890 LAWS OF MARYLAND. [CH. 357

on the bonds or certificates of indebtedness so issued by the
Mayor and Town Council for the construction of drainage
systems, there shall be levied by the Mayor and Town Coun-
cil a special assessment to be known as a drainage system
assessment against all of the properties within said drainage
area served by said system, whether immediately or remotely,
which the Mayor and Town Council determine to be specially
benefited by said system, based on the area or on the assessed
value of all of the property belonging to any owner within
said drainage area and so benefited, which tax or assessment
shall be uniform throughout the area affected. The special
assessment aforesaid shall be on either an area basis or on
an assessed value basis, whichever is deemed more equitable
and just by the Mayor and Town Council of Cheverly, and
such selection as made by the Mayor and Town Council shall
be final and conclusive. Such tax or assessment shall be
levied annually in a sufficient amount to meet the principal
and interest requirements of the bonds outstanding, the pro-
ceeds of which went into the construction of the drainage
system and such tax or assessment may be graduated from
year to year as the bonds are retired, provided however, be-
fore any such tax or assessment is levied the Mayor and
Town Council of Cheverly shall mail to the best obtainable
addresses of the owners of all properties within said drainage
district or part thereof upon which it is proposed to levy a
tax or assessment, notice that said tax or assessment is to
be levied and giving said property owners an opportunity to
be heard thereon at a time and place fixed in said notice, and
at said hearing the Mayor and Town Council may adjust
said tax or assessment, maintaining however, a rule of uni-
formity as to the base rate or percentage of levy. Such levy
or assessment when made shall constitute a tax lien upon all
of the properties within said drainage area, as determined by
the Mayor and Town Council of Cheverly, and shall bear
interest at a rate not to exceed six per centum (6%) per
annum from and after thirty (30) days from the date of each
annual levy or assessment, and any assessment or part
thereof, including interest and penalties remaining due and
unpaid, shall be enforced and collected by the Mayor and
Town Council in the same manner as town taxes are now
enforced and collected, as now or hereafter prescribed and
required by law.

SEC. 7. And be it further enacted, That no drainage plan,
system or design shall be adopted, or any drainage system
constructed, except for the protection of an individual's home,
by any person, firm or corporation unless such plan or design
