(A) The surface of streets (those with curb and gutter) and the parallel bar ditches of those streets without curb and gutter may be used for drainage and erosion control purposes, to the extent the use does not interfere with the safe transportation of people and vehicles.
(B) The 10-year design storm runoff shall not exceed a depth greater than.5 feet in any arterial or collector street, except at designed dip crossings, and shall flow such that one 10 foot driving lane is free of flowing or standing water. Arterial and collector streets that are in the State Highway system shall meet current New Mexico Department of Transportation (NMDOT) criteria.
(C) The product of the depth times velocity shall not exceed 6.5 at any location in any street in the event of a 10-year design storm (with velocity calculated as the average velocity measured in feet per second and depth measured at the gutter flow line in feet).
(D) The discharge of nuisance waters to public streets shall be discouraged.
(E) All land approved for development after the date of this chapter within the City of Elephant Butte shall be served by at least 1-paved access that shall be an all-weather facility during a 10-year design storm, with all channel-crossings beneath the roadway being able to pass a 10-year design storm runoff event.
