- <br />t I Storm Crain Master Plan ' <br />w Phase 2 j RFP NO, i 6-02 <br />Once the technical analysis is completed for the proposed facilities a cost benefit analysis will be <br />prepared. This will summarize capital as well as life cycle costs, storage capacity and/or runoff reduction, <br />as well as water quality, environmental benefits, and other benefits (i.e. social benefits) associated with <br />each of the alternatives. The cost benefit analysis will include a triple bottom line sustainability analysis <br />including social, economic, and environmental costs and benefits. This information will be necessary to <br />complete the applicable grant applications. Once the relevant technical information has been evaluated, <br />our team will work with the City to research, select, and complete grant applications using similar <br />strategies used in previous successful grant applications. These strategies will focus on the hazardous <br />and deficient conditions currently existing throughout the City and explain the critical nature for <br />implementing the proposed strategies. Incorporating triple bottom line benefits into the application will be <br />key to explaining the synergies the proposed LID strategies will have while providing public safety through <br />flood mitigation. Our team will also provide ongoing support to direct the City Staff on the grant application <br />processes. <br />If requested by the City, critical flooding locations may be evaluated using more advanced modeling <br />techniques, such as coupled 1- and 2-dimensional modeling, to better understand the area flooding <br />conditions, potential benefits and most feasible solution. Advanced methods can be used to evaluate <br />locations where surface flows and subsurface facility flows interact in an unsteady manner. Surcharging <br />and backwater in subsurface facilities and overland flow in topographically flat areas commonly occurs. <br />Michael Baker had great success in coupling dynamic and non -dynamic modeling for the City of <br />Redlands, City of Tustin, City of Laguna Woods, and the County of Orange. Our extensive experience in <br />advanced modeling has given us the knowledge and understanding to identify what key elements of a <br />drainage system would benefit, and would not benefit from dynamic modeling. <br />Page 18 <br />INTERNATIONAL <br />20C-22 <br />
