Construction Sequence Schedule: Spring (ProJected seaeon to start): Locate areas of tree protection. instali grovel construction entronce, instdi temporary sOt fence, strtp and stodcpile topsoil. Excavate building areas and other earthwork (lakes, roads, swoles, sewers, etc.) Spring/Summer: Install strawbale tnlet protection. Install rodc chute outlet protection. Instdl t�nporary erosion control blankets as needed. Trodc in ridges with dozer deota on all slopea greater than six percent and around side siopes of lakes. Summer/Fdl: Apply sod in all areas that aro flnish grndsd. Appiy t�nporary aeeding in areas where earthwork construction is halted and aree will be bare and exposed for more than two months. Matntain erosfon control proctices as p� eroaton contrd maintenance achedule above. R�r►ove temporary erosion controi measures in stabilized areas that have been sodded. Wtnt�/Spriny: Appiy dotmant aeeding on any areas that ahow a need fa i� Continue maintenance of existing eroaton contrd proctices. Spring/Summer/Fall {following yeor): Stabilize all open ground and remove temporary ero5ion control practices. implament final Icndscape plan. �ORMS\18545ECM EROSION CONTROL FOR INDIVIDUAL LOTS 1. CONSTRUCT A GRAVEL DRIVE 2. CONFINE ALL TRAVEL TO THE GRAVEL DRIVE 3. PRESERVE AS MUCH OF THE EXISTING VEGETATION AS POSSIBLE 4. IF THERE ARE LARGE EXPOSED AREAS ON OR NEAR SLOPES A SILT FENCE MAY BE REQUIRED 5. AFTER FINAL GRADING, SEED OR SOD THE YARD AS SOON AS POSSIBLE 6. AFTER A YARD IS RE-VEGETATED, REMOVE ALL TEMPORARY EROSION CONTROL MEASURES ALL AREAS NOT DENOTING PERMANENT SEEDING OR FIB�R BLANKETS SHALL BE TEMPORARILY SEEDED.
