Main Street Village Concept Plan – Azure Properties – PUD Mr. Asleson presented his staff report to the board. This item has been previously submitted for review. There were issues the developer needed to address before the environmental board could move forward with this project. The issues have since been addressed. Mr. Asleson first reviewed the background information on this Item. He then reviewed the analysis, SWPPP, unique resources, tree preservation, AUAR, landscaping and recommendations. Mr. Asleson commented that their AUAR calculations look reasonable at this time. He stated that Rice Creek Watershed District has issued a conditional approval. It was recommended by the board that Mr. Asleson write a letter to the City of Lino Lakes Engineer addressing the changes being made to the SWPPP. The following are the changes/additions made to the SWPPP: 1. Page 4 of the Main Street Village SWPPP, the words “and city” should be added after the bullet point that states “any dewatering discharge shall be approved per the local LGU requirements. 2. Temporary storm ponds should located on the plan sheets 3. A method of dewatering turbid storm water from temporary storm ponds should be detailed on the plan sheets and approved by the city. 4. Location of the SWPPP and weekly, post rain all event inspection sheets must be located on site and indicated on the plan. 5. All infiltration areas must be protected from compaction and sequenced correctly in order to protect the integrity of the stormwater feature. Protection devices (fences) and sequence dialog must be shown on the plans. 6. Location of a clean out area for concrete trucks must be indicated on the plans and clearly signed in the field. The following changes/recommendations are made by the Environmental Board as of November 28th, 2007: 1. All stormwater volume and flow designs must be evaluated for conformance to RCWD and AUAR standards. 2. Site access for surface water treatment areas must be shown on the map. 3. Slopes of wetland mitigation areas be changed to conform to the AUAR. 4. Recommend 1-2 inch scraping the wetland soils in the freeze/thaw situation to control reed canary grass. Also recommend the scraped soils in wetland fill areas be salvaged and stockpiled for use in the wetland mitigation area. 2 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 5. In general, there should be a narrative to the Boards and the City Council addressing all of the mitigation strategies presented in the AUAR that effect this development. 6. All infiltration areas and wetland mitigation areas should be seeded with the city native seed mix. The city transitional mix is shown on the plan and this is a good mix between cultural areas and wetland/pond areas. The BWSR U8 mix is shown on the wetland mitigation slopes. A better mix selection from the BWSR choices would be the WI mix. However, we recommend the city native pond seed mix for this area, supplemented with flowering native plugs every 10 feet. All biofiltration areas should also be supplemented with flowering plugs. Biofiltration areas planted with the transitional seed mix should have a low-profile height associated with the forbes. All native seed mix areas should be planted by a contractor on the Minnesota Department of Natural Resources list of contractors. The native areas should be maintained for a minimum of 3 years by the approved contractor and if possible burned at the end of 3 years. 7. More trees should be planted particularly in type C and D soils. The C type soils intersect biofiltration pond number 9 and wetland mitigation area 10 on the north side, east side, south side and south west corner. Salix ‘Golden Curls’ is a marginally hardy plant and non-native. The AUAR recommends that water infiltration areas be augmented with large herbaceous woody plant materials such as Aspen and Cottonwoods. Therefore substituting more of these types of species and more abundantly in the type C soil areas is in accordance with the AUAR recommendations. Cottonwoods must be of the non-seeding types. Recommend one tree per 25’ O.C. in these type C soil areas. 8. Side slope of the wetland mitigation area be no steeper than 6:1 horizontal to vertical. 9. Site access for maintenance reasons must be shown on the plan for stormwater treatment areas. 10. A letter be written to the City Engineer adding issues to the project Storm Water Pollution Prevention Plan 11. Keep parking stalls down to the minimum allowed by zoning code. Add pervious paving if additional parking stalls are necessary. 12. Lighting should not exceed the city minimum lighting allowed by city code. Canopy lights of the gas station must be flush mounted bulbs that present no glare issues and downward directed. Monuments should be kept to a minimum and minimize light spill. 13. Request planning staff review trash and recycling accessibility as they relate to truck movements. 14. No soils may be imported or exported to the site without city approval. Soils hauled in should not be substantially different from soils that were input into the stormwater model. 3 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 Motion: Motion was made by Bor, seconded by Andrzejewski to approve the recommendations and forward to Planning & Zoning. B. Vaughan’s First Addition Mr. Asleson stated this item was proposed for platting in 2004. At that time, there was an extensive study (EAW) to look at impacts from proposed development from the north end of Rough Grouse Road to the island in Wards Lake, connected by a bridge. The project was approved at that time. The developer decided not to construct the bridge connection. The landowner (Mr. Vaughan) has proposed developing one lot at the end of Rough Grouse Road. Mr. Asleson presented his staff report. He reviewed site data, natural resources, SWPPP, natural resources inventory, watershed issues, unique resources, landscaping and recommendations. He also reviewed the attachments. Mr. Asleson stated the flood plain does not meet regulations. The developer has an incorrect ordinary high water plan. He stated there is very little room to work on this plan. Ms. O’Dea asked if they have room to build a house. Mr. Asleson stated that the lot area standards may be met if they use both lots. Ms. O’Dea questioned how is the high water verified? Mr. Asleson stated it is the DNR who verifies the high water. The information we have from the developer does not adhere to the DNR’s information. Ms. Bor stated there was not a tree preservation plan included. Number 5 under Mr. Asleson’s recommendations addressed this issue. If the plan comes back again, it will need this information. The Environmental Board has reviewed this item and finds it incomplete at this time and makes the following recommendations: 1. Possibly move the house to be part of outlot A so it meets the shoreland requirements. 2. No importing or exporting of soils. 3. Include a tree preservation plan. Motion to approve recommendations indicating that we found application incomplete and forward to Planning and Zoning Board at this time. Motion by Ms. DeHaven and seconded by Ms. Andrzejewski. Motion carried unanimously. 6. DISCUSSION ITEMS A. Comp Plan Update – 4 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 Mr. Asleson reviewed the Comprehensive Plan Update. He discussed the upcoming open house. Ms. Bor mentioned at this time she is the only member of the Environmental Board who volunteered for the comp plan committee who has been regularly attending meetings. She suggested having another board member attend the comp plan meetings. She suggested that if a member volunteers for a committee outside of the Environmental Board and cannot attend on a regular basis, an alternate or new member should fill the vacancy. She also stated the opportunity to be on the comp plan committe is a great learning experience. It was discussed by Board Members who they will send in place of Kim Brouillet to the CPAP Open House of December 4, 2007. It was decided that Mr. Brown would attend. B. Preliminary goals 2007 – Mr. Asleson stated before our next meeting members should think about new goals for 2008. He also stated he has an upcoming meeting with an Eagle Scout at the middle school on November 29th, which is one of our 2007 goals. He stated we are participating in comp plan process and in the RMP process which is part the comp plan and is currently being worked on. He asked members to bring suggestions, new ideas or changes to our next meeting. C. TMDL Update Barbara Bor Ms. Bor stated that the public needs to be aware of the issues regarding Total Maximum Daily Load (TMDL). State and federal law states the city is going to have to fix pollutant loading issues within the city. The question was raised about who is subject to adhere to these requirements and who are they directing to fix the problems at this point? It was stated that RCWD is our LGU but the city is called an MS4 and has to adhere to TMDL. That is why we are doing a Resource Management Plan. The question was raised concerning the responsibility of the surrounding cities. Mr. Asleson stated they are responsible for meeting their own TMDL requirements. By law other cities will have to meet standards as well. To help expedite the improvement process there are several options suggested to assist with current problems. One option would be a drawdown of area lakes which might include a total fish kill or fish gates. Ms. Bor stated that there will be a public hearing and an opportunity to give input. 7. ADJOURN It was noted that the next meeting of the Environmental Board will be on December 19, 2007. 5 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING JULY 25, 2007 6 DRAFT MINUTES There being no further business, Mr. Brown moved to adjourn at 8:25 p.m. Ms. Bor seconded the motion.
