Inquiry

The City of Little Rock Code for Irrigation requires an irrigation system for developments of one acre or larger. The irrigation system will not be connected to the City of Little Rock potable water system. Rainwater will be collected from the roof into a catch basin. The catch basin will hold 8,000 gallons of captured rain water. The catch basin is connected to a marina which is part of the site. The marina is a dock and access off the Arkansas River through a lock gate. All excess water from the basin is diverted into the adjacent marina. Once the 8,000 gallons of water held in the catch basin is used for irrigation, water is pull from the adjacent marina. A pump and filter will be provided to pull water from the marina and continue through the irrigation system consisting of conventional spray heads and drip irrigation. The marina is maintained to a relatively constant level by mechanical means. Approximately 80% (44,000 sf) of the site landscape contains a native vegetation with minimal to no irrigation. The remaining 20% (11,000 sf) not native to the state has similar water use requirements. Does this design qualify for WE credit 1.2?
