A developer can not buy a large tract of land and build whatever he or she decides to in terms of housing or subdivisions. City and county commissions usually have some sort of planning or development committee that oversees all kinds of construction and development. So much is at stake when developing or redeveloping land is concerned: the shape and size of the land, the layout of the streets, the grading and drainage of the land, and whether or not the land sits in a floodplain. More specific environmental concerns may be addressed, such as whether or not the land is home to a threatened or endangered species or whether or not the area is a key area for wildlife migrations. The quality of the water, tree and plant life must be considered, too. For the local governments, utilities must be considered: what kind of water source will the development have and who will pay for it? What about sewage? Or power? Can the development adequately be serviced by the police, fire or emergency medical transportation departments? Small streets may be quaint and inviting but could spell disaster if a fire truck can not negotiate the narrow roads. Finally, other legal matters that must be addressed include confirming rightful ownership of the land and any grandfather clauses or historical concerns that affect the legal status of the land.
