PROPOSAL STANDARD AVENUE PROTECTED BIKE LANES 3RD TO WARNER City of Santa Ana We will prepare the traffic signal sheets for locations 1-5 using the topographic survey files, civil improvement files (where applicable), and the as-built plans. Bicycle signal heads and separate phasing are anticipated, in accordance with FHWA Interim Approval 16 (IA-16). Pedestrian improvements will include adjusted push button locations (where needed) based on new curb bulbouts. The traffic signal modification design will include existing equipment to remain, existing equipment to be removed, new equipment to be installed, and the associated notes, details and schedules. The traffic signal modification plans will be prepared in AutoCAD at 1”=20’ scale and will be designed in conformance with CAMUTCD and City requirements. This scope assumes one sheet will be prepared perunidentified intersection. The construction cost estimate will be developed based on recent bid information (if available) for similar projects. We will coordinate with Southern California Edison (SCE) to establish new service for the new signal at Bishop Street and the PHB (location to be determined). Existing service is anticipated to be utilized at locations that are modified only. Traffic signal and lighting plans will be prepared and submitted to the City with civil design plans at the typical milestones (30%, 60%, 90% and 100%). Task 5.4.1. Landscape Plans We feel the landscape design and water treatment plans are highly dependent upon each other to manage water runoff and address aesthetics along the corridor. Therefore, we will prepare a landscape construction documents with specifications for City review. All work will be coordinated with the design team and prepared using AutoCAD. The documents included are: • Irrigation Plan, Legend and Details • Planting Plan, Legend and Details • Special Provision Specifications • Planting and Irrigation Cost Estimates Irrigation Plans, Legend and Details This plan will diagrammatically lay out landscape irrigation piping, valves, control equipment, sprinkler heads and related irrigation equipment for the irrigation of planting areas, at 1”=20’ scale, specifically calling out all pipe and equipment sizing and types; and will include legend and details required to install the irrigation system. A Water Efficient Landscape Worksheet shall be provided inclusive of the Hydrozone information table and Water budget calculations (MAWA, ETWU) as required by City. Planting Plans, Legend and Details This plan will graphically locate and identify planting materials at 1”=20’ scale, including specific quantities, sizes and varieties, and will include details and a planting legend to install the plant materials. The palette will include California native or adaptive, drought tolerant plant materials. Task 5.5. Special Provisions Mark Thomas will develop the project technical special provisions using City of Santa Ana and Caltrans Standard Specifications. The special provisions will be prepared using Microsoft Word. Special provisions will be submitted at the 90% and final submittals. The City’s Front-End boilerplate contract language will be incorporated into the specifications at the 100% submittal. Task 5.6. Engineer’s Estimate Mark Thomas will develop quantities and prepare construction cost estimates using the project geometrics and surfaces developed from survey information. Cost estimates will be calculated at the 60%, 90%, and final 100% submittals.
