CITY OF ENO LAS 10/24/94 Standards for Facility Design g Design Elements In order to provide consistency throughout the City when building storm water facilities, a set of Design Standards were developed. These standards implement the Policies. They are to be used as a guide when designing any storm water facility variance from these Standards requires p within l the om e City. Flow Rate Criteria Peak storm water discharge rates and storage volumes from any watershed, subwatershed, detention basin, wetland or conveyor shall be consistent with the values shown in the plan. A summary of these rates is included under the Water Resources Inventory section of the Users Manual. Variances will be allowed if computations can be provided that demonstrate that no adverse downstream effects will result from the proposed system. Direct discharge into Rondeau, Peltier, George Watch, Marshan, Centerville, Reshanau and Rice Lake require no flow rate criteria. However, �water quality improvement structures are required prior discharging into these and other waterbodies. If the methodology is inconsistent with the City standards, and the results are significantly different from the City's, then the City results shall control. Inter- Community Flow Rates Where a variance would involve inter - community issues or significant water bodies, the watershed district shall have a review role. Any variances shall be reflected in subsequent local plan amendments thereby requiring watershed district approval. Rice Creek Watershed District has established rate control policies for various watersheds in the District. The control is to protect the drainage system from flooding problems. All discharge rates leaving the City shall be consistent with the RCWD policy of preventing downstream flooding. Local Water Management Plan Users Manual SEH NO: LINOL9402.00 Page 12
