NARRATIVE
THE INTENT OF THIS PLAN IS TO ALLOW RYAN HOMES TO DEVELOP LOTS
INDIVIDUALLY AND INDEPENDENTLY OF OTHER LOTS DESIGNATED FOR
HOME CONSTRUCTION. LOT CONSTRUCTION FOR ADJACENT LOTS MAY
BEGIN AND END AT DIFFERENT TIMES. THEREFORE, EACH LOT SHOULD
HAVE PERIMETER CONTROLS AND A CONSTRUCTION ENTRANCE. REFER TO
DETAIL SHEETS FOR DETAILS OF INDIVIDUAL LOT EROSION CONTROL
MEASURES.
GENERAL NOTES
1. PROPERTY, RIGHT-OF-WAY, EASEMENT, ETC. LINEWORK WAS TAKEN
FROM AN AUTOCAD FILE PROVIDED BY STEWART, ON MARCH 13,
2021.
2. THESE PLANS ARE ONLY FOR EROSION CONTROL FOR THE
DEVELOPMENT OF LOTS 15-19 & 370-377. REFER TO APPROVED

"RIPARIAN AREA".
S. ALL SOIL EROSION AND SEDIMENT CONTROL PLANS AND MEASURES
MUST CONFORM TO THE MINIMUM APPLICABLE STANDARDS
SPECIFIED IN NORTH CAROLINA'S EROSION AND SEDIMENT CONTROL
PLANS.
6. ALL DISTURBANCE WITHIN THE 25' TREE AND VEGETATION
PROTECTION ZONE SHALL COMPLY WITH SECTION 16 OF THE WAKE
COUNTY UDO. ANY PROTECTED TREES THAT ARE REMOVED SHALL BE
REPLACED PER WAKE COUNTY LIDO 16-12-7.

S. PROTECT ANY EXISTING STORM INLETS INLETS WITH BLOCK AND GRAVEL
INLET CONTROLS OR OTHER APPROVED MEASURES. BEGIN
CONSTRUCTION, BUILDING ETC.
6. STABILIZE SITE AS AREAS ARE BROUGHT UP TO FINISH GRADE WITH
VEGETATION, PAVING, DITCH LININGS ETC. SEED AND MULCH DENUDED
AREAS PER GROUND STABILIZATON TIME FRAMES.
7. WHEN CONSTRUCTION IS COMPLETE AND ALL AREAS ARE STABILIZED
COMPLETELY, CALL BETSY PEARCE AT 919-868-6414 FOR AN INSPECTION
BY THE WATERSHED MANAGER.
8. IF THE SITE IS APPROVED, REMOVE SILT FENCE, SILT FENCE OUTLETS,
ETC., AND SEED OUT OR STABILIZE AND RESULTING BARE AREAS.
9. WHEN VEGETATION HAS BECOME ESTABLISHED, CALL FOR A FINAL SITE
INSPECTION BY THE WATERSHED MANAGER, BETSY PEARCE AT
919-868-6414. OBTAIN A CERTIFICATE OF COMPLETION.
CONSTRUCTION SEQUENCE NOTES
1. THE CONTRACTOR IS RESPONSIBLE FOR ENSURING THAT EROSION IS
MINIMIZED AND THAT COMPLIANCE WITH ALL APPLICABLE FEDERAL,
STATE, AND LOCAL LAWS, REGULATIONS, AND ORDINANCES IS
MAINTAINED THROUGHOUT EXECUTION OF THIS PROJECT.
2. THE CONTRACTOR SHALL INSPECT AND REPAIR ALL EROSION DEVICES AT
LEAST ONCE EVERY 7 CALENDAR DAYS AND WITHIN 24 HOURS OF EVERY
0.5 INCH OR GREATER RAINFALL EVENT.
3. THE CONTRACTOR SHALL ENSURE THAT THE EROSION CONTROL DEVICES
REMAIN UNDISTURBED UNTIL THE CONTRIBUTING UPSTREAM AREAS
HAVE BEEN STABILIZED AND APPROVED.

1.If required by Wake County, tree protection fence shall be
installed along the rear property line when adjacent to riparian
buffer zones, wetlands and/or 25 ft. Tree and Vegetation
Protection Zone. If the lot is subject to a municipal planning
jurisdiction, then the builder is responsible for verifying the
applicable tree protection standards and for installation of tree
protection measures as required by the municipality.
2.Install silt fence on low elevation sides of each lot and install silt
fence outlets shown on schematic/diagram and as needed.
3.Install required silt fence within 10 feet of property lines to
ensure there is no conflict with septic system. It is the
responsibility of the builder to ensure septic system is not
impacted by silt fence installation.
4.It is the responsibility of the builder to ensure installation of
erosion control measures does not impact septic system and
repair areas.

7.If the disturbed area is greater than one acre, a custom erosion
control plan should be submitted for the 15-day review cycle. The
plan should address berms/diversions and sediment traps and
basins.
8.If multiple lots share silt fence with none installed between the
lots, a revised plan will be required.
9.Inlets downstream of disturbances should be protected, streets
should be swept as needed when sediment is present, and erosion
control measures removed or damaged by sub -contractors or
utilities shall be re -installed at the end of the work day.
10.Details for silt fence, silt fence outlet, construction entrance and
other measures are provided on other sheets.
11. Erosion control details are not drawn to scale.
12.If lots are contiguous and have different land owners, lots can not
share the silt fences. Each lot should have individual silt fences.

Consult S&EC Environmental Engineers for additional information concerning other alternatives for vegetation
of denuded areas. The above vegetation rates are those that do well under local conditions; other seeding rate
combinations are possible.
- TEMPORARY: Reseed according to optimum season for desired permanent vegetation. Do not allow
temporary cover to grow more than 12" in height before mowing; otherwise, fescue may be shaded out.
3. Remove all loose rock, roots and other obstructions, leaving surface reasonably smooth and uniform-
4. Apply agricultural lime, fertilizer and superphosphate uniformly and mixwith 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.
S. Inspect all seeded areas and make necessary repairs or reseedings within the planting season, if possible. If
stand should be more than 60% damaged, re-establish following the original lime, fertilizer and seeding
