(A) The assessable buildable unit method shall be adopted for direct benefits. The area assessment method shall be adopted for overall area benefits. These two methods will include all costs and assessments.
(1) The assessable buildable unit shall be defined as an existing constructed single-family residence, constructed on an allowable sized lot according to zoning, and which is benefitted by the improvement.
(2) The overall area benefit charge shall be based on the actual square footage of area involved, or 30,000 square feet per buildable unit, whichever is the smaller figure.
(B) Properties which are vacant, either of allowable size, according to zoning, or potentially allowable size, and on which a use has not been established, shall be considered as subject to deferred payment assessment which will be properly documented in the land records to protect the town for future assessments when property is put to use.
(C) Existing uses of properties other than single-family residence will be converted to buildable units for assessment purposes in accordance with the following rules.
(1) Multiple dwellings. One buildable unit for the first unit and thence:
0.25 unit for each additional one-bedroom unit;
0.50 unit for each additional two-bedroom unit;
0.75 unit for each additional three-bedroom unit.
(2) Commercial property. One buildable unit minimum for the first 1500 square feet or less of possible buildable area based on zoning requirements to the maximum of 30% building to lot coverage of the buildable area of the lot, thence 1/15 of a buildable unit for each 100 square feet of additional buildable area.
(3) Manufacturing property. One buildable unit minimum for the first 10,000 square feet or less of possible buildable area based on zoning requirements to the maximum of 50% building to lot coverage of the buildable area of the lot, thence 1/10 of a buildable unit for each 1000 square feet of additional buildable area.
(D) On all shapes and sizes of property, the foregoing rules shall govern insofar as applicable. The Water Pollution Control Authority shall have the discretionary power to apply a method of determining assessable units in all questionable cases.
(E) Rates for assessable buildable units and for overall area benefit charge shall be established by the Water Pollution Control Authority for each assessment district.
