Feasibility Report Page 13 Snelling Avenue North and County Road E - Street and Utility Improvements City Project Number PW 20-0100 DRAFT project from the Area 1 roadway improvements south of County Road E. The Council further directed staff to work with Ramsey County to conduct additional traffic study of the intersection after traffic patterns return to more stable condition in 2021 or 2022. 3.3 Street Improvements: Cummings Lane and Bussard Court As mentioned in Section 2, Cummings Lane and the east 100-feet of Bussard Court are highly deteriorated and can no longer be cost-effectively maintained. Proposed improvements for Cummings Lane consist of reclaiming the existing pavement, shaping the generated aggregate material to raise the center crown to improve pavement drainage and repaving the roadway with 4-inches of bituminous pavement. The installation of curb and gutter is not proposed along Cummings Lane. Improvements also include replacement of the storm sewer structure at the low point of the road and the culvert extending into the drainage ditch along Trunk Highway 51. Proposed street improvements for the 100-foot section of Bussard Court include removal of the pavement, reconstruction of the upper two feet of subgrade with granular and aggregate base, replacement of damaged curb and placement of 4-inches of new bituminous pavement. 3.4 Utility Improvements: Area 1 – Snelling Ave N south of County Road E Sanitary Sewer Sanitary sewer along Snelling Avenue is located approximately 30 feet or more to the east and west of the roadway pavement. The segment between Arden Place and Skiles Lane was previously improved with a CIPP liner. Based on the recent condition evaluation summarized in Section 2, the recommended sanitary sewer improvements are limited to replacement of the 8-inch diameter crossing at Skiles Lane east as shown in Appendix D. This segment of sewer was originally constructed with a combination of VCP and CIP pipe materials, which is believed to have been done as an alternative to installing a steel casing pipe within the former State highway. The CIP section of pipe is in a highly deteriorated condition. Water Main Under the Alternative 1 scenario (trail), water main along Snelling Avenue North would be replaced with new ductile iron or PVC pipe due to the significant excavation and disturbance required for construction of the trail and associated storm sewer system. Under the Alternative 2 scenario (no trail), a majority of existing water main south of County Road E 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 between Lemetti Lane and Bussard Court is recommended to improve reliability of the water supply feed from Cummings Lane, particularly for Bussard Court, which is supplied from only one direction. A water main break between Bussard and Cummings Lane would disrupt water service to 19 or more homes. The locations of water main improvements are indicated in Appendix D.
