GENERAL NOTES:
1. HAVENER PARCEL: DB 6385/PG 195, PIN 9970-13-2218, 29.12 ACRES, ZONING: AR
2. PARCEL IS LOCATED WITHIN THE LITTLE RIVER PROTECTED WATERSHED OVERLAY DISTRICT.
3. ALL EXISTING CONDITIONS AND TOPOGRAPHIC INFORMATION TAKEN FROM ORANGE COUNTY GIS AND
AERIAL PHOTOGRAPHS. ACTUAL FIELD LOCATIONS AND ELEVATIONS MAY VARY FROM THOSE SHOWN
AND ANY PROPOSED LOCATIONS AND ELEVATIONS MAY NEED TO BE FIELD ADJUSTED TO
ACCOMMODATE THE EXISTING DATA.
4. THIS PLAN IS FOR EROSION AND SEDIMENT CONTROL DESIGN ELEMENTS ONLY. REFER TO THE PLANS
TITLED "HAVENER RESIDENCE" FOR ALL GRADING AND UTILITIES.

SOIL AMENDMENTS
FOLLOW RECOMMENDATIONS OF SOIL TESTS OR APPLY 2,000 LB/ACRE GROUND AGRICULTURAL
LIMESTONE AND 750 LBS/ACRE 10-10-10 FERTILIZER
MULCH
APPLY 4,000 LB/ACRE STRAW. ANCHOR STRAW BY TACKING WITH ASPHALT, NETTING OR A MULCH
ANCHORING TOOL. A DISK WITH BLADES SET NEARLY STRAIGHT CAN BE USED AS A MULCH
ANCHORING TOOL.
MAINTENANCE
REFERTILIZE IF GROWTH IS NOT FULLY ADEQUATE. RESEED, FERTILIZE AND MULCH IMMEDIATELY

SEEDING NOTES
1. AFTER AUGUST 15 USE UNSCARIFIED SERICEA SEED.
2. WHERE PERIODIC MOWING IS PLANNED OR A NEAR APPEARANCE IS DESIRED, OMIT SERICEA AND
INCREASE KOBE LESPEZEDA TO 40 LB/ACRE.
3. TO EXTEND SPRING SEEDING DATES INTO JUNE, ADD 15LB/ACRE HULLED BERMUDAGRASS.
HOWEVER, AFTER MID-APRIL IT IS PREFERABLE TO SEED TEMPORARY COVER.
NURSE PLANTS
BETWEEN MAY 1 AND AUGUST 15, ADD 10 LB/ACRE GERMAN MILLET OR 15LB/ACRE SUDANGRASS.
PRIOR TO MAY 1 OR AFTER AUGUST 15 ADD 40 LB/ACRE RYE (GRAIN).
SEEDING DATES
BEST POSSIBLE
FALL: AUGUST 25 - SEPTEMBER 15 AUGUST 20 - OCTOBER 25
LATE WINTER: FUBRUARY 15 - MARCH 21 FEBRUARY 1 - APRIL 15
FALL IS BEST FOR ALL FESCUE AND LATE WINTER FOR LESPEDEZAS. OVER SEEDING OF KOBE
LESPEZEDA OVER FALL -SEEDED TALL FESCUE IS VERY EFFECTIVE.
SOIL AMENDMENTS
APPLY LIME AND FERTILIZER ACCORDING TO SOIL TESTS, OR APPLY 4,000 LB/ACRE GROUND
AGRICULTURAL LIMESTONE AND 1,000 LB/ACRE 10-10-10 FERTILIZER.
MULCH
APPLY 4,000 LB/ACRE GRAIN STRAW OR EQUIVALENT COVER OF ANOTHER SUITABLE MULCH. ANCHOR
STRAW BY TACKING WITH ASPHALT, NETTING OR ROVING OR BY CRIMPING WITH A MULCH ANCHORING
TOOL. A DISK WITH BLADES SET NEARLY STRAIGHT CAN BE USED AS A MULCH ANCHORING TOOL.
MAINTENANCE
REFERTILIZE IN THE SECOND YEAR UNLESS GROWTH IS FULLY ADEQUATE. MAY BE MOWED ONCE OR
TWICE A YEAR, BUT MOWING IS NOT NECESSARY. RESEED, FERTILIZE AND MULCH DAMAGED AREAS
IMMEDIATELY.

MAINTENANCE:
• NEW SEEDLINGS SHOULD BE INSPECTED FREQUENTLY AND MAINTENANCE PERFORMED AS NEEDED. IF RILLS ANG
GULLIES DEVELOP, THEY MUST BE FILLED, RE -SEEDED, AND MULCHED AS SOON AS POSSIBLE. DIVERSIONS MAY BE
NEEDED UNTIL NEW PLANTS TAKE HOLD.
• DAMAGE TO VEGETATION FROM DISEASE, INSECTS, TRAFFIC, ETC., CAN OCCUR AT ANY TIME.HERBICIDES AND REGULAR
MOWING MAY BE NEEDED TO CONTROL WEEDS. DUST AND SPRAYS MAY BE NEEDED TO CONTROL INSECTS.
• WEEK OR DAMAGED SPOTS MUST BE RELIMED, FERTILIZED, MULCHED, AND RESEEDED AS PROMPTLY AS POSSIBLE.
