In North Las Vegas, the city's drainage study checklist bars on-site detention basins unless the Director of Public Works approves them, and the Director may approve them for development inside Apex Industrial Park. A site next to a future Clark County Regional Flood Control District facility must build drop inlets that collect all of its 100-year discharge, and any work in NDOT right-of-way needs an NDOT encroachment permit before the city approves the improvement plans. Those rules, the city's own water and sewer standards and the scale of the Apex build-out shape the surety, liability and builders risk plan for North Las Vegas work.

## Key Decision Points
- On-site detention basins are prohibited unless the Director of Public Works approves, with Apex Industrial Park named as the place approval may be given.
- Sites next to a future regional flood facility build drop inlets sized for 100 percent of the 100-year discharge.
- Off-site grading or concentrated flows onto a neighbor need a notarized letter from that owner before the drainage study is approved.
- City water and sewer work follows UDACS-2025, the 2019 wastewater standards and the city's addenda.
- The Development and Flood Control Division collects sureties and issues grading and off-site permits.

## One Division Holds the Permits and the Sureties

North Las Vegas sits inside the Clark County dust program and the Regional Flood Control District's master plan, like the rest of the valley. What differs is how the city organizes the work. Its Development and Flood Control Division reviews civil improvement plans, maps, drainage studies and water and sewer technical studies, calculates and collects development fees, agreements and sureties and issues the permits for grading and off-site construction.

The same division administers the city's FEMA flood zones and Community Rating System, implements the regional flood control master plan, coordinates the city's conformance with the Las Vegas Valley municipal storm sewer permit and runs the Southern Nevada Water Authority well conversion program inside the city. For a developer, that means the bond, the grading permit and the drainage approval move through one office, and a problem in the drainage study can hold up the surety and the permit together.

The valley-wide dust permit and regional drainage review are covered under [Las Vegas Valley dust, water and drainage rules](https://mycontractorsinsurancequote.com/nevada/metros/las-vegas).

## Drainage Study Rules That Change the Site Plan

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.

### Illustrative scenario: Logistics Building with a Future Regional Channel Along the Frontage

A developer is building an 800,000-square-foot logistics building on 50 acres in North Las Vegas, outside Apex. The 2023 regional Master Plan Update shows a future flood control facility along the frontage, so the drainage study adds drop inlets sized to collect the site's entire 100-year discharge, and on-site detention is off the table without the Director's approval. The site also drains toward an NDOT highway, so the civil engineer obtains an NDOT encroachment permit before the city approves the improvement plans, and the grading contractor needs a notarized letter from the neighboring owner for off-site grading. The broker review sizes the off-site bond to the improvement agreement, checks that builders risk includes the drop inlets and channels during construction, reads the indemnity in the neighbor letter against the grading contractor's general liability and confirms the water contractor's bond will stay in place until the city accepts the UDACS-2025 work.

## Neighbor Letters and NDOT Permits Before Plan Approval

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.

## City Water and Sewer Standards

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.

## Apex Industrial Park and Large-Footprint Projects

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.

Values, delay and equipment terms for large industrial buildings are covered under [builders risk for industrial projects](https://mycontractorsinsurancequote.com/builders-risk-insurance/industrial-and-data-center-projects).

## Tenant Pretreatment and the Owner's Pollution Picture

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.

## Before You Ask for a Quote

### What to Gather
- Drainage study with the city checklist, the 2023 Master Plan Update maps and the engineer's stamp
- Notarized neighbor permission letters for off-site grading or concentrated flows
- NDOT encroachment permit for any work or discharge in state right-of-way
- Improvement agreement, surety and grading and off-site permits from Development and Flood Control
- Water and sewer plans with the UDACS-2025 and DCSWCS-2019 editions and city addenda named
- Builders risk values for drop inlets, channels and other flood facilities during construction

### What to Ask the Insurer or Surety
- Does builders risk include earth movement, flood and unfinished drainage facilities, and at what deductibles?
- What indemnity and additional insured terms do the neighbor letters and NDOT permit require?
- Will the surety bond off-site work that includes regional master plan facilities?
- How long will the water and sewer performance bond stay open before city acceptance?
- Does each contractor's pollution coverage respond to runoff or a release during commissioning?
- Would a project-specific liability or pollution placement simplify a large Apex site?

## Broker Notes

**Quick Answer:** North Las Vegas bars on-site detention unless the Director of Public Works approves it, with Apex Industrial Park named as eligible, requires drop inlets for the full 100-year discharge next to future regional flood facilities and needs NDOT permits before plan approval.

**Common Mistake:** Designing a site around an on-site detention basin outside Apex, then redesigning late when the city's checklist rules it out, which pushes grading, bonding and builders risk dates back.

**Broker Perspective:** A broker reads the drainage study conditions, the neighbor letters and the NDOT permit with the contracts, because each one moves water risk, and the indemnity terms in them decide whose policy answers first.

**Coverage Impact:** Storm damage to unfinished drop inlets and channels may or may not be included on builders risk depending on earth movement and flood terms. Runoff onto a neighbor is typically a liability question, and the off-site surety bond protects the city, not the developer.

## Questions Buyers Ask

### Can we use an on-site detention basin in North Las Vegas?

Only with the Director of Public Works' approval. The city's drainage study checklist prohibits on-site detention basins unless the Director approves, and it says approval may be given for development inside Apex Industrial Park. Sites draining to NDOT right-of-way may still need detention to keep 100-year flows from increasing.

### What does North Las Vegas require next to a future regional flood channel?

The checklist requires the developer to build drop inlets at the site's discharge point along the future facility's alignment that collect 100 percent of the site's 100-year discharge. Where a project must build facilities shown on the regional master plan, structural drawings go to the city before the flood control district reviews them.

### Which water and sewer standards apply to new development in North Las Vegas?

The city's utility requires the Uniform Design and Construction Standards for Potable Water Systems (UDACS-2025) and the 2019 Design and Construction Standards for Wastewater Collection Systems, each with the city's addenda, plus its approved materials list and as-built requirements. Naming the editions in the subcontract helps avoid acceptance disputes.

### How large is the Apex Industrial Park build-out?

The city's Apex page describes 18,000 acres, about 5,000 developable, and 28.5 million square feet completed, under construction or planned, including 19.2 million square feet planned. It also lists a $59 million water line and an $850 million Southern Nevada Water Authority investment supporting the area.
