MCFADDEN AVENUE PROTECTED BIKE LANE AND BICYCLE BOULEVARD PROJECT CITY OF SANTA ANA 4y • A design capture volume worksheet for each drainage area. • A BMP Site Plan with impervious/pervious areas, improvements, and discharge points. • An operation and maintenance program and identification of maintenance responsibility. • Infiltration feasibility documentation with geotechnical field explorations. It is assumed that Green Street BMPs will be incorporated to the maximum extent practicable (MEP) consistent with USEPA guidance. This scope assumes that the Green Streets design approach allows the project a pathway to MS4 compliance by designing to the MEP in lieu of the sizing criteria required for other Priority Projects. Hydromodification analysis and design is not required for this project since the project will not impact the runoff rates or times of concentration. A draft WQMP will be submitted to the City of Santa Ana for review with the 60% PS&E milestone submittal. Comments will be addressed, and the final document will be submitted for approval with the 100% Final PS&E. Task 3.3 — Geotechnical Investigations (Optional Task): Dokken will work with our subconsultant NOVA to provide temporary traffic control as necessary to conduct geotechnical investigations. Borings will be explored to make recommendations on project infiltration and percolation rates. Geotechnical borings will be taken to a depth of between five and ten feet over a two-day period at approximately 5 locations where bulb -outs may be designed with a potential to treat storm water. A draft and final Geotechnical Report will be submitted and revised as needed. Task 3 Deliverables: Draft/Final Drainage Memo; Draft/Final WQMP; Draft/Final Geotech Report Task 4 — Public Outreach Task 4.1 — Public Outreach Meetings (2): Dokken will conduct community outreach by the facilitation of two (2) public outreach meetings/workshops. Outreach to the surrounding communities for the public workshops will occur with information in English and Spanish. We will create Meeting Agendas, Presentations, Renderings, Exhibits, and Comment Cards for the meeting. Workshops will be held in person or virtually depending on State and Orange County COVID guidelines. Meeting materials, in English and Spanish, will include fact sheets, maps, exhibits, and other content that can be printed, emailed, and utilized for social media and websites. We recognize the Southwest Senior Center has been utilized for previous community workshops. Task 4.2 — Draft/Final Public Outreach Summary Reports (2): Dokken will prepare Meeting Minutes to summarize the points of discussion and areas of concern highlighted at each of the public workshops. The Meeting Minutes, along with a summary of workshop materials provided and photos taken during the events will become part of the Draft and Final Public Outreach Summary Reports. Task 4 Deliverables: Facilitate Two (2) Public Outreach Meetings1workshops; Prepare/Provide Meeting Materials; Fact Sheets and Informational Handouts; Social Media/Website Contenfi Draft/Final Public Outreach Summary Reports Task 5 — Utility Coordination Task 5.1 — Utility Agency Letters 1-2-3 (A-B-C): Dokken will create a Utility Coordination Matrix to track contract information and communication with utility companies. Our proven utility coordination process matches the state and federally approved processes and involves sending out Letter No. 1's or A -Letters to request as-builts to research all existing utility infrastructure including franchise utilities. Letter No. 2's will be mailed to each utility company having facilities within the limits of project improvements that have a potential to have conflicts with the proposed work. Included in the Letter No. 2's, or B-Letters, are liability determination questions that seek to determine who has prior rights of the facility in question. Finally, we will send out Letter No. 3's, C-Letters, or Notice to Owner Letters notifying utility companies of project construction timelines to coordinate relocations or adjustments before or during construction. Task 5.2 - Utility Base Mapping and Conflict Resolution: Dokken Engineering will perform site visits as needed to confirm the utility mapping obtained against topographic features provided by the survey team. We will create a Utility Conflict Matrix to reconcile any discrepancies, identify potential D®KKCN Page 1 3 ENGINEERtNO
