Streets and Sidewalks

Sidewalk and Curb Installation:
Requirements governing streets and sidewalks can be found in the City Code Section 12, and in DPW-published "Specifications for Highways Covering Residential and Industrial Developments.

Street Lighting:
In the fall of 2016, the City has started a project to convert all its streetlights to LED technology. The project is scheduled to be completed in the spring of 2017 with the conversion of approximately 9,700 lights. For a list of frequently asked questions for the conversion work, please see below.

For maintenance issues with the streetlights, repair service can be requested by calling the Public Works office at 780-3175. Please be advised that very limited repairs will be performed on existing streetlights until after the completion of the LED conversion project.

City of Cranston Streetlight Conversion Project
Frequently Asked Questions

1. What kind of streetlights does the City of Cranston currently have?

The City currently uses High Pressure Sodium (HPS) streetlights. While the most common streetlight technology in most cities across the country, HPS streetlights are not very energy efficient, cast a yellow/orange light which it is difficult to see color, and tend to produce light that is not of optimal quality.

2. What are LED streetlights?

LEDs (light emitting diode) is a technology that has been used in solid state lighting for decades. More recently, LED technology has advanced to streetlight applications. LED streetlights are extremely energy efficient, have long lifespans, and produce better color and light quality than typical HPS streetlights.

3. What color of light are LED streetlight fixtures?

Contrary to the yellow/orange light that HPS fixtures produce, LED streetlight fixtures are a cooler, white light under which it is easier to see true colors. The City chose a 3,000 Kelvin color fixture, which is a warmer color than the 4,000 Kelvin colors that many cities are currently using.

4. Why do the new LED fixtures appear to be dimmer?

Although the new LED fixtures may appear to be dimmer, they are actually not dimmer than the fixtures they replace. Whereas the HPS fixtures would typically pool the light underneath the fixture, the new LED fixtures are more efficient at delivery and produce an even disbursement of light.

5. Why is the City of Cranston doing an LED streetlight conversion project?

The City is interested in reducing its energy consumption and maintenance costs associated with streetlighting. Installing LED streetlight fixtures will save energy, require less maintenance, and will provide citizens with better light quality on streets and roadways.

6. How many streetlights is the City of Cranston replacing with the streetlight conversion project?

The project will replace approximately 9,700 streetlights throughout the City of Cranston.

7. How much will the City of Cranston likely save when it upgrades to LED streetlight fixtures?

The project is expected to save approximately $500,000 per year in costs, through a combination of lower maintenance and energy consumption costs.

8. How long will the project last?

The project began in the summer of 2016 with an audit that provided precise locations and characteristics of existing streetlights. The project is now commencing the installation phase, and is scheduled to be completed in the spring of 2017.

9. What are the benefits of the LED streetlight fixture project?

The benefits of this project to the City of Cranston include:
? Reduced energy consumption resulting in energy savings and Greenhouse Gas emissions.
? Reduced maintenance costs.
? Better visible light for Cranston citizens.
? Standardized LED fixtures throughout the city.

10. What is the City doing with all of the streetlights it is removing?

The existing High Pressure Sodium lights will be removed and recycled.

11. The new LED is too bright. Can the LEDs be adjusted?

Please note the new LED streetlight fixtures function differently than the previous HPS fixtures, in that they provide a whiter, more efficient light. As such, they can initially appear brighter than the previous HPS fixtures because the whiter light allows the human eye to see more, yet they actually use far less energy than the HPS fixtures. Historically, individuals who initially view LEDs as too bright, eventually adjust to the more natural light within 90 days. The City requests that residents who view LEDs as too bright to wait 90 days in order to adjust to the light.

12. My house is too dark at night now. Can the LEDs be adjusted?

LEDs are more focused than HPS lights, which mean that more light is focused on the sidewalks and road. HPS lighting was more spread out in all directions. The main objective of streetlights is to illuminate streets and sidewalks to provide a safe environment at night for motorists, bicyclists, and pedestrians to share the road. The new LED fixtures cannot be further adjusted.

13. What City department is the contact group for further questions and to report outages of streetlights?

The Department of Public Works can be contacted at 780-3175 to answer any further questions or to report a streetlight outage. If possible when reporting an outage, please provide us with the pole number of the streetlight of concern. The number is a tag installed by National Grid and is located at about eye level on the pole. This will assist the City in assigning work to repair crews.

Street Paving and Repairing:
Historically, the city has spent close to $500,000.00 per year paving and repairing city streets. The Department of Public Works welcomes resident input regarding conditions of roads and need for repairs. All requests are given proper attention and consideration when the yearly work list is being compiled.
