Lewis and Clark County Public Works Administrative Building Paved Parking Lot
This project is to upgrade and improve an existing unpaved parking lot in front of the Lewis and Clark County (LCC) Public Works Administration Building. The overall design will focus on providing hard-surface paving and implement Americans with Disabilities Act (ADA) provisions in the design. The first stage of design was to complete field work and soil sampling. This involved a site topographic survey and a geotechnical investigation. The geotechnical investigation included digging into the subgrade and collecting soil samples. The samples were tested for various engineering properties to be used in the design. The second phase was preliminary analyses to evaluate several potential design options, determine construction quantities, and calculate preliminary construction costs. These analyses showed us that the most practical final course of action in terms of cost and effectiveness was paving with a 3-inch-thick asphalt surface. The project will include ADA features, and parking spots will be delineated with painted striping. The construction phase of this project will have to consider the safety and health risks of the workers and the surrounding citizens. Moreover, the runoff path of any hazardous spills or water was designed to ensure that nothing potentially environmentally toxic leaves the property, and spill kits will be readily available so there is no groundwater contamination. Due to the deteriorated state of the existing gravel lot, this new asphalt pad will be a welcome upgrade that will increase safety and accessibility for all users.
