The former Breuner Marsh land was owned by Fred Parr in the mid 20th-century. It was/is located between the bay and
Parchester Village, and the small model plane airfield was the largest he could build, and some of the mixed wetlands—grasslands still remained. In the 1980s Bruener tested experimental aircraft, a
gyrocopter, at the site, and used it as his primary residence. Breuner Field or Breuner Airfield was a 5-acre (2 ha) private
radio controlled aircraft airfield or "flying field" and club built in the 1970s. It was located on the illegally reclaimed wetlands, at 4114 Goodrick Avenue, and was accessible from the
Richmond Parkway. The site had a sports club, some cottages, and a fishing pier. The runway was about 300 ft (91 m) and is marked with x's to state that it is not suitable for landing by any planes. It was run by the Bay Area Radio Control Society.
Bay Area Wetlands LLC Breuner Marsh was purchased in 2000 by
Bay Area Wetlands LLC, a company that planned on selling the land to the highest bidding developer. Bay Area Wetlands LLC at one point wanted to build "
Edgewater Technology Park" but were rebuffed by Parchester residents. A lawsuit was filed against the property owners to protect the open space, and the court's preliminary judgment was reached on March 28, 2008. The jury decided that the value of the was $6.85 million. This was contrary to the East Bay Regional Parks District's appraiser whom valued it at $1.5 million, and the previous purchase price the Breuners received of $3 million. The defendant owners argued that the city would make up to $18 million off the where development would be allowed. The owners were allowed to keep 20 acres (8 ha), but appealed the March 2008 decision nonetheless. A sale was finally reached two months later for the undeveloped property. ==Parkland==
