HomeMy WebLinkAboutSnow Storage Information 01 16 2018The Lakes at Valley West Subdivision – Phase 5 and 6 Preliminary Plat Application Snow Storage Information Since the proposed woonerfs are a new concept in Bozeman, snow storage has been brought up as a concern for all phases of the project. Based on experience gained in the two snow plowing seasons that have occurred in Phases 1 and 2, it has been demonstrated that snow plowing and snow storage has been successful with the woonerf street sections. The Phase 5 and 6 of the project have a woonerf and a 10 foot wide snow storage easement, along lot frontages that are on the concrete border side of the woonerf. We have calculated the ratio of available snow storage width (for standard streets and woonerf) and the table below shows that the woonerf section has more snow storage, per width of plowed street than the 35-foot standard local section. If snow on one side of a standard 5 foot wide sidewalk is considered, the woonerf section has an equivalent snow storage, per width of plowed street/sidewalk, as the 31-foot standard local section. Below is a chart that has been prepared showing the snow storage areas in the woonerf area compared to standard street sections. Street type Full width half width Snow storage width Snow storage width per foot of street Half sidewalk width Half width street plus sidewalk Snow storage width per foot of street and half of sidewalk Woonerf 24 n/a 11 0.46 n/a n/a 0.46 31 foot local 31 15.5 8.5 0.55 2.5 18 0.47 35 foot local 35 17.5 6.5 0.37 2.5 20 0.33 37 foot local 37 18.5 5.5 0.30 2.5 21 0.26 * Note: the 37 foot wide local street was the city standard for many years and is functioning well in numerous areas of the community. To further address the concern regarding snow storage, the applicant is providing an area adjacent to the lake within the Phase 4 open space for snow storage. This is shown in the exhibit regarding snow storage. To date there has been adequate snow storage on site but this area is designated just in case additional snow storage is needed. It is anticipated that in the event of The Lakes at Valley West Subdivision – Phase 5 and 6 Preliminary Plat Application large and consecutive snow storms that the HOA snow plow contractor may utilize this defined area or haul the snow offsite to a leased snow storage site. Snow storage easements will be designated on the final plat. The figure below shows the areas of snow storage for the project. FIGURE NUMBER © PROJECT NO.DRAWN BY: DSGN. BY: APPR.
