Remarks Annette - I spoke with Amy Chapman about this revisions earlier today. The developer has
changed the lot layout to avoid a gas line and as a result, I have modified the calculations. The updated

Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
- Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
- Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
- Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
- Once a year, the soil will be aerated if necessary.
- Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Temporary seeding shall be in accordance with temporary seeding specifications.
Seadbed 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.
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 reseedings within 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.

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.
Required Wake County Construction Sequence:
1. Schedule a preconstruction conference with the Environmental Engineer, Debra Greene at
919- 842 -6215. Obtain a land- disturbing permit.
2. Clear the area needed to construct the proposed construction entrance.
3. Construct the entrance as shown on the plans. Maintain the construction entrance daily
to ensure that mud and silt will not be tracked onto the paved surface. If mud is tracked
onto the surface, it is to be removed immediately.
4. Clear the area needed to construct the perimeter erosion control measures including silt
fence, rocks check dams, temporary diversions, sediment basin, and other measures as
shown on the approved plan. Install proposed devices. Seed temporary diversions, berms and
basins immediately after construction.
5. Call Betsy Pearce for an onsite inspection by the Environmental Engineer to obtain a
Certificate of Compliance.
4. Begin clearing and grubbing. Maintain devices as needed.
5. Rough grade all roadways and parking lots.
6. Construct sanitary sewer system throughout project.
7. Install storm sewer, and protect inlets with block and gravel inlet controls, sediment traps
or other approved measures as shown on the plan. Begin construction,; building, etc.
8. Stabilize site as areas are brought up to finish grade with vegetation, paving, ditch
linings, etc. Seed and mulch denuded areas within fifteen (15) days of completion of any
phase of construction.
See notes and details on D -02 for slope stabilization with matting on 2:1 and 3:1 slopes
(and steeper, as needed during construction).
9. When construction is complete and all areas are stabilized completely, call Betsy Pearce
for an inspection by the Environmental Engineer.
10. If site is approved, remove temporary diversions, silt fence, sediment basins, etc., and
seed out or stabilize any resulting bare areas. All remaining permanent: erosion control
devices, such as velocity dissipators, should now be installed.
11. When vegetation has become established, call for a final site inspection by the
Environmental Engineer, Betsy Pearce. Obtain a Certificate of Completion,
