PARKS AND RECREATION ADVISORY BOARD AGENDA ITEM MEE1'ING DATE: Mav 20, 2002 (Agenda Item Preparation Date: May 20, 2002) AGENDA TITLE: Update On Water Conservation Efforts REQUESTING DEPARTMENT: Jan Geden, CPRP, Director, Parks and Recreation Doug Hawthorne, CPRP, Parks Superintendent Teri Olander, Acting Recreation Superintendent Kate Bernhardt, Acting Parks Planning & Construction Superintendent FISCAL IMPACT: Undetermined PURPOSE: The purpose of tkus memorandum is to provide an update to the Boazd concemmg the Department's Water Conservation proposal for 2002. The City of Boulder is expenencmg a potenhal ma~or water cnsis, not seen m almost 50 years, due to a much dner than normal wmter and spring, and a lack of snow pack m the mountams wluch feeds our reservoirs The City of Boulder is takmg a lead role m reducmg its water use for irngauon, and the Pazks and Recreauon DeparUnent was asked to develop a plan for reducmg water for ungat~on by 20% ANALYSIS: Attached is a plan that was submitted to the Duector for Pubhc Works - Uuhties, and the City Manager's Office late last week. Staff has been worlung on tlus plan and did not complete it unhl after the May PRAB packet had been sent. The Plan oudines imgarion reducrion strategies for plantmgs m new or renovated park sites. The Plan also recommends water reductions for vanous types of landscapes and facihnes, including pnmary athlenc facihties, general park azeas, and specialty sites, such as the Andrews Arboretum and Columbia Cemetery. Finally, the Plan addresses an issue regazding Scott Carpenter Pool Staff is recommendmg filhng Scott Carpenter Pool this season Public Works and the Crty Managers Office have not approved this Plan. .~- ~,..~ AGENDA ITEM # IV-A PAGE 1 PUBLIC COMNIENT AND PROCESS: Tlus item is bemg heazd at ttus pubhc meeUng, as advertised m the Da~ly Camera. STAFF RECOMMENDATION: This is an mformahon item only ATTACHMENT A. Water Conservation Program for Urban Parks, Recommended Program to Reduce Irrigation and other Outside Watering ~ ..~ AGENDA ITEM # IV-A PAGE 2 a 16, 200 ~ ,~ Water Conservation Program for Urban Parks Recommended Program to Reduce Irrigation and other Outside Watering The City of Boulder is exper~encmg a ma~or water cnsis due to a much drier than normal wmter and spnng, and a lack of snow pack m the mountams which feeds our reservoirs. The Parks and Recreation Department has been asked to take a leadmg role to conserve imgat~on water and potentially take drasuc steps to ehmmate new planhngs Over the past few days, Parks and Recreauon managers and supervisors have been meet~ng to determme a plan for reducmg water The City overall has asked all residents to wt back on all water used by 10%, which means at least a 20% decrease m water used for imgahon purposes Parks and Recreahon staff aze w~llmg to take the lead on the water reduction program, but are proposmg a balanced approach to this effort Pazks and Recreation staff momtors imgahon systems m over 75 separate sites. There ts over 12 5 million squaze feet of imgatable landscapes m the urban pazk system, which rely mostly on domestic treated water for ~mgation. The Flatirons Golf Course and Watson Pazk imgate with d~tch water, as well as portions of Foothills Commumty Pazk and Valmont Park The developed south shore of Boulder Reservoir ~s ~m~ated from Left Hand Water, which the C~ty pays to use In 2000, the Department used over 193 ~,,,,, million gallons of water to imgate parks The figures for 2001 were mcomplete, but the Department did not use al] of rts allocahon A key success of our imgaaon program is an abihty to track and momtor the use of water In the past, Publ~c Works has been responsible for manually readmg meters at the begmmng of each imgation season, once or twice dunng the summer and then at the end of the season. In the past water meter readmgs have been mconsistent, unhmely and we have often questioned some of the figures from ceRam meters Dunng the past year, Pubhc Works has completed mstallahon of new water meters that can be read from vehicles, or outside meter pits usmg handheld devices Paul Lander m Pubhc Works has purchased a few handheld devices and has expressed an mterest m traznmg our staff to use these devices this season so we can momtor water through the meters each day, if rt is needed. We aze also implementing the first phase of the Motorola Computenzed imgahon system that will also provide us with flow mformation through master valves tied m with computers. This system will not be implemented m our urban parks unt~l someume m 2003 The golf course, Pleasant V~ew, Mapleton, Staz~o I and II and Scott Carpenter ballfields will not be t~ed m to this system at this time. Until such ume as we complete th~s system and /work uut a mutual agreement to utilize our computenzed data, we will be workmg closely with Pubhc Works this summer to momtor our imgation use m a more timely and accurate manner ~".` ~ Water Conservation Proaosal The City is askmg all users to reduce overall watenng by 10% We beheve the plan that ~ the Pazks and Recreation Department is proposmg offers a balanced approach to addressmg this issue, without potent~ally sacnficmg some of urban parks landscape and turf azeas We are concerned about long-term affects to turf and aesthet~cs of our puks with a total elimmation of water m many pazks Once the drought ends, and we are able to imgate normally agam, the public may not be as forgrvmg and understandmg as to why our park and recreation fac~lit~es are less functional and/or unsightly There may also be more water or chemical treatments needed m the future to re~uvenate turf, or to establish new turf and planungs m areas of loss The followmg are spec~fic proposals for reducing water The proposals for reduct~on aze for anhcipated peak use times Weather will be a factor m reducmg the need for water even further. The Park and Recreaaon proposal m this report offers a reduced watenng time up to 60% m many cases. Pubhc Works has already rev~ewed and approved a proposal outhned m a recent e-mail to Ned Williams from Kate Bernhardt concemmg irngation and planUngs at newly developed pazks, such as Valmont and Elmer's Two-Mile Parks. This report mcorporates the previously approved strategy for the conservation of water at park construction pro~ects Staff is proposmg several over reachmg strategies that are the basis for our overall reduchon recommendahons They are ~ ~ Heavily used and programmed athletic fields need to be adequately ~mgated for safety reasons and for revenue generahng potenual to the DepartmenL Water reductions will be enacted m penpheral areas, but the playmg surfaces need adequate water so that we don't lose turf Facilities that fit this category mclude Stazio and Mapleton Ballfields, Pleasant View Fields and Scott Carpenter Ballfields 2. Adequately imgaung newly planted trees or shrubs or existing, older trees that are showmg signs of stress should be a pnonty for water use The Department has a ma~or mvestment m these lac~dscapes and needs to ensure that plant matenal is not iost due to a lack of adequate water I~iewly planted landscapes that aze imgated through dnp methods should not be cut back on water, as this is the most effecuve method to ~mgate trees and shrubs 3. Imgatmg ma~or facilities that use ditch shazes should be reviewed separately to ensure that reducmg water does not affect future allocations of d~tch shares. F7atirons Golf Course ~s imgated through semor drtch share nghts from Howard Ditch There are potential ways to reduce water usage at the golf course, but we should not ~ust pass on extra water to downstream users, if there ~s a potent~al for a challenge to our future water shares 4 The Department will manage our park landscape sues usmg all of the best available -.~t cultural practices Practices that would benefit the reduchon efforts might mclude, 2 but no[ hmited to mclude mcreased aerauon, mcreased mowmg height m general park areas and the use of mulch m shrub and unplanted flowerbeds All imgation #^ systems will be progr~unmed to run m the late evemng hours or early morning hours ~-- to maac~rruze the water efficiency and mm~mize evaporauon loss 5 It is imperative that Public Works read al] water meters at least once per month and shaze this mformaUOn with us m a umely manner Public Works now has capab~hues of new meters that can be read remotely ar~d that mformahon is crmcal to managmg our water consumption appropnately Saecific Recommendations A. PARKS CONSTRUCTION PROJECTS Valmont Citv Park: • The proposed sod mstallation for the large open mult~-use turf azea at Valmont City Pazk was canceled on May 3, 2002 • A new dnp imgation system is bemg mstalled m the proposed multi-use turf area to sustam 170 trees recenfly planted m this azea • The entire multi-use turf area will be seeded w~th annual rye and hydromulched to provide a quick erosion control cover crop and to d~splace weed growth. The newly seeded area will be watered mimmally to support the germmation of the grass stand This azea will be mowed regulazly throughout the summer to keep weeds a cmmmum f--~ height. In the fall, if the water ava~lability ~s sufficient, the weeds will be erad~cated, the srte regraded, and the turf mstalled. • Signage will be provided on the parksite to mform the pubhc about the water conservahon measures and the delay of compleuon of Phase 1 • This area of the park w~ll be mamtamed as a construcuon site and will not be opened to the pubhc for use No temporary restroom facil~ties will be provided on the pazk at th~s time The public will be able to use the walks and trails m the park • In addition to the 170 new tree plantmgs, there aze a few exisang shrub, tree, and perenmal plantmg beds at the new pazk Watenng, pnmazily dnp and some low water spray will be prov~ded to sustam the plant matenal • Ex~stmg sod at the pazk (ngh[-of-way stnps watered by Netafim /underground imgation) and a small azea at the main entry sign will be watered mmimally to complete root estabhshment and to sustam the turf, tapenng off to the same water imgation schedule determmed by the Pazks Mamtenance staff for other exisang pazks to ach~eve the City requested 10% reduction. • Annual flower planhngs have been canceled for this new park site • Imual cost estimates for the new tree dnp system, temporary grass cover, re-mobihzauon and grade preparation for a future turf mstallation, not mcluding the cost of the sod, is roughly $50,000 The contractor will hold the current umt cost for the turf if the mstallat~on proceeds m the fall. ~ ~ 3 Elmer's Two Mile Park .... • Construction of Elmer's Two-Mile Park will proceed to mclude completion of earthwork, utilities, hardscapes, tnbutary tra~l, soft surface trails, bndge, play area, ~ and imgation system The construcuon contract will not include new sod or planungs. Dry land seedmg for erosion control and wetland plantmgs (dependmg on the hydrology of the site) w~ll be mstalled. Any watenng provided to establish the erosion control dry land seedmg will be arranged wuhm the overall Parks and Recreation Department goal of a 10% reducuon m water use The construction contract will be revised to re-mobihze the contractor m the fumre to complete the park construcUOn and landscapmg when the water availabiltty s~tuation improves. • Costs for re-mobilization and add~tional work to complete the landscape will be available at a future date Footh~[Is Communitv Park: • Installauon of 50 warranty trees for th~s spnng has been canceled Warrantee tree mstailaUOn will be rescheduled m fall if the water availab~lity srtuaUOn improves • Costs for rev~sed planting schedule and remobilization is approximately ~2500 North Boulder Recreation Center: • Mature trees wh~ch were transplanted to provide space for the new bu~ldmg w~ll be hand watered once a month Landscapmg the existmg srte to repair destrucuon caused by the bulldmg pro~ect was scheduled for a fall mstallation Staff w~ll '~° evaluate how to proceed with this landscapmg m September, based on water ~"" availab~hty and water conservauon needs B.

Specialry Areas a. Flower Pro re am - The Department ordered thousands of annual flowers through Busch Greenhouses m November 2001 Busch has been growmg these flowers and we were to take dehvery on them begmnmg May 2002 Busch has been contacted about potentially el~rrunatmg most of the order. We aze attemptmg to set a meetmg with Busch dunng the week of May 13, 2002 Our reduction strategy (see below) ehmmates most annual flower plantmgs ~ b. Peazl Street Mall - no changes aze anucipated for the Pearl Street Mall area. `"""` Flowers will be planted as ordered, however, there ~s a recommendauon for eLmmahng hangmg flower baskets (see reducuon strategies below) c Columbia Cemeterv - imgaUOn system consists of manually watenng azeas with a hose Imgahon occurs only dunng the day, normally takes 5 days to water the Cemetery by manual system In 2002, over 4 null~on gallons of water was used to imgate the Cemetery. d. Andrews Arboretum - 7 imgation zones, 1-dnp zone • Dunng peak season, watenng is done 7 days/week, 30 mmutes/zone/week = 210 minutes/zone/week The zones cover both plant matenal and a limrted amount of sod, which is not on a sepazate zone • Five zones have new planungs this yeaz, and all the zones have 2-3 year old plantmg scattered throughout. • No annual flowers will be planted. All beds will be heavily mulched e. Commumtv Gazdens • Includes gardens at the Longs Gardens, Footh~lls Commumty Park and the Hickory Park s~te ""` • Each s~te has a number of hose b~bs ava~lable for gardeners to water vegetables 8 f Fisher Geramum displav at East Boulder Commumtv Park ~ "'*r' • Pots of geramums donated by Fisher Geramum Company for public display There aze 182, 18 mch pots F~sher bnngs their customers to the site to see many new vaneties of geranmms This azea is open to the general pubLc for viewmg • Imgated by a dnp imgation em~tter to each geramum pot Reduction strateEies a Flower Pro~~ r~m • Proposal is to elimmate annual flowers at all pazks except for Pearl Street Mall, flower beds at F1a[irons Golf Course azound the pro shop, flower beds outside of the Chautauqua Dmmg Hall, flower beds outs~de of both East Boulder Commumty Center (both the Recreation Center entra~ce and Semor Center), and the entrance to South Boulder Recreahon Center We would propose plantmg these few beds w~th less water mtense vanehes, and would develop one or two educaUonal xenc planhngs usmg nauve and or waterwise perenmals We would educate the ciuzens on the process, plant choice, imgahon, mulch, IPM methods etc, through signage, pamphlets, newspaper, etc We believe that there is an educational opportumty for ciuzens, as well as an econonuc ~mpact to attract customers to our revenue producmg faciliues. All other annual plant beds would be heavily mulched to prevent weeds Additionally, we would not remove tulip or other bulbs this summer from the annual .,.- beds not planted to allow for some spnng color next year b. Mall • Recommend ehmmahng hangmg flower baskets from hght poles on Pearl Street Mall These take more water to mamtam and the water dnps from the hangmg basket onto hazdscaped surfaces c Columbia Cemeterv • Proposal is to ehmmate hand-watenng turf m Cemetery, due to the mefFicient and ume-consucmng methods of providmg tlus water d Andrews Arboretum • Proposal is to water 3-4 times/week, 20 mmutes/zone = 80 riunutes/zone/week • No annual flowers will be planted All beds will be heavily mulched e. Commumtv Gazdens • Contact Growmg Gardens (who manages program) and encourage commumcahon with gazdeners to enact water savmg plans for [he gardens ~+~. 9 Develop signage about conservmg water to be placed on bulletm boazds throughout garden area ~,,,~ Check hoses and connecaons at each garden site f Fisher Geranmm D~splav • Consider keepmg display for the summer, as the geranium pots are imgated via mdrvidual dnp emitters to each geranmm pot 6. City Parks irrigated by Ditch shares • Includes Watson and portions of Footh~lls Communrty Park • Normal watenng schedule - 5 times/zone/week • Reducuon strategv mcludes ~mgaung 2-3 hmes/zone/week Th~s is dependent totally on availability of ditch water 7. Scott Carpenter Pool • 50 meter pooi, 350,000 gallons aze used to fill pool, 11,200 square foot sucface azea, 40 yeazs old that is scheduled to open for the summer on June 8, 2002. The pool uses approx. 14,Q00 gallons per day. • Pool has not been filled for the season but ~s scheduled to be fiiled dunn~the next couple of weeks. • Pool is used by thousands of annual and punch pass patrons, day care, pnvate ,.,~ schools, pnvate swim clubs and summer camp groups This ~s the only long course ,,,, pool m the area for Boulder Sw~mmmg and Mas[ers • Department averages 120 children for lessons Monday-Thursdays so total potential attendance for the four 8-week sessions could be 480 children for the summer season of lessons at Scott Carpenter In add~tion the Department offers 2 Lifeguard trammg classes scheduled at Scott Carpenter wh~ch will ~mpact 25-30 people • Due to the age of Scott Carpenter, the Department believes there is some water loss from leaks m the pool. Normal operauons would show a loss of approximately 5,000 gallons/day Th~s wouldn't mclude any loss due to dramage problems or cracks. • Spruce Pool (which was re~ovated in 2001) with a surface azea of 7,200 square foot loses approximately 2,OOOgallons/day Spruce Pool is covered with a retractable cover each mght to reduce heat and water evaporat~on loss. • Possible leakage of the Scott Carpenter pool may be due to cracks m the pool shell, mechamcal system leakage (pumps, pipmg, filters, etc ), and pool dram and equalizmg valve leakage • FAM found that approx 1,500 gallons of water per day runs mto the pump prt m the filter bu~ldmg A sump pit was mstalled two years ago to catch water from the pump house so it woulddt go mto Boulder Creek • Based on the evidence of leakage, FAM concludes that the ma~or source of leakage is from the mechamcal system pipmg or pool dram valve FAM replaces the equahzmg valves each year and assumes they aze not the problem The p~pmg and drun valve are located underground at the deep end of the pool on the west side These items ,.. would normally be replaced when the pool shell was replaced. Once agam, fuRher to testmg would be required with the pool filled and mechanical system operaaonal to determme the leak rates at these pomts !"^ • Department will mvestigate the possibihty of purchasmg a retractable pool tarp for ~-' Scott Carpenter This could be a ma~or budget expense and the Departmen[ is unsure of availability of th~s product or the length of t~me to have u on site Additional staff might be needed to open and/or close the facility to properly cover the pool Department Recommendation: Due to the cunent closure and renovat~on of NoRh Boulder Recreation Center, the Department has already shifted programs and general swim use to other mdoor and outdoor facilities. Add~tionally, both East Boulder Commumty Center and South Boulder Recreation Center pools are scheduled for annual shut down muntenance dunng the summer of 2002. The pool serves many individuals and groups m the Commumty, generates ~obs for 21 hfeguards, two assistant managers and 6 swimrrung mstructors, and produces mcome to the City. Addrtionally, Spruce Pool already has neaz capacity numbers that would be negatively affected by the mcreased usage from not opemng Scott Carpenter pool. It appears the Scott Carpenter pool uses approximately 14,000 gallons per day, and loses approximately 8,500 gallons per day due to some type of leak This represents 2% of the total water m the pool. FAM can reroute the I,500 gallons per day wa[er collected m the pump pit back to the pool rather than samtary drams. This will reduce the total water use to 12,500 gallons per day and reduce the net loss of water due to leakage to 7,000 gallons .... per day. Further teshng should be conducted by FAM to deternune the source of leakage ,„,,,, as best we can Teshng would be done before the pool opens and repeated when the pool is closed and before it is dramed. FAM beheves that attemptmg to repur cracks m the pool could actually make the s~tuahon worse, as it would open up lazger cracks A further recommendahon is to have our staff keep accurate records on the amount of makeup water used this season and the amount of water used to backwash the filters Considerahon should be given to mstallmg meters m the pipmg to accurately measure these pomts. We would ask Pubhc Works to assist us m havmg these meters mstalled. The Department bel~eves that could be a great demand for these publ~o-swimmmg facil~ties if there is a hot dry summer These pubhc faciliaes will become even more important if pnvate pools aze not allowed to be 511ed this summer We urge Public Works to consider allowmg us to fill and open Scott Carpenter pool for the summer. D. Public Outreach 1) Recommend that evemng or mght City workers, mcludmg pohce, fire, environmental enforcement staff be on the lookout for water spraymg onto streets near pazk areas 2) Recommend that PubLc Works estabhsh a telephone number for cit~zens to call if they see imgaUOn systems rumm~g E. Public Information ,a, We propose that signage be addressed m a couple of azeas 1 Park or fac~lities imgated by drtch water - s~gns need to be mstailed at entrances to, or m other strateg~c places (golf course clubhouse) wh~ch explams that the facility is imgated via non-potable ditch water 2 Mamtenance activiues - A reduction m water usage does not rei~eve us of the responsibility of performmg preventative mamtenance on imgation systems Staff regulazly needs to acuvate systems for a short penod of ume dunng the day to check for broken or out of ad~ustment heads. We anticipate that this type of work would occur daily somewhere m the system, and we would always have a mamtenance staff person m the pazk checkmg on these systems We env~sion that some type of temporary signage needs to accompany the mamtenance staff m the fieid wh~le they are workmg on systems 3 Signage developed for most of pazk areas that explam about the water restncuons and commumcates the impact of the lack of water to the landscape .-• t2
