Clark County Councilor David Madore’s repeated and ongoing accusations of wrongdoing by the county planning director, planning staff and county prosecutors are false, according to the results of a nearly four-month investigation released Wednesday afternoon.

Rebecca Dean, a Seattle attorney, has been investigating questions and attacks Madore and County Planning Director Oliver Orjiako have leveled against each other over Clark County’s Comprehensive Growth Management Plan update since March. The investigation cost $54,936.97, according to a county news release. Dean charged $240 an hour.

Madore has accused county staff of insubordination and lying about the impact of his proposed zoning map, Alternative 4, and a later version, Alternative 4B. Madore’s proposal, which was rejected by the council earlier this year, would have allowed for the creation of thousands of lots in rural Clark County.

But in a 40-page summary of the 400-page investigation, Dean reports that Madore’s accusations that Orjiako and Deputy Prosecutors Chris Cook and Chris Horne lied to the county council in order to pursue an “anti-rural growth agenda” are “in all material respects,” false. Madore’s allegations that county staff interfered with the work of R.W. Thorpe and Associates — a planning consultant Madore hand-selected to review his policies — are also false, Dean said.

“Orjiako, the Planning staff, Cook and Horne did not engage in any behavior intended to mislead or deceive the (Clark County council), … manipulate data or manipulate the outcome of the Thorpe Review,” Dean concluded.
