that does not transmit live weed seed or weed plant parts.

Depending upon the tree species, leaf litter may be handled on a seasonal frequency (deciduous trees, trees with flowers/seed heads/pods) or as necessary. Organic litter from trees that falls onto hardscape areas should be removed promptly for student/ staff safety; organic litter from trees that falls into planting areas and does not detract from the campus aesthetics/does not hinder understory plant health may be swept off the understory foliage and be allowed to decompose alongside the organic mulch.

SWC staff should be trained in Integrated Pest Management (IPM) principles which control pests while also minimizing the application of toxic chemicals. Plant health as well as student and staff enjoyment of the campus necessitates the controlling weeds, rodents, and other pests. Planting areas should be reviewed monthly so that deficiencies can be corrected in a timely manner and pests are not allowed to become established.

Pesticides Where weeds are killed by pesticides they should be killed before the weeds reach the seed stage or exceed 6” in length. Pesticide applications must be performed by a state licensed applicator in a manner that is safe to SWC staff and students, protects water bodies, and does not adversely affect nonweed plant growth. Do not spray pesticides when wind is present; pesticides should not contact the foliage or woody parts of plants unless required to control pests on that particular part of the plant.

Routine Weed Control The weeding of planting areas should be considered a continuous process to keep planting areas in a neat tidy condition, and to minimize competition for the non-weed landscape plants. Weeds include “any undesirable or misplaced plant” and should be killed using the following methods:

C-7

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

The following commercial grade pesticides are acceptable:

Cacodylic Acid Chlorflurecol Methyl (growth regulator) Diphenamid (pre-emergent) Diquate Fluazifop-butyl Glyphosate Isoxaben Sethoxydim Oxadiazon - 50 percent WSP (preemergent) Oryzalin (pre-emergent) Pendimethalin (pre-emergent) Trifluralin (pre-emergent) Ammonium Sulfate Magnesium Chloride Melfluidide (growth regulator) Napropamide

Growth regulating pesticides should not be applied within 6’ of shrubs, groundcovers, or vines. Growth regulating pesticides should not be applied in areas where they can infiltrate the soil and be absorbed by tree roots. Do not apply pesticides within planted stormwater basins.

C-8

SOUTHWESTERN COLLEGE

Oxadiazon should be of the emulsifiable concentration or wettable powder type, except when Oxadiazon is used under mulch.

A minimum of 100 days and a maximum of 6 months should elapse between applications of pre-emergents including Oxadiazon, Oryzalin, Diphenamid or Trifluralin.

Plants should be planted for at least 30 days and should be irrigated prior to the application of pre-emergents including Oxadiazon, Oryzalin, Diphenamid or Trifluralin.

Glyphosate may be used to kill stolon type weeds.

Ammonium sulfate and magnesium chloride should be used only in areas with Carpobrotus or Delosperma. Ammonium sulfate should not be applied in a manner that allows the pesticide to come in contact with trees, shrubs, or vines.

Post emergent pesticides may be applied every 6 months.

Pre-Emergent Herbicides - Selective and NonSelective pre-emergent herbicides may be applied to treat tree, shrub, and groundcover areas; apply per the manufacturer’s written instructions. Do not apply in seeded areas.

Post-Emergent Herbicides - Selective and Non-Selective post-emergent herbicides may be applied to treat already-germinated weeds; apply per the manufacturer’s written directions.

Routine Rodent and Pest Control Rodents and other pests should be controlled to prevent damage to irrigation facilities, damage to plants, and to promote student and staff enjoyment of the campus.

Planting Area Pest Control - Plant material in planting areas should be checked monthly (once a week minimum during periods of infestation), for rodent, fungus, and insect infestation and should be sprayed at the first sign of infestation.

Trees Pest Control - Trees should be inspected monthly (once a week minimum during periods of infestation) for rodent, fungus, and insect infestation and sprayed at the first sign of infestation. Some fungal infestations require the pruning of infected twigs and branches along with the complete disposal of pruned material off-site.

APPENDIX- CAMPUS MAINTENANCE GUIDELINES

PLANT REPLACEMENT Plant replacement should be performed as necessary to ensure a neat, well kept landscape aesthetic. SWC should maintain a hard copy and electronic records of each project’s planting plans showing the species installed, including any species changes that occurred during construction, so that replacement species are correct. Replacing plants that have died with the correct plant species ensures uniformity in the landscape and simplifies maintenance of the planting areas. Staff should ensure the irrigation system is working properly in the planting areas prior to replacing the plant(s).

Replace plants by following the planting details associated with the project’s planting plans – generally the planting pit should be two times the plant’s root ball diameter. When feasible remove all of the existing dead plant material and planting pit soil to help ensure any potential plant diseases from the dead plant are not transmitted to the new plant.

Avoid replacing native plants during the dry season.

See the Landscape & Irrigation Maintenance Schedule and Checklist.

IRRIGATION EQUIPMENT REQUIREMENTS The Grounds Maintenance Supervisor should maintain a list of all standard irrigation equipment which includes the part description, manufacturer, model number, nozzle type, radius, psi requirements, and gallons per minute. This list should be updated as necessary so that it is current with commercially available irrigation equipment, and after it is updated it should be distributed to all groundskeeping staff.

A common challenge of campus-wide irrigation systems is consistency of equipment within the system, so communicating and reiterating the importance of repairing the system using only the parts found on the standard irrigation equipment list to landscape maintenance staff is imperative.

ROUTINE MAINTENANCE Regular, ongoing, monthly monitoring of the irrigation system is important to ensure proper soil moisture conditions for optimal plant growth and health. Additionally, regular irrigation system monitoring helps reduce water waste and promote conservation.

Tree Observation Tubes The soil around trees should be probed with a soil probe, and the tree observation tubes should be checked. Tree and plant roots need to have access to a healthy balance of oxygen and moisture. When that balance is

c

skewed and the soil has too much moisture it can lead to an unhealthy, aerobic condition where plants can weaken and decline.

Standing water found in the tree observation tubes should be siphoned out as soon as it is noticed.

Overspray/Water Conservation Monthly review of each irrigation spray/rotor zone while it is in active operation will help identify if hardscape, walls, or buildings are being irrigated. Similarly, using a soil probe to review drip irrigation zones while they are in operation (or right after each zone shuts off) will help identify if enough moisture is present and if it is distributed evenly within the irrigation zone. Adjustments may need to be made to the arc, radius, flow, location and quantity of irrigation emitters, spray heads, or rotors.

Controller Programming The Groundskeeping Manager should maintain a list of all program schedules for each irrigation controller as currently programmed, including start/stop times, active days, and length of watering time for each station. At a minimum different program schedules for the wet season and the dry season should be included.

Backflow Preventer Once a year testing of the backflow preventer should be performed to ensure the backflow device is functioning properly.

C-9

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

IRRIGATION STRATEGIES It is important for landscape maintenance staff to fully understand the water requirements of different planting areas to ensure proper application of irrigation water.

Generally speaking, apply water to the soil in amounts as close to equal to that which has been depleted. In many cases around 65% of the plant root zone occurs in the top 12” of soil and this upper soil profile which receives irrigation water.

Water Conservation In accordance with state and local policies, water conservation should be practiced at all times and excessive irrigation resulting in runoff is unacceptable. The watering schedule may also need to be adjusted to prevent wind drift and over spray onto walls and paved areas.

Planting Areas Do not overwater planting areas (shrub, vines, groundcovers). Water enough to ensure moisture penetration throughout the root zone to a depth of approximately 8”-12” as verified by a soils probe. Program irrigation systems to maintain a precipitation rate of approximately 1/2” per week during the growing season and adjust the precipitation based upon observed plant health. During prolonged wet periods the irrigation sequence should be reduced or discontinued.

C-10

SOUTHWESTERN COLLEGE

Trees Tree bubbler zones should apply water with long periods in between watering events, and the soil around the bubblers should be evaluated to verify adequate moisture is present in the root zone. Trees bubbler zones in lawn areas should apply minimal water since these areas receive overhead water from lawn irrigation (supplemental - only when necessary). The amount of supplemental water should be adjusted after reviewing the tree observation tubes.

When the tubes exhibit standing water, irrigation using the bubbler system should be withheld. Sometimes capping bubblers may be necessary if overhead watering occurs in the immediate area of the tree.

Native Plants Watering requirements may vary significantly for native plants which often require less watering than non-native plants during the establishment period and once established.

Many established native plants require just one deep watering every 4 or 5 weeks during the dry season.

See the Landscape & Irrigation Maintenance Schedule and Checklist.

DRAINAGE AND MAINTENANCE OF PLANTED STORMWATER BASINS DRAINAGE Turf Areas Inspect turf areas monthly for standing water which may evidence over-watering or compaction of the soil beneath the turf, and make the necessary corrections to remedy the standing water. Inspect tree drain tubes in turf areas and remove debris, silt, grass clippings, leaves, litter, and other foreign materials. Remove any standing water found in the tree drainage tubes by siphoning and make the necessary irrigation corrections to avoid root damage.

Planting Areas (shrubs, vines, ornamental grasses, groundcovers) Inspect drainage devices in planting areas monthly including drainage sumps and tree drain tubes. Remove debris, mulch, silt, leaves, litter, and other foreign materials and thoroughly flush the system to ensure there are no blockages. Remove any standing water in tree drainage tubes by siphoning as needed to avoid root damage and make the necessary irrigation corrections to avoid root damage.

Inspect planting areas adjacent to buildings monthly to ensure positive drainage away from the building and towards inlets and drains.

APPENDIX- CAMPUS MAINTENANCE GUIDELINES

MAINTENANCE OF PLANTED STORMWATER BASINS Planted Stormwater Basins have many benefits such as increasing infiltration of stormwater into the water table, helping control and clean stormwater runoff, and providing a planted “green” amenity for students and staff.

Routine Maintenance Planting basins should be kept in good repair and the basin inlet/outlet areas should be inspected monthly for litter, debris, and silt removal. Special attention should be given to monitoring plant health in stormwater basins during wet/dry seasons because plantings located in basins may experience larger soil moisture differences during these seasons.

c

LANDSCAPE MAINTENANCE ZONES Chemicals Care should be taken when applying fertilizers, pesticides, herbicides, and other chemicals near planted stormwater basins.

Since runoff from the surrounding site often flows into these basins the plants located in stormwater basins often receive nutrients and chemicals at levels that may adversely affect plant health.

See the Landscape & Irrigation Maintenance Schedule and Checklist.

The Southwestern College District has limited resources to be able to maintain all four campuses, including limited maintenance staff. It is important to establish more manageable maintenance zones to ensure all areas on each of the four campuses are being tended to and a maintenance plan is implemented. These zones can be useful in establishing more specific schedules, establish the prioritization of different areas, and will assist the Grounds Manager in the delegation of work efforts related to ongoing maintenance or maintenance associated with a specific, immediate needs. While Otay Mesa, National City, and San Ysidro are all fairly small, the Chula Vista campus has been broken up into 14 different zones.

Repair Once a year, planting basins should be inspected for water containment including adequate drainage to and from inlet and outlet locations, inspection to ensure water ponds correctly, percolates, and outlets per the original design intent and that plantings do not obstruct flows. If the basin includes organic or inorganic mulch, ensure the mulching level is adequate. Care should be taken not to add organic mulch that can float/ clog outlet structures.

Plant basins may be temporarily modified during the wet season to prevent plant and basin damage due to excessive water. After the wet season, the basins should be repaired.

D RING WALK

LANDSCAPE MASTER PLAN AND DESIGN GUIDELINES - JULY 2021

RING WALK The new campus Ring Walk will provide a buffer between pedestrians and vehicles/parking on campus. The conversion of part of the campus Ring Road into a Ring Walk for pedestrians, bike riders and emergency vehicles will act as a newly softened front door to the rest of the campus core and new buildings. The conversion will accommodate emergency vehicle access, surveillance access, and delivery access while providing pedestrian paving and a two-way bike path. Utilities in the existing road limit the planting that can occur. Trees in pots and planted edges will enhance the traveling experience for all users and will create a inviting first impression after users park their car and make their way to the core of the campus.

The campus currently has several durable compost benches. As new projects are developed and older landscape renovated, and new furnishings introduced, these benches should be stockpiled so that they can be re-utilized along the ring walk. In addition, Jacaranda trees should be installed at the edge of the walk to further enhance the area. Areas for resting on bench with a friend or colleague or utilizing outdoor exercise equipment will create a dynamic sense of place for the campus.

The Ring Walk introduces a more pedestrian-centered core and pushes the vehicular traffic to the edges of campus.
