Drainage Review/Submittal

When is a drainage study required?
If the site is impacted by a FEMA designated Special Flood Hazard Area, adjacent to or impacted by a Master plan Facility, or is impacted by flows from a wash or facility then a drainage study is required. A determination is made for each site based on the proposed development, size of development, and location in relation to other factors.

Drainage Review Group - reviews drainage studies and grading plans for conformance to code requirements and drainage regulations. Coordinates with Clark County Regional Flood Control District on flood plain issues.

Kent Chang, P.E. Associate Engineer 702-455-6115

This group is responsible for reviewing and approving traffic impact analysis relating to private development projects. It may be required by the County in order to adequately assess the impact of a proposed development on the existing and/or planned street system. This section performs a variety of functions including:

  • Comprehensive Traffic Study
  • Traffic Mitigation Letter
  • Queuing Analysis
  • Pedestrian Pathway Analysis
  • 3 Point Turning Analysis
  • Multi-Way Stop Control Warrant Analysis
  • Traffic Signal Warrant Analysis 

What determine if a traffic study is required for a development project?
Traffic impact analyses may be required for the following submittals:
  1. For a rezoning application. 
  2. For a tentative subdivision map, if the property has been previously zoned for the proposed use and no traffic impact analysis was required at the time of zoning. 
  3. Prior to issuance of a building permit, if the property has already been zoned or subdivided and no previous traffic impact analysis less than one (1) year old exists. 
  4. The applicant may be required to submit a new traffic impact analysis if, after submitting the original analysis, the land use intensity or traffic generation are increased.
Where access points are not defined or a site plan is not available at the time the traffic impact analysis is prepared, additional traffic analysis may be required when a site plan becomes available or the access points are defined.

Who prepares traffic studies for development projects?
When required, a traffic impact analysis shall be the responsibility of the applicant and must be prepared and sealed by a Nevada Registered Professional Engineer with appropriate experience in traffic engineering. Upon submission of a traffic impact analysis, County staff will review the assumptions, procedures, sources, methods, findings, and will provide comments in written form. The developer and his engineer will then have an opportunity to submit an addendum to incorporate any necessary revisions.


Structural (If required)
Public Works Structural Reviews

Public Works structural submittals are generally required by the Drainage Study Approval letter for structures located within a public or private drainage easement. All plans and calculations need to be stamped, signed and dated.

Structural calculations and construction plans are required for items such as: Cast-in-place RCB’s or arches, custom drop inlets, transition structures, retaining walls, channels, headwalls, wall openings, collar connections & gabion baskets.

Note: Wall footing need to be within the easement if wall is. If wall is outside the easement, footing must be too. Structural review is not required for pre-cast items, but details must be added to the plan set for precast drop inlets, NDOT details or specialty items. Foundations for Cell sites located in the public right-of-way are also reviewed.

Note: Offsite Improvement plans are not accepted until the structural review is approved.

Research on past structural reviews can be accessed through “Document Image Search” under application type Drainage Studies and your record number (No PW).

Tracking for current reviews can be done through “Citizen Access Link” using your record PW number.  

Submittal requirements:
Structural submittals are accepted after the approval of the drainage study or as needed for cell sites.

The fee is $750 (Covers 1st & 2nd Review). Subsequent reviews are $400. Additional fees will be assessed in $750 increments for multiple types of structures (as determined by the reviewer during first review).

Drainage related submittals should include:

  • Submittal sheet 
  • 1 copy of Geotechnical Report (Stamped and Signed / Provide update letter if report is over 1 year old.)
  • 1 set of Civil Plans (Cover, Grading, Details and Plan & Profile Sheets - Stamped, Signed and Dated)
  • 2 sets of Structural sheets (Stamped, Signed and Dated)
  • 2 sets of Structural Calculations (Stamped, Signed and Dated)
  • Drainage study approval letter and copy of APPLANS
  • Previous redlines to be included with a subsequent submittal
Cell foundation submittals should include:
  • Submittal sheet
  • SLA (Site License Application) for sites.
  • Letter of Explanation - explaining if it is a new site, new pole, new foundation or what is existing. Single site? 
  • 2 sets of calculations for the foundation using unrestrained conditions and listing the pole, proposed equipment with elevations and weights. (Stamped, Signed and Dated)
  • 2 sets of plans including full construction drawings for the foundation, anchor bolts, base plate including concrete strength of 4500 psi and type V cement. (Stamped, Signed and Dated) Plans showing the pole (Indicating type and manufacturer) with callouts for the equipment and heights and base plate. (Stamped, Signed and Dated)
  • Title sheet listing location of site Carrier ID# and SLA #, sheet index, scope of work, contacts, notes etc. If multiple sites; provide a chart with SLA number, Carrier ID number, Location ( N side Flamingo 200’ E of Paradise) and what option if there are options.
The following notes should be somewhere on the foundation sheets:
1. Structural design acceptance is valid only for pole foundations installed on leveled surfaces. Any foundation installed within (5ft) from a slope will require slope stability analysis and calculations with a separate structural review and fee. A geotechnical report will be needed for the review. 
2. Sidewalks must be unobstructed and have an access of at least 4.0-ft from back of curb.
3. NEC Code to be followed.
4. Work to comply with Clark County Standard Specifications Drawings # 313, 316, 320, 320.1, 321 and any other applicable standard drawings. Standards can be found at
Inspections shall be performed by an ICC certified inspector approved by Clark County; and employed by the owner/developer.

Provide special inspections in accordance with the 2018 International Building Code and CC Standard Spec 623 for the items listed below.

    • Concrete Strength- Continuous
    • Welding
    • Concrete Placement-Continuous
    • Galvanizing
    • Grout-Continuous
    • Pole modification
    • Reinforcing Steel Placement- Periodic
    • Brackets
    • Equipment Installation 
5. The inspector shall submit a statement to the Owner/developer, Structural Engineer and Clark County Inspections indicating compliance with the plans and specifications.

6. Inspection of the fill around the ((street light foundation...) shall be provided at a frequency as necessary to ensure that proper fill and compaction is achieved. Compaction test for each lift shall be taken per CCAUSD 203.05.02.
On-site or  Early Grading (option)

Where grading will occur on a privately owned parcel, a building permit is required.  As part of the permit review process, plans are routed to Public Works Development Review.  Some projects require a drainage study, traffic study and/or off-site permit.  For those projects that do not require additional studies or have construction proposed in the right of way, review of the plans submitted to the Building Department will only be part of the Civil step.

As of January 2, 2019, the revised Early Grading process went into effect at the Building Department. This process was developed as a result of the 2018 Ad-Hoc Committee.  The primary changes are that Zoning Plans Check will not be a part of the review process.   The plans are approved for "Grading Only" and may be used as the Public Works approval of the grading permit.

Public Works has always had an Early Grading submittal process.  To our department that just means that it is a "grading only" approval prior to off-site permit issuance.  Under the newer process the $5 million insurance policy has been replaced with a per acre deposit. The Grading Agreement has been revised accordingly.  It is anticipated that this new process will significantly reduce the duration to issue an Early Grading Permit. The deposit will be returned upon request after the issuance of the required Off-Site Permit.

See On-site Submittal Options, Grading Submittal Form and Grading Agreement.  Projects that do not require construction of off-site improvements do not require the Grading Agreement or deposit.
Offsite Improvement Permits
Offsites – Improvement Plans Review

The offsites team under the Development Review Division is responsible for providing professional and technical services specifically related to the review of improvement plans from developers in public right-of-way and easements. The offsites team issues permits for approved plans and manages revisions of approved plans. A typical offsite review includes verification of land use conditions, final maps, easements, pavement design and compliance with drainage, structural, traffic, design division, inter-agency concurrence, utility companies and BLM criteria.

Note: Once permit has been issued, refer to Construction Management tab for traffic control permits, inspections and bond release information.
