Rate Control Modeling Report, by City of St. Paul, not dated, recv. 3/17/21. HISTORY & CONSIDERATIONS: Griggs‐Scheffer Phase 1 was constructed under CRWD permit 20‐004. During Phase 1, the City proposed to combine both phases of the project for stormwater management due to space W:\07 Programs\Permitting\2021\21-008, Griggs-Scheffer, Phase 2\21-008 Permit Report_R3b.doc Page 1 of 4
constraints on Phase 1 and more favorable opportunities on Phase 2. The City’s plan was to maximize stormwater management on Phase 1, and then defer the remaining balance of the Phase 1 cost cap to Phase 2 of the project. Five infiltration trenches were initially proposed for Phase 1, but only two were constructed due to poor soils. 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. It is unknown if 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 for Phase 1 is 413,820 ft2 (9.5 acres). The amount of proposed impervious for Phase 2 is 418,180 ft2 (9.6 acres). The total amount of proposed impervious for both Phases 1 and 2 is 832,000 ft2 (19.1 acres). b. Volume retention required: 832,000 ft2 x 1.1 inches x 1 ft/12 inches = 76,267 ft3 Table 1. Proposed volume retention through abstraction (i.e. infiltration, reuse). Volume Volume Retention 1.1‐inch 2.5‐inch Retention Runoff Runoff BMP Provided below Required (ft3) (ft3) (ft3) outlet (ft3) Phase 1 – Bayard 4,461 2,719 6,180 Phase 1 – Watson 1,785 4,552 10,345 Trench 1 – Syndicate Street 3,738 4,221 9,592 Trench 2 ‐ Edgcumbe 10,229 31,038 70,540 76,267 Trench 3 ‐ Edgcumbe 7,166 4,640 10,545 Trench 4 ‐ Edgcumbe 5,181 4,740 10,772 Trench 5 – Highland Parkway 1,649 3,953 8,984 3 Total 34,209 ft c. Banking of excess volume retention is not proposed.

d. Infiltration volume and facility sizes have been calculated using the appropriate hydrologic soil group classification and design infiltration rate. e. The infiltration areas are capable of infiltrating the indicated 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 has been requested due to cost cap of a linear project. a. The applicant partially complied with the volume retention standard. b. The applicant did not partially comply with the volume retention standard at an offsite location or through the use of qualified banking credits. c. The applicant has not submitted money to be contributed to the Stormwater Impact Fund. d. The project is linear, and the cost cap has been reached. The combined Phase 1 and 2 projects are anticipated to have 19.1 acres of new/reconstructed impervious area, which would have a cost cap of $1,432,500 (19.1 ac * $75,000/ac = $1,432,500). The anticipated cost of Phase 1 trenches is $233,456.25 and the anticipated cost of Phase 2 trenches is $1,199,043.75 for a total anticipated project cost of $1,432,500.00. 5. Best management practices do not achieve 90% total suspended solids removal from the runoff generated on an annual basis. However, the project is linear, and the cost cap has been met. 6. A memorandum of agreement for maintenance of stormwater facilities exists between the City of St. Paul and the CRWD. Adequate maintenance access is provided for the Phase 1 and 2 underground systems. 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. It is unknown if all habitable buildings, roads, and parking structures on or adjacent to the project site comply with CRWD freeboard requirements. However, adequate conveyance has been provided to prevent flooding. 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. W:\07 Programs\Permitting\2021\21-008, Griggs-Scheffer, Phase 2\21-008 Permit Report_R3b.doc Page 3 of 4
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 16.6 acres; an NPDES permit is required. A SWPPP has been submitted. RULE G: ILLICIT DISCHARGE AND CONNECTION 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 2 Conditions Conditions: 1. Provide a copy of the NPDES permit. 2. Provide additional detail from Structure 382 downstream to the Capitol Region Watershed District‐owned storm sewer inlet to: a.

DATE: TO: FROM: RE:
May 26, 2021 CRWD Board of Managers Forrest Kelley, PE, Regulatory Division Manager Como Golf Course Stormwater BMPs Project Update
Background In 2016, CRWD was awarded a $1.76 million grant through BWSR’s Targeted Watershed Program (TWP) for work in the Como and McCarrons subwatersheds. In 2018, a feasibility study identified potential BMPs to treat stormwater runoff from the Zoo property, and CRWD contracted with Houston Engineering Inc. (HEI) to advance design on an Iron Enhanced Sand Filter Bench at the northwest Golf Course Pond, and expansion of the existing Polar Bear Infiltration Basin combined with additional underground infiltration pipes at Hole 7 near the zoo. Issues Bidding for the project extended over a three-week period from May 5th to May 22, 2020. CRWD received bids from six contractors, and the project was awarded to Rachel Contracting, LLC with a low bid of $1.42M. Construction began In July of 2020, with substantial completion achieved in September 2020. Four Change Orders were approved totaling $28,000 for a final construction cost of $1.45M. Punchlist items were completed in May 2021, and the Final Pay Application will be processed in June after CRWD and project partners confirm acceptance of infrastructure. Staff will present an overview of the project, construction highlights, and BMP performance, and answer any questions the Board may have.

Murphy/Sanders Unanimously Approved C)
AR: Approve Watershed Based Implementation Funding (Doneux)
Mr. Fossum reviewed that in FY 2018-19 Clean Water Fund (CWF) - Watershed-based Funding Pilot Program (WBIF), allocations were made to County based convene group of LGUs. The group had to determine if funding were to be distributed on a collaborative or competitive basis and the funding distribution formula. In the FY 2020-2021 CWF - Watershed-based Funding Pilot Program, allocations were made to watershed based convene group of LGUs. These groups again had to determine if the process would be collaborative or competitive and a funding distribution formula. What changed in this biennium was the addition of SWCD Annual Work Plans as eligible plans under this program. BWSR has held two meetings this late winter/spring to gather input on the next biennium of funding.
Mr. Fossum explained that since the beginning of the year, there have been a series of different meetings that have directly or indirectly focused on the WBIF. Through these discussions, Metro area Administrators believe that it would be useful to both Metro Watershed Organizations and BWSR if MAWD and local watersheds recommend a funding policy approach rather than respond or react to a state enacted policy. Metro Administrators have helped draft a recommended policy analysis and approach that was submitted to the MAWD Board. On May 3rd, the MAWD Board endorsed the Policy Analysis and Recommendations - Metro Watershed Based Implementation Funding. The core policy recommendation from this analysis is: “Funding distributed to organizations with state approved comprehensive, multiyear 103B watershed management plans that deliver on multijurisdictional priorities at a watershed scale.” Mr. Fossum shared that staff recommend that the CRWD Board draft a letter and be sent to BWSR in support of MAWD. President Collins provided an explanation of the One Watershed, One Plan and why this does not work in the metro area. Ms. Eleria added that this makes the most sense statewide. Ms. Eleria added that CRWD has spent over 2 years developing the watershed management plan. The watershed management plan was reviewed with the city’s comprehensive plans to make sure these plans correspond. President Collins asked Mr. Fossum if he had any comments to add. Mr. Fossum replied that this is about how to provide funds for local implementation. President Collins asked Ms. Funke if she had any comments. Ms. Funke had no additional comments. Manger Texer added that MAWD approved and endorsed this idea too. President Collins shared that he has had several informal conversations with BWSR administrators, and he feels good about sending a letter. Motion 21-106: Authorize Administrator to submit letter of support of MAWD WBIF Policy Analysis and Recommendation to be signed by Board President. Murphy/Sanders Unanimously Approved D)
AR: Authorize Public Comment Period for 2020 MS4 Annual Report (Funke)
Ms. Funke reviewed that as a regulated operator of a small municipal separate storm sewer system (MS4), CRWD is required to prepare and submit an annual report of activities and accomplishments associated with its stormwater pollution prevention program (SWPPP) by June 30th to MN Pollution Control Agency (MPCA). CRWD must solicit public comment on the MS4 annual report and hold an annual public meeting to present the SWPPP activities and accomplishments made each year. CRWD staff have summarized CRWD’s stormwater management activities and accomplishments in 2020 in an MS4 Annual Report Form provided by MPCA and CRWD’s 2020 Annual Report submitted to BWSR earlier this year. CRWD staff propose that the 30-day public comment period on CRWD’s 2020 SWPPP work commence on May 24th and end on June 23rd and the public meeting for presenting this work occur at the June 16th Board meeting. Announcements of the public comment period and public meeting will be published in the Saint Paul Pioneer Press and CRWD’s website. The 2020 MS4 Annual Report will be available on CRWD’s website and will be included in the Board packet for the June 16th meeting. President Collins asked for any questions or comments. There were no questions or comments.
Motion 21-107: Authorize public comment period on CRWD’s MS4 Annual Report for 2020; and approve the June 16th, 2020 Board meeting as the public meeting date for the annual report. Murphy/Sanders Unanimously Approved E)
AR: Approve Updates to the Stewardship Grant Program (Eleria)
Ms. Eleria shared that for over 15 years, CRWD’s Stewardship Grant Program has offered technical and financial assistance to property owners interested in implementing stormwater best management practices (BMPs) on their property. To date, nearly 300 BMP projects throughout the District have been constructed voluntarily through the Stewardship Grant Program. This has resulted in treating 77 acres in the District and reducing stormwater volumes by over 5,200,000 cubic feet annually. In addition, approximately 22,000 pounds of sediment and 55 pounds of phosphorus are prevented from reaching the Mississippi River each year through Stewardship Grant projects. The Planning, Projects, and Grants (PPG) Division administers the Stewardship Grant Program. Periodically, PPG staff evaluates and updates the grant program with the last one conducted in early 2018. Over the past winter, PPG staff have reviewed the Stewardship Grant Program and are suggesting changes to the program with the goals, themes, and priorities of the recently adopted Watershed Management Plan (WMP) and Diversity, Equity, and Inclusion Plan in mind. The changes to the program fall under three main categories: •
•
•
Consolidating the Stewardship Grant Program, typically for clean water projects less than $40,000, and the larger Water Quality Capitol Improvement Grant Program, typically for projects between $40,000 - $200,000, into one grant offering. The purpose for the consolidation is to be more efficient with staff time, minimize confusion about CRWD’s grants, and offer clean water project grants yearround. Offering small grant awards for native landscaping and pollinator habitat projects in CRWD’s geographic focus areas – Trout Brook, Saint Anthony Hill, and Phalen Creek sub watersheds. The intent of this new grant type is to aid with implementation of other ecologically beneficial projects that may have broader appeal in the focus areas and be more feasible to implement than rain gardens or other clean water projects that have certain site and design criteria. Offering small maintenance grants to recipients of a CRWD Stewardship Grant. Feedback received from a 2018 survey to past grantees, previous rain garden maintenance workshops and WMP development process indicated that more maintenance support from CRWD is desired.
Ms. Eleria explained how CRWD staff are proposing to offer three types of grants under the Stewardship Grant Program. The three types of grants are: 1) Clean Water Project Grants; 2) Native Landscaping Project Grants; and 3) BMP Maintenance Grants. Ms. Eleria reviewed a summary table presents each grant’s purpose, watershed management plan reference, eligibility requirements, grant award ranges, match requirements, and timelines. Ms. Eleria provided the board with a draft grant overview documents that further describe these three grant types offered under CRWD’s Stewardship Grant Program. These documents will serve as the basis for grant outreach materials. Besides these three grant types, CRWD will continue to offer grants for planning of larger clean water projects and wellsealing projects. No changes are proposed to those two grant types. PPG staff are working with Communications and Engagement staff to develop a plan for Stewardship Grant Program
outreach/promotion activities in 2021 and 2022. Activities will include participation in community events, outreach to past and current Partner Grantees, places of worship, Saint Paul District Councils and other community groups and translation of grant information materials. CRWD staff presented the proposed grant program updates to the Board Program Committee and the Community Advisory Committee. Ms. Eleria reviewed feedback in a grant program summary table. Ms. Eleria provided a review of the Stewardship Grant program and the types of projects included in the program. A higher grant award is provided to projects that service a larger area. Ms. Eleria referenced the Watershed Management Plan and provided several examples of how the grants support several goals in the plan. President Collins added that the plan looks workable. Ms. Eleria asked for any questions. Manager Murphy asked how a pollinator habitat ties in with CRWD mission to protect water quality. Ms. Eleria replied that many of the pollinator plants are native and used in absorbing rainwater runoff. Ms. Eleria added that other watershed districts offer grants for native landscapes. Mr. Fossum added that this type of work is outlined in CRWD’s ten-year plan. President Collins added that pollinator gardens provide an educational opportunity. Manager Texer and President Collins felt Ms. Eleria did a great job. Ms. Eleria replied that it has been a team effort. President Collins asked for any additional questions or comments. Manager Sanders replied that this makes CRWD full service by making sure plants are being taken care of and education is being provided to grant recipients on weeds and plant identification. Ms. Funke added that maintenance has been taken into consideration. Manager Sullivan Janzen inquired about a homeowner selling a home, and if there is an approach to following up with new homeowners and their ability to maintain the grant project. Ms. Funke replied that this year is a pilot year in looking at how to expand and assist homeowners with use of other approaches. Ms. Funke noted that CRWD has resources to volunteer groups that could assist as part of their volunteer hours. Ms. Funke added that right now, sites are managed case by case. Manager Sullivan Janzen suggested that grants be given one time for single family homes. Manager Sullivan Janzen shared concerns about a new homeowner not having the knowledge of caring for a raingarden and gardens not being taken care of properly. If a raingarden were to fall into poor condition, this would be a poor reflection on the district. Ms. Eleria noted that a curb cut raingarden would be eligible for a maintenance grant. Manager Sullivan Janzen noted that plant swaps have been discouraged because of jumping worms. Ms. Funke agreed that plant swaps have been put on pause for this reason. President Collins asked for any additional questions. Motion 21-108: Approve updates to Stewardship Grant Program. Murphy/Sanders Unanimously Approved VI.
Unfinished Business A)
HMGP Grant Update – TBI Detailed Modeling (Eleria)
Ms. Eleria provided an update of the Hazard Mitigation Grant Program (HMGP) Grant on behalf of Mr. Zwonitzer. CRWD has been awarded a grant for $375,000. Mr. Zwonitzer has been working with Barr Engineering. This is New Grant program that was recommend to CRWD by Wenck. Staff are currently working on the grant agreement and work plan. Ms. Eleria explained that a kickoff meeting will be held with seven government partners to review the scope of work and make a data request.
Ms. Eleria explained that the Grant will cover 75% of the cost of the project. CRWD will approach the partners and City of St. Paul to cover remaining 25%. Manager Texer remarked that City of St. Paul should have a contribution to the project. Ms. Eleria shared how the cities will benefit from the data provided by the model. President Collins asked if staff time would count as contribution. Ms. Eleria replied that there is a long list of data contributions required by the cities. Ms. Eleria shared that flooding concerns are a priority, and that partners have requested assistance. Mr. Fossum added that partners need to see the value of the modeling effort to identify problems and projects. President Collins stated this is great work and recalled cities talk about potential flooding when making the ten-year plan. B)

June 2, 2021 Board Meeting V. B. Action Items—Approve Grant to City of St. Paul for Como Pavilion Parking Lot Projects (Fossum)
May 26, 2021 CRWD Board of Managers Bob Fossum, Division Manager Approve Grant to City of St. Paul for Como Pavilion Parking Lot Project
DATE: TO: FROM: RE: Background
The Como Lake Management Plan (CLMP) was adopted on May 15, 2019 and the 2021-2030 Watershed Management Plan on November 4. 2020. Both plans included a capital project that install stormwater BMPs at the Como Pavilion and Clubhouse Parking Lots. The adopted 2021 CRWD Budget includes funding for the Como Parking Lot Project for an amount of $150,000. Issues Over the past several months, District staff and St. Paul Parks and Rec staff have been collaborating on planning and design of above and beyond BMPs for the Como Pavilion (North and South) and Clubhouse Parking Lots. It has been determined that only the south Pavilion Parking lot will be eligible for grant funds since the other two lots will be full reconstruction and BMPs will be required under CRWD Rules. The project is scheduled to be constructed in the Fall of 2021. The project is at 30% design currently and we are at a point where the City needs to understand what amount of funding the District may be able to provide to be able to determine the final design of the project. Staff are recommending the grant funding will be focused on the Pavilion South Parking Lot as it is the only lot that is a mill and overlay and grant eligible and has significant visibility for the public. Staff believe a grant to install BMPs is warranted, both from a load reduction standpoint (7-8 lbs/year), as well as, the demonstration/visibility standpoint. The estimated cost of BMPs and associated elements is $170,600. The project includes: a two-celled filtration rain garden, dry stream bed, rock seating area, and interpretive signs. Staff also recommend funding for the non-motorized boat launch for an amount of $16,500. This part of the project will work to achieve the recreation-based goals of the CLMP and provide better access to the lake for all of the monitoring that regularly occurs. Note: Staff have been able to confirm that the District will be able to utilize the recently approved 319 Small Watershed Funding to fund this grant award. Requested Action Approve Grant to City of St. Paul for Como Parking Lot Project for an amount not to exceed $187,100 and direct Administrator and Board President to execute a grant agreement subject to the review and approval of the Ramsey County Attorney. enc:

June 2, 2021 Board Meeting VI. Unfinished Business – C) Lake McCarrons Shoreline Assessment Project Update (Funke)
DATE: TO: FROM: RE:
May 27, 2021 CRWD Board of Managers Rachel Funke, Urban BMP Technician Lake McCarrons 2021 Shoreline Assessment Update
Background The condition of the Lake McCarrons shoreline was last assessed by CRWD in 2007. Since then, portions of the shoreline have been transformed significantly. Since 2004, 16 shoreline restorations have received CRWD and Ramsey County Soil & Water Conservation Division (RCSWCD) technical support and grant funding. Issues CRWD has contracted RCSWCD to complete a shoreline assessment in 2021. The purpose of this assessment is to evaluate and compare the current condition of the Lake McCarrons shoreline to its condition at the time of the last assessment, and to evaluate the success of past grant-funded restorations. The results of this assessment will help staff identify sections to recommend for voluntary shoreline restoration work and will allow for more effective CRWD assistance for residents who have recently expressed interest in a restoration project. The four primary tasks of the shoreline assessment are: 1. 2. 3. 4.
Review historical records of shoreline restoration efforts (January-May 2021) Conduct shoreline assessment of Lake McCarrons from a boat (Late June 2021) Assessment of previous grant-funded shoreline restorations (July 2021) Prepare Lake McCarrons shoreline assessment summary report (October 2021)
Details related to each of these tasks can be viewed in the enclosed 2021 Lake McCarrons Shoreline Assessment Proposal. The total estimate for this work is $17,524. CRWD budgeted $20,000 for this work in 2021 (CRWD budget #310-21479 Lake McCarrons Shoreline). An agreement for this work has been executed by the Administrator. Lakeshore residents, the Lake McCarrons Neighborhood Association, and the McCarrons Lakefront Alliance will be informed of upcoming plans in early June. At the same time, a survey will also be sent to previous grant recipients to provide feedback on the success of their projects. Results of the assessment and future grant promotion will be shared with these stakeholders this fall. Action Requested None, for your information.

Our mission is to protect, manage and improve the water resources of Capitol Region Watershed District.
2021 Lake McCarrons Shoreline Assessment Proposal January 20, 2021 Prepared for: Prepared for: Rachel Funke, Urban BMP Technician, Capitol Region Watershed District Prepared by: Justin Townsend, Environmental Specialist II, Ramsey County Parks & Recreation Department, Soil & Water Conservation Division Scope of Services Task 1: Review historical records of shoreline restoration efforts The Lake McCarrons shoreline has been transformed significantly since the last assessment was completed in 2007, when the lake was surrounded by largely turf grass. Documenting the full scope of the restoration efforts will be a critical first step for assessing the present state of the shoreline. Parcels, both public and private, which have been improved will be identified. Task 2: Conduct shoreline assessment of Lake McCarrons An assessment of the Lake McCarrons shoreline will be conducted during May or June 2021 to document the state of the shoreline in terms of erosivity, vegetation composition, and buffer width. An assessment of the entire lake perimeter, by parcel, will be conducted from a boat to identify and document the following: •
Erosional areas (current {three categories red-gully erosion, yellow-rill erosion, green-sheet erosion} and susceptible or similar ranking)
•
Existing shoreline (upland, shoreline, and aquatic) vegetation density
•
Shoreline vegetation buffer widths
•
A list of observed native and non-native plants identifiable from the boat on a parcel by parcel basis
The “Score Your Shore” (SYS) method developed by the MNDNR will be utilized for vegetation community assessment. While the methodology is different than the 2007 assessment this will allow future repeatability of shoreline stability. This method allows for verification of upland, shoreline, and aquatic vegetation in terms of its’ effectiveness to filter against surface runoff. Furthermore, SYS is useful in identifying the needs and to document progress over time on individual parcels.
Additionally, five (5) one-meter quadrats will be selected along the shoreline owned by Ramsey County Parks and Recreation Department to identify, quantify, and analyze plant species. This will be completed at no cost to Capitol Region Watershed District, but will be included in the final report. Task 3: Lake McCarrons Shoreline Assessment Summary The deliverables from Tasks 1 and 2 will be compiled into a final report assessing Lake McCarrons shoreline. The report will include a summary of historical restoration efforts, current shoreline conditions as listed in “Score Your Shore,” and an analysis section for plant species identified in the County parcel. The report will include maps with shoreline parcels outlined. Additionally, the report will include pictures of current conditions. Task 4: Lake McCarrons Shoreline Assessment Summary Separately from task 1-3, but to be included as an appendix within the report for those tasks, will be a technical memo based upon onsite evaluation of 16 previously restored sites. CRWD staff along with SWCD will evaluate sites for erosion, plant species, and buffer width. A system of grading and evaluation app/sheet developed by CRWD in conjunction with SWCD will be completed at each site. Recommendations to bring sites into “restored” status will be outlined within the technical memo.
