As a civil consultant to Spark Spiritual, Architects, CGA Engineers prepared plans for the development of a 38-acre campus for the relocation of the Evergreen Baptist Church. The design task included grading, drainage, utilities, surfacing, erosion control and stormwater management.
Unique to this project was the development of a 2-acre retention pond that was used for stormwater management from both the church site and a proposed subdivision that lay on both the north and west sides of the church property. The pond was incorporated into the landscaping of the site and included a control structure to retain a base pool year-round. Additionally, the pond had a walking and jogging trail added to the top bank for church members' recreational use. An additional pond was also designed as a reserve area since the grades did not allow all the drainage to flow into the retention pond.
Utilities included extending both the waterlines and the sewer lines into and adjacent to the property. The waterline was looped through the property for redundancy and to meet regulatory requirements. Fire hydrants were included for fire safety along with connections to the building's sprinkler system. A new sewer line was run on the back property line that services both the church and future developments.
The construction plans were prepared as part of the platting process for the City of Broken Arrow. The plat included the utility easements and the dedication of right-of-ways and reserve areas.
