The plan assists city staff and decision makers in considering impacts from variances and enables development and redevelopment in a systematic, orderly manner while managing water resources. The CWRMP, along with other plans, informs the water resources chapter of the local comprehensive plan. It describes delivery for three core services related to surface water; runoff management, flood control, and clean water. At the City Council’s November 21st work session, staff introduced the draft CWRMP and described the schedule, plan purpose and structure, goals, policy clarifications, and key issues. At their January meeting, City Council approved staff to submit the draft plan for agency review. The plan was reviewed by the Metropolitan Council, Minnehaha Creek Watershed District, and Nine Mile Creek Watershed District for conformity with state statute and watershed district local water management plans. Comment letters from each agency are included with this report as attachments. The purpose of the April 3rd work session is to continue to discuss policies and how they inform implementation of the plan, as well as provide examples of how the plan is being applied to ongoing work in the areas of capital expenditure, development and redevelopment (private and public, commercial and residential), and system operation and maintenance. The draft plan update is nearly complete. Upon final refinements, staff will resubmit the draft plan for final review and approval from the agencies. Once approved by the agencies, staff will ask City Council to adopt the 2018 Comprehensive Water Resources Management Plan. Water resources management is a complex topic. Managing for surface water outcomes is difficult because of incomplete or contradictory knowledge, the number of people and opinions involved, the large economic burden, and the interconnected nature of surface water topics with land use, water utilities, and other topics. Generally, technical issues are viewed as problems to be solved. Given the level of complexity and STAFF REPORT Page 2 our incomplete understanding in water resources, using a problem solving approach can quickly lead to regret, as new information reveals past flaws in the approach. Solving one problem often creates a new one. The community resilience approach to water resource management takes more holistic but incremental steps to make key water targets, and their related issues incrementally better over a broad range of activities. Incremental changes over time get us closer to the goal of a resilient and vibrant community with regard to flooding and clean water. The draft 2018 CWRMP aims to move us in the right direction. The provision of the three core services (runoff management, flood control, and clean water) take place using two primary strategies, the lifecycle delivery of physical infrastructure, and programmatic activities. These strategies are outlined in the implementation program (section 15) and supported by the plan policies (section 3). Pathways for physical infrastructure implementation include the Capital Improvement Planning process where improvements such as street and park projects are already planned or as standalone flood protection or clean water projects. The ongoing operation and maintenance of this infrastructure is important for retaining the value of the investment into the future. Programmatic approaches to water resources management include land use controls and permitting (such as elevating structures, stormwater management guidance, and erosion and sediment control), data sharing (water resources map and online resources), sanitary inflow and infiltration mitigation, pollution prevention (including street sweeping), wellhead protection, and more. The implementation program includes a Flood Risk Reduction Strategy and a Clean Water Strategy. As these strategies are developed, the outcome will be a priority approach to infrastructure and programmatic strategies that defines service targets, short and long-term goals, and a menu of management practices with the highest probability of making surface water outcomes incrementally better, at the least cost. The Flood Risk Reduction Strategy (FRRS) and Clean Water Strategy (CWS) scopes have yet to be written and the outcomes are fluid at this point; however, the deliverables for each could include investigation of specific geographies within the community where a combination of infrastructure and programmatic activities could be applied. This could focus on geographies where there are opportunities (maintenance, capital improvements, or private development and redevelopment is already happening) and/or priority issues. Strategies could include policy reviews, community consensus building, and/or area-specific plans. Whereas the CWRMP provides high level planning, the FRRS and CWS would provide more detail. The benefit of these strategy plans is that activities are reviewed at the neighborhood or community scale instead of only a narrow street-by-street or project-by-project scale. It allows for better coordination among various programs (including street reconstructions, sanitary inflow and infiltration mitigation, infrastructure maintenance, pollution prevention, and others) while looking beyond project areas to determine if benefits or risks may be realized beyond project boundaries. 1 March 19, 2018 Th e fo l l o w i n g is a su m m a r y of th e Mi n n e h a h a Cr e e k Wa t e r s h e d Di s t r i c t ’ s re v i e w of th e Ci t y of Ed i n a Dr a f t Lo c a l Wa t e r Ma n a g e m e n t Plan dated De c e m b e r 20 1 7 fo r co m p l i a n c e wi t h MN Ru l e 84 1 0 . 0 1 6 0 , MN St a t u t e s §10 3 B . 2 3 5 , an d th e MC W D Wa t e r s h e d Ma n a g e m e n t Plan.

I:\Building\SafetyPoliciesInformation\EdinaExtrasServer\PDF's\WEBSITE SD11 STORMWATER.pdf Purpose: To provide guidance for the preparation of site plans consistent with City of Edina ordinance. Guidance: Stormwater precautions can be described on a grading plan, site plan, and any other plan that describes the work. For category 2 permits, a specific stormwater plan is required; this plan can be combined with an erosion control plan when required. City code reference for these standards and precautions can be found in 10-110,111, 10- 341 to 10-345, and 10-674 to 10-710. Stormwater precautions and/or the stormwater management plan serve to accomplish the following (Definitions for words in bold can be found on page 2): •Limit the changing of drainage areas and properly control or divert flow when areas are changed. •Limit and manage the risk associated with the creation of new concentrations of drainage. •Protect and maintain existing flow paths and/or plan new flow paths that do not increase risk to neighboring property. •Control and reduce the amount of runoff directed to landlocked areas, and areas that drain to known issues of structural flooding. •Apply precautions or facilities to mitigate volume and rate of flow from sites proposing additional impervious surface. Scope: The following permitted construction activities require stormwater precautions consistent with this policy: Category 1 – Construction activities that include the demolition, remodel/addition, accessorial structure, landscaping/retaining walls or a new pool associated with a single/double dwelling that: o Disturb more than 2,500 square feet of soil. o Exceed more than ten cubic yards of cut or fill. Category 2 - Any of the following permitted activities associated with a single/double dwelling unit: o Construction of a new dwelling unit. o Work determined by the City Engineer to present risk to neighboring private properties, public infrastructure or waterways/wetlands. o Category 1 work that is proposing any of the following conditions: •A change in grade that significantly affects a drainage area, altering the area of land flowing to an existing drainage path. •The addition of over 600 square feet of new impervious surface in areas that drain to structural flooding issues. •The addition of over 400 square feet of new impervious surface with a drainage path that is directed to private property. •Any fill or addition of impervious surface on sites that drain to landlocked basins. •Fill on a property below the 1% annual chance base flood elevation for local flooding issues. •Fill on a property associated with regional flooding issues. •A site that proposes to modify an active grading permit, or permanent facility. •A site that proposes greater than 50% impervious surface. •The continuation, addition or modification of previously permitted activities from the last two years, that when reviewed as a whole would trigger one or more of the above requirements. EDINA BUILDING SAFETY POLICY/INFORMATION1 Storm Water for Single/Double Dwelling Units subject City Ordinance - code reference Engineering Department department approval SP-003-E policy number 04/25/2017 revision date 06/01/2017 effective date 1 of 2 page number 1.All Building Safety sheets adopted by Fire Department and Inspections Department. 2. Policy -B suffix developed by Inspections Dept. –F, Fire Dept. – E, Engineering Exemptions: Activities with approved development plans associated with a zoning action where stormwater plans already exist and are in force, if the proposed permit does not modify the storm water plan. Requirements (Category 1): The following standard applies to all grading permits: Category 1, minimum standard: o Show or describe existing and proposed grades, areas of exposed soils, and existing and proposed impervious surfaces. Use sketch, notes, and/or narrative. Include spot and relative elevations, flow arrows, or contours. o Accurately depict current and proposed drainage. o Include and perform the following site drainage precautions: •Reduce soil compaction by limiting equipment access to specific construction paths, if applicable. •Loosen compacted soils through raking, tinning, tilling, or other methods to a minimum depth of 2 inches. •Place new, organic rich, topsoil to a minimum depth of 4 inches on areas of disturbance. •Place sod or seed and mulch on exposed soils as soon as practical. Requirements (Category 2): The following applies to work meeting the conditions described in the scope section above, or meets any of the conditions described in category 1 and for grading associated with any of the following: Category 2, higher standard: o Provide and implement a Stormwater Plan that meets minimum requirements. o Follow any special plan requirements. Stormwater Plan requirements: o No increase in peak rate for 10% annual probability event (NOAA Atlas 14, 10-year). o Control of storm water volume to 1.1 inch MIDS standard. o Use of standard permanent controls is encouraged. o Custom designed permanent facilities are used only when permanent controls are considered, but unable to meet peak rate or volume control standards. o Must be prepared and signed by a licensed professional Civil Engineer in the State of Minnesota. Special Plan requirements: For permits associated with landlocked basins, or local, regional flood issues: o No increase in peak flood elevations for 1% annual chance flood event (NOAA Atlas 14, 100-year). Definitions: 1% annual chance base flood elevation is the elevation which has a 1% annual chance of being equaled or exceeded in any given year. Active grading permits are sites with a building permit with associated grading work. Impervious surface is constructed hard surface that either prevents or retards the entry of water into soil. Landlocked areas/basins are areas of the landscape with no natural outflow to downstream surface waters. Local flooding issues are described in the City of Edina Comprehensive Water Resources Management Plan, and available on the water resources interactive map. MIDS is the minimal impact design standard developed by the Minnesota Pollution Control Agency. Permanent controls are simple, durable or standard practices uses to control stormwater flow that require limited ongoing maintenance. Permanent facilities are structural practices that infiltration, detail, divert or filter stormwater and require ongoing maintenance. Regional flooding issues are described by FEMA and available at www.msc.fema.gov. Structural flooding issues are local flooding issues that affect public or private structures.

AT TAC HME N T S: Description Arden Park Update Staff Report Arden Tree Mapping Arden Design and Public Proces s Schedule Fishing Pier Sketch - South of 54th Proposed ADA Landing and Trail - North of 54th DRAFT Landscape Base Plan DRAFT Vegetation Plan PARCS Works Ses s ion Presentation Tuesday, April 3 2018 City Council Ann Kattreh, Parks & Recreation Director Arden Park Update Information / Background: This meeting is a joint work session with the Parks & Recreation Commission (PARC) and City Council. At the March PARC meeting, the commission decided to allocate this meeting to an update on the Arden Park project. Please note that at the current stage of the design phase, between 30 and 60 percent, there will continue to be changes and modifications to the plans presented at the work session and in this packet. Since reporting to the public at an open house and then also the PARC on Jan. 9 and the City Council on Jan. 17 at the 30 percent design phase, the Arden Park design team has been working diligently toward the 60 percent design feedback coming up in May. On Saturday, May 5 staff will hold an open house, weather permitting, at Arden Park. The meeting will move indoors to Edina City Hall in the event of inclement weather. Staff will then report to the PARC on Tuesday, May 8, the City Council on Tuesday, May 15 and the Minnehaha Creek Watershed District Board on Thursday, May 24. At this joint work session staff will present an update on the following: • Stormwater management – information only • Creek alignment and tree removal – information only • Brookview Avenue trail – feedback requested • Ash tree removal – feedback requested • ADA accessible landing north of 54th Street – feedback requested STAFF REPORT Page 2 Tree Removal Update and Ash Trees Based on the current status of pre-60 percent design, 68 of 457 trees will have to be removed for construction. Tree removal during the concept phase of the design was estimated at over 90 trees for the creek remeandering alone. Twenty-four of the 68 trees slated for removal are ash trees. Of the 457 trees within the project scope, 77 are ash trees. Of the 77 ash trees, 47 have a DBH (diameter at breast height) less than 12” and 30 ash trees have a DBH greater than 12”. Of the 24 ash trees proposed to be removed for construction, 7 have a DBH of 12” or greater. City Forester Luther Overholt also recommends injecting 3 trees in the park to prevent Emerald Ash Borer and hopefully save the trees. Of these significant trees, one of the trees is along Minnehaha Boulevard, one is on Brookview Avenue and the other is close to the playground. This project provides a unique opportunity to remove and replace ash trees which will surely die eventually. Emerald Ash Borer has been found in all surrounding communities and it is only a matter of time before it will be identified in Edina. The City Forester would like to remove as many of the ash trees as possible and replace them with much higher quality trees. It will be less expensive, less impactful to new park construction and easier to access many ash tree locations during project construction. While the larger trees with a DBH of greater than 12” have a greater impact to tree canopy, they are also more difficult, costly and dangerous to remove in future years as they die. The ash trees on the north half of the park would definitely be the most difficult and costly to remove in the future. It is recommended to remove at least those during construction. As the project reaches the 60 percent report phase, it will be easier to recommend exact trees for removal. City Forester Luther Overholt will be present at the work session to answer any questions about ash tree removal and tree replacement strategies. Brookview Avenue Trail At the Jan. 9 open house, feedback was given by some residents on Brookview Avenue that they did not support the trail along Brookview Avenue. Neighbors stated that residents walk in the streets and step up on to the curb and grass if a car is approaching. Providing trail loops for walking around parks is a critical element in park master planning and is highly recommended by staff and the consulting team. It provides recreational opportunities, provides links to all parts of the park and, most importantly, safe routes for moving through and around the park. ADA Trail and Landing As the Arden Park team continues to work through the 30 percent design phase to the 60 percent design phase, challenges and opportunities arise. An opportunity that the team felt was worth considering is the addition of an ADA accessible trail from Minnehaha Boulevard down to the creek with an accessible landing just north of 54th Street. A trail and a canoe landing were originally included in the project plan, but after further research it was determined that this trail could be designed to meet ADA accessibility requirements along with the landing deck. This trail and landing create an excellent opportunity for people with mobility challenges, strollers, etc. to get right up to the edge of the creek in addition to the ability of a person with physical limitations to exit the creek at this point. The additional cost for this upgraded amenity was not STAFF REPORT Page 3 available at the time of this report deadline, but the incremental additional cost would be borne by the city and will be presented at the work session. The landing and viewing terrace in the current plan are a MCWD cost. The city would pay only the incremental increase to achieve ADA accessibility. Council and Commission Feedback Requested: Brookview Trail • Do the Parks & Recreation Commission and City Council support the trail along Brookview Avenue as presented in the original Arden Park concept plan? ADA Trail and Landing • Do the Parks & Recreation Commission and City Council support the upgrade of an ADA accessible trail and landing north of 54th Street to be included in the 60 percent design phase of the project? The additional incremental cost of the ADA upgrade would be borne by the city. Ash Trees a) Do the Parks & Recreation Commission and City Council support the removal of at least 50 of the 77 ash trees in the park project area? 24 of the 50 are part of the creek construction. This would remove approximately 94 total trees in the park. These trees would be replaced at a minimum of 1 to 1 with high value trees. This is 21 percent of the tree cover in the project area. OR b) Do the Parks & Recreation Commission and City Council support the removal of all 77 of the ash trees in the park project area? 24 of the 77 are part of the creek construction. This would remove approximately 121 total trees in the park. These trees would be replaced at a minimum of 1 to 1 with high value trees. This is 26 percent of the tree cover in the project area. 52nd Street52ndStreet 53rd Street 54th Street J u a n i t a A v e n u e I n d i a n o l a A v e n u e Arden Avenue K e l l o g g A v e n u e O a k l a w n A v e n u e B r o o k v i e w A v e n u e Park Place M i n n e h a h a B o u l e v a r d ¯0 250Feet Arden Park Restoration Project Proposed Channel Area of Potential Effect Ash Trees > 12 inch DBH Ash Trees < 12 inch DBH Ash Trees inoculated Trees removed for construction Unaffected Trees Notes:1.
