Establish Engineering Design Criteria. Consultant will provide preliminary engineering services to establish the design criteria for hydraulic and hydrologic design requirements prior to initiating the preliminary design process. The necessary planning criteria and standards will be established to ensure the required level of flood protection is provided to meet the various jurisdictional agency requirements, and are in conformance with City and guidelines. All elements of the Master Plan of Drainage will be prepared in accordance with the procedures established by the SBCFCD. This work item will include establishment of the following critical design features: • Hydraulic controls • Street inlet requirements • Outlet requirements • Local drainage system hydraulic modeling • Review of master plan design assumptions • Distribution of flows to the proposed storm drain and street section • Critical design water surfaces (committed elevations) • Allowable street flooding and storage • Deficiency upgrade requirements • Allowable design deviations (i.e., min. Flood protection levels) A memo summarizing the recommended design criteria and guidelines will be prepared for City review. This document will serve as an initial reference framework for future decisions as work progresses and unique opportunities are encountered.
