Feasibility Report Page 8 2021 PMP Street and Utility Improvements City Project Number PW 21-0100 3.4 Water Main Existing water main along Edgewood Avenue and the west portion of Jerrold Avenue is proposed to remain in-place. These segments of water main do not have a history of water main breaks based on City records. Removal and replacement of water main along Edgewood and Jerrold would require removal of a significant portion of the existing curb, which is in good condition. Future replacement of the water main would be more cost effective in a future year when the roadway is due for full reconstruction. The redundant water main connection between Jerrold Avenue and Edgewater Avenue as shown on Appendix E should be considered for potential abandonment during the design process. The section of water main extends between closely spaced homes and would be difficult to repair or replace while protecting adjacent homes. Water main along the east portion of Jerrold Avenue and the full length of Glenpaul Avenue is recommended to be replaced with the improvements as shown in Appendix E. This work would include all gate valves, fittings, hydrants, water services and curb stops. 3.5 Drainage Reconstruction of the streets within the Hazelnut Park Neighborhood provides the opportunity to improve the drainage through installation of new or additional storm sewer facilities. Recommended storm sewer upgrades utilize the existing system to the extent possible, with drainage improvements consisting of new catch basin inlets and storm sewer along Glenpaul Avenue, Prior Avenue and Jerrold Avenue. Storm sewer drainage design will need to meet Rice Creek Watershed District (RCWD) requirements as outlined in Rule C. This section of the watershed regulations requires a permit for Public Linear Projects creating 10,000 square feet or more of impervious surface. Rule C requirements do not apply to mill, reclamation and overlay pavement projects. The project design will consider specific Best Management Practices (BMPs) such as bio- filtration and inline sediment/grit chambers placed before discharging into the downstream storm sewer system. Temporary erosion and sediment control devices will be utilized during construction in accordance with applicable NPDES permit and RCWD Rule D requirements. 3.6 Easements Street improvements as proposed within this report are anticipated to occur within the existing road right-of-way or easements. Public utility improvements are planned to occur within the right-of-way or currently dedicated drainage and utility easements. The need for permanent easement acquisition is not expected to construct the project as proposed. Temporary construction access of private property may be required to accommodate driveway repair, water and sewer service replacement, and final boulevard grading. Written permission or right of entry agreements will be secured from private property owners for these encroachments to the extent practical.
