4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:*
The project area is primarily residential homes and small businesses. The ground surface is generally a mix roadways, shoulders, and adjacent vacant grassy and wooded areas. The
project involves replacement of existing sewer lines and manholes within the Maple Street / Merritt Street area within the City of Mount Airy. As part of the construction, two gravity sewer
line stream crossings would be required. The stream is an un -named tributary to Lovill Creek. The stream crossings would be completed by open cut and the sewer line would be
concrete encased below streambed level.

4f. List the total estimated acreage of all existing wetlands on the property
4g. List the total estimated linear feet of all existing streams on the property:
550 +/- LF
4h. Explain the purpose of the proposed project:*
The Project is proposed to address improvements needed to the City's existing sewage collection system serving the Maple Street and Merritt Street Areas. The Maple/Merritt Street
area is currently served by the City's gravity sewer system. The existing gravity sewer lines are 8" and 6" terra cotta material, believed to have originally been installed over 60 years
ago. The existing sewer lines have proven to be problematic, subject to frequent pipe blockages - so teh lines are being replaced.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The recommended course of action is to complete the proposed stream crossing by open cut and concrete encasement of the pipe below streambed level. The contractor will maintain
stream flow by using either a temporary flume pipe or a bypass pump. After the sewer pipes and concrete encasement are installed, the streambed will be restored to original profile.

Task 4: REGULATORY PERMITS: Following receipt of any Preliminary Design review comments, TLG will revise
the plans as needed and prepare the permit application forms for those permits necessary to complete
construction. It is anticipated that permits will be required from NCDEQ Division of Water Resources
(Wastewater Collection System Construction Permit), NCDEQ Land Quality Section (Erosion & Sediment
Control Plan), NCDOT (Highway Encroachment), and Yadkin Valley Railroad.
Task 5: ADDITIONAL ENGINEERING SERVICES: Additional engineering services would include those work tasks
which may be required, but are typically outside the scope of Basic design services. Some items which could
be considered to be Additional Services include:
i) identification and denotation of any necessary right-of-way easements needed for the construction and
will be indicated on the plans provided to the City's Attorney. The City will be responsible for
preparing the appropriate easement documents, securing landowner signatures, and recording the
easements.
ii) Preparation of the Environmental Review Document and assisting the City with the Request for
Release of Funds process. The CDBG-I program requires funded projects to complete an
Environmental Review process in order to demonstrate that the project will not have a significant
negative effect upon the environment. The Environmental Review process includes contacting those
environmental review clearinghouses required by the CDBG program and requesting comments upon
the project, addressing any comments received, documenting clearance, and assembling all
information into the Environmental Review document that will ultimately be reviewed and approved
by CDBG representatives.
iii) As part of this Proposal, TLG is requested to include payment of the required regulatory permitting
fees and this would be considered to be an Additional service. Following is an estimate of the
permitting fees anticipated for the project:
NCDENR DWR (Wastewater Construction Permit) .... $480 permit + 15% Markup .............$552
NCDENR LQ (Erosion Control) .................................. $325 permit + 15% Markup .............$374
Yadkin Valley Railroad ................................................ $1,500 permit+ 15% Markup .......$1,725
Task 6: PROJECT BIDDING ASSISTANCE: TLG will assist the City in procuring a contractor to complete
construction. Project bidding assistance includes preparation of the newspaper advertisement identification
and notification of at least four (4) local qualified contractors, preparation and distribution of bid sets,
conducting a Pre -Bid Conference, answering Contractors' questions and issuing Addendums (if required),
attending the Bid Opening, tabulating the bid results, and making a recommendation of award to the City.
Task 7: CONSTRUCTION ADMINISTRATION: Construction Administration services to be provided include
preparation and review of construction contract documents (agreement forms, bonds, certificates of insurance),
conducting a preconstruction conference, review and approval of shop drawings, interpretation of plans and
specifications during the construction period, attend monthly progress meetings to review the work progress
made, review/approve Contractor pay requests, and prepare any necessary Contract Change Order forms for
approval. This task also includes preparation of As -Built Record Drawings using field sketches and/or
markups completed by the RPR and/or the Contractor in addition to GPS survey locates completed by the City.
Task 8: RESIDENT PROJECT REPRESENTATIVE SERVICES: During the construction period, TLG will provide
resident project representative (RPR) services. The RPR assigned to the project will monitor construction at
time intervals and frequencies determined to be necessary to reasonably assure Contractor compliance with the
plans, specifications, and permit requirements. Following completion of construction, a final inspection will be
held with representatives of the City, TLG, the Contractor, and other agencies as appropriate. A statement of
Substantial Completion will be issued to NCDEQ-DWQ once all work is completed in conformance with the
plans and specifications. For budgeting purposes, a total time allocation of twenty-four (24) 40 -hour weeks
have been estimated for periodic inspections.

Re: Merritt Street and Maple Street Sewer Improvements, Mount Airy, Surry County, ER 18-3585
Dear Ms. Tate:
Thank you for your email of November 7, 2018, regarding the above-referenced undertaking. We have
reviewed your submittal and offer the following comments.

Portions of the project are within the Mounty Airy Historic District - Boundary Increase II (SR1108) which
was placed on the State Study List in 2018. As proposed, the sewer line replacement and other improvement
activities will have no adverse effect on the district.

There are no known archaeological sites within the proposed project area. Based on our knowledge of the
area, it is unlikely that any archaeological resources that may be eligible for inclusion in the National Register of
Historic Places will be affected by the project. We, therefore, recommend that no archaeological investigation
be conducted in connection with this project.

The above comments are made pursuant to Section 106 and 110 of the National Historic Preservation Act and
the Advisory Council on Historic Preservation’s Regulations for Compliance with Section 106 codified at 36
CFR Part 800.

Thank you for your cooperation and consideration. If you have questions concerning the above comment,
contact Renee Gledhill-Earley, environmental review coordinator, at 919-814-6579 or
[e-mail]. In all future communication concerning this project, please cite the above
referenced tracking number.

species or their habitats occur in the project area. Therefore, we believe the requirements under
section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be
reconsidered if: (1) new information reveals impacts of this identified action that may affect
listed species or critical habitat in a manner not previously considered, (2) this action is
subsequently modified in a manner that was not considered in this review, or (3) a new species is
listed or critical habitat is determined that may be affected by the identified action.

We appreciate the opportunity to provide these comments. If we can be of assistance or if you
have any questions, please contact Mr. Allen Ratzlaff of our staff at 828/258-3939, Ext. 229. In
any future correspondence concerning this project, please reference our Log Number 4-2-19-062.

CONSTRUCTION SEQUENCE
1. KEEP CLEARING AND EXCAVATION OF THE STREAM BANKS, BEDS, AND APPROACH SECTIONS TO A MINIMUM. LIMIT THE CONSTRUCTION TIME FOR CROSSING
THE STREAM TO THE ABSOLUTE MINIMUM REQUIRED. DO NOT BEGIN WORK ON STREAM CROSSING LATE IN THE DAY OR WEEK OR WHEN BAD WEATHER IS
FORECAST.
2. DO NOT CONSTRUCT A BYPASS CHANNEL FOR ANY CREEK CROSSING. TO WORK WITHIN THE LIMITS OF THE STREAM BANK: 1.) FIRST INSTALL DIVERSION
DAMS MADE OF SAND BAGS, SAND BAGS BACKED BY RIPRAP, OR SHEET PILING IN THE INITIAL WORK AREA OF STREAM TO KEEP FLOWING WATER AWAY FROM
WORK AREA; 2.) AFTER PIPE IS INSTALLED IN THE INITIAL WORK AREA, USE RIPRAP TO PROPERLY STABILIZE DISTURBED EXCAVATION AREA; 3.) RECONSTRUCT
DIVERSION TO DE-WATER THE REMAINDER OF THE PIPE CROSSING. ANY AREA OF STREAM BED EXCAVATED MUST BE PROPERLY STABILIZED WITH RIPRAP
PRIOR TO RESUMING NORMAL STREAM FLOW.
3. LIMIT EXCAVATION OF CHANNEL BED TO AREA NECESSARY FOR BURIAL OF PROPOSED PIPE. LINE UNSTABLE STREAM BANKS WITH RIPRAP. AFTER PROJECT
IS COMPLETE, EXCESS RIPRAP MUST BE CAREFULLY REMOVED TO PREVENT FURTHER CHANNEL DISTURBANCE.
4. ANY EXCESS WATER THAT MUST BE PUMPED OUT OF WORK LIMITS MUST BE SPRAYED INTO A STILLING BASIN, OR A COMMERCIALLY AVAILABLE "SILT SACK".
DO NOT PUMP WATER DIRECTLY INTO STREAM. PROPER CHECK DAMS MUST BE CONSTRUCTED TO CONTROL RUNOFF FROM SPRAY AREAS.
5. KEEP STREAM CROSSINGS AT RIGHT ANGLES TO THE STREAM FLOW AND ALIGN THE ROAD WITH THE CENTER LINE OF THE CROSSING FOR A MINIMUM
DISTANCE OF 30 FT.
6. STABILIZE ALL DISTURBED AREAS SUBJECT TO FLOWING WATER (INCLUDING PLANNED OVERFLOW AREAS) WITH RIPRAP OR OTHER SUITABLE MEASURES.

FINAL DRAWING - FOR REVIEW PURPOSES ONLY - NOT RELEASED FOR CONSTRUCTION
GENERAL EROSION AND SEDIMENT CONTROL NOTES:
1.Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will
be constructed and maintained according to minimum standards and specifications of the North
Carolina Erosion and Sediment Control Planning and Design Manual (NCES CPDM).
2.The plan approving authority must be notified one week prior to the preconstruction conference, one
week prior to the commencement of land disturbing activity, and one week prior to the final
inspection.
3.All erosion and sediment control measures are to be placed prior to or as the first step of land
disturbance.
4.A copy of the approved erosion and sediment control plan (if applicable) shall be maintained on the
site at all times.
5.Prior to commencing land disturbing activities in areas other than indicated on these plans
(including, but not limited to, off-site borrow or waste areas), the contractor shall submit a
supplementary erosion and sediment control plan as determined by the plan approving authority.
6.The contractor is responsible for installation of any additional erosion control measures necessary to
prevent erosion and sedimentation as determined by the plan approving authority.
7.The proposed utility lines shall not be installed directly beneath any ditch in order to minimize
erosion. The proposed lines shall be installed in the shoulder or slope beyond.
8.The Owner, Engineer, Inspector, Local Building Official, or NCDENR reserve the right to require
erosion control measures in addition to those shown if conditions warrant in order to address
erosion.
9.All disturbed areas are to drain to approved sediment control measures at all times during land
disturbing activities and during site development until final stabilization is achieved.
10.For disturbed area calculations, a disturbed area of 10 feet width has been used for proposed water
lines and the indicated areas on the plans. The total area of disturbance is estimated to be 0.63
acres.
11.The Contractor shall inspect all erosion control measures no less than every 7 calendar days and
after each runoff-producing rainfall event producing 1/2 inch of precipitation or greater. Any
necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be
made immediately.
12.This sheet is for Erosion control measures only. See other plan sheets for detailed construction
information.
13.All disturbed and unpaved areas are to be seeded and mulched.
14.All slopes disturbed in excess of 10% and ditches shall be mulched with erosion control matting,
properly anchored.
15.Following project completion and stabilization, all temporary erosion control measures shall be
cleaned up/removed.
16.The contractor shall limit the area of disturbance along proposed utility lines to the maximum width
indicated in Note ES-10 unless noted otherwise.
17.During dewatering operations, water shall be pumped into an approved filtering device.
18.A permanent vegetative cover shall be established on all denuded areas not otherwise permanently
stabilized. Permanent vegetation shall not be considered established until a ground cover is
achieved that, in the opinion of the local program administrator or his designated agent, is uniform,
mature enough to survive, and will inhibit erosion.
19.The Contractor shall clean sediment from any sediment trapping device when sediment buildup
reaches the cleanout elevation.
20.Refer to the NCESCPDM for installation requirements for any measure(s) required that are not
detailed on the erosion and sediment control detail sheets.
21.Underground utility lines shall be installed in accordance with the following standards in addition to
other applicable criteria:
a.Not more than 500 LF of trench may be open at any time.
b.Excavated material shall be placed on the uphill side of trenches.
c.Effluent from dewatering operations shall be filtered or passed through an approved sediment
trapping device, or both, and discharged in a manner that does not adversely affect flowing
streams or off-site property.
d.Material used for backfilling trenches shall be properly compacted in order to minimize erosion
and promote stabilization.
22.Soil stabilization shall be achieved on any area of a site where land-disturbing activities have
temporarily or permanently ceased according to the following schedule:
a. All perimeter dikes, swales, ditches, perimeter slopes and all slopes steeper than three (3)
horizontal to one (1) vertical (3:1) shall be provided temporary or permanent stabilization with
ground cover as soon as practicable but in any event within 14 calendar days from the last
land-disturbing activity.
b. All other disturbed areas shall be provided temporary or permanent stabilization with ground
cover as soon as practicable but in any event within 14 calendar days from the last
land-disturbing activity.
VEGETATIVE PLAN:
Seedbed Preparation (SP)
SP1 Fill slopes 3:1 or steeper to be seeded with a hydraulic seeder (permanent seedings)
1.Leave the last 4-6 inches of fill loose and uncompacted, allowing rocks, roots, large clods
and other debris to remain on the slope.
2.Roughen slope faces by making grooves 2-3 inches deep, perpendicular to the slope.
3.Spread lime evenly over slopes at a rate of 4000 lb/acre.
SP2 Fill slopes 3:1 or steeper (temporary seedings)
1.Leave a loose, uncompacted surface. Remove large clods, rocks, and debris which might
hold netting above the surface.
2.Spread lime and fertilizer evenly at a rate of 4000 lb/acre (lime) and 1000 lb/acre (5-10-10
fertilizer).
3.Incorporate amendments by roughening or grooving soil surface on the contour.
SP3 High-maintenance turf
1.Remove rocks and debris that could interfere with tillage and the production of a uniform
seedbed.
2.Apply lime and fertilizer at a rate of 4000 lb/acre (lime) and 1000 lb/acre (10-10-10
fertilizer); spread evenly and incorporate to a depth of 2-4" with a farm disk or chisel plow.
3.Loosen the subgrade immediately prior to spreading topsoil by disking or scarifying to a
depth of at least 2 inches.
4.Spread topsoil to a depth of 2-4 inches and cultipack.
5.Disk or harrow and rake to produce a uniform and well-pulverized surface.
6.Loosen surface just prior to applying seed.
SP4 Gentle or flat slopes where topsoil is not used
1.Remove rocks and debris.
2.Apply lime and fertilizer at a rate of 4000 lb/acre (lime) and 1000 lb/acre (10-10-10
fertilizer); spread evenly and incorporate into the top 6" with a disk, chisel plow, or rotary
tiller.
3.Break up large clods and rake into a loose, uniform seedbed.
4.Rake to loosen surface just prior to applying seed.
Seeding Methods (SM)
SM1 Fill slopes steeper than 3:1 (permanent seedings)
1.Use hydraulic seeding equipment to apply seed and fertilizer, a wood fiber mulch at 45

SM2 Gentle to flat slopes or temporary seedings
1.Broadcast seed at the recommended rate with a cyclone seeder, drop spreader, or
cultipacker seeder.
2.Rake seed into the soil and lightly pack to establish good contact.
Mulch (MU)
MU1 Steep slopes (3:1 or greater)
1.In mid-summer, late fall or winter, apply 4000-5000 lb/acre grain straw cover with netting
and staple to the slope. In spring or early fall use 45 lb/1,000 sq. ft. wood fiber in a
hydroseeder slurry.
MU2 High-maintenance vegetation and temporary seedings
1.Apply 90 lb/1,000 sq. ft. (4000 lb/acre) grain straw and tack with 0.1 gal/sq. yard asphalt (11
gal/1,000 sq. ft.).
MU3 Grass-lined channels
1.Install excelsior mat in the channel, extend up the channel banks to the highest calculated
depth of flow, and secure according to manufacturer's specifications. On channel
shoulders, apply 100 lb/1,000 sq. ft. grain straw and anchor with 0.1 gal/sq. yard (11
gal/1,000 sq. ft.) asphalt.
Maintenance (MA)
MA1 Refertilize in late winter or early spring the following year. Mow as desired.
MA2 Keep mowed to a height of 2-4 inches. Fertilize with 40 lb/acre(1 lb/1,000 sq. ft.) nitrogen
in winter and again the following fall.
MA3 Inspect and repair mulch and lining. Refertilize in late winter of the following year with 150
lb/acre 10-10-10 (3.5 lb/1,000 sq. ft.). Mow regularly to a height of 3-4 inches.
MA4 Topdress with 10-10-10 fertilizer if growth is not fully adequate.
MA5 Topdress with 50 lb/acre (1 lb/1,000 sq. ft.) nitrogen in March. If cover is needed through
the following summer, overseed with 50 lb/acre Kobe lespedeza.

1.LAY ONE BLOCK ON EACH SIDE OF THE STRUCTURE ON ITS SIDE ON THE BOTTOM ROW TO ALLOW
POOL DRAINAGE. THE FOUNDATION SHOULD BE EXCAVATED AT LEAST 2 INCHES BELOW THE
CREST OF THE STORM DRAIN. PLACE THE BOTTOM ROW OF BLOCK AGAINST THE EDGE OF THE
STORM DRAIN FOR LATERAL SUPPORT AND TO AVOID WASHOUTS WHEN OVERFLOW OCCURS. IF
NEEDED, GIVE LATERAL SUPPORT TO SUBSEQUENT ROWS BY PLACING 2x4 WOOD STUDS THROUGH
BLOCK OPENINGS. CAREFULLY FIT HARDWARE CLOTH OR COMPARABLE WIRE MESH WITH 1-1/2.
2.INCH OPENING OVER ALL BLOCK OPENINGS TO HOLD GRAVEL IN PLACE.
