June 10, 2021: Coastal flood risk and potential mitigation methods are the focus of a report prepared and presented by CBCL Limited in 2019 for Region of Queens Municipality.
“Liverpool’s Coastal Flooding Mitigation Study was a thorough study of the risks and challenges present in Liverpool’s waterfront with regard to flooding, and includes historical data, as well as projections of changing tide levels and extreme weather. Each of the four options in the flood mitigation report come with very large price tags without any guarantee of success. Market Street, which turns into Bristol Avenue on the south side of Liverpool’s bridge, is the main artery in and out of Liverpool, and a crucial area to look at flood mitigation efforts, in the interest of public safety,” said Darlene Norman, Mayor of Region of Queens Municipality.
The waterfront parking lot in Liverpool and the low lying Market Street and Water Street roadways are areas that have flooded for many years in times of extreme high tides and with storm surge, and is occurring with increasing frequency at higher elevations, adversely affecting some local businesses, the parking lot, and access to other areas of Liverpool. CBCL Limited presented the report at a public Council meeting on November 12, 2019. After further review and discussions with CBCL Limited, Council at that time felt that none of the four options were in the best interests of the Municipality and its downtown business core, with estimated costs ranging from $2,825,000 to $9,100,000 plus the costs of purchasing and demolishing several buildings.
At the June 8, 2021 regular Council meeting, a motion was approved to apply for Flood Risk Infrastructure Investment Program (FRIIP) funding to raise the roadway between the Liverpool bridge and Water Street along Market Street to an elevation closer to the bridge riding surface. This project, if completed, will require some design changes in the area to ensure the adjacent properties are able to maintain access as well as a new configuration with the sidewalk being below the street grade. This concept is seen in larger urban areas such as Halifax. While this project will benefit motor vehicles using the roadway, there is not a flood protection benefit directly to existing commercial structures in that area. If the FRIIP funding is approved for this $500,000 project, construction would begin in the 2022-2023 fiscal year.
