A development plan is a comprehensive record of a development project, initially submitted as a proposed estimate of how a project could be developed, and that will in time evolve to become a record of what was actually developed. A plan shall be submitted for any development of three or more lots, parcels, tracts, properties on which is shown the existing and proposed conditions, including, but not limited to, topography, vegetation, drainage, floodplains, wetlands, waterways, landscaping and open spaces, walkways, entrances and exits, circulation, utility services, lot lines, easements, structures and buildings, signs, lighting, parking, screening, surrounding development, and any other information that may be reasonably required by the Town to make an informed decision on the proposed project. Before too much time and money is invested in the creation of a development plan, the Town encourages developers to submit a concept plan to the Town Manager, the Commission, and the respective elected officials to establish the general viability of the proposed project.
