Hickory Shores is located on the south side of Highway 13, to the west and in- between Crystal Lake and Rice Lake. We were requested by the City to review the constructed retaining walls on the development site and provide comments regarding the condition of the existing construction, and recommendations for remedial construction. Soil borings were performed behind selected retaining walls to determine the soil properties of wall backfill. • We were informed that initial site grading began in June of 2006 by Ryan Contracting for Tollefson Development, Inc. The northern portion of the site (Phase 1) includes completed streets and a few houses that have been constructed. The southern portion of the site (Phase 2) is only rough graded. Utilities have not been installed in Phase 2. It is our understanding that the building pads and streets were rough graded as the retaining walls were constructed. Grade was held down in building pad and street areas to allow for the proposed construction. This included approximately a 2 hold down in street areas to allow for placement of a sand, aggregate base, and pavement section. The retaining walls on the site included both modular block wall and boulder wall construction. The modular block was supplied by Rockwood and constructed at the site by Roste Construction. The boulder walls are noted on the soil boring location plan. The retaining walls were constructed originally in the Summer of 2006. Wall #1 has subsequently been repaired including the installation of a drain pipe. John Oliver and Associates (JOA) was the original civil engineer for the project. Through conversations with JOA we were informed that the retaining walls were designed by another firm. We have not been provided with design drawings for the retaining walls as of this report date. It is our understanding that currently the property is in foreclosure and bank owned. Stork Twin City Testing Corporation is an operating unit of Stork Materials Technology B.V., Amsterdam, The Netherlands, which is a member of the Stork group STO R Stork Twin City Testing Corporation Materials Technology Retaining Wall Review — Hickory Shores Development Page 2 of 6 City of Prior Lake Stork Twin City Testing Corporation Project #3108968 Observations and Soil Boring Testing We reviewed the site with the City on September 15 and subsequently performed additional site reviews and soil borings on September 21 and 22, 2009. The site is surrounded by thick tree cover with Crystal Lake to the north and Rice Lake to the south of the development. The housing areas are vacant, covered only with pockets of small vegetation in portions of southern end of the site (Phase 2). The unpaved subcut street areas in Phase 2 were collecting water, with ponding occurring in low areas where heavier clay soils are present. Erosion was observed in several areas due to the lack of established vegetation and proper finished grades. In areas where more granular soils were present, washouts were observed. Tension cracks were observed at the surface behind Wall 1. Several retaining wall blocks at Wall #1 and Wall #2 were displaced over the wall most likely by vandals. Vegetation was observed growing out of the retaining walls at several locations. A tree had fallen over on Wall #3 (see attached photograph). Settlement was observed directly behind the retaining walls at several locations. Aggregate was observed filling the block cells at all block retaining wall locations. In general, one to three inches of aggregate was observed directly behind the back face of the wall. However, minimal aggregate was observed behind the back face of the wall at some locations. Drain -tile was observed extending through the retaining walls, however, at most locations the drain -tile outlet was dry while portions of the wall were wet. This may be due to portions of the drain -tile system being clogged with soil, or that the site clayey soil is preventing water from getting to the drain -tile and permeating through the block. Calcium deposits were observed on the face of Wall #4. This indicates moisture has been present for a period of time and subsequently left behind the calcium deposits when dried. We performed five soil borings on the site on September 21 and 22, 2009. The soil borings were performed with an all- terrain drill rig using a 2.5" inch diameter spilt spoon sampler being pounded continuously with a 140 pound hammer. The number of blows per 6" was recorded and soil samples were collected for soil classification purposes. The borings were located behind selected retaining walls to determine soil properties of the backfill used during retaining wall construction. The soil profile depicted by the borings showed layers of sandy lean clay, clayey sand, and lean clay with sand. Lenses of clayey sand and sand were also present within soil layers as shown on the boring logs. Groundwater was not encountered within the bore holes at the time of drilling. Since the clay soils encountered in borings are relatively impervious or slow draining, it may take several days for groundwater in a borehole to rise to its hydrostatic level. If more accurate water level determinations are required, piezometers should be installed and the water level monitored over a period of time. STO R K Stork Twin City Testing Corporation Materials Technology Retaining Wall Review — Hickory Shores Development Page 3 of 6 City of Prior Lake Stork Twin City Testing Corporation Project #3108968 The density of the fill soil behind the retaining walls varied somewhat at the different soil boring locations. The fill at boring location B1 (Wall #1) was very soft as determined by the penetration values (N- value) obtained during drilling. Very soft soil layers were also encountered near the surface of borings B3 (Wail #2) and B4 (Wall #3). Soft to firm soil layers were encountered in lower portions of the fill of borings B2, B3, B4, and B5. Firm soil layers were present beneath the fill at all boring locations. This included the soil supporting the bottom of the retaining walls. The boring location plan and soil borings are attached to this report for your information. The approximate bottom of the retaining wall is noted in the remarks column on the boring Togs. Two test holes were excavated with a shovel by hand behind Wall 1 to verify geo -grid placement. Geo -grid was present at both locations, however, settlement was observed within the geo -grid soil profile. The settlement observed was approximately 4 to 5 inches. The front faces of the retaining walls revealed that geo -grid was used for wall construction. Geo -grid was typically placed every two feet of wall height, typical for retaining wall construction. Pictures were taken to document retaining wall and soil conditions and are attached to this report. It should also be noted that two retaining walls as shown on the original grading plan were not constructed at the time of our review. These retaining walls are noted on the soil boring location plan. Engineering Review and Recommendations In our opinion, the soil conditions beneath the bottom of retaining walls appeared suitable for support of the walls. Typically, walls of this size and height require a soil bearing pressure of 3000 pounds per square foot. In our opinion, the soils depicted by the borings at bottom of retaining wall elevation met or exceeded this criteria. The soil used as wall backfill was comprised mainly of sandy lean clay, clayey sand, or lean clay with sand. Sand lenses were also present within the soil profile. These soil types were most likely the native soil encountered at the site during construction. These soil types typically do not provide for good drainage due to the plastic nature of the soil. Also, due to the lenses of sand within the backfill, additional water infiltration through these sand lenses can occur causing additional lateral earth pressure to build up behind the retaining wall. The density of the backfill soil behind the retaining walls varied considerably. Very soft soils were encountered behind Wall #1 (B1) and near the surface of B3 (Wall #2) and B4 (Wall #3A). Soil compaction tests were performed at the site by Braun Intertec Corporation, during the original site grading. We were provided a copy of the soil compaction test results by the City. Thirteen (13) soil compaction tests were performed in retaining wall backfill STO R K ` Stork Twin City Testing Corporation Materials Technology Retaining Wall Review — Hickory Shores Development Page 4 of 6 City of Prior Lake Stork Twin City Testing Corporation Project #3108968 areas between August 10 and August 30, 2006. The soil compaction test results ranged from 88% to 104% of the Standard Proctor density. Two of the compaction tests for Wall #1 failed to meet the minimum compaction requirement of 95% according to the test results. The moisture content of the soil at the time of the compaction tests ranged from 9% to 17 %. Substandard and uneven compaction of retaining wall backfill may cause post construction soil settlement and issues with the geo -grid supporting system. The soil settlement can misalign the geo -grid and, as a result, variable earth pressure forces can act against the retaining walls causing alignment issues with the wall or bulging within portions of the wall. Again, excessive settlement was observed behind retaining Wall #1 and this is most likely from poor compaction during construction and water being allowed to pond behind the wall. Minor settlements behind the wall were observed at other retaining wall locations. Water ponding in street areas adjacent to retaining walls can cause additional surcharging and lateral earth pressure against the retaining wall. The ponding water also can infiltrate into sand lenses and become perched behind the wall system causing additional water pressure to build up behind the wall. The water observed ponding near Wall #1 is of immediate concern and should be addressed. Site grading should be performed to divert water away from the retaining walls or a properly constructed spill way over the wall should be constructed to aid site drainage until the development is completed. Attempts at a spill way approach were made except the contractor left the road at the original hold down elevation which was approximately 2W below surrounding grades. Improper grading caused water to pond in the street and infiltrate the wall system causing excessive hydrostatic pressure against the wall. It is our opinion that this needs to be corrected immediately or failure of Wall #1 may occur. Portions of Wall #1 may need to be reconstructed and the backfill soils behind the wall re- compacted to proper design specifications. Aggregate was observed within the block wall system as noted above and shown on the attached photographs. Typically, for walls of this length and height with clayey soil used as backfill, additional aggregate would be placed behind the walls to act as a drainage blanket. If retaining walls are reconstructed we recommend this aggregate drainage blanket should be installed up to 1' thick behind the back face of the retaining wall block with appropriate drain -tile to drain the aggregate. The boulder walls were reviewed and appeared to be in relatively good condition. Some minor pockets of erosion around the walls were observed but did not appear to affect the wall performance. Seeding should take place in areas were grasses have not been established. We would recommend additional review be performed in the Spring of 2010 to verify runoff from snow melt has not damaged these wall systems. STORK' Stork Twin City Testing Corporation Materials Technology Retaining Wall Review — Hickory Shores Development Page 5 of 6 City of Prior Lake Stork Twin City Testing Corporation Project #3108968 Fill should be placed and compacted behind the retaining walls in areas where settlement has taken place. Additional compaction should be performed with small plate or turtle type compaction equipment to not cause further damage to the retaining walls but aid in sealing up the surface, minimizing water infiltration behind the wall. If the southern end of the site (Phase 2) remains undeveloped, then we recommend some site grading be performed to aid surface drainage. Seeding should also be performed in non - vegetated areas to help minimize erosion. The project civil engineer should be contacted to aid with developing a corrective plan for handing site drainage with the emphasis on protecting the retaining walls while the rest of the site is undeveloped. We have listed below some of the remedial repairs that should be performed to protect and maintain the existing construction. 1. Retaining wall capping stone that has been removed should be replaced at all locations. The capping stone aids in preventing moisture from rain events directing penetrating the wall system. 2. As a safety precaution, the orange construction fence in -place in front of the retaining walls should be reconstructed in areas where the fence has been displaced. 3. The tree that has collapsed on Wall #3 should be removed carefully as to not further damage the wall. The block wall where the tree fell should be repaired. 4. Voids at the surface of the retaining wall block (Wall 3) should be fill with aggregate and capped with cohesive soil to further minimize water infiltration into the wall system. 5. The original retaining wall design plans should be obtained and reviewed to determine that wall construction has been performed per the design document. This would include the placement of the geo -grid, draintile and aggregate thickness behind the wall. 6. The retaining wall contractor should be contacted to review existing site conditions and provide additional recommendations as to maintaining the retaining walls prior to the development being completed. We recommend additional monitoring of the retaining walls be performed periodically to determine if additional corrective action or repair is needed. This monitoring should continue until, at a minimum, final site grading and street improvements are in place.

Using this procedure, a 2" O.D. split barrel sampler is driven into the soil by a 140 pound weight falling 30 ". After an initial set of 6 ", the number of blows required to drive the sampler an additional 12" is known as the penetration resistance, or N value. The N value is an index of the relative density of cohesionless soils and the consistency of cohesive soils. Thin wall tube samples were obtained according to ASTM D 1587 -00 where indicated by the appropriate symbol on the boring logs. Rock core samples, if taken, were obtained by rotary drilling in accordance with ASTM D 2113 -06. Power auger borings, if performed, were done in general accordance with ASTM D 1452 -00. Soil Classification As the samples were obtained in the field, they were visually and manually classified by the crew chief in accordance with ASTM D 2488 -06. Representative portions of the samples were then returned to the laboratory for further examination and for verification of the field classification. Logs of the borings indicating the depth and identification of the various strata, the N value, the laboratory test data, water level information and pertinent information regarding the method of maintaining and advancing the drill holes are attached. The descriptive terminology and symbols used on the boring logs are also attached.

In accordance with your request, Mortarless Systems Engineering (MSE) has prepared a design and analysis of the segmental retaining wall (SRW's) proposed for the Industrial Park Rehab project in Mendota Heights, Minnestoa. Based upon our retaining wall analyses, it is MSE's opinion that the subject proposed SRW will be internally and externally stable provided the specific recommendations contained herein this report, and the general construction recommendations of Rockwood's Concrete Segmental Retaining Wall System specifications, are incorporated in the construction of the subject SRW's. Internal drainage systems, other than the drainage rock, are not required. However, if conditions are exposed during the course of construction, such as seepage in the backcut, additional drainage systems may be required. MSE has not evaluated the global stability of the subject SRW's. MSE recommends that the p t soils - • analyze the subject SRW's for global stability. u M nr , i�f gu ..

In accordance with your request, Mortarless Systems Engineering (MSE) has prepared a design and analysis of the segmental retaining wall (SRW's) proposed for the Industrial Park Rehab project in Mendota Heights, Minnesota. Based upon our retaining wall analyses, it is MSE's opinion that the subject proposed SRW will be internally and externally stable provided the specific recommendations contained herein this report, and the general construction recommendations of Rockwood's Concrete Segmental Retaining Wall System specifications, are incorporated in the construction of the subject SRW's. Internal drainage systems, other than the drainage rock, are not required. However, if conditions are exposed during the course of construction, such as seepage in the backcut, additional drainage systems may be required. MSE has not evaluated the global stability of the subject SRW's. MSE recommends that the : oject soils - q gineer analyze the subject SRW's for global stability. 1 APPROVED `av ENGINEERING DEPT Mi. .r.nt, :II 1835 Sign Enclosed: Rockwood's Concrete Segmental Retaining Wall System Wall Calculations Wall Profiles Copy: (4) Addressee APPROVED (1) Engineering Department PLANNING DEPT SignedAg Date 325 Alliance Place NE, Rochester, MN 55906 -3975 • phone 507.529.2871 tax 507.529.2879 e-mail info®mortarless.net • PRIOR LAKE DEPARTMENT OF BUILDING AND INSPECTION INSPECTION ECORD SITE ADDRESS '?) / /N 1 �'' Jun; .
