by the Planning Board within 45 days of final approval by the Planning
Board.
[Amended 5-2-2005] |
F.
|
Plats for recording with the Hancock County
Registry of Deeds must include all items indicated with (+), along
with any other items required by the Register of Deeds, and be sealed
by a Maine-licensed professional recognized by the Register of Deeds.
Additionally, the Planning Board may require that existing site information
for all items indicated with (+) be shown on a plan prepared by an
appropriate Maine-licensed professional.
[Amended 5-2-2005] |
G.
|
Unless otherwise approved by the Planning Board,
the applicant shall submit one copy of the plat or site plan in an
electronic file format approved by the Planning Department in lieu
of one paper copy.
[Added 5-2-2005] |

Nitrate Analysis Formula
| ||
A = (qs x Cs) / [Rrecharge x (Cnitrate – Cb)]
| ||
A = Lot size (acres per dwelling).
| ||
qs = Average septic discharge
rate = 270 gpd/dwelling = 0.19 gpm/dwelling (if more than three bedrooms
per dwelling, use the design flows for single-family dwellings provided
by the Maine Department of Health and Human Services in the Maine
Subsurface Waste Water Disposal Rules, 10-144 CMR 241).
| ||
Cs = Assumed concentration
of nitrate-nitrogen reaching the water table from septic discharge
= 40 mg/l.
| ||
Cnitrate = Limiting concentration
of nitrate-nitrogen in groundwater = 5 mg/l (equal to half the EPA
primary drinking water standard).
| ||
Cb = Background concentration
of nitrate-nitrogen in the ambient groundwater (if not known, assume
= 0.25 mg/l)
| ||
Rrecharge = Rate of natural
groundwater recharge, averaged over the year in gpm/acre; some representative
numbers, based on soil types and Bar Harbor average annual precipitation,
are:

2 Glaciomarine clay-silt
soils are not only limiting in their ability to treat residential
wastewater, but they also have limitations relating to other site
engineering issues such as slope stability, drainage, and siltation
potential.

NOTES:
As an example, adjacent to a great pond, if
a twenty-five-foot by twenty-five-foot plot contains five trees between
two and four inches in diameter, four trees between four and 12 inches
in diameter, and two trees over 12 inches in diameter, the rating
score is: (5 x 1) + (4 x 2) + (2 x 4) = 21 points. The twenty-five-foot
by twenty-five-foot plot contains trees worth 21 points.
Trees totaling nine points (21 - 12 = 9) may
be removed from the plot provided that no cleared openings are created.

If there is more than one dwelling unit on a lot, as a result
of the provisions in this subsection or the multiple dwelling units
subsection, the lot is not eligible for any additional increases in
density, except as allowed in the district.
