as shown on the official Zoning Map, the following rules shall apply:

Where such uncertainty cannot be resolved by application of the foregoing
rules, the Director shall determine the district boundaries.
[Zoning Order §5.030, 4-2-2008]

by the Planning and Zoning Commission and the County Council in making
land use decisions. For any application not in conformance with the
Official Master Plan at the time of submittal, the Official Master
Plan shall be amended to create conformity prior to the zoning amendment,
conditional use permit or development plan being approved by the County.

provided, no building or structure shall be erected, constructed,

Provide latitude in the location of buildings, structures, open spaces,
play areas, parking, roads, drives and variations in setback and yard
requirements;
3.
Facilitate use of the most advantageous techniques of land development;
4.
Encourage the combination and coordination of architectural styles,
building forms and relationships;
5.
Encourage the conservation of existing natural resources and maintain
the character of the County; and
6.
Limit specific uses within the underlying zoning district to a particular
development plan when it is deemed more appropriate and/or compatible
to surrounding uses, proposed or future uses or when deemed to be
in the best interest of the community to limit the uses, based on
existing and/or proposed traffic conditions and/or concerns and other
land use concerns.
B.
Development Plan Regulations And Requirements.
2.
A development plan shall establish regulations and restrictions that
are in harmony with the general purpose and intent of this UDO, but
in a manner that allows the regulations to differ in one (1) or more
respects from the zoning regulations that are generally applicable
to the underlying zoning district(s).
C.
Allowable Modifications To District Requirements.
1.
Modifications in the amount of open space, lot size, buffer zone,
yard, parking, play area, density, floor area ratio and height requirements
shall be determined by the County Council after recommendation by
the Planning and Zoning Commission.
2.
The County Council shall use the requirements and standards found
in the underlying district as a guide in approving modifications from
the district requirements and standards. These modifications are granted
in the interest of efficient land development and utilization, if
it is deemed that amenities or conditions will be gained that are
equal or higher in quality.
