Gettin G to Know
Castro valley Boulevard
The boulevard is the heart of Castro Valley. The streetscape is designed to welcome resident and visitors alike to a main street environment. Shops, an important source of local tax generation, border the tree lined sidewalks which are wide, well planted, and furnished with seating to encourage enjoyment of the streets. Identity elements define the core of the boulevard. Public art is incorporated into the gateway markers and seating blocks that line the sidewalk.
Complete Street principles have guided the incorporation of class II bicycle lanes, enhanced crosswalks, wide sidewalks, and transit facilities which allow all types of people using all forms of mobility safe access along the street and to retail destinations.
Recognizing the importance of local creeks to the community and health of the bay environment, innovative water quality facilities are featured as part of the streetscape. At many corners, rain gardens capture and treat water in enlarged planters. The increased planting contributes to the unique character of the district while filtering out pollutants. Pavers with gravel filled joints that allow water to pass through to an underground chamber maximize on street parking for shoppers while serving to capture stormwater.
i.3 How to use tH is Plan
County Agencies
The County of Alameda will use this plan to set maintenance performance standards for the complete streetscape. Streetscapes often involve multiple jurisdictions with interrelated responsibilities. This document should define those responsibilities and guide collaboration toward a common set of goals. Specific chapters will be useful to establish a scope of work for contractor performed maintenance activities.
Maintenance Contractors
A scope of work is defined to guide contracted maintenance firms and personnel as to their responsibilities and minimum performance of duties. Additional guidance is provided as references.
Boulevard sidewalks are well lighted, wide, and tree lined to encourage walking and strolling to local serving shops.

01 Planting
1.1 overview statement
Vegetation along the boulevard requires a dedicated maintenance regiment to keep plant material healthy and groomed where appropriate. Over time, plants that are shorter lived or not thriving require replacement. This chapter describes the maintenance goals for plant health and appearance and sets specific criteria for fulfillment of these objectives. Plants require seasonal care such as deadheading and trimming. Soils require nutrients and compost to maintain their absorption and friability for supporting roots. Weeds require removal. Replacement planting is needed where species naturally die out or have proven to be less suitable. Occasional pest infestations require treatment. Sustainable objectives supporting Bay Friendly practices are included to reduce resource use and minimize or eliminate use of toxic chemicals. Maintenance personnel are also protected by adherence to these principles.
1.2

1.3 trees
Street trees are the primary framework element that defines the corridor and sidewalk environment. As they mature, their canopy will give scale to the street, calming traffic and shading pavement. Special underground soil treatments allow roots to spread while minimizing potential for sidewalk damage.
Maintenance Principles & Guidelines
1. Trees shall be main Tained in a healT hy, vigorous growing condi T ion.
1.1 Treat trees with non-toxic chemical applications to keep free from disease and concentrations of pests.
1.2 Ensure proper working order of irrigation system.
1.3 Inspect trunks and branches for damage and repair. Adjust stakes and ties if rubbing occurs.
1.4 Stake assemblies shall be checked regularly and removed as soon as the tree is able to stand upright on its own without risk of breaking. Generally, tree stakes shall be removed two to four years after planting. No stakes shall remain after four years without written approval by the County Arborist or Public Works Representative.
1.5 Before any stakes are removed, remove tree ties and allow the tree to remain without support for a period of time to observe structural stability of the tree. Remove tree stakes only when tree has been proven to be structurally stable. Any restaking shall be done with originally specified materials.
2. s elec T ive pruning prac T ices shall address immediaT e clearance needs and encourage good long T erm form.
2.1 Broken branches should be cleanly trimmed.
2.2 Correct poor branching structure such as incised bark, vertical crotches, and competing leaders.
2.3 All sucker growth from trunk and base of trees shall be removed monthly or as required up to twelve feet (12’) from the ground to maintain a clean appearance.
2.4 A vertical clearance of 168 inches is required above all parking spaces. A vertical clearance of 84 inches is required above all walkways. Shorten and ultimately remove lower branches within these areas that may conflict with pedestrian and vehicular traffic.
2.5 The cutting blades on pruning shears, clippers, blades, saws, etc. shall be sterilized after pruning each tree to minimize the possibility of spreading disease. When pruning trees known or suspected to be diseased, cutting blades shall be sterilized (with 10% bleach solution or other approved) after each cut.
Maintaining healthy street trees through stake removal, irrigation, selective pruning, and fertilization will provide lasting value to the community and businesses.
Tree planter understory provides additional color along the sidewalk.
3. Tree canopies shall be managed To promo T e long T erm visibili T y of s Torefron T s.
3.1 Remove lower tree limbs occasionally over time to encourage views to storefronts and building frontages up to 12 feet in height. Actual heights may vary by tree species and frontage condition. For example, a London Plane tree is a tall tree and can be trained higher than a Big Leaf Maple.
3.2 At no time shall trees be top pruned to lower the canopy.
3.3 Pruning to improve views to billboards and other forms of paid advertisement is not allowed unless it conforms to these guidelines.
3.4 With written approval from the County arborist, trees may be thinned using appropriate header cuts at the main branch or trunk to allow partial views through the canopy to storefronts.
3.5 While not a requirement of maintenance, it is important to note that stores are encouraged to place signage below 12 feet in height. Blade signs facing the sidewalk and pedestrians are specifically encouraged.

sH ru B s & Ground Covers
Low growing plant material provides a seasonal appearance that is at times verdant, colorful, and textured. Species are drought tolerant. Ground coverage is high to discourage weed growth and provide a uniform completeness of planting. While species may change over time, each planting zone is given a distinct theme. Some are based on appearance while others relate to a specific function. Composition and species selection is specific to the location as follows:
r ain g ardens: Where stormwater enters to the planting area, planting is “Riparian Themed” and is composed of a mixture of low spreading native flowering iris, fine textured grass like plants such as carex, and leafy flowering groundcovers that provide additional interest. Plants must be adapted to porous soils, be drought tolerant, and able to accept periodic inundation during storm events.
d ry g ardens: Wide planters without a stormwater function are themed with combinations of dry grasses (miscanthus, muhlenbergia,) and drought tolerant flowering groundcovers such as carpet roses, achillea, and lavender.
sT ree T Tree p lan T ers: Below boulevard street trees, single species flowering plants (Day Lilies) provide accent color. Side street planters have plants with colored foliage (Blue Oat Grass and Phormium tenax ‘Jack Spratt’).

Maintenance Principles & Guidelines
1. s hrubs shall be main Tained in a healT hy, vigorous growing condi T ion.
1.1 Shrubs shall be pruned monthly only as needed to remove branches that are dead, broken, extending beyond the face of curbs or sidewalks. Do not prune plants into hedges or topiary forms - allow shrubs to grow in their natural form to their mature sizes.
1.2 Shrubs shall be pruned so as to encourage a continuous planting where individual plants are not identifiable. Prune to encourage a dense, continuous planting, with natural shape and branches reaching fully to the ground.
1.3 All other shrubs shall be pruned only as required for safety, visibility, and plant health, and allowed to develop into the natural shapes expected of the plant variety. Do not shear shrubs into topiary (shapes) unless specifically instructed.
1.4 If infestation is evident, apply non-toxic insecticidal soaps and other natural treatments. If infestation persists, maintain a reasonable control with insecticides after receipt of written approval by Public Works Agency Representative.
1.5 If regular foot traffic through a planter is preventing the groundcover from reaching full coverage of the soil, contact the Public Works Agency Representative to discuss options for redirecting the foot traffic. Consider installing pavers, stepping stones, a concrete walk, a gravel path, and/or barriers to redirect pedestrians.
1.6 Do not fertilize plantings in the low areas of the swale (rain garden).
1.7 Manage leaf litter in planters to prevent excessive build up. A 0-2” layer of settled leaves is acceptable as an additional organic compost. Remove leafs from sidewalk and in gutters at bulb outs where street sweeping is less effective.
1.8 Organic fertilizer shall be 5-5-5 formulation or similar, applied per label rate for plant type. Water immediately after applying to move the fertilizer into the soil and wash the fertilizer off of plant surfaces. Fertilizers shall be organically derived to feed plants without creating offsite water quality problems.
1.9 When applying granular fertilizers to drip-irrigated areas, the fertilizer must be washed in by hand or rainfall before turning on the drip system. Running the drip system immediately after application will push the fertilizer away from the emitters, resulting in a high concentration of fertilizer at the edge of the wetted zone. This highly-concentrated fertilizer can kill or damage plants. It is recommended that granular fertilizers be applied to drip-irrigated areas only in early spring, just prior to a moderate rainfall.
2. p lan T s shall be seasonally main Tained
To enhance appearance.
2.1 Grasses such as miscanthus, muhlenbergia shall be trimmed during winter dormancy.
2.2 Dead blooms on such plants as carpet roses, day lilies, achillea, and lavender shall be trimmed off monthly during flowering periods.
3. h ealT hy soil shall be main Tained To suppor T healT hy plan T s.
3.1 Soil samples shall be taken bi-annually from three locations at a depth of 8 inches to verify nutrients, organic matter, and permeability. The test shall include recommendations for non-chemical nutrient applications such as bone meal, blood meal, fish meal, and seaweed. Recommendations by the laboratory shall modify fertilization practices.
3.2 Organic compost shall be applied to rain garden planters bi-annually. Place two inches of well composted organic material on the surface and work into the top 4-6 inches of soil. Avoid disturbing planting by avoiding the plants and root zones.
3.3 Apply mycorrhizae per manufacturer’s recommendations to all planted soil bi-annually.
3.4 Every two years, release 20 LBS of earth worms into dry and wet gardens. Select two areas measuring approximately 8’x15’ and evenly distribute 10 LBS of earthworms throughout. Choose alternative locations each year to maximize benefit in all the planting areas. Release worms during times of seasonal rainfall.
3.5 Annual application of compost tea is encouraged.
4. p lan T ings shall be selec T ively replaced To main Tain coverage.
4.1 Shrubs and groundcovers that may be shorter lived and naturally dying out shall be replaced in kind. An annual budget of two thousand dollars
($2000) shall be designated for material purchase of replacement plants. Planting shall generally occur once per year in the fall or early spring. Labor costs are considered part of the maintenance contract base services.
Select Species Name (Botanical / Common) General Replacement Schedule
Achillea / Yarrow 3-5 years
Arctostaphylos ‘Pacific Mist’ 8-10 years
Carex tumicola / Berkeley Sedge 5-8 years
Epilobium canam / CA Fuchsia 4-6 years
Helichtotrichon / Blue Oat Grass 5-8 years
Hemerocalis / Day Lily 5-10 years
Lavandula ‘Provence’ / Lavender 6-8 years
Muhlenbergia rigens / Deer Grass 8-10 years
Rosa ‘Magic Carpet’ / Rose 8-10 years
4.2 Shrubs and groundcovers that can be demonstrated to be performing poorly, subject to repeated infestations, or are no longer desired by the Public Works Agency Representative, may be replaced as directed and funded.
1.5 weedin G & tras H r emoval
Maintenance Principles & Guidelines
1. e liminaT e invasive plan T s and weeds before T hey can infes T plan T ing areas.
1.1 Noxious and invasive weeds such as Oxalis sourgrass, Dallis, Johnson, Kikuyu, Nut and Bermuda grass shall be removed immediately. At no time shall these or similarly invasive weed plants be present in the project area.
1.2 These plants may require chemical herbicide treatment to remove. Treat only spot locations using EPA and manufacturers recommended application techniques that protect workers, nearby people, and water bodies.
2. r emove weeds regularly from plan T ing areas, paving, and from under T ree graT es.
2.1 Keep basins and areas between plants free of weeds using hand and tool methods. Avoid frequent soil cultivation that destroys shallow roots. Use mulches to help prevent weed seed germination.
2.2 Non-toxic treatments such as white vinegar may be used to control weeds in cracks.
3. r emove T rash and o T her debris from plan T ing areas on a regular basis.
3.1 All trash, litter, leaves, weeds, sweepings, and trimmings shall be removed and disposed of legally offsite.
3.2 Rain gardens may require extra care to remove small trash items such as cigarette butts from places where the gutter empties into the planter.
1.6 m ulCH in G
Maintenance Principles & Guidelines
1. m ain Taining a deep layer of mulch
greaT ly reduces T he labor and maT erials needed To con T rol weeds, reduces waT er use, and helps T he plan T s s Tay healT hy.
1.1 Add additional mulch annually to ensure full coverage to a depth of 3”.
1.2 Decomposition of organic mulch is considered normal wear and tear, and replacement of decomposed mulch is required seasonally. Mulch is not required in areas where plant foliage completely covers the soil surface, such that the soil is not visible through the foliage. Any mulch found outside planter areas shall be returned to the planter on a weekly basis.
1.3 Keep tree trunks clear of mulch. Provide mulch under tree grates.
1.4 Do not place mulch in rain gardens where inundation may occur and transport mulch to drain inlets.
1.5 When replacing existing mulch, use a mulch product that is similar in appearance to that already at the site. Mulch product is identified in the appendix.

04 Stormwater management
4.1 overview statement
Treatment of stormwater is an integral component of green streets. It is an effective solution to prevent runoff from polluting local creeks that flow into San Francisco Bay. Castro Valley Boulevard has two types of water quality Best Management Practices (BMPs): rain gardens and permeable paving with detention systems. The purpose of the raingardens is to allow sediment and pollutants to settle out of the stormwater runoff and to discharge the water gradually into the sewer system and eventually into the Bay. The rain garden consists of a curb cut allowing storm water to flow from the street into planters filled with permeable soil. Water can exit the planter basin through a perforated drain pipe at a reduced rate. Permeable paving allows water to flow through open joints into a system of subterranean chambers filled with permeable soil. Street trees are planted in the same soil chamber. This modular, underground chamber system is called the “Silva Cell” system and utilizes the capacity of soil for stormwater management and healthy tree growth. A perforated drain pipe allows water to exit the chamber if needed. This chapter documents the minimum maintenance activities required to support the two BMPs implemented on Castro Valley Boulevard.
Planting and soil conditioning is described in Chapter 01 Planting. 4.2

Principles & Guidelines
1. m anage r aingardens To maximize s TormwaT er T reaT men T func T ionali T y and aes T he T ic value of T he s T ree T scape.
1.1 Before the first rain, make sure there is no trash on the sidewalk/gutter area or in the planters which can clog the rain garden drainage system. See Chapter 01 Planting.
1.2 Before the first rain, verify that all energy dissipators, such as the riprap rainwater dissipator at the Safeway driveway entrance, are in place and functional. Energy dissipator material consists of rock and gravel.
1.3 Perform a bi-annual video inspection of catch basins located in the rain gardens; flush clean-out to remove debris and blockages as necessary.
1.4 Maintain planting, replant exposed soil, and replace dead plants with new plants as described in Chapter 01 Planting. This will ensure proper biofiltration of runoff contaminants in the rain gardens.
1.5 Remove excess sediment accumulation around drains in planting area to prevent blocked drains and standing water in the raingardens. Avoid placement of bark mulch in flow areas to prevent clogging of drains.
1.6 Remove toxic or contaminated soil as needed after a spill. Remove soil to the full depth required and replace soil, planting, and irrigation in kind.
1.7 Inspect grading to ensure positive flow from the street into the center of the planter towards the overflow drain. Correct deficiencies as required.
1.8 Refer to Chapter 03 Paving for maintenance of permeable paving areas.
1.9 All stormwater maintenance practices shall be consistent with the Alameda County C.3 Stormwater Maintenance Guide, latest edition.
2. m anage s ilva c ells To maximize s TormwaT er T reaT men T func T ionali T y and aes T he T ic value To T he s T ree T scape.

This section describes the entire seatblock and district marker. Within each structure, there is integrated public art. The public art components of the street are managed by the Alameda County Arts Commission. Items include the inlayed, decorative patterns on the seatblocks and the inlayed stone panels on the vertical district markers. Ongoing maintenance will typically involve basic cleaning of surfaces. Repairs shall be carefully conducted under the joint direction of the Arts Commission and Public Works.
Arts Program Administration
The County of Alameda’s Public Art Program is managed and administered by the Office of the Alameda County Arts Commission, a division of the County of Alameda. The County’s Public Art Program was established by the Alameda County Board of Supervisors in 1994 with the enacting of Alameda County’s ”Percent for Art” ordinance (County Ordinance 94-16). The Public Art Program is based on the belief that the arts are an essential part of every successful and thriving community. The public artwork for the Castro Valley Boulevard Streetscape Improvement project adds value to the built environment and recognizes the spirit, special identity, and character of Alameda County. The artwork commissioned for the Streetscape is part of the County of Alameda’s Public Art Collection.
Excluding regular cleaning managed by PWA, the Office of the Arts Commission must be involved in the decision-making and coordination of any activities impacting or related to the public art. The Office of the Arts Commission is not responsible for the costs for cleaning, maintenance, repairs, and replacement of the public art or related elements.
