-------- ---------- ARDEN HILLS CITY COUNCIL - NOVEMBER 8,1999 11 Cannon Avenue, Carlton Drive, Femwood Road, and Femwood Court. He noted that Tiller Lane . was not included in the project. Additionally, although Hamline Avenue North had been included in the report, it would be an expensive roadway to include in the project. Mr. Brown stated that the improvements to these streets would include reconstruction of the roadways, concrete curb and gutter, storm sewer and pavement subdrainage systems. The only deviation from past projects would be the proposed width deviation. Mr. Brown indicated that the costs included in the report reflect the proposed new width standards. Adding four feet of width to a roadway would add approximately 18 to 20 dollars per foot to the project. He noted that Tiller Lane and Dunlap Street were both constructed to 30 feet and he was not sure why this had been done. Councilmember Malone confirmed that the street widths were measured curb to curb. He indicated that he could not recall a decision to make Tiller Lane and Dunlap Street narrower than the standard. Mr. Brown stated that the measurements had been face to face. Mr. Brown stated that the project would include storm sewer and the issue to determine with this work was whether or not to include ponding. Because ofthe topography of the area, the best location for a pond would be west of Hamline A venue. In order to facilitate proper drainage, a large diameter pipe would have to be used. It may be possible to utilize a pipe with a shorter life expectancy and smaller diameter, however, this could result in some minor street flooding during heavy rain storms. Proposed pond A would treat storm water from Ingerson Road, Carlton . Drive, Fernwood Street and Fernwood Court, which currently drain into Lake Josephine via the ditch between Fernwood Court and Ingerson Court. If the City chose to not construct the proposed pond, the current drainage system could be repeated with grit chambers. Mayor Probst asked where the water from pond A would run. Mr. Brown stated that the water would run through the ditch system along Highway 51 to Lake Johanna. Mayor Probst noted that this water currently runs into Lake Josephine. He asked if changing this runoff pattern would alter the elevation of the lake. Mr. Brown stated that Lake Josephine receives most of its water from the south and southeast and he did not believe that the proposed pond would create any negative concerns regarding the elevation of the lake. Mr. Brown stated that two locations for ponds had been considered, one north of Ingerson Road and the other south ofIngerson Road. The pond to the north, proposed pond B, would treat storm water from Tiller Lane, Cannon Avenue and Dunlap Street which currently drain into the wetland located between Ingerson Road. This pond would be located in the existing wetlands. Mr. Brown stated that a munber of modifications for the drainage project could be made and he suggested that the neighborhood and Water Quality Task Force may wish to evaluate these options and make a recommendation. From a Capital Improvement point of view, Mr. Brown stated that the proposed plan would be the most expensive, however, it would do the best job of dealing with runoff water. . Mr. Brown stated that three options for the 2000 Street Improvement Project had been considered in the report. Package A included a full neighborhood reconstruction with no pond
