ICRNT 2;'TFfI.,i SHITH ISSLEP HENKINS SUBDIVISION 10/9/85 Keith Bandt Platted: Zoned: Lot Description: Problems: Probable Causes: End Effect: September 13, 1955 (Plat #387) R6 in 1982. Previously, it was zoned UNRESTRICTED 61 lots and 3 tracts. Majority of the lots are 20,000 s.f. One of the affected lots is only 14,365 $.f. Water table has increased in recent years causing systems to fail and sewage to leak onto the ground surface. Lots most affected are cross-hatched on Figure 1. Based on soil tests conducted in 1982 on several of these lots, water levels have increased 4-6 feet. System failure in this case can contaminate the shallow water table, and the potential exists for contaminating the deeper drinking water aquifers although no problems have surfaced to date. Due 1. e e to a combination of 3 factors; Natural phenomena - A natural increase in the water table due to changes in the hydrologic cycle. There is historic evidence that the area affected was very wet, saturated by ground water, prior to development. There are presently many indications of saturated soil as evidenced by small streams, springs, and weeps within the affected area. Monitoring well data helped establish the boundaries of the affected area. A stream diversion around lots 8,9, and 10 may be a factor in fixing the water table elevation on Lot 15, Block 3, although the degree of impact is difficult to assess and is not the sole factor. Wastewater loading from septic systems probably aggravates the situation by contributing to the water table rise. Lots 12-15, Block 3 and Lots 5-6, Block 4 will be required to abandon their existing systems and hook up to a holding tank or package treatment plant (innovative) by November 1, 1985. Lots 3-4, Block 4 will be required to raise the absorption field to meet the proper separation distance to ground water. Curtain drain systems are not viable and have been excluded as an option. High fecal coliform levels found in a monitoring well on Lot 3, Block 5 are currently being investigated. The water supply well for this lot is in close proximity and is only drilled to a depth of 44 feet with a static water level of 6 feet from the ground surface. l~:90001.L~ ~OUl S~OA~A~DS ~ 9 ~ SLOq ~309~ NOIStAtdS¢~S SNI>IN3FI L MUNICIPALITY OF ANCHORAGE DEPARTMENT OF HEALTH & HUMAN SERVICES Division of Environmental Services On-Site Services Section P.O.

I.D. # 05129101 Dear Jim, Per our Telecon this date regarding your concern with the apparent existing "gray water" absorption system and it's possible future use. To prevent possible future use of what appears to be a "gray water" absorption system installed by a previous owner, we requested the owner to cut off the suspect pipe below grade, fill the pipe with as much concrete grout as practically possible and regrade the 9round over the pipe. This work has been completed and verified to my satisfaction as stipulated above. BATES ENGINEERING P.O.

I.D. # 05129101 Dear Dan, Per our Telecon this date regarding our resubmittal of the HAA for the subject property we'd like to clarify the well casing depth and provide some additional information on the holding tank. WELL The well casing was verified to a depth of 28' and appeared to extend to approximately 40'. HOLDING TANK The last verifiable date of pumping prior to 2/21/96 was 11/4/95, so we inspected the drain system under the building; a 2" line and a 4" went into the ground and appeared to probably tied together on the way to the holding tank. However, tracing the 2" line back to the floor we found where it appears that the drain pipe for the "gray water" had been rerouted inside a wall from tying into the 4" commode drain to probably a "gray water" absorption system by a previous owner. The owner has rerouted the 2" collection pipe back to the original system which will eliminate what we assume is a "gray water" absorption system. BATES ENGINEERING P.O.

I.D. # 05129101 Dear Dan, Per our Telecon, the following is a summary of inspection and testing to clarify concerns for the HAA approval for the subject property. WELL The well casing depth was verified to an approximate depth of 40'. HOLDING TANK The holding tank was pumped and tested for infiltration and then filled with water to above the existing alarm setting and tested for exfiltration without any detectable leaks. Calculations showed that there was approximately 225 gallons of storage above the existing alarm. A new float sensor was installed to the proper level to provide for current (since 1986) storage requirements of 450 gallons.
