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 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 16,553 ft2 (0.38 ac). b. Volume retention required: 16,553 ft2 x 1.1 inches x 1 ft/12 inches = 1,517 ft3 Table 1. Proposed volume retention through abstraction (i.e. infiltration, reuse).

County Road B Phase 3 - Rice to Lexington

Applicant:

David Butler Xcel Energy 825 Rice Street St. Paul, MN 55117 (651) 229-2488 David.W.Butler@xcelenergy.com

Purpose:

This project will consist of the installation of two miles of new 16-inch gas main and retirement in-place of an existing 12-inch gas pipe. The new piping will be installed using open trench and horizontal direction drilling (HDD) boring techniques. All disturbed impervious surface will be replaced and no additional impervious is proposed.

Location:

County Road B from Rice Street to Lexington Ave, Roseville, MN

Applicable Rules:

C, D, and F

Variance Request:

Approve variance of 2,835 ft3 from volume retention requirement of Rule C for street impervious.

Recommendation:

Approve with 5 Conditions

EXHIBITS: 1. Civil Plans (38 Sheets), by EN Engineering, dated 1/19/21, recv. 4/1/21.

2. SWPPP Narrative, by EN Engineering, dated 2/2021, recv. 4/1/21.

3. Variance Request, by Xcel Energy, dated 3/31/21, recv. 4/1/21.

HISTORY & CONSIDERATIONS: In 2013, the Capitol Region Watershed District approved a variance from Rule C for Permit 13012 on the basis that the property that Xcel Energy was working on was owned by another entity. Xcel complied with Rule C on all property under their ownership and improved drainage patterns through impervious disconnects, vegetated conveyances, and treatment to the maximum extent practicable. The newly replaced impervious surfaces that triggered stormwater requirements were turned back to the local road authority that remains responsible for managing stormwater runoff from those impervious surfaces.

W:\07 Programs\Permitting\2021\21-016, Xcel CR B Phase 3\21-016 Permit Report_R1b.doc Page 1 of 4

In 2014, 2015, and 2016, and 2020, the Capitol Region Watershed District also approved a variance from Rule C for permits 14-011, 15-006, 16-004, and 20-007 on the basis that the property that Xcel Energy was working on was owned by another entity.

This project is being constructed entirely within the right-of-way on property not owned by Xcel Energy. This limits the extent to which Xcel can comply with permanent stormwater management requirements toward rate and volume reductions in stormwater. This project does not propose additional impervious surfaces and will restore all land disturbance back to pre-construction conditions.

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 not 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 30,928 ft2 (0.71 ac). b. Volume retention required: 30,928 ft2 x 1.1 inches x 1 ft/12 inches = 2,835 ft3 Table 1.

The applicant has requested a variance because the replaced impervious area is not owned by the applicant.

2. Best management practices do not achieve 90% total suspended solids removal from the runoff generated on an annual basis.

3. The applicant has completed the Alternative Compliance Sequence and has requested a Variance from Rule C for the 2,835 cubic feet of volume reduction and associated water quality treatment due to the lack of land ownership or control over the impervious surfaces being replaced in-kind.

4. A recordable executed maintenance agreement is not required if the variance is approved.

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.

The Minnesota Pollution Control Agency (MPCA) issued the new 2020 MS4 General Permit which became effective on November 16, 2020. CRWD is required to re-apply for authorization to discharge stormwater under the new MS4 permit by April 15, 2021. The application must include an update of CRWD’s SWPPP, which has six program categories or minimum control measures (MCMs): 1) 2) 3) 4) 5) 6)

Public education and outreach Public participation/involvement Illicit discharge detection and elimination Construction site runoff control Post-construction management and Pollution prevention/good housekeeping

Ms. Eleria shared that staff have completed the draft SWPPP application. CRWD must also submit a total maximum daily load (TMDL) worksheet that reports the District’s progress and compliance schedule toward meeting its waste load allocation (WLA) goals for phosphorus in Como Lake and sediment in the South Metro Mississippi River. Staff have developed a draft compliance plan and schedule for moving closer to meeting the WLAs of both TMDLs. Ms. Eleria provided an overview of the small MS4 permit, including new requirements. Ms. Rachel Funke, explained how the application was submitted and provided a review of the new permit requirements that CRWD will begin to implement. The new requirements included chloride management strategies, illicit discharge and pet waste management education requirements, additional guidance related to reporting and documenting illicit discharges, and additional post-construction Stormwater Management requirements. Ms. Funke added that CRWD is already compliant with many of these new permit requirements. President Collins asked for any questions.

Manager Texer inquired about the consequences if conditions are not met. Ms. Eleria replied that if conditions were not met by the MPCA, a more detailed plan would need to be submitted. Ms. Eleria felt confident that CRWD’s plan would meet the MPCA’s new requirements. Manager Murphy asked about a permit required for the last ½ mile of Trout Brook. Ms. Eleria replied that the City of St. Paul issues their own MS4 permit. Manager Murphy asked about the capturing trash & material flowing from storm drains and flowing into lakes and rivers. President Collins inquired about debris in Trout Brook and if it is captured. Ms. Eleria replied that there is debris in the tunnel and trash removal is included in the ten-year management plan. Manager Murphy inquired about pet wastes at dog parks.

Ms. Eleria replied that new requirement in the permit requires outreach and education. CRWD plans to collaborate with partners and encourage owners to pick up after pets. President Collins asked about any state guidance on chloride management. Ms. Funke replied that CRWD is promoting chloride management with good housekeeping thru education and outreach efforts. Manager Sullivan Janzen added that she is concerned about trash and hopes the District can be aggressive about removing it and helping people find alternatives to throwing on the ground. Mr. Simonet added that many bottles can be found at the Willow Reserve.

April 14, 2021 CRWD Board of Managers Nate Zwonitzer, Water Resource Project Manager Authorize Notice of Award and Order Construction of 2021 Boulevard Rain Garden Project

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. Boulevard rain gardens were identified as part of CRWD’s Clean Street Initiatives for the purposes of the grant. CRWD promoted rain gardens in the Como Subwatershed and McCarrons Subwatershed, and designs were developed by Ramsey County Soil and Water Conservation Division. In early March 2021, CRWD’s Board of Managers approved plans and authorized bidding for the 2021 Boulevard Rain Garden Project.

Issues The bidding period for the project extended over a four-week period from March 5 – April 2, 2021. During bidding, one rain garden needed to be eliminated and another downsized due to previously unidentified utility conflicts. Bid quantities were updated via a bid addendum to include 24 rain gardens on 23 properties. CRWD received bids from six contractors ranging from approximately $195,000 to $406,372.

The project estimate was $199,000 and two bids were within $5,000 of the estimate. A bid summary table is below.

Contractor Name Bid Amount Order Minnesota Native Landscapes, Inc. $194,944.00 1 Outdoor Lab Landscape Design, Inc. $203,910.65 2 Meyer Contracting, Inc. $263,833.50 3 Sunram Construction, Inc. $273,470.10 4 JL Theis, Inc. $286,958.74 5 Urban Companies $406,372.00 6 Minnesota Native Landscapes, Inc. (MNL) submitted the lowest bid. CRWD staff have reviewed and discussed the bid and verified MNL’s responsiveness and qualifications for this project. All homeowner agreements will be secured before construction begins, which is anticipated to occur in May with a completion deadline of June 25, 2021.

April 21, 2021 Board Meeting V. Action Item - D) Approve Consultant for TBI Detailed Modeling Project (Zwonitzer)

DATE: TO: FROM: RE:

April 14, 2021 CRWD Board of Managers Nate Zwonitzer, Water Resource Project Manager Approve Consultant for the TBI Detailed Modeling Project

Background CRWD’s 2021 budget include funding to conduct additional detailed modeling of Trout Brook Interceptor (TBI) and the 8,150-acre Trout Brook subwatershed. This expands on the Atlas-14 model update completed in 2018 by adding spatial resolution to the model particularly in the City of Saint Paul and includes evaluating storm sewer capacity issues, areas of flooding, and watershed pollutant loading. The results will help CRWD and its partners identify and prioritize future mitigation efforts. The CRWD Board of Managers previously reviewed a draft project scope and approved a $375,000 grant application for the effort through a State and Federal Hazard Mitigation Program in November 2020 and authorized an RFP for the project in February 2021.

Issues In March, CRWD received proposals to complete the modeling project from three consulting firms: HZ United (DBE), Barr Engineering, and HR Green. All three proposals met the requirements of the RFP and costs were within the anticipated level of effort ranging from $382,616 - $411,579. Proposals were independently evaluated and scored by a review team consisting of three CRWD staff as well as one staff from the City of St. Paul’s Sewers Division, a key stakeholder with extensive experience working with consultants on highly technical modeling efforts.

Independent proposal scoring identified Barr Engineering (proposal enclosed) as the top proposal in all review categories, particularly personnel qualifications and relevant experience. The review committee also agreed the project approach and allocation of staff resources outlined by Barr was the best fit for this project. Staff recommend approving Barr Engineering as the consultant and are seeking approval of an agreement amount for the project base tasks. In addition, staff recommend the Board give authorization to the Administrator for amendments to conduct the optional tasks outlined in the proposal if they are deemed necessary. CRWD has budgeted $150,000 for the project in 2021 (CRWD Project #315-21554) and will budget an additional $250,000 in 2022. In addition to the potential federal grant for this project, CRWD staff will approach City and County partners for contributions towards this effort. Work will begin on the project shortly and is anticipated to be completed by July 2022.

Action Requested Approve Barr Engineering as the consultant for the TBI Detailed Modeling Project and authorize the Administrator to execute an agreement not to exceed $320,310 and any amendments to the agreement up to $84,020. enc.

Proposal for Trout

Brook storm sewer interceptor detailed XP-SWMM and P8 modeling

Prepared for Capitol

Region Watershed District

Submitted by Barr Engineering Co. March 11, 2021

March 11, 2021 Nate Zwonitzer Water Resource Project Manager Capitol Region Watershed District nzwonitzer@capitolregionwd.org Re: Request for proposal for Trout Brook storm sewer interceptor detailed XP-SWMM and P8 modeling Barr Engineering Co. is pleased to submit our proposal to enhance the existing hydrologic and hydraulic (H&H) XP-SWMM model of the Trout Brook interceptor (TBI) subwatershed with additional detail, and to develop a P8 model of the same area. We believe that Barr is best suited to assist Capitol Region Watershed District (CRWD) on this project because our: Knowledge of your data and modeling preferences means that we’re ready to go. Since 2010, Barr has developed and made updates to the TBI H&H model. In 2018, we successfully calibrated the model to assess and prioritize flooding areas throughout the tunnel system, enabling CRWD to plan infrastructure improvements. Our long history with the model has allowed us to develop a familiarity with your data and modeling preferences, as well as close relationships with project stakeholders. We have also performed detailed modeling for all the cities in this specific subwatershed, so we are very familiar with their data quality and modeling needs.

Experience with detailed urban watershed modeling will give you a cost-effective, reliable, and useful assessment and decision-making tool. Our proposed team members (most of whom have already completed multiple modeling projects in Saint Paul) have developed models for tens of thousands of acres of highly urban land in Saint Paul and Minneapolis. In recent years, we have built more than a dozen detailed models for urbanized areas similar to and including the TBI watershed area; these models helped our clients assess localized (street intersection level) and regional flooding in order to make decisions resulting in capital projects to reduce flooding and improve water quality. Our modelers are continuously building and improving our model input generation and QA/QC tools, allowing us to become more efficient and cost-effective each year while creating more accurate and useful models.

Deep bench of H&H experts with extensive XP-SWMM knowledge will get your project done right and on time. With more than 40 engineers and scientists experienced in H&H modeling and calibration of urban watersheds, we will get it right the first time—on budget and on schedule. Our expert modeling team is often called on to review others’ models and suggest modifications to improve reliability of results, and our models have earned the respect of clients, regulators, and outside reviewers. Barr’s modeling expertise and understanding of your tunnel system make us uniquely qualified to provide CRWD with the reliable tools and results that you and your partners need.

Thank you for the opportunity to propose on this work. We look forward to working with you on this project. If you have any questions regarding our proposal, feel free contact me (952-832-2854, ncampeau@barr.com).

Our breadth and depth of experience means that we can provide an innovative solution to any water resources challenge we encounter. Barr is proud to have served Capitol Region Watershed District (CRWD) for more than a decade in support of analyzing, maintaining, and improving its water resources and storm sewer infrastructure.

Barr has unparalleled experience developing detailed hydraulic, hydrologic, and water quality models in the Twin Cities metropolitan area, having developed and/or updated more than 150,000 acres of total model area in this region.

Project approach Barr understands that CRWD and project partners wish to develop detailed watershed modeling of the Trout Brook interceptor (TBI) watershed to evaluate storm sewer (TBI, municipal, and other) capacity issues, areas of flooding and flood mitigation opportunities, watershed pollutant loading and water quality improvement opportunities, and capital improvement needs. This study area spans approximately 8,150 acres and encompasses land within the following cities and organizational jurisdictions: Saint Paul, Falcon Heights, Roseville, Little Canada, Maplewood, Ramsey County, Minnesota Department of Transportation (MnDOT) right of way, University of Minnesota, and CRWD. To achieve these goals, the Barr team proposes to expand on the existing Atlas 14 hydrologic and hydraulic (H&H) XPSWMM TBI model (completed by Barr) by improving the spatial resolution of the model to the scale of intersections and groups of catch basin inlets (i.e., catch basin clusters). Additionally, Barr proposes to create detailed water quality P8 models spanning the study area, utilizing utility storm sewer data, stormwater best management practice (BMP) data, bathymetric survey information, site development plans, and other information provided by CRWD and project partners.

After a complete review of provided information, we will develop strategies to address data gaps, including performing field review and survey. Using best-available data, Barr will create study area models and provide detailed summaries of model inputs, outputs, and results to help the city identify areas prone to localized and regional flooding, storm sewer capacity issues, water quality improvement opportunity areas, and capital improvement opportunities within the study area. Additionally, utilizing Barr’s experience with model calibration within the TBI watershed, we will review CRWDcollected monitoring data and coordinate with CRWD and project partners to evaluate the benefit of calibrating the XP-SWMM and P8 models.

Scope of work The following subsections align with the primary work tasks outlined in the RFP. Challenges, opportunities, and unique considerations related to each task are identified within each respective subsection.

Task 1: existing data collection and review Using data provided by CRWD and project partners, obtained from study area organizational jurisdictions (e.g., MnDOT, Ramsey County, etc.), and gathered from publicly available sources, Barr will create a water resources data inventory of the storm sewer infrastructure, culverts, ditches, low areas, lakes, ponds, wetlands, BMPs, and other drainage features within the study area.

Based on initial review of available datasets, the following assumptions pertain to available geographic information system (GIS) storm sewer utility datasets and form the basis of our proposed scope of work, schedule, and budget.

CRWD: CRWD maintains a spatial dataset of water quality BMPs within the watershed district jurisdictional boundary. We will request and review the spatial BMP dataset within the TBI watershed. BMPs will be identified and cross-referenced against other publicly available datasets. Barr will coordinate with CRWD and project partners to obtain BMP information for regional and public BMPs as needed.

Barr recently completed detailed XP-SWMM and P8 modeling of the 4,000acre Saint Anthony Park watershed for the City of Saint Paul.

City of Saint Paul: Saint Paul comprises approximately 65 percent of the TBI study area. We understand that the city’s storm sewer pipe system map (ArcGIS files) includes information on the location, size, material type, and invert elevations of a majority of storm sewers, catch basins, manholes, and pump stations in the study area. Barr is familiar with the city’s GIS storm sewer data and has used it to create several watershed models (H&H and water quality) for the city and CRWD. Additionally, data for private storm sewer connections will be accessed from the city’s public works portal to inform subwatershed delineation (see task 2).

Other project partners and sources: The table below provides a summary of percent contribution of all municipalities and organizational jurisdictions within the TBI study area and assumptions regarding available storm sewer utility datasets. Assumptions outlined in the table are based on Barr’s experience working with datasets for similar projects in adjacent study areas, including for CRWD, the City of Saint Paul, and the Ramsey-Washington Metro Watershed District.

Organization

TBI study area contribution (%)

Spatial storm sewer utility dataset assumptions

Saint Paul

58.0%

Complete and populated spatial dataset (elevations and diameters)

Roseville

20.1%

Complete spatial dataset, but no elevation data (diameters only)

Maplewood

6.9%

Complete spatial dataset, but no elevation data (diameters only)

MnDOT

6.0%

Incomplete, partially populated dataset; record drawings available

Ramsey County

5.5%

Incomplete; often populated in overlapping municipal datasets

Falcon Heights

2.7%

Complete spatial dataset, but no elevation data (diameters only)

Little Canada

0.7%

Complete spatial dataset, but no elevation data (diameters only)

Based on the storm sewer utility dataset assumptions listed above, it is anticipated that there will be invert elevation data gaps in more than 30 percent of the TBI watershed. For this reason, it will be critical to work with CRWD and project partners to develop strategies to fill data gaps. Potential strategies include conducting field surveys, reviewing record drawings, developing invert assumptions using relative depth and network-based data assumptions, and reducing model resolution in areas of significant data gaps. We will review existing data gaps in a kickoff meeting with CRWD and project partners. During this meeting, we will ask project partners to review and attempt to fill data gaps and discuss strategies to fill remaining data gaps.

In addition to GIS storm sewer utility datasets, Barr assumes that CRWD and project partners will provide the following information, if available:

Barr Engineering Co. | Page 4

▪ ▪ ▪ ▪

Best-available record drawings for lake/pond outlets, pump information, and other complex storm sewer infrastructure Lake and pond bathymetric data (e.g., ArcGIS files, PDFs with bathymetric contours, etc.).

Building structure footprints (ArcGIS files; if not available, LiDAR-derived building outlines will be used) BMP inventory information

After review of available storm sewer utility datasets, Barr will conduct field investigations to a) perform relative depth survey to fill critical data gaps, b) collect average pond depths, and c) field verify subwatershed divides. Relative depth survey involves recording depth to invert from rim surface and estimating invert elevations by comparing to LiDAR. Barr will collect and use average pond depth to estimate bathymetric volume for any water bodies without bathymetric volume survey data. This scope includes up to five days of fieldwork to verify storm sewer information and collect required data for water quality modeling.

In addition to storm sewer utility data and field collected data, Barr will compile best-available hydrologic datasets— including soils information (e.g., the Natural Resources Conservation Service’s Soil Survey Geographic Database (SSURGO) data), imperviousness information (e.g., Ramsey County’s 2015 imperviousness dataset), and land use data (e.g., the University of Minnesota’s Twin Cities Metropolitan Area (TCMA) land use dataset)—to create a detailed hydrologic model for use in both XP-SWMM and P8 modeling. High-resolution (i.e., 1-meter) Ramsey County and Hennepin County LiDAR datasets will be used to define surface storage throughout the study area.

Task 1 deliverables: Kickoff meeting to review data gaps and discuss strategies to fill data gaps Digital storm sewer base map (PDF) of the study area highlighting data gaps

▪ ▪

Task 1a (optional): bathymetric survey Bathymetric survey is performed to determine the bathymetric volume of ponds, lakes, and wetlands. This data is critical to water quality modeling efforts and can be used to evaluate sedimentation rate and plan sediment management projects. If CRWD and project partners elect to collected detailed bathymetrical data for water bodies within the study area, Barr will coordinate efforts to help determine: ▪ ▪

Which lakes, wet ponds, and wetlands to survey as identified by coordinating with CRWD and partners What parties will be responsible for bathymetric surveys on each water body (i.e., CRWD, partners, or Barr)

If selected to perform bathymetric surveys, two Barr staff will collect survey data, digitize survey data, create bathymetric digital elevation models, and incorporate collected bathymetric data into modeling efforts for up to five water bodies.

Task 1a (optional) deliverables: ▪ ▪

Digital elevation models of collected bathymetric data Figures (PDFs) showing bathymetric contours for surveyed water bodies

Task 2: delineate subwatersheds and develop XP-SWMM inputs CRWD originally developed an XP-SWMM model of the TBI watershed in 2005. At that time, the goal of model development was to accurately model runoff conveyance to the TBI tunnel. Rather than explicitly modeling all tributary storm sewer trunklines, many developed areas were grouped into large drainage areas representing flow to major stormwater conveyance features, resulting in an average subwatershed size of approximately 40 acres. While this strategy accurately routes inflows to the TBI tunnel, it does not allow for detailed flood inundation mapping or storm sewer capacity evaluation in a majority of the study area.

To achieve model update goals outlined in the project approach, Barr will add spatial resolution to the TBI model by evaluating, refining, and subdividing existing drainage divides throughout the TBI watershed. In residential portions of the study area, subwatershed divides will typically be delineated to catch basin clusters (intersection level) that connect to the trunk storm sewer system at a single manhole. The average residential

Barr completed detailed H&H and water quality modeling of the Willow Reserve wetland within the TBI watershed and generated flood mitigation and water quality improvement alternatives.

Barr Engineering Co. | Page 5

subwatershed size is expected to be about 2 to 4 acres, with a maximum typical subwatershed size of 10 acres for park, golf course, and industrial areas. Subwatershed divides will initially be delineated using Barr proprietary, automated ArcGIS processing techniques. Barr will then review and adjust all subwatershed divides as necessary to accurately reflect routing features such as curb and gutter, road crests, and probable building drainage patterns (when not defined by Saint Paul permit data). Additionally, Barr will review and incorporate Saint Paul private storm sewer connection permits and site plans defining Saint Paul rate control areas into subwatershed delineations. We have extensive experience incorporating Saint Paul permit and rate control information into detailed XP-SWMM modeling and have developed a methodology to streamline this approach.

After presenting draft subwatershed divides to CRWD and project partners for review and incorporating one round of comments and revisions, Barr will generate hydrologic inputs using the methodology and data sources from the TBI Atlas 14 update and calibration project (Barr, 2018). Calibration methodology developed for the 2018 calibration project will not be applied initially but will be evaluated during XP-SWMM model calibration review (see task 3).

Task 2 deliverable: Figures (PDFs) showing draft subwatershed divides for CRWD and project partner review

▪

Task 3: XP-SWMM model update Barr will refine and add detail to the existing TBI watershed model by incorporating spatial storm sewer datasets (task 1), received and collected bathymetric data (task 1a, optional), and updated subwatershed divides and hydrologic information (task 2). To verify consistency with the existing TBI XP-SWMM watershed model, we will incorporate spatial and hydrologic datasets into a one-dimensional XP-SWMM model consistent with modeling methodology outlined in the TBI Atlas 14 update and calibration project (Barr, 2018). Barr recommends that the TBI watershed model remain a onedimensional model, as one-dimensional modeling allows for efficient and economical watershed evaluation in line with project goals, simplifies the process of future model updates, and is consistent with partner organization requirements (see task 3a: conversion to Saint Paul methodology). Barr has extensive knowledge of the existing TBI XP-SWMM watershed model and has been involved with many major model update projects since creation of the TBI model in 2005, including: ▪ ▪ ▪ ▪ ▪

TBI calibration project (2012) Model revisions associated with the TBI realignment project and MnDOT I-35E/Cayuga project (2012-2013) Farrington and Cottage Streets subwatershed study (2014) Willow Reserve subwatershed study (2016) TBI Atlas 14 update, calibration, and flooding area prioritizations project (2018)

Using our unparalleled experience with the TBI watershed XP-SWMM model, we will verify that model updates are incorporated thoughtfully, while preserving critical model updates incorporated during previous modeling efforts.

To achieve goals outlined in the project approach, Barr will generate surface storage curves for all subwatersheds to allow for complete capture of all significant surface storage areas within the TBI watershed. We will model the Atlas 14 500-year, 24-hour design event and capture runoff volume using an approach consistent with the TBI Atlas 14 update and calibration project (Barr, 2018). We will model surface storage and overland conveyance channels to capture runoff generated by the 500year event. Barr has developed methodology and GIS processing techniques to quickly capture runoff volume while avoiding storage and conveyance modeling errors (e.g., “double counting” of storage by modeling surface conveyance channels through modeled storage areas).

Information related to water quality BMPs (e.g., bathymetric contours for wet ponds) will be incorporated into the XP-SWMM model to achieve as much consistency between the models as possible, and to more efficiently create the study area P8 model after completion of the XPSWMM model. The CRWD spatial dataset of water quality BMPs within Barr successfully calibrated the TBI watershed the watershed district jurisdictional boundary will be reviewed, and all XP-SWMM model in 2018. significant regional BMPs will be explicitly modeled.

Barr Engineering Co. | Page 6

After capturing volume for the 500-year event, Barr will run the Atlas 14 two-, 10-, and 100-year events and generate preliminary flood inundation mapping for all modeled events. After review of preliminary flood inundation mapping and flood prioritization areas identified in the TBI Atlas 14 update and calibration project (Barr, 2018), we will perform a “partial calibration” review. Specifically, we will apply calibration changes from the 2018 calibration project and utilize the 2018 rainfall events and monitoring data and evaluate 2018 calibration updates. Uncalibrated modeling results, comparison of results within flood prioritization areas, and partial calibration results will be shared with CRWD and project partners at a draft XP-SWMM review meeting. A goal of this meeting will be to determine whether modeling efforts should proceed with uncalibrated modeling inputs or partial calibration inputs, or if the model should be recalibrated based on 2020 conditions and monitoring data. Prior to this meeting, Barr will perform an initial review of 2020 precipitation and monitoring data and compare monitoring rating curves developed from 2018 monitoring data to determine the level of effort and value of updating model calibration.

Task 3 deliverable: ▪ ▪

Task 3a: XP-SWMM model conversion to Saint Paul methodology Saint Paul requires that municipal XP-SWMM models be constructed following guidance outlined in the City of Saint Paul XP-SWMM Hydrology and Hydraulics Development Guidance document. Following the approach developed for Saint Anthony Park watershed modeling (Barr, 2020), we will use hydrologic spatial datasets to calculate SCS curve number hydrologic parameters for all subwatersheds within the study area, and we will convert vertical spatial datum of the model (NAVD 88) to the Saint Paul datum, as needed. As outlined in task 2, Saint Paul rate control site plans will be reviewed and incorporated into study area subwatershed divides. For rate control area, we will generate hydrologic parameters to achieve 1.64 cfs/acre for the TP-40 100-year, 24-hour event using methodology that we successfully developed for the Saint Anthony Park watershed modeling project. We will then model Saint Paul Atlas 14 design storms (two-, five-, 10-, 25-, and 100-year 24-hour events) and separate the TBI watershed model into sub-2,000 element models (based on Saint Paul’s XP-SWMM license element limit). Tailwater conditions and inflows between sub-model areas will be incorporated and tracked following methodology that Barr developed for the Saint Anthony Park watershed modeling project.

Task 3a deliverables: ▪ ▪

XP-SWMM models converted to meet Saint Paul modeling methodology requirements Meeting with CRWD and Saint Paul to review converted models

Task 4 (optional): XP-SWMM model calibration Based on review of “partial calibration” results (task 3), CRWD and project partners may determine that updating model calibration is necessary to improve performance. Having successfully calibrated the TBI watershed XP-SWMM model in 2018, Barr has extensive and recent experience processing CRWD monitoring data, developing spatially variable rainfall inputs, identifying calibration strategies, and calibrating H&H assumptions within the TBI watershed.

We will review and process CRWD-collected precipitation and flow monitoring data to determine if data can be used for XP-SWMM model calibration. After, Barr will identify candidate rainfall events for calibration efforts (two calibration events, one validation event). To capture the spatial variability of rainfall across the 8,150-acre study area, we will utilize the rainfall monitoring network to generate spatially variable rainfall distributions for subwatersheds throughout the study area. Utilizing results for the “partial calibration” effort (task 3), we will identify calibration strategies and implement hydraulic and/or hydrologic updates to attempt to recalibrate the model. Calibration efforts and updates will be reviewed with CRWD and project partners and extensively documented within the final project report (task 8).

Task 5: P8 model development Barr will use the completed XP-SWMM model described in task 3 (or the calibrated XP-SWMM model described in the optional task 4) to develop P8 models spanning the TBI watershed. We anticipate, based on the size of the study area and subwatershed and device limitations of the P8 water quality program (i.e., maximum number of subwatersheds: 250; maximum number of devices: 75), that the following steps will need to be taken: Barr Engineering Co. | Page 7

▪ ▪

Consolidate XP-SWMM subwatersheds (i.e., merge subwatersheds in areas of similar land use) Divide the study area into a number of P8 model areas (10 to 12) along logical major divides (pipeshed divides, subwatershed divides, etc.) to avoid exceeding the P8 subwatershed count and device count limits

In addition to merging XP-SWMM subwatersheds and determining logical model breaks, we will need to estimate any BMP parameters not determined from available data sources (e.g., pond bathymetric volumes based on area and assumed depth, infiltration rates for surface and subsurface infiltration BMPs, etc.).

Barr will develop the P8 models to simulate runoff, total suspended solids, and total phosphorus loading for a 50-year period. We have modeled the 50-year period from 1949 through 1997 for previous Saint Paul modeling efforts but will coordinate with CRWD and project partners to determine which 50-year period should be modeled.

H&H modeling assumptions will be developed using datasets described in task 3. As outlined in task 3, the CRWD spatial dataset of water quality BMPs within the watershed district jurisdictional boundary will be reviewed, and all significant regional BMPs will be explicitly modeled. Specifically, the models will be developed to account for existing regional BMPs and significant BMPs associated with private developments but will not account for all private BMPs (e.g., residential rain gardens, other small developmentscale BMPs not anticipated to have a significant impact on regional water quality, etc.).

The model will incorporate the P8 modeling that Barr performed for the Willow Reserve watershed improvement feasibility study (Barr, 2016) as well as any other P8 modeling efforts that CRWD developed for the Como Lake and Lake McCarrons subwatersheds.

Barr developed a network of P8 models spanning the Saint Anthony Park watershed and mapping showing pollutant loading rates pre- and postBMP removal.

We will provide draft results (maps showing areas of elevated areal pollutant loading, BMP treatment efficiency, and postBMP removal pollutant loading (i.e., “effective loading”), which can be used to help prioritize and target BMP implementation) to the city for review and will meet with city staff at your offices to review the draft results and receive comments. We will incorporate comments into the final P8 models. In addition to P8 model development, Barr will review CRWD monitoring data to determine if P8 calibration is possible and to determine the level of effort and value of performing P8 modeling calibration (see optional task 6).

Task 5 deliverables: ▪ ▪

Meeting with CRWD and project partners to review draft P8 model results Figures (PDFs) showing P8 model results (pollutant yield, pollutant reduction, and pollutant effective loading)

Task 6 (optional): P8 model calibration Based on review of P8 results and available monitoring data, CRWD and project partners may request that developed P8 models be calibrated to collected monitoring data. Barr has extensive experience calibrating P8 models to collected event-based water quality data and will assist CRWD and project partners in determining the level of effort and value performing model calibration (see task 5). Additionally, we can help process and review collected monitoring data as needed, including converting event-based monitoring into total loading values for monitored rainfall events.

Using our experience calibrating regional water quality models, we will review monitoring data, identify candidate calibration parameters (e.g., hydrologic parameters, particulate and pollutant loading parameters, etc.), and implement model parameter updates to achieve model calibration. Calibration efforts and updates will be reviewed with CRWD and project partners and extensively documented within the final project report (task 8).

Task 6 (optional) deliverables: ▪ ▪

Meeting with CRWD and project partners to review P8 calibration efforts Figures (PDFs) showing calibrated P8 model results (pollutant yield, reduction, and effective loading)

Task 7: update TBI flood prioritization As an aspect of the TBI Atlas 14 update and calibration project (Barr, 2018), CRWD and Barr developed a scoring strategy to rank and prioritize nine flood areas adjacent to the TBI. The prioritization strategy assigns a scoring value to structural and infrastructure flood impacts for Atlas 14 design events. Based on the return interval of the Atlas 14 event and inundation consequence score, a single probability-weighted impact score was calculated for each flood area to inform prioritization of future flood mitigation efforts.

Barr Engineering Co. | Page 8

Using the updated XP-SWMM model, Barr will evaluate and re-score the nine originally identified flood prioritization areas. Additionally, we will coordinate with CRWD and project partners to evaluate and score any newly identified flood prioritization areas. For the purpose of this scope, it is assumed that a total of 15 flood areas will be included in this updated flood prioritization effort. After generating updated probability-weighted impact scores for each flood area, Barr will identify next steps for evaluating and identifying flood mitigation efforts for the top three flood priority areas. Next steps and recommendations will be summarized in the final project reporting (task 8).

Task 7 deliverables: Meeting with CRWD and project partners to identify flood prioritization areas Table summarizing updated scoring values for all flood prioritization areas

Task 8: final report

Barr and CRWD developed a flood prioritization strategy for nine flood areas in the TBI watershed.

Barr will prepare draft and final reports, including electronic deliverables, consistent with reporting and deliverables developed for the TBI Atlas 14 update and calibration project (Barr, 2018). The report will include the following: project background, documentation of all XP-SWMM model updates and calibration, documentation of P8 model development and calibration, tables summarizing BMP performance, documentation of the updated flood prioritization analysis, and all other figures and deliverables discussed in tasks 1 through 7.

Trout Brook interceptor modeling and calibration Client: Capitol Region Watershed District CRWD owns and operates a 6-mile storm sewer tunnel (the TBI) in Saint Paul that services 8,150 acres, including two major lakes. Since 2010, CRWD and Barr have developed and made updates and improvements to an H&H model of the tunnel system. In 2018, we successfully calibrated the model to five flow monitoring locations distributed throughout the tunnel system. Barr then modeled and evaluated design rainfall events up to the 500-year event, which includes the mid-century climate change projection for the 100-year event—about 40 percent higher than today’s 100-year event. Using the flooding impacts from the two- through 500-year events, Barr assessed the likelihood and potential impacts of flooding at nine locations, developing a composite risk score in order to prioritize the flood areas. CRWD will use the calibrated model, inundation mapping, and prioritized flood impact analysis to plan and evaluate infrastructure improvements.

Saint Anthony Park modeling Client: City of Saint Paul The City of Saint Paul hired Barr to develop detailed H&H and water quality models for the 4,000-acre Saint Anthony Park Tunnel watershed spanning portions of Saint Paul, Lauderdale, Roseville, and Falcon Heights. Utilizing Saint Paul modeling guidance, we developed a high-resolution hydraulic XP-SWMM model of the watershed to the resolution of intersections and individual inlets.

Barr obtained, reviewed, and incorporated Saint Paul stormwater permit data and site plans outlining areas meeting Saint Paul rate control requirements (1.64 cfs/acre) into subwatershed divide development and H&H modeling. Using the developed XPSWMM models, we developed water quality P8 models to evaluate watershed pollutant loading and the effectiveness of water quality BMPs within the study area. With detailed modeling complete, we developed pipe capacity, inundation, and pollutant loading and reduction mapping to help identify and evaluate capital improvement needs and water quality opportunities throughout the study area. Additionally, coordinating with the city, Barr analyzed and reviewed stormwater runoff and pollutant loading from MS4s within the study area to help identify and advise cost-sharing opportunities for future capital improvement and water quality projects.

Northern Columbia Heights, Fridley, and Hilltop H&H and water quality modeling and calibration Client: Mississippi Watershed Management Organization The MWMO hired Barr to develop H&H and water quality models for a 2,300-acre watershed spanning portions of Columbia Heights, Fridley, and Hilltop. We developed a high-resolution model of surface hydrology and the storm sewer utility network, and calibrated the model using pipe monitoring data collected by the MWMO as well as NEXRAD rainfall data adjusted using a network of rainfall monitoring gauges surrounding the watershed, which included several small lakes. After successfully calibrating the model, Barr developed detailed inundation, impacted structure, and pipe capacity mapping for a variety of design events, which will be used to guide and prioritize future capital improvement projects. Using the calibrated H&H model, we developed P8 water quality models to evaluate pollutant loading and the effectiveness of water quality BMPs throughout the watershed. Using results from the P8 models validated to calibrated H&H results, we developed detailed mapping of watershed and effective pollutant loading to help prioritize and target areas within the watershed for future BMP implementation and water quality improvements.

North Minneapolis XP-SWMM modeling Client: City of Minneapolis Barr developed a detailed one-dimensional XP-SWMM model for North Minneapolis. The City of Minneapolis and MWMO intend to use the model to identify inundation extents for storm events, identify potentially flood-prone structures, assess performance of existing stormwater assets and identify areas of concern, prioritize areas for upgrades and BMP implementation, and evaluate development impacts. Barr converted a region of the model to a two-dimensional model to verify peak water levels in flood-prone areas, and to further understand complex surface flow patterns during large events. We presented this two-dimensional modeling work in urban environments at the 2018 Water Resources Conference. Under a separate project for the MWMO, Barr developed a water quality P8 model for the study area.

LETTER FROM ADMINISTRATOR From the Administrator: While adjusting to the challenges faced during 2020 CRWD accomplished several keystone projects, approved major plans, and welcomed new staff members and a new board manager. Despite the restrictions surrounding COVID-19 and changing work environments the District continued to improve water quality for our lakes and the Mississippi River.

The District completed two major in-lake treatments at Como Lake in spring 2020. An herbicide treatment was conducted in April to target curly-leaf pondweed, an unwanted invasive aquatic plant. In May, alum (aluminum sulfate) was applied in the lake to reduce the internal loading of phosphorus from the bottom sediments. Initial water quality reports after the treatments were promising, and nearly met the state standard for phosphorus for the first time on record.

In addition to in-lake treatments, the District began construction of two clean water projects at the Como Golf Course.

Combined the projects will prevent 55.1 pounds of phosphorus from entering Como Lake each year.

In spring 2020 construction began on the Highland Bridge redevelopment at the former Ford site in Saint Paul. Several stormwater management features across the 122-acre site will reduce pollution entering the Mississippi River from this area each year by an estimated 94% of total suspended solids and 75% of phosphorus. The redevelopment also includes a central water feature and the reimagined Hidden Falls Creek with a connection to Hidden Falls Regional Park underneath Mississippi River Boulevard.

The revised Lake McCarrons Management Plan was adopted in April 2020 with input from residents and community partners. The plan continues CRWD’s commitment to maintaining the water quality and biological health that support recreational uses of Lake McCarrons in Roseville.

In September 2020 CRWD began construction to improve flood control and pollutant removal at Seminary Pond, a regional stormwater pond in Lauderdale. The pond serves a drainage area across multiple cities and represents the first collaboration between CRWD and this group of partners.

The Diversity, Equity, and Inclusion (DEI) Plan was adopted by the Board of Managers in September 2020 and incorporated into the new Watershed Management Plan. Belinda Gardener was instrumental in guiding the plan’s development and was announced as CRWD’s first Diversity Coordinator.

The Board of Managers adopted the District’s new Watershed Management Plan in November 2020. The plan will guide District actions over the next 10 years. It was developed in collaboration with District partners and community members who serve key roles in achieving District goals. The final period of the Plan review and engagement required adaptations for COVID-19 restrictions with virtual meetings and online comment forms. It would be a major accomplishment in any year and is especially impressive during this unprecedented year.

I am proud of the work we accomplished together in 2020 while adapting to ever-changing conditions. I would like to express my appreciation to CRWD’s Board of Managers and Community Advisory Committee; the Cities of Saint Paul, Falcon Heights, Maplewood, Roseville, and Lauderdale; Saint Paul’s District Planning Councils; Ramsey County, community partners, and residents for your continued support in helping protect and improve water quality in our lakes and the Mississippi River.

Respectfully,

Mark Doneux Mark Doneux, Administrator

In 1998, a small group of dedicated citizens, concerned about water quality in Como Lake, petitioned the Minnesota Board of Water and Soil Resources to create CRWD. Some of the founding members are still active in the organization today on the Community Advisory Committee. This is a testament to how much residents care about our local water resources.

CRWD hosted a virtual celebration to honor the contributions of residents, community organizations and businesses as well as Board managers, CAC members and staff at the 2020 Recognition and Awards Ceremony.

1

Watershed Citizen of the Year Christina Kunz for sharing her passion for landscaping for water quality with neighbors, friends, and residents as a Minnesota Water Steward.

“As Minnesota Water Stewards, we’re on the front lines of changing the city landscape by working on rain gardens, French drains, rain barrels, pollinator gardens, sidewalk salt reduction, and lawn sprinkler reduction, thanks to training from the Freshwater Society and Capitol Region Watershed District. But the real fun is collaborating with homeowners, fellow Water Stewards, the folks at CRWD, related organizations like Wild Ones, and other watershed districts around the Metro. This volunteer opportunity is the perfect melding of my love for gardening, my undergrad biology degree, my fondness for group projects, and my commitment to the environment.”

– Christina Kunz, CRWD Resident & Minnesota Water Steward

2

Watershed Outreach Program of the Year Saint Paul Parks and Recreation’s BIPOC Parks Ambassadors Program for connecting Black, Indigenous and People of Color to water and the natural world in ways that are meaningful, accessible, sustainable and empowering.

“In order to be a steward of the environment, you have to have a connection to it. And in order to have connection to it, you have to know you are safe when you are there. Our BIPOC Parks Ambassadors program

Watershed Partner of the Year The City of Lauderdale for their leadership and dedication to build clean water projects that benefit residents, wildlife, and the Mississippi River.

“Without CRWD’s persistence, the Seminary Pond project would not have gotten off the ground. CRWD wrangled partners and financial resources to complete a project that removes 2.26 tons of sediment and 10.3 pounds of phosphorus from the Mississippi River annually. CRWD’s leadership encouraged all of the partners (Lauderdale, Falcon Heights, Ramsey County, and the University of Minnesota) to think beyond our borders to make meaningful progress towards cleaner lakes and streams.”

OUR WORK CRWD Water Resources All the water in CRWD eventually drains to the Mississippi River through a complex series of underground stormwater pipes. The District includes five lakes: Como Lake, Crosby Lake, Little Crosby Lake and Loeb Lake in Saint Paul, and Lake McCarrons in Roseville. These lakes serve important recreational needs for CRWD residents and visitors, including fishing, boating, and swimming.

CRWD conducts water quality monitoring of District lakes in collaboration with Ramsey County Public Works,

Como Lake Located in the City of Saint Paul, Como Lake is a relatively shallow (approximately 16 feet deep), 70.5-acre lake located in a highly urbanized watershed. Como Lake and its associated parkland are a major regional recreational amenity within the metro area. The lake drains 1,711 acres of land in Saint Paul, Roseville, and Falcon Heights.

Groundwater is the water found below ground in the cracks and spaces in soil, sand, and rock. In Ramsey County it is used for heating and cooling as well as manufacturing processes. Occasionally Saint Paul Regional Water Services also augments water from the Mississippi River with treated groundwater to meet drinking water demands.

Only a few natural wetlands remain in the District because they were filled or altered during urbanization and development over the past century. Today, the largest wetland tracts include: Woodview Marsh located near Larpenteur Avenue in Roseville, Willow Reserve located near Maryland Avenue in Saint Paul and Villa Park wetland located northwest of Lake McCarrons in Roseville.

Como Lake does not meet water quality standards for nutrients and is therefore listed as an impaired water body by the Minnesota Pollution Control Agency. However, following the alum treatment Como Lake nearly met the state standard for phosphorus in 2020 for the first time on record.

CRWD developed a new management plan for Como Lake that was adopted in May of 2019 to guide future management decisions. This plan focuses on adaptive management of both external (projects outside of the lake that affect what enters the lake) and internal (projects inside the lake that focus on plants/animals/

Trout Brook Storm Sewer Interceptor CRWD owns, operates, and maintains the Trout Brook Interceptor (TBI), which receives runoff from the Cities of Saint Paul, Roseville, Falcon Heights, and Maplewood as well as Ramsey County and the Minnesota Department of Transportation. The system was constructed between the 1880s and 1950s and served as a combined sanitary and storm sewer system. TBI ranges from 5 to 11 feet in diameter and tunnel shapes include circular, rectangular and horseshoe. The systems were separated in 1988. Today, TBI carries rainwater and snowmelt from city streets, parking lots and other hard surfaces to the Mississippi River.

In 2020, CRWD began designing repairs for over 2,000 linear feet of tunnel, which is generally in fair to poor condition. Typical defects in the tunnel include exposed surface reinforcement, cracks and fractures and sediment build up. It is anticipated that design will wrap up in spring 2021 and construction of repairs will occur in fall 2021/winter 2022.

Minnesota Water Stewards CRWD completed its fifth year of the Minnesota Water Stewards program in partnership with Freshwater.

In 2020 the name of the program was changed to from Master Water Stewards to Minnesota Water Stewards based on feedback from partners and program participants in an effort to align with anti-racist values.

As of 2020, 342 residents have partnered with watershed districts, management organizations and cities throughout the Twin Cities Metropolitan Area to participate in this training program. CRWD sponsored five new Stewards and continued to support 14 individuals who have completed the certification and live within the District. Training courses for the 2020 class concluded in April. After finishing the training curriculum, Stewards began their Capstone Projects.

Projects included two residential rain gardens. The graduated stewards reported over 180 hours of volunteer services that included tabling and education at various community events or farmers markets and water related

OUR WORK CRWD Grant Programs Stewardship Grants CRWD values collaboration with individuals and organizations. We view the involvement of all residents as important to improving water resources in the District. Through the District’s grant programs, we hope to encourage a strong ethic of water resource stewardship among residents.

In 2020, 23 grants totaling $154,962 were awarded through the Stewardship Grant program for projects throughout CRWD. Projects included rain gardens, permeable pavement, boulevard curb-cut gardens and an underground infiltration system.

Monitoring locations Of the 16 major subwatersheds in CRWD (see map below), seven are currently monitored for water quantity and quality (St. Anthony Park, Hidden Falls, East Kittsondale, Phalen Creek, Trout Brook, McCarrons and Como). Within the monitored subwatersheds, CRWD collected water quality and quantity data at 22 monitoring sites in 2020.

At nine of these stations, samples were collected during baseflow and stormflow periods. Samples were only collected during stormflow periods at the remaining six stations, as these do not contain any baseflow. Water quality samples from all monitoring stations were

CRWD monitored 11 District wetlands in 2020 for plants.

Previously, the plant and macroinvertebrate data collected was used to determine an Index of Biological Integrity (IBI) for each wetland, which evaluates and indicates general wetland health on a numerical scale based on other large depressional wetlands in Minnesota. In 2015, CRWD began monitoring only aquatic plants in order to use the Floristic Quality Assessment (FQA) method of monitoring and assessing District wetlands. The FQA was developed by the Minnesota Pollution Control Agency in 2012 and is currently used as the agency’s main wetland monitoring and assessment approach.

2020 Climatological Summary The 2020 calendar year was below average in the Twin Cities, with 21.99 inches of precipitation recorded in CRWD. This was 8.62 inches below the 30-year average. The most intense rainfall period of 2020 occurred from May 16 to May 17. Rainfall occurring in this time period contributed approximately 13% of the yearly total with 2.5 inches, including the highest rainfall amount in one day with 2.16 inches on May 17. Overall, the winter of 2019-2020 (November 1, 2019-March 31, 2020) recorded far below normal snowfall. The snowfall total was 23.9 inches; 30.5 inches lower than the 30-year average of 54.4 inches.

There was a consistent snowpack from late November through early March, and area lakes exhibited average ice-off timeframes, which occurred around April 6.

Lakes Results Summary In 2020, water quality varied in each of CRWD’s five lakes. Como Lake has never met the eutrophication standard for total phosphorus, rarely met the standard for chlorophyll-a, but generally met

CRWD staff install Sonde continuous monitoring buoys at Como Lake.

the standard for Secchi disk depth for the history of monitoring. While it again did not meet the standards for total phosphorus or chlorophyll-a in 2020, Como Lake showed immense improvement in these two measures as a result of management actions conducted in 2020 to improve water quality.

Crosby Lake and Little Crosby Lake did not meet the state standard for total phosphorus in 2020, but met the standards for chlorophyll-a and Secchi disk depth. Both lakes have generally not met the total phosphorus standard in recent years, but historically have met the standards for chlorophyll-a and Secchi disk depth. Poorer water quality in these lakes can occur as a result of extensive river flooding in the spring and early summer. Loeb Lake and Lake McCarrons met all eutrophication standards in 2020. Loeb Lake has met the standards for its entire monitoring history, and Lake McCarrons has met the standards since an alum treatment occurred in the lake in 2004.

Four types of green infrastructure practices were constructed from 2010 to 2013 along University Avenue: an integrated tree trench system, rain gardens, stormwater planters and infiltration trenches. These practices incorporate natural landscape features and hydrologic processes to treat stormwater by allowing it to soak into the ground. They also integrate with the

In 2020, staff finalized a report that analyzed data from 2014-2018 at a subset of the BMPs, the side street rain gardens and stormwater planters, to determine their effectiveness and compare to modeled volume and load reductions. This analysis showed that these practices are capturing a greater percentage of storms and a larger total runoff volume than the modeled data predicted. It also showed that the practices remove less total phosphorus (TP),2.3 lbs. on average annually, and more total suspended solids (TSS), 1,913 lbs. on average annually, than the predicted data. This is due to the differences in the TP/TSS concentrations being

OUR WORK BMP Maintenance and Monitoring (cont.) used in the modeled calculations, and points to the importance of collecting on-the-ground monitoring data to give a more accurate representation of load removal by these ultra-urban BMPs. CRWD conducts monthly inspections to ensure that the BMPs are functioning as designed. Maintenance of the fourteen rain gardens and stormwater planters is performed bi-monthly by a private contractor.

Trash and sediment removal along the Green Line are common maintenance needs. Trash is listed as a concern in over 60% of inspections, and sediment is a concern over 50% of the time. More than 20% of the plants in the rain gardens and stormwater planters have required replacement, likely because the highly urbanized landscape lends to warmer runoff temperatures and higher pollutant loads than many plants can withstand. More details regarding the inspections and maintenance of the Green Line are available in the 2019 Green Line BMPs Inspection and

Maintenance Analysis Report.

Highland Ravine Highland Ravine is a 50-acre woodland bluff area that rises from Lexington Avenue up to Edgecumbe Road with residential properties at its top and base and City of Saint Paul parkland to the south. While the bluff is a naturally steep slope, it has been incised with gullies over time because of natural groundwater springs and stormwater runoff. In recent years groundwater springs have been a constant source of water flowing nearly year-round. In response to concerns raised by citizens, CRWD completed a slope stabilization and restoration project in 2014. The stabilization practices constructed included rock grade control structures to slow down runoff, brush bundles for stabilizing the side slopes and a stormwater pond in the north ravine to detain runoff and allow sediment to settle out before runoff discharges to the local storm sewer system.

Maintenance of the Highland Ravine stabilization project is performed by a private contractor. The maintenance crews focus on stabilizing the ravine through invasive species removal and native vegetation establishment. CRWD inspects the ravine regularly to ensure that restoration goals are being met.

30

In 2020, maintenance efforts included the removal of unwanted woody vegetation and invasive species management of garlic mustard, Japanese knotweed, burdock, and reed canary grass. Additional work included removing fallen trees from the channel and repairing a broken outlet pipe. 72 native sedge plugs were also planted in Ravine 1A to help stabilize the steep slope.

CRWD Office BMPs CRWD moved to a new office location in 2018. The new office property includes two adjacent parcels in a residential area of the Midway neighborhood in Saint Paul. Both parcels are outfitted with several BMPs which provide the dual purpose of improving water quality and serving as a demonstration site for visitors and residents. The BMPs onsite include three large rain gardens, a large area of native plantings (both seeded and landscaped), tree trenches, an underground infiltration system, pervious pavers, and a rainwater capture and reuse system that is used to flush toilets and feed a small pond feature. Collectively, these BMPS capture and clean 100% of runoff leaving the site.

In 2020, a private contractor was hired to perform routine maintenance of the various BMPs onsite.

Maintenance activities included weed control of the native plantings, trash cleanup, and cleaning of the catch basins.

Stewardship Grants Hundreds of BMPs have been installed throughout CRWD as a result of the Stewardship Grant program.

Each project owner is responsible for the maintenance of their own respective BMPs. CRWD conducts annual inspections of projects that have been completed in the past five years to ensure maintenance agreements are being upheld and provides feedback and technical assistance to grant recipients. In 2020, CRWD inspected 333 Stewardship Grant BMPs. 92% of these BMPs received an “A” or “B” rating, meaning that no or few improvements were needed to meet BMP design performance. The most common maintenance needs for Stewardship Grant BMPs were weed removal and inlet cleanout.
