If amending onsite topsoil, documentation must be supplied to the City certifying that the amended material meets this specification prior to installation. • Planting details /specifications must be included on the landscape plan and shall address among other things o Planting depth (1s set of primary roots shall be at finished grade) o Only prune out dead/broken /deformed branches at time of installation o Removal of upper portion of wire basket and burlap after being placed in planting hole • At the time of installation, all shrubs must be at least twenty -four (24) inches in size (either height or width, whichever is applicable per species). • The landscape plan identifies areas to be covered with turf. Please note that sod is required for turf establishment. Any alternative to the sod requirement requires City Council approval. • Should City Council approve the use of seed rather than sod, details will be required outlining application rate(s) and installation method. • Upon acceptance of landscaping by City, a two (2) year maintenance guarantee is required to ensure survival of plantings. Please submit a revised landscaping plan that addresses these matters. Tree Preservation: This site is devoid of any significant tree cover and therefore, no tree preservation plan is necessary. Engineering Review Reviewer: Tim Himmer, City Engineer thimmei a ci.ramsev.mn.us 763 -433 -9893 The following comments are offered regarding the October 5, 2010 plans by Landform Engineering Company: Grading and Drainage: The building floor elevation should be set to be above the adjacent grade of the public streets while meeting ADA accessibility guidelines. The grade from the building to the property lines and extending to the limits of the shared accesses must be set to match the plans for the future buildings and parking. The COR Development utilizes regional stonnwater ponds for rate control and water quality treatment. Each individual site needs to provide additional water quality treatment through the use of rain gardens, water quality treatment structures, or other BMP's. The plan is proposing to install a conventional storm sewer system (inlet structures and pipes) with the east half of the site discharging to a proposed design on the adjacent Residence at the COR property and ultimately to the public system, and the west half directed into the public system in Sunwood Drive. Drainage calculations were received but additional information is required for the appropriate sizing of the proposed Aqua -swirl structures. The AS -3 and
