• • should include maintenance of Silt fences when silt fences are 1/3 full. In addition, a clean -out area for cement trucks should be shown on the plan. Permanent erosion control should include the City native seed mix in buffer, pond and areas outside the retaining wall. Grading All grading in pond and buffer areas should be done with low impact track -type equipment and fenced off after initial grading to prevent further compaction. All soils on sodded green areas should be roto - tilled as deeply as possible. All top soils should be toughly incorporated into subsoil to prevent interface issue. Landscape Plan Sodded areas are indicated by the shaded areas on the Landscape Plan (Attachment 8). All sodded areas must be irrigated and shown on the plan as such. All seeded areas with sod -seed must also be shown as irrigated. All areas on the east side in the buffer areas and pond areas should use the City Native seed mix specifications. All sodded and seeded turf areas should be thoroughly tilled to loosen compacted soils, and top soils incorporated into the subsoil so that soil - interphase is not present. This language needs to be incorporated into the Notes and written into the contract specifications. The plan calls for an Interesting selection of plants. I would suggest substitutions for Greenspire Linden and White Fringetree. Greenspire lindens are a little leaf linden and marginally hardy. White Fringetree is not zoned for Minnesota. Tree Protection A tree preservation plan is not presented as it should be in the submittal. The application package should show all significant trees, the significant tree diameters, and species. This information should be placed on the grading plan. Significant trees within 25 feet of the property line, bordering the regional park should be located. The root zone areas of these trees come on to the development property. The plan should show all tree protection measures to be taken such as fence locations for protecting remaining trees, and procedures to avoid oak wilt and construction damage to remaining trees and adjacent property trees. Land cover The Lino Lakes MLCCS shows a transition of vegetation from Oak forest on the South to Tamarack Swamp (off the Site) to the East. The Tamarack swamp was degraded in the 1960's when the highway came through. This Tamarack area has a high potential for restoration in the future. The development appears to have no impediments to this restoration idea. The oak woodlands for the most part start in the project area on the South and go into the Regional Park. Efforts to maintain integrity to this woodland in the Regional Park must be made.
