Consulting Services Agreement between City of San Leandro and Last revised June, 2025 NCE for Lewelling Blvd. Class IV Bike Ways Project Exhibit A – Page 5 of 8 During design development, we will discuss and confirm pavement treatment alternatives, curb replacement, noncompliant curb ramps, drainage issues, and a summary of utility location data (Optional Task 8) and possible utility conflicts/concerns. With the 30% plans Green Infrastructure will start to be considered, and carried forward in the project. The Consultant will identify and incorporate stormwater features such as rain gardens in accordance with Alameda County’s C.3 requirements. NCE’s traffic engineering subconsultant, Fehr & Peers, will assist with the design of traffic signal equipment designs and provide peer review of the bike facility and striping design. We will also submit an engineer’s cost estimate in MS Excel format. It is assumed that the City will require a 2-week review/comment period once the preliminary P&E package is submitted. Task 3C Deliverables: One reproducible copy of 30% plans, engineer’s estimate, and summary of agreed-upon design criteria and decisions Task 4 – Pavement Design 4A Pavement Condition Survey NCE will perform a visual pavement condition survey based on distresses. The surveys will generally cover the travel lanes and shoulders and serve as the primary source to determine the appropriate pavement treatment for Lewelling Boulevard. The survey will note the presence of load-related and environmental distresses as they pertain to developing appropriate pavement treatment options. Potential base repairs will be identified, marked with white paint, and recorded using GPS based software. Our scope of work and condition surveys do not address issues including but not limited to traffic, safety and road hazards, geometric issues, or short-term maintenance that should be performed (i.e., potholes that should be repaired). Task 4A Deliverables: Summary of localized pavement repair locations. 4B Limited Pavement Coring NCE will collect limited pavement section core samples (4” – 8” diameter cores) on Lewelling Boulevard at locations determined by NCE. The pavement coring information will help inform the construction design to anticipate pavement section thicknesses, particularly for potential deep pavement repairs, shallow inlays, concrete median construction, and plantings. Our current fee estimate assumes up to 12 to 16 core locations that can be accommodated in one day of coring. For each core sample, NCE will measure and record the thickness of asphalt and concrete encountered in the pavement structural section, including the presence of any pavement reinforcing fabric. The AB thickness will be measured/estimated at up to two locations and presence will be noted at the remaining locations. No bulk samples of subgrade will be obtained for laboratory testing. NCE will arrange for traffic control services during pavement coring, which will conform to the latest standards contained within the California Manual on Uniform Traffic Control Devices (CA MUTCD) Part VI and the Caltrans Traffic Manual Chapter 5 “Traffic Control for Construction and Maintenance Work Zones,” as well as any local requirements that exist. We will also obtain an encroachment permit for pavement coring, if required. NCE will also develop a map showing proposed coring locations for the City to review and to facilitate the encroachment permit if required. Task 4B Deliverables: Encroachment permit application.
