§ 14-376. Standards.

(a)

Generally. Street improvements shall be provided in each subdivision in accordance with the specifications in this part and the standard plans and specifications available from the county. The term "state transportation department specifications'" shall refer to the state department of transportation specifications in effect at the time the work is placed under contract. The references made to these specifications shall control the materials and equipment as well as the construction method of every class of work so applicable unless otherwise noted.

(b)

Grading. The construction limits shall be cleared of all trees, stumps, brush and rubbish before grading operations are begun. No trees, stumps, brush or rubbish shall be placed in fill sections within the construction limits. Such debris shall be disposed of in a manner satisfactory to the development director. Fill sections shall be placed in six-inch layers with each layer thoroughly compacted with a sheep foot roller or by other approved methods before the next layer is placed, compaction to be not less than ninety-five (95) percent as determined by AASHO, section T-99. Where unsatisfactory material is encountered (namely any material that will not compact properly, including solid rock) an additional twelve (12) inches shall be excavated below the subgrade elevation and backfilled with a select material. Where unstable material is used in fills, the fill shall be left twelve (12) inches below the subgrade elevation. This twelve-inch fill section shall be filled with select material. Streets shall be graded to width of not less than forty-two (42) feet in the center of the right-of-way to provide eight-foot shoulders in accordance with county's standard plan.

(c)

Curbing. Header curbing shall be required on all streets and shall be furnished and installed by the applicant unless grassed swales are used for water quality control and approved by the development director. The minimum classes and types of curbing permitted will be as follows:

(1)

Granite curbing, class D or better.

(2)

Other as approved by the development director. All curbing shall be placed in firm well-compacted subgrade, and curbing displaced prior to acceptance for maintenance by the county shall be reset or replaced. Specifications for the granite curbing are available from the DeKalb County Development Department.

(d)

Base and paving. All roadways shall be paved according to the specifications prepared and approved by the development director in effect at the time a development permit application is received by the development department.

(e)

As-built drawings for all new streets shall be submitted to the development department depicting a street profile based on the centerline and fifty (50) foot stations.
