INFRASTRUCTURE IMPROVEMENTS
This Article sets out the minimum requirements and standards for construction of subdivisions and other land development projects, including general principals of design and layout and requirements for such public facilities as streets and utilities.
Easements other than utility easements shall be required in connection with subdivisions or developments for the following purposes, among others:
Street lights are intended to provide illumination on public streets to a level that provides a reasonably safe and secure operating environment for pedestrian and vehicular traffic within the public right-of-way. Street lights shall not serve as security lighting for private property. Any lighting of private property that results from the public street lighting program is purely circumstantial.
The city does not budget or fund the installation of utility poles or any types of decorative poles for street lighting. It is solely the developer's responsibility to coordinate said installations with the appropriate power company.
All proposed subdivisions, subdivision lots and other land developments shall be provided with driveways or development entrances meeting the following requirements:
Sidewalks shall be installed according to City standards by the developer under the following circumstances:
A.
A sidewalk shall be provided within the right-of-way of any road adjacent to any residential or commercial development. The sidewalks shall be installed at the same time other improvements are installed within the development.
B.
Within a residential subdivision, a sidewalk shall be provided on both sides of every street within the subdivision. A residential subdivision with lots greater than three (3) acres in size is exempt from these requirements.
C.
Sidewalks shall meet the following standards:
1.
In commercial developments, the sidewalk must be at least six (6) feet wide. In residential developments, the sidewalk must be at least five (5) feet wide.
2.
The sidewalk must be located at least four (4) feet from the back of the street curb. The City Engineer may approve a reduction if topographic or other natural features prohibit this separation from the curb.
(Res. No. 05-2019, 1-7-19)
Systems and facilities for the conveyance and control of stormwater shall be designed, installed and maintained subject to the Design and Construction Standards on file in the City Engineer's office and the regulations set forth in Article 7.
A.
Public water service shall be provided to every lot in every subdivision and to every development for both domestic use and fire protection if public water is available or under bid or contract to be available within 1,000 feet of the subdivision or development.
B.
All water system improvements and their installation shall meet the adopted standards of the Carrollton Water and Wastewater Departments. A contractor approved by the City of Carrollton shall install all elements of the water system, including mains, valves, service laterals through the curb line, and fire hydrants at the developer's expense.
A.
Fire hydrants are required in all subdivisions and development projects served by a public water system.
B.
Fire hydrants as specified by the Fire Department and the City of Carrollton shall be located every five-hundred (500) feet and/or at every intersection, whichever is closer.
A.
When in the written opinion of the Carroll County Health Department and the City Engineer, public sanitary sewers are within reasonable access of the subdivision, the subdivider shall provide sanitary sewer services to each lot within the bounds of the subdivision. All sewer service lines in the subdivision shall be installed by the subdivider in accordance with the Design and Construction Standards.
B.
When in the written opinion of the City of Carrollton a public sanitary sewer is not acceptable, an alternate method of sewage disposal for each lot may be used when in compliance with the Carroll County Health Department requirements. A community sewage disposal system may not be used.
C.
Whenever the installation of a sanitary system is required as provided by these regulations, no new street shall be paved without such sewer being first installed in accordance with the requirements of the Georgia Department of Human Resources sewer specifications and the City of Carrollton Design and Construction Standards.
The Design and Construction Standards of the City of Carrollton, also referred to in this UDO as "Design and Construction Standards," as maintained by the City Engineering Department and as may be amended from time to time by said department, are incorporated into this Code as though set forth within the body of this Code. In the case of a conflict between the Design and Construction Standards and the text of this Code, the text of this Code shall control.
The installation of all traffic control signs and street striping shall be governed by the standards contained in the Manual on Uniform Traffic Control Devices, latest edition, published by the Federal Highway Administration of the U.S. Department of Transportation.
Unless otherwise specially set forth in this Code or the Design and Construction Standards, all of the materials, methods of construction, and workmanship for the work covered in reference to street construction and storm drainage construction shall conform to the latest standard specifications of the Georgia Department of Transportation.
Design criteria and standards not specifically set forth herein or in the latest standard specifications of the Georgia Department of Transportation shall conform to the latest edition of the American Association of State Highway and Transportation Officials (AASHTO), "A Policy on Geometric Design of Highways and Streets." The latest edition of the Roadside Design Guide by AASHTO shall be consulted regarding set-back criteria and clear zone distance criteria for structures within a public street right-of-way or private street easement.
The American National Standard Practice for Roadway Lighting of the Illumination Engineering Society, as approved by the American National Standards Institute (1973), or as more recently amended, shall be consulted regarding illumination of public rights-of-way.
A.
Land with a slope of 35% or more, land within an area of special flood hazard (the 100-year floodplain), and land otherwise determined by the City Engineer to be physically unsuitable for subdivision or development because of flooding, poor drainage, topographic, geologic or other such features that may endanger health, life or property, aggravate erosion, increase flood hazard, or necessitate excessive expenditures of public funds for supply and maintenance of services shall not be approved for subdivision or development unless adequate methods are formulated by the developer for solving the problems. Such land shall be set aside for such uses as shall not involve such a danger.
B.
Land within a proposed subdivision or development that is unsuitable for development shall be incorporated into the buildable lots as excess land or set aside as open space. Lots that do not comply with the requirements of this Code are prohibited.
In addition to the requirements established herein, all subdivisions and individual development projects shall comply with the following laws, rules and regulations:
A.
All proposed subdivisions and individual development projects shall conform to the Comprehensive Plan and development policies in effect at the time of submission to the City Engineer.
B.
In subdivisions or developments related to or affecting any State or U.S. numbered highway, the City Engineer shall require the approval of the Georgia Department of Transportation.
C.
Dedications and reservations.
1.
All transportation facilities such as highways, major thoroughfares and other streets shall be platted by the developer in the location and to the dimension indicated on the Comprehensive Plan or the Transportation Plan, whichever is the most recently adopted or amended.
2.
Public facilities other than transportation facilities, such as school sites, park sites, library sites, fire station sites, sites for public utilities or for other public use or open space, shall be shown as dedicated or as reserved on the preliminary and final plats under the following circumstances:
a.
When any of said public facilities are shown in the Comprehensive Plan and located in whole or in part in a proposed subdivision or development; or
b.
When any of said public facilities have not been anticipated by the Comprehensive Plan, but are considered essential to or extremely important to the development of the City or to that neighborhood or portion of the City within which the subdivision or development project lies, by the Carrollton Mayor and City Council.
3.
Time limitation on reservations.
If the developer reserves land for any public facility other than transportation facilities and it is not acquired by gift, purchase, condemnation or otherwise nor optioned by the appropriate public agency within 5 years from the date of recording of the subdivision or by the time Certificates of Occupancy have been issued for 75% of the dwelling units in the development, whichever occurs first, the subdivider may claim the original reservation, or portion thereof, and cause it to be subdivided in a manner suitable to the subdivider subject to the provisions of this UDO.
4.
Waiver of dedication or reservation requirement.
The City Engineer may waive the platting and reservation requirements of subsection (C) above whenever the public body responsible for land acquisition executes a written release stating that such a planned feature is not being acquired.
5.
Refusal of dedication offer.
a.
Whenever a plat or site plan proposes the dedication of land to public use that the City Engineer finds not required or suitable for such public use, the City Engineer shall refuse to approve the plat or site plan. The City Engineer's opinion may be appealed to the Carrollton Mayor and City Council.
b.
Whenever a plat or site plan proposes the dedication of land to public use that the Carrollton Mayor and City Council finds to be not required or suitable for such public use, the Carrollton Mayor and City Council shall refuse to accept the dedication.
The name of each subdivision or development project must have the approval of the City Engineer. The name shall not duplicate nor closely approximate the name of an existing subdivision or development project in the City of Carrollton or Carroll County.
A.
Proposed streets obviously in alignment with other existing and named streets shall bear the names of the existing streets. In no case shall the name for a proposed street duplicate existing street names in the Carrollton area, irrespective of the use of a suffix such as: street, avenue, boulevard, road, pike, drive, way, place, court or other derivatives.
B.
Street names are subject to approval by the City Engineer.
Street addresses shall be obtained from the City Engineer and shall be shown on each final plat.
A.
Residential blocks.
1.
Unless otherwise approved by the City Engineer under unusual circumstances, block lengths shall not exceed 1,800 feet nor be less than 600 feet in length.
2.
In blocks greater than 1,000 feet in length, the City Engineer may require one (1) or more public easements of not less than ten (10) feet in width to extend entirely across the block for pedestrian crosswalks, fire protection or utilities.
3.
Width: Residential blocks shall be wide enough to allow two (2) rows of lots, except where reverse frontage lots on major thoroughfares are provided, or when prevented by topographic conditions or size of the property, or for lots along the periphery of the subdivision, or where abutting upon limited access highways or railroads, or where other situations make this requirement impractical, in which case the City Engineer may approve a single row of lots.
B.
Non-Residential blocks.
Blocks for other than residential use shall be of such length and width as may be suitable for the prospective use, including adequate provision for off-street parking and service.
A.
Minimum lot dimensions and areas.
All lots shall meet or exceed the area and dimensional requirements of this UDO for the zoning district and type of development in which the lots are located. Lot size may be reduced by the Mayor and City Council if approved as a Planned Development.
B.
Authority of Health Department.
Nothing contained in this Article shall be construed as preventing the Carroll County Health Department, after study of the conditions existing in a proposed subdivision, from requiring that all or any portion of the area of such subdivision shall not be built upon or that the minimum lot sizes set forth in this Development Ordinance are inadequate and must be increased to ensure the protection of the public health.
C.
Adequate building sites.
Each lot shall contain a site large enough for a normal building that will meet all building setback requirements as set forth in this Code and not be subject to flood or periodic inundation.
D.
Arrangement.
Insofar as practical, side lot lines shall be at right angles to straight street lines or radial to curved street lines (including cul-de-sacs).
E.
Corner lots.
Corner lots shall be sufficiently large to permit the location of buildings so as to conform to the front building lines on both streets.
F.
Through lots.
On through lots (i.e., "double-frontage" lots) the minimum front yard setback for principal buildings shall be provided along each street.
G.
Flag lots.
Flag lots must meet the minimum lot width for the applicable zoning district at the minimum front setback line required for principal buildings.
H.
Lot remnants.
Lot remnants (lots below minimum area or width left over after subdividing tracts of land) shall be prohibited. Such remnant areas shall be added to adjacent lots, rather than remain as unusable parcels.
If any portion of a tract is reserved for future subdivision development, the minimum lot width and frontage of the reserved area may be reduced to the width required for a future street to serve such area.
A.
Such a reserved area must be labeled "Reserved for Future Development" on the final subdivision plat, and the portion of the lot where a street will be built must be labeled "Future Street."
B.
Such a reserved area will not be eligible for issuance of a building permit unless the lot meets all requirements of this UDO, including minimum lot width and frontage requirements of the applicable zoning district.
Whenever access to a subdivision is required across land in another governmental jurisdiction, the City Engineer may request assurance from the City Attorney, and/or the other jurisdiction that access is legally established, and that the access road is adequately improved. In general, lot lines shall be laid out so as to not cross jurisdictional boundary lines.
A.
The project design standards and requirements of this Article may be modified in the case of a Planned Development (PD) which, in the judgment of the Carrollton Mayor and City Council, provides adequate public spaces and improvements for the circulation, recreation, light, air and service needs of the tract when fully developed and populated, provided zoning density standards for the entire tract are not exceeded, and which also provides such covenants or other legal procedures as will assure conformity to and achievement of the plan.
B.
Plans for such developments shall be submitted to and approved by the Carrollton Mayor and City Council as a Planned Development (PD), as required by this UDO. No building permits shall be issued until such approval has been given.
By definition, a minor subdivision does not involve the construction of major public improvements, such as new streets or stormwater detention. However, the following improvements are required in order to adequately serve the lots and protect the safe operation of the existing road:
A.
Right-of way shall be dedicated along the property's frontage from the centerline of the existing road equal to ½ of the minimum requirement for the classification of the road, as established in Section 6.07.04. Minimum road improvements, (i.e. additional lane widening, curb and gutter, roadway overlay, etc.) may be required, if determined necessary by the City Engineer, to bring a substandard city road facility up to a minimum acceptable standard, within the limits of the property frontage being subdivided if the proposed subdivision is greater than five (5) lots. The requirement for such road improvements shall not alter or change the designation from Minor Subdivision.
B.
The potential location of a driveway connection serving each lot and meeting the requirements of these development regulations shall be indicated on the final subdivision plat.
C.
The stormwater carrying capacity of the road, whether in an existing ditch or gutter, shall not be compromised. If the stormwater characteristics of the existing road are inadequate to accommodate the new lots, the City Engineer may require improvement as appropriate.
D.
Survey monument markers of all lot corners shall be provided in accordance with the requirements of Section 6.04.00.
The following improvements shall be provided by the developer or at the developer's expense in every major subdivision or individual multi-family or non-residential development in accordance with the requirements and standards contained in this Article.

A.
All required improvements have been constructed or funded in a satisfactory manner and approved by the City Engineer, or
B.
The Carrollton Mayor and City Council has received in escrow 150% of the estimated cost of installation of the required improvements, and has received a copy of an executed contract for installation of the improvements between the developer and a qualified contractor. The executed contract shall call for completion of the improvements within twenty-four (24) months of approval of the final subdivision plat.
C.
The improvements funded through the escrow fund shall be limited to final pavement topping for streets, final grassing of street shoulders, landscaping, and street and parking lot striping and sidewalks.
D.
Upon completion of deferred improvements, the as-built surveys are to be updated by the developer and submitted to the City Engineer.
A.
A two (2) inch iron pipe at least twenty-four (24) inches long shall be placed at all corners of the exterior boundaries of the subdivision or development project being developed and shall be driven no less than six (6) inches above the finished grade.
B.
Existing permanent monuments that, in the professional opinion of a registered land surveyor, are of sufficiently durable construction shall be marked and maintained.
A.
All other street or lot corners shall be marked with a three-quarter (¾) inch iron pipe at least twenty-four (24) inches long and driven no less than two (2) inches above the finished grade.
B.
All such monuments shall be properly set in the ground and shall be approved by a registered land surveyor prior to the time of final plat approval.
On developments containing floodplains, flood elevation references shall be set.
Any public utility seeking to condemn or utilize an easement over or through or within the paved portion of the public right-of-way which is under the supervision and control of the City, in order to run wires, pipes, cables, maintain dams, flow backwater, or for any other uses necessary to its purpose, shall first notify the City Engineer or its designated agent of the utility's intention to so condemn or utilize, and in all cases other than condemnation said utility shall obtain a permit from the City Engineer. Utilization shall mean any manner of use of the above-described right-of-way, including but not limited to, cutting of the pavement or boring under the pavement. Such notification shall include the location and description of the right-of-way to be condemned or utilized and the purpose of the condemnation or utilization. In the event of emergency repair service involving utilization of the paved portion of the right-of-way during hours other than normal office hours, the utility shall notify the City Engineer on the next business day.
Standard specifications regulating the installation of pipes, wires, cables, poles, lines, etc., over, through or within a public right-of-way are located within the Design and Construction Standards.

(A copy of the Design and Construction Standards shall be available for public view during normal business hours at the City Engineer's office.)
As to new installation, no public utility shall install any lines, wires, pipes or poles, or otherwise utilize a public right-of-way until after obtaining prior written approval from the City Engineer respecting the proposed location of said lines, wires, pipes, etc., in accordance with these regulations. The City Engineer shall determine if the installed location and placement of any utility along a public right-of-way meets the requirements of this Section and the Design and Construction Standards (see Section 6.05.02). The City Engineer shall then issue a written approval or disapproval to the public utility regarding the installation. Any installation made by any utility in a location other than that specified in this Section shall be removed and reinstalled in the proper location entirely at the expense of the utility. Failure to reinstall at the proper location will result in the withholding of any further installation permits. Failure to conform to this Section or the permit will result in the withholding of any further installation permits.

The City Engineer is authorized to approve a variance from the requirements of Section 6.05.00, if, in his opinion, such variance is absolutely necessary under the conditions then and there existing and such variance will not create a public hazard or otherwise be detrimental to the best interest of the City and its citizens. The City Engineer shall keep a record of all variances granted under this subsection. This record shall include the name of the utility to which said variance is granted, the description and location of the variance, and the reasons for granting said variance.
Any utility shall condemn or utilize only that portion of a public right-of-way necessary for the purpose intended. It shall leave undisturbed the area surrounding the condemned or utilized right-of-way and shall replace or repair, in kind, any structures, shrubbery, driveways, embankments, ground cover, etc., which are altered or disturbed while installing pipes, wires, ditches, or otherwise using the public right-of-way, and shall re-grade the undisturbed area to its original contours.
No street cuts for crossings will be made unless specifically approved by the City Engineer after at least three attempts to bore at different locations. Patches shall be made in accordance with City standards.
Any costs or expenses incurred by the City in repairing or replacing any such structures, etc., as described in Section 6.05.06, which are not left in their original condition by the public utilities shall be chargeable to the public utility, including reasonable attorney's fees incurred in the collection of said costs or expenses.
The utility cutting the asphalt of the roadway for the installation/repair of a utility is required to notify the City Engineer, in advance, of the date and time of the roadway backfilling and repaving so that the City Engineer can schedule an inspection of this work.
Any utility that does not notify the City Engineer in advance of the date and time of the roadway backfilling and repaving shall be fined in accordance with this Code. In addition, the utility may be required by the City Engineer to core the patching, at the utility's cost, to determine its compliance with the City of Carrollton Standard Specifications. All cost or expenses incurred by the City in repairing or replacing any structure, shrubbery, driveway, embankment, ground cover or any other item which has been altered or disturbed and not left or returned to the original condition by the utility, shall be chargeable to the utility which disturbed the area or cut the City roadway. The City shall be entitled to collect reasonable attorney's fees incurred in the collection of such costs or expenses and all costs of collection.
Easements for water, sanitary sewers and drainage purposes may be combined, but must comply with all requirements of the City of Carrollton as to width and pipe separation.
Pedestrian easements not less than twenty (20) feet wide, may be required where deemed essential to provide circulation, or access to schools, playgrounds, shopping centers, transportation, and other community facilities.

Development and building permits shall not be issued unless continuous paved road access between the property and the public street system is provided by a publicly dedicated street or an approved private street.
C.
A building permit shall not be issued on any property that does not front on or have approved access to a publicly dedicated street or an approved private street.
D.
When land is subdivided into larger parcels than ordinary building lots, such parcels shall be arranged and designed so as to allow for the opening of future streets and to provide access to those areas not presently served by streets.
E.
No subdivision or development shall be designed in a way that would completely eliminate street access to adjoining parcels of land.
F.
The minimum distance between street types shall be provided as shown in Table 6.07.01 (A), or as required by the Georgia Department of Transportation if one of the streets is a state or federal route. The distance between street types is measured from the nearest right-of-way.

1.
Where an existing street on the adjoining property terminates at the boundary of the development or subdivision, the street shall be extended into the development or subdivision.
2.
Where no street exists on the adjoining property, a temporary turn-around shall be provided at the boundary of the development or subdivision at an appropriate location.
F.
Subdivisions shall be laid out so as to discourage through traffic on local streets. However, the provision for the extension and continuation of arterial and collector streets into and from adjoining areas is required.
G.
Where, in the opinion of the City Engineer or his designee, it is necessary to provide traffic calming measures to reduce the negative effects of motor vehicle use, alter driver behavior, and improve conditions for non-motorized street users, proposed developments will be required to submit traffic calming plans and/or studies to be implemented or coordinated through the approval, permitting, and construction process through the development procedures.
H.
Where a subdivision abuts or contains an existing or proposed major street, the City Engineering Department shall require marginal access streets, single tier lots, or such other treatment as will provide protection for abutting properties, reduction in the number of intersections with the major street and separation of local and through traffic.
A.
Arterial (major) Streets.

D.
Additional right-of-way.
1.
Subdivisions that include an existing street that does not conform to the minimum right-of-way requirements of this UDO shall provide additional width along one or both sides of such street or road so that the minimum right-of-way required by this UDO is established. Subdivisions abutting only one side of such a street or road shall provide a minimum of one-half of the right-of-way required by these regulations, measured from the center of the existing right-of-way.
2.
When a future street or road, as proposed in the Comprehensive Plan, adjoins or traverses the subdivision or development project, the future right-of-way shall be platted as part of the subdivision or development project. No development will be allowed within the platted future right-of-way except for drives and landscaping, and the platted future right-of-way is to be treated as a lot line for the provision of all setback lines as required by this Article. The developer will be contractually bound to the City to sell this strip of land to the City at a future date, for the amount stated in the tax digest. A right-of-way agreement shall be executed before the City Engineer approves the development.
E.
General design requirements.
a.
General design requirements for streets, including street grades, minimum design speeds, vertical and horizontal alignment, and minimum sight distance, are located within the Design and Construction Standards on file in the office of the City Engineer.
F.
Dead-end streets (cul-de-sacs).
1.
A cul-de-sac street shall be no more than 600 feet long or serve more than 19 lots, whichever is greater, unless necessitated by topographic or other conditions and approved by the City Engineer. If these conditions exist, the maximum length shall be 800 feet unless a greater length is approved by the Carrollton Mayor and City Council through the Planned Development process.
2.
Turn-around dimensions.

If any portion of a tract is reserved for future subdivision development, the minimum lot width and frontage of the reserved area may be reduced to the width required for a future street to serve such area.
A.
Such a reserved area must be labeled "Reserved for Future Development" on the final subdivision plat, and the portion of the lot where a street will be built must be labeled "Future Street."
B.
Such a reserved area will not be eligible for issuance of a building permit unless the lot meets all requirements of this UDO, including minimum lot width and frontage requirements of the applicable zoning district.
Whenever access to a subdivision is required across land in another governmental jurisdiction, the City Engineer may request assurance from the City Attorney, and/or the other jurisdiction that access is legally established, and that the access road is adequately improved. In general, lot lines shall be laid out so as to not cross jurisdictional boundary lines.
A.
The project design standards and requirements of this Article may be modified in the case of a Planned Development (PD) which, in the judgment of the Carrollton Mayor and City Council, provides adequate public spaces and improvements for the circulation, recreation, light, air and service needs of the tract when fully developed and populated, provided zoning density standards for the entire tract are not exceeded, and which also provides such covenants or other legal procedures as will assure conformity to and achievement of the plan.
B.
Plans for such developments shall be submitted to and approved by the Carrollton Mayor and City Council as a Planned Development (PD), as required by this UDO. No building permits shall be issued until such approval has been given.
