State Overview

• Gross Land Area (with water):– 685,000 Acres– 1,070 Square Miles

• Net Land Area (without water)– 660,000 Acres– 1,030 Square Miles

Motivation and Goals

• Since Land Use 2025:– 2003/04 and 2011 new orthophotography

• Use new land use data to:– Continue to track urbanization– Manage impacts on (1) the economy, (2) transportation, (3) urban development

Consequences of Methods

• Methodology best reflects changes in Medium to Low Density Residential Development

• Emphasizes “sprawling” nature of development

• Allows us to compare Medium to Low Density Residential Development across surveys

Definitions and Interpretation

• Land use change is new development

• Hot spots represent where development is concentrated

• Hot spots look at where development occurs most frequently between surveys

Before the USB: Development from 1995 to 2003/04

• Utilize the conservative land use definition

• Is development clustered or dispersed?

• Where is clustering occurring?

• Global Moran’s I and Hot Spot Analysis

After the USB: Development from 2003/04 to 2011

• Use a more precise definition of development

• Compare conservative vs precise

• Isolate Medium to Low Density residential development

• Compare residential development across surveys

Overview of Thesis

• Hot spot analysis– Where new development occurred

• Excel summaries– How much new development occurred

• Where development occurred after USB

Page 26: 1988 2011 Land Cover Analysis Use Land Cover...2016/09/02  · 1988‐2011 Land Use/Land Cover Analysis Cyrus Maden Nancy Hess State Overview • Gross Land Area (with water): –

Questions Left

• What factors are associated with development after the USB?

• How strong is the relationship between development and distance to the USB?

• How else can we corroborate and visualize clustering?

Grouping Analysis Overview

• We expect high develop to occur– Close to the USB– In areas with low population density– In areas with low housing density– In areas with medium population change

• We expect to see quantitative support of visual trends in the hot spots

We’re Still Sprawling

• Since 1995, we’ve experienced at least 21 sq. miles (2% of state area) of development

• We’ve experienced about 15 square miles of sprawl

• Most growth is by the USB in a “development frontier”
