The importance of a land use plan cannot be overemphasized hence its inclusion in the requirement for the establishment and continuous accreditation of any tertiary institution by the regulatory bodies in Nigeria such as the National Board for Technical Education, National University Commission, and National Commission for Colleges Education. Pursuant to this, the Waziri Umaru Federal Polytechnic commissioned its department of Urban and Regional Planning to prepare a land use plan as a guide for the development of her permanent site. The beauty of any plan is in its implementation and tertiary institutions are seen as models in midwifing theory and practice and should be above board in the implementation of its development plans. Eleven years after its approval by the Management of the institution, there are observed deviations from the provisions of the plan, which necessitate this research that seeks to determine the extent of deviation. The paper relied on information and spatial data from the Waziri Umaru Land Use Plan 2010, googleearth pro high resolution image and coordinates obtained using differential Global Positioning System to establish areas of deviation in the implementation of the plan. Explanations for deviations came through interview of the officials of the Physical Planning Department (PPD) and the management of the institution. Results revealed gross deviation from the proposals where the sizes of lands proposed in the plan where not complied with; change of location of proposals without recourse to the plan, introduction of items that were not initially captured in the plan among others. Reasons for deviation included but not limited to the following: poor understanding of the provisions of the land use plan; non-recruitment of planners to help interpret the land use by the PPD; and poor funding. A review of the land use plan is recommended and employment of planners in the PPD should be mandated as ways of curbing future deviation and ensuring sustainable development.
