Task 7: Wafer Quality Proposal for Santa Ana Main Street Corridor Improvements Kimley-Horn will develop a Water Quality Management Plan (WQMP) for the project in compliance with, and meeting the requirements of Order No. R8-2009-0030/NPDES No. CAS618030, of the Santa Ana Regional Water Quality Control Board. The WQMP will incorporate Low Impact Development (LID) Best Management Practices (BMP) to the Maximum Extent Practical (MEP). For example, the use of bioretention facilities within landscaped parkway areas will be in accordance with the USEPA Green Street standards. If traditional LID BMPs cannot be incorporated, appropriate proprietary BMPs will be selected to improve water quality. If proprietary items are needed, these will be indicated in compliance with the City's adopted public contracting code. Deliverables: Draft Water Quality Management Plan, Final Water Quality Management Plan Task 8: Design Development Plans The project team will refine the fixed elements of the approved Vision Plan and develop a more detailed approach to the street closures, crosswalks, sidewalks, street furnishings, bulb -outs, parklets and lighting to check their compatibility with the existing conditions and technical analysis of previous tasks. The first phase of the cultural trail, establishing a visual language for the entire trail, will also be part of this work. The development of the plazas/parklets at the proposed vacated streets will be vetted during this phase to ensure their compliance with traffic, fire access, and neighborhood agreement. Two review sessions with the City staff of the design development package will be included in this task. Design revisions will be limited to two rounds. The goal of this task is to maintain the Vision while revising elements as required in this more detailed phase of work. A cost estimate will be undertaken at the conclusion of this phase to ascertain the final elements to be developed during the next phases of work. Deliverables: Design Development Plans Cask 9: Kimley-Horn will develop a street improvement plan for the construction of new bulb -outs, ADA improvements, and roadway pavement improvements for the implementation of these a; features as shown in the RFP Exhibits. The plans will show horizontal and vertical design information. j Roadway plans will be prepared at a scale of 1" _ 20' horizontal and V = 2' vertical for profiles. We j will use the field surveys obtained in Task 2 for base .�,� „ mapping. Vertical design information for construction of new bulb -outs, and non-standard curb ramps will be indicated on the plans with elevation callouts. Curb and flow line profiles will be shown if determined reasonably necessary. Details and typical sections will be added as indicated in the drawing list provided with our fee. Necessary adjustments to surface utility features will be identified and addressed with call outs and construction notes. We will prepare details for items that deviate from published standards. Plan preparation will be coordinated with the City, and other agencies such as Orange County Fire Authority, Community Development Agency, OCTA, and utility companies. We assumed design for bulb -outs will be Kimsey )))Horn 14 TRRD77004.17 I City of Santa Ana
