A Large Portion of Goodyear is in the Rainbow Valley Groundwater Basin
12
Goodyear’s Planning Area Includes Many Square Miles of Land in Rainbow Valley for a Sonoran Desert Lifestyle
13
Rainbow Valley’s Irrigated Lands can become Residential Neighborhoods
14
Multiple Development Plans Have Been Developed, Waiting for Buyers
