• • • A conservation or drainage easement should be described for all surface -water treatment areas as well as from the shoreland Impact Zone to Marshan Lake. City control over all surface -water treatment features should be maintained. Signage should be placed at the boundaries where the easement areas are described. A Conservation Easement should be described for these areas. Site Vegetation The proposed site includes medium -tall grass non - native dominated grass land, short grasses on upland soil, Saturated non - native dominated graminoid vegetation, Native dominated temporarily flooded shrub land (See attachment 3). The required tree inventory is included as Attachment 4. The inventory lists 80 significant trees, 44 significant trees saved, 428 total trees on the site, and 313 total trees saved on the site. Most of the deciduous trees are Boxelder and Cottonwood. Evergreens are mostly Red Pine. Rare and Unique Feature Search Section 17 has a rare feature listed in the Minnesota DNR National Heritage Database. It must be the responsibility of the developer to check with the Minnesota Department of Natural Resources concerning any possible impacts to this rare feature, and report back to the City on any findings. There is an indication from the Lino Lakes Blandings Turtle Model that we have activity and breeding on this site (See attachment 9). The absence or presence of Blandings Turtle consideration should be verified with the Minnesota DNR. This concern is independent of the identified rare feature in Section 17 by the Minnesota Department of Natural Resources. Given that there is a potential for breeding and activity on this site, the site should be designed to enable the Blanding's Turtle activity and breeding on the site, or access to remaining habitat immediately off the site. Low profile, surmountable curbing to allow turtles to cross roads should be used. Open space in a buffered area of sand (Ponding areas ?) would help to maintain a breeding site for this turtle. The ponding areas should be planted with the City native seed mix with no incorporation of topsoil in order to supply nesting habitat for turtles. A wetland delineation report submitted is shown on Attachment 6. Wetlands are confined to the bank area of Marshan Lake. Env. Bd. Mtg. 1/26/05 Page 3 Item 5B
