PARKS AND RECREATION ADVISORY BOARD AGENDA ITEM MEETING DATE: May 19, 2003 (Agenda Item Prepazahon Date. May 6, 2003) ~ AGENDA TITLE Proposed City of Boulder Lighnng Ordmance REQUESTING DEPARTMENT Jan Geden, CPRP, Director of Pazks and Recreat~on Jeff Lakey, Supenntendent of Pazks and RecreaUOn Planmng and Development Kate Bernhardt, Associate Pazks Planner FISCAL IMPACT DepencLng on the outcome of the ordinance, approximately $500,000 to $1,500,000 over a mmimum of 8 or a maximum of 15 yeazs PURPOSE Tlus is an mforma6on item for the Boazd. The staff is prepued to help Facihtate the transmittal of PRAB comments to the Planmng Boazd and/ City Council. The Plamm~g Board and City Council are reviewmg a proposed lightmg ordinance. The Plamm~g Boazd will have considered on May 15, 2003 the lighting ordinance by the trme of the May 19, 2003 PRAB meetrng. City Council will, on June 3, 2003, then heaz a first readtng on the ordinance and a second reading tn early July. P&R staff will orally update the PRAB about the outcome of the Plamm~g Boazd meeang. BACKGROUND Tlus hghtmg ordinance is designed to reduce the amount of energy requued to sustain lighdng systems, to improve safery associated with lighdng in specific use azeas, and to reduce light pollutaon (hght spillover or glaze beyond the use azea for which the lighting is mtended). In addiaon to new construcuon, the ordmance is designed to address exisdng development If passed, all elements of existuig light~ng systems will need to be replaced that do not meet the standazds of the new ordmance. The draft ordinance proposes a 15-year compliance penod +'"' however the Planning Board has asked stafF to review an 8-yeaz compliance period. '~-.. AGENDA ITEM # VII - A ; PAGE 1 Pazks and Recreauon staff has completed a cursory mventory of pazk and recreahon facility ~ outdoor hghdng along with a preliminary approximat~on of the cost to upgrade our existing lighnng systems to meet the currendy proposed ordmance standazds. The miual nummal cost estimate is roughly $500,000 to $1,500,000 in 2002 dollazs, nohng that Stazio Phase 1 and 2 would meet the ordmance standazds without replacements. A more comprehensrve evaluauon would require assistance of a hghting engmeer, budget for those fees, and addiaonal time. Our cost approximation dces not mclude costs to upgrade to hghhng attached to recreation buildmgs. Tlus cost would be managed by Facihry Assets Management (FAM). No fundmg has been idenufied m the current CIP to address tlus potential expenduure A Planning Departmen[ statement about the ordmance status is included m Appendix A. ANALYSIS Our current mventory of Pazks and Recreauon outdoor hghting mcludes 36 sites with: • 84 pazking lot lights • 130 walkway and security hghts (some mven[oried m FAM study) • 11 hghted ballfields • 10 hghted teiuus courts • 1 hghted golf dnvmg range ^~~w Because FAM has prepared an inventory of its facihues mcludmg those below, the Pazks and Recreadon inventory does not include • The Boulder Mall • 13th Street, • Cen[ral Park, or • Civic Center Complex The costs to implement the orcLnance aze based on a quick staff mventory of light poles and recreation light~ng systems and a rough estrmate of replacement costs if most of the lights, with the exceptron of 7 ballfields at Sta2io, required ad~ustment or replacement. The Pazks and Recreation hghpng mventory was compared with the FAM inventory to avert any potenaal double counung of light~ng elements. A technical analysis of the system, addressing all of the components of the hghting ordmance (light levels, pole heights, cut off features, white hght source bulbs only, no fixtures near trees m pazking lots, umformity rauo, etc.) would require professional assistance and its more speciahzed analyses. Our cursory and conservative appmaumanon of cost impacts (2002 dollazs only) to bnng the Pazks and Recreahon outdoor hghUng mto comphance with the proposed ordmance is $500,000 to $1,500,000. The tugher end esamate is predicated on the "worst case" for the Department where there would be significant re-arrangement of parkmg lot and walkway hghting poles, ~^~, foohngs, and winng/conduit, mcludmg pavement, ungation, and landscape repair, and lunng AGENDA ITEM # VII - A ; PAGE 2 i engineers qualified to design and prepaze construction drawings for these pubhc improvements ~.,.. The lower end eshmate mcludes replacement of the Mapleton Ballfield hghts and less sigmficant upgrades of fixtures and "bulbs" ~hght sources) mostly on exishng poles and mvolvmg httle site work. The Parks and Recreadon Department staff will be connnumg a dialog with the Plannmg Department on these issues and further studying and detaihng the overall impact to department srtes and budgets and will wnhnue to mform the Pazks and Recreation Advisory Boazd of new developments and impacts to our facihties. PUBLIC COMNIENT AND PROCESS Ttus item is bemg heard at this pubhc meet~ng, as advertised m the Dazly Camera STAFF RECOMNIENDATIONS Staff supports the goals of the hghtmg ordmance but has concems about the detuls of its implementarion and funding schedule. 1 Staff would prefer a 15 yeaz compliance period over an 8 yeaz compliance penod to reduce the annual costs. 2. Staff would hke to ask the Council to consider amehoraung the orduiance requirements on a site-by-site basis after a careful review of the current performance and planned life- ,w. cycle replacement schedule for existmg, funcuonmg hghtrng systems. It would help the ~ department if a compliance schedule could be developed that matches the life-cycle and renovation schedule for existing systems. The use of existing facilities for theu full Lfe cycle may be more econocmcally and environmentally sustaznable than replacmg and discazding them eazly. If the final ordmance overlooks these issues, then the wst to bring the Department's facilihes mto compliance wfll stuft other funding prionhes and potenaally delay other projects for a longer penod of ume. 3. Staff is also concemed about the issue of code comphance with other plamm~g standards if implemennng the lighhng ordmance affects the chazacter and quahty of the physical environment that is regulated by those codes Questions for PRAB members: 1. Do you agree with the staff recommendat~ons~ 2. Do you have any additronal comments regarding the hghhng ordmance wluch you would hke the Planmng Board or Council to consider as they review it?

The city council also finds that the value of other fixtures required to be replaced by tkus ordmance aze muumal, and that on balance, the burden placed on ihe property owner is mimmal, given the value of such fixtures agau~st the benefits gained by such replacement, wkuch is a substantial .-~+ decrease of unnecessary hght polluhon. o..- AGENDA ITEM # V~, PAGE,~,Z Sechon 4.
