Box 196650 Anchorage, AK 99519 REFERENCE: Subdivision of Fire Lake Heights Lot 1 (Proposed lot lA and lot 1 B; Fire Lake Heights Subdivision Water availability analysis At the present time, Lot 1 is connected to the Carol Creek Water System PWSID# 213247, a Class 'C' water system, which was constructed in ~976 and has been in use ever since. Currently the ADEC does not regulate Class 'C' water systems. However they have indicated that this water system was originally intended to serve 9 lots. I believe at the Present time, only 4 lots are still connected to the community system. Lots 2 and 5 have since drilled wells. The owner of Lot 1 intends to drill separate wells for Lot 1 A and Lot 1 B. These wells will be drilled with the upgrade of the septic system on Lot lA and the installation ora new septic system on Lot 1 B. At that time, Lot lA will be disc0~mected form the community water system. Based upon the attached well logs, it is my opinion that water will be available through the drilling of wells. The new well drilled on Lot 2 is 116 feet deep and provides 10 gpm plus. The well drilled on lot 5 is 200 feet deep and produces of these lots were originally on the community system. i~fformation, please contact me. P.E. 15861 S.

Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Attention: Dan Roth Ref: Subdivision of Fire Lake Heights, Lot 1 (Proposed Lots lA and lB, Fire Lake Heights Subdivision) Mr. Roth: The homeowner is proposing to subdivide the referenced property. We were retained to provide engineering services to meet the platting requirements for on-site water and wastewater system. There is an existing 3 bedroom house that is served by a community water system and an undocumented septic system on the west end of the property (Proposed Lot lA). In order to meet the subdivision requirements we have do a septic system design to include the installation ora 1000 gallon septic tank and a 5-wide trench type drainfield. We have also shown a 10,000sq.~ reserve area for each lot. Attached is a site plan and design drawings which shows reserve areas for both properties. Two test holes were excavated on each property. The dminfield and reserve sites will be designed around the 30 foot radii of these test holes. Attached are the soil logs. Also, attached is a topography site plan which shows there are no slope concerns. If you have any qu ~~' rely, adverse impacts this installation would have on adjacent wells or septic systems. tions, please contact us at 337-6179. Thank you for your assistance. 3701 E.
