[Amended 2-22-2024 by L.L. No. 4-2024, effective 2-27-2024]
The preliminary layout and the supporting documents
for a proposed subdivision constitute the material to be officially
submitted via delivery to the Department of Planning, Environment
and Land Management. The layout shows the general design of the subdivision
and its public improvements so that the Planning Board can indicate
its approval or disapproval of the subdivision prior to the time that
the final plat, including the design and detailing of the public improvements
and utilities, is completed. Approval of the preliminary layout does
not constitute an approval of the final plan, nor should it be considered
a valid basis for the construction of site improvements or for other
commitments which depend upon its design characteristics.
[Amended 2-22-2024 by L.L. No. 4-2024, effective 2-27-2024]
A. Before starting the engineering and surveying work,
