July 8, 2020 Board Workshop Review of Preliminary 2021 Budget (Doneux) DATE: June 30, 2020 TO: CRWD Board of Managers FROM: Mark Doneux RE: Review of Preliminary 2021 Budget ____________________________________________________________________________________ Background Each year the Board of Managers must develop a work plan for the upcoming year and establish a budget and levy to accommodate the work plan. At the May 20, 2020 Board Meeting, staff provided an update to the Board about how capital improvement project expenditures and revenue may be adjusted based on current projections. At the June 3rd Board Workshop, staff reviewed the 2020 Budget, 2020 Revised Budget, the 2021 Budget per the WMP and the 2021 Preliminary Budget based on Division Manager Recommendations. Issues The 2021 budget process will be unique in that we are both transitioning from our 2010 Watershed Management Plan (WMP) approach and budgeting to the new 2020 WMP. We also will be tracking the impacts of the COVID-19 pandemic and how it will affect our budget and revenue. The focus of the workshop will be to: 1) Review the 2021 Budget Goals, 2) Review the 2021-2023 Projected Capital Improvement Program Expenditures, and 3) Review and Comment on Preliminary 2021 Budget To support the 2021 budget process, I have updated the 2020-2021 Budget Comparison Summary that compares the current 2020 adopted budget, Revised 2020 Budget with the items identified in our new WMP for 2021 and our 2021 Budget Goals. I have also included the table that shows the 2021-2023 Projected Capital Improvement Program Expenditures. Finally, I have included a Preliminary 2021 Budget showing individual project budgets for 2021 expenditures. The Preliminary 2021 budget will be based on the items from WMP for 2021 but adjusted to reflect what programs and projects are expected to be implemented next year. At the July 22nd Board meeting, staff will provide the detailed project budgets as well as the full revenue and levy summary. Staff will review these documents with the Board at the workshop. No action is required, only general feedback is requested. Requested Action No Action Requested, Informational Only enc:

NPDES stormwater program

TBI is a regulated municipal separate storm sewer system (MS4). The District operates TBI under a State MS4 permit and an approved stormwater pollution prevention program (SWPPP) to minimize stormwater volumes and pollution to local waters. The SWPPP outlines activites for stormwater education and outreach, public involvement, illicit discharge detection and elimination, construction erosion and sediment control, post-construction stormwater mangement, and pollution prevention/good housekeeping. On an annual basis, the District evaluates its previous year SWPPP activities and accomplishments and updates its SWPPP as needed.

TBI H&H model update and expansion

In 2012, the District updated and calibrated a hydrologic/ hydraulic model of the TBI. The model determined the 2-, 10-, and 100-year flood flows for the TBI using Atlas-14 (current) precipitation depths. In addition, the model projects flood flows for the 500-year storm event which correlates to a moderate projection for the 100-year storm event in 2050. Because the model uses very coarse hydrology (over 50 acre watersheds on average) and primarily models only the hydraulics of the TBI, the District and the City of Saint Paul will increase hydrologic and hydraulic resolution to the model by adding in more detail from the tributary watersheds and municipal/MnDOT storm sewers in 2020 and 2021 (year 1 of the plan).

The Masterplan established six new zoning districts, provided the framework for the future public right-of-way and open spaces, provided guidance for private site design, and established development requirements for a Master Developer to bring the new mixed-use development to life. The City’s Masterplan encompassed approximately 135 acres including the 122-acre Ford Site property, the existing Highland Village Shopping Center property, and the CP Rail property. The Ryan Development Plan only includes redevelopment of the 122-acre Ford Site parcel and is expected to develop approximately 150,000 ft2 of Retail, 265,000 ft2 of Office, 50,000 ft2 of Civic/Institutional, and 3,800 units of residential including 1-6 unit homes, condominiums, senior housing, affordable housing, and multifamily housing. This review will cover Stormwater Management (Rule C) and Flood Control (Rule D). Permit for erosion and sediment control (Rule F) is covered under CRWD Permit 20-009. Permit for Wetland Management (Rule E) is covered under CRWD Permit 20-015. RULE C: STORMWATER MANAGEMENT Standards  Proposed discharge rates for the 2-, 10-, and 100-year events shall not exceed existing rates.  Developments and redevelopments must reduce runoff volumes in the amount equivalent to an inch of runoff from the impervious areas of the site.  Stormwater must be pretreated before discharging to infiltration areas to maintain the long-term viability of the infiltration area.

W:\07 Programs\Permitting\2020\20-013 Ford Site Stormwater Master Plan\20-013 Permit Report_R2.doc Page 2 of 6

ď&#x192;&#x2DC; Developments and redevelopments must incorporate effective non-point source pollution reduction BMPs to achieve 90% total suspended solid removal. Findings 1. A hydrograph method based on sound hydrologic theory is used to analyze runoff for the design or analysis of flows and water levels. 2. Runoff rates for the proposed activity do not exceed existing runoff rates for the 2-, 10-, and 100-year critical storm events. Stormwater leaving the project area is discharged into a well-defined receiving channel or pipe and routed to a public drainage system. 3. Stormwater runoff volume retention is not achieved onsite in the amount equivalent to the runoff generated from 1.1-inch of rainfall over the impervious surfaces of the development. a. The amount of proposed impervious is 3,755,743 ft2 (86.22 ac). b. Volume retention required: 3,755,743 ft2 x 1.1 inches x 1 ft/12 inches = 344,276 ft3 Table 1.

2. Revise XPSWMM model or plans to correspond: a. Clarify why the downstream invert between the bypass manholes and the HDS units are modeled higher than shown in the plans. This is consistently done for all HDS units included in the XPSWMM. Example: Downstream invert of Link LMH01_H01 is 804.56 in XPSWMM and 802.88 on Sheet 218 in the plans. b. Weir elevations for SFIL_BH1 and SFIL_BH2 in Multiple Link SFIL_BH are 799.5 in the XPSWMM and 799.66 (CB-05) and 799.65 (CB-06) on Sheet 224 in the plans. c. Clarify why the upstream and downstream inverts of links between StormFilters and JS Structures are modeled higher than shown in the plans. This is consistently done for all StormFilter units included in the XPSWMM. Example 1: Upstream invert of Link LSF03_JS03 is 818.18 in XPSWMM and 814.95 on Sheet 207 in the plans. Example 2: Downstream invert of Link LSF03_JS03 is 817.3526 in XPSWMM and 812.15 on Sheet 207 in the plans. d. Downstream invert of Link LSG06_JS06 is 803.2 in XPSWMM and 800.37 on Sheet 213 in the plans. 3. Provide permanently reinforced emergency overflows (EOFs) for all biofiltration basins. Dictate and plan for the EOF at the time of construction to reduce or eliminate future erosion when the basin overflows. a. Ensure 100-year HWL is below the EOF and the EOF at least 0.5’ below top of basin berm. The reinforced EOF (i.e. riprap, TRM) shall then extend to the toe of the slope to prevent erosion.

W:\07 Programs\Permitting\2020\20-013 Ford Site Stormwater Master Plan\20-013 Permit Report_R2.doc Page 5 of 6

b. Northwest basins: i. HWL = 808.1 and 808.0 ii. Proposed contours are not clearly defined, but EOF appears to be west or north side of the basins. iii. Create an EOF route with TRM to the adjacent street or public drainage system, or demonstrate that overflow velocity and shear stress will not cause erosion. c. Basin B3 i. HWL = 814.1 ii. Entire length of adjacent trail is proposed at 814.0 iii. Specify EOF location and elevation, depress trail at this location, and then reinforce slope on downstream side of trail. d. Basin B4 i. HWL = 814.0 ii. 814 contour encircles the basin. iii. Similar to B3, specify EOF location and elevation, depress trail at this location, and then reinforce slope on downstream side of trail.

June 17th, 2020 III. Permits, B. Ford Site Alternative Permitting Process Update

DATE: TO: FROM: RE:

June 11, 2020 CRWD Board of Manager Forrest Kelley, PE, Regulatory Division Manager Ford Site Alternative Permitting Process

Background Ryan Companies recently purchased the 122 acre Ford Site property in St. Paul. Permit 12-023 Ford Site Demolition was recently transferred from Ford Motor Company to Ryan, and 30% design plans were reviewed by CRWD in January. Sixty percent design drawings were submitted on January 21st, 2020. Final stormwater design plans are currently under review, and CRWD staff expect to issue Rule C. permits at the July 8th Board Meeting. Issues The scale, complexity and duration of the project necessitate a modified approach to issuing permits for stormwater management and erosion and sediment control. Coordination with City department review, approval, inspection and close out will be critical to minimize potential conflicts and duplication. CRWD staff propose the following process be used to break the 122 acre site into 10 individual permits to increase flexibility. Erosion Control: Permit 12-023 Ford Site Demolition. Transferred to Ryan on 1/17/2020 and provides for surface demolition, stockpiling of materials, and minor grading for retaining wall removal. $134,000 surety check was received from Ryan, and a surety return check was issued back to Ford for the same amount. This was based on 67 acres of land disturbance. Does not include approval for site mass grading or utility installation work. Permit closeout requested by staff 06/17/2020 Permit 20-009 Ford Site Mass Grading. Issued 05/01/2020 for mass grading of the site in preparation for utilities, right of way improvements, and building sites. Additional surety of $110,000 ($244,000 total) was submitted by Ryan Companies for the expanded land disturbance beyond the original 67 acres for plant demolition. Erosion control sureties can be returned in phases consistent with the Stormwater Management permits described in the section below. All work within permitted drainage areas must be complete for this surety to be returned.

Stormwater Management: Permits 20-013A through 20-013H. Stormwater Management permits will be broken into 8 smaller areas based on drainage boundaries to site BMPs as shown in the attached exhibit. These permits will be issued concurrently, but closeout will be phased based on completion of each area. Surety will be collected at $5,000/acre of the impervious surfaces within the public Our Mission is to protect, manage and improve the water resources of Capitol Region Watershed District.

Right of Way, Parks, and privately owned civic spaces. Surety will be returned upon completion of all Parks and ROW, and a combination of all private parcels achieving temporary stabilization, and/or gaining coverage under a new permit for which a separate surety has been collected. Permit 2X-0XX. Individual stormwater and erosion control permits for private development parcels will be applied for, reviewed, and approved following the standard permit application process. Surety will be collected at $5,000/impervious acre impervious, and returned upon confirmation of completion and BMP function. Wetland Management Permit Permit 20-015 Ford Site Redevelopment Wetlands. Approved at the 06/03/2020 Board Meeting, this permit covers wetland impacts and the required 2:1 mitigation. A surety of $37,986 will be collected as part of the financial assurances required by WCA and the City when wetland impacts are proposed to occur prior to beginning construction on wetland replacement. Surety will be returned upon completion of the required monitoring period documenting successful establishment of wetland hydrology and vegetation.

HISTORY & CONSIDERATIONS: Stormwater management installed during this phase of the project is intended to satisfy water quality requirements as part of a larger redevelopment project taking place on the property. Multiple phases of redevelopment projects have occurred in recent years at the site. Projects being accounted for with the proposed infiltration system include Phase 1, building demolition, fire lane extension, and the current 2020 project for a total new/reconstructed impervious area of 54,360 ft2.

W:\07 Programs\Permitting\2020\20-017 Hamm's Brewery improvements\20-017 Permit Report_R2.doc Page 1 of 4

RULE C: STORMWATER MANAGEMENT Standards  Proposed discharge rates for the 2-, 10-, and 100-year events shall not exceed existing rates.  Developments and redevelopments must reduce runoff volumes in the amount equivalent to an inch of runoff from the impervious areas of the site.  Stormwater must be pretreated before discharging to infiltration areas to maintain the long-term viability of the infiltration area.  Developments and redevelopments must incorporate effective non-point source pollution reduction BMPs to achieve 90% total suspended solid removal. Findings 1. A hydrograph method based on sound hydrologic theory is used to analyze runoff for the design or analysis of flows and water levels. 2. Runoff rates for the proposed activity do not exceed existing runoff rates for the 2-, 10-, and 100-year critical storm events. Stormwater leaving the project area is discharged into a well-defined receiving channel or pipe and routed to a public drainage system. 3. Stormwater runoff volume retention is achieved onsite in the amount equivalent to the runoff generated from 1.1-inch of rainfall over the impervious surfaces of the development. a. The amount of proposed impervious is 54,360 ft2. i. Phase 1 – Approximately 23,600 ft2 ii. Building Demolition – Approximately 7,000 ft2 iii. Fire Lane Extension – Approximately 7,500 ft2 iv. Current 2020 Project – Approximately 16,260 ft2 b. Volume retention required: 54,360 ft2 x 1.1 inches x 1 ft/12 inches = 4,983 ft3 Table 1.

Banking of excess volume retention of is not proposed. d. Infiltration volume and facility size has been calculated using the appropriate hydrologic soil group classification and design infiltration rate. e. The infiltration area is capable of infiltrating the required volume within 48 hours. f. Stormwater runoff is pretreated to remove solids before discharging to infiltration areas. g. Groundwater mounding is not anticipated to affect adjacent properties and buildings. 4. Alternative compliance sequencing has not been requested.

W:\07 Programs\Permitting\2020\20-017 Hamm's Brewery improvements\20-017 Permit Report_R2.doc Page 2 of 4

5. Best management practices achieve 90% total suspended solids removal from the runoff generated on an annual basis. 6. A maintenance agreement recorded with Ramsey County has not been submitted. 7. Adequate maintenance access is provided for the underground system. A sitespecific plan, schedule, and narrative for maintenance of the proposed stormwater management practices has not been submitted. RULE D: FLOOD CONTROL Standards  Compensatory storage shall be provided for fill placed within the 100-year floodplain.  All habitable buildings, roads, and parking structures on or adjacent to a project site shall comply with District freeboard requirements. Findings 1. There is no floodplain on the property according to FEMA. 2. All habitable buildings, roads, and parking structures on or adjacent to the project site comply with CRWD freeboard requirements. RULE E: WETLAND MANAGEMENT Standard  Wetlands shall not be drained, filled (wholly or in part), excavated, or have sustaining hydrology impacted such that there will be a decrease in the inherent (existing) functions and values of the wetland.  A minimum buffer of 25 feet of permanent nonimpacted vegetative ground cover abutting and surrounding a wetland is required. Findings 1. There are no known wetlands located on the property. RULE F: EROSION AND SEDIMENT CONTROL Standards  A plan shall demonstrate that appropriate erosion and sediment control measures protect downstream water bodies from the effects of a land-disturbing activity.  Erosion Control Plans must adhere to the MPCA Protecting Water Quality in Urban Areas Manual. Findings 1. Erosion and sediment control measures are consistent with best management practices, as demonstrated in the MPCA manual Protecting Water Quality in Urban Areas. 2. Adjacent properties are protected from sediment transport/deposition. 3. Wetlands, waterbodies and water conveyance systems are protected from erosion/sediment transport/deposition. 4. Total disturbed area is 1.2 acres; an NPDES permit is required. A SWPPP has been submitted. RULE G: ILLICIT DISCHARGE AND CONNECTION W:\07 Programs\Permitting\2020\20-017 Hamm's Brewery improvements\20-017 Permit Report_R2.doc Page 3 of 4

Standard  Stormwater management and utility plans shall indicate all existing and proposed connections from developed and undeveloped lands for all water that drains to the District MS4. Findings 1. New direct connections or replacement of existing connections are not proposed. 2. Prohibited discharges are not proposed. Recommendation: Approve with 3 Conditions Conditions: 1. Clarify who will be responsible for long-term maintenance of the underground infiltration system.

July 1, 2020 CRWD Board of Managers Bob Fossum, Division Manager Ford Site Funding Requestâ&#x20AC;&#x201D;MRB Crossing

Background The District has been working with Ryan Companies and the City of St. Paul on various aspects of the design of the project over the past couple of years. In April 2020, the City of St. Paul submitted a funding request for the water features and stormwater system on the Ford Site. In summary, the request included: 1. Ford Parkway Baseflow Groundwater Capture -- $200,000 2. Southern Stormwater Enhancements -- $595,000 3. Hidden Falls Regional Park Connection -- $1,500,000 (allowance) At the June 3, 2020 Board meeting, the Managers approved Ford Site funding to the City of St. Paul for elements #1--Ford Parkway Baseflow Groundwater Capture and #2--Southern Stormwater Enhancements from their 4/28/2020 funding request for an amount not to exceed $795,000. The Board further directed staff to develop a grant agreement with the City of St. Paul for subsequent Board approval. Issues During May and June, Item #3 (Hidden Falls Regional Park Connection) has been under further development and additional analysis of the feasibility and cost of this option. This option would connect the new stream feature on the Ford Site with the existing stream feature in Hidden Falls Regional Park by constructing a tunnel beneath Mississippi River Blvd. The City of St. Paul has submitted additional information and clarification on the funding request and it has been enclosed. Staff will review the funding request with the Managers. The deliverable includes detailed construction plans that the Board need not review unless interested. District Staff and City Staff will review the request with the Board. After review and discussion at the July 8th meeting, staff would intend to develop and bring a funding recommendation to the Board at the July 22nd meeting for consideration. Requested Action Review and comment only. enc:

Bob, As you may recall, in my April 28 letter requesting funding for Ford Site we identified an emerging opportunity for an enhanced water resource and public realm connection between the Ford Site and Hidden Falls Regional Park. The letter requested the CRWD Board consider a $1.5 million funding allowance for the opportunity based on a planning level cost analysis completed by Ryan Companies. The city rapidly completed a concept level feasibility study for this opportunity which included working with our development partner on a pricing exercise of the concepts. Please see the attached deliverable prepared by TKDA, dated June 30, 2020. The city’s preferred alternative is concept #2 as illustrated in the study. Phase one of the preferred alternative provides a daylighted stream and trail connection under a bridge proposed for Mississippi River Boulevard, with plazas on either side of the bridge. Phase one reflects the scope of work contemplated within the April 28 letter. The second phase of the preferred alternative provides additional trail improvements within Hidden Falls Regional Park. The total estimated (concept) cost for the entire scope studied by TKDA is approximately $2,537,900. Phase one construction is estimated to cost approximately $1,959,100. Conversations are in progress with Ryan Companies regarding phase one to clarify construction schedules, cost assumptions, and final design responsibilities. For its part the city can leverage $350,000 of anticipated infrastructure costs as a “credit” if a funding commitment is received in July from CRWD. If that occurs, phase one of the preferred alternative would reflect a total estimated (concept) cost of $1,609,100. The City respectfully requests the CRWD Board to approve funding for the full allowance requested in the letter of April 28. An affirmative in this critical decision will allow the City to rapidly complete phase one final design and remain in synch with the development program to leverage $350,000 of anticipated work as credit. The City remains vigilant for supplemental funding sources since the concept pricing exceeds what is being requested from CRWD. To that end we would re‐assess the phase one pricing package upon completion of final design and make determinations about value engineering if necessary. City staff and Ryan Companies both agree the preferred alternative is an outstanding enhancement and extremely worthwhile to pursue. We are grateful for your agency’s consideration of this significant funding request. Kindly, Wes Saunders‐Pearce Water Resource Coordinator | City of Saint Paul

Feasibility Study for Mississippi River Boulevard Crossing Between Ford Site and Hidden Falls Regional Park City of Saint Paul Parks and Recreation June 30, 2020

NARRATIVE The Ford Site Redevelopment (Ford Site) anticipates Mississippi River Boulevard (MRB) excavation at Hidden Falls Regional Park (Hidden Falls) to install a new concrete drainage pipe conveying flows from the new upstream system and creek feature. The objective of this Feasibility Study is to leverage the need for a proposed excavation at MRB to evaluate possible infrastructure alternatives that achieve multiple benefits. The desired outcome is identification of feasible options for creating a connection from the Ford Site to Hidden Falls that enhances the public realm by continuing an open channel creek while facilitating safe and accessible pedestrian movement. The study boundaries are generally defined as starting with the Hidden Falls “headwaters,” also known as Park C, at the Ford Site and extending south across MRB to the outlet at Hidden Falls. The City of Saint Paul Parks and Recreation Division (City) received STAR grant funding for the study, which is not intended to meet Minnesota Statute 429 pertaining to special assessments. A 3D scan of the existing Hidden Falls waterfall and surrounding area was performed in early May 2020 to gain a better understanding of the unique exposed bedrock wall faces, stacked limestone walls, and ledges. This 3D survey was used in conjunction with two 2D surveys - for the Ford development and for Hidden Falls Regional Park. The three surveys were spliced together giving preference to the 3D scan survey limits where any conflicts existed between the surveyed topography. The resulting spliced survey serves as the basis for this study. TKDA visited the site to review the site survey of existing conditions in an effort to identify any major discrepancies. Documents prepared by others were also reviewed, including: 90% infrastructure plans for Ford Site Redevelopment, 30% plans for Park C, 90% stormwater management plan/report/model prepared by Barr Engineering, Hidden Falls Crosby Farm Master Plan prepared in 2019, Hidden Falls Water Resource Development Feasibility Study prepared by Inter-Fluve in 2014, and geotechnical report for borings that are immediately adjacent to the MRB crossing. Based on this information, TKDA prepared four alternatives that provide varying levels of both drainage and pedestrian connectivity. These alternatives are defined in the attached plan set showing plan/profile/section views. Precedent imagery from similar projects are provided on the plan set, and as a separate attachment. Alternative 1 – 12’ BEBO structure for stream-only conveyance a. Achieves stream channel daylighting without the pedestrian underpass. Alternative 2 – 24’ CONSPAN precast bridge structure with open channel a) 150’ of additional daylighting of the creek and terraced retaining walls. b) Accessible 12’ wide trail and a meandering 4’ wide channel section. c) The alignment of the crossing follows the existing 48” culvert. d) Safety railing separates the trail from the channel. e) The CP rail drainage is intercepted upstream of the crossing.

Page 2 f) Decorative end treatments on each end of the precast bridge structure. g) A continuous cast-in-place sloped footing for the precast bridge structure. Alternative 3 – 24’ CONSPAN precast bridge structure. a. Same as alternative 2, but without the 150’ of daylighting. Instead, flows are conveyed through a 48” storm sewer. Alternative 4 – 16’ span x 12’ height box culvert a) Accommodates a 12’ wide trail with 10’ of vertical clearance b) A safety railing separates the trail from the channel. c) The alignment of the box culvert follows the proposed alignment of the 48” from the Barr Engineering design. Hidden Falls South Connection – Boardwalk steel structure a) Included with alternatives 2, 3, and 4. b) Provides accessible connection to existing trail on south side of MRB. c) Connects to existing stairs down to Hidden Falls creek. d) Design based on precedent project located in Minneapolis. e) Reduces impacts to existing trees and vegetation compared to paved trail with walls. f) Accommodates bedrock ledges and steep existing side slopes. Ryan Companies reviewed the alternatives and provided estimated costs for each, which are summarized in the table below. The costs for alternatives 2-4 include the Hidden Falls South boardwalk. Refer to the attached detailed cost breakdown for more information. Alternative

Assumes entire section is boardwalk versus partial concrete. Unsure how concrete sidewalk would be supported without retaining wall. Unit cost is based on budget received for Central Water Feature pedestrian bridge deck structure. This can be updated if $772,200 MPLS project unit cost information is available. $1,144,075 $1,189,075 $0 Replace sand section at MRB ROW. $0 Replace street section at MRB ROW $0 Replace curbs at MRB ROW $0 Assumes $25/SF for concrete unit pavers. Could adjust to $0 something less if desired. $1,650 6" unreinforced grey concrete panels. $0 Thickened grey concrete sidewalk in box culvert. $0 $1,650 $3/SF allowance added not knowing what scope is. Can be $3,000 adjusted as necessary. Added $1,000 per tree to replace what was removed. Assumes larger trees planted. Could be reduced if smaller trees are $40,000 acceptable. $43,000

Lump sum to demo trees, demo existing utilities and demo street section. Assumes natural gas line is cut and capped by Xcel at not $30,000 cost per their franchise agreement with the City. Temporary tree protection and extra SWPPP measures since we are $15,000 directly adjacent to the Regional Park. $45,000 Assumes 12' space with average height of 15ft to sound bedrock. If this moves forward, design team should engage a deep foundation $109,375 subcontractor to equipment access needs. Assumes 12' spacing with 15ft average height. 12"x12" square $262,500 encasement assumed.

$0 108.

$16,200

Assumes hand demo to protect adjacent. Includes 4 laborers x 40 hrs x $70/hr plus $10k materials/equipment. Assumes 1 day scaffold setup and safety, 3 days hand demo and 1 day cleanup. Assumes hand demo to limit risk of excessive damage. This is the wall at the southern end of the creek at Park C. We are assuming this would be concrete to ensure a good seal between the end of creek and piping structure. Concerned with water migration and long term stability if this was left as stacked stone or weather limestone. Concrete stairs at dimensions shown. Assumes thickened edge, not full frost footings. Grey concrete. Assumes salvaged stacked limestone per detail. I am uncertain how fractured the top several feet are as we get closer to the regional park, so I assumed reconstructed stacked limestone in lieu of carved limestone. A $20k allowance was added to clad the bedrock at the reconstructed falls itself. Its noted on plans, but uncertain what scope is.

$0 $16,200 $30,000 Lighting allowance. $0 Remove and reinstall existing fence.

No public Comments. III.

Permit Applications and Program Updates A) 12-023 Ford Site Demolition - Closeout (Hosch)

Mr. Kelley stated permit # 12-023 Ford Site Demolition is complete. No permanent stormwater treatment was required for this portion of the project, as no impervious surface was being added or reconstructed. The site is currently undergoing mass grading activity through CRWD Permit #20-009. Final site stabilization will be ensured through permit #20-009. The $134,000 surety was replaced by the current owner, Ryan Companies, and will be held to meet Motion 20-110: Approve Certificate of Completion for permit #12-023, Ford Site Demo.

Murphy/Sanders Unanimously Approved B) 20-013 Ford Site Alternative Permit Process (Kelley)

Mr. Kelley reviewed permit #20-13 Ford Site Alternative Permit Process. Ryan Companies purchased the 122 acre Ford Site property in St. Paul. The property was transferred from Ford Motor Company to Ryan, and 30% design plans were reviewed by CRWD in January. Sixty percent design drawings were submitted on January 21st, 2020. Final stormwater design plans are currently under review, and CRWD staff expect to issue Rule C permits at the July 8th Board Meeting. The scale, complexity and duration of the project necessitate a modified approach to issuing permits for stormwater management and erosion and sediment control. Coordination with City department review, approval, inspection and close out will be critical to minimize potential conflicts and duplication. CRWD staff discussed the proposed process to break the 122acre site into 10 individual permits to increase flexibility. Erosion Control: Permit 12-023 Ford Site Demolition. Transferred to Ryan on 1/17/2020 and provides for surface demolition, stockpiling of materials, and minor grading for retaining wall removal. $134,000 surety check was received from Ryan, and a surety return check was issued back to Ford for the same amount. This was based on 67 acres of land disturbance. Does not include approval for site mass grading or utility installation work. Permit closeout requested by staff on 06/17/2020. Permit 20-009 Ford Site Mass Grading. Issued 05/01/2020 for mass grading of the site in preparation for utilities, right of way improvements, and building sites. Additional surety of $110,000 ($244,000 total) was submitted by Ryan Companies for the expanded land disturbance beyond the original 67 acres for plant demolition. Erosion control sureties can be returned in phases consistent with the Stormwater Management permits described in the section below. All work within permitted drainage areas must be complete for this surety to be returned. Stormwater Management: Permits 20-013A through 20-013H. Stormwater Management permits will be broken into 8 smaller areas based on drainage boundaries to site BMPs as shown in the attached exhibit. These permits will be issued concurrently, but closeout will be phased based on completion of each area. Surety will be collected at $5,000/acre of the impervious surfaces within the public Right of Way, Parks, and privately owned civic spaces. Surety will be returned upon completion of all Parks and ROW, and a combination of all private parcels achieving temporary stabilization, and/or gaining coverage under a new permit for which a separate surety has been collected. Permit 2X-0XX. Individual stormwater and erosion control permit for private development parcels will be applied for, reviewed, and approved following the standard permit application process. Surety will be collected at $5,000/impervious acre impervious and returned upon confirmation of completion and BMP function. Wetland Management Permit

Permit 20-015 Ford Site Redevelopment Wetlands. Approved at the 06/03/2020 Board Meeting, this permit covers wetland impacts and the required 2:1 mitigation. A surety of $37,986 will be collected as part of the financial assurances required by WCA and the City when wetland impacts are proposed to occur prior to beginning construction on wetland replacement. Surety will be returned upon completion of the required monitoring period documenting successful establishment of wetland hydrology and vegetation. Motion 20-111: Authorize Staff to Implement the Ford Site Alternative Permit Process Murphy/Sanders Unanimously Approved C) 20-013 Ford Site Stormwater Management Plan 60-Day Review Period Extension (Kelley) The current review period for Permit 20-013 Ford Site Stormwater Management Plan expires on June 19th, 2020. The applicant requested an extension to the 60-day review period prior to the expiration. Staff will review and request permit approvals at the July 8th Board Meeting. Motion 20-112: Approve 60-day Review Period Extension for Permit 20-013 Ford Site Stormwater Management Plan to expire August 18, 2020.

AR: Approve TBI Work Order No.14 for TBI Repairs St. 28+65 to 50+72 (Eleria)

Mr. Eleria reviewed CRWD’s 11-year capital improvement plan (CIP) for TBI identifies two major CIP repairs in sections of tunnel that are in fair to poor condition. The first CIP project involves addressing areas with deteriorating concrete and exposed reinforcement, sealing holes, cracks and fractures, and removal of sediment in over 2,200 feet of tunnel near Phalen Boulevard and I-35E in Saint Paul. The estimated construction cost is $1,040,000. Barr Engineering prepared draft work order for designing repairs from TBI Station 28+65 to 50+72. The tasks include pre-design in-tunnel inspection to determine the estimated quantities for each type of repair, designing the tunnel repairs, estimating construction cost, preparing bidding/contract documents, and administrating the bidding process. Barr will utilize and modify where feasible existing repair details and specifications from previous TBI projects for the specific TBI profile, cross section and project conditions. The estimated engineering cost is $82,845. The 2020 budget for TBI Repairs is $566,250. Ms. Eleria shared an anticipated schedule for the entire project: 1) design of repairs from July – Dec. 2020; 2) bidding in late winter 2021; and 3) construction in fall 2021/winter 2022. President Collins asked for clarification of the location. Ms. Eleria replied that it is located just south of the new realignment work done in 2013. Motion 20-118: Approve TBI Work Order No. 14 in an amount not to exceed $82,845 and authorize Administrator to execute TBI Work Order No. 14 and amendments not to exceed $8,300.

AR: Approve St. Paul School of Northern Lights Stewardship Grant (Eleria)

Ms. Funke reviewed The St. Paul School of Northern Lights is seeking a $28,550 grant award from CRWD toward the development of clean water practices on their site. The St. Paul School of Northern Lights is located in the West 7th Neighborhood of Saint Paul, at 426 Osceola Ave S. The proposed project includes removing five parking stalls and replacing with a 750 square foot curb-cut rain garden that will capture 21,869 square feet of parking lot runoff annually. CRWD and RCD have provided a watershed analysis and developed construction site plans for the proposed rain garden. The 750 square foot rain garden will include two curb-cuts with pretreatment devices. The rain garden is sized to capture and infiltrate 0.6” rain events from the School’s parking lot. The rain garden will capture 11,146 cubic feet of water per year (a 73% reduction). Total suspended solids and total phosphorus will be reduced by 72% and 73%, respectively. The contractor estimates a project cost of $30,053.00. Using the Stewardship Grant Calculator, staff have calculated a total CRWD award not to exceed $28,550. This grant award is reflective of the water quality benefit this project would provide. CRWD also plans to provide educational signage for the rain garden. A minimum 5% match is required for non-profit grant applicants. The School will cover the remaining costs of the project.

Motion 20-119: Approve a grant award to the St. Paul School of Northern Lights for an amount not to exceed $28,550 and authorize the District Administrator to execute the grant agreement. Murphy/Sanders Unanimously approved Unfinished Business A)
