Document Description
The project is limited to the development of 10.9 acres for a single-family residential community. A 24-inch storm drain along and within the northern bank of Santiago Creek, on the north-eastern corner of the project site, will be installed as infrastructure for the residential community. The outlet will consist of a concrete headwall followed by about 68 cubic yards of riprap. In order to allow equipment to access the southern portion of the site, a temporary earthen crossing will span Santiago Creek for the approximately 3 years until construction is complete. The crossing will sit 12 feet above the Santiago Creek bed, span 20 feet wide, be constructed out of approximately 1,668 cubic yards of fill, and will have a reinforced concrete pipe 36 inches in diameter placed underneath the bridge to facilitate Creek flows. The crossing will be removed after construction.
