§ 7.5-92. Plans; specifications; submittals.

(1)

Generally. All projects which involve construction of main sewers and/or force mains, pumping facilities, and private sewerage systems shall have detailed construction plans and specifications prepared by a registered professional engineer or licensed surveyor licensed in the state. Developments which only involve building sewers may have plans and specifications prepared by the project architect.

(2)

Preliminary review. Preliminary plans will be prepared and submitted for review as described elsewhere in the development regulations. Questions relating to availability of sewers and proposed location of connection should be resolved at this stage before proceeding with final planning. A submittal for preliminary review must include all land to be developed although the land is to be developed in several phases or units. Availability determinations will be made only for the phases of the project proposed for current construction. Availability determinations will be valid for a period of one (1) year from the date of project approval. The developer must submit any data required for accurately projecting sewer flow quantities and rates. The developer is also responsible for furnishing any other information deemed necessary for evaluating service feasibility.

(3)

Sewer construction plans. All plans for public and private sewer facilities shall be prepared in accordance with the requirements outlined herein and as required in regulations promulgated by the Georgia Environmental Protection Division. The developer shall be responsible for submitting plans and other data to the state EPD for required approvals. Projects involving sewers greater than thirty-six (36) inches in diameter or pump stations with capacity of seven hundred (700) gallons per minute and greater must be submitted to the EPD for required approvals. The following requirements will apply to preparation of sewer construction plans:

(a)

The site plan shall show land lots, district and north arrow, lot layout, and existing and proposed building locations. The site plan shall also show all existing and proposed streets and their names, all streams, water courses, existing and proposed storm drains, and the discharge points for all drainage structures. The site plan shall accurately show the topography with contour lines at two-foot intervals. Elevations shall be referenced to mean sea level and plans shall note the location of the specific USGS vertical elevation marker or other approved benchmark used for deriving site elevations. The site plan shall show the sewer layout with existing and proposed lines, manhole numbers, line designation and direction of flow, and proposed sewer easements and other utility easements. It shall also show the location of proposed services.

(b)

The design of cross-country sewer lines and force mains shall be based on field-run surveys. The site plan for cross-country sewer lines and force mains need not show contour intervals on the plan view, but the profile views shall accurately depict ground level elevations and elevations of all relevant structures. Site plans for lift stations shall show existing and proposed contours. In the event the subdivision is developed in phases, the final construction plans for sewers may be submitted in phases or units. However, at the time the first phase is submitted, the engineer will submit one (1) copy of the preliminary layout of the entire sewer system. This layout will show all lines required to serve any lots to be developed and any surrounding property that may be served through the property. The site plans for each phase or unit shall contain a location drawing showing the relationship of the phase or unit to the total project and to the surrounding streets and sewers.

(c)

Profiles should have a horizontal scale of not more than one hundred (100) feet to the inch for cross-country lines and fifty (50) feet to the inch for congested areas, and a vertical scale of not more than twenty (20) feet to the inch. The plan view should be drawn to a corresponding horizontal scale. The plan view should normally be shown on the same sheet as the profile. In any case both the plan and profile view should have line designations, station numbers, manhole numbers and any other indexing necessary to easily correlate the plan and profile view. Plans and profiles shall show:

1.

Location of streets, sewers and utility easements.

2.

Profile of ground surface, the grade of the sewer between each two (2) adjacent manholes, size and material of pipe, length between manholes, invert of sewer in and out of each manhole, and ground surface elevation at each manhole. All manholes shall be numbered on the plan and correspondingly numbered on the profile and station numbers will be shown for each manhole. The profile of adjacent parallel stream beds and of adjacent lake surfaces, low buildings, and lots shall be shown on the profile.

3.

Locations of all special features such as connection to existing sewers, concrete encasements, collar walls, ductile iron pipe sections, elevated sewers, piers, special manhole covers such as vented outfall covers or sealed covers, etc.

4.

All known existing structures both above and below ground which might interfere with the proposed construction, particularly water mains, gas mains, storm drains, utility conduits, etc.

5.

The vertical datum used shall be the elevation above mean sea level with benchmarks shown on the plans.

(4)

Erosion and sedimentation control plan.

(a)

The Georgia Soil and Water Conservation Commission has taken provisions of ACT 599 and published the Manual for Erosion and Sediment Control in Georgia, 1992 edition (or any more current edition as they are published and/or amended). Sewer construction plans and specifications shall include appropriate segments of this manual. Developers, engineers and contractors performing work in the city are responsible for acquiring a copy of this manual and using the best practical methods contained therein to control the erosion and sedimentation of the construction site in conformance with the intent of ACT 599. Copies may be purchased from the Georgia Soil And Water Conservation Commission, P.O. Box 8024, Athens, Georgia 30603. For additional information, call the commission at 706-542-3065.

(b)

An erosion and sediment control plan, meeting the requirements of applicable state regulations, shall be provided as part of the overall construction drawings.

(5)

Detail drawings.

(a)

Sewer details. Special detail drawings made to a scale to clearly show the nature of the design shall be furnished to show the following particulars:

1.

All stream crossings and storm drain outlets with elevations of the stream bed and of normal and extreme high and low water levels.

2.

Details of special sewer joints and cross sections.

3.

Details of special sewer appurtenances such as manholes, service connections, elevated sewers, piers, pipe bedding, special highway crossings, railroad crossings, etc.

(b)

Erosion control details. Erosion control details and symbols may be taken directly from the Manual for Erosion and Sediment Control in Georgia, 1992, referenced above.

(6)

As-built drawings. At the completion of construction (and preferably prior to the final field inspection), "as-built" drawings of the project shall be submitted to the city to serve as a permanent record of the project and shall be furnished in the form of one (1) set of mylar sepias (or other suitable form of reproducible drawings) and two (2) sets of blue line copies. Acceptance by the city will be made only after satisfactory as-built drawings have been submitted. As-built drawings will be in the same format as the original construction plans and normally will be an updated version of the construction plans. As-built drawing shall be prepared by the project design professional. Each sheet of these drawings shall bear the words "as-built" or "record drawings." Guidelines for preparation of as-builts:

1.

As-built drawings will be in the same format as the original construction plans.

2.

Contour lines are required.

3.

Road names and lot numbers should be on plan.

4.

"As-built" or "record drawing" is to be stamped in large clear print on plans.

5.

Sheet should be no larger than twenty-four (24) inches × thirty-six (36) inches.

6.

Lateral locations must show distance from the downstream manhole. Ends of lateral lines must show distance from downstream manhole and offset distance from the main line. Approximate depth of end of lateral must be indicated.

7.

Show elevations of manhole inverts and tops.

8.

Show field-measured distance between manholes.

9.

For any lines which are outside paved streets, show the field-measured azimuth or bearing of the line from manhole to manhole.

10.

Show actual slope of pipe.

11.

When a phase of a subdivision is completed, a location sketch of entire subdivision with said phase outlined shall appear on plans.

12.

Maximum error of as-built measurements shall be:

a.

Manhole inverts: measure to one-tenth (0.10) feet with maximum vertical error of one-fifteenth (0.15) feet per one thousand (1,000) feet of horizontal traverse.

b.

Manhole tops: measure to one-tenth (0.10) feet with maximum vertical error of one-half (0.50) feet per one thousand (1,000) feet of horizontal traverse.

c.

Horizontal locations: Measure to nearest one (1.0) foot with allowable error of one (1.0) foot per one thousand (1,000) feet of traverse.

(7)

Easement acquisition and utility encroachment permits.

(a)

It shall be the responsibility of the developer to obtain any off-site easements required to connect the project to existing public sewers. Easements will be conveyed to the city for all facilities which are to be conveyed to the city. This process must be started early enough to allow construction of the sewer before any building construction is to begin. No building permits or sewer tap applications can be issued until off-site sewers have been constructed and accepted. This condition shall override any provision for speed up of house starts such as furnishing a bond to guarantee completion of the streets and other appurtenances.

(b)

All easements shall allow adequate room to construct the sewer and appurtenances. Permanent easements shall be a minimum of twenty (20) feet wide, ten (10) feet on each side of the line; except that when the depth of the sewer exceeds ten (10) feet the required sewer easement width shall increase such that the easement width is at least twice the depth from the ground surface to bottom of the pipe. Designs involving utilities sharing a common easement will be coordinated with the utilities to insure adequate separation of utilities and overall easement width is achieved.

(c)

Easement drawings for work outside the development shall be furnished and recorded prior to approval of the sewer plans. The drawings shall be of a size suitable for legal recording and shall be prepared by a state registered land surveyor. The drawing will show property lines, the name of property owners with the length of line encroaching on each property owner, size of line, line designation, manhole numbers and stations, width of permanent and construction easement, scale of drawing, north arrow, land lot and district numbers, and a tie to the nearest land lot corner. Any streets or other existing easements shall also be shown. The title block shall be shown as follows:

LL: District: Section: Date: Revised Date:

(d)

The engineer shall furnish appropriate drawings for submittal to the appropriate permitting agency of any state or federal highways, railroads, power lines, water lines, gas lines, petroleum lines, or any other utility lines on which the sewer construction will encroach. The drawing shall be eight and one-half (8½) inches × eleven (11) inches and shall show a plan view and profile view. The drawing will show the same information required for easement drawings. Also, the drawing will show the right-of-way of the existing street or utility, the owner's designation of the line, the name or number of the nearest intersection or mile post or tower number and the distance to that appurtenance. The clearance distance between the street surface, or the bottom of the rail, or the utility and the sewer will be shown. The drawing will show the type of material to be used for the sewer and the method of construction to be used. The drawing will also contain any other special information required by the controlling authority of the facility on which the sewer is encroaching. A minimum of five (5) copies of the utility encroachment drawing will be furnished with the plans when they are submitted for approval. The engineer is also responsible for furnishing a completed encroachment permit application ready for signature by department superintendent. Construction permits will not be issued until the utility encroachment permit has been obtained and until any special conditions such as insurance requirements have been complied with.
