The Planning Commission’s vision is to oversee the orderly growth and development of the County, seeking to balance economic growth with environmental protection and historic preservation.

The Nassau County Planning Commission is mandated by law to approve subdivision of land within the unincorporated areas of the County and offer recommendations to municipalities on zoning referrals. The Planning Department staff processes and reviews subdivision applications and zoning referrals, and makes recommendations to the Planning Commission. The Department is also charged with advising the County Executive, the County Legislature, and County departments in regard to the physical development of the County.

The Planning Commission consists of nine members appointed by the County Executive. The County charter stipulates that all Commission members must be residents of Nassau County, and that the Commission must include at least one resident from each of the County's three towns. The charter also requires that certain interests 'environmental, business, and minority' be represented on the Commission. The term of office for Planning Commissioners is three years.
