This documentation presents guidelines for use of the automated social and economic component (SEC) of the activity assessment routine. The SEC provides a mechanism for estimating the effects of development activities on social and economic systems of the Texas coast. The social and economic component of the AAR was developed at t the direction of the governor of Texas and the state legislature. It is primarily for use in the permitting process by state agencies which have responsibility for coastal resources. In addition to its use by state agencies in permitting, the SEC will be useful to local officials in planning to meet expected impacts of proposed development.
