Seedbed Preparation:
1 Chisel compacted areas and spread topsoil three inches deep over adverse soil conditions, if
available
2 Rip the entire area to six inches deep
3 Remove all loose rock, roots and other obstructions, leaving surface reasonably smooth and uniform.
4. Apply agricultural lime- fertilizer and superphosphate uniformly and mix with soil (see mixture below).
5. Continue tillage until a well -pulverized: firm, reasonably uniform seedbed is prepared four to six inches
deep.
6. Seed on a freshly prepared seedbed and cover seed lightly with seeding equipment or cultipack after
seeding
7 Mulch immediately after seeding and anchor mulch
8 Inspect all seeded areas and make necessary repairs or reseedmgs withn the planting season, if
possible. If stand should be more than 60% damaged: re-establish following the original lime, fertilizer
and seeding rates
9. Consult S&EC Environmental Engineers on maintenance treatment and fertilization after permanent
cover is established.

EROSION CONTROL NOTES:
1. ALL INDIVIDUAL LOT EROSION CONTROL MEASURES SHALL BE INSTALLED
IN ACCORDANCE WITH DURHAM COUNTY REQUIREMENTS.
2. THE TYPICAL INDIVIDUAL LOT EROSION CONTROL DETAILS CONTAINED ON
THIS PLAN ARE PROVIDED FOR PURPOSES OF ILLUSTRATING VARIOUS
TYPICAL CONDITIONS, AND SHALL BE ADAPTED AND MODIFIED AS
NECESSARY IN ORDER TO ADDRESS THE SPECIFIC CONDITIONS FOR EACH
LOT. THE TYPICAL DETAILS MAY NOT ADDRESS EACH UNIQUE SITUATION,
AND SHOULD BE USED AS A GENERAL GUIDELINE FOR THE TYPES OF
CONTROL MEASURES PROVIDED. SOME LOTS MAY REQUIRE COMBINING
ELEMENTS OF MORE THAN ONE TYPICAL DETAIL IN ORDER TO PROVIDE
ADEQUATE EROSION CONTROL MEASURES.
3. SILT FENCE SHALL BE INSTALLED ALONG THE LOW SIDE(S) OF THE LOT
SUCN THAT ALL RUNOFF FROM DISTURBED AREAS WILL BE PROTECTED
BY SILT FENCE PRIOR TO CROSSING ANY LOT LINE.
4. SILT FENCE OUTLETS SHALL BE INSTALLED AT ANY LOCATION WHERE
RUNOFF LEAVES THE PROPERTY IN A CONCENTRATED FLOW CONDITION
SUCH AS SWALES, DITCHES OR ANY OTHER SIMILAR TOPOGRAPHIC
DRAINAGE FEATURE.
5. A GRAVEL PAD AT LEAST 20' WIDE AND 50' LONG MUST BE INSTALLED
AT THE ACCESS POINT INTO THE LOT.
6. ALL AREAS WITHIN 25' OF THE EDGE OF PAVEMENT OF THE STREET
MUST BE STABILIZED BEFORE ISSUANCE OF A CERTIFICATE OF
OCCUPANCY. THE EXISTING STREET SHOULDER AND/OR DITCH ALONG
THE LOT FRONTAGE SHALL BE KEPT FREE OF SEDIMENT AND MAINTAINED
IN A MANNER SUCH THAT THE DRAINAGE AND STABILIZATION ASPECTS
OF THE PUBLIC RIGHT-OF-WAY ARE NOT ADVERSELY AFFECTED BY THE
CONSTRUCTION ACTIVITY ASSOCIATED WITH THE LOT DEVELOPMENT.
7. ALL DISTURBED AREAS THAT ARE SUBJECT TO EROSION AND MOVEMENT
OF SEDIMENT OFFSITE FROM THE LOT MUST BE PROVIDED WITH GROUND
COVER OR OTHER PROTECTIVE MEASURES SUFFICIENT TO RESTRAIN
EROSION AND CONTROL OFF -SITE SEDIMENTATION.
8. THE DURHAM COUNTY EROSION CONTROL INSPECTOR MAY REQUIRE
ADDITIONAL EROSION CONTROL MEASURES OR MODIFICATIONS TO THE
EROSION CONTROL PLAN BASED ON FIELD CONDITIONS.
