• 2. Erosion control and tree protection measures must be installed before grading begins on the project. The City has begun strict enforcement of these requirement. 3. Individual custom grading of each will be examined to minimize impacts to the existing topography and minimize other impacts to the environment. Plans must clarify where mass grading is proposed, if any, and where custom grading is proposed. 4. The construction of rainwater gardens in individual lots may be possible, increasing infiltration of stormwater runoff. 5. A delineated preservation area on the north side of the island will be clearly marked during clearing and construction on the site. Care will be exercised to not damage valuable trees or disturb designated buffer zones. This area will remain in a natural state. Covenants will be used so property owners cannot remove vegetation in this area. Monuments will be posted delineating this area. Drainage from the rear of the homes will travel through this area allowing infiltration and reducing runoff The project approval can include a mechanism to protect this area such as covenants or a conservation easement. 6. Using roof leaders to direct runoff away from impervious surfaces will reduce the volume of runoff from the site. 7. Covenants can be included in homeowners' association by laws to prohibit the use of • phosphorous on the lawns. 8. The posting of signs and other aspects of a protection plan, as recommended by MN DNR, will be required to help protect Blanding's Turtles . 9. A flat bridge design will minimize the visual impacts compared to a truss bridge. The clearance under the bridge will be approximately 12 feet above ordinary high water level, and approximately six feet during 100 -year flood conditions, which allows for canoe access. 10. Any fill activity in the lake (below the ordinary high water level) or dewatering must conform to DNR standards. 11. If any wetland fill does become necessary, the developer must obtain necessary approvals from the Rice Creek Watershed District. 12. The City will require utility and roadway specifications that demonstrate compliance with current City standards. These will be of greater detail than have been submitted to date. 13. The City will require a pre - construction survey and monitoring program for noise and vibration (as noted above). 14. Damage to existing streets should be considered in the establishment of financial securities for a development agreement for the project. DRAFT, July 1, 2004 Pheasant Hills Preserve 12th Addn.
