§ 7. Public use and service areas.

a.

Storm drainage.

(1)

Major drainage course. Whenever any stream or major surface drainage course is located in an area that is being subdivided, the subdivider shall dedicate an adequate right of way along each side of the stream for the purpose of widening, deepening, sloping, improving or protecting the stream or for drainage maintenance. Such right of way shall have a total width equal to the bottom width of the drainage course plus 24 feet plus four times the total depth of the drainage course, as given by the formula:

ROW = W + 24′ + (4d)

Where W equals the designed bottom width, d equals the total designed depth and ROW equals the total right of way width (in feet), and a width of not less than eighteen (18) feet shall be maintained on one side of the drainage course for purposes of equipment access for drainage course maintenance. Such streams and major surface drainage courses referred to above include Dumpling Creek and its two major branches north of Highway 190, Middle Colyell Creek and its branches located in the western portion of Walker and in the eastern portion of Walker known as Corbin, all as shown on the U.S. Geological Survey quadrangle may at scale 1:24,000 dated 1962 (AMS 7844 IV NE-Series V885), and other similar major drainage courses so designated by the Town Council.

Whenever such stream or major surface drainage course is located along the boundary of an area that is being subdivided, the subdivider shall dedicate one-half (½) of such right of way plus six (6) feet.

(2)

Major laterals. Whenever any major lateral drainage channel draining into a major drainage course as described in (1) above, is located in an area that is being subdivided, the subdivider shall dedicate an adequate right of way along each side of the lateral channel for purposes similar to those stated in (1) above. Such right of way width equal to the bottom width of the lateral plus eight (8) feet plus four (4) times the total depth of the lateral as given by the formula:

ROW = W + 8′ + (4d)

Where W is the designated bottom width, d equals the total designed depth and ROW is the total right of way width (in feet) and a width of not less than six (6) feet shall be maintained on one side of the channel for purposes of equipment access for channel maintenance.

(3)

[Minimum grade.] The minimum grade along the bottom of any surface drainage course shall be a slope of 0.125 per cent (or a vertical fall of one (1) feet in each eight hundred (800) feet or horizontal length).

b.

Easements for utilities. Except where alleys are provided for the purpose, the Town Council will require a servitude of not less than 5 feet in width on each side of all rear lot lines for poles, wires, and/or where feasible, for sanitary sewers, gas, water or other utility lines unless it is not feasible in opinion of the Town Council. Wherever it is necessary to install sanitary or storm sewer or drainage ditches along side lot lines or across lots, a sufficient servitude shall be required to contain the necessary services as determined by the Town Council.
