Chappaqua Downtown Revitalization – August 10, 2018

The recent storms have once again highlighted the need to upgrade our storm-sewer system (i.e. drainage). Over the past year we have replaced our entire water system and sewer system. Con Ed replaced their gas lines. All our work is staged pursuant to engineering. We are currently working on upgrading our stormwater system (i.e. drainage).

The existing stormwater sewer is currently being replaced with approximately 650 feet +/- of new twin 24” diameter reinforced concrete pipe and approximately 820 feet +/- of new 24” diameter ductile iron pipe. We are also replacing and/or repairing existing catch basins, frames and grates and installing 13 new reinforced concrete drainage structures in and along South and North Greeley Avenue as well. We started our drainage work at the existing concrete box culvert, located southerly of the existing Shell Service Station to Woodburn Avenue. Connections to the culvert continued up South Greeley Avenue. Once we hit the intersection of King Street and South Greeley Avenue – hopefully next week – we’ll attempt to install temporary connection on North Greeley Avenue to the culvert. Drainage work will then continue up North Greeley Avenue.

Some have asked why we couldn’t start the drainage work on North Greeley Avenue. The answer is that work needed to start at the culvert since it is standard construction practice to commence the drainage installation at the lowest point in order to allow for all upstream flows not be impacted during construction and will allow the contractor to maintain proper grade with all existing upstream conditions that may be encountered during construction. Storm drainage is expected to be completed by September.

Today, we have started our new curbs & sidewalks. They started saw cutting the roadway by Washington to Woodburn Ave for our new curbs. They will then excavate for our new granite curbs and start installation. This work is taking place during the day. Con Ed continue to move and replace their poles.
