Huitt-Zollars will survey visible utility features within the proposed area of improvements and identify critical utility <br />crossings that should be potholed to confirm the location so as to avoid conflicts during construction. The Huitt- <br />Zollars Team will pothole up to 5 high risk utilities in conformance with Caltrans Policy on High and Low Risk <br />Underground Facilities Within Highway Right-of-Way. The as-built plans, utility survey and pothole information <br />will be used to create athree-dimensional CADD model of all known underground utilities. <br />Task 7.1.15 Stage ConstructionlTraffic Handling Sheets <br />Huitt-Zollars will prepare traffic handling plans, which show long-term closure of lanes, detours and number of <br />available lanes. Included in these plans are signing, striping, and modifications and temporary traffic signals. If <br />necessary, Huitt-Zollars will continually evaluate and update the traffic handling plans during the design process. <br />Task 7.1.16 Construction Area Sign Sheets <br />Huitt-Zollars will prepare construction area sign sheets. <br />Task 7.1.17 Pavement Delineation Sheets <br />Huitt-Zollars will prepare pavement delineation plans and pavement delineation quantity sheets. <br />Task 7.1.18 Sign Sheets <br />Huitt-Zollars will prepare signing plans including layouts showing the locations of roadside and overhead signs <br />and details, special sign details, lighting, overhead sign and sign quantities. <br />Task 7.1.19 Electrical Sheets <br />Known utility relocation requirements will be sent to the utility company to assist the utility company in preparing <br />final power line construction documents. The City will be sent a copy of all information sent to the utility <br />companies. Huitt-Zollars will also prepare any required Utility Relocation Agreements andlor Joint Use <br />Agreements. <br />Huitt-Zollars will prepare electrical plan sheets as described below: <br />• Huitt-Zollars will coordinate with electrical utility agency (SCEISanta Ana) to verify the existing service <br />location and to coordinate new service locations. <br />• Huitt-Zollars will prepare technical specifications and special provisions for the proposed electrical work and <br />the estimate of probable construction costs. <br />Task 7.1.19(a) Traffic Signal Design <br />Huitt-Zollars will prepare plans to upgrade intersection controls, including new traffic signals. These locations <br />will include: <br />• Halladay Street North (new signal). <br />• Red Hill Avenue at Alton Parkway (modify existing signal). <br />Huitt-Zollars will prepare traffic signal design plans for the ultimate improvements. Currently, it is assumed <br />that the stage construction plans would not require any temporary signal design plans. The plans will include <br />work necessary to install the traffic signals and will conform to the requirements of the City. Sheets will be <br />prepared for each signal location showing the complete signal design. <br />Task 7.1.19(b) Ramp Meter Design <br />Huitt-Zollars will prepare new ramp metering at the following location: <br />• MacArthur Boulevard Southbound Off-Ramp. <br />• Dyer Road Southbound On-Ramp. <br />The sheets will include work necessary to install the ramp meters and will conform to Caltrans requirements. <br />One sheet will be prepared for each ramp meter location showing the complete design. <br />Task 7.1.19(c) Lighting Plans <br />Huitt-Zollars will prepare street, freeway and soffit lighting as required. The sheets will include work necessary <br />to install street and freeway lighting circuits and service connections to support a lighting system for the new <br />25D-59 <br />
