Tigard, OR 97223 Dear Ms. Prichard, In answer tp tl.e questions tri your letter of August 6, 1: 92. I do not find any records of soil compaction tests or repo-, a from a geotechnical (soils) engineer. The name of the pe�rs,in that inspected the construction of the subdivision is Mr. Carl Vieweg (Engineering Department) . There are numerous comments from the inspector regarding the construction- work (i.e, construction of j curb, storm sewer roadways, etc. . . ) , however, there were none that discuss any problems relating to soils, springs or fill. I€ you wish to review the comments, I would be hapr , to provide them for you. As for a date when the subdivision was appro•red, there isn't one. The final. acceptance of a subdivision does not occur for several years after initial construction (which all.owu for deficiencies in the public improvcments to surface and he corrected. before the city assumes responsibility for maintenance of the development) . I believe the subdivision was approved for issuance of building permits in August or September 1.990, If you have any further_ questions, please call me at 639-4171. Sincerely Brad Roast Building Official pc: J.T. Roth I 13125 SW Hall Blvd,P.O.Bo.-(23397,Tigard,Oregon 9722.3 (503)639-4171 --- - Marion L . Prichard 12294 S .W.

Robinson, City Attor.evs office RE: City Liability for Damaged Foundation You called and asked me whether the City might be liable for damage to a dwelling's foundation. You told me that there was some evidence in the record of underground springs in the subdivision,. The dwelling's owner has asked the City if it has any liability. The Cita might be liable only if there was a duty to consider the springs when reviewing the subdivision. See Miller v_ Grants Pass Irr_Aation District; 297 Or 312, 686 P2d 32.4 (1984) . Even if there was a duty, if the City reviewed ti.- evidence and approved the subd.'.viLion anyway, this is a discretionary decision. The city is not li2-hl- for negligence in discretionary decision-making. Stevenson v., State__ of Creaon, 2^0 Or 3 , 619 P2d 247 (1980) . Another issue is when the owner_ first had notice and suspected the city. The owner must. give notice within 180 days of notice of damage caused by the City13 acts or the claim is barred. Sells v. Nickerson, 76 Or App 686, 711 P2d 171 (7.985) . The property owner may have a c1dim against the builder or the subdivider, but the City is not liable unless it failed to exercise to exercise a ministerial duty. I suggest that we meet. with Brad Coast to discuss this matter furt'ier. This memorandum is based only on the facts contained herein. MCR/sb tntr\tigard\bewersdorfl.lt 1 4-1 t f 17 0717/— Geotechnical Resource; Incorporated Consulting Engineers, Geologists, and Environmental Scientists , July 28, 1992 1\FINKPT-1.160 Charles and Mary Pritchard 12294 SW Landsdown Lane Tigard, OR 97223 SUBJECT: CONSULTATION REGARDING RISIDENCE AT 12294 LANDSDOV.N LANE, TIGARD, OREGON At your request, G-,otechnical Resources, Ili„ trt?;j h evaluated subsurface drainage and foundation performance at the above-referenced residence. Dwight Hardin, a GRI principal, visited the residence on July 1 and 9, 1992, and met with you. Based on our observations and discussions with you, we understand that your primary concerns are :.;sociated with wet ground conditions beneath and around the house and recently note! cracking of the foundation. We understand that construction of the house was completed in April or May 1?91, and you have occupied the residence for abont 1 year. Site Observations For the purpose of this discussion, we have assumed that the plain, or front, entrance is on the east side of the house, and the fireplace in the family room is on the north side of the house. The garage extends to the southeast from the southeast corner of the house. Our observations are summarized below. 1. The residence is located at the unci of a private roadway ex,ending north from SW Landsdown Lane. The roadway slopes down from south to mirth and the lowest point of the roadway is at the top of the Pritchard's driveway. Basad on a review of street improvement plans for the subdivision prepared in 1990 by Burtc . =:ngineering and Surveying, runoff flows down the pri• ate driveway where it enters two catch basins near the top of the Pritchard's drivc,,vay. 2. The mo-story house is situated on a lot that slopes down from east to west toward a small creek. The miia entrance door is at ahout the same level as the ground surface, the main floor is 7 to 8 ft above the ground surface r.t the west side, or rear, cf the house. 3. The house is supported by continuous wall ibotings and interior isolated pad footings. A craMspace is present beneath all of the house, except the garage which has a concrete slab-on-grade floor. i` �. ► o� P;t� 7412 SW Bea%erton-Hillsdale Hwy � O Suite 102 Portland 0,egon 9722 O L Phone(503)292-2621 J C f ---------� =SAX j503►2�.'•]b96 - ---_ °_-----�- - _'..._...� �__� ? �� � � � �•� — — � _ _ r � :' � 4. Groundwater ser,)s or springs emerge beneath the house. The water ponds and slowly flows to a drain outlet in th( northwest c,2rner of the crawlspace. Most of the seepage appears to emerge in the south and north portions of the crawlspace. Most of the ground surface i•t the crawlspace is wet and muddy, and there are areas where the water forms pu('.,tles. The remnants of water-loving plants were observed beneath the visqueen ground cover. S. WiEn the crawlspace, the ground adjacent to footings was probed with a 'f2-in. diainetec rebar. The bar could easily be pushed by hand to depths of about 8 to !2 in. below the bottom of the wall footing along portions of the north and south walls and at some interior pad footings. The soft soils are generally most prevalent beneath about the west half of the house. 6. Decent shallow cuts near the e4st, west, and south sides of the house expose about a 2-ft thickness of surface silty fill containing varying amounts of wood and vegetation material. The fill appeers to be underlain by natu.ally occurring silt soils. 7. Shallow groundwater was noted in a recent excavation about 40 ft west of the house and in freshly dug post holes along the west portion of the north property line. 8. A few hairline cracks are present in the wall footings and one larger crack is present in each of the south and north wall fo,qinm. The Pritchards indicated that cracks were ; it;ally noticed in April 1992, and new hairline cracks were discovered in July 1992. "I he Pritchards have noted a total of five hairline cracks and two larger cracks. The larger crack in the south wall footing was noted as a hairline crack in April 1992 and is presently about tix in. wide. 9. A crack extends across the garage floor slab from northwest to southeast. The southwest, or rear, side of the slab is relatively level; the northeast side slopes down to the northeast The crack was recently sealed with a filling agent by the contractor. Conclusions and Recommendations Our observations at the site indicate th:tt at least portions of the lot are blanketed with fill containing wood and other organic material. We do not know if fill is present beneath the house or beneath the footings. However, soft, compressible soils are present beneath some of the wall and pad footings. The large cracks in the north and south wall footings are probably the result of settlement due to the underlying soft soils. The appearance of new ct acks during the past few months suggests that settlement is occurring- however, since you have not observed any significant cracking of the interior finished walls, it does not appear that significant differential settlement has occurred tc date. It also appears that the cracking of the garage floor slab may be due to settlement of the northeast portion of the garage floor area. We anticipate that continued significant settlement of the foundation would initially result in the formation of cracks in interior finished walls and around windows and do,)rways. More severe settlement could reo-ire remedial measures such as deepening the footings to firm soil. The ground beneath the house is wet due to springs and seeps. The drain outlet located in the northwest corner of the crawlspace does not effectively drain the crawlspace. Groundwater occurs at shallow depths on the sloping lot. Considering that the winter of 1991-92 was drier than usual and the summer has been relatively dry, i, should be anticipated that seepage could be more severe during years uf normal or above- average rainfall. The roadway base course and utility trenches beneath the roadway may also be directing water toward the house. Our recommendations are summarized below. 1. To evaluate whether settiement ;',e wall footings may be continuing, the footings should be frequently examined for new cracks. Existing cracks should be monitored to determine if the cracks are becoming wider and longer. Procedures for m;nc.4oring the cracks were reviev ed with Mary Pritchard. 2. As recommended by the writer, the ground surface along the south side of the house was recently regraded to droin surface ninoff away from the house. 3. To drain the water in the crawtsnace, we recommend teat subdrains be installed heneath the house to intercept, co lest, and remove the seepage nd spring water. A si,ggested layout and detail for cr..µ,lspace drains are attached. The drain layout is approximate and may need to be modified during; ins,allation. ;. To intercept shallow groundwater moving toward the house, subdrains can be installed along the perimetox of the house. However, a concrete sidewalk, dri✓eway, and parking area are. i,r. ;ent along the front of the house. For this reason, the drains could initially be constructed as sho%tn on the attachment and evaluated. If this layout does not significantly reduce or eliminate the seepage beneath the house, the 1 drains could be extended around the front of the house and garage. However, it 1 should be understood that ev:.n if the drain is extended around the garage and front of the house, it may not completely eliminate the seepage beneath the house. 5. To intercept water that may be flowing toward the !louse through the roadway pavement hale course, we suggest that drain, or weep, holes be made in the catch basins at the granular base course level.

I observed starnding water near the footings along both sides and the rear of the house. I probed these areas with a 3/8" round, pointed probe. The ground was Fof} to a. depth of approximataly 3.0-18". There appears to be some erosion of the dirt under the footings at a couple of locations. I believe the source of this water is probably from springs located in the hillside above the house.
