County funds culvert replacements; DPW favors plastic pipes over steel in corrosive streams
Summary
Orange County approved $300,000 in bonding (matched with CHIPs funding) to replace three culverts; DPW staff said HDP plastic pipe is preferred over galvanized steel because acidic stream pH and salts erode coatings, and large culverts are inspected on a five-year cycle.
The Ways and Means Committee approved $300,000 in bonding to create a new capital project for various drainage improvements, with $200,000 coming from the State CHIPs program. Ryan McGuire said the project will replace three culverts—two on County Route 13 in the Town of Chester and one on County Route 84 in the Town of Warwick—and noted one site is frequently underwater.
Mr. McGuire explained the county typically avoids galvanized steel for smaller culverts because stream pH and salts erode protective coatings and prefers HDP (plastic) pipe for longevity. He added that the county inspects large culverts on a five-year cycle, doing about 80–100 inspections annually, equivalent to roughly 20% per year.
