development to provide a connection for future development to the east. There are five proposed cul-de -sacs which intersect with either Street A or Street B. While staff recommends providing a street stub to the eastern property line for future street extension, the developer should demonstrate how the street would service the adjacent parcel. There is a large wetland complex east of the proposed street stub that would limit future alignment options. Additionally, the street abuts the St. Paul Water Utility property, which contains an existing large diameter water main. This may cause conflicts with the sanitary sewer and water main stubs as well as the roadway. The water k. utility is currently reviewing the proposal for possible impacts. Should the street be extended to the east property line, the applicant will be required to provide a permanent easement for a cul-de -sac to be constructed until the street is extended Signage should also be located at the street terminus indicating the future extension of the street. Street A is proposed as a large loop in the southern half of the development. While this section has two access points, they form the same intersection and create a situation similar to a long cul -de -sac. Staff has evaluated other alignment options, however it appears that these would cause additional wetland impacts. Staff is reviewing this issue with the Public Safety Department and the Centennial Lakes Fire Department to determine if there are any access concerns with the proposed layout. Staff is also recommending that the . applicant evaluate a possible street stub alignment to the south of the development in the approximate location of Street G. This would allow for a future connection with East Holly Drive. The 2001 Transportation Plan identifies East Holly Drive as a Minor Collector and proposes its future connection with Holly Drive to the west and Ash Street (County Road J) to the south. While these projects are not planned in the near term, it would be practical to reserve the option to connect this subdivision. to Holly Drive in the future.. Grading and Drainage. A grading plan has been submitted and is subject to the review and approval of the City Engineer. A Rice Creek Watershed District (RCWD) Land Development Permit is also required . The ..house .pad on Lot.. 9, Block 9 . should be . reoriented to provide a more suitable building pad. The plan does not identify the Normal or High Water Level for wetlands No. 12 and No. 13. Mitigation sites are proposed to be fenced off after grading is completed to restrict construction traffic. According to the plans, there are no provisions for bringing materials onto the site or hauling off the site. Utilities. A preliminary utility plan has been submitted and is subject to the review and approval of the City Engineer. Sanitary Sewer is proposed to be extended to the site from its existing location in Sherman Lake Road, north of Birch Street. Water will be provided by connection to the existing 16" trunk water main lying adjacent to the property on the south side of Birch Street. The water main is proposed to be looped back to the system by crossing Birch Street at Pheasant Hills Drive. Stoneybrook Page 4
