North Las Vegas Construction Insurance for Drainage, Utilities and Apex Industrial Park

The city's drainage study checklist, revised June 26, 2025, sits on top of the Regional Flood Control District's Hydrologic Criteria and Drainage Design Manual and the regional uniform standard drawings. It requires the district's 2023 Master Plan Update for all new submittals, with the flood control facilities and facility inventory maps included, and it must be signed and stamped by the engineer in responsible charge. Incomplete submittals are not accepted.

Three rules stand out. On-site detention basins are prohibited unless the Director of Public Works approves, and the checklist says approval may be given inside Apex Industrial Park. A site next to a future regional flood control facility must build drop inlets at its discharge point that collect 100 percent of its 100-year discharge. And where a project must build facilities shown on the district's master plan, structural drawings go to the city for approval before the district is asked for concurrence.

Each rule moves money into the site work line and raises the stakes of a storm during construction. A drop inlet or master plan facility that is half built when a monsoon cell arrives is a builders risk question, and water that leaves the site is a liability one.

The checklist requires a notarized permission letter from the adjacent owner before the drainage study is approved if off-site grading is planned, and another if the site will concentrate storm or nuisance flows onto the neighbor's property. Where right-of-way does not exist, a roadway or drainage easement must be obtained from the neighbor and processed through the city's Real Property Services Division before improvement plans are approved.

Projects that build in or discharge into NDOT right-of-way need an NDOT encroachment permit before the city approves the improvement plans, and the checklist notes that NDOT does not allow development to increase the 100-year flow rate into its right-of-way, so on-site detention may be required there. Those permission letters and permits are contract documents in all but name. They define what the contractor may do on someone else's land, and the indemnity and additional insured terms in them should be read against the contractor's general liability before grading starts.

North Las Vegas runs its own water and wastewater utility. New development must follow the Uniform Design and Construction Standards for Potable Water Systems (UDACS-2025) and the Design and Construction Standards for Wastewater Collection Systems (DCSWCS-2019), each with the city's own addenda, along with an approved materials list and as-built requirements. Title 13 of the municipal code sets the utility's authority.

For a water and sewer contractor, the addenda and the approved materials list are where claims start. A substitution that is not on the list, or as-builts that miss the city's requirements, can delay acceptance and stretch the time the contractor's performance bond and completed-operations exposure stay open. The subcontract should name the edition of each standard that applies.

The city describes Apex Industrial Park as 18,000 acres, about 5,000 of them developable, with 28.5 million square feet of industrial space completed, under construction or planned: 5.5 million completed, 3.8 million under construction and 19.2 million planned. Its page lists a $59 million public-private water line, an $850 million Southern Nevada Water Authority investment and NV Energy plans to add five substations to the two that exist.

Projects at that scale combine mass grading, long utility extensions and high-value buildings and equipment. Builders risk values, delay coverage tied to utility completion and the contractor's pollution coverage for site work all deserve attention early, and Apex is the one place in the city where the checklist contemplates approving on-site detention, which changes what is being built and insured.

The city's industrial wastewater pretreatment program requires facilities with chemicals on site to complete an environmental and wastewater survey and lists prohibited discharges, including fuels, solvents, acids, bases and heavy metals. City inspectors issue permits and schedule inspections and sampling.

That is mainly an operating issue for tenants, but it reaches the construction program when an owner builds pretreatment systems, interceptors or chemical storage into the shell. A project-specific pollution policy, or careful review of each contractor's pollution coverage, can address a release during construction or commissioning that the general liability pollution exclusion might leave open.
