Block 1. Valhalla Subdivision Filter Pod to Well Encroachment Waiver Dear Onsite Services Engineer: The existing AX -20 Filter Pod serving the Advantex Treatment System on Lot 1, Block 1, Valhalla Subdivision was apparently relocated at some time in the past after it was found floating in the groundwater. Unfortunately it was relocated only 86' from the well on Lot 1 and 88' from the well on Lot 2. A waiver is therefore required to allow the pod to remain in its current location. Advantex Treatment Systems have been proven to reduce the nitrate content in the septic effluent prior to discharge into the surrounding environment. A recent water sample taken from water in the well indicates only 3.27 milligrams per liter of nitrate/nitrite content. No contamination of the well can be attributed to the current location of the pod. Underlying soils on both lots are dense tight silt (ML) with extremely slow percolation rates. Recent tests indicate impermeable layers of clay are present between the aquifer and the surface soil layers. The well on Lot 1 is 58' deep with casing the entire depth. The aquifer is at 47' below the surface. The well on Lot 2 is also 58' deep. We are confident based on the long term performance of the existing septic system and the water quality from the well that contamination from the existing filter pod is not likely. We therefore recommend that the waiver allowing the pod to remain in its current location at 86' from the well on Lot 1 and 88' from the well on Lot 2 be granted.

A waiver is therefore necessary to construct the absorption bed at this location. This system has an Advantex Treatment System and placing the new bed within 6' of the north lot line will not present conflicts to the lot to the north. A lot line waiver has been in existence for the previous bed for several years. We therefore recommend a waiver be issued allowing the bed to be within 6' of the north lot line. Sincerely, Michael E.

The bed currently is influenced by runoff during the spring and fall of the year. Drainage patterns in the area were modified drastically with the upgrade of Huffman Road several years ago. We are therefore requesting a permit be issued for a septic system upgrade to reconstruct the bed in its current location. The existing Advantex Treatment System will remain in use and be connected to the new bed. The location of the absorption bed is shown on the attached Site Plan. Drainage patterns are also shown on the plan and will be modified somewhat as a result of the proposed construction. The total height new bed will be approximately 4.5' above the existing ground. The test holes placed on this lot revealed silt with some sand and gravel. The percolation rate in the materials encountered was between 60 and 80 minutes per inch. Groundwater was found at 3' below the surface at its highest elevation. Our design provides for the bottom of the absorption bed to be at lest 5' above the highest recorded groundwater elevation. The absorption bed will be 2 - 35' long x 13' wide beds for a total of 900 square feet of absorption area. The distribution line in the beds will be placed at 2' above the existing ground. 2' of fill and 2" of insulation will be placed above the beds to meet Municipal Code and prevent freezing. The side slopes of the mound will be at 3:1 at the north and south ends and 3:1 on the east and west sides. Landscaping and fill will be required to insure positive drainage away from the finished mound. The existing bed will remain in place as no organic mat is present and it is dry for much of the year. All organic material above the bed and approximately 2' of cover over the bed will be removed and replaced with coarse sand and gravel. The ground surface of the lot slopes to the west at a slight grade. The bed will be Lot 1, Block 1, Valhalla Subdivision June 27, 2012 Page Two constructed parallel with the contours of the slope as much as possible. All components of the new septic system will be constructed a minimum of 100' from any surface water and 100' from the well proposed for this lot. No conflicts exist between the proposed well and septic system and those 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. 2. 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. 3. 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. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sinc1erely, p Michael E. Anderson, P.E.

SUBJECT: Lot 1, Block 1, Valhalla Subdivision Septic System As -Built Certificate of Health Authority Approval In early November we checked the water level in Test Hole No. 4 and found it to be 9' below the surface. The sub drain placed earlier in the summer has been very effective in lowering the ground water level on the lot. I then called Dan Roth and advised him of the water level and requested that we be allowed to lower the absorption bed to 3.5' below the ground surface. This elevation provides a minimum of 5.5' separation distance between the bottom of the bed and the water level. Dan agreed this would be acceptable and the bed was placed at that level. The configuration of the bed was changed to 20' wide by 45' long to provide a minimum of 900 square feet of absorption area. The design called for 30' wide by 30' long. The configuration was changed because the developer was required to change the location of the driveway to satisfy Building Safety. During construction the bed was widened to 22'.

Application Impacts to Adjacent Properties Dear Onsite Services Engineer: The owner of Lot 1, Block 1, Valhalla Subdivision intends to construct a new three- bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new septic system to serve the home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and alternate site and the parameters used in the design. Also identified on the plans are the location of the existing well on the lot, test holes and the wells and septic systems on the surrounding lots. Drainage arrows and spot elevations are shown indicating the current drainage patterns. The drainage patterns will be maintained after construction. Substantial soils exploration was completed on this lot last year. A well permit was issued for the lot at that time and the well was subsequently placed on the lot. We have placed additional test holes on the lot this year and monitored the water level over the past three months. Recently a sub drain was placed along the eastern lot line and extended along the southern lot line to daylight. Ditching will be developed along the western property line when the lot is further developed to direct the drainage to a culvert crossing Elmore Street. It appears the ground water level has dropped between 2' and 3' since the placement of the sub drain. Most of the organic and original ground layer has been removed in the area of the proposed absorption bed and the water level was recently noted at 3' to 5' below the surface. All of the test holes placed on this and the adjacent Lot 2 indicate tight silty soils with shallow groundwater. The percolation rate varies between 60 and 80 minutes per inch with the water table now at 3' to 5' below the surface. We are proposing to place a 1,500 -gallon Advantex Treatment System with an add on lift station on the lot. Effluent will be pumped to a 20' wide by 24' long raised mound at the northeast corner of the lot for disposal. The bottom of the absorption bed will be constructed 2' above original ground to insure 4' separation from groundwater. This system will be nearly identical to the system placed last year on the adjacent lot, but slightly larger and higher above Lot 1, Block 1, Valhalla • June 5, 2003 Page Two existing ground. Test Hole No. 4, placed last year is nearest the location of the proposed absorption bed. This hole is now showing 3' of unsaturated soil after placement of the sub drain. The percolation rate of the underlying material was determined at 80 minutes per inch. We have designed the absorption bed based on this data for an application rate of 1 gallon per day per square foot. Coarse sand will be utilized to level the original ground and raise the bed to provide 4' of separation from the groundwater level. The ground surface on the lot slopes as shown on the site plan from east to west at gradual slopes. The absorption bed will be constructed at parallel with the slope as much at the front of the property in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 100' from any surface water and 100' from the well on this and adjacent lots. If the system is constructed in accordance with our design the following statements apply: 1. 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. 2. 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. 3. 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., 4. 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, P4"&",L E a,� � Michael E.
