Requests for Proposals & Requests for Bids

Request for proposals are prepared when requesting professional services such as engineering, surveying, and plan checking. Requests for bids are prepared when contract construction projects are being bid out. City Council approval is not required to issue these requests. Council approval is obtained when a contract is ready to be executed. 

Capital Improvement Program (CIP)

City Capital Improvement projects are formulated based on available funding. Funding sources include City General Fund, State funds, and Federal funds. Outside funding requires a match with City funds. All CIP projects are listed in the Capital Improvement Program that is updated and approved annually by the City Council. The CIP document can be found here.

Currently the Engineering Division is working on several large CIP Projects. Information on these projects can be found here.

Great Streets

Great Streets is the successor program for street improvements following the Millennium Miles Paving Program that was conducted from 2000 to 2006. Great Streets 2008 and Beyond combines arterial and local residential street improvements into one program. The Great Streets Program is coordinated with the Pavement Management Plan maintained by the Engineering Division. 

Bridges & Bridge Inspections

Bridges are inspected biennially by Los Angeles County Department of Public Works (LACDPW). Bridges in the city are located at flood control channel crossings. The Jackson Avenue Pedestrian Overcrossing (at I-10 post mile 25.10) is jointly maintained by Caltrans and the City.

Storm Drains & Flood Control

The Public Works Department maintains over 100 catch basins in the City. In addition, the Los Angeles County Flood Control District owns and maintains over 400 catch basins in the City. The Alhambra Wash, Rubio Wash, and Eaton Wash are large flood control channels which run through and along the City limits.

To report flooding or problems with the storm drain system, contact the Public Works Department at (626) 308-2825 or by email.

Street Lighting

New street lights in the City are typically installed as a condition of approval for multi-family and commercial projects. Property owners in a residential neighborhood who wish to install street lights may elect to form an assessment district by which they will pay for the construction and operation of the lighting system. In areas with overhead power lines, the street lights are often owned and maintained by Southern California Edison, with the City paying for the electricity usage.

To report street light outages, contact the Public Works Department at (626) 308-2825 or by email.
