Document Description
Preliminary design activities include evaluation and assessment of the site geotechnical conditions; establishment of site-specific earthquake motions; seismic design analyses; evaluation of alternatives to optimize the recommended retrofit; development of final design criteria and repair measures for the leaky expansion joint; preparation of environmental documentation; preparation of a preliminary design report; and development of a construction cost estimate.
The proposed project consists of the operation, repair, maintenance, permitting, leasing, or minor alteration of existing public or privat structures, facilities, mechanical equipment, or topographic features, involving negligible or no expansion of use beyond that existing at the time of the lead agency's determination.
