Secondly, a new Candlewood Suites Hotel building will be constructed (along with associated parking areas and utilities) at the location of this removed building. Thirdly, the eastern building (Moon Hall) will be removed and a new Candlewood Suites Hotel building will be constructed (along with associated parking areas and utilities) at the location of this removed building. PHASE 1: SEQUENCE OF CONSTRUCTION FOR HARDY HALL DEMOLITION: INITIAL SEDIMENT AND EROSION CONTROL MEASURES: 1. INSTALL TEMPORARY GRAVEL CONSTRUCTION EXIT(S). REMOVE PAVEMENT AS NEEDED TO ACCOMMODATE CONSTRUCTION EXIT. 2. INSTALL TEMPORARY PERIMETER SEDIMENT BARRIERS (SILT FENCE, COMPOST SOCK, ETC.). 3. CONSTRUCT TEMPORARY SKIMMER SEDIMENT BASIN, INSTALL BAFFLES AND SKIMMER. COMPLETE ALL DEMOLITION OF STORMWATER STRUCTURES, STORMWATER PIPES, UTILITIES AND TREES AS NEEDED TO CONSTRUCT TEMPORARY SKIMMER SEDIMENT BASIN. 4. DEMOLITION AND REMOVAL OF EXISTING BUILDING, PAVEMENT, UTILITIES AND SIDEWALK AS NOTED ON THE DEMOLITION PLAN. 5. INSPECT AND MAINTAIN ALL SEDIMENT AND EROSION CONTROL MEASURES THROUGHOUT THE CONSTRUCTION PERIOD PER THE SWPPP REQUIREMENTS. CONSTRUCTION SEDIMENT AND EROSION CONTROL MEASURES: 1. AS DEMOLITION PROGRESSES, REMOVE SILT AND SEDIMENT BUILD-UP AT ALL TEMPORARY SEDIMENT BARRIERS, TEMPORARY INLET PROTECTION, AND TEMPORARY SKIMMER SEDIMENT BASIN. 2. COMPLETE BACKFILL AND TEMPORARY SOIL STABILIZATION OF DISTURBED AREAS AS REQUIRED. (TEMPORARY SEEDING AND MULCH) 3. AT THE COMPLETION OF DEMOLITION AND BACKFILL ACTIVITIES, AND PRIOR TO COMMENCING NEW BUILD CONSTRUCTION ACTIVITIES, REINSPECT AND REPAIR AS NEEDED ALL SEDIMENT AND EROSION CONTROL MEASURES.

GRADE AND PLACE MINERAL AGGREGATE BASE AT PAVEMENT AREAS. 8. CONSTRUCT CANDLEWOOD SUITES HOTEL. 9. PAVE PARKING AREAS AND FIRE LANES. 10. AS CONSTRUCTION PROGRESSES, REMOVE SILTAND SEDIMENT BUILD-UP AT ALL TEMPORARY SEDIMENT BARRIERS, TEMPORARY SKIMMER SEDIMENT BASIN AND TEMPORARY DIVERSION SWALES TO MAINTAIN ADEQUATE SEDIMENT CONTROL MEASURES. 11. THE TEMPORARY SKIMMER SEDIMENT BASIN (BAFFLES AND SKIMMER) MAY BE REMOVED WHEN THE CONTRIBUTING NON -STABILIZED DRAINAGE AREA IS LESS THAN ONE (1) ACRE. REMOVE EXISTING STORMWATER PIPE TO BACK OF NEW CURB. Page 2 Candlewood Suites Hotel Fort Bragg, NC S&ME Project No. 5147-19-014 12. BEGIN FINAL LANDSCAPING AND SITE STABILIZATION. SEE SHEET L-100-H FOR FINAL SITE STABILIZATION MEASURES. 13. CONSTRUCT STORMTECH CHAMBER SYSTEM BUT DO NOT DIRECT STORMWATER RUNOFF TO SYSTEM UNTIL FINAL SITE STABILIZATION. 14. ONCE FINAL STABILIZATION OF CONTRIBUTING DRAINAGE AREA TO THE STORMTECH CHAMBER SYSTEM HAS BEEN ACHIEVED AND APPROVED BYTHE D/B CONTRACTOR, INSTALL STORM DRAINAGE PIPES FROM D1 TO D1.1 AND C1 TO C0.1 AND DIRECT STORMWATER RUNOFF TO STORMTECH CHAMBER SYSTEM. 15. DEMOLISH THE EXISTING 24" RCP FROM STORM STRUCTURE D1 TO C0.1. 16. WHEN CONSTRUCTION IS COMPLETED, FINAL STABILIZATION OF THE ENTIRE SITE HAS BEEN ACHIEVED AND APPROVED BY THE D/B CONTRACTOR, REMOVE ALL TEMPORARY SEDIMENT AND EROSION CONTROL MEASURES AND STABILIZE ALL AREAS DISTURBED BY THESE TEMPORARY MEASURES. 16.
