Background 2017 Strategic Plan Initiative 2016 Community Survey

ComEd Pole Most HPS luminaire; some mercury vapor. Rate 23 – includes equipment rental and dusk to dawn flat rate. Rate 25 – includes dusk to dawn flat rate (unmetered VOMP-owned lights).

Village standard pole

Drop lens vs. flat lens. Most ComEd luminaires are HP; some mercury vapor. ComEd plans to replalces HPS and MV luminaires with LED lamps starting in 2018. Reduced wattage of equipment should reduce dusk to dawn flat rate costs. Vomp has variety of luminaires. Almost all existing luminaires are energy inefficient.

Most luminaire types are energy inefficient.

Current streetlight policy New subdivisions and/or developments are required to satisfy street lighting requirements in Village Code. Residents/businesses can request streetlight addition. PW will survey adjacent property owners for input. PW will install new Village-owned light or ComEd leased light. Few requests; low volume of new installations New streetlight construction stopped due to budget constraints in 2009

Lighting standards Village Code Illuminating Engineering Society International Dark Skies Association

Village Code Intersections End of cul-de-sacs Curves Mid – block at spacing not exceeding 300’ 87% of intersections are lit Only 16% of mid-blocks greater than 300’ long are lit To satisfy Code, both intersection and mid block metrics should equal 100%. These existing non-conformities are likely a consequence of the fact that most subdivisions were created and constructed prior to adoption of the current streetlight regulations within the Village Code; it's common for streetlight installation to be in conjunction with other infrastructure improvements related to single-family development or road reconstruction

IES rp-8 recommended practice ANSI standard for roadway lighting based on roadway type, potential for pedestrian conflict, and targeted lighting levels. Most communities design to a lesser standard because cost of compliance is high.

Dark Sky International Dark Sky Association is an organization that works to prevent light pollution. Many precepts are already incorporated into roadway design best practices and standards. IDA precepts included in designer best practices or standards include flat screen and full cut-off luminaires.

LED LUMINAIRE LED Luminaire. Village-owned standard pole. Flat lens to limit side/upward discharge. Type III distribution. High color temperature (3,000-5,000 Kelvin). Metered or flat rate. Flat rate should recoup investment due to reduced wattage (consumption). Smart Technology. Dim lights based on time of day or roadway use. Report outages.

Standard pole (aluminum).

Decorative pole.

Unit costs Activity Cost Retrofit luminaire $550 Install new Village-owned Standard Pole $8,000 Install new Village-owned Decorative Pole $9,200 Install new ComEd Wood Pole $3,600 Remove ComEd Wood Pole $1,200

Life cycle ownership costs Feature Cost/Year Village-owned Standard Pole $288 Village-owned Decorative Pole $312 ComEd Wood Pole (leased) $244 Replace ComEd Wood Pole with Village-owned Standard Pole

Retrofits Retrofit existing HID lamps with energy-efficient LED luminaires. Reduce energy usage 35%-60%. Upgrade existing intersections to LED = $48,400 Upgrade existing mid-blocks to LED = $165,000 LED lamp costs approximately $550/unit including parts and labor. Annual maintenance cost for HPS: $100 annual maintenance, $42 annual electricity, $142 net budget impact per year. Annual maintenance cost for LED: $550 upfront / $82 annual maintenance, $28 annual electricity, $32 savings over HPS per year.

Fill in unlit intersections Standard Village-owned poles. Additional energy and maintenance cost is $13,185/year.

Fill in unlit mid-blocks Standard Village-owned poles. Additional energy and maintenance cost is $226,944.

Estimated Total costs Scenario Cost Upgrade to Village Code (Standard Poles) $15 million Upgrade to Village Code (Decorative Poles) $17.3 million Upgrade to IES RP-8 Standard $20-44 million Corridor lighting program identifies addition $15 million. Decorative poles are 15% higher. Poles tend to be shorter requiring more.

Potential funding Public Sector Energy Efficiency Program Illinois Clean Energy Community Foundation Federal and State of Illinois Transportation Grants Private Sector Financing Mount Prospect Community Investment Program (CIP) Motor Fuel Tax Fund Streetlight Enterprise Fund Public Sector Energy Efficiency Program. Formerly DCEO now taken over by ComEd. Program to begin in 2018. Rebate public sector agency for energy efficiency improvements. Retrofitting of existing streetlights is eligible. Approximate rate is $1.46 per watt saved. 35%-60% reduction in wattage typical between HPS and LED. Generally a savings of between $30 to $175 per luminaire. Illinois Clean Energy Community Foundation. No streetlight grants presently offered. But have offered within last 18 months. Recent VOMP Illinois Clean Energy Grants: KBC Streetlight Conversion. KBC Bike Path Streetlight Installation. Prospect Avenue Streetlight LED conversion. Police/Fire HQ Building HVAC Replacement. Police/Fire HQ Building Fluorescent Light Relamping. Streetlight Enterprise Fund. Create enterprise fund where fees are paid by property owners > generally based on property size, frontage, or equivalent residential units.

Robert Frost School Long blocks off of Kensington. Areas recommended by Police Department to improve safety. Areas coincide with areas depicting lowest levels of satisfaction with existing streetlighting in 2016 Community Survey. Light unlit residential intersections. Also an estimated $15 million to fill in gaps in corridor lighting system. $15 million for corridor lighting and $15 million for upgrade residential lighting system to Village Code creates a need for over $30 million for street light improvements.
