West River Wall Improvement - Phase I (Corn Hill Segment)

19 RTR West river wall header

About the Project  

The West River Wall is located along the west side of the Genesee River adjacent to Exchange Boulevard, directly east of the Corn Hill Neighborhood within the Center City Downtown District. The site extends from Corn Hill Landing south to the Ford Street Bridge in the City of Rochester. The length of the wall to receive improvements is approximately 2,200 feet. This section of wall is characterized by a crumbing concrete flood control wall, overgrown vegetation, trail deficiencies and lack of public access to the River and its view sheds.

The City has obtained professional consulting engineering services to guide the planning and design of the reconstruction of the west wall of the Genesee River as well as the river corridor itself.  Critical safety inspections are needed to ensure that the wall can handle an emergency flood situation.  If the wall is found to be inadequate, necessary repairs/reconstruction will be designed.  Improvements to be considered include a new alignment for the Genesee River way Trail (a National Recreation Trail), waterfront pedestrian promenade, lighting, landscaping, fencing, and other pedestrian amenities. Opportunities for scenic overlooks, docks, and public art will be explored. 

This project has been identified as part of the ROC The Riverway initiative, a plan to revitalize the severely underutilized Genesee Riverfront in the core of Rochester, New York and to initiate greater interaction of the citizens and the waterfront. The proposed improvements to the West River Wall are working toward achieving this overall vision for Rochester and reestablishing our identity as a vibrant waterfront community. 

Project Description 

In collaboration with the New York State Canal Corporation (NYSCC), the New York State Department of State, the Corn Hill Neighborhood and the Plymouth Exchange Neighborhood (PLEX), the City of Rochester is leading a project on the west side of the Genesee River to rebuild the west river wall, enhance the area along the river and provide connections to the waterfront area for the adjacent community areas. The Corn Hill Segment 1 project site is located in Downtown Rochester along the west bank of the Genesee River occupying a 4+/- acre site that extends approximately 2,200 LF in the north south direction from Ford Street to the Corn Hill Landing Development and approximately 80 LF in the east-west direction from the Genesee River to Exchange St.

The existing river wall, constructed in 1918 as part of the Barge Canal System, has functioned to protect the surrounding area from flooding. The current wall is generally in poor condition and displays signs of significant deterioration. In 2008, in producing a seamless county-wide map for Monroe County, FEMA showed that the river wall was no longer providing flood protection due to the condition of the wall, resulting in newly mapped floodplain areas in Corn Hill.

The State of New York under the jurisdiction of the NYSCC currently owns the wall and immediate river frontage. Heavy vegetation and trees are present along the back side of the wall and it currently serves as a physical and visual barrier between the adjacent Corn Hill Neighborhood and the Genesee River. To the west of the river and wall, Exchange Boulevard further separates the neighborhood from the river and from the existing Genesee River way Trail, as there are limited safe locations for pedestrians to cross the street.

Utilizing a combination of construction funding from the City and NYSCC, the project will advance the City’s Local Waterfront Revitalization Program (LWRP) and builds upon preliminary planning and design funded by a previous EPF LWRP award.

A detailed hydrologic and hydraulic analysis of the Genesee River was conducted as part of the project in order to properly determine required flood protection elevations. Within the project limits, the river wall will be reconstructed in a manner aligned with NYSCC, USACE and FEMA accreditation standards to provide a contiguous line of flood protection along the project for the adjacent community while also improving visual and physical connection to the river and ultimately creating a new linear park. This will be accomplished through the construction of three distinct types of treatments along the project site.

  1. Plaza and North & South Tie-In Areas: At the riverward edge of new gathering plaza across from the Fitzhugh Place/Exchange Street intersection, and at the extreme north and south ends of the project (where the river wall passes under the Ford St. Bridge to the south and abuts the previously reconstructed wall at Corn Hill landing to the north), the existing river wall will be reconstructed/refaced from EL 517.3/516.8/518.7 (at the plaza and north and south tie-ins respectively) down to approximately 2 ft. below the normal pool elevation. Additionally, rock anchors will be installed through the wall to improve the wall’s stability. The plaza will feature aesthetic hardscaping, stairs, railings, planting beds and will provide overlook viewing of the river and Downtown skyline and gathering space opportunities during special events on the waterfront. Situated above the adjacent Exchange St. elevation, the plaza will feature stairs and ADA walkways down to the roadway configured in a manner to provide a “grand” entrance to the newly formed park.
  2. Berm/Lawn Areas: Over a length of approximately 400 ft. on either side of the new plaza, the existing river wall will be cut down and refaced from EL. 514.7 (approximately 2 ft. above the normal pool elevation) to approximately 2 ft. below the normal pool elevation. A trapezoidal earthen berm, setback approximately 40 feet behind the wall with a top elevation of EL 516.8/517.7 (north and south berm respectively), will be constructed to provide the required line of flood protection in these areas. Short runs of faced sheet pile retaining walls will tie each end of the berm areas into the full height river wall segments at the plaza and north/south tie-ins. The berms will slope gently towards the river along with a flat area immediately adjacent to the wall. This configuration will greatly improve visual sight lines of the river and provide for gathering/recreational lawn areas closer to the water. 
  3. Naturalized Shoreline Area: At the southern end of the project, over a reach of approximately 480 ft., the existing river wall will be cut down to EL 510.5 (approximately 2 ft. below the Genesee River’s normal pool elevation and the land behind the wall graded on a 1:3 to 1:5 slope tying up into existing ground thus allowing the river’s water edge to “enter” into the project site passing behind the plane of the existing wall. This sloped area will be treated with a combination of stepped cut stone blocks native to the area along with cobbles/rip-rap and planted with water-tolerant vegetation to create a natural shoreline effect and provide a unique opportunity to access the river’s edge along a stretch that is currently walled off on both side of the river within the Downtown corridor. All areas in the lawn and natural shoreline area that are riverward of the line of flood protection will be designed to resist storm flows. Throughout the length of the project, a 12-foot wide pedestrian/bicycle trail will be constructed, replacing the existing trail and providing better visual and physical access to the river and connections to the existing trail/promenade network at the north and south ends of the project.
