TYPICAL RURAL ONE-WAY RESIDENTIAL AND SINGLE-FAMILY
DRIVEWAY WITH MINIMUM 3′ DEEP DITCH

SCALE: 1″ = 20′

Notes:

1.

Refer to FDOT Standard Index #273 for mitered end section and sod detail also Index #515 (turnouts) for overall detail.

2.

Sod all disturbed right-of-way.

(2)

A use permit shall be obtained prior to the commencement of construction of the connection, and a final inspection shall be approved pursuant to this division prior to the final approval of any development served by the connection.

(3)

All one- and two-family residential home sites, agricultural and other undeveloped lands shall be served by driveways which meet the following standards:

a.

Number of driveway entrances. Although a single driveway will typically serve each property, the following may be permitted:

1.

One driveway may be permitted to serve an agricultural or vacant or undeveloped property. Such a driveway shall not effect location and configuration for future development uses (e.g., special exceptions, subdivisions, site plans, etc.)

2.

Two driveways for a one- and two-family existing residential lot may be permitted if all of the requirements of this section are met and if the minimum distance between the two driveways equals or exceeds 30 feet.

3.

Three driveways entering a one- and two-family existing residential lot may be permitted if all of the requirements of this section are met and if the minimum distance between adjacent driveways equals or exceeds 100 feet.

No more than three driveways will be permitted for a one- and two-family existing residential lot.

b.

Driveway location limitations.

1.

No driveway shall be constructed in the radius return of an intersection.

2.

No driveway shall be constructed with a corner clearance of less than 50 feet measured along the edge of the traveled way between the return radius and the nearest point of the driveway on or adjacent to thoroughfares. This distance may be reduced to 25 feet on local streets.

3.

No driveway entrance shall include any public facility such as traffic signal standards, catch basins, crosswalks, loading zones, utility poles, fire alarm support, meter boxes, sewer cleanouts or other similar type structures.

e.

A 25-foot paved radius or equivalent chord return are required on thoroughfares with posted speeds of 45 m.p.h. or more on 3,000 ADT.

(5)
