The ESI program in Loudoun County consists of a Minimum Submission Review (MSR) for all STPL, SBPL, CPAP and Geotechnical Report submissions, and all subsequent submissions, with the exception of Signature Set submissions. A first submission Team Peer Review meeting (TPR) is also held for all plan submissions. An acceptable transmittal from the MSR is required prior to any county submission. The program provides a plan completeness review to save time of the regulatory reviewers and speed the process of plan approval.
