The following additional erosion controls shall be implemented on the site: a. All proposed slopes 3 feet horizontal to 1 foot vertical (3H:1 V) should be covered with erosion- control blanket. b. Silt fence should follow existing contours as closely as feasible to limit the potential for gully erosion along the edges. c. Any sediment that collects in storm sewers, ponds, or other water-management features shall be removed. d. Street sweeping shall be performed if sediment collects on streets. e. If erosion occurs at the outlets of the storm sewer pipes, the applicant will be responsible for correcting the problem to the satisfaction of the VBWD. 9. To prevent soil compaction,the proposed infiltration area shall be staked off and marked during construction to prevent heavy equipment and traffic from traveling over it. If the infiltration facility is in place during construction activities, sediment and runoff shall be kept away from the facility, using practices such as diversion berms and vegetation around the facility's perimeter. The infiltration facility shall not be excavated to final grade until the contributing drainage area has been constructed and fully stabilized. The final phase of excavation shall remove all accumulated sediment and be done by light,tracked equipment to avoid compaction of the basin floor. To provide a well-aerated,highly porous surface,the soils of the basin floor shall be loosened to a depth of at least 24 inches to a maximum compaction of 85% standard proctor density prior to planting. 10. All disturbed areas shall be vegetated within 14 days of final grading. 11. The applicant is responsible for removal of all temporary erosion-control measures, including silt fence,upon establishment of permanent vegetation at the project site as determined by the VBWD Engineer and/or Inspector. 12. Valley Branch Watershed District shall be granted drainage easements which cover(a)land adjacent to stonnwater management facilities(including permeable pavement areas)and lowlands up to their 100-year flood elevations and (b) all ditches, storm sewers, and maintenance accesses to the stormwater management facilities. 13. The required drainage easement shall be recorded with the Washington County Recorder's Office. 14. Return or allowed expiration of any remaining surety and permit closeout is dependent on the permit holder providing proof that all required documents have been recorded (including but not limited to easements)and providing as-built drawings that show that the project was constructed as approved by the Managers and in conformance with the VBWD rules and regulations Tony Willger,SAHS VBWD Permit#2015-25:Stillwater High School and Pony Activity Center,Oak Park Heights February 24,2016 Page 3 Thank you for your cooperation with the District's permit program.
