Site Plan Review
NOTES: | |
A. | Minor site plan submissions. Minor site plan applications shall show all information listed in this section as pertinent to the proposed site plan. The Planning Department, in the pre-application meeting, shall determine these items. |
B. | The scope of the Planning Department's review in considering a proposed revision to a previously approved subdivision or site plan shall be limited to those portions of the plan that have been changed. |
C. | All information on each map, plat or plan shall be easily legible. Each map, plat or plan shall be no larger than 24 inches by 36 inches with a two-inch margin outside the border line on the left side for binding and a one-inch margin outside the border lines on the remaining sides. |
D. | Except as otherwise provided herein, all maps, plats and plans shall be drawn to a scale of not more than 40 feet to the inch. |
E. | For subdivisions, those items above indicated with (*) shall be included on each of two reproducible stable-based transparent originals (one to be recorded at the Hancock County Registry of Deeds and one to be file in the Planning Department) and three paper copies of a plat, which plat shall be drawn to a scale of not more than 100 feet to the inch. Final versions of the two reproducible stable-based transparent originals must be submitted for endorsement by the Planning Board within 45 days of final approval by the Planning Board. |
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. |
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. |
H. | For those items marked with (♦), all wetland boundaries must be delineated using the methods described in the “Corps of Engineers Wetlands Delineation Manual” as most recently amended and published. |

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: | |
Soil Type | Recharge (as % of precipitation1) | Recharge Rate (gpm/acre) |
|---|---|---|
Glaciomarine clay-silt2 | 5% | 0.14 |
Thick silty clay | 10% | 0.28 |
Thin silty till over rock | 15% | 0.43 |
Sandy glacial till | 25% | 0.71 |
Glaciomarine fine sands | 40% | 1.14 |
Raised beach deposits | 50% | 1.42 |
Sand and gravel | 50% | 1.42 |
*NOTES: |
|---|
1 Average annual precipitation in Bar Harbor equals 55 inches/year (USGS, 2002). |
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. | ||
[d] | 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. |
