The lateral lines separate adjacent usable waterway areas, and
are determined by bisecting the angles formed by the shoreline at
property corners. The following procedures shall be followed to determine
the location of lateral lines:
A. Prepare a scale drawing plot plan showing the applicant's property
and all adjacent waterfront properties within a 200-foot radius of
the shoreline owned by the applicant (See Figure A).
B. On the scale drawing, add the shorelines and harbor lines as shown
on the appropriate Zoning Map for Harbor Lines.
C. Intersect all property lines with the shoreline (Points A, B, C,
D, E, F, on Figure A).
D. From the applicant's property line-shoreline intersections (Point
D, E, on Figure A) intersect a 200-foot radius with the shoreline
(Points 1 and 2 on Figure A).
E. From the applicant's property, connect all property line-shoreline
points, ending at points 1 and 2 with straight lines (D to C, C to
B, B to 1, E to 2 on Figure A).
F. Bisect the angle formed by these straight lines and extend the lines
bisecting the angle from the shoreline to the harbor line. These are
the lateral lines (B-G, C-H, D-l, E-J on Figure A).
G. If a marine facility is proposed within 50 feet of a lateral line,
the plot plan shall be prepared by a Registered Engineer, Landscape
Architect or Registered Land Surveyor.
The usable waterway must be determined for all properties having
a pair of lateral lines as shown on the applicant's drawing. For an
acceptable usable waterway area, the following conditions (See Figure
A) must be met:
A. If any pair of lateral lines extended to the harbor line results
in a distance of 25 feet or more on the harbor line (Lines G-H, H-I,
I-J) these lines and the harbor and shore lines define the usable
waterway area for the applicant.
B. If any pair of lateral lines extended to the harbor line results in a harbor line segment (G-H, H-I, I-J, Figure A) of less than 25 feet, the lateral lines are unacceptable and shall be modified in accordance with Section
9-5.03.
C. If any pair of extended lateral lines intersect before reaching the harbor line, the lateral lines are unacceptable and shall be modified in accordance with Section
9-5.03.

When lateral lines are amended in accordance with the following
requirements, the amended lateral line(s), the harbor line and the
shoreline shall define the usable waterway area for the property.
A. Where a conflict occurs as outlined in Section
9-5.02, the lateral lines shall be modified as shown on Figure B. A line shall be moved toward the shoreline and parallel to line D-E, (Figure B) until a 25-foot clearance is obtained (Line N-O, Figure B).
B. Two additional lateral lines N-P and O-Q will be drawn perpendicular
to line N-O from points N and O to the harbor line. The lines D-N-P,
E-O-Q are the new lateral lines for the applicant's parcel and the
adjoining properties.
C. For all amended lateral lines, construction will be limited to the
area enclosed by the shoreline, the lateral lines (D-N, O-E) and the
imaginary clearance line N-O (Figure B). This procedure will insure
adequate clearances for adjacent piers.
D. When a lateral line restricts the amount of useable waterway area,
the lateral line may be amended if a plat is prepared by a Registered
Engineer, Landscape Architect or Registered Land Surveyor, indicating
the purpose of the plat and depicting the amended lateral line(s),
along with the appropriate recording forms. The plat shall be recorded
in the land records of Calvert County with signatures of all the owners
of the lots or parcels affected by the change and the Secretary to
the Planning Commission.
