4 . Water quality enhancement of stormwater runoff from the <br /> paved areas must occur, per city standards, prior to <br /> discharge of the stormwater from the site or to a stream or <br /> wetland. <br /> 5. Stormwater detention/retention, quality protection, and <br /> enhancement requirements for this project shall be those <br /> requirements in effect at the time of application for Public <br /> Works permits. Currently, stormwater quality enhancement is <br /> required when 10,000 square feet of pavement that will be <br /> exposed to stornwater and vehicles is created by an <br /> apartment project. Three options for stormwater quality <br /> enhancement are presented in the current city standards. <br /> The least preferred option is allowed only if the first two <br /> options are infeasible in the opinion of the Public Works <br /> Department. The options for stormwater quality enhancement <br /> are, in order of preference: <br /> 1) An infiltration basin designed and constructed <br /> accordinq to city standards. <br /> 2) A wetpond designed and constructed to city standards. <br /> 3) A baifle-type oil/water separator followed by a <br /> vegetated swale, both designed and constructed <br /> accordinq to city standards. <br /> 6. Covered parkinq area is not counted towards the 30,000 <br /> square feet of pavement as lonq as these areas drain instead <br /> to the sanitary sewer. <br /> 7. Landscaping w!11 be required for surface ponds and basins to <br /> provide screening and an aesthetically pleasing appearance. <br /> A landscape plan must be eubmitted and approved during plan <br /> raview. Landscaping shall be provided outeide of the high <br /> water merk and may be required to be included in a separate <br /> tract under common ownership. installation of the <br /> lendscaping per the approved plan is required before final <br /> approval. <br /> 8. all water quality enhancing facilities must be designed in <br /> accordance with city etandards, and should be sized to meet <br /> the requirements of all future expansion on the site. <br /> 9. All collected surface water exiting the subject property <br /> muet be conveyed to the nearest established, stable drainage <br /> course, within the naturally occurrinq drainage basin, by <br /> pipe or by an approved swale in a manner that will not <br /> result in erosion or flooding. Sufficient downstream <br /> information and analysis must be provided to enable the City <br /> to determine that this requirement is being met. <br /> Appropriate easements will be required if conveyance must <br /> occur across private property. <br /> 4 <br />
