Some tidel<strong>and</strong> properties converted to transportation use.<br />
The existing l<strong>and</strong> use of some parcels could be changed temporarily to stage construction equipment <strong>and</strong> supplies.<br />
Increased dem<strong>and</strong> for residential l<strong>and</strong> uses; increased dem<strong>and</strong> for<br />
transportation, commercial, <strong>and</strong> industrial l<strong>and</strong> uses.<br />

transportation, commercial, <strong>and</strong> industrial l<strong>and</strong> uses.<br />
Cumulative impacts in the Mat-Su would result in increases in developed l<strong>and</strong>. About 25% of developable l<strong>and</strong> would be developed by 2030.Of the approximate 158,000 acres of<br />
developable l<strong>and</strong> in the Mat-Su modeled area, including approximately 10,000 acres already developed, cumulative l<strong>and</strong> impacts total approximately 40,000 acres.<br />
The project is consistent with Mat-Su Borough plans including the 2005 Mat-Su Borough-Wide<br />
Comprehensive Plan. The <strong>Knik</strong> <strong>Arm</strong> Crossing project was evaluated by the Mat-Su Borough as part of their<br />
LRTP, which was adopted in 2007. Various economic development plans <strong>and</strong> resolutions of support of the<br />
