SUBREGION ONE MASTER PLAN AND SMA (p)(f) This project is to develop a new master plan and sectional map amendment (SMA) for Subregion I to replace the current plan that was approved in 1990. Subregion I is approximately 39.74 square miles and consists of four planning areas—60, 61, 62 and 64—located in the northeastern area of the county. The City of Laurel is not included in Subregion I since the city has its own planning and zoning authority. Nov 10, 2006 in Public bookmarkswith 1developmentnearbypgsubregion
