BOX 3-4016 ' ANCHORAGE, ALASKA ' 99501 MUnicipality of Anchorage MEMORANDUM DATE: September 17, 1985 TO: FROM: Susan Oswalt ~ SUBJECT: Proposed Christopher Hts. #1, S-7974 On September 12, 1985, I made an inspection of the above proposed subdivision with Steve Eng, District Engineer with Alaska DEC. The following observations were made: 1. The culvert at the intersection of Alatna and Rockridge (Regina) is filled with mud at both ends. me The ditch on the west side of Rockridge has running water from Alatna to the northern end of the subdivision. On 9-13-85 the flow was gone between Alatna and Rock Circle, but water was springing up just south (upstream) of the culvert at Rock Circle, and being joined by water from the ditch near Lot 3 Block 2. There is a newly constructed house on Lot 3, Block 2. installation for this house was red tagged on 9-13-85. has been revoked. The sewer The permit The catch basin on Lot 3, Block 3 was absorbing water from two well defined flow areas. A thaw pipe was in the culvert. The ditch upstream from the basin was dry. 5. The ditch cut near Lot 2, Block 3, was quite moist and water seeps were observed. e We traced the path of the old streambed which the engineer certified as being removed by the culvert installation. Water was ponding on Lot 1, Block 2 and flow could be detected from the pond towards Ridge Court. On the north side of Ridge Court was a well defined water flow heading along the previously delineated stream path. This flow was traced to its exit on the north side of Lot 2, Block 1. The flow along the ditch on Rockridge flowed through the culvert on Ridge Court and did not appear to be affected by the stream flow at this intersection. ® Water was running in the ditch in front of Lot 1, Block 3. Two ditches had been excavated to drain this lot and were exiting into the ditch. A house pad has been constructed and a well drilled. A footing drain empties into one ditch; into this same ditch empties overland flows as well as reverse flow out of a newly installed on site sewer system. This system is full of water and water flows cross it and ponds on it. The system was red tagged on 9-13-85. The permit has been revoked. September 17, 1985 Christopher Hts. #1 Page 2 There is a continuous, gaining flow of water along the east and north of Rockridge (Regina) from Lot 1, Block 3 to the final culvert and the end of the drain system. This flow runs over the top of the installed solid pipe culvert. 9. The cutbank along Lot 1, Block 1 is seeping and a portion has already eroded. There is a strong sewage smell at this location. 10. There are numerous small rivelets and streams joining the ditch flows along the north portion of Rockridge Drive. These flows con- ver~e below the culvert at the end of the installed solid pipe. A large ponding area exists around the final culvert intake area. Water is collected there and flows through culvert beneath the road to its final convergent flow. Prior to final approval, we will ask for additional testing and water monitoring sites, and the elimination of Lots 1 and 3, Block 3; Lot 2, Block 1; and Lot 1, Block 2. We ask for 100 feet setbacks to both ditches as well as the existing stream, and resolution of the problems with sewer installations on Lot 1, Block 3 and Lot 3, Block 2.
