I I I I I I I . I I I I I I I r I significantly more soil correction as a result of its proximity to the adjacent wellands and apparent damage resulting from excessive frost heaving over the years. This segment of slreet received the lowest PCI rating in the neighborhood and has one of the worst conditions in the City. Reconstruction of this segment of Hamline A venue would also impact the adjacent welland edges and cost significantly more than the typical neighborhood street. Very litlle assessable property footage lies adjacent to the roadway which would result in a high percentage of the cost being borne by the City. Vacation and removal of this street would result in additional traffic on Ingerson Road and Dunlap Streets. field tests completed this summer indicated that traffic on Dunlap Street approximately tripled while Ingerson Road wesl of Dunlap approximately doubled. Although these streets are anticipated to experience additional traffic, the total daily traffic on each will be well within standards for residential streets. The proposed improvements include regrading of Ihe old roadbed to a more natural state with a bituminous pedestrian trail between Tiller Lane and Ingerson Road and landscaping enhancements to blend in with the natural areas adjacent to the conidor. Street Widths This report has incorporated two proposed street widths within the project area. The City in the past has generally reconstructed streets to a 32 foot width where physically possible however numerous exceptions to this "standard" exist throughout the City. for example, the recenlly constructed Tiller Lane and Dunlap Street are both 30 feet wide. The 1999 Pavement Management Program Comprehensive Street Condition Review has identified slreets within the City based upon the functions they serve. The various widlhs proposed in this report respond to the different functions that are provided by each street as outlined below: State Aid/Collector Street: Ingerson Road, Hamline Avenue The main transportation conidor Ihrough the neighborhood from Lexington A venue to Highway 51 is provided by Ingerson Road and Hamline Avenue. These two roadways are designaled MnDOT Stale Aid routes and function as collector/through streets. The proposed width for these streets is 28 feet which allows for easy movement of two-way traffic with no vehicles parked on the street. MnDOT State Aid rules will require that the Cily pass a no parking resolution in order to meet MnDOT width standards. Local Street: Carlton Drive, Fernwood Street, Cannon Avenue These streets primarily serve local residents only and have average daily traffic (ADT) counts less than 500. The proposed width of 28 feet is adequate to provide for City maintenance vehicles, emergency vehicle access and two way traffic wilhout parking. When parked vehicles are present two-way traffic is .possible but requires drivers to pass at slow speeds. The City parking ordinance resullS in limited on street parking at any time of the year and virtually no overnight parking so two-way traffic should generally operale satisfactorily. The narrower width provides for less runoff, reduces construction and maintenance costs and provides a passive traffic calming effect which is generally desirable on local residential streets. 4
