Depending on the specific project location some drainage improvements may be required, which would r*` C TAIT & Associates, Inc. on -Call Engineering Services with the preparation of special construction details. The preparation of a detailed drainage hydrology g Hfl � The City of Santa Ana is seeking a civil engineering firm to provide design engineering for approximately e 1000 feet of street improvements. The street improvements include Implementation of the city's a, "Complete Street" program that has already been Implemented at the existing street Intersections, a ! widening on one side and pavement rehabilitation. The existing roadway median was improved to it t ultimate condition on a previous project, but this assumption will be verified as part of the project's i preliminary design and reconfirmed at the 65% design phase. Since the Project's right of way has already Rf been acquired based on the City's "Complete Street "program; the environmental assumption for this project assumes that the preparation of supporting documents for a Negative Declaration will be required. TAIT will prepare a preliminary striping plan and typical street section to obtain the preliminary approvals and identify potential Impacts to the adjacent private properties. 'V' Depending on the specific project location some drainage improvements may be required, which would r*` C typically indude the extension of existing street storm drain laterals and new street catch basins and local depressions. The construction requirements for these improvements can typically be addressed with the preparation of special construction details. The preparation of a detailed drainage hydrology and hydraulic study Is not warranted or proposed for this project, Also, since the proposed I Improvements will cover less than one acre the preparation of a Storm Water pollutant Prevention Plan (SWPPP) and a Water Quality Management Plan (WQMP) will not be required. TAIT will incorporate any a water quality provisions of the city's Complete Street program that may apply for this street segment t and preparo specification to address construction storm water runoff. Rf Utility notices will be distributed and record data will be Incorporated into the project's Base Map. Utility impacts will include coordination with SCE for relocation of street lights on the side of the street being widened; however based on the city s RFP Scope of Work Description no other utility relocations 'V' are anticipated. This assumption will be confirmed prior to the City Kick off Meeting. For the street repaving typically utility adjustments for sewer and storm drain manholes, water and gas valves, and other utility appurtenances are anticipated and will be Identified on the plans. The scope of work required on this contract includes monthly Project Team Meetings, Design Review n & Meetings (after the City competes their reviews), two design field walks (one for base map preparation and a second priorto 96% PS&E QC review), implementation of the City's Complete Street program, q geotechnical investigations, PS&E preparation and construction engineering support services. In addition u If necessary the TAIT team can prepare Traffic Control Plans and provide federal funding assistance during design and construction as optional services. Agency coordination or processing of another agency encroachment permits Is not anticipated as part of this project; however, this assumption will be 6 confirmed prior to conductingthe project's Kick off Meeting. Roadway Signing & Striping plans will also he prepared far the street segment incorporating bike lanes ..r „ based on the following street typical section for the. existing 120 -foot right of way width. • Two 10 -foot wide parkways with a six foot sidewalk and 4 -foot of landscaped parkway • Two 4 -foot wide curb adjacent bike lanes with a 4 -foot buffer separation. • 36 -foot wide pavement area for three traffic lanes In both sides of the existing median r • The remaining 12 feet of the total 120 -foot ROW is assumed to Include the existing sheet median. It is TAIT's understanding that the roadway signing will be replaced in kind and any existing damaged roadway signs will be noted for removal and replacement based on City directions. New signing will �t Include bike lane signing and "NO PARKING" signs. �n TAiT„ n Page i 7 rs 25E-566
