penalties and conditions as the Commission may require, all of which

516. (g) Said benefits shall be levied for both water supply and
sewerage construction and shall be based for each class of property
upon the number of front feet abutting upon the street, lane, road,
alley or right-of-way in which the water pipe or sewer is placed;
provided, however, that in the case of any irregular shaped lot abut-
ting upon a road, street, lane, alley or right-of-way in which there is
or is being constructed a water main or sewer at any point, said lot
shall be assessed for such frontage as the Commission may deter-
mine to be reasonable and fair; and provided further that no lot in
a sub-division property shall be assessed on more than one side,
unless said lot abuts upon two streets which are two hundred feet or
more apart, that corner lots, irregular lots and water front lots may
be averaged and assessed upon such frontage as the Commission may
deem reasonable and fair, and that all lots in this class shall be
assessed even though a water main or sewer may not extend along
the full length of any boundary. Industrial or business property may
be assessed on more than one side; provided that the additional side
is being used for a separate and distinct industrial or business enter-
prise.

516. (h) And provided further, that no land so classified as
agricultural, large tracts of land, swamp lands, low lands, public
parks, and cemeteries [, race tracks, ball parks and other athletic
fields] owned by religious or charitable organizations, by this Com-
mission shall be assessed a front foot benefit when such land has
constructed through it or in front of it a sewer or water main, until
such time as a water or sewer connection is made, and when so made
and for every connection such land shall become liable for a front foot
assessment for such reasonable frontage not exceeding three hundred
feet, as may be determined by said Commission, and shall immediately
be assessed at the rate of assessment determined by said Commission
for such land; and provided further, that no land so classified as
airport property by this Commission shall be assessed a front foot
benefit when such land has constructed through it or in front of it a
sewer or water main, until such time as a water or sewer connection
is made, and when so made such land shall become liable for a front
foot assessment for a frontage not exceeding 1,000 feet.

Arundel County Sanitary Commission, Glen Burnie, Maryland [the
County seat of government, and among the land records of Anne
Arundel County, and the Clerk of the Circuit Court for said county
shall furnish such space as may be necessary to keep and preserve
such records,] as a public record, which when [published in said
public record] so kept shall be legal notice of all existing liens within
[any] the Sanitary District, and the Commission shall keep among
the land records of Anne Arundel County a plat of each area served
by the Commission, and the Clerk of the Circuit Court of said County
shall furnish such space as may be necessary to keep and preserve
