I I I I I I I I I I I I I I I I I I I section, shown on Exhibit 7, consists of a 32-foot wide street with concrete curb and gutter. This typical section will require widening or narrowing of the existing roadways within the project area. Upland Avenue and Tipton Avenue will be reconstructed as an exception to the adopted typical section. Currently Upland Avenue and Tipton Avenue have no curb and gutter, which allows cars to park partially on the grass. With the construction of barrier curb, it is proposed that a 28-foot wide street be constructed so residents can safely park and travel on the street. The proposed pavement section for all the streets consists of 7 inches Class 5 aggregate base, 2 inches of bituminous base course, and 1.5 inches of bituminous wear course. The proposed street section has been verified by a geotechnical investigation. The proposed street sections are shown as Exhibit 7. In accordance with City Council direction to construction pedestrian trails with new construction, the proposed improvements also include a 6-foot wide sidewalk located on both sides on the majority of Fifth Street and along the west side of Upland Avenue. Existing sidewalk will be removed and reconstructed to City Standards. Areas where sidewalk will not be constructed include streets where sidewalk construction is not feasible due to extreme grades or where it is desired to protect trees. Other locations where sidewalk may not be feasible will be determined during design. Sidewalk along the west side of Upland Avenue is proposed as the best option to connect the trail system north of TH 10 and Main St. The proposed improvements also include the closure of three accesses to TH 10, Seymour Avenue, Rush Avenue, and Quinn Avenue. MN/DOT will be closing these accesses during their next highway improvement of TH 10, so it is proposed that they be closed under the City's direct in the 2005 Street Reconstruction Project. Seymour Avenue has a platted right-of-way but is currently a dirt road that is seldom used. It is proposed that this be closed completely from Fifth Street to TH 10. Rush Avenue and Quinn Avenue have currently right turn only access to TH 10. It is proposed that these accesses be closed at TH 10 and turn-a-rounds constructed at the TH 10 right-of-way. As with the 2003 project, it is proposed to have Elk River Municipal Utilities install street lights after the project is complete. Storm Sewer A review of the drainage patterns and pavement conditions reveals that some locations do not currently drain runoff away effectively and has contributed to the deterioration of the pavement. Replacement and addition of curb and gutter, slight grade revisions, and storm sewer extensions are needed to facilitate drainage. A significant area north of TH 10 crosses from north to south through a highway culvert located east of Upland Avenue. This drainage area is tributary to the storm sewer system in the rear yards between Tipton Avenue and the West end of 5th Avenue. City staff has had preliminary discussions with the property owner north of TH 1 0 regarding the proposed drainage improvements to this drainage system, which include repair of existing rear yard storm sewer pipe, adding storm sewer pipe capacity along Tipton Avenue and Upland Avenue, and potential ponding to control discharge rate and water 4
