J?lari,~fold Pond Final IVa! Re'view ,hdy 22, 2005 UtiIities: 'l'his development is proposed to be se~iced with mu~ofp~l sewer and water and c(mstruction plans haw been submittal. Staff offers the following comments to the submi~ed construction plans: ]. Additional watennain valves should be placed ~t the following locations: w~st leg of 160th lane and Iodine Street~ west leg o~ 162~d Avenue and 161~t L~ne~ e~st leg of LitM~ Court m~d ]61st Lane~ east leg of 162~ Lane and Lit~um Street~ East leg of J~ite Street and 161~t Lane. 2. Addfffonal hydrants and valves should be added to the 16-inch wate~ain. 3. Valves need to be clustered as shown on the Ci~ detail WAT-5 4. The fore,main should be raised or lowered on 160th Lane to avoid conflicts with sanga~ sewer laterals. 5. Th.c profile of the 16-inch wate~ain should include the adjacent and crossing sto~ s~wer. It is anticipated that insulation will need to be added be~een the wate~ain and storm sewer at station 110+00. 6. The lift station will discharge t~ough a forcemain into the gaviW sewer located at the intersection of TH 47 and 156th Lane. In mm t~s Maviw system flows to the lie station locat~d near 155th Lane b~tween ~pton and Ju~te Streets. That lift station discharges to the graviW sani~ sewer located east of the Alp~e Drive 'medical clinic. An engineering analysis of this system must confirm the adequacy of sewer capacities. 7. All storm sewer pipe shall be reinforced concrete pipe. Park Dedication and Trails: The preliminary plat was reviewed by the Park and Recreation Commission at their June 9, 2005 meeting, and recommended a cash payment to satisfy park and trail fees for the site. A trail is shown on the east side of Highway 47 up to 160th Lane where it turns back into the plat, and returns to Highway 47 at the northern boundary of the plat. This alignment was acceptable to the Park and Recreation Commission. Some revisions are required to the plat subnfittal to bring the trail completely to the northern property boundary. City trail policy requires a 1 O-foot trail. The Commission also recommended that an east-west easement be obtained to provide for a trail connection to the east. There is a large wetland on the eastern side of the plat that makes such a connection difficult. As a result of the Park Commission meeting, the City Council authorized staffto begin the design process to construct a below-grade crossing of Highway 47 at the no~hcrn portion of your plat. Staff will be working with you to coordinate grading and other site work with this project. For park dedication fees, a total of $202,400.00 ($2,200.00 X 92 lots) is required prior to release of the final plat for recording. For Trail Fees, a total of $50,600.00, ($550.00 X 92 lots) must be paid prior to release of the final plat for recording. Sanitary Sewer and Water Trunk Fees: The City has established a sanitary sewer and water trunk Jbe that must be paid prior to release of the final plat for recording. A total of $272,504.00 ($2,962.00 X 92 lots)
