Citizens Technical Advisory Committee Meeting July 22, 2015 Financial Management No.: 433627-1-22-01 Efficient Transportation Decision Making No.: 9892 SR 90/SW 8th Street at SR 973/SW 87th Avenue Project Development and Environment Study </li><li> 2. Goals of a PD&amp;E Study Develop and evaluate engineering and environmentally feasible alternative solutions that meet the need determined in the Planning Phase Evaluate potential impacts to the social, natural, and physical environments and determine ways to avoid or minimize impacts Inform and involve the public in the development of the project alternatives Process is mandated by the National Environmental Policy Act (NEPA) and state law. Represents a combined effort by technical professionals who analyze information and document the best alternative for a communitys transportation needs. 2 </li><li> 3.
