City of South Bend | Coal Line Trail (Phase II) from Riverside Drive to SR 933 (Des. No. 1401811) | Page 7LAWSON-FISHER ASSOCIATES LAWSON-FISHER ASSOCIATES P.C.P.C. As the trail heads east the alignment adjoins Angela Blvd. and Holy Cross College Athletic Fields. The proposed retaining wall reduces construction limits and more specifically eliminates impacts to the Softball Field Fence. Excavation limits for construction of the wall come within 5 feet of the fence. Therefore, construction staking for proper placement of the wall in advance of excavation will be important. Additionally, during construction, LFA will work with the Contractor to ensure excavation for the wall is protected to reduce potential for undermining the fence. AEP — 69kv Relocation AEP is completing the subsurface installation of a 69kv line adjacent to and crossing project limits of Phase 1 and Phase 2 of the Trail Project. The line has mostly been installed within the Trail Project Limits. In the approximate station range from 35+50 to 37+00, the trail profile is cutting approximately 3-feet below the existing ground. In this same area, the AEP line crosses the path. During line installation, the City worked with AEP and the Designer to coordinate the depth of power line to be approximately 42" below the finished grade of the trail profile. LFA will coordinate with the contractor and AEP during excavation to ensure there are no conflicts. Storm Sewer A proposed storm sewer system is included in the contract for a future drainage ditch north of the trail. The series of manholes and 24" storm pipe stretch from station 26+00, at the upstream end, to the discharge at an existing ditch at station 21+00. The upstream end shall be permanently marked to facilitate future locating activities. LFA will also coordinate with the contractor on the AEP power line to ensure the location does not conflict with the proposed storm line. PROJECT UNDERSTANDING Trail Nodes and Access Retention Wall Northshore Trail Crossing At the bridge's east end, a speed table and curb line adjustment will be installed as traffic calming measures to increase safety at the crossing. LFA will focus on proper grading and reinforcement of the speed table and pavement markings placement. Proper speed table approach grades and reinforcement are important to reduce longterm maintenance issues from winter snow plowing. Additionally, an adjacent 10' path and updated ADA Curb Ramp will be installed at the intersection of Angela Blvd., improving public trail access.Northshore Iroquois and Lafayette Trail Nodes Trail connections at these streets will include benches, bollards, decorative concrete and improve/create access from Angela Blvd. to the trail. The new connection across from Lafayette will require coordination with the Costello property to adjust fence locations and accomplish grading. Ensuring proper grading for ADA compliance and proper installation of features will be additional focus areas.Iroquois Lafayette Softball Field and Retaining Wall Location Riverside Trail Node This node serves to connect the Riverside Trail and Phase 1 of Coal Line Trail to this second phase. Here, LFA will focus on inspecting decorative concrete patterns, placement of foundations for the pre-cast pavilion, wayfinding sign foundations, water service connection for the drinking fountain, and bolt patterns/foundations for lighting, benches, trash receptacles and bollards. Pedestrian MOT is critical at this node as Riverside Drive and Angela Boulevard are busy corridors. Ensuring clear signage for safe pedestrian crossings will be paramount. Riverside Riverside Trail Node East Bank and SR 933 Trail Nodes The connection at these trail nodes constitutes the east project limits. At the East Bank Trail, LFA will ensure new pavement markings are properly laid out and executed. Additionally, the Rapid Flashing Beacon Sign shall be installed concurrently with removal of the existing crossing signage so a safe crossing is maintained. The final installation of bollards and Wayfinding signage will mark the entrance to the Coal Line Trail. East Bank Trail Node
