Performance/ Erosion and Sediment Control Bonding

Prior to approval of a record plat or site plan, the developer or property owner must provide a financial guarantee in the form of a corporate surety bond, a letter of credit from a bank, or cash to assure the timely construction and completion of improvements in accordance with the approved plans.

For erosion and sediment control (E&S) permits, the bond, letter of credit, or cash guarantees that the site can be stabilized if the work is not completed. Performance and proffer bonds guarantee that work shown on approved development plans can be completed. E&S bonding procedures are governed by Section 1220 of the Loudoun County Codified Ordinances. Performance and Proffer bonding is governed by Section 8.300 of the Loudoun County Facilities Standards Manual.
