DESC bonding for final grade

When final grade cannot be achieved due to weather, the permittee may submit the completed form on page 2 of the Town bonding policies to request approval to post a Fiscal Surety. Bonds will be approved only in cases where final grade cannot be established because of adverse site conditions caused by weather at the time of the final inspection. Bonds for reasons other than weather-related site conditions will be considered on a case-by-case basis and are subject to denial. Temporary sediment controls are required at all times regardless of weather conditions.
