Shuler inc_ P.O. Box 1207 Davenport,Washington 99122 Atm:Mr. Mike Shuler ADDENDUM NUMBER 4 TO REPORT OF LIMITED SUBSURFACE DRAINAGE STUDY,WOODLAND TERRACE SUBDIVISION,SPOKANE,WASHINGTON Dear Mike, This letter is Addendum Number 4 to my February 19,2001 report,which summarized the results of a limited subsurface drainage study conducted at Woodland Terrace subdivision in Spokane,Washington. The purpose of this addendum is address the drainage of Lot 7 of Block 25 on 16th Avenue_ It is my understanding that Mr. Cliff Mort of Monogram Homes plans to build a house of the Foundation Detail/Type 2 on this lot,and that the finish floor elevation of the daylight basement will be close to the existing ground surface. The lot is located just east of the detention pond at Vacated Lloyd Street,just north of 16th Avenue. I understand that Mr.John Hohman,Spokane County Utilities,is concerned that if the detention pond were to remain full for an extended period,it could cause rising of the groundwater level on Lot 7 and the groundwater could infiltrate into the daylight basement. On May 11,I examined and logged the subsurface conditions in a test pit that your backhoe operator excavated approximately in the center of Lot 7. The test pit,designated TP-550, extended to a depth of 6.0 feet below the ground surface. Using a hand level,I determined that the ground surface at the test pit location is approximately 2.0 feet above the detention pond spillway. A log of the test pit is included as Table 3. The native subsurface conditions exposed in the test pit consisted of gneiss bedrock,decomposed completely to firm to very firm, sandy silty day. No groundwater or soil mottling were encountered in the test pit. In my opinion,based on the relatively impermeable nature of the decomposed gneiss and the Fax : 509-466-4190 May 17 '01 15:30 F.03 00-117 2 elevation of the proposed new house above the spillway,it is very unlikely that water accumulating in the detention pond would have any effect on the daylight basement of the new house. Drainage recommendations presented in my original report of February 19,2001 and subsequent addendum are also appropriate for the proposed new house to be constructed on Lot 7 of Block 25. If you have any questions concerning any of the conclusions and recommendations presented in this addendum, please contact me. ��,,,,,,// �"p1 Sincerely, AT'swogc� 7.11 1-01 JAI4".c 117 ► " +�Jt Grant R Cummings, P.E.,P'.G. • ._ 027212 %,,tsorsToo End: Table 3 1 rJwuatia(}6/a7d Fa:: . 50';-!66--4196 day _ 'C 1 15'3'0 F.(J 00-117 Table 3 Additional Test Pk I ,16th Avdsee May 11,2001 TP-5.50 Ground surface elevation is 2.0 feet above top of detention pond spillway. 0.0-1.0 ft, Loose,gravelly sandy silt FILL;moist. 0.1-6.0 ft.
