The following is a summary regarding information <br /> on each of the wetlands and the associated requirements to be in compliance with the city of <br /> Orono's wetland protection ordinance. <br /> Wetland#1 (North end of the property): <br /> According to the city's wetland classification system,wetland#1 has been classified as a <br /> preserve wetland which requires a 50'upland buffer. <br /> Review of the submitted building plans has indicated that wetland#1 and its upland buffer <br /> should not be disturbed due to the construction that will occur on the properry. However, <br /> wetland#1's upland buffer does contain undesirable plant species,details are given below: <br /> A site evaluation was completed on 231u1y 2007 to determine the condition of the vegetation <br /> in the existing upland buffer.A large amount of buckthorn(includes mature plants as well as <br /> seedlings)was documented in the buffer of the wetland during this site evaluation. According <br /> to Division 3 sec.78-1605(2)buckthorn is considered to be an undesirable plant species and <br /> should be removed from the upland buffer area. After buckthorn is removed,bare or disturbed <br /> areas in the understory should be seeded with a shade tolerant,approved native seed mix(see <br /> general comments below). <br /> Low densities of garlic mustard were also found to be growing in the upland buffer of wetland <br /> #1. This is also an unacceptable plant species and should be removed. Once garlic mustard has <br /> been removed bare areas should be seeded with an approved native seed mix(see general <br /> comments below). <br /> Wetland#2(south end of the property): <br /> Wetland#2 has also been classified as a preserve wetland and will require a 50'buffer. <br /> According to the submitted building plan,the patio slab of the proposed pool will be placed in <br /> wetland#2's building setback. According to the city's wetland protection ordinance,Div.5 Sec <br /> 78-1608 2a—patio slabs may be placed in the setback area. The pool slab placement is <br /> acceptable. <br />
