(20) year frequency. FLOODPLAINS AND CULVERTS SHALL BE
BASED ON A FIFTY (50) YEAR FREQUENCY. In all instances
where it is determined that a pipe greater than forty-eight (48) inch
diameter capacity (computed on the basis that n = .015) is required,
the fifty (50) year floodplain shall be provided. When pipe of forty-
eight (48) inches or less is required, pipe shall be provided and in-
stalled by the developer. Where conditions within a given subdivision
are such that the transition from a pipe to a floodplain occurs, the
developer may, with the approval of the Planning and Zoning Office,
use larger pipe in lieu of the floodplain.

(c)    Off-site easements shall be provided by the developer where
deemed necessary by the Planning and Zoning Office acting on the
advice of the Public Works Department. In the event the developer
is unable to acquire necessary easement rights outside of his property
lines, the county according to established county policy will acquire
such easements at the developer's expense. Necessary on-site easements
and all necessary on-site facilities shall be provided by the developer.
Where the developer's property abuts an existing county street or road,
drainage facilities on or under such street or road shall be considered
on-site drainage facilities and as such shall be provided by the developer
in a proportion to be discerned by the Planning and Zoning Office on
the advice of the Public Works Department.

(d)    To provide for necessary off-site storm drainage facilities
within the watershed in which his subdivision is located, the developer
shall do one of the following at the discretion of the Planning Adminis-
trator acting on the advice of the Public Works Department:

(1)   Provide for the construction of all necessary structures through
and between his subdivision and an acceptable outlet (a stream approved
for storm drainage purposes by the Planning and Zoning Office on the
advice of the Public Works Department and when necessary, the Soil
Conservation Service, or tidal water) (SEE SECTION 13-103 (1)). If such
construction has already been provided for by another developer under
paragraph (3) of this subsection, then the developer shall pay his normal
contribution as provided for under paragraph 3 of this subsection.

(2)    Commit, or have committed, all property owned, controlled
by or under option or contract to him, for a future benefit tax assessment
to be levied in accordance with Chapter 733, Laws of Maryland of 1953
(House Bill 787). This alternative may be chosen by the developer
only with the approval of the County Council on recommendation of
the Planning and Zoning Office.

(3)   Contribute, in cash, fifty dollars ($50.00) per lot for a single
or two (2) family lots and one and one-half cents ($.015) per square
foot of land area being developed in apartments towards off-site
facilities, to be paid for prior to the approval of the plat.

(e)    In commercial and industrial areas where the developer
desires to install pipe in the area normally covered by the fifty (50)
year floodplain, he may do so providing that adequate provision is
made therefor and complete plans submitted. In all cases the developer
shall assume full responsibility for carrying the storm water through
and from his property to an acceptable outlet. As an alternative, the
developers of commercial or industrial areas may contribute one
and one-half cents ($.015) per square foot of land areas being developed,
such contribution to be acceptable only at the discretion of the Planning
and Zoning Office upon recommendation of the Department of Public
Works.
