• February 4, 2003 A Best Management plan should be required for development and post development agreement. This plan should address soil and toe protection during development, and site keeping after development. Site keeping after development should include parking area sweeping, Iitter pick-up, storage of any hazardous rnaterials, turf and native -area maintenance plans, and pond maintenance. All topsoil on the site should remain on the site. Any intention to import solis, must have the approval of the City, and be submitted to RCWD for review of surface water infiltration rate changes Livina Waters Lutheran Church: Since 1993 (the time The church was built), the Environmental Board has consistently asked new surface water management features to buffer watershed features. The Area to the North is designated as a High -Priority Protection Area in the Lino Lakes Handbook for Conservation Design. Soils in ths area are aandy, and pervious. If an infiltration train were designed into the site plan, there appears to be enough seration between the OHW and a designed rainpond/swail area. The ram pondpond area must be in an area where the Seasonafly high water table is at least 3 feet from the bottom of the pond. Please refer to (Attachment 8). The seasonafly high ground -water level should be verified. Peak flow analysis indicates a.23 cfs increase in water volume flow in a two year event, a .32 cfs increase in water volume flow in a 10 year event, and a .36 increase in water volume flow for a 100 year event for the entire site. The basin should be designed if possible to accommodate this extra surface water volume, if not for the entire site. Additiona ponding is shown in the turf areas. No surface -water analysis inforrnation is avaUable at this time. The soil areas around proposed remaining pervious areas should be protected from compaction during construction. A buffer of native plants incorporated into edges and a surface -water -treatment -train should be planted. Ground story materials should be native in the ponding and drainage areas. A1I proposed sod areas should have at Ieast 4 inches of topsoil tilled thoroughly into the subsoil as deep as possible. Adetai\wd|ondacapep|anmhouidindiosdomnorefounda1ion plants.

Aithough there is no proposed lighting fortbe added space on the church, the possibility exists that there may be a need to light the building in the future. If this should happen, than the lighting shoud be down ward focused, no -spill type lighting. 3
