(a) Notwithstanding any other provision of law, subsequent to the creation of an easement for a roadway connecting to Mulholland Drive through the Mulholland Scenic Corridor and Topanga State Park or other state-owned parkland, the department may impose conditions and restrictions on the development of the roadway thereon and upon contiguous portions of Mulholland Drive if the director finds that geologic or other circumstances exist which cause or may cause substantial damage to state-owned park resources. (b) Notwithstanding any other provision of law, these conditions and restrictions, including the imposition of, and compliance with, these conditions and restrictions, shall not constitute a new project or otherwise affect the validity of recorded tract maps or other entitlements, shall supersede, preempt, and replace any conditions, restrictions, or other requirements imposed on, or in connection with those tract maps and other entitlements to the extent inconsistent with these conditions and restrictions, and shall not in any way jeopardize previously approved projects or cause a reopening of a previously completed environmental review process. This subdivision shall not be of any legal effect, for the purpose of superseding and preempting any locally imposed conditions, unless the owner of the property subject to locally imposed conditions shall pay the amount of the estimated cost savings as a result of superseding the locally imposed conditions to the Los Angeles County Transportation Commission for traffic mitigation within the San Fernando Valley Statistical Area, as defined in Section 11093 of the Government Code, on or before December 31, 1991.
