Street Lighting ReviewStreet Lighting ReviewEvaluate Current procedures
Evaluate Costs
Interview other Cities
Interview the stakeholders, City, DVP, Mfrs, Installing Contractors
Consider alternate methods and costs1. City Owned and Maintained2. City Owned, Contract Maintenance
A. Existing StreetsB. New Construction
Measured and Analyzed City Pilot Projects
Researched the Market … Technology, Efficacy, Pricing
Determine …What can be done to reduce costs ?

Princess Anne Road Street LightingCompare - As Designed vs. Alternative
1. Higher Efficiency Lighting Fixtures exist … than DVP’sThat efficiency is not reflected in DVP rates
2. City ownership of NEW PROJECT Street lighting
Can save money
3. City takeover of existing fixtures is complex and costly
4. Tracking and Reporting of DVP System is Vague
5. Fragmented understanding of the procurement system
6. Dark Sky compliance is desirable among stakeholders
7. Color temperature 4000 - 4500 K is desirable among stakeholders
