5. The presence of a high groundwater table an wetlands on and adjacent to this site. indicate that the soils and site conditions are probably not suitable for an infiltration basin. In an infiltration basin is no feasible, a wetpond will be required. 6. In general, no stormwater facilities, with the exception of necessary discharge systems, may be located inside wetland or stream buffer areas. 7. On -site detention of stormwater runoff is required per city standards. B. Treatment of stormwater runoff from paved areas must occur, per city standards, prior to discharge of the stormwater from the site or to a stream or wetland. 9. Landscaping will be required for surface ponds and basins to provide screening and an aesthetically pleasing appearance. A landscape plan must be submitted and approved during plan review. Landscaping shall be provided outside of the high water mark and may be required to be included in a separate tract under common ownership. Installation of the landscaping per the approved plan is required before final approval. The city may require formation of a Homeowner's Association to maintain all landscape areas. 10. Discharge of water to wetlands should mimic natural discharges as much as is feasible. Point source discharges should not be created where they do not naturally occur. Techniques that result in dispersed discharge, such as dispersion trenches or buried perforated pipe located at wetland buffer edges, can be used to mimic naturally occurring sheet flow into wetlands. 11. Natural wetlands may not be used to meet detention requirements for stormwater. In addition, stormwater detention is generally not allowed in wetlands created for mitigation. However, with certain types of mitigation wetlands, a restricted outlet and fluctuating water table is desired and designed feature of the wetland. Detention of clean or treated stormwater runoff may be permissible under these circumstances. Treatment of stormwater runoff is not allowed in either natural or created wetlands. 12, Approximately 3,500 GPM of water flow is available at this site at 20 psi residual pressure. 13. Any broken or damaged sidewalks shall be replaced pr the City Public Works Inspector. 14. City streets are to be kept clear of dirt and debris at all times during the construction. Dust suppression and street cleaning must occur as directed by the Public Works Inspector. 15. Permits must be obtained for all fill removed from the site and placed within the City Limits. 16. A pedestrian circulation system for the site must be approved by the Planning Director and Traffic Engineer prior to the issuance of any building permits. Walkways must allow pedestrians and wheelchairs to gain easy access from sidewalks and bus stops to building entrances through the use of paths which are physically separated from vehicle traffic and maneuvering areas. (See the city's Design and Construction Standards and Specifications Manual and Section 39.165 of the Zoning Code.) Note: modifications will need to be made to the parking lot layout in order to accomodate this requirement.
