Driveway and Commercial Access Connection Drainage Requirements. Three conditions of roadside drainage, not including curb and gutter, govern the construction of any structure in the drainage swale.

A.

Condition A.

1.

Condition A consists of drainage swales of 0.7 feet or less below the edge of road pavement, or swales or ditches designed to provide driveway access without culvert pipe.

2.

No pipe, either driveway or continuous swale pipe, is permitted under Condition A. Driveways shall be paved following the slope of the designed swale grade.

B.

Condition B.

1.

Condition B consists of drainage swales beginning 0.7 feet below the edge of the road to the following:

(a)

For residential driveways, depth equal to 0.70 feet plus pipe diameter and the top wall thickness (i.e. 2.15 feet for 15-inch RCP).

(b)

For commercial accessways, depth equal to one foot plus the pipe diameter and the top wall thickness (i.e. 2.45 feet for 15-inch RCP).

2.

Property owners may install a properly sized pipe in the swale for driveway purposes providing they meet the conditions of subsections (1) and (2) in the section of specifications of structures.

C.

Condition C.

1.

Condition C:

(a)

For residential driveways, depth equal to 0.70 feet plus the pipe diameter and the top wall thickness.

(b)

For commercial accessways, depth equal to one foot plus the pipe diameter and the top wall thickness and to any depth greater than the above.

2.

The owner may install either properly sized driveway pipe or continuous pipe across the property. If continuous property pipe is proposed, one or more standard catch basins with grates will be required as dictated by the specific conditions of the area.

16.

Drainage. The following standards for drainage shall apply:

A.

Curb and gutter type B, F and drop or shoulder (valley). See FDOT Design Standards, current edition.

Roadside swales may be used in excessively drained and somewhat excessively drained to moderately well-drained soils, except where closed drainage is required by the Director. See subsection 15, Driveway and Commercial Access Connection Drainage Requirements, 15.

C.

Roadside swales within privately maintained road rights-of-way shall have slopes no steeper than three horizontal to one vertical. Roadside swales within Village-maintained road rights-of-way shall have side slopes no steeper than four horizontal to one vertical. Normal swale sections shall be a minimum of 12 inches deep.

A deviation may be requested from the requirements of this, from the Director, in accordance with Sec. 2-506.C.2, Administrative Deviation.

E.

Underdrains

1.

Underdrains may be required on both sides of roads if, in the opinion of the Director, soils data indicates that underdrains would be necessary. In cases where there is a prevalence of soils that exhibit adverse water table characteristics, underdrains or fill or some other acceptable alternative that will provide necessary measures to maintain the structural integrity of the road shall be required. The determination of need shall be made by reference to the applicable portions of the most recent edition of the Soil Survey for Lee County, Florida, as prepared by the U.S. Department of Agriculture, Soil Conservation Service, or according to information generated by the developer's engineer. Wherever road construction or lot development is planned in areas having soil types with unacceptable water table characteristics, underdrains or fill shall be provided and shown on the engineering plans. Underdrains shall be designed with outlets at carefully selected discharge points. Erosion control measures shall be provided as needed at all discharge points. See Appendix D: Illustrations and Cross-Sections, Section F, for suggested underdrain details.

2.

Wherever road cuts in otherwise suitable soils indicate that the finish grade will result in a road surface to water table relationship that adversely exceeds the degree of limitation stated above, underdrains or another acceptable alternative that will provide necessary measures to maintain the structural integrity of the road shall be required.

C.

Minimum Specifications for Bridge Improvements. All bridge improvements shall meet the standards in the Administrative Manual.

D.

Additional Requirements.

1.

Dedication of Right-of-Way and Completion of Improvements. Prior to acceptance of the roads or the release of security, the developer shall dedicate the rights-of-way and complete the improvements, or provide funds for the completion or installation of the improvements in accordance with the standards and specifications of this section.

2.

Work in Village Right-of-Way.

A.

Except for emergency repair work, no person shall commence any work in Village-maintained rights-of-way or easements without first having obtained a right-of-way permit from the Village. For the purposes of this subsection only, "work" means:

1.

Excavation, grading, or filling activity of any kind, except the placement of sod on existing grade; or

2.

Construction activity of any kind except the placement of a mail or newspaper delivery box.

B.

The Village shall not issue a right-of-way permit for any private road to connect to any Village-maintained road other than a residential driveway, without approval of drainage plans using approved utility piping materials, in accordance with Appendix E: Piping Materials, that are prepared by a registered engineer.

C.

For single residential buildings of two dwelling units or less on Village-maintained roads, the Village will do all necessary field survey work to establish the proper grade, pipe diameter, and length for driveway culverts.

D.

The inside edge of the pavement at the driveway connection to the road shall be rounded with a minimum radius as shown in Table C-(D)2: Minimum Edge of Pavement Radius at Driveways. A deviation from these standards may be approved by the Director in accordance with Sec. 2-506.C.2, Administrative Deviation.
