TREE PROTECTION SHALL BE INSTALLED A MINIMUM OF 25' FROM THE TRUNK OF A TREE OR TO THE DRIP LINE, WHICHEVER IS GREATER. 22. THE STREAM BUFFER MITIGATION PLAN IS TO ENHANCE THE EXISTING BUFFER BY CAREFULLY SELECTING AND 1� REMOVING DAMAGED, UNHEALTHY, AND INVASIVE PLANT AND TREE SPECIES AND REPLACING THEM WITH (55) -1-12" CALIPER CANOPY TREES OR 6' EVERGREEN TREES, (55) - %" CALIPER UNDERSTORY TREES OR 4' EVERGREEN TREES, AND (55) -15" SHRUBS. CANOPY TREES SHALL BE RIVER BIRCH OR RED MAPLE. UNDERSTORY TREES SHALL BE REDBUD OR DOGW00. EVERGREEN TREES SHALL BE EASTERN RED CEDAR. SHRUBS SHALL BE WAX MIYRTLE OR ITEA VIRGINICA MAINTENANCE: IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL. THE FOLLOWING ITEMS WILL BE CHECKED IN PARTICULAR: 1. THE INLET PROTECTION WILL BE CHECKED EACH MORNING FOR SEDIMENT AND DEBRIS. ALL LOCATIONS ARE TO BE KEPT TIGHT, CLEAN AND FULLY OPERATIONAL. 2. EACH EVENING THE PAVED SURFACE BEYOND THE CONSTRUCTION ENTRANCE SHALL BE WASHED DOWN OR SWEPT CLEAN. 3. THE CONSTRUCTION ENTRANCE WILL BE CHECKED REGULARLY. IF THE STONE BECOMES CLOGGED BY MUD OR SEDIMENT IT SHALL BE REMOVED AND CLEANED OR REPLACED. 4. THE TEMPORARY DIVERSION DIKES AND SEDIMENT TRAP WILL BE CHECKED REGULARLY FOR DETERIORATION AND SEDIMENT DEPOSITION AND MAINTAINED IF NECESSARY. 5. SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS ESTABLISHED. AREAS SHALL BE RETREATED IF SO DETERMINED BY EROSION INSPECTOR IN ACCORDANCE WITH THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK.
