. . . INGERSON PROJECT REVIEW GROUP RECOMMENDA TlONS Street Classes Based upon Average Daily Traffic (ADT) Volume: Access Street 0-250 cars Subcollector 250-1,000 cars Collector 1,000-3,000 cars16 Accepting the above classification, the streets within the Ingerson Project would be classified as 17 subcollectors or access streets. STREET WIDTHS Review GrouD Recommendations: It is the recommendation ofthe majority of Review Group members that the current widths of the project roadways be maintained. The initial BRW feasibility report for the Ingerson Project proposed the widening ofthe current street widths of approximately 24' - 28' to approximately 32'. The majority of Review Group members are opposed to the widening of any streets within the Ingerson Project from their existing widths. From the standpoint of safety, traffic, water quality and stormwater management, numerous articles have been written regarding the width of a neighborhood street. From a safety and traffic management aspect, the American Society of Civil Engineers, National Association of Home Builders and the Urban Land Institute have made the following observations and comments: The width of a street should be based upon both the volume and type of expected traffic and the amount of on-street parking that will be generated as well as upon the place of the street in the street hierarchy (access street, subcollector, collector). Designers should select the minimum width that will reasonably satisfy all realistic needs, thereby minimizing construction and average annual maintenance costs. The tendency of many communities to equate wider streets with better streets and to design traffic and parking lanes as though the street were a "micro freeway" is a highly questionable practice. To discourage excessive speeds, streets should.. .not be designed to be wider than is necessary... [because ] [wider lanes] tend to encourage higher-speed driving. A wide access street also lacks the more intimate scale that otherwise makes it an attractive setting for housing. 16 Residential Streets, supra. 17 An average daily traffic volume and traffic speed study was conducted by the Ramsey County Sheriffs Department on behalf of the City of Arden Hills on Ingerson Road on August 30,1999. The results ofthe study indicated that the ADT for Ingerson Road was 559 vehicles. 11 August 17. 2000
