We will prepare a report presenting the results of field exploration, geoteohnical laboratory testing, and enginaering analyses, as well as conclusions and recommendations relative to the project Dolivsvablest Draft Pavement and Sot/ Matarle/ Repod, Most Pavement Report and Solt Matiadal.Report. Task 4: Survey. (options A and.e)... ........................ ..... ......, „ The KlmlayoHorn team will provide aerial mapping with supplemental ground surveys at a scale of 1" - 20' with 50 feet Interval cross :sections aiong,strests as wall as the project area for pump stations, This encompasses survey record collection; establishment of horizontal and vertical controls; monument and centerline Its preservation; and establishment of tampdrary benchmarks. Existing features such as utility covers, pavement limits, prlgats properly improvamania, curb ramps, driveways, curb andgutters, sidewalks, street lights and poles, and frafflc sights end striping will be surveyed where noodled for the proposed design and added to the base mep% ExtsUng rlghtrof way will be input per readily evaRable records.

Task 5, Nydraulir/MydrologyAnalysis Option B) Cur team will prepare a Drainage Report to address hydrology and hydraulics for the site perOrange County Hydrology Manual and Lounge County Local Drainage Manual requirements and:wlll provide design recommendations. Modifications are Intended to maintain existing drainage patterns and flows, Calculations will consist of comparing the pre- and post -project conditions at the site. Catch basins will be incorporated into design, where necessary, Le, to limit flooded width, and at low points. Deliverables, Draft hydrology and hydraulic analysis and drainage report, Final hydrology and hydraulic analysis and drainage report. Task G; Water Quality (Options A and B) KimleyHorn will develop a WQMP forte project In compliance with, and meeting the requirements of Order No. R8.2009•00301NPDES No. CAS618030, of the Santa.Ana Regional Water Quality Control Board. The WQMP will Incorporate low Impact development best management practices to the maximum extent practical. For example, the use of bloretention facilities within landscaped parkway areas will be In accordance with the United States Environmental Protection Agency (green Street standards. If proprietary items are needed, these will be Indicated In compliance with the City's adopted public contracting code, Deliverables: Draft WQMP, FinalWQMP, Task 7., Envfronmentat Studies (options A and B) .............. Kimiay-Horn Scope of Servtoas assumes that an Initial Study leading to a Mitigated Negative Declaration (I81 MND) is the appropriate CEQA documentation for the proposed project. The IS will provide the necessary background. Each of the topics contained in the Environmental Checklist will be evaluated to document the nature end extent of any potential environmental consequences and the need for mitigation. During the preparation of the IS should it be determined that the project could have significant impacts that cannot be fully mitigated, we will work with the City to Identify modifications to the project that could reduce anticipated impacts. Using the City's Initial Study Checklist, Klmley-Horn will respond to each checklist question, The analysis will use the following technical studies and data prepared by our team: Traffic Impact Study, Air Quality and Greenhouse Gas Study, Noise Study, Utilities/ Infrastructure, Gootechnical Study, Drainage, Concept WQMP, and a Phase I Environmental $ita Assessment. All other environmental topics would be studied qualitatively. Defivorablesr Initial Study leading to a Mitigated Negative Declaration (IS/MND). Kimley*Horn 1e M0077026.171 any of &ants Ana 25E-31
