(A) (1) The maximum percentage of a residential lot that can be devoted to impervious surfaces,
as defined in §153.004, is established to assure that the character of the town is preserved and to control stormwater and runoff directed to the streets and adjacent properties.
(2) The maximum impervious coverage is proportional to the lot size. The maximum area permitted is as follows:
Lot Size (Acres) | Max. Impervious Surface (Ft.2) | Lot Size (Acres) | Max. Impervious Surface (Ft.2) | Lot Size (Acres) | Max. Impervious Surface (Ft.2) |
Lot Size (Acres) | Max. Impervious Surface (Ft.2) | Lot Size (Acres) | Max. Impervious Surface (Ft.2) | Lot Size (Acres) | Max. Impervious Surface (Ft.2) |
0.50 | 8,102 | 1.60 | 18,352 | 3.25 | 24,597 |
0.60 | 9,708 | 1.70 | 18,886 | 3.50 | 25,250 |
0.70 | 11,067 | 1.80 | 19,390 | 3.75 | 25,858 |
0.80 | 12,244 | 1.90 | 19,886 | 4.00 | 26,427 |
0.90 | 13,282 | 2.00 | 20,318 | 4.25 | 26,961 |
1.00 | 14,310 | 2.20 | 21,158 | 4.50 | 27,465 |
1.10 | 15,050 | 2.40 | 21,925 | 4.75 | 27,941 |
1.20 | 15,817 | 2.60 | 22,630 | 5.00 | 28,393 |

1.50 | 17,783 | ||||
(B) Lots on which new construction and/or development activity could cause the amount of impervious surface on the lot to exceed the amounts set forth above shall proceed with the proposed construction and/or development activity only if a variance for the increased impervious surface coverage is granted by the Board of Adjustment in accordance with the procedures set forth in § 153.110(D).
(C) The Board of Adjustment reserves the right to limit impervious surface coverage to prevent the unreasonable diversion of stormwater or surface water onto another property or properties or to the town streets.
(D) The equation which may also be used to calculate maximum impervious coverage (MIC) is: MIC= 8812.5 LN (Acreage), where ‘LN’ is the natural logarithm mathematical function. This may be calculated using Excel, if necessary.
