The properties along the south side of Main Street from Tipton Avenue to Lowell Avenue currently discharge wastewater to a separate sewer pipe located within an easement between the Mississippi River and Main Street. For 2010 the City budgeted for a study to determine what modifications will be necessary for this section of pipe with improvements likely to follow soon after. If the study determines that abandonment is the most practical option, the affected properties will require service from Main Street. As a part of the project completed in 1988, 4" service laterals were extended from the sewer main in Main Street south to the right-of-way line at each of the properties. Once the southerly sewer line is abandoned, the adjacent properties will be able to connect to the existing service laterals without disturbing Main Street. Watermain Existing watermain is located throughout the project area. A 16-inch pipe extends from Orono Road to Tipton Avenue and a 6-inch from Tipton Avenue to Lowell Avenue. The condition of the existing system was discussed with Mr. David Berg, Superintendent of Water and Electric Technologies with Elk River Municipal Utilities (ERMU) on April 16, 2010. To the best of Mr. Berg's knowledge there are no major deficiencies to the existing water distribution system. The existing watermain is shown on Exhibit 3. Storm Sewer Main Street conveys stormwater through a storm sewer system varying in size from 12- inches to 18-inches in size. Within the project area there are five main discharge points from Main Street. The first is between Orono Road and Watson Avenue where stormwater discharges to Lake Orono. Three of the discharge points are between Watson Avenue and Norfolk Avenue which discharge into Elk River. The final two locations are at Morton Avenue and Lowell Avenue which ultimately discharge into the Mississippi River. The existing storm sewer is shown as Exhibit 4. In discussions with Mr. Phil Hals, Street Superintendant from the City of Elk River, on April 16, 2010, the existing storm sewer system will not be televised. To the best of Mr. Hals' knowledge, there are no known deficiencies with the existing storm system. Existing Private Utilities Private utilities that have facilities in or near the project area will be notified of the project and requested to incorporate repairs and replacements with the project as needed at their own cost. Private utilities include Elk River Municipal Utilities, Qwest, Centerpoint Energy, Charter Communications, Northstar Access, First National Financial Services, Qwest, and Sherburne Telephone Systems. V. PROPOSED IMPROVEMENTS The proposed improvements for the Main Street Pavement Rehabilitation Project includes pavement reclamation and replacement, replacement of selected pedestrian curb ramps, and repair of small quantities of sidewalk and concrete curb. It is not anticipated that any work to the sanitary sewer, watermain, or storm sewer systems will be completed at this time. The street sections include all of Main Street east from Orono 3
