PROJECT PURPOSE

This project will reduce property and street flooding. Per the 2005 Stormwater Master Plan, the Rayola Park or also known as the YMCA Regional Detention and offsite channel improvements was identified as a project due to inadequate culvert size, channel capacity and detention resulting in property and street flooding. As a result, this project includes vertical concrete wall, replacement of the culvert with a 2-cell 8?x4? reinforced concrete box and 10?x4? reinforced concrete box. In addition, stormwater detention improvements within the existing ball fields offset any potential increase in flow rates because of the work and the work mentioned upstream. Estimated cost of this project is $4,200,000.00.
