Next Gen 911 Addressing 5,000 miles of digitized, routable, paved road

network 635 miles of additional GPS, routable, unpaved

road network

Interactive Web Mapping Tool

Parcel Fabric creation

Nation-wide Flood and Wildfire Risk dataset

Physical Assessment data integration

Gold King Mine data repository

Outreach videos in English and Navajo languages

APPLICATIONS

Floodplain Studies and Drainage Design

Mapped over 6,000 miles of floodplain using imagery, DEM, and Hydrologic & Hydraulic (H&H) modeling

Created Flood Depth Grid color maps from H&H modeling output

Produced Hazard Mitigation Plan using flood and wildfire data from LIMS

Developed a Drainage Design Manual as guidelines for development

Modeled 3D perspectives and flythrough videos

Produced training and outreach videos in English and Navajo languages

APPLICATIONS

Wildfire Risk Analysis

Parameter 1 – Fuel Load/Vegetation USGS National Land Cover Dataset

Parameter 2 – Slope NHA DEM

Parameter 3 – Aspect NHA DEM

Parameter 4 – Past Fire Occurrence Federal Fire Occurrence Data

ArcGIS Modelbuilder Automation Raster reclassification and weighting

Navajo Nation-wide Raster Grid displaying Wildfire Risk Potential

APPLICATIONS

Assayii Lake Fire – Incident Command Support

14,712 acre wildfire (June 13 - July 3, 2014) Structures threatened: 135 Outbuildings lost: 4 Residences lost: 24 Total fire personnel at incident peak: 867 No significant personnel injuries or claims

Provided essential data support to Southwest Area Incident Management Team.

Using data from the LIMS, developed 3D flyover video presentation as a tool that transcends language.

The flyover took the understanding of a fire to a new level and made a substantial contribution toward the strategic suppression of the wildfire.

APPLICATIONS

Floodplain Mapping Using Drone Technology

To save cost and time, AECOM used a drone to collect 250 acres of 3D detailed terrain, producing 0.5 foot DEM capable of 3 inch contours.

Mapped multi-branched alluvial floodplain using 2D modeling – FLO-2D.

Using new technology and LIMS information, the result allowed for informed subdivision planning and housing reconstruction decisions in Whippoorwill, AZ.

APPLICATIONS

Environmental Assessments and Planning

Assessed available land for feasibility of development using LIMS datasets, such as:

Floodplains/Wetlands Cultural Sites & Endangered Species Areas Overhead transmission line easements Underground pipeline easements Terrain/Soil/Geology Infrastructure

Performed environmental assessments and cultural assessments to make decisions on land purchases and subdivision planning in Merrill Crater, AZ and Yah-ta-hey, NM.

Performed HUD 8-step decision process for mitigating risk in and around floodplains to make decisions on subdivision expansions and housing modernizations in Cornfields, AZ, Chinle, AZ, and Ojo Amarillo, NM.

APPLICATIONS

Physical Needs Assessment

Collected asset management data in the field via tablets and integrated the data into the NHA LIMS.

Assessments include: geotechnical, architectural, mechanical, electrical, plumbing, infrastructure, drainage, UFAS adaptability, and sewer.

Used industry standard facility condition index (FCI) to rate, prioritize, and cost housing repairs.

Asset Management is a continuous process, so working toward developing a system to assess inventory, plan maintenance, implement repairs, and integrate updated data back into the system.

Designed Web Dashboard to quickly access and query condition assessment data.

APPLICATIONS

Road Alignment and Design

Using LIMS data, engineered cost effective feasible road designs taking into account multiple constraints, such as:

Environmental/Endangered Species Cultural Sites Floodplains/Drainage Mitigation Alternatives Terrain/Slope/Sight Distance Community Preferences NDOT and BIA Requirements Buried utilities ROWs Maintenance

Used 3D rendering for design perspectives, community outreach, and stakeholder decision making in Mitten Rock, NM.

2015 ESRI SAG AWARD WINNER

SUMMARY NHA has advanced its mission and improved business operations through its

Data Center and Land Information Management System (LIMS).

The LIMS allows for efficient use of applications such as: Floodplain Studies and Drainage Design Wildfire Risk Analysis Use of New Drone Technology Environmental Assessments and Planning Physical Needs Assessment Road Alignment and Design

NHA continues to build upon its Data Center technology, communication utilities, and LIMS to create essential business and management systems.

Using this technology NHA can plan and develop sustainable communities to meet the housing needs of the Navajo Nation for many generations to come.

NHA wants to share its successes to generate ideas and help empower your business and communities as well.

THANK YOU!
