Drawing from Communicative Planning Theory (CPT), this paper examined planning interface for social service delivery between Local Government Authorities (LGA) and Corporates in Morogoro region using a case study design. Results revealed that LGAs planning process was inclusive and transparent enabling corporates to decide on kind of services to provide to communities. Conversely, Mtibwa Sugar Company was not transparent to share their planning decisions with the LGA whereas Kilombero Sugar Company was transparent in sharing their planning decisions to the LGA. Hence, LGAs planning processes are in line with CPT, which considers inclusiveness and transparent as core components for effective planning. The findings further revealed misalignment of planning seasons between the LGAs and corporates leading to double allocation of resources for some social services. The study recommends that there should be budget review by the LGA to relocate resources that corporates use to support community activities.
