Which of the following is generally not a responsibility of the zoning board of adjustment?

The responsibility of implementing zoning changes typically falls under the purview of the municipal governing body or planning board rather than the zoning board of adjustment. The zoning board of adjustment is primarily tasked with reviewing specific applications for relief from zoning ordinances. These responsibilities include hearing appeals from decisions made by administrative officers and granting variances, which allow applicants to deviate from strict compliance with zoning regulations in certain circumstances.

Evaluating site plans is generally a function of the planning board, which assesses proposals to ensure they comply with the community's master plan and zoning regulations. The zoning board's focus, on the other hand, is on individual requests for variances or appeals rather than altering or implementing the zoning ordinance itself.

Thus, the correct answer highlights the specific role of the zoning board of adjustment in the context of land use and planning practices, distinguishing it from the broader responsibilities of implementing changes in zoning regulations.
