guidelines and in Microstation V8i Computer Aided design and Drafting (CADD) format. <br />The horizontal datum shall be NAD 83 and the vertical datum shall be NAVD 88. <br />D. WATER QUALITY. The Consultant shall coordinate with the City for the Low Impact <br />Development (LID) requirements on the project and to prepare a Water Quality Management <br />Plan (WQMP) for the project. Consultant shall provide BMPs with appropriate size based on <br />treatment and peak flow rates, freight to job site and one year of maintenance to include units <br />and cost in the engineer's cost estimate. <br />The selection of Best Management Practices (BMPs) will always be subject to site specific <br />conditions and the Consultant will be required to perform the research into the site specific <br />conditions (e.g. prior contamination, depth to groundwater, soil conditions, interfering <br />utilities, etc.) that could preclude infiltration. The Consultant shall also perform the required <br />soils and/or infiltration testing per the Technical Guidance Documents, as necessary to <br />design the infiltration system assuming it is the selected LID approach. <br />Please find information and links to relevant documents and regulations at the following site: <br />http://ocwatersheds.com/documents/wgmp. <br />E.

Development of Plans, Specifications and Estimate (PS&E): <br />a) All reports, plans, specifications and quantity calculations shall conform to criteria, <br />policies, procedures and standards of the City. The Consultant shall use the <br />boilerplate for cut sheets, specifications and estimates provided by the City. <br />b) The plan development shall include four (4) milestone deliverables -30%, 60%, <br />95% (pre -final) and 100% (final). All plan sheets shall be prepared at 20 scale <br />unless noted otherwise. The necessary plans for each PS&E package shall include, <br />but not be limited to: <br />1.

Landscape & Irrigation Plan <br />c) All calculations for the design and quantities shall be submitted as part of the PS&E <br />submittal requirements. Quantities for all contract pay items shall be substantiated <br />by calculations. Quantity calculations shall be neat and orderly and shall show all <br />sketches, diagrams, and dimensions necessary to allow them to be independently <br />used by field inspectors during construction. All quantity calculations shall be <br />independently checked and substantiated with independent calculations. <br />d) Electronic files for all CADD (in Microstation V8i), reports, and calculations shall <br />be submitted at the end of the contract or when requested by the City. <br />City of Santa Ana RFP 18-072 <br />
