• floodplain. The T1 terrace is generally quite narrow, has very <br />little soil present and consists primarily of coarse boulders, <br />cobbles, and gravel deposits remaining from the original mudflow <br />and from Rapid Creek. Therefore, the Tl terrace of Rapid Creek <br />does not have the potential to be developed for flood or <br />subirrigation agricultural activities. <br />The T2 terrace is one of the more prominent terrace <br />landforms present on both sides of the lower Rapid Creek Valley. <br />At a point approximately .5 mile below the confluence with <br />Cottonwood Creek, the Rapid Creek valley decreases significantly <br />in width (i.e., less than 50 feet wide). Above this point the <br />Rapid Creek Valley does not have the potential to be developed <br />for agricultural use. Downstream of this point, the terrace <br />• occurs approximately 2 to 10 feet above Rapid Creek and increases <br />in width in a downstream direction to approximately 250 feet wide <br />near the mouth of Rapid Creek. The T2 terrace, where it has <br />not been developed, is composed primarily of the debris <br />(boulders, cobbles in a fine matrix) from the mudflow, although <br />the terrace landform has been obviously formed through erosion by <br />Rapid Creek. <br />A T3 terrace was identified as part of the Rapid Creek <br />valley complex along the lower reaches of Rapid Creek. This <br />upper terrace is present on the south side of the valley, <br />approximately 50 feet above the T2 terrace. The undeveloped <br />portions of the T3 terrace are very similar to the T2 <br />. terrace, characterized by boulders and cobbles in a finer soil <br />3 <br />
