Issues of Ownership
 Initial Cost
 Energy Cost
 Repair / Replacement Cost
 Staffing and Equipment
 Storage of spare poles and fixtures
 Metering Complexities
 Transfer of ownership of existing assets
 Consider “City” maintenance vs. Contractor maint

A Few Findings …
1. Higher Efficiency Lighting Fixtures exist … than DVP’s
That 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
