CGA Engineers was selected as the civil consultant by ONE Architecture, LLC to design and prepare plans for a Reintegration Campus for the Muscogee (Creek) Nation. The 26.9 acre site is located on East Corporation Street in Henryetta, Oklahoma near the intersection of U.S. Route 75 and I-40. Initially, 12 acres of the 26.9 acre site are being developed for the Reintegration Campus of which 4.1 acres is disturbed by construction activity. The tasks included site survey, grading, drainage, utilities, surfacing, erosion control, and stormwater management.
Utilities included extending water, electrical, gas, and telecommunication lines into and adjacent to the property. The nearest sanitary sewer structure from the Reintegration Campus is located 0.4 miles away from the site. Therefore, a pump station with a force main was added to connect to the sanitary sewer system.
The site included two separate watersheds. Part of the site drained to the east, part to the west. The grading was designed in such a way as to not change the existing overland flow of water.
The site was designed to give consideration to future expansion of the building and site. The drainage around the building was designed as open channel flow, but when the proposed gymnasium is added, the stormwater will be easily converted to a closed system.
The site-grading plans are detailed and provide coordinate and elevation information for all points necessary for a surveyor to layout the construction staking. The contractor is not required to develop information from assumptions or layout the grading contours. The layout information is explicit.
