1 John Watermolen Nevada Division of Forestry

2 Project funded by a U.S. Forest Service Western Competitive grant, through the State and Private Forestry Program Thank you to Partners- City of Henderson, UNLV and Southern Nevada Water Authority (SNWA)

3 Project was designed to determine the amount of tree canopy in the Las Vegas Valley Tree inventory was also included in the project proposal and an additional ARRA grant

4 During a planning meeting, it was decided that NDF would do most of the work on a valley wide Canopy analysis. Remaining funds from the Canopy analysis would be sub granted to the different municipalities for additional work This would allow for more funding to be available for a Tree Inventory

5

6 UNLV GIS and Remote Sensing lab was sub contracted to create the different land cover layers Land cover classification schema was based on CityGreen definitions

7 Bladed Ground- This layer is composed of land that has been bladed for development. There will be no vegetation on the properties and are usually housing developments that have not been completed. City green classification- Impervious surface-unpaved-dirt or Urban Bare Barren Ground- this is barren ground. It could be next to a golf course fairway or most of a property on larger size parcels. Example if there is a 1 acres parcel with mostly barren ground and a house, just make the whole parcel barren ground. City green classification Arid and Semi Arid Rangeland Sage Brush 30-70% cover or Arid and Semi Arid Rangeland Desert Shrub 30-70% cover Open Space- This later will consist of athletic fields, golf course fairways, greens and sand traps. This could include areas next to schools such as soccer fields. City green classification Grass Scattered Trees-grass cover 50-75% or Grass Scattered Trees-grass cover >75%

8 Parking lots- This layer consists of large parking lots that would be adjacent to hotels, malls, larger schools, businesses and universities. It would also include runways and general airport lands. City Green Classification Impervious Surface-Paved-Drain to Sewer Buildings- This layer consists of residential, commercial and industrial buildings. In residential areas, complete blocks could be grouped together. In areas of partial development, group houses that are next to each other. Apartment and Condo Complexes include all parking, open space areas. City Green classification Urban or Impervious Surface-Buildings/Structures (could break this out by residential, commercial or industrial Water Features- This layer consist of any ponds in parks, water traps on a golf course, some of the large casino water features. City Green Classification would be Water Area

10 Final land classification was, using City Green descriptions: Arid and Semi Arid Rangeland- Sagebrush=Ground cover 30% to 70% Impervious Paved Impervious Drain Sewer-Roads, Parking lots Impervious Unpaved Dirt- Bladed Open Space grass/scattered trees

11 Open Space grass/Scattered trees grass cover > 75% (turf) Trees: Grass/turf understory ground cover > 75% Urban: Commercial/Business Urban: Residential Urban: Western Desert Water Area

33 A generalized zoning layer was developed by UNLV. 11 different zoning categories CityGreen analysis done for each zoning category for each entity

34 The zoning map was prepared by merging the landuse maps of the individual cities. In the merging process, careful attention was given to the merging of the different classification schemes used by the cities. Process for creating a Las Vegas valley zoning map began with researching available data of designated city land use boundaries and government zone policies. Each city website had PDF’s of their zoning map and of the building code which defines land use characteristics. Shapefiles of the zoning maps were accessible at the Clark County GIS Management Office website (GISMO).

43 Heat Island Study by UNLV-in progress Additional Canopy Analysis such as planting areas-City of Henderson-completed Tree Inventory of public tree-in progress Redo Canopy Analysis in 5 to 10 years

44 This project is an extension of Las Vegas landcover mapping project. We are develop urban thermal model for Las Vegas valley to understand the thermal entrapment that leads to urban heat islands. In this work, we are also investigating the landcover changes over last 30 years using LandSat imagery. This would help link the urban heat island development to the urban sprawl.
