B. Complete a record search with the City and utility companies.

C. Show all existing wet and dry utilities on traffic signal design plans.

D. Retain a professional survey team to perform horizontal and vertical site survey topography including intersection features and striping, drainage facilities needing replacement; and to locate the public right of way for the intersections, identify existing overhead wires that may be in conflict with traffic signal/luminaire poles and mast arms, and any vegetation or large trees that may be in conflict with proposed infrastructure.

E. Provide a conceptual, schematic 8.5” X 11” exhibit showing proposed signal phasing and signal indication layout. The intersections of N. Santa Fe Avenue & Angeles Vista Drive and S. Santa Fe Avenue & Santa Anita Drive are both three-way intersections.

F. Prepare 60%, 90% and Final Plans, Specifications and Estimates for construction of both traffic signals connecting to existing fiber optic interconnect, ADA curb ramps including any utility relocations required or relocation/removal of obstructions, pedestrian facility improvements, signing & striping and temporary erosion control.

Traffic Signals shall be designed in conformance with Attachment A, Guidelines for Traffic signal Design Plans. Each traffic signal will have its own design, specifications and construction cost estimate; and will have its own DWG number assigned by the City. Each design plan set will include:

i. Traffic Signal and Signing & Striping Sheets: The City will provide AutoCAD templates for traffic signal design and signing & striping sheets, which include border & title, and traffic signal and signing & striping design and notes.

ii. Traffic Signal Design Sheets: The traffic signal design will show all pertinent aspects of the signal design including existing utilities (including overhead), signal hardware, new conduits by directional boring, loop detection, phasing diagram, signal mast arm-mounted signs, streetlights as needed, tables and schedules, construction notes, etc.

The base map showing existing improvements (curb & gutter, sidewalk, curb ramps, striping, signing, etc.) will be obtained from the survey in Task D above.

The signal pole foundation and base plates are to be shown to scale in the exact location where they are to be built to ensure that they meet Caltrans standards and are within public right of way and not in conflict with existing utilities, curb ramps and other physical constraints.

The signal plan is to be drawn at 20 scale.

iii. Fiber-Optic Interconnect Design Sheet: This sheet will show fiber-optic interconnect equipment, design and construction notes to connect to the new traffic signal into the existing fiber-optic network. The City has the as-built drawings needed to complete this task.

iv. CCTV: Include one CCTV camera at each location and designating the specific corner where the camera will be installed for optimum visibility.

v. ADA Curb Ramps: New ADA compliant curb ramps, existing curb ramps in need of upgrade to current ADA standards, existing driveways and street entrances in need of upgrade to current ADA standards, must be schematically shown and called out on the signal design sheet.

vi. Signing & Striping: A signing and striping design sheet at 20 scale.

vii. Erosion Control Sheets: Erosion control sheets using City AutoCAD templates.

• Construction and post construction BMPs and erosion control design. Sample BMP details and notes are available for review and electronic dissemination by the City

2. The above design sheets can be rearranged to reduce the total number of sheets as space allows. For example, the Traffic Signal Notes may be placed on the standard improvement plan title sheet and the applicable Construction Notes may appear on the traffic signal design sheet itself. Another example is to combine the Traffic Signal Notes and the signage and striping notes and details into one sheet.

3. A traffic signal design plan shall use NEMA phasing conforming to the California Manual on Uniform Traffic Control Devices (CA MUCTD), Part 4, Highway Traffic Signals.

4. The traffic movements on the major roadway shall be designated phases 2 and 6.

Phase 2 is to be used to designate either the northbound or eastbound movement. If the two intersecting streets are apparently of equal importance, the City's Engineering Department shall designate which of the two is the major roadway.

5. North shall always be oriented up or to the right on all design plan sheets. The major roadway shall always be horizontal on the plan.

6. Signal design plans shall be drawn at a 1" = 20' scale.

7. Pole identification numbering (or lettering) shall always increase clockwise around the intersection with the lowest numbered pole being always on the corner where the controller cabinet exists or is to be located.

8. Conduit run identification numbering shall start at the farthest conduit crossover from the controller cabinet corner and always increase in clockwise direction toward the home run pull box on the controller cabinet corner. The final home run conduits shall have the highest identification numbers.
