[ARCHIVED] Brookings Responds to Major Rain Event

Heavy rains Monday night and early Tuesday resulted in several major street flooding events and damage to private property in Brookings, City Manager Gary Milliman reported.

The control panel for the Beach Avenue sewage lift station slid down a cliff toward Ransom Creek Tuesday afternoon, disabling the facility and causing a discharge of sewage, while a large sink hole and storm drain pipe collapse has resulted in the closure of Ransom Avenue between Sixth Street and Fern Avenue.

City Public Works and Treatment Plant crews, Fire Department volunteers and employees, Police Officers and Development Services Department staff responded to several dozen significant calls for service due to building and street flooding.

The Napa Auto Parts store and an adjacent shop building flooded, the Rush Building suffered a partial roof collapse and several residences also reported flooding. Water levels reached within a few inches of the front door of Fred Meyer. Water was over the curb at several locations along Chetco Avenue and the Railroad/5th Street intersection was impassable. Crews cleared away a large amount of debris on Old County Road near Marine Drive. Crews also filled and placed sandbags at various locations throughout town. The new Civic Center drain performed well, although there was a build-up of water in the parking lot behind the building, and rear entrances to the City Hall and Police Station were sandbagged.

The most serious damage to public facilities was the collapse of a section of 72-inch storm drain pipe on both sides of Ransom. A sidewalk, landscaping trees and smaller storm drain pipe collapsed into the sink hole. A wall adjacent to the Brookhaven residential community is also in danger of collapse. The City will be deactivating a section of 10-inch water main that is now suspended across the sink hole, and some water customers will be affected temporarily.

The City Engineer is currently evaluating the Ransom condition, and work will begin later today to clear debris from the sink hole. The entire collapsed pipe will need to be replaced, and there are many other utilities in the street that will need to be avoided.

Access to the Brookhaven community will remain open from Ransom Avenue just east of Sixth Street. Pedestrians are discouraged from entering the area as it is unsafe. All traffic, including children going to school, should use alternate routes, such as Easy Street.

A 42-inch storm drain culvert on Mill Beach Road at Sandy also collapsed. Milliman authorized emergency contracts with Tidewater Construction and McClennan Construction to restore the collapsed culverts.

“Our major concern at this point is North Bank Chetco River Road. We have been advised that the road may be blocked by slides and may experience wash-outs at several locations. We are preparing a plan to shut down the water line coming into town to avoid water loss in the event of a washout,” Milliman said. “The water intake is inaccessible, but all of our water storage reservoirs are full.”

Approximately six houses suffered flooding in the Alder/Memory Lane/Buena Vista Loop area. Building Official LauraLee Snook is gathering information on damage to private property. Brookings residents who have experienced property damage should contact Snook at (541) 469-1131.

The wastewater plant was running at near capacity for several hours. Power was out to 10 of the City’s pump stations, all of which had to be manually monitored for periods of time.

The Public Works Department reports that they recovered pieces of plywood from the ditch/creek behind Napa Auto Parts. This debris was blocking the entrance to the culvert, resulting in an overflow of water through the Napa store and over to Lucky Lane, across the highway, through the commercial development behind the Thai restaurant and into the Fred Meyer parking lot where it pooled to near the level of the entrance and then around to Railroad Street where it joined a flow of water moving across the U.S. Bank parking lot.

“Our storm drain system was simply overwhelmed by the volume of water delivered by this storm,” Milliman said.

Milliman contacted Sheriff John Bishop and County Emergency Services Manager Don Kendal on Tuesday to request that the Board of Commissioners adopt an emergency declaration that could lead to making storm damage victims, both private and public, eligible for state and federal disaster assistance funding.
