Request for Stormwater Storage Waiver

Requests for stormwater storage waivers are reviewed as part of case submittals for the associated project. This form should be included in the preliminary drainage report with the applicant’s portion completed. The preliminary drainage report shall include supporting documentation and analysis as needed to support the requested wavier.

A project must meet at least one of three criteria listed below for the city to consider waiving some or all required stormwater storage. However, regardless of the criteria, a waiver will only be granted if the applicant can demonstrate that the effect of a waiver will not increase the potential for flooding on any property. Check the applicable box and provide a signed and sealed engineering report and supporting engineering analysis that demonstrate the project meets the criteria and that the effect of a waiver will not increase the potential for flooding on any property. If the runoff for the project has been included in a storage facility at another location, the applicant must demonstrate that the stormwater storage facility was specifically designed to accommodate runoff from the subject property and that the runoff will be conveyed to this location through an adequately designed conveyance facility. It should be noted that reductions in stormwater storage relating to

For a full storage waiver, a conflict with ESLO is limited to: • Property located in the hillside landform as defined in the city Zoning Ordinance • Property in the upper desert landform that has a land slope steeper than 5% as defined in the city Zoning Ordinance • Property within the ESL zoning overlay district where the only viable location for a stormwater storage basin requires blasting This full waiver only applies to those portions of property meeting one of these three requirements. 100-year/2-hour storage is allowed, but not required for redevelopment projects and development within the ESL zoning overlay. Rather, these projects must store enough stormwater to attenuate post-development flows to predevelopment levels, considering the 10- and 100-year storm events (S.R.C. Sections 37-50 and 37-51). By signing below, I certify that the stated project meets the waiver criteria selected above as demonstrated by the attached documentation.
