• The developer has submitted a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP must be approved and implemented prior to the commencement of a grading permit. A number of modifications to the SWPPP have been identified and will need to be incorporated into the final plan as identified in the attached SWPPP memo. Site Vegetation Almost the entire site is classified as medium tall grass non - native dominated grassland. The Eastern -most edge falls into a Native dominated temporarily flooded shrubland. Trees: There are no trees within the proposed construction area.. Rare and Unique Feature Search Developer should check with the Minnesota DNR on how to develop with National Heritage concerns in the area. There is an indication from the Lino Lakes Blandings Turtle Model that we have activity and breeding on this site. Given that there is a potential for breeding and activity on this site, the site should be designed to enable Blanding's Turtle • activity. Low - profile, surmountable curbing to allow turtles to cross roads should be used. Signs similar to the signs placed in Marshan Meadows indicating a potential nesting area should be placed on along the same contour as Marshan meadows. A wetland delineation report submitted is shown on Attachment 6. Wetlands are confined to the eastern edge of the site. The wetland area is a shrub swamp type of wetland. Rice Creek Watershed District has declared the delineation as incomplete due to seasonal constraints related to vegetation and frozen soils. The report is considered incomplete until the vegetation is analyzed. Because of the rare features concerns and the shoreland overlay district, a conservation easement should be drafted that is contiguous with that of Marshan Meadows. Literature should be given to new residents notifying them of the easement and the reasons for it. Conservation easement signs should be placed along the easement line with at least one sign per frontage of easement. The sign should state that "no cutting, planting, filling or excavating should occur within the easement." Soils Soils on the proposed development site are for the most part fine sand, and Lake Beach along the lake shore. No soils should be imported or exported with out City approval. Soils must be protected from compaction and restored if
