The proposed improvements also include a 6-foot wide sidewalk located on both sides of the majority of the streets within the project area. 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. For example, on Norfolk Avenue it will not be feasible to construct a sidewalk on the west side of the street because of the grade difference between the roadway and adjacent Hanke Pit at the intersection of Norfolk Avenue and Main Street. Other locations where sidewalk may not be feasible will be determined during design. It is proposed that Elk River Municipal Utilities will install street lighting after the project. Storm Sewer A review of the drainage patterns and pavement conditions reveals that some locations do not currently drain runoff away effectively. Replacement and addition of curb and gutter, slight grade revisions, and storm sewer extensions are needed to facilitate drainage. The existing storm sewer system will be extended and inlets installed at appropriate locations to provide adequate drainage for the area. Storm sewer is shown as Exhibit 5. Sanitary Sewer The sanitary sewer within the project area was televised to determine the extent that repairs or replacement would be necessary. A review of the Closed Circuit Televised Sewer Inspection Report determined that although regular maintenance would be required to remove roots in certain areas no structural damage had occurred to the pipe. The report was discussed with Mr. Gary Leirmoe, Chief Operator, and it was determined that no improvements or repairs to the sanitary sewer system are necessary. Watermain Watermain improvements were discussed with Mr. Bryan Adams, General Manager of Elk River Municipal Utilities (ERMU). The following items were a result of the discussions and will be incorporated during design: Some existing services may be lead or other non-copper material. ERMU policy states that non-copper services must be replaced with copper. These services will be identified and replaced as part of the improvements project. The existing 4-inch watermain on Fourth Street should be replaced with a larger size main. The exact size will be determined during design through modeling. It is anticipated that a 12-inch main will be required. The existing 4-inch watermain should be replaced with 8-inch watermain throughout the remainder of the study area. · Where no watermain exists on Quinn Avenue, Oxford Avenue, and Norfolk Avenue, install 8-inch watermain. 4
