Glenn Rehbein Companies 8651 Naples St. NE Blaine, MN 55449 Re: Spirit Hills Development, Lino Lakes, MN Dear William: Thanks for this opportunity to work with you. This letter presents Polaris Group's analysis of the hydrology of the proposed Spirit Hills Development. The analysis is based on our discussions with you, the grading plans we received from you. on March 8th, our discussions with the staff of Rice Creek Watershed District and a site visit. We have attached a general location map and a reduced version of the development plan (Figures 1 and 2). The District staff indicated the following primary issues to address in the development plans: • Rate Control - maintain discharge from the development to pre - development rates for 1 -year and 100 -year events. • Water Quality - provide dead storage for runoff from 2.5" storm. • Volume Control - provide infiltration basins to infiltrate runoff from roadways during a 0.34inch rain event. • Flood Level Control - maintain 1st floor/basement levels of homes 2 -feet above 100-year level in wetland/ponds, and 1 -foot above emergency overflow elevation. • Floodplain - compensate for floodplain fill (100 year level in Rice Lake 886.0) There are three primary watersheds on site .(See Figure 3). Most of the property is a soybean field that is now fallow.. A small portion to the north is wooded and approximately 6.4 acres of drainage comes from the existing residential area to the east. The two wetlands on site are also shown on the map. The soil investigation results show sandy soils typical of the Anoka sand plain. Type B soils were selected for the hydrologic analysis. The standard SCS methods of the HydroCAD model were used to model the runoff. Curve numbers were selected from the attached chart (Chart 1).- Model results are attached. Proposed changes to the existing watershed are shown on Figure 4. The proposed condition model assumes all fallow area is converted to 1/3 -acre residential area. Based on the curve • Mr. William A. T. McCully, P.E. March 10, 2001 Page 2 numbers from Chart 1, post - development conditions will result in less runoff than the existing conditions. Model results are attached. Water quality basins were added to the development plans to treat runoff from the site. These basins are designed to be dry in between storm events and contain the runoff from a 2.5 -inch rainfall. Locations of these basins are shown in Figure 4. These basins also act to control volume runoff from roadways as required. A District Infiltration Worksheet is attached. The interior wetland on site has an open channel outlet with an invert elevation of 889.2. The existing conditions 100 -year flood level is modeled to be 890.1. The proposed outlet of this wetland is a 15 -foot wide broad crested weir at elevation 890.2 with a 4 -foot wide notch 1- foot deep cut in the middle to elevation 889.2. The effective outlet elevation will match the existing outlet elevation (889.2). The top of the weir will act as the emergency overflow. The post- development 100 year flood level is modeled to be 890.2. Basement elevations of the homes around the wetland will have to be set at or above 892.2 according to the above regulations. A 36 -inch equivalent diameter concrete arch pipe with an invert elevation of 888.7 is proposed under the roadway downstream of the weir. The capacity of this pipe with a headwater at 890.2 exceeds that of the upstream weir and will not control the level within the wetland under normal conditions. We checked extreme flood conditions by modeling the effect of blocking more than 80 percent of the culvert during a 10 -inch rainfall. The results show that the water elevation within the wetland did not exceed the minimum basement elevations recommended above. We noted a small (7200 sq.ft.) portion of floodplain fill at the northwestern part of the site. We recommend compensating for this fill by an equivalent area of excavation on the southwestern part of the site. Please review the information we have provided. If you have questions or need further information please contact me (952) 881 -3050. Thank you.

ENVIRONMENTAL BOARD COMMENTS: The following is a summary of the comments made by the • Environmental Board Members, Here are our assignments for the next board meeting: Amy — Vegetation; Lighting Connie — Impervious Surfaces; Ground Cover 17apx6 &_Pe %peartov_Boapb Xtrt_oq A1vo Aaicca 1 Dave —Tree Preservation; Vegetation Mike — Stormwater Infiltration and Treatment; Lighting Rod — Impervious Surfaces; Buffers Scott —Tree Preservation; Stormwater Infiltration and Treatment Tere —Soil Treatment; Buffers What I intend to do is to go through this list for each project. I'll ask if there are any additional recommendations or questions regarding TREE PRESERVATION. Once we've dealt with that I'll move on to BUFFERS and so on. If you have specific recommendations that you can write out in advance of the meeting that would move things along even more quickly and efficiently. To prepare for our new roles, I encourage all of you to follow Dave's advice and take it upon yourself to learn more about the topics for which you have volunteered. Here is my attempt to summarize the goals that we discussed. You'll note that I eliminated WEB SITE as a goal and instead made it one of the potential activities that fall within GOAL #2. I welcome your feedback and editorial comments. GOAL #1. Educate developers about the benefits of including prairie gardens in their landscape designs. Potential Activity — Provide developers with the opportunity to see examples of blooming prairie gardens and to talk with the people who "maintain" them. GOAL #2. Increase citizen understanding and appreciation Lino Lakes' unique environmental qualities. Potential Activities — create a web site Pilot Restoration Project Update Environmental Board Packet Encourage landscaping companies to advertise in city Investigate possibility of using the "City Wagon" GOAL #3. Identify and pursue preservation of, unique environmental assets of the city. Potential Activity -- Promote the preservation of the property located on the north side of Lino Lakes Elementary. GOAL #4. Restructure monthly meetings to preserve 50% (one hour) of the meeting to advance our proactive goals. Potential Activity —assign responsibilities (e.g., tree preservation, buffers) to individual board members 17apico_ &_Pexpeariov_BoapS Xin oq Aavo Aa ceo- 2 • • • GOAL #5. Increase communication with analogous units in other metro -area cities to avoid "re- inventing the wheel" and to look for collaborative opportunities. Potential Activity — develop a list of cities that have groups focused on the environment Host a social event that brings these groups together to share ideas, goals, and experiences. GOAL #6. Investigate and promote the possibility of developing a conservation development ordinance for the city. Potential Activity —get examples of such ordinances from other cities. GOAL #7. Develop and implement a strategy to obtain more resources (staff and financial) to enable the city to establish itself as the leader in the metro area in terms of development that is both economically and environmentally intelligent. GOAL #8. Communicate more regularly, and more directly, with City Council. Once we've reached agreement about the wording of these goals, I would like to request time at one of the City Council meetings to present these goals and to ask the Council if they have any goals that they would like us to pursue. Finally, Marty could you make certain that you include a copy of the Developer's Guidelines that the Board wrote, with the next meeting packet?

ENVIRONMENTAL Coordinator Date • 17apxQ &_Pezpearsov_Boap8 Xui_oO Aivo Aaicsv • ENVIRONMENTAL BOARD • • 2000 GOALS 1. Work with City staff and consultants to complete the Natural Resources Inventory and management plan process. Work with Council, staff and other boards to disseminate this information to the community and educate the community about its application and importance. Identify potential areas of controversy and discuss these with City staff, City Council, and stakeholders as needed. The intent of these discussions is to translate the recommendations in our Environmental Planning Handbook into a workable policy that is reflected in our City ordinances. 2. Utilize data in the ecological inventory to formulate a recommendation for a "green infrastructure" in the City. The product would attempt to incorporate the City's lakes, wetlands, and other high - quality areas into a continuous network of open spaces that, would preserve the ecological health of these areas and maintain vital wildlife corridors. This proposal is intended to be a starting point for future discussions with all interested parties that should eventually result in the adoption of an open space plan for the City. 3. Prepare a set of standard recommendations on the environmental issues that are common to all development projects, and discuss these recommendations with City staff. Issues to be considered might include lighting, use of native vegetation, buffers, stormwater management, impervious surface, soil treatments, tree preservation, and open space issues. 4. In collaboration with City staff, devise a standard form for use by the Environmental Board to evaluate development projects. The form should incorporate the issues identified in goal number three (above). The intent of this form is to clearly communicate our priorities to developers, streamline our evaluation procedures, and to provide a format for clear communication with staff, P & Z and Council. 5. Encourage City Council and City staff to continue the process of educating developers on "conservation development" issues. Participate in discussions aimed at establishing standards and guidelines related to environmental issues. Encourage council and staff to hold periodic Developers Forums to communicate with developers and convey information about City objectives including environmental objectives. 6. Identify at least one environmental restoration project that requires participation of nearby residents and begin planning the project. This will require recruiting and education citizen volunteers and pursuing funding. The intent is to increase citizen ownership of the City's environmental vision and to provide a demonstration of the appeal of effective environmental practices. 7. Seek opportunities for continued education of the Environmental Board. 8. Continue efforts aimed at public education and awareness on environmental issues. Update and revise citizen packets. Encourage participation by schools and private landowners in wildlife habitat programs. Educate residents on issues of good land stewardship. AGENDA ITEM 7E STAFF ORIGINATOR: Marty Asleson MEETING DATE: March 26, 2001 TOPIC: Conservation Partners Grant/Buckthorn Control BACKGROUND: The Purpose of the Conservation Partners Grant Program is to encourage the enhancement of fish, wildlife, and native plant habitats and research and surveys of fish and wildlife directly related to specific habitat improvement projects through cooperation by private organizations and local governments. The grant program funds a maximum of 50% of the total eligible project costs not to exceed a maximum grant of $20,000. Applications are due by March 31, 2001. The City of Lino Lakes Conservation Partners Grant Program submittal is intended to restore a woodland in the Birchwood Acres neighborhood area by removing existing buckthorn from the understory. City maintenance staff and neighborhood volunteers will perform this work. The grant is also intended to initiate a 3 to 5 year volunteer education and maintenance "follow -up ", with the residents in Birchwood Acres and the Clearwater Creek areas. Residents will be encouraged to volunteer for removal of buckthorn on private property and be given opportunities for a common chipping schedule. Clearwater Creek is presently under an initial invasive plant removal program funded through the Conservation Development Management Plan Agreement. The grant request to The Minnesota Department of Natural Resources is for $8197.97. The City portion of the grant is $4098.98, of which $2,203.69 is a soft match of our labor hours and equipment costs. The rest of the monies would be to purchase the necessary chemicals for invasive removal, provide for an updated Environmental Board education packet to be distributed to residents involved, and a contingency of $1500 for ground story replacement plants should a sufficient seed bank be unavailable. OPTIONS: 1. Approve the Minnesota Department of Natural Resources Grant Application submittal and adopt Resolution 01-48, A Resolution To Support 2001 Minnesota Department Of Natural Resources Conservation Partners Grant For Buckthorn Control. 2. Do not approve the Grant. RECOMMENDATION: Option 1. • Council Member introduced the following resolution and moved its adoption: • CITY OF LINO LAKES RESOLUTION NO. 01 - 48 RESOLUTION TO SUPPORT 2001 MINNESOTA DEPARTMENT OF NATURAL RESOURCES CONSERVATION PARTNERS GRANT FOR BUCKTHORN CONTROL WHEREAS, The City of Lino Lakes regards the natural resources within the City as an asset and worthy of management; AND WHEREAS, The City of Lino Lakes has invested in and developed an Environmental Inventory and Management Plan to guide the City in efforts to preserve and conserve the natural resources within the City; AND WHEREAS, The City of Lino Lakes has moved to cooperate with the Department of Natural Resources in the Wild Land Urban Interface Program to reclassify our existing resource inventory to the Minnesota Land Cover Classification System, and to expand on, and help guide our initiatives outlined in the Lino Lakes Resource Management Plan; AND WHEREAS, One of the goals outlined in The Lino Lakes Resource Management Plan is to implement an invasive plant management program, and to educate and involve residents in these efforts; AND WHEREAS, The Conservation Partners Grant Program will help in these efforts to implement an initial invasive plant management and education program; NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF LINO LAKES, MINNESOTA: 1. That the City of Lino Lakes wishes to enter into agreement with the Minnesota Department of Natural Resources under the Conservation Partners Grant Program to implement a Buckthorn control, neighborhood involvement and education program in the Birchwood Acres and Clearwater Creek Areas. 2. That the City of Lino Lakes will budget $4098.98 to match a Minnesota Department of Natural Resources dollar amount of $8197.97 total grant cost, and of this $4098.98, $2203.69 would be provided in the form of "in- kind" contribution. Adopted by the Lino Lakes City Council this 26th Day of March, 2001. John J. Bergeson, Mayor Ry -Chel Gaustad, CMC City Clerk The motion for adoption of the foregoing resolution was duly seconded by Council Member and upon vote being taken thereon, the following voted in favor thereof: The following voted against same: Whereupon said resolution was duly passed and adopted. CERTIFICATION I hereby certify that the above is a correct copy of a resolution duly passed, adopted and approved by the City Council on date. • Ry -Chet Gaustead, CMC City Clerk • • ENVIRONMENTAL BOARD GUIDELINES The following guidelines were formulated by the Environmental Board. We suggest that these guidelines be distributed to developers who intend to initiate projects in Lino Lakes. By providing these guidelines, the Environmental Board hopes to assist developers to create a vision for their projects that is consistent with the environmental ethic of the City of Lino Lakes. Tree Preservation Trees are among the most visible components of the City's environmental landscape. Therefore, developers should make every effort to preserve them. Where trees must be removed, new trees should be planted on site, on an inch - for -inch diameter replacement basis. Before a development project can be scheduled for review by the Environmental Board, a tree inventory and preservation plan must be completed by the developer. Stormwater Infiltration and Treatment Given the extensive wetlands that are found in Lino Lakes, careful management of stormwater is essential. Therefore, project design should attempt to maintain on -site infiltration at pre - construction levels by maximizing infiltration of stormwater on the site and to reduce runoff into lakes and naturally occurring wetlands. When runoff into water bodies is unavoidable, stormwater should be directed over a vegetated surface via broad swales. The design should attempt to maximize the surface area over which the water flows. The total linear distance of this stormwater treatment train shall be at least 100 feet between the stormwater detention pond and the destination (ditch, lake, wetland). Environmental Context The City's environmental resources are distributed in a manner that is independent of property boundaries. Therefore, planning of open spaces and other environmental aspects of the project must consider the larger ecological context of the project's location within Lino Lakes generally, and within the greenway system specifically. Environmentally sensitive areas in close proximity to the project site should be identified from the City's ecological delineation map. Project design must attempt to use the buffers and open spaces (elements included in all projects) to establish corridors that will allow the open space network within a project to be connected to nearby open spaces of significant size. Impervious Surfaces One of the easiest ways to minimize the negative impact of development on our environmental resources and services upon which we depend, is to be conservative in the construction of impervious surfaces. Therefore, developers should be aggressive in their efforts to minimize the impervious surfaces in any development. For example, alternatives to asphalt and concrete parking areas should be considered. Similarly, where possible, developers should work with city staff to use narrower streets in their development projects. Soil Treatments Most development projects require that soil be thoroughly compacted to produce the pad on which structures are placed. Unfortunately, this policy is completely at odds with proper preparation for the landscaping that will follow. The inevitable result is reduced on -site infiltration, excessive watering of landscaping, and increased herbicide -laden runoff into wetlands. Therefore, after construction has been completed and top soil has been spread, the soil should be tilled to a depth of 8 -10 inches. Ground Cover Environmentally sound landscaping calls for the use of native plants that do not require irrigation or the addition of nutrients. Therefore, the use of sod should be minimized as much as possible. Excessive use of water and the introduction of excessive fertilizers into our wetlands are not the only disadvantages of sod. In addition, this form of groundcover results in a tremendous yard -waste problem and added air pollution resulting from constant lawn maintenance. Vegetation The most effective approach to landscaping is one that uses our native plants that are adapted to this climate and which support our fauna. Significant stands of native vegetation within the project area should be identified and efforts made to preserve them. When restoring vegetation, we recommend use of native materials or other plants that require little irrigation or nutrient addition. Use of exotic, invasive species is strongly discouraged (eg., European Buckthorn, Norway Maple). See City Environmental Coordinator for lists of recommended and non - recommended species. Buffers Buffers, consistent with the City's Conservation Development Handbook, are a mandatory element for all developments and should be site - specific. They should be placed around all ecologically sensitive areas such as wetlands, prairie remnants, significant wildlife habitats, or high quality woodlands. These buffers may consist of undisturbed vegetation, restored prairies, trees, shrubs, or other plant materials consistent with the Vegetation guidelines above. Lighting All outdoor lighting should be both energy efficient and environmentally friendly. The citizens of Lino Lakes enjoy the night sky and the animals that fly through it. High intensity lighting or lighting that is allowed to scatter over a large area, diminishes the ability to view these amenities. Therefore, lighting shall be low - impact, low in stature, downwardly focussed, and no spill.
