INGERSON PROJECT REVIEW GROUP RECOMMENDATIONS . District, from a water quality standpoint, the roadway options are as follows: . Worst: (32' wide, full storm sewer, curb/gutter, regional ponds) Increased volume, increased rate, increased water quality treatment requirements, full ponding necessary, most costly. . Better: (28' wide, fuJl storm sewer, curb/gutter, regional ponds) Maintained volume, increased rate, increased water quality treatment requirements, full ponding necessary, slightly less costly. . Best: (26' wide, needed stormsewer, surmountable curb, rain gardens) Maintained volume, decreased rate, drastically reduced water quality treatment requirements, elimination of regional ponds, significant cost savings32 From a water quality standpoint, the Rice Creek Watershed District would like to see Arden Hills maintain the existing street widths within the Ingerson Project and thereby reduce the amount of impervious surface that contributes to stormwater runoff/pollution.33 The Review Group learned that neither the surrounding City of Golden Valley nor Maplewood increase street width during their PMP projects. Maplewood's streets are primarily 28' wide with some streets as low as 20' wide.34 . One of the arguments to increasing the street width within the Ingerson Project was to "standardize" the widths of all Arden Hills streets. In view oftbe fact that rigid standards as to street width have not been used in the past, the Review Group found this argument unconvincing. Although some streets such as Stowe Ave. were reconstructed at 32', other Arden HiJls streets have been reconstructed at 24' (Pascal Ave.), 28' (Oak Ave.) and 30' (Dunlap and portions of Tiller Ave.). Therefore, even if any of the streets within the Ingerson Project were increased from 28' to 32', as proposed in the BRW feasibility report, the streets within Arden Hills still would not be "standardized." One Review Group member recommended that Hamline Ave. be rebuilt to MSA standards. MSA representatives have advised that it is common for cities to request variances in street widths for MSA designated roadways and that such variances are often granted. Greg Brown acknowledges the accuracy ofthis statement. There have not been any significant changes within the Ingerson neighborhood (e.g. increase of traffic, additional roadways added to the neighborhood, additional homes added to the neighborhood, etc.) since the neighborhood streets were built in the 1950s. County and City snowplows have navigated the roadways successfully for over 40 years. To the Review Group's knowledge, thcre have not been any traffic or pedestrian accidents within the ncighborhood that could be contributed to the dcsign of the current street width. However, there have been resident complaints regarding the speed some motorist travel on the streets within the Ingerson Project. e 32 April 4, 2000 Review Group Meeting. 33 Id. 34 City of Golden Valley web site and May 2,2000 Review Group Meeting. 15 August 17. 2000
