Commission approves exception to 250‑foot cul‑de‑sac limit, allowing up to 500 feet for 10‑lot subdivision
Summary
Dorchester County planners approved a modification request on Jan. 9 to exceed the 250‑foot cul‑de‑sac maximum (Table 20.4.2) and allow up to 500 feet for a 10‑lot minor subdivision because wetlands and parcel shape constrain access; the modification approval does not constitute final plan approval.
The Dorchester County Planning Commission on Jan. 9 approved a modification to the county’s land development regulations that allows a cul‑de‑sac to exceed the usual 250‑foot maximum and permits a length up to 500 feet for a proposed 10‑lot minor subdivision.
Planning staff told the commission that Article 22 of Ordinance 0413 allows modifications to Articles 20 and 21 of the Land Development Regulations when strict compliance would cause extreme practical difficulties. Staff said the property’s shape and wetlands to the north limit development options and that the requested modification would not be detrimental to public health, safety or the county’s objectives. Staff recommended approval of the modification but noted that approval of the modification does not itself approve a preliminary plan; the plan must still move through the TRC process and TRC and permitting reviews.
Commissioners pressed staff and the applicant about lot sizes, utilities and emergency‑service review. Staff said the minimum lot size in R‑1 is 14,500 square feet; engineer Chris Donato said most lots are larger and estimated the smallest at about 18,000 square feet and the largest near one acre. Donato said the subdivision will have public water but on‑lot septic systems. He also said the developer expects to eliminate an existing private easement by switching access to the new public road once design is finalized; that easement and access arrangement must be resolved before final plan approval.
Staff noted emergency services is a reviewer on the preliminary plan and that no emergency‑services comments had been received as of the meeting. The commission moved and approved the modification request; the transcript records the motion and an affirmative vote.
Why it matters: The change permits a longer road to serve a small subdivision where wetlands and parcel shape limit options, but final design, easement resolution and TRC review remain outstanding.
