The City should review MnDOT plans and schedules for utility improvements as pan their T.H. <br />I- improvement project. As noted in our previous review comments the sanitary sewer between T.H. 12 and the <br />railroad tracks will need to be upgraded to serve the ultimate development of the Stoneba> site. The plans should <br />I entity |;c\v sanity service will be provided to Outlot A. The sanitary sewer manhole details should be rc vis<*d to <br />include .an Infi-Shield exterior sealing system or approved equal. <br />2. \\ atcr Maiii: Hydrants should be installed at all high points in the system. Stainless steel bolts shall be used on all <br />h>drants. All water mam bolls shall be stainless steel or Cor-Blue i-bolts with protected caps. All water main <br />installation shall be in accordance with City standards. <br />T uTa^vv P'an set docs not show relocating the downstream pipe from the ponding area north of <br />T.H. 12. Wc recommend the pond outlet pipe be relocated westerly to align with the cxistine nordt/south ditch along <br />the vvest side of the golf dome. As noted in our previous letter, the golf dene e xperiences parking lot and building <br />Bood ng during heavy ram events The realignment of the pond discharge will eliminate two bends in tlie ditch and <br />divert storm water away from the golf dome parking lot. A minimum of 2-fcet of freeboard should be provided <br />etwten a.i basement elevations and pond high water levels. Grading plans should include ICO-yeai high water <br />elevations ano proposed emergency overBow c!evat.ons and locations for all wetlands and ponding areas A <br />drainage a.'ca map. storm sewer and ponding calculations should be submitted for our review Erosion control pbn <br />comments will follow under separate cover. The wetland delineation report should be submitted for review Final <br />plans should be submitted to the Minnehaha Creek Watershed District (MCWD) for th.eir review and approval. <br />Streets/Trails: We recommend a rr.inimum radius of 500-feet for all horizontal curves on Xelley Parkway to <br />provide an added .measure of safety and improve sight distance. Plan.x should include venical curve information <br />The r.glK-of-way width shown along the e.-vstorlv 500-feet of Kelley Parkway is inadequate for the proposed suect <br />i-oign. The right of way width should be increased to provide a minimum of I5-fect behind the back of curb. A <br />ccni-r non bour.^ Icfi turn hrt and southbound ri^ht turn lane should be consirucied on Willow Drive as part of (his <br />project. The trail shown along Willow Drive north of Kelley Parkway should be realigned to intersect with Kelley <br />Parkway at the intirsection with Willow Drive. The plans show a trail and sidewalk adjacent to each other along the <br />w-ii n It'S unclear why a trail and side walk are necessary. The trail along <br />f I constructed to T.H. 12 as pan of this project -nS^designguidelin! <br />for Kelley Parkway on Sheet C. 2 shows a 5-f.^t sidewalk directly behind the curb. The City should review and <br />comiTKnt whether this is adequate tor snow s:ctage. The same design guideline shows a 5 -foot "trail" on the other <br />side of the street, all trails should be constructed to a minimum width of 8-fcet. A geotechnical report, R-value <br />recommenJatio.i and pavement design should be provided for review. <br />4. <br />2335 West Highway 36 • St. Paul, MN 55113 • 651-636-4600 • Fax: 651-636-1311
