Environmental Oversight

20170730-Lightning-04.jpg

Providing multiple services including air quality management, endangered species act compliance, multiple species habitat conservation planning, groundwater discharge permitting and multiple species habitat conservation planning. In addition we provide hazardous waste coordination, marijuana establishment environmental oversight, national environmental policy act compliance, water conservation and Stormwater quality management.

The Stormwater Quality Management Committee is a community partnership of the Clark County Regional Flood Control District and is committed to the development and implementation of stormwater pollution monitoring, control and outreach efforts. The committee manages programs and compliance activities under National Pollutant Discharge Elimination System Municipal Separate Storm Sewer System permit.

The permit authorizes discharge of storm water to the Las Vegas Wash from storm sewer systems owned and operated by the cities of Las Vegas, North Las Vegas, Henderson and Clark County in return for implementation of certain storm water pollution reducing activities by the permittees. Visit the Stormwater Quality Management Committee webpage to learn more. For environmental questions or concerns within the city of Las Vegas, call our Environmental Oversight office at 702-229-7318.

Special Improvement Districts

Special Improvement Districts

Improvement Districts are created to fund public improvements such as roads, curbs, sidewalks, utilities, etc. Usually, these public improvements are funded from the proceeds of a bond issue sold by the municipality. Bonds for your district were sold after a majority of the district's property owners agreed to the district. All properties benefiting from these improvements are included in the district. For more information or to make payments for special improvement districts, please visit this website

Subdivision Mapping

Subdivision Mapping

The city of Las Vegas Survey Section reviews and approves subdivision maps, parcel maps, reversionary maps, boundary line adjustments and certificates of amendment for technical correctness and conformance to all applicable local, state and federal statutes. 

Design Services

Design Services

Provide oversight for the design and architecture of city facilities and infrastructure including roadways, bridges, bus stops, intersection improvements, bike lanes, sidewalks, median landscaping, flood control, sanitary sewer, trails, recreation centers, fire stations, parks, parking garages and more. View design-related resources.
Horizontal Control Network

Horizontal Control Network

The city is currently building a network of horizontal control stations for use on engineering and construction projects, and general surveying. The network is aligned to the current NGS geodetic datum and is compatible with the State Plane Coordinate System, Nevada East Zone and the Nevada Coordinate Reference System (NCRS). The backbone of this network is the Las Vegas Valley Water District (LVVWD) GPS base station network.  When LVVWD broadcast coordinates are combined with an NCRS coordinate system, alignment to the city’s horizontal control network is virtually automatic. All elevations to be used on surveys within the city should be referenced to system of benchmarks that comprise the city’s vertical control network. Below are some coordinates on existing Clark County GIS control points, LVVWD base stations for reference and some coordinates for natural control on prominent structures.
Construction Management

Construction Management

Provide oversight of the city’s active construction projects and compliance with safety, environmental, costs, contract and design standards.

Guidance documents include, but are not limited to, the following:

Vertical Control Network

Vertical Control Network

The city maintains a network of of approximately 2,500 benchmarks for use on all engineering and construction projects aligned to the current NGS vertical datum, NAVD88. Periodically the network has been adjusted to account for subsidence due to seismic activity and groundwater extraction. Currently the city publishes benchmark elevations based on the most recent adjustment published in 2008. City benchmark elevation references should indicate the published adjustment (e.g., 1234.56’ NAVD88 2008 Adjustment). The vertical control network undergoes continuous maintenance as benchmarks are destroyed and replaced.
Nevada Coordinate Reference System

Nevada Coordinate Reference System

The Nevada Coordinate Reference System (NCRS) works seamlessly with GPS and published RTK networks, and it is ready-made to integrate with GIS and other georeferenced data. The NCRS zones were designed to be as large as possible without sacrificing accuracy. They can be used in their original form (not scaled) and still be accurate enough to meet the needs of the surveying and engineering community.  Please read the overview of this system and than utilize the resources below.

Surveying for Capital Improvement Projects

Surveying for Capital Improvement Projects

City of Las Vegas capital improvement projects (CIP) refer to all projects that are publicly funded and managed by the city. These include public works projects for roadway, sewer, storm drain and city-owned facilities such as parks, community centers and fire stations. The surveying for these projects are provided by consultants, contractors and city staff. All surveys for these projects are to follow city-specific standards.
Surveys prepared for engineering design include topographic mapping, as well as roadway alignment, right-of-way and boundary surveys. Most projects will require a record-of-survey prepared to memorialize any alignments, rights-of-way, boundaries and survey control the project scope requires.  All topographic surveys that utilize aerial mapping require both verification and supplemental field surveys to be performed. Any projects that require design of any surface grading or drainage will require an existing ground DTM to be prepared. This DTM shall incorporate the best available survey information from all location methods performed; be it aerial mapping, lidar scanning, conventional surveys, etc. This DTM is to be approved by the project’s surveyor of record and submitted to the City Surveyor for approval prior to beginning any surface grading design. All CAD drawings prepared by the surveying consultant shall adhere to city CAD standards.  See the Standard CIP Design Survey Scope and Requirements
Construction surveying required for city capital improvement projects include construction layout/staking, utility final location surveys (open-trench as-built surveys) and post-construction monumentation surveys. All construction staking shall comply with state-mandated accuracies per NAC 625.775 .  Be advised, the city does not believe a vertical positional certainty of 0.05 feet (or better) can be achieved through GPS measurements alone, and proper consideration should be given to the equipment used for stakes requiring that level of accuracy.
Private Development Projects

Private Development Projects

Private development projects refer to all civil improvement projects administered by the Department of Building & Safety’s Land Development and Offsite Inspection division. Survey’s for these projects include engineering design for civil improvement plans, construction staking and utility final location. 
All civil improvement plans shall be based on a land survey performed by a professional land surveyor registered in Nevada. These surveys should be referenced to a valid city survey benchmark  located within close proximity to the project, as well as sufficient survey monumentation to control the boundary of the project property. The benchmark and survey monument information is to be included within the civil improvement plans.
All construction staking for private development projects shall comply with NAC 625.775. Be advised the city does not believe a vertical positional certainty of 0.05 feet (or better) can be achieved through GPS measurements alone, and proper consideration should be given to the equipment used for stakes requiring that level of accuracy.
Per NRS 455.131  all installed underground sanitary sewer and storm drain facilities within a public right-of-way or public utility easement shall either be located by the developer’s surveyor or the city. Any hardcopy submittals should be submitted to 416 N. 7th St.
The city inspects, reviews and approves Monumentation Tie Maps submitted by private sector surveyors to insure compliance with: NRS 278.371 - Survey, setting of monuments and preparation of final map; NRS 625.380 - Requirements for monuments; UDC Appendix D - Monumentation Requirements; and the Uniform Standard Drawings – Clark County Area. In cases where monumentation is called for which is not associated with a recorded map, such as Capital Improvement Projects (CIP), a Record-of-Survey must be filed to comply with NRS 626.340. These Records-of-Survey must be reviewed and approved by the City Surveyor prior to recording and before final release of the project can occur.
Flood Control

Flood Control

Flood Control

The purpose of the Flood Control Program is to provide regional and neighborhood planning, drainage study review, and Federal Emergency Management Agency (FEMA) flood plain management services to developers, citizens, city departments and other public agencies so they can construct drainage infrastructure and elevate structures to reduce the risk of flooding impacts.

Flood Insurance Information

Drainage Studies

We review and approve technical drainage studies addressing the existing, interim and future hydrological and hydraulic characteristics of developments within the city that are more than two acres and/or located within a FEMA designated flood zone. Any development within a flood zone requires a technical drainage study that shall be approved by the city, Regional Flood Control and FEMA prior to the city allowing permits for construction. The city requires a letter of map revision (LOMR) from FEMA once the project is complete to reflect the actual change to the flood zones. The city adds a $50,000 line item to the improvement bond to make sure that the LOMR is provided. We use a checklist submittal process to screen drainage studies submitted for review. 

View our Minimum Drainage Study Checklist that must be completed by the engineer and submitted with the technical drainage study. An electronic copy of the complete submittal is required to be submitted with one original hard copy of the study.

The engineer preparing a drainage study must meet with the Flood Control Staff to preview the study prior to the city accepting it for review. Call 702.229.6541 to set up an appointment to submit a new drainage study. Refer to the Public Improvement Work fee schedule for any applicable fees. Once the study is accepted, the review time is two weeks or less.

All drainage studies must follow the Clark County Regional Flood Control District Hydrologic Criteria and Drainage Design Manual. Also available is the current Clark County Regional Flood Control District (CCRFCD) Master Plan Update. These documents are available from the CCRFCD, located at 600 S. Grand Central Pkwy. Suite 300.
