About this file
This is an Erosion and Sediment Control Plan prepared by The Lane Group Inc. for Washington County, Virginia's new Emergency Medical Services (EMS) facility located in Glade Spring at the Highlands Business Park. The plan, dated January 30, 2026, outlines comprehensive erosion control measures for a construction project involving approximately 2.85 acres of land disturbance. The document establishes specific requirements for vegetative and structural erosion control practices, including temporary construction entrances, silt fencing, storm drain inlet protection, rock check dams, temporary and permanent seeding, mulching, and soil stabilization blankets and matting. All erosion and sediment control measures must comply with minimum standards and specifications outlined in the Virginia Stormwater Management Handbook. The plan requires contractor notification to the plan approving authority one week prior to the preconstruction conference, commencement of land-disturbing activities, and final inspection. A copy of the approved plan must be maintained on-site at all times.
The contractor is responsible for inspecting all erosion control measures at minimum every seven calendar days and after any rainfall event producing 0.5 inches or greater precipitation, with necessary repairs completed immediately. Perimeter slopes and all slopes steeper than 3:1 must achieve stabilization within 7 calendar days of the last land-disturbing activity, while all other disturbed areas require stabilization within 14 calendar days. All disturbed, unpaved, and ungraveled areas must be seeded and mulched, with slopes exceeding 2% requiring erosion control matting anchoring. Following project completion, all temporary erosion control measures must be removed, and permanent vegetative cover must be established on all denuded areas not otherwise permanently stabilized. The plan references the Virginia Erosion & Sediment Control Handbook for detailed installation requirements for any measures not specifically detailed on the plan sheet.

DISTURBANCE.
4. A COPY OF THE APPROVED EROSION AND SEDIMENT CONTROL PLAN SHALL BE MAINTAINED ON THE SITE AT ALL TIMES.
5. PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES IN AREAS OTHER THAN INDICATED ON THESE PLANS (INCLUDING, BUT NOT LIMITED TO, OFF-SITE BORROW OR WASTE AREAS), THE CONTRACTOR SHALL SUBMIT A SUPPLEMENTARY EROSION AND SEDIMENT CONTROL PLAN AS DETERMINED BY THE PLAN APPROVING AUTHORITY.
6. THE CONTRACTOR IS RESPONSIBLE FOR INSTALLATION OF ANY ADDITIONAL EROSION CONTROL MEASURES NECESSARY TO PREVENT EROSION AND SEDIMENTATION AS DETERMINED BY THE PLAN APPROVING AUTHORITY.
7. THE ENGINEER, INSPECTOR, LOCAL BUILDING OFFICIAL, OR VDCR RESERVE THE RIGHT TO REQUIRE EROSION CONTROL MEASURES IN ADDITION TO THOSE SHOWN IF CONDITIONS WARRANT IN ORDER TO ADDRESS EROSION.
8. ALL DISTURBED AREAS ARE TO DRAIN TO APPROVED SEDIMENT CONTROL MEASURES AT ALL TIMES DURING LAND DISTURBING ACTIVITIES AND DURING SITE DEVELOPMENT UNTIL FINAL STABILIZATION IS ACHIEVED.
9. THE TOTAL AREA OF DISTURBANCE IS ESTIMATED TO BE 2.85 ACRE.
10. THE CONTRACTOR SHALL INSPECT ALL EROSION CONTROL MEASURES NO LESS THAN EVERY 7 CALENDAR DAYS AND AFTER EACH RUNOFF-PRODUCING RAINFALL EVENT PRODUCING 1/2 INCH OF PRECIPITATION OR GREATER. ANY NECESSARY REPAIRS OR CLEANUP TO MAINTAIN THE EFFECTIVENESS OF THE EROSION CONTROL DEVICES SHALL BE
