What is the Street-Lighting the Master Plan?
A comprehensive review and analysis of the City’s roadway street lighting system to develop strategic short-term and long-term plans for upgrading and improving the system over time What are the Goals of the Master Plan?
To ensure that all roadway lighting meets current standards while also enhancing the overall aesthetics and safety of the City's lighting infrastructure.
What is the Master Plan?
Create a lighting inventory and management software to track and maintain these assets.
Create a digital map within the software to locate these assets.
Conduct detailed inventory of all the street lighting along city streets and alleys Create a database of lighting infrastructure by identifying and mapping assets in the field and recording their condition Perform engineering analysis of existing conditions against established City standards and identify areas that do not meet them.
How was the Plan completed?
Determine the infrastructure or fixture upgrades necessary to bring the non-conforming areas or sections up to City standards.
Prepare a cost estimate associated with these upgrades and seek SCE input.
Prepare a list of short-term (approximately within one year) and long-term (within approximately five years) improvements and an associated budget.
Prepare final report with recommendations on future of lighting.
Plan completion (continued)
The City has a total of 77.7 miles of centerline roadway and a total of 3,094 street lights 2,407 lights owned by SCE (78%), 549 owned by the City, and138 by adjoining agencies A mix of various types of poles (e.g. wood, concrete, steel, etc.) and lighting technology (e.g. LED, high pressure sodium vapor, etc.) Adjoining agencies – Caltrans, LA County, Cities of Montebello, Bell, and Bell Gardens What is there in the City?

How was the database built?
Phone app developed to collect, collate, sort, and store street-light data from the field Data like pole height, type, fixture type, mast arm length, Lat./Long. etc. collected in the field The data was made available in a web-browser-based application The app provided editable information in both spreadsheet/list and map-based format The data is stored in an AWS Cloud Server
City personnel will have different access levels

How was the analysis done?
Photometric analysis was conducted using a method patterned after IES RP8-22* Illuminance method used to for intersections (amount of light falling on the surface) Luminance method used to for street sections (reflected light from street) Software used to model light patterns of existing inventory and review deficits (existing condition) Based on deficiencies, lights/poles were added and new analysis done (recommended condition) *IES – Illuminating Engineering Society
The analysis (Continued)
SAMPLE EXISTING CONDITION ILLUMINANCE ANALYSIS AT INTERSECTION
To keep costs reasonable, improvements were mostly recommended for SCE existing light/poles instead of adding many City poles/lights Recommendations were for short term (within 1 year) and long term (within 5 years) Short term recommendations included:
Fixture replacements
New mast arm/fixture on existing poles
Long term recommendations included:
New poles, conduits and power source
What are the recommendations?
742 locations total were identified for improvements
60 locations City owned and 682 are SCE
Included a number of alleyways currently unlit
Short term Improvement Estimate : $660K
City: $244K and SCE $398K
Long term Improvement Estimate : $3.32 mill
City: $991K and SCE $2.33 mill
Total Estimate: $3.98 mill (based on 2025 costs)
What are the recommendations (continued - 1)?
Maintain, monitor and update the City’s street lighting database via the Street Light Manager Implement annual software maintenance contract with app developers (LenioLabs) Use City’s current lighting standards for all future upgrades Review City lighting and fixture standards periodically as technology improves What are the recommendations (continued - 2)?
