Document Description
Project proposes a multidisciplinary approach to integrate multilayer piezoelectric orientation structures to create roadway piezoelectric energy harvesting systems with high power density and efficiency such that over 50% mechanical energy can be harvested as electricity. The energy harvesting system is designed to achieve an electrical energy density of 333 W/sf with the cost reduced to $9,010/kW.

15301, 15304
Reasons for Exemption
This project will occur at an existing, paved parking lot within the UC Merced campus. The project will design a piezoelectric roadway energy harvesting system integrated with multilayer cylinders to capture compression mechanical energy from passing vehicles. The project will involve a concrete base to support the piezoelectric elements, a nylon based road surface layer to protect the system as part of the road payment, and interface grid, with spaces filled with lower elastic modulus polyurethane for water resistance to protect the piezoelectric elements and circuits from moisture and rain. This system will be demonstrated by building a section of road about 95 ft long by 12 ft wide on the edge of the existing parking lot. There will be negligible expansion of the existing parking lot's use. Therefore, the project will have no significant effect on the environment and falls under CCR, Title 14, sect., 15301.
This project will construct a relatively small roadway on land occupied by an existing, paved parking lot. Minor grading and trenching may occur, and no healthy, mature scenic trees will be removed.
