Ppmr,0SAL ON -CALL ENGINEERING SERVICES 6, '4041 RFP NO.: 17..083 City oi Santa Ana Bus Stops It Is assumed that the bus line along Mile One Street will remain active. The bicycle buffer prohibits the buses to pull into the curb closest to the sidewalk, therefore a bus platform Is necessary adjacent to the outside (fans #3) travel lane, Mark Thomas will provide a few proven designs for bus stop design along corridors with Class IV bike lanes for consideration and will provide a recommendation on a case -by -ease scenario, Storm Drain Upgrades Storm drain Improvements within this portion of Mile One Street will be per the CIVs Master Drainage Plan. Mark Thomas will conduct a hydrology analysis to verify the location and sizes of the proposed Inlets and hydraulic analysis and modeling to confirm the Master Plan's recommendations for main line Improvemerits4 Water Quality Management Mark Thomas will prepare a Water Quality Management Plan (WQMP) with specific BMPS to satisfy the EIR ranuirements and the Cihi's I — Im of D-1 �t F. .,,&,,a requirements. Similar to those Installed at other parkway locations for similar projects, a low maintenance and easily implemented bloretention system, such as Fliterra, could be Installed. The unit cost of these systems Includes the requirements desired by the City of BMPs. Utilities Coordination Mark Thomas'approach to the utility coordination task Will Include the typical "ABC" process from Caltrans, where major and minor risk Items are identified. We will take a second step which Is to be located those conflicting utilities to a satisfactory level of confidence using a combination of FllterraO Bioretention System pothollng and other locating strategies that may be more cost efficient. This additional effort will reduce risks during construction and provide both the City and Mark Thomas the Information necessary to make informed decision during the design phase. 25E-629
