SUBJECT: Lot 11, Woodhaven Subdivision No. 3 Certificate of On Site System Approval The absorption bed for Lot 11 , Woodhaven Subdivision No. 3 will require substantial grading before it is acceptable. The surface conditions on the site are not suitable to complete the grading at this time. We are therefore requesting a Conditional COSA be issued so the property can be transferred. The grading will be completed no later than June 15, 2017. The grading will have no impact on the operation of the septic system. The surface of the lot is basically flat in the area of the new absorption bed. The configuration of the bed is rotated 90 degrees from the design to allow additional grading and landscaping area in the back yard. Placement of the bed in this configuration does not impact wells or septic systems planned for the subdivision.

Received By: Issued By: Date: S15/I May 25, 2016 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Tract D-lB-A, Woodhaven Subdivision No. 2 Septic System Design and Permit Application Impacts to Adjacent Properties Dear Onsite Services Engineer: Tract D-1B-A of Woodhaven Subdivision No. 2 is currently being subdivided into 13 lots. The owner of the tract intends to construct a four bedroom home on what will eventually be Lot 11. The tract is currently undeveloped so we are requesting a permit be issued for the construction of a new well and septic system for the entire tract to accommodate the home. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. No existing wells or septic systems are within 200' of the proposed systems nor are wells or septic systems proposed for the adjacent lots that will conflict. Drainage contours are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. A test hole was recently placed on the lot in the area of the absorption bed. It indicated the presence of silty gravel with some sand (SM/ML). The percolation rate of the material was determined to be 120 minutes per inch. The characteristics of the underlying soil was found to be similar to the test hole placed dudng the eadier phase of the subdivision project and identified as TH12 on the Site Plan. Groundwater was found during the placement of that test hole at 10' and rose to 4' during the monitoring period which included October 13, 2013. This again was similar to groundwater measurements in the new THA. An application rate of .5 gallons per day per square foot was used in the design of the absorption system. An Advantex Treatment System designed for a four bedroom home will be placed on the lot along with a pump vault. Effluent will be discharged into a 40' long by 30' wide absorption bed. The distribution line in the bed will be placed at .5' above the surface. Existing organic matedal will be removed to 1' below the surface and replaced with coarse sand to the existing ground surface where drainfield rock will be placed. A minimum of 2" of insulation and 2' of fill will be placed over the absorption bed and 4' over the septic tank. Tract D-lB-A, Woodhaven Subdivision No. 2 May 25, 2016 Page Two The ground surface on the lot in the area of the absorption bed slopes at a shallow grade to the west. The new bed will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and any surface water and 10' the proposed and existing water services in the area. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.

ANDERSON CERTIFY THAT THIS WAS PERFORMED IN ACCORDANCE WITH ALL STATE AND MUNICIPLE GUIDELINES IN EFFECT ON THIS DATE: 8/I/16/16 August 1,2016 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Su~e~: Woodhaven #2, Tract D-1B-A Absorption Bed Width Dear Onsite Services Engineer: The area available for a septic system on the subject lot, which is proposed Lot 11 of Woodhaven Subdivision No. 3 is limited by several factors including the presence of groundwater, location of wells on this and surrounding proposed lots and the placement of the house and driveway. An absorption bed must be placed to insure the separation from groundwater can be met. The width of the bed must be 30' to provide the necessary absorption area to meet the design. The ordinance governing septic systems states the bed width can be greater or lesser than 15' with approval from the department. We hereby request that approval. The bed will be accessed with a pressure distribution system. Effluent will therefore be dispensed uniformly over the area. Effluent will be discharged after undergoing treatment through an Advantex Treatment System. A minimum of .5' of drainfield rock will be placed. The bed will be constructed without any ddving or compaction of the bed by equipment or labor. A bed width as noted above and shown on the Site Plan will not adversely affect the operating characteristics of the absorption system. Sincerely, Michael E. Anderson, P.E. ANDERSON ENGINEERING P.O. BOX 240773 ANCHORAGE, AK 99524 522-7773 677,7766 (FAX) August1,2016 Municipality of Anchorage Development Services Department On-Site Water and Wastewater Program 4700 South Bragaw Street Anchorage, AK 99519-6650 Subject: Woodhaven #2, Tract D-1B-A -( Proposed Lot 11 ) Trench Side Slopes Dear Onsite Services Engineer: Absorption system sites on proposed Lot 11, Woodhaven Subdivision No. 3 are limited by the presence of groundwater and tight soils with few areas acceptable for the placement of an absorption bed. The most suitable area to place the new bed is approximately 8' from the 10' easement parallel to the southern lot line. The total height of the fill for the absorption bed will be approximately 3' above existing ground. The 3:1 side slope will encroach onto the easement. We therefore request a waiver allowing the slope to be 2:1. The slope will be covered with topsoil and seeded with grass. Maintenance will be provided until a flourishing stand of grass is achieved. The 2:1 slope is standard for fill slope requirements in the Municipality. No erosion of the slope is anticipated once revegetation is complete. Sincerely, Michael E.
