A. Generally: All proposed development shall be connected to a public water system providing adequate supplies for normal usage and emergency needs. The guidelines in table 9-9:1 of this section shall be used to evaluate compliance with this provision. The zoning official and/or staff review committee may recommend and the city council may approve subdivisions which do not comply with the guidelines in table 9-9:1 of this section, subject to the following conditions:
1. The water supplier has reviewed the proposed development and stated in writing that it has budgeted improvements to provide water supplies consistent with the guidelines in table 9-9:1 of this section within two (2) years or that there is no feasible way to meet the water supply guidelines within five (5) years;
2. The fire department has reviewed the proposed development and has recommended alternative strategies for delivering fire protection services to the proposed development; and
3. The city council finds that the proposed development:
a. Will be adequately served for normal water demands;
b. Will not reduce system water pressures or supplies so as to create a hazard to the public health or safety within other development served by the water system;
c. Will not pose a threat to life or property within or adjacent to the proposed development due to inadequate fire protection; and
d. Will not impede the logical extension of services to serve growth in the city in accordance with the master plan.
B. Design Standards: All water supply systems shall be designed and constructed to meet APWA and AWWA standards or other standard adopted by the water supplier, including the VVWD and Mesquite uniform standards. Written authorization from the water supplier shall be required prior to approval of any system which does not meet these standards.
C. Off Site Improvements: The developer of a parcel shall provide for on site and off site improvements required to adequately serve a proposed development; provided, however, that the zoning official may authorize development to proceed if the director of public works certifies that the necessary capital improvements have been funded for construction within eighteen (18) months. In no event shall a certificate of occupancy be granted prior to connection to an adequate public water supply.

Improvement | ||
Minimum diameter line size (inches) | 8 | |
Minimum distance from approved emergency water supply to structure (feet) | 400 | |
Fire flow (gallons per minute) | Building separation >100' | 500 |
Building separation 31' - 100' | 750 | |
Building separation 11' - 31' | 1,000 | |
Building separation <11' | 1 | |
Notes: 1. Or otherwise as determined by the Mesquite fire code. 2. Fire flow for buildings closer than 11 feet should comply with applicable fire safety codes. | ||
D. Extension/Oversizing: Upon recommendation of the Virgin Valley water district, the public works director, the planning commission or the city council may require that water lines be oversized to accommodate future development. The city or Virgin Valley water district shall arrange to reimburse the developer for the cost in excess of the minimum line size required to serve the proposed development; provided, that no reimbursement shall be granted for installation of a water main with less than or equal to a ten inch (10") diameter.
E. Water System Construction: The zoning official shall have public works review and approve all proposed public water system improvements prior to construction and shall require inspection during construction of such improvements and final approval prior to issuance of an occupancy permit.
F. Water System Easements: The property owner shall dedicate adequate easements to accommodate all water system facilities required to serve new development, except individual service lines. The director of public works, in consultation with the Virgin Valley water district, shall ensure the location and dimensions of required easements are properly identified on the plan, but in no instance shall an easement be narrower than ten feet (10') in width. Easements should follow property lines to the greatest extent possible. (Ord. 172, 9-24-1996, eff. 10-31-1996)
