LED Streetlight Replacement Project

Transcription

1 City Council Workshop Agenda Item #3 May 8, 2018 LED Streetlight Replacement Project For several years, the City of South Portland along with a consortium of other communities have been working to allow municipalities to purchase and operate the streetlights within their communities from Central Maine Power (CMP). Now that these efforts are complete, the City is in the process of converting approx. 1,900 streetlights to LED fixtures. At a recent meeting, Council approved the planned purchase of these streetlights from CMP. Now we are faced with the question of: what do we replace the existing lights with? The City has been evaluating the possible streetlight fixtures and lighting options and conducted a pilot project at five sites in South Portland. The City received feedback on color temperatures and the different fixtures. The various sites were: Testing different color temperatures: Site 1: Broadway from Ocean to Cottage Site 2: E St Site 3: Broadway & Westbrook St Site 4: Pine St & Chase St Testing different fixtures: Site 5: Wermuth Rd in Redbank Village In addition to an online public survey, the City requested feedback from the Police, Fire, Public Works, and Bus departments. As noted in the attached memo from Sustainability Director Julie Rosenbach, the departmental overall preference differed slightly from the public feedback, but was also varied depending on the department. Public Works was mostly concerned with the glare (wanting the mid-color temperature) while the Police response preferred the higher-color temperature (whiter). Based on this feedback, staff is recommending the Cree fixtures as a 3,000 Kelvin temperature. We will explore these results with you in greater detail at the meeting, with the intent of obtaining Council feedback as to which manufacturer and color temperatures the City should select for the new LED streetlights. This input will inform future design and costing recommendations to be completed by RealTerm, the consultant with which the City is working to complete an investment grade audit. The City s Planner Director (Tex Haeuser), Finance Director (Greg L Heureux), and Sustainability Director (Julie Rosenbach) will be at Tuesday s meeting to provide further information and answer questions.

ROSENBACH Sustainability Director To: Scott Morelli, City Manager; Linda Cohen, Mayor; City Council Members From: Julie Rosenbach, Sustainability Director CC: Tex Haeuser, Planning & Development Director; Greg L Heureux, Finance Director Date: May 4, 2018 Subject: LED streetlight survey results & recommendations As one of the steps in the process of converting approximately 1,900 streetlights to LED fixtures, the City conducted a pilot project to give community members the opportunity to provide feedback. Five pilot sites were set up at various locations around the city to test different variations of color temperature and fixture types on both local/residential streets and main arterials. Three color temperatures on the lower end of the Kelvin spectrum (2700K, 3000K, and 4000K) and three different fixture types (Acuity, Cree, and Eaton) were tested. Testing different color temperatures: Site 1: Broadway from Ocean to Cottage Site 2: E St Site 3: Broadway & Westbrook St Site 4: Pine St & Chase St Testing different fixtures: Site 5: Wermuth Rd in Redbank Village The pilot ran for the month of April, and a total of 27 people responded. Overall, the public preferred the 3000K color temperature lights and the Cree fixtures (see the survey results attached). City staff from the police department, fire department, bus service, and public works were also asked for their input. With a public safety perspective, they indicated a mixed preference for 3000K at two locations and 4000K at two locations. They also indicated a preference for the Acuity fixtures (see the survey results attached). Recommendations Staff recommend going with the 3000K lights for several reasons: 1) there was a clear preference for this color temperature among the public and several department reviews, 2) the American Medical Association supports the conversion of streetlights to LED technology at

ROSENBACH Sustainability Director lower Kelvin levels, specifically 3000K over 4000K, which is in line with this feedback, 3) the 2700K lights are new and therefore not widely in production so their availability is limited, and 4) the difference between 2700K and 3000K is minimal and often not able to be determined. Staff recommend going with the Cree fixtures. The public clearly favored the Cree fixtures while departmental input favored Acuity. In looking at what other communities have chosen, both Portland and Scarborough selected Cree fixtures and Falmouth is likely to select the Acuity fixtures. Both the Acuity and the Cree fixtures have benefits, and staff weighed them equally, but ultimately decided to recommend the Cree because the Cree fixtures were designed to have less glare, a key complaint of LED streetlights and staff chose to go with the fixture most recommended by the public.

Whit light is better than yellower color.

10 Q6 Comments: Answered: 18 Skipped: 9 # RESPONSES DATE 1 did not get out to Redbank or Westbrook and Broadway 5/1/2018 8:04 AM 2 Yes My Mother Lives on Bayview Ave. And The Street is Very Dark.. The Light Between 33 And 55 Bayview Was Removed a Few Years Back. The Neighbors Have Complained How Dark And Unsafe It Is.. I Hope That Would Be Considered For Replacement... Thank you Very Much 3 I feel like you're asking me to choose between variants of "too white." These are all noticably whiter than the current street lights. Feels more like security than ambiance. If I had one outside my bedroom window, I would prefer something with more yellow tones. 4 For site 2 on E Street, I thought the A choice was better (for the environment it was located at), but that might not be best for more of a residential area 4/30/2018 5:43 PM 4/30/ :23 PM 4/30/ :13 AM 5 Thank you for the opportunity to comment on these lights. 4/29/2018 8:49 PM 6 this is stupid survey without any clear way to respond. 4/27/2018 7:33 PM 7 A seem to be brighter and I can see better 4/27/ :39 AM 8 The map for e street extremely confusing, can not tell landmarks on street. I am judging by the sign on the pole, not the map. 4/27/ :33 AM 9 How in the whole world is anyone expected to have any faint notion of a clue either these photos provided? 4/27/ :25 AM 10 I walk a friends dog on Bayview Ave every Saturday evening and this past winter has been very difficult. It is very dark and very unnerving when people approach you with their own animals and you can't even make out the persons face. Please restore the lighting in our neighborhoods and I beg you to start with Bayview Avenue. Sincerely, Sherre Maynard 11 Clearly you don't want anyone to take the survey. Expecting us to spend a night driving around to these locations, referring to the tiny pictures of the streets to figure out what A,B,C represents, taking notes... seriously. 12 Will you restore the street lights you removed several years back? Specifically, the lights on Broadway between Orlando St. and Whitehall Avenue? 13 The brighter and whiter the light, the better! The yellow bulbs,which may attract fewer bugs, are way too dim- making a drive through Redbank on garbage night into a visual obstacle course. 4/26/2018 5:36 PM 4/26/2018 2:38 PM 4/22/2018 7:14 PM 4/19/2018 2:02 PM 14 I think this light looked like the warmest glow. It is important that we don't have lights that give our community a cold, glaring look 4/19/2018 9:08 AM 15 I'm not sure what any of the questions mean in terms of color temperature and pattern since they're just images from Google maps with letters and arrows. LED street lights would be nice though, especially in the Country Gardens subdivision where I live. There are a lot of dim areas at night. 4/13/ :04 PM 6 / 7

11 16 C is less harsh; both lights on Chase and Pine shine into my home now and I have to keep curtains closed. Code in So. Portland states that lights can't invade other person's space... could the arch be changed a bit 17 You need to figure out how to direct the light down. I believe there are visors or shrouds just for that purpose. The way it is now is light pollution, or invasion. There are led lights on the Housing Authority building next to my house. We don't need night lights. We pile pillows up on our bed headboard because the lights shine in our faces. Through our blinds. I've been tempted to shoot them out with a slingshot. 4/10/2018 8:22 PM 4/6/2018 9:29 AM 18 Sure hope Elsmere is on this list. We have "0" streetlights as the only "1" we had is burned out. Very dangerous street right now. Accident looking for a place to happen. 4/5/2018 4:27 PM 7 / 7
