6A - Public hearing and request for advisory recommendation on Valmont City Park Phase 1 parking lot~- ~, CITY OF BOULDER PARKS AND RECREATION ADVISORY BOARD AGENDA ITEM MEETING DATE: January 29. 2001 (Agenda Item Preparation Date: January 18, 2001 ) .~-- ~...- ~ ... AGENDA TITLE: Public heazing and request for advisory recommendation on ~, Valmont Ci Park Phase 1 arkm lot o tions. REQLTESTED BY: C7uis Dropinski, D'uector of Parks and Recreation Ken Ramsey, Superintendent of Parks Planning and Construction ' Kate Bernhazdt, Associate Parks Planner FISCAL IlbIPACT: $4.1 million was allocated in 1997 to complete nuhal park planning and design, required review processes, annexation, and to construct Phase 1 of the park and associated infrastructure. Approximately $3,600,000 is available to complete planning and construction of Phase 1. PURPOSE: The Boazd's advisory recommendation concerning the Phase 1 parkmg lot is requested at this meeting. In the December 18, 2000 Boazd meeting, it was agreed that the Valmont City Park Phase 1 and Wonderland Creek Pro~ect bid package would conhnue through the bidding process with the following changes through addendum: • the proposed Phase 1 parking lot, circular drive, and associated landscaping would be identified as a potential deletion from the total contract • no gradmg would occur in the azea currently identified as "ballfield" on the approved Site Review plan, however ttus azea of the site would be used to stockpile fill dirt from the channel excavation The Boazd requested that staff return in January with alternative plans for Phase 1 parking for an advisory recommendation on the preferred pazlung option. The Board's recommendation on Phase 1 parkuig is required at this meeting so that construction work for the Valmont City Park Phase 1 and Wonderland Creek pro~ect, mcluding the parking lot option that the Board selects, can proceed in February. The bids for this project are scheduled to be opened on January 30. In order to avoid construction and legal problems associated with the conditions of the City and Cline Trout Farm Agreement, and to meet construchon interface schedules for pnvate uhlity installahons AGENDA ITEM N Paee 1 withm the project, the work in this contract should be awazded by February 2. Addinonal issues about the Valmont City Park plans were discussed at the December 18 ~ meeting, however clear resoluhon of the parking lot location was the only issue that requued immediate direction from the Board in order to allow the construction contract to move forward on schedule. At the end of this memorandum, an update is provided on other elements of the pazk plan and on other issues discussed m past meetings including: • Location of Wonderland Greenways Trail and width of channel nahve landscape • Removal of uees • Prairie dogs • WIldhfe study • Construction of a portion of the bike racing track m Phase 1 • Athleric lighting BACKGROUND: The Board approved the Valmont City Park Phase 1 scope of work and budget, based on the approved Site Review Plan, m September of 1999. The construction documents were completed for the Park Phase 1 work, including the Public Work's Wonderland Creek project, in late December of 2000. In the December 18, 2000 meeting, members of the Board expressed concern about the proposed Phase I parking lot. Phase 1 parking options are presented below for your consideration and recommendation.

C: Valmont City Park Phase 1 and Wonderland Creek Construction Plan (December, 2000) showing parking options A, B, C, and D. D: Valmont City Park Phase 1 and Wonderiand Creek Construction Documents (December, 2000) Parking Lot As Shown on C~urent Plans (two sheets) OPTION A: PROVIDE PARKING ON 49~ STREET Proposal: Design and construct approximately 6301inear feet of 49`" Street, sidewalks, a cul-de-sac, a gravei fines trail connection to Sterling Drive, right-of-way and park landscaping, a screened structure for portable toilets, and requued public and prrvate utilities (water, sanitary sewer, storm drainage, elecuical and street hghhng). This option would provide 32 on-street pazking spaces. Note: Trees would need to be removed to construct 49`" Street Process: a) Delete proposed Airport entry road, Phase 1 parkmg lot, hghting, circle drive, all associated site furniture, signage, landscaping, and bid items from Valmont City Park Phase 1 and Wonderland Creek contract so that the remaining park and creek construction work could be contracted m ~ ~ AGENDA ITEM k Page 2 a.~ ~ ~ ~""' ,~ February. b) Submit Request for Parku-g Defenal to the Planning Department for review and approval. c) Complete design work and plans to delete 32 parkmg spaces from the Approved Site Review Transportation and Parking Plan and to provide required parking for Phase 1 along 49`" Street. Complete Minor Modification to Site Review application and process. d) Complete final design and engineenng plans for 49`" Street and all associated site improvements. e) Obtain Technical Plan review and approval. ~ Complete change order process to add work to contractor's total project. OPTION A: ROUGH ESTIl~IATE OF TINIE AND COSTS Planning and Design time: Added hme to construction contract: Engineering, design, pro~ect management: Construction: A Total: 3 to 6 months 3 months $ 44,000 $813.000 to 961 000 $ss~,ooo co $i,oos,a OPTION A PROS• • Initial conversations with Transportation staff mdicate general support for this option if all required processes are completed. • Provides required 32 spaces for Phase 1 park construction. • Provides a portion of the required park infrastructure with existmg public funds which , benefits Phase 1 park use and future public and private partnership development. • Cunent cost estimates indicate that there is available funding for this option. OPTION A CONS: • Access to and from 49`" Street and Valmont Road, a muior artenal, is not controlled with a lighted signal. Because of this, it is difficult to enter or exit the parksIIe at 49`" Street and Valmont, particularly during peak traffic times (before and after work/school). • The Ciry loses the opportumty to establish the main enuy road, signage, and landscaping for the Valmont City Park at Airport Road using existing public funds. The Airport Road entry road would provide a more safe vehicle and pedestrian access to the park because of the planned signal installation at that mtersection. • The City would lose the construction efficiencies and savings anticipated by coordu~atmg the Pubhc Works Installation of signals at Auport and Valmont with the AGENDA ITEM k Pa¢e 3 Pazks and Recreation installation of Airport Road and associated utilities. As with any change that occurs at the construction phase of a project, additional time and expenditures would be incurred for redesign. OPTION B: PROVIDE PHASE i PARKING LOT SOUTH AND EAST OF AIRPORT ENTRY ROAD Proposal: In addition to the Phase 1 proposed Airport entry road, design and construct 4501mear feet of Airport Road, sidewalks, nght-of-way landscaping, retaining walls, lighting, a parking lot, parking lot landscapmg, a concrete access trail to the Wonderland Tributary Trail, and required public and private utihties (water, storm drainage, elec[ric and street lighting). Install a screened structure for portable toilets and an accessible picmc table west of the open turf area This option would provide 30 to 32 parking spaces. Note: Trees would need to be removed to complete the construction of Airport Road entry into the site. Process a) Delete Phase 1 parking lot, hghting, circle dnve, all associated site funuture, signage, landscaping, and bid rtems from Valmont Ciry Park Phase 1 and Wonderland Creek contract so that the remauung park and creek construction work could be contracted m February. b-~ Sunilaz process to that wluch is outlined above for Option A. and design tune• time to consuuction contract. ig, design, project management for Airport Road and parking lot : design, pro~ect management Airport entry Phase 1 plans (funds expended 1998-2001) additional Auport Road and lot: Airport Road (Phase 1 plans) B Total: 3 to 6 months 3 months $ 27,000 $ 21,000 $279,351 to $330,142 $139.000 to 139 000 to ~ ,...~ ~ ...% ~ ..r AGENDA ITEM N Page 4 ,.~-~ OPTION B PROS: ~, • Initial conversations with Transportation staff indicate general support for this option if all required processes are completed. • Provides adequate spaces for Phase 1 park construction. • Provides the mam entry road to the park and park infrastructure with existmg public funds which benefits both Phase 1 park use and future public and private partnership development. Provides a main entry identity for the park. • Provides safe access, for vehicles and pedestrians, from Valmont Road to the new park at a signalized mtersection. • Cunent cost estimates indicate that there is available funding for this option. • Potentially this parking lot could be incorporated into the proposed Neighborhood Commercial development at a future date. OP'TION B CONS: • Places a designated park-user parking lot within the proposed Neighborhood Commercial Development azea. • All pedestrian traffic from the parking lot to the park must cross Airport Road to access the park facilities and trails. • Loss of construcnon investment if parking lot cammot be incorporated into Neighborhood Commercial Center and loss of investment for concrete walk connection to Wonderland Tributary Trazl. • As with any change that occurs at the construchon phase of a pro~ect, additional time "~ and expenditures would be mcurred for redesign. ~ OPTION C: NEGOTIATE USE OF NEAR-BY INDUSTRIAL OR OFFICE PARKING LOT FOR PHASE 1 PARKING REOUIREMENTS Proposal. Negotiate with adjacent property owner(s) to the west of the pazk to lease use of their parking lots for Valmont City Pazk Phase 1 park use Install a screened structure for portable toilets and an accessible picnic table west of the open turf. The negohations would need to identify 32 spaces, available from dawn to dusk, seven days a week, to serve the initial park development. Process: a) Delete proposed Airport entry road, Phase 1 parking lot, lighting, circle drive, all associated site furniture, signage, landscaping, and bid items from Valmont City Park Phase 1 and Wonderland Creek contract so that the remaining park and creek construchon work could be contracted in February. b) Submit Request for Parku-g Deferment to the Planning Department for review and approval. c) Work with Real Estate and Legal staff to initiate discussions with property owner(s) west of the park. d) If acceptable agreement can be arranged, prepare legal documents for v" lease ~ AGENDA ITEM ~ Page 5 e) Obtain approval of the parking lease agreement from Transportation Staff, Parks and Recreation Advisory Board, Planning Board, and City Council. ~ Complete Minor Modification to Srte Review process. g) If lease conditions require redesign and unprovements to the leased parking lot or addinonal access walks and site improvements, complete necessary design and engmeenng. h) Obtain Technical Plan review and approval i) Prepare Change Order for contractor. time: and design time: tune to construction contract: 3 to 6 months plus 1 to 3 months 1 to 3 months (possibly legal) $6,000 to $12,000 plus ieering and design including staff time (future costs) to be deternuned Construcnon (future costs). to be determined OPTION C PROS: • Provides required 32 spaces for Phase 1 at lower uutial cost than constructing parking ~ lot an site. Provides potentially more efficient use of existing parkuig facilities, assummg that the industrial or office complexes are not using their parkuig facIlities to full capacity. Reserves additional space on the park for other park uses. Current cost estimates indicate that there is construction funding available for this option. OPTION C CONS: • Risk: Anticipated non-programmed recreational uses* for the park Phase 1, mcludmg the Wonderland Creek tributary trail, will occur dawn to dusk, workdays and weekends. The Parks and Recreation Department would have to procure parkmg spaces available at all times of the day throughout the year. 11us may be difficult given the assumption that most industnal development has been designed to provide the muumum AGENDA ITEM ~l Page 6 ~ ~ '"'ye ~ ,„, required parking spaces for anticipated employee and customer needs, generally y,,,,, throughout the work day. If spaces could be procured, it is likely that the lease term would be hmited to allow the properry owner redevelopment options for theu property, which in turn provides no guarantee that the required parking to serve Phase 1 and the park would continue to be available on a permanent basis. The industrial properties due west and southwest of the park are currendy under consideration for Mixed Use Industrial land use classification in the Boulder Valley Comprehensive Plan. If ttus use is approved, residenual development may be added to the industrial complexes which would additionally lunit the number of pazku-g spaces available throughout the day. See below: Use of adjacent industrial parking included in the Valmont City Park Site Review for anticipated programmed activity parking. • Transportation staff is generally not supportive of this oprion unnl appropriate measures are taken to assure that adequate permanent parking spaces are provided at all potential park use tunes in appropriate proximity to the park use areas. Safe pedesuian access must be provided from the parking facility to the pazk, wluch may require additional design and construction funds. • If negotiations to lease parking spaces are unsuccessful over a period of time (6 months), staff will need to return to the Board to select an appropnate parldng option for Phase 1 and to proceed with the design, review, and construction of that option at a later date. • On going lease costs would need to be addressed in future CIP programs or through parks maintenance budgets. ""~ • As with any change that occurs at the construction phase of a pro~ect, additional time ~"" and expenditures would be incurred for redesign * Valmont City Pazk Phase 1 and Wonderland Trail uses: General un-programmed recreational uses anticipated for the Valmont City Park Phase 1 development (12 to 13 acres) and Wonderland Cseek Trail include: walking, running, bicycling, skating, youth soccer practice, pick-up social ball games, picnics, frisbee (individual and group), pubhc and private school special events, day care uses, wallang and trailhead access to the Wonderland trail, footbail pracnce, kite flying, dog walking, family and group picnics, cross country skiing, and other uses. Note: Use of Adiacent Industrial Site Parkuie is Included in the Site Review Plans: The initial planning processes for the Valmont City Pazk identified a cleaz intention to use adjacent mdustrial site parlung for specific programmed park uses such as the proposed b~ke races and special events. This intenrion is addressed in the Approved Valmont City Park Site Review Transportahon and Parking Plans. It is anucipated that the City or public and private partnership development partners will be successful in negotiating use of adjacent industrial parking for programmed activihes and special events because a specific time and volume of parkmg use can be identified which allows the City and the neighboring property owner to create an agreement for use of the private parking lots at specific tunes when the property owner does not need the parking for theu business. ~''., ~ AGENDA I1'EM N Pape 7 OPTION D: PARKING LOT AND CIIiCLE DRIVE AS SHOWN ON CURRENT CONSTRUCTION PLANS Proposal: Provide a 32- car parking lot, a circular dnve for bus and van pazking or drop- off uses, a landscaped island, lightmg, walks, sitting areas, picnic facility, bike parking, screened shelter for restrooms, requued landscaping, public and pnvate utilities, and associated trail connections. (See Attachment D) Note: Trees would need to be removed to construct Airport Road, the pazking lot, and the circle dnve. Design Intention: The approved Site Review plans tdentify community and family uses for the south side of the lmoll including landscaping, paths, overlook sitting areas, picnic areas, and on the lower portion of the hill, a children's play ground. The parking lot, one way circular dnve, and mterior development of the 95-foot wide island were designed to accommodate those future uses as well as Phase 1 uses. In order to create a more pedestrian scale and use for the azea, the circle drive was designed as a one way road limited to small bus and van parking and drop- off only. The circle drive would be paved with colored concrete brick pavers. The island contained more detailed garden-like landscaping, bnck paths, sitting areas, an accessible picmc table, and a screened restroom facihry. This type of development would not be necessary if Parkmg Lot Options A, B, or C are selected and if the long term plans for public access to the hillside differ from the Concept and Site Review plans. Process: a) Design, engineering, and technical plan review has been completed. b) Constmcnon is mcluded within the current bid package. and design tune: Completed Added time to construchon contract: None ring, design, pro~ect management: lot and island (funds expended 1998-2001): $ 68,000 ring, design, project management Road entry (funds expended 1998-2001) $ 21,000 struchon of 32-car parldng lot ($260,400) circle drive and island development ($196,099): $456,500 Auport Road entry 139 000 D Total: ~ "', ~ '""R AGENDA ITEM N Page S r- OPTION D PROS: .... • Design and engineering work has been completed. • Provides 32 required parking spaces for Phase 1. • Provides small bus and van drop-off and parking along with emergency access. • Provides social use area with sitting, picnicking, landscaping, and restroom facilities for Phase 1 and future development, if park is developed as shown on Concept and Site Review Plans. OPTION D CONS: • Location of Parkuig Lot: Concem has been expressed about the location of the parldng lot relative to Valmont Road, the entry drive, and the knoll. The parking lot is located 44' south of Valmont to allow space for right of way landscapmg, the bike racing track, a public sidewalk, and required pazking lot landscape screening. • Gradine for Parking Lot and Circle Drive: Concern has been expressed about grading this area of original site topography for the parking lot. Distance from the top of the knoll to the Valmont Road south curb is 182'. The topography creates a short plateau in tlus area north of the l~oll. The proposed right-of-way landscape along Valmont, sidewalk, bike race track, parking lot landscaping, pazking lot, and sidewalk would occupy 119' of that 182' length or roughly 65 % of the total distance, Valmont curb to top of knoll. In order to place the parking lot into this area, both cut and fill will be required. The majority of the north ,'~~ curb face for the parking lot would require fill between 0" and 12". The centerlme of the parking lot would require cuts of between 0" and 1' 6". The southwestern portion of the parking lot requires cuts of 1' to 3'. The southeastem portion of the parkmg lot requires cuts of 1' to 5' . The primary area of cut is the southeastem portion of the lot and the entry drive to the lot. The one way circle drive to the west of the parking lot is generally set at grade. • Removal of exisrin~ Concem has been expressed about removal of trees. Most of the trees to be removed ' are volunteer Siberian Elms or trees which are currently in poor condrtion from overcrowding, lack of water, and lack of care. Some larger specunen trees that are m good condition, both Siberian Elm and other species, have been preserved in the current Phase 1 plans for roads and pazking. No construction will be allowed beyond the Phase i construction limit line, which preserves all plant material on the top and on the south side of the knoll. A representauve of the Ciry Forester has provided an evaluation of the Siberian Elms on the pazksite. See Attactunent E. ANALYSIS: The process required to change the construction plans at this point is summarized above along with the pros and cons of each solution. Options A, B, and C will require staff and consultant work over the next 3 to 6 months which will have some affect on staff's and/or the consultant's availability to move forward with other projects ~ ~ AGENDA ITEM N Pa¢e 9 PUBLIC PROCESS: Public meetings have been held from January, 1997 through the present regarding Valmont ~ Ciry Park. The current Phase 1 construction documents reflects these meetings. A summary of the past pubhc process for the Valmont City Park is shown in Attachment F. 11us public hearing is provided to obtain the Board's direcnon concenung the parking lot. With the Board's d'uection on this issue, staff will award the contract and work on Wonderland Creek and Valmont City Park Phase 1 will proceed. BOARD ACTION REOUESTED: Staff requests that the Board provide an advisory recommendation on the prefened parking lot option. A recommendation is needed at tlus rime so that construction can proceed according to schedule. This will facilitate work scheduled for the Clme trout farm lines and the pro~ect interface with work scheduled for private utility installations. OTHER ISSUES DISCUSSED IN DECEMBER 18 MEETING AND GENERAL UPDATE: Location of Wonderland Greenways Trail and width of channel native landscape• Annie Noble, the Interim Greenways Coordinator has provided an Item for Information in this board packet. Removal of Trees ~ Existmg trees will need to be removed for the following development. -~ 1. Right of way landscaping south side of Valmont 2. Right of way sidewalk and bike racing track south side of Valmont 3. Undergrounding private utilities withm the right of way south side of Valmont 4. Construction of Wonderland Channel 5. Extension of Auport Road into the site 6 Construction of 49`" Street (Option A) 7. Construchon of parlang lot south and east of Airport/Valmont (Option B) 8. Construcrion of parldng lot and circle drne as shown on current Phase 1 plans The majority of the trees to be removed are Siberian Elm volunteers or trees wluch are not in good condition due to crowding and lack of care. These trees vary m size and matunty Siberian Elm is not a destred pubhc park tree species and rt is not included in the City of Boulder Approved Street Tree list. The Ciry Forestry staff has provided an evaluahon of the Siberian Elm trees at Valmont City Park m Attachment E. Large specimen uees which are in good conditions including Siberian Elm, Honey Locust, Cottonwood, and Plum are bemg preserved m the Phase 1 plans. Prauie does There are approximately 15 praine dogs within the Wonderland Creek and Valmont ,,, AGENDA I1'EM 1/ Paee 10 ~ Ciry Park Phase 1 construction area. In comphance with all current City of Boulder w..~ Ordinances and the City of Boulder Interdepartmental Prairie Dog Policy, prairie dogs are being relocated by qualified wildlife staff and organizations from the pazk Phase 1 and Wonderland Creek construction area to suitable prairie dog habitat locations on City of Boulder Open Space Property. Wildhfe Studv: Stephen Jones, an environmental consuitant, has been hired to complete a wildhfe study for the pazksite, including specific focus on prairie dog issues. His report will be available at the end of February. The initial portion of his work may be available for the February 13 study session. Construction of a portion of the bike racing track in Phase 1: As a reminder, the board approved construction of approxunately 820 to 9001inear feet of the 21.75 foot wide bike racing track as part of Phase 1, if fundmg is available. The design of this track has been included as an Add Alternate in the Construction Documents Athlehc Field Lighting• The approved Valmont Ciry Park Concept Plan and Site Review Plans show six lighted ballfields or muln-use athletic fields on the park property south of Valmont. Concem has been expressed that the ballfield lighting would negatively affect: a) the neighbors to the north of the park b) the wildlife area associated with the ditches within the park north of Valmont Road ~~ c) the proposed native planting area with potential wildlife habitat along the ~ Wonderland Creek Channel The proposed ballfield/athlenc fields are 240 feet from the property hne and 350 feet from the Parkside Village residential units on the north side of Valmont. During the concept planning community and neighborhood meetings, the neighbors did not express concem over ttte proposed hghted athletic fields Over the past 10 yeazs, ballfield lighting systems have evolved to meet increasingly more restrictive local lighting ordinances. Through the development of "cut off" light fixtures, current ballfield hghtmg is directed down onto the fields with minimal lateral glare or spillover light beyond the fields. It is anticipated should lighted athletic fields be built at Valmont Ciry Park, they would meet current City of Boulder light spillover standards within 50 feet or less of the outfield fencing ATTAC~~IENTS: ~ Attachment A.

Siberian elm is a tugh maintenance tree species There are several large specimens on the Valmont Park site that should be considered for inclusion in the park plan because they aze established trees, ia good conditio~ aze structurally intact and provide many environmentat and aesthetic benefits to the community After evaluating the site however, there are numerous Siberian elm "clumps" and severai lazger diameter elms for wluch the Pazks & Recreation ~ Forestry Section has recommended removal. These trees should be replaced with a diversity of other tree species to promote a more "pest &ee", healthy tree population The reasons for our decision aze as follows Dutch elm disease (DED) is a fatal fungal disease that is responsible for the death of millions of American elms across the country Siberian elms aze resistant to Dutch elm disease. They will not die &om the disease but can become infected and act as "carriers" and have pocicets of the fungus within their wood These "carriers" cannot be identified and targeted for praning or removal because they often do not show symptoms of the disease Sibenan elms over 8" diameter harbor the European elm bark beetles that carry DED If beetles colonize the infected pockets of wood they will exit carrying the fungus to nearby healthy elm trees Siberian elms grow very fast, but because of ttus are weak wooded and tend to have poor structure The tight crotch angles and included bark (bark enclosed between branches with narrow angles forming a wedge and creating a structurally weak point in the uee) increase the likelihood that these trees v~nll fail during wind or snow storms. Our local Front Range Urban Foresuy Council rates Siberian elm as a high hazard species because of these defects. As sucl~ the pruning costs associated with Siberian elms tend to be considerably higher per prune and these uees must be pruned more often The multi-stem "ciumps" over time will grow together and would require multiple thinning operations and mdividual uees would require stcuctural prumng every few yeazs. ,~^ ~.. JOF2 Siberian elms are not on the approved street uee list within the City of Boulder Design and Cons~uction Staadazds (Revised November 16, 2000). They aze classified as an "undesirable" uee species because of the reasons listed here. '""~ _ ~ Siberian elms have infestations of elm leaf beede that in some years can completely defoliate the trees. The Forestry Section receives complaints each year pertaining to Siberian elm trees in street righu-of-way because the insects enter homes by the hundreds in winter months and aze considered a nuisance. This is aa iasect t6at the Forestry Section does not currently chemically tceat If the large numbec of Siberian elm clumps is retained az the Valmont Pazk site however, chemical usage may increase if the elm leaf beetle population threatens the life of the trees. Staff's objective however, is to reduce the need for chemical treatmem of insects by reducing the species prone to insects or disease. Siberian elms are not well adapted to the temperature extremes so common in Colorado AIthough these trees are native to a very cold region of the world, it gets cold and stays cold there. They do not have the hardiness to siuvive extreme temperature fluctuations In 1991 in Boulder aloae, 2591arge Siberian elms were lost as a result of the "Halloween freeze" on city properry. There are no estimates of Siberian elms lost on private properry but the damage was considerable • Siberian elms tend to have heavy annual seed crops but every few yeazs is exceptionally heavy Their seeds also have a high gemunation rate and therefore create a nuisance for the horticulturists who are trying to maintain shrub or annual flowerbeds azound any Siberian elm uees. ^"~ Several cities and counties along the Front Range have ordinances aga~nst having Siberian elm firewood within city limits because it might contain disease-carrymg beetles. In Boulder, the Forestry Section has required property owners to remove eim firewood based upon Chapter 6-6 -Z (Removal of Dead, Diseased or Dangerous Trees) of the City Ordinance z O~ 2 T ATTACHMENT F Valmont City Park Public Process Summary /"°' (January 1,1997 to January 1, 2001) ~. ~ Public Mcetin¢s: Spring, 1997: Noble Park Neighborhood Association Apiil, 1997• Commumty Review Group Public Review July 9 and 19, 1997: Two commumty des~gn review mceUngs Pazks and Recreauon Advisorv Board: Public Review Meetinvs (23 meetinas totall • Apn1,1997: Inforn~al approval: Valmont City Pazk Planning Goals and Worlang Assumphons • August, 1997: Approval of concept plaa including park program directives • Decem6er, 1997 Approval of revised concept plan for CEAP (Community and Envimnmental Assessmem) submittal • March, 1998: Approval of CEAP and Final Concept Plan • November, 1998• Infornial approval of proposed Site Review Plans • February , 1999• Approval Wonderlaud Creek Chanael Concept Plan and request tl~at staff add cross country sla uail extension to plans • June, 1999: Informal appmval of proposed Pubhc and Private PaRaerslvp Pracess and Pohcy • August, 1999: Approval of desigoation of private easements • September, 1999: Apgroval af Valmo~ Criy Park Phase 1 scope af wock and budget • June, 2000.
