Project site restrictions and design criteria: 1. Setback. Where there are wetlands along or around a stream or waterbody, the project shall Include and maintain a nondisturbance setback, measured horizontally from the ordinary high water mark, as specified in Table 4. For previously unplatted residential subdivisions, the setback area shall be traded out, rather than being included In individual lots. Projects on sites requiring setbacks shall include a permanent fence, either split -rail or other, to serve as a physical barrier that maintains the integrity of the nondisturbance setback. This fence shall be placed on the proposed new fill, outside of the setback. Both the setback area and the fence shall be clearly depicted on the proposed plans submitted with the GP application. Notes: a. Applicants should contact Municipal Planning or Corps Regulatory staff to obtain or confirm delineation of the setback; b. For currently unmapped streams and drainageways, the GPs will allow road, driveway and/or uti ily crossings of the waterway and/or the setback area, so long as there are no other practicable alternative mutes. 2. Construction Timing Window. To protect nesting migratory birds, as required by the Migratory Bird Treaty Act, no work (.e., clearing, grading, excavation, stockpiling, or placing of fill) may occur on the site between April 15 and July 15, unless: a) the site is sufficiently disturbed prior to April 15 to eliminate suitable nesting habitat; and, b) construction activity will occur continuously through June 15. Note: Clearing or other disturbance ofthe site prior to April 15 may require Corps or other authorization. 3. Surface Water Features. The project shall incorporate design features and construction methods to maintain flow of surface water across the site. To accommodate this requirement, the applicant shall assess the project she to Identify drainage patterns and previously unmapped surface conveyances, such as streams and drainageways. These features must be field verified by Corps Regulatory, or Municipal Planning or Watershed Management staff. The applicant shall contact the Office of Management and Permitting (tet.269-8690), Alaska Department of Natural Resources, if the proposed project will cross any surface flowing waterway. Surface flow features shall be clearly depicted, along with any appropriate setback(s), on the proposed plans submitted with the GP application, as shall the measures proposed to maintain such flows. Cross -drainage, may be directed around the development area, but the project must maintain downstream flows similar in quality, quantity and direction to the pre -project condition. As discussed under Setbacks, the GPs may allow crossings of unmapped waterways, but do not authorize permanent diversions, channelization, or other alteration. 4. Local Flooding. The project shall incorporate design and construction features/methods necessary to ensure that the proposed project will not cause flooding of adjacent properties or public infrastructure. 5. Dewatering of Adjacent Wetlands. The project must incorporate design and construction measures (e.g., trench blocks, impermeable subsurface membranes) necessary to ensure that it will not cause short- or long-term dewatering of wetlands outside the project footprinL Details of the proposed design features and construction methods, along with supporting documentation, shall be included in the GP application. 6. Stormwater Functions. The applicant shall demonstrate that the project plans include sufficient measures to effectively replace the she's pre -project stormwater retention and filtration capacity. The measures shall be sufficient to approximate zero net runoff increase for storms with 2 -year frequency and no more than two times net runoff increase for storms with a 10 -year frequency, including flows from subdrains. Verification that the project's storrmwater design meets this criterion must be obtained from the Municipal Wetland Management Section or its designee, and must be included with the GP application package.

SUBJECT: Lot 2A, Block 2V, Rabbit Creek View Revised Septic System Site Plan Attached is the wetlands permit issued for the subject lot allowing placement of the new septic system. We have also revised the system design due to the presence of groundwater at 4' below the surface. The new system will be a raised bed with a pressurized distribution system. Details of the new design are included for your review. We have inspected the area immediately south of the new absorption system and have not seen surface water over the past year. There is evidence of drainage ditches in the area, but no surface water has been detected. Residents of the neighboring properties state that drainage patterns have been altered over the past several years and surface flow no longer occurs within 100' of the proposed absorption area.

The only possible location for the absorption bed is within 32' of surface water. We are proposing to place a Category III septic system on the lot. The details are attached along with a request for a waiver allowing the bed to be placed less than 100' from surface water. ANDERSON ENGINEERING P.M BOX 240773 ANCHORAGE,. AK 99524 July 17, 2008 Municipality of Anchorage . Development Services Department On -Site Water and Wastewater Program 4700 Bragaw Street P.O. Box 196650 Anchorage, AK 99519-6650 Attention: On Site Services Engineer Subject: Lot 2A, Block 2V, Rabbit Creek View Subdivision Separation Distance Waiver Septic System to Surface Water Dear On Site Services Engineer: Surface area available on the subject lot for placement of a septic system is severely limited by the presence of peat and other unsuitable soils and surface water in many other locations. Some free surface water has been noted approximately 19' south of the south property line and 32' south of the edge of the proposed absorption bed. A waiver is therefore necessary to allow the new septic system to be constructed within 100' of this surface water. Much of the lot and the area to the south have been categorized as Class C Wetlands. A wetlands permit has been issued by the City for this lot for the placement of a house, well and septic system. Unfortunately this is only possible if a waiver is issued allowing placement of the absorption bed less than 100' from seasonal surface water found to the south. We are proposing to place a Category III Septic Treatment System on the lot which is very effective in the treatment of effluent. In addition, the percolation rate in the area of the absorption bed is less than 5 minutes per inch and all water released from the treatment system will be absorbed into the underlying porous soil and will not migrate to the south. The current ground surface slope is to the north and away from the minor surface water to the south. Lot 2A, Block 2V, Rabbit Creek View Subdivision July 17, 2008 Page Two The vegetation on the existing ground to the south side of the absorption bed is composed of brush and grass. The underlying soil absorbs much of the surface water found after heavy rains and during periods of breakup and other heavy runoff events. During the drier months of the year and through the winter very little surface water has been noted in this area. We therefore recommend the waiver be issued allowing the separation distance from the septic system to the surface water be reduced to 32'. Sincerely, /� /] �] %Y ��,..Gl.n_,ki F- a d" J Michael E.
