Conditional review. If Paragraphs [1][a], [b],
[c], [d] or [e] of this subsection prevents approval or the extension
of a previous approval of a preliminary subdivision plan or site plan,
the Department of Planning and Zoning may proceed with conditional
review of the plan and place it on a waiting list arranged by date
of completion of the review and, for previously approved plans, by
date of the request for extension. Record plats, grading permits and
public works agreements for utilities or roads shall not be executed
by the County until the plan for the project is removed from the waiting
list and preliminary approval or extension of the previous approval
is granted. Removal from the waiting list shall occur only when the
condition that prevented approval under Paragraphs [1][a], [b], [c],
[d] or [e] of this subsection no longer exists.
