Post Office Box 8005
Cary, NC 27512-8005
Dear Mr. Brown:
You have our approval, in accordance with the attached conditions, to temporarily impact in 3.01 acres of
wetlands or waters for the purpose of sewer line installation at Lynn Branch, as you described in your
application dated October 9, 1997. After reviewing your application, we have decided that this fill is covered
by General Water Quality Certification Numbers 3101 & 3114. These Certifications allows you to use
Nationwide Permit Numbers 12 & 33 when it is issued by the Corps of Engineers. In addition, you should get
any other federal, state or local permits before you go ahead with your protect including (but not limited to)
Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations.
Also this approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified
in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you
change your project, you must notify us and you may be required to send us a new application. If total
wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required
as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed
in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing.
You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written
petition which conforms to Chapter 150E of the North Carolina General Statutes to the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are
final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone John Dorney at 919-733-1786.

Re: Lynn Branch sewer replacement, Lochmere Lake, Cary, Wake County NC
Dear Mr. Alsmeyer:
Enclosed is a PCN and supporting documentation for permitting the above referenced
project, which will have no permanent impacts to waters or wetlands, but will temporarily
affect 2.91 acres of non-wetland waters (lake bottom) by excavation or fill, and will
temporarily drain about 50 non-wetland acres of the lake and less than 0.1 acre of marsh
wetland by lowering the lake level for several months. The Town of Cary plans to begin
construction in December or January, and hopes to refill the lake by May, before the onset
of hot weather.
We are sending simultaneously seven copies of this PCN and report to John Dorney
(DWQ) and one each to Candace Martino (FWS) and Renee Gledhill-Early (SHPO).
Sincerely,
Gerald B. Pottern, M.Sc.

1.0. PROJECT DESCRIPTION.
The Town of Cary is proposing to replace 4,050 feet of the existing 21 inch diameter
Lynn Branch interceptor sewer in the Lochmere subdivision. The existing interceptor is
located 10 to 20 feet from the eastern shore of Lochmere Lake in southwestern Wake
County, N.C. The replacement sewer will be installed between the existing line and the lake
shore. To minimize disturbance of adjoining lawns and landscaping, the lake level will be
drawn down approximately 11 feet below normal pool elevation, and a temporary gravel road
constructed on the exposed lake bed to provide access for construction equipment. The
gravel will be placed over a layer of fabric to facilitate removal when construction is
completed. At that time, the lake bed will be restored to its pre-construction grade and the
lake refilled.
2.0. EXISTING CONDITIONS.
2.1. Fish and Aquatic Habitats.
Lochmere Lake is an impoundment of Lynn Branch, a tributary of Swift Creek in the
Neuse River basin. The drainage basin area at the dam is 3.5 square miles, maximum depth
is 22 feet, and the lake covers approximately 80 acres at a normal pool elevation of 337 feet
NGVD. Fishes observed during the field reconnaissance or reported by residents are
warmwater species including largemouth bass (Micropterus salmoides), bluegill (Lepomis
macrochirus), carp (Cyprinus carpio), eastern mosquitofish (Gambusia holbrooki), channel
catfish (lctalurus punctatus), golden shiner (Notemigonus crysoleucas), and johnny darter
(Etheostoma nigrum). Muskrat middens on the shoreline contained shells of two species of
bivalve mollusks, the Asian clam (Corbicula f/uminea) and the eastern floater (Anodonta
cataracta). The lake substratum is comprised of clay, silt, and sand in the northern half, and
silt, sand, and gravel in the southern portion. Shoreline shrubs and saplings include tag alder
(Alnus serrulata), red maple (Acer rubrum), wax myrtle (Myrica cerifera), and buttonbush
(Cephalanthus occidentalis) along the few segments that are not mowed or bulkheaded. No
submersed or emergent aquatic vegetation beds are present, and woody debris is sparse.
Available cover for fish is limited to boat docks and undermined bulkhead walls.
2.2. Wildlife and Terrestrial Habitats.
The eastern shore of Lochmere Lake is predominantly residential with cultivated grass
lawns and widely spaced trees. Such areas have minimal value as wildlife habitat and native
animals are subject to predation by domestic cats and dogs. A few undeveloped lots are
partially wooded and provide habitat diversity, but their small size and wide spacing limits
their wildlife value. Wildlife species in these areas include house sparrow (Passerdomesticus),
cardinal (Cardinafis cardinafis), robin (Turdus migratorius), Carolina wren (Thryothorus
ludovicianus), mourning dove (Zenaida macroura), tufted titmouse (Parus bicolor), raccoon
(Procyon lotor), eastern cottontail (Sylvilagus floridanus), grey squirrel (Sciurus carolinensis),
and white tailed deer (Odocoileus virginianus). Feeding evidence of beaver (Castor
canadensis) and muskrat (Ondatra zibethicus) was found along the shore.
The extreme northern end of the lake, where Lynn Branch enters, has accumulated
sediment and contains muddy shallows with a narrow fringe of marsh wetland. Shrubs and
3
sapling trees in the marsh include tag alder, river birch (Betula nigra), and black willow (Sa/ix
nigra), and herbs include water primrose (Ludwigia spp.), smartweed (Polygonum spp.), false
nettle (Boehmeria cylindrica), duck potato (Sagittaria latifolia), and jewelweed (Impatiens
capensis). This area supports resident and migratory waterfowl and wading birds including
mallard (Areas platyrhynchos), domesticated ducks, mute swan (Cygnus olor), great blue heron
(Ardea herodias), green heron (Butorides striatus), and spotted sandpiper (Actitis macularia).
2.3. Jurisdictional Waters and Wetlands.
RJG&A ecologists Gerald Pottern and Martha Brewster surveyed the proposed
construction corridor for jurisdictional wetlands on September 15, 1997, using the 1987
Corps of Engineers (COE) Wetlands Delineation Manual (Environmental Laboratory, 1987),
subsequent COE Regulatory Guidance Letters, and supplementary technical literature for
hydrophytic vegetation, hydric soils, and hydrology indicators.
There are no jurisdictional wetlands in the proposed construction corridor. A small
marsh wetland (less than 0.1 acre, described in Section 2.2) occurs at the head of the lake
1,800 feet upstream of the construction area.
The lake area inundated at normal pool elevation constitutes jurisdictional non-wetland
waters. Construction requiring fill or excavation in jurisdictional waters or wetlands must be
permitted through COE and the N.C. Division of Water Quality (DWQ), in accordance with
Sections 404 and 401 of the federal Clean Water Act (see Section 3.2).
2.4. Protected Species.
The Natural Heritage Program (NHP) has records of 27 protected species from Wake
County (February, 1997). Two vertebrates, one river mussel, and one plant are federally
endangered (E) or threatened M. The remaining 23 species are state protected (E, T, or
special concern (SC), including eleven vertebrates, seven river mussels, and five plants (Table
1). Habitat requirements of each protected species and the presence or absence of suitable
habitat in the project area are summarized in Table 2.
RJG&A ecologists Gerald Pottern and Martha Brewster surveyed the proposed
construction area for protected species and their habitats on September 15, 1997. No
protected species were observed during the field reconnaissance. There is no potential habitat
for any of these species in the construction area. The sewerline replacement will have no
direct impacts on protected species.
3.0. IMPACTS AND RECOMMENDATIONS
3.1. Fish and Wildlife Habitat.
At the proposed drawdown to 326 feet NGVD, Lochmere Lake will be reduced to 30
acres and a maximum depth of 10 feet, based on Wake County topographic mapping prior to
construction of the lake. If much silt has accumulated near the dam since impoundment, the
maximum depth may be shallower. The N.C. Wildlife Resources Commission and N.C.
4
Cooperative Extension Service recommend that most of the area in fish ponds should be 6 to
8 feet deep for protection against thermal extremes and overgrowth of aquatic weeds.
Depths in excess of 10 to 12 feet provide no additional benefit. Roughly half of the reduced
lake pool will be 6 feet or deeper at the proposed water elevation.
The 6 to 8 foot depth recommendation is based on the observation that most small
lakes and ponds in central North Carolina usually stratify at a depth of 4 to 5 feet during late
spring and summer. The surface waters (above the thermocline) may reach temperatures
above 90°F that are stressful to warmwater fish, and the bottom waters (below the
thermocline) may become oxygen deficient if stratification is persistent. Heavy rains, wind,
and prolonged cloudy weather may periodically disrupt stratification, cooling the surface
waters and re-oxygenating the bottom waters.
Fish will be concentrated during the drawdown. Depending on the current fish density
in the lake, some may die from crowding effects and many will be eaten. To minimize
adverse impacts on fish and promote recovery of the recreational fishery when the lake is
refilled, we recommend that water depths be checked by boat following drawdown to ensure
that a major portion of the remaining pool is at least 6 feet deep. If silt has rendered most of
the pool much shallower than this, fish mortality may occur if the lake is not refilled before
the onset of hot weather next year. The safest course of action would be to complete
construction and refill the lake by early May. If warm weather construction is unavoidable,
periodic profiles of temperature and dissolved oxygen would be useful for identifying critical
conditions, when electric or gas-powered aerators could be used. If significant fish mortality
due to heat, low oxygen, or disease is observed when the lake level cannot yet be raised, we
advise removing large numbers of fish with large seines or gill nets, to reduce fish density and
the likelihood of a major fish kill.
3.2. Jurisdictional Waters and Wetlands.
The marsh wetland described in section 2.2 is beyond the construction area, but will
be drained during lake drawdown. Herbaceous plants may temporarily die back but will
recolonize from seed or underground structures following refilling of the lake. Shrubs and
saplings in the marsh are not likely to be adversely affected by the drawdown.
The replacement sewerline will cross two bays along the eastern lake shore. The first
crossing is 1,400 feet upstream of the dam and spans 220 feet of open water. The second
is 2,000 feet upstream of the dam and crosses 135 feet of open water. The sewerline will
be buried at least two feet below the lake bed at these crossings to avoid creating an instream
obstruction and to protect it from damage.
Temporary impacts may include elevated turbidity and sediment deposition in Lochmere
Lake resulting from land disturbance during road construction, sewer installation, and road
removal. An erosion and sedimentation control plan must be submitted to the DEHNR Raleigh
Regional Office for approval at least 30 days prior to construction.
Two aspects of the project will require Section 404/401 permitting: 1) permanent
installation of the sewerline in 355 feet of the lake bed, and 2) temporary placement of fill for
construction access in 4,000 feet of the lake bed. None of the proposed construction is
within wetlands. COE Nationwide Permit 12 and its corresponding DWQ General Water
5
Quality Certification 3101 authorize excavation and placement of fill in waters or wetlands
for utility line backfill and bedding. COE Nationwide Permit 33 and its corresponding DWQ
General Water Quality Certification 31 14 authorize excavation and placement of fill in waters
or wetlands for temporary construction access and dewatering. These permits can be
combined to authorize a single, complete project, subject to certain conditions imposed by the
COE Chief Engineer (nationwide conditions), the COE Wilmington District Enginner (regional
conditions), and DWQ (401 Certification conditions). The regulatory text and RJG&A's
summary of these permit conditions are appended.
3.3. Protected Species.
No direct impacts to federally or state protected species are likely to occur as a result
of the proposed project, as none occur in the project area.
Several aquatic protected species are known from Swift Creek several miles
downstream of Lochmere Lake (Table 2). Silt from the proposed construction is unlikely to
affect these populations due to intervening impoundments. Nonetheless, appropriate erosion
control measures should be utilized to limit turbidity and sediment loading into Lynn Branch
and Swift Creek below Lochmere Lake, as the cumulative effect of many construction projects
over the past few decades has degraded aquatic habitat in much of the Swift Creek
watershed (N.C. Division of Environmental Management, 1993).
