INGERSON PROJECT REVIEW GROUP RECOMMENDATIONS Development tends to alter the flow of runoff during heavy rains. When you have cities that are growing quickly, the runoff patterns can be altered very easily by things like parking lots, driveways, sidewalks, streets and landscaping. 13 . As stated by numerous Arden Hills' residents at the January 10, 2000 Council meeting, one of the reasons why the residents moved to the Ingerson neighborhood was because of its aesthetic beauty. It is the recommendation of a majority of the Review Group members that the Ingerson Project not disturb the current design and makeup of the Ingerson neighborhood. STREET CLASSIFICATION SYSTEM In order to determine the types of improvements and the type of standards that should be imposed and incorporated into a street, including the streets within the Ingerson Project, one needs to determine how streets are classified. 14 The American Society of Civil Engineers, National Association of Home Builders and The Urban Land Institute provide the following street classification systemJ5 Arterial. An arterial is a high-volume street that should have no residences on it. Its function is to conduct traffic between communities and activity centers and to connect communities to major state and interstate highways. (e.g. Snelling Avenue) Collector. As the principal traffic artery within residential or commercial areas, the collector carries relatively high traffic volumes and conveys traffic from arterial streets to lower-order . streets. Its function is to promote the free flow of traffic; as such, communities should not encourage parking or residences along a collector. The collector's secondary function is to serve abutting land uses. A collector street may also accommodate public transit such as buses. (e.g. Lexington and "main" Hamline [not residential HamlineJ)_ Subcollector. The subcollector provides passage to access streets and conveys traffic to collectors. Like the access street, the subcollector provides frontage and access to residential lots but also carries some through traffic to lower-order (access) streets. The subcollector is a relatively low-volume street. (e.g. residential Hamline, Ingerson Road, Tiller Lane) Access Street. The access street is designed to conduct traffic between dwelling units and higher-order streets. As the lowest-order streets in the hierarchy, the access street usually carries no through traffic and includes short streets, cul-de-sacs, and courts. (e.g. Cannon., Carlton Ave., Dunlap Ave., Fernwood Ave., Femwood Ct., Ingerson Ct.) 13 Flood Insurance, STAR, July 29, 2000. 14 Residential Streets, supra. IS The MN Local Road Research Board recommends that streets no longer be referred to as local, collector or arterial but rather living, mixed or traffic purpose streets. Such designations classifY streets according to their intended purposes which then "dictates the most appropriate traffic calming deviccs to implement." Effective Traffic Calm in f.!
