Marina Pact Renewal May Hit a Snag : Boating: Supervisors Riley and Steiner oppose proposal that county forgive $200,000 in back rent. New lease outlines $10-million development.

A $10-million development plan and lease extension for Sunset Marina in Sunset Beach could run into opposition at the Orange County Board of Supervisors today, as two supervisors say they will not forgive $200,000 in rent owed the county as a condition of the new lease agreement.

In a letter to his colleagues, Board of Supervisors Chairman Thomas F. Riley said Monday that marina operators Goldrich & Kest of Culver City should have to pay the back rent before such a lease extension is granted.

“If G&K; is willing to accept this change . . . we believe it is advantageous to begin formal negotiations and return the lease for consideration,” Riley said.

Supervisor William G. Steiner also signed the letter, which was circulated to board members Monday afternoon.

The board’s consideration comes after the county Harbors, Beaches and Parks Commission voted late last month to offer G&K; a 35-year lease extension. The firm has operated the marina since 1969.

Under terms of the proposal before the supervisors, which would replace the current lease set to expire in 1999, the county would spend $4.4 million on improvements to the marina, including an interpretive kiosk, landscaping and trails. It also would forgive $200,000 owed by the management company in back rent. In exchange, G&K; would spend $5.5 million to expand the number of boat slips from 276 to 341, increase dry boat storage from 97 to 241 spaces and increase the number of parking spaces from 190 to 280.

The new lease proposal comes to the board despite a county policy which states that such contracts, whenever feasible, should be allowed to expire and then put out to competitive bid. But county officials have said that the new agreement, if approved, would more than double the annual revenue from the marina over the next several decades.

The prospect of the county earning additional revenue through renegotiation of existing contracts is one exception to the rebid policy.

An attempt to extend G&K;’s lease was put off three years ago when it was disclosed that Lee E. Wieder, the son of Supervisor Harriett M. Wieder, whose district includes the marina, worked as a lobbyist for G&K.; At the time, G&K;’s maintenance record at the marina had been criticized.

County officials have said Wieder’s son is no longer involved and maintenance is no longer a problem.
