Show arrows on drainage easements to indicate direction of flow. Open drainage ditches must have 4:1 side slopes or flatter. The entire drainage ditch must be within an easement. Between residential lots, storm sewer drainage pipe 4 UPDATED AS OF 6/5/2007

must go at least to the rear of the property line, 140 feet from the street, or to the flood plain limits. The pipe should end a minimum distance of six times the diameter of the pipe, to allow for the storm drain outlet protection. If a proposed street intersects an existing roadway with a ditch, provide a drainage system for the existing ditch flow.

Roadway Considerations Driveways on County Roadways Each driveway providing access to a public roadway is to be constructed according to Georgia D.O.T. Standard A2 (which replaced 9031J) (concrete apron) or Clayton County Standard No. 205 unless heavy duty paving is provided. Provide the detail on the plans. The width and radii of each driveway are to meet the requirements of Standard No. 205 in the Land Development Guidelines. The profile should provide a high-point (or low point) to prevent runoff from flowing out the driveway onto the street. Indicate the distance from each driveway to the nearest public road intersection. Sidewalks may be required as described in the County Guidelines and Ordinances. If sidewalk is required, provide a standard detail of the sidewalk and clearly indicate its location. Refer to County Standards located in Appendix D of these Guidelines. Indicate the right-of-way of all public roads bordering this property. Clearly indicate the width of the existing roadway (indicate whether this dimension includes the curb and gutter if applicable). Show the angle of the driveway from the existing roadway if other than 90°. Further review by this department may be necessary depending on the severity of the angle. Provide an enlarged detail of the curbing to be used within the right-of-way of the County road. Flared end sections may be required as the end treatment on driveway pipe in lieu of headwalls to meet traffic safety requirements. If the driveway accesses Georgia D.O.T. rights-of-way, a driveway permit must be applied for through the Georgia D.O.T.

Acceleration/deceleration lanes If a widened section is required, provide a typical section that indicates the following: asphalt and base thickness and type, Please refer to Table 2. Basic Standards for Undivided 2 and 3 Lane Subdivision Streets of the County Guidelines shoulder width 5

type of curb and gutter (indicate dimensions) total right-of-way width compaction requirement maximum and minimum shoulder slopes and crown to match the existing cross slope of the roadway

A flume may be required at the end of a widened section to control runoff. If so, indicate size and location. On the Plan Sheet, clearly indicate the length of the acceleration/deceleration lane, the length of tapers, and the location of curb and gutter. Provide a standard detail for the curb and gutter.

Subdivision Development - Roadway Construction Indicate the radii of curbs at intersections - 25 foot minimum for interior streets in a subdivision, 35 foot minimum for an intersection with an existing county roadway provide a standard detail. Provide a typical section of the proposed road showing the asphalt and base thickness, paving widths, shoulder widths, total right-of-way widths, compaction requirements, base and asphalt type, maximum and minimum shoulder slopes and road crown - standard detail is available from this department. If underground power is proposed, provide stub-outs for future street lighting based on an approved street lighting plan. Show an enlarged detail of the curbing to be used - standard detail. Show the cul-de-sac and right-of-way dimensions and the location of the center of the radius. Horizontal and vertical curves shall have the curve data provided. The minimum radii of a horizontal curve is 200 feet. The maximum grade is 12% and minimum grade is 1.5%. The minimum length of vertical curves is 10 X the algebraic difference in grades. Provide a profile of all roads at a scale of 1" = 10' vertical and 1" = 50' horizontal. Show all tangent slopes and vertical curve lengths. Acceleration and deceleration lanes may be required. Five foot wide minimum sidewalks are to be installed on both sides of interior streets and next to County roadways, provide a location plan. If not, note on the typical section that it is to be excluded. Add a note to the plans that all areas used as burial pits during development must be located outside the right-of-way and are to be located and identified on the final plat. Georgia DNR EPD requirements are to be met: "no portion of waste disposal area shall be located within one hundred (100) linear feet of any property line or enclosed structure." This means that home builders will not be able to place an inert waste landfill on most lots smaller than one-and-one-half acres. Indicate the locations and types of street signs to be installed - custom signs or MUTCD signage purchased from Clayton County.

A final inspection will be made based on the approved plans. All changes to the approved plans must be made in writing so that these changes may be reviewed before approval. SEDIMENT CONTROL
