The regulations, restrictions and requirements of this chapter are intended to promote the general health, safety, convenience, and welfare of the residents of the City. Such regulations, restrictions, and requirements are deemed necessary to conserve and stabilize the value of property all in accordance with the powers of municipalities.
A comprehensive drainage plan will be required under the following circumstances:
Any commercial or industrial development within the municipal limits or within the City extraterritorial zoning jurisdiction.
A drainage plan shall be required for subdivisions within the City planning and platting jurisdiction for any subdivisions or resubdivisions containing four or more lots.
For a subdivision or resubdivision containing less than four lots within the City limits or within the City planning and platting jurisdiction: The City Engineer will review the proposed development and determine whether a drainage plan will be required. There shall be a flat fee of $300 charged for the Engineer's review, to be paid by developer.
The following design criteria shall be used for developing a drainage plan for areas outlined in § 212-2.
All storm drainage computations will be performed using the one-hundred-year frequency — twenty-four-hour duration storm event as defined by the NOAA Atlas 2, Volume IV for New Mexico.[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
Peak discharge and volumetric stormwater runoff values shall be estimated for predeveloped as well as post-developed site conditions.
Peak discharge and volumetric stormwater runoff values shall be estimated for all off-site areas which may impact the site.
All stormwater runoff shall be estimated using methodology which is considered a standard of practice in the engineering field and deemed as such by the City Engineer.
The plan shall include a scheme for controlling the increased runoff from pre-developed to post-developed conditions. The increased runoff must be controlled on site. Stormwater runoff which is allowed to discharge from the site must leave the site at the existing flow path or discharge point on the site. In no instance shall stormwater runoff be released from a site which may adversely impact the downstream capacity of any drainage structure by either peak rate of flow or volume.
All plans shall include a copy of the appropriate FEMA (Flood Insurance Rate Map) panel on the plan to indicate that the site does not lie within a designated one-hundred-year floodplain. All improvements shall be constructed so as not to be built within a designated one-hundred-year floodplain. Any revisions to the floodplain maps shall be the responsibility of the developer.
All roads shall have a minimum width of 12 feet free from flowing stormwater runoff during the one-hundred-year storm event for emergency vehicle access.
The plans shall be Mylar reproducible with India ink either 18 inches by 24 inches or 24 inches by 36 inches depending on the scope of the project.
All plans will be based on the Albuquerque DPM Design Standards or other methods approved by the City of Las Vegas. Such approval shall be obtained by the developer prior to submittal.
The fee for the drainage plans shall be $300 for up to the first five acres of land within the project, plus $10 per acre for each to be paid at the time the drainage plan is submitted for review by the City Engineer.
Commercial and industrial. The drainage plan shall be submitted at the time a building permit is requested. No building permit shall be issued until the drainage plan has been approved by the City Engineer.
Subdivisions/resubdivision. The drainage plans shall be submitted along with other materials submitted for preliminary plat approval. No preliminary plat approval shall be granted until the drainage plan has been approved by the City Engineer.
A finished drainage product shall be certified as record drawings by a registered professional engineer before final acceptance by the City.
It shall be the sole responsibility of the developer to properly maintain all drainage facilities constructed. This includes, but is not limited to, drainage ponds, storm sewers, manholes and drop inlets.
