Above: an aerial image of the northwest drainage channel dated March 28, 2015; the channel was unimproved south of the north end of the runway. Below: progress on channel improvements as of April 27, 2016, not long after the project began. The channel was improved with concrete side slope protection throughout its length, which will improve drainage and reduce recurring maintenance costs associated with mowing and periodically cleaning out the channel. The northwest drainage channel project was completed at the end of August 2016. Funded mainly by storm water fees, the project cost just under $800,000.
Above: final inspection walk-through of the channel. Below: watering the sod and grass in disturbed areas along the southern section of the drainage channel. Below, left: the completed channel improvements looking south from the headwall at the south end of the box culvert which crosses under the northwest corner of the Runway Safety Area (RSA). Below, upper right: the view to the north from approximately the same location. Bottom right: a channel crossing was included near the north end of the field.
