S.0 PROJECT IMPACTS �_ 1 Traffic generation (Source: Institute of Traffic Engineers — Traffic Generation Manual) is estimated to be from 7 to 11 vehicle trips per dwellingunit per day, or a total of 21 to 33 additional trips entering or leaving the site during a given 24-hour period. While Acorn Road is narrower than most other streets in Roseville, the City Engineer has affirmed that Acorn Road is able to handle the same volume of vehicle traffic as any other two-lane road. The additional vehicle trips will not cause the total volume of vehicle traffic to exceed the current capacity Acorn Road. 5, � The City has adequate sanitary sewer, storm water, and water mains in place to support the development project. Prior to Final Development �'Ian approval, the Public Works Department and the Rice Creek Watershed must review and approve all of these detailed plans. �.� STAFF COMMENTS AND FINDINGS: �r. ! Section 1103.021 C(Minimum Roadway Standards) of the City Code indicates that no cul-de-sac is required in the absence of a looped road system if a street is less than 200 feet in length; because the proposed private road is only about 175 feet long, the City does not require the provision of a cul-de-sac. b,� Section 110�,02A (SubdivisionDesign Standards) of the City Code requires that publicly-dedicated cul-de-sacs have a minimum right-of-way (ROW) radius of 60 feet; this development will require a PUD because the radius of the private easement for the proposed cul-de-sac is only 42 feet. fi_3 Section 1103.02A further requires that a publicly-dedicated local street have a minimum ROW of 60 feet; again, this development requires a PLTU because the private easement of the proposed street is only 51 feet. 6, � Emergency vehicles will still be able to utilize the proposed private road and cul-de-sac, but the City will not assume ownership of the infrastructure because of its substandard dimensions. �,, 5 Rezoning the property to PUD to accommodate the proposed development is consistent with the Comprehensive Plan, which guides this area for low-density residential uses, because the proposed development will remain under the density threshold of 4-units-per- acre. �.�a The residential building setbacks are acceptable as proposed. The northern property line of Lots 3 and 4 and the southern property line of Lots 1 and 2 abut the interior side yards of the adj acent properties; planning staff would, therefore, support 10-foot principal structure setbacks from each of these property lines so as not to impose a higher standard on the proposed new lots than is required of the existing lots. Since the western property line of Lots 2 and 3 abut the rear yard of the properties to the west, it appropriate to maintain the 30-foot setback from those property lines as proposed. �. � The proposed preliminary plat indicates 10-foot drainage/utility easements centered on P�'3766�RCA�GeneralCancept{092546} I.doc Page 4 of 7
