• <br />• <br />Pheasant Hills Preserve 12th Addn. <br />page 9 <br />5. A delineated preservation area on the north side of the island will be clearly <br />marked during clearing and construction on the site. Care will be exercised to not <br />damage valuable trees or disturb designated buffer zones. This area will remain <br />in a natural state. Covenants will be used so property owners cannot remove <br />vegetation in this area. Monuments will be posted delineating this area. Drainage <br />from the rear of the homes will travel through this area allowing infiltration and <br />reducing runoff. The project approval will include a mechanism such as <br />covenants or a conservation easement to protect this area. <br />A covenant will be required as part of the homeowner association documents as a <br />condition of approval. <br />6. Using roof leaders to direct runoff away from impervious surfaces will reduce the <br />volume of runoff from the site. <br />This will be considered with house and lot design. <br />7. Covenants will be included in homeowners' association bylaws to prohibit the use <br />of phosphorous on the lawns. <br />A covenant will be required as part of the homeowner association documents. <br />8. The posting of signs and other aspects of a protection plan, as recommended by <br />MN DNR, will be required to help protect Blanding's Turtles . <br />This is a condition of approval. <br />9. A flat bridge design will minimize the visual impacts compared to a truss bridge. <br />The clearance under the bridge will be approximately 12 feet above ordinary high <br />water level, and approximately six feet during 100 -year flood conditions, which <br />allows for canoe access. <br />The new design includes these features. <br />10. Any fill activity in the lake (below the ordinary high water level) or dewatering <br />must conform to DNR standards. <br />This will be addressed with project inspection. <br />11. If any wetland fill does become necessary due to the revised bridge design, the <br />developer must obtain necessary approvals from the Rice Creek Watershed <br />District prior to City Council approval of the preliminary plat. <br />The bridge design must be reviewed by the RCWD. <br />12. The City will require utility and roadway specifications that demonstrate <br />compliance with current City standards. These will be of greater detail than have <br />been submitted to date. <br />The City Engineer has reviewed the submittal. <br />13. The City will require a pre - construction survey and monitoring program for noise <br />and vibration (as noted above). <br />A plan has been submitted and must be executed as part of construction. <br />
