Kimley»)Horn <br />Warner Avenue Street Improvements <br />1/10/2018 <br />Preparation of traffic control plans; hot -mix asphalt patching and Full -Depth Reclamation <br />Recommendations are excluded for this task. <br />Deliverables: Draft Pavement and Soil Material Report, Final Pavement Report and Soil Material <br />Report, <br />Task 4: Hydraulic/Hydrology Analysis <br />Our team will prepare a Drainage Report to address hydrology and hydraulics for the site per <br />Orange County Hydrology Manual and Orange County Local Drainage Manual requirements <br />and will provide design recommendations. Modification of existing catch basins and connections <br />to the storm drain main line are anticipated as part of the project. Modifications are intended to <br />maintain existing drainage patterns and flows. Calculations will consist of comparing the pre - <br />and post -project conditions at the site. Evaluation and recommendations are limited to the <br />impacted portion of the storm drain within the project site. Catch basins will be incorporated into <br />design, where necessary, i.e. to limit flooded width, and at low points. Evaluation of the <br />downstream or upstream existing storm drain system is not anticipated for this task. We will <br />address one round of consolidated City comments before preparing the final deliverable. <br />Deliverables: Draft hydrology and hydraulic analysis and drainage report, final hydrology and <br />hydraulic analysis and drainage report. <br />Task 6: Water Quality <br />Kimley-Horn will develop a Water Quality Management Plan (WQMP) for the project in <br />compliance with, and meeting the requirements of Order No. R8-2009-0030/NPDES No. <br />CAS618030, of the Santa Ana Regional Water Quality Control Board (RWQCB). The WQMP <br />will incorporate Low Impact Development (LID) Best Management Practices (BMP) to the <br />Maximum Extent Practical (MEP). For example, the use of bioretention facilities within <br />landscaped parkway areas will be in accordance with the United States Environmental <br />Protection Agency (USEPA) Green Street standards. If traditional LID BMPs cannot be <br />incorporated, appropriate proprietary BMPs will be selected to improve water quality. If <br />proprietary items are needed, these will be indicated in compliance with the City's adopted <br />public contracting code. We will address one round of consolidated City comments before <br />preparing the final deliverable. <br />Deliverables: Draft WQMP, final WQMP. <br />Task 6: Precise Alignment and Geometry Design <br />The project team will refine the preferred alignment provided by the City part of the RFP. We will <br />identify geometry constraints for roadway widening, turn pockets, bike lanes, sidewalks, and <br />other street features, to confirm their compatibility with the existing conditions and proposed <br />widening. <br />Establishing geometry design for the mid -street and bike lane median will also be part of this <br />work. We will incorporate traffic lanes configuration at intersections and changes of street cross <br />sections throughout the corridor considering new alignment. One review session with the City <br />staff of precise alignment will be part of this task. Design revisions will be reflected in 30% <br />plans. The goal of this task is to minimize changes through plan production phase by getting <br />stakeholders concurrence on proposed improvements. We will use the City's provided field <br />surveys for base mapping. Precise Alignment plans will be prepared at a scale of 1" = 40' <br />horizontal. <br />3 1 P a g e <br />
