These requirements are found in Chapter 4-2 of the City's Stormwater Management Manual. 11. If the future use of the site will result in the potendal for accidental spills of chemicals, includiug oils or fixls, to ffie City's sanitary sewer, and Accidentat Spill Prevention Plan will need to be prepaz•ed per the direction of the Industrial Pretreatment Program. 12. All ct emicals or products of a hazardous or toxic nawre that may be used or stored on the site must be stored under cover and isolated from the storm drainage system. 13. City Streets are to be kept clear of dirt and debris at all times during the constcucdon. Dust suppression and street cleaning must occur as direcuxl by the Public Works Inspector. I 14. A one-yeac warranty is required on the public improvements for an amount not less than 10% of the wst of construction and shall run for one year from the date of issuance of the first Occupancy Permit for the project. 15. On-site watermain will be staked within an easement to the City. The easement must be submitted to the City prior to the issuance of permits. 16. As-builts of storm sewer, sanitary sewer, and water systems must be submitted per City Design an� Construction Standards and Specifications for Development. 17. An on-site and downstream drainage analysis wili be required in order to d�fine the site's existing drains:ge patterns and potential effects of the development on downsueazn drainage systems. All collected surface water exidng the subject properry must be conveyed to the nearest established, stable drainage course, within the naturally occurring drainage basin, . by pipe or by an approved swale in a manner that will not result in erosion or flooding. If the site contains portions of more than one sub-drainage basin, the amount of arca in each subbasin after development should not be greater than the area in each subbasin before development. I8.

Treatment of stormwater runoff from paved areas must occur, per City standards, prior to dischazge of the stormwater from the site or to a stream or wefland.

The preferred options for stormwater treatment are: 1) An infiltration basin, if suitable soils exist on the site 2) A wetpond 3) A constructed weHand. 20. All stormwater facilities must be designed in accordance with City standards. If none of the above stormwater treatrnent options aze feasible in the opinion of the City's Public Works Department, a biofiltration swale (designed and constructed in accordance with Ciry Standards) will be required to trc:at stormwater runoff. 21. Where soil charactcristics aze suitable az►d other site conditions do not preclude their use, roof runoff systems designed and constructed in accordance with City standards should be used to infiltrate roof top runoff to the maximum exten[ feasible.
