PROJECT DESCRIPTION L01 -039 - Shoreline Permit October 8, 2001 The project is to re- grade, fill and pave an existing access area on the east side at the rear of buildings 734 and 741 in Segale Business Park. The area to be paved is 1.3 acres, and a total of approximately 4,000 cubic yards of material will be placed for filling and paving. The surface is currently crushed rock. The existing storm drainage will be repaired and upgraded and will continue to collect storm water and direct it into the existing storm drainage system. The upgrade includes a new oil /water separator. The pavement area is within 200 feet of the Green/Duwamish River and the proposed project is subject to Shoreline Substantial Development permit. The original scope of work included planting new trees adjacent to the existing levee. However due to safety concerns expressed by King County and Army Corps of Engineers, the project was revised to eliminate any landscaping in the vicinity of the levee. II. FINDINGS The site is within the jurisdiction of the Tukwila Shoreline Management Program (SMP). This program was adopted in June, 1974 and amended on March 16, 1982. The City's SMP was reviewed and approved by the State Department of Ecology as being consistent with the State Shoreline Management Act, adopted in 1971. All shorelines are designated urban. The Shoreline Master Plan establishes three management zones adjacent to the Green/Duwamish River: River Zone: This zone includes the first 40 feet from the mean high water mark. Low Impact Zone: This zone includes the second 60 feet from the mean high water mark. High Impact Zone: This zone includes the area from 100 feet to 200 feet from the mean high water mark. n a aa:kYcu ::4..: c: L01 -039 - Shoreline Permit October 8, 2001 Following are the relevant review criteria as contained in the Tukwila Shoreline Regulations (Tukwila Municipal Code, Chapter 18.44) as applied by the City of Tukwila.

CONCLUSION The proposal can be found to not have a probable significant adverse impact on the environment and pursuant to WAC 197 -11 -340, a Determination of Nonsignificance (DNS) is issued for this project This DNS is based on impacts identified within the environmental checklist, attachments, and the above "Final Staff Evaluation for Application No. E01- 015 ", and is supported by plans, policies, and regulations formally adopted by city of Tukwila for the exercise of substantive authority under SEPA to approve, condition, or deny proposed actions. Prepared by: Minnie Dhaliwal Date: September 19, 2001 6 MEMORANDUM To: Steve Lancaster From: Minnie Dhaliwal Date: August 23, 2001 Re: Landscaping for Segale access improvement project - building 734/741 The original proposal included planting trees next to the levy to provide screening and improve N u- the aesthetics of the area since it is in the shoreline vicinity. However the proposed location was 2 not approved by Army Corp of Engineers due to safety concerns and location of monitoring D. D. wells. Staff recommended providing some foundation landscaping to help improve the u_ aesthetics. Applicant has responded that the project meets shoreline regulations without co a providing foundation landscaping and foundation landscaping would not work for them because: t-- i i- 0 • There could be future dock doors in that area. w w • The space is being used for storage (only 734 building). D o • There is an existing berm (levy) that provides screening and the willows that were planted by p N King County will grow soon to further screen the area. w • Truck movement issues. _ U • It is not an access road but parking /loading /storage area and thus does not require foundation u~. 0 landscaping. w z • It is not a new development and no new building is proposed. c) _. Following is a list of provisions in Tukwila Shoreline Master Plan that apply to this access improvement project and suggest the landscaping requirement: A) TMC 18.44.110 General Shoreline regulations: 2. The use does not conflict with the goals and policies of the shoreline master program or the provisions of the Shoreline Act and shoreline regulations. This section in the code implies that the project needs to be consistent with all shoreline master program goals and policies Items # B and C are applicable sections of SMP. B) Shoreline Master Program Chapter 3, defines Low impact zone as a transition area intended to minimize physical and visual impact on the river zone while accommodating shoreline development. The area proposed to be paved is in the low impact environment. The definition of low impact environment implies that any improvements in this zone should minimize the visual impact on the river zone. By providing some foundation landscaping, it will soften the impact of large blank walls. z w CL J U 00 CO 0 - J z C) SMP Chapter 4 Goal and Policies, Shoreline Use Element: Goals: Encourage appropriate development in suitable locations without diminishing the quality of environment along the shorelines of the river. Policies: Aesthetic considerations should be encouraged when contemplating a new development, redevelopment of existing facilities or for general enhancement of shoreline areas. Since the Army Corp of Engineers would not allow any landscaping in the vicinity of the levy because of safety concerns and location of monitoring wells, the only area that is left where some landscaping can be accommodated is next to the building. Foundation landscaping is certainly an aesthetic consideration that should be taken in to account as part of this redevelopment project. D) TMC 18.44.140 Low impact environment regulations: B.2. Access roads shall be located no closer than ten feet to buildings, spur tracks or parking /loading and storage facilities, and the effective setback area shall be suitably landscaped. This shall not prohibit ingress and egress points between an access road and the described facilities. Applicant maintains that the paved area is not an access road, but only a parking /loading and storage area. It appears that it is a combination of an access road (as it provides access to the rear of the building), parking /loading and storage area. B.3. Parking loading and storage facilities shall be appropriately screened from the river with: a. A solid evergreen screen of a minimum six -foot height, or b. Decorative fence six feet high, or c. Large hardy shade or fruit trees at a maximum of 30 feet on center. or d. Earth berms at a minimum of four feet high, suitably planted with live groundcover or natural grass; The existing levy acts an earth berm and thus the project meets code criteria (d).

Box 88028 Tukwila, Washington 98138 Attention: Mark Segale This presents GeoEngineers conclusions regarding bearing capacity of well caps constructed over existing dewatering well casings adjacent to Buildings 734 and 741 at the Segale Business Park. GeoEngineers previously evaluated potential for settlement and embankment stability in regard to proposed fill placement to increase grade behind the subject buildings as described in our May 21, 2001 report. We also developed recommendations for fill placement and compaction. Based on review of well cap "as- built" construction details done by Layton and Sell that you provided, the well caps comprise a circular cap of unreinforced concrete with a diameter of about 5 feet. A 20 -inch diameter steel lid protects 18 -inch diameter corrugated metal pipe (CMP) which extends through the concrete cap to access the dewatering wells. The concrete well cap thickness ranges from about 6 inches at the perimeter to about 2 feet around the collar of the CMP. The dewatering wells comprise 8 -inch diameter schedule 80 polyvinyl chloride pipe located inside the CMP. We understand the well caps will be subjected to H20-44 wheel loads. The structural fill placed to establish subgrade beneath the concrete well caps was compacted and consists of crushed gravel and rock spalls. Based on the Layton and Sell Building 734 and 741 access area drawings dated May 31, 2001, it is our opinion the soil bearing capacity will be adequate to support an H20-44 wheel load with minimal deflection. We estimate the allowable soil bearing capacity is at least 4,000 pounds per square foot. The structural capacity of the concrete well cap may also be evaluated using a subgrade modulus of 300 pounds per cubic inch. GeoEngineers.

King County is signatory to interlocal agreements with the City of Tukwila to provide maintenance and operation of this levee, which provides flood containment for Green River flows affecting the subject properties, together with substantial portions of the Southcenter area in Tukwila. The affected levee segment is part of the larger federally authorized Lower Green River Flood Control Project undertaken by the United States Army Corps of Engineers, under the sponsorship of the City of Tukwila. King County undertakes these responsibilities through its operation of the Green River Flood Control Zone District (GRFCZD). Over the past ten years, substantial investments of public funds have been made in this particular levee location to secure the structural stability and continued function of the Segale Levee. The main purpose of this letter is to emphasize the need for any improvements at this site to be fully consistent with the ongoing presence and operation of the subject levee improvements. These include a series of dewatering wells and an associated pump station. These improvements have been constructed and are operated to provide for adequate levels of stability in otherwise saturated foundation soils supporting the levee structure. The wells penetrate to groundwater depths and are linked to a conveyance manifold draining to a wet well and submerged pumping system, which discharges through the levee prism. The well tubes and associated manifold system have been installed in accordance with design specifications which have not included the types of additional loading now anticipated at this site location. Based on my earlier meeting and discussions with the property owner, I am Steve Lancaster July 16, 2001 Page 2 assuming these uses will include the loading and unloading of tractor trailers similar to those addressed in Section 1.2.5 (C) of the American Association of State Highway and Transportation Officials' (AASHTO's) Standard Specifications, Twelfth Edition. z). w 0:: J 00 • UI J = H N LL w CO = a I- III z � I- w • w O • N O I- w 2 H - . u' ..z w co 0~ Therefore I respectfully request that any approvals for filling and paving of this site uniformly require upgrades of the load- bearing capacity around each of the well caps and the wet well structure, such that bearing capacity will meet or exceed AASHTO HS20 -44 loading requirements. Further, please note that all proposed work potentially affecting the structural configuration or flood containment function of a federally authorized levee will require a formal prior determination by the District Engineer that the subject improvements will not adversely affect the structure or function thereof.

While I have not received the plans yet in the mail, I would like to comment on this proposal to re- grade, fill and pave 1.3 acres near the Green River. The Muckleshoot Tribe traditionally lived along waterways from the Cascade Mountains to areas beyond Lake Washington and Elliot Bay. The Tukwila area is extremely significant, unique, and well documented in its reference to tribal mythologies, prehistoric and historic villages and fishing sites. For decades, archaeological surveys and excavations have identified the Tukwila - Renton area as high potential for archaeological discovery. Due to the location near the Green River, the Cultural Committee will probably request that an archaeological survey before any ground disturbing activities are started. While the region is developed., an unpaved parking lot, such as an overflow area, may be relatively undisturbed. I would like to confirm this with a site visit. As you may be aware, grading can often do irreparable harm to a site. Paving an area is also an impact. Once a site is paved, the information contained in that site is sealed making data recovery impossible. This may be a good solution in order to protect a site permanently. However, the Tribe should be a part of any mitigation to a cultural site of concern to the Tribe. If you decide to request a survey prior to my review of the site plans, I would like to request to review and comment on archaeological report. If you have any questions, please contact me at 360 - 802 -2202, extension 100. ,.�.. ;:1 {xi slt' w':.• ir).+: iiyrs: etti+ 1[ +.t;z7.LTEi6 = _.. ..

The gravel access area is located between the buildings east side and the existing levee. The purpose of the fill is to bring the existing grade level up the finish floor elevation of the existing buildings and to buttress the existing levee. The fill will be placed over an existing gravel surface and the top of the fill will be paved. There are 23 exi.sting__King _County . Department of Natural .. Resources levee well heads in the area _proposed to receive structural fill. The well heads will remain undisturbed and a new 24" diameter manhole cover will be constructed over top of them. The new manhole rim elevations will be about 8- inches above the existing rim elevations. The existing private, access area drainage system will be repaired and upgraded to accommodate the new grades. The drainage system will consist of catch basins, conveyance Layton && Sell, Inc., P.S. 1.0 PROJECT OVERVIEW 321 - 09 Page 1 -1 May 31, 2001 tM x".'ASt3.tw 17 >J . : r'�rt�;57�:'= '^ n.;*,, P5:3't!+,�(;�t?!iN57wx.r; o mmal .rn F.N 1.4 EXISTING CONDITIONS 1.5 DEVELOPED CONDITIONS 1.6 SITE SOILS Layton && Sell, Inc., P.S. 1.0 PROJECT OVERVIEW 321 -09 piping and a coalescing plate oil /water separator. The upgraded drainage system will continue to drain to the existing storm drain system in Andover Park W which drains to the P -17 regional storm water basin. The P -17 basin was constructed as part of the City of Tukwila Andover Industrial Park Comprehensive Drainage Plan. The basin is located just west of the Green River at approximately Minkler Blvd, in the City of Tukwila. Landscape plantings will be placed between the new edge of pavement and the existing top of levee. Refer to the Ken Large Landscape Architect plans for details. The project site area is approximately 5.9 acres and is about 90% impervious and 10% pervious. Of this total, approximately 1.5 acres will be disturbed. The disturbed area consists of approximately 0.3 acres of pavement and 1.2 acres of compacted gravel surface. The site is currently occupied by two commercial buildings (buildings 734 & 741), paved parking and driveway areas, landscaping and the gravel access area on the east side of the buildings. At present, the gravel access area near the building is approximately 3.5 feet below the existing finish floor elevation. Drainage in this area is collected by an existing storm drain system which conveys the drainage to an existing storm drain system in Andover Park W then on to the P -17 regional storm water basin. Developed conditions will replace approximately 0.3 acres of pavement and 1.2 acres of compacted gravel surface with 1.3 acres of pavement and 0.2 acres of gravel surface. Approximately 4,500 cubic yards of fill material will be placed over the existing gravel access area along the buildings east sides. The fill material will bring the existing grade level up to the existing building finish floor elevations and will buttress the existing levee. The existing access area storm drainage system will be repaired and upgraded to accommodate the new grades. The storm drain system's existing discharge to the drainage system in Andover Park W will remain unaltered. Water quality treatment will be provided by a new coalescing plate oil /water separator. The site soils generally consist of dense sand and gravel fill with varying amounts of silt and cobbles overlying native alluvial deposits consisting of silty sand with occasional layers of silt and sandy silt to a depth of about 40 feet. Below this lies fine to medium sand with occasional layers of silty fine sand and sandy silt to a depth of about 75 feet. Refer to appendix A for a geotechnical evaluation by GeoEngineers dated May 21, 2001. 1.7 KING COUNTY CORE AND SPECIAL REQUIREMENT SUMMARY CORE #1. DISCHARGE AT THE NATURAL LOCATION The developed conditions will not alter the sites discharge location. At present, surface runoff from the gravel access area is collected in catch basins and conveyed to the existing storm drainage system in Andover Park W. Under developed conditions, the existing access area Page 1 -2 May 31, 2001 . R?1 *,K,:,.c „ ,;.:. t.^ iM? Aw rt1?,7 i!K•f rasr• storm drain system will be repaired and upgraded and will continue to drain to the storm drain system in Andover Park W. The Andover Park W storm drainage system discharges to the P- 17 regional storm water basin. CORE #2. OFFSITE ANALYSIS CORE #3. FLOW CONTROL 1.0 PROJECT OVERVIEW 321 -09 A downstream analysis of the Andover Park W storm drainage system for the 981 building and site improvements indicate that some portions of the existing Andover Park W storm drain system may become surcharged during a 25 -year event. However, the elevation of the hydraulic grade line was estimated to be several feet below the rims. The downstream analysis modelled the 734/741 site as being 95% impervious surface which assumed that the existing gravel access area was impervious. The results of the downstream analysis indicate that the existing system has adequate capacity to convey and contain the 25 -year design storm event. The existing storm drain system and the street are private. There are no known problems with the existing downstream system. The owner has never observed storm water overflows from any of the rims nor has storm water ever ponded in their streets or parking Tots. Flow control for the site is provided by the P -17 regional storm water basin. The P -17 basin was constructed as part of the City of Tukwila Andover Industrial Park Comprehensive Drainage Plan. The basin is located just west of the Green River at approximately Minkler Blvd, in the City of Tukwila. The only runoff characteristic difference between the existing and developed conditions is that the developed conditions propose to pave over an existing compacted gravel surface. King County's KCRTS model treats compacted gravel surfaces as impervious. Therefore, on the basis of modeling, there will be no change in the runoff volume or peak flow. In practice, we anticipate that any additional runoff volume or peak flow would be insignificant as the result of paving over a compacted gravel surface. CORE #4. CONVEYANCE SYSTEM The existing access area storm water collection /conveyance system will be upgraded to meet the design requirements of a 25 -year design storm event using the rational method. The existing downstream segment to the Andover Park W drainage system will be checked for the 10 -year design storm event using the rational method. The existing Andover Park W drainage system was previously analyzed and was found to have adequate capacity to convey and contain the 25 -year design storm event. CORE #5. EROSION AND SEDIMENT CONTROL Erosion and sediment control will be provided by installing temporary filter media inserts into the catch basins receiving construction site runoff. Site perimeter protection is already provided by the surrounding topography. Construction ingress and egress will occur on private, paved roads. Layton && Sell, Inc., P.S.

WATER QUALITY 1.0 PROJECT OVERVIEW 321 -09 Water quality will be provided by a coalescing plate oil /water separator (CPS). The CPS is designed to treat the 6 -month design storm event. Flows greater than the 6 -month will bypass the CPS and will discharge directly to the existing downstream storm drain system. Larger sediment particles will be captured in catch basin sumps and floating debris will be captured by a tee type structure. SPECIAL REQUIREMENT #1.

Basin 2 will drain to an existing CPS which was previously designed during the building 981 project to accommodate the 734 access area. 2.3.1 WATER QUALITY DESIGN FLOW Per King County, the water quality design flow is defined as 60% of the developed 2 -year peak flow rate, as determined using the KCRTS model with 15- minute time steps calibrated to site conditions. Alternatively, water quality flows may also be estimated using 64% of the 2 -year, 24 -hour precipitation in the SBUH model. The KCRTS method will be used here. Some roof area is included in the water quality basin because it cannot be easily re- routed to bypass the CPS. Where it is reasonable to do so, the roof drainage has been re- routed.

Flows greater than the water quality flow will overflow into a high -flow O bypass riser pipe and will discharge to the existing storm drain system in Andover Park W. z Use Model 612 -SA. 2.4 FLOW CONTROL STRUCTURE 2.4.1 HIGH -FLOW BYPASS FLOW CONTROL STRUCTURE The high -flow bypass structure will be a 12 -inch pipe. The invert is set at elevation 19.81 as determined by the existing storm drain system that it will connect to. The rim of the overflow riser will be set two feet above the invert, so the overflow rim will be at elevation 21.81. Based upon the rational method, the 25 -year peak flow is estimated at 3.49 cfs and the 100 -year peak flow is estimated at 3.77 cfs (see section 2.5 Conveyance Calculations). Determine head over overflow riser rim for the 100 -year event, Q =3.77 cfs: Q = C(L- 0.2H) *H^ /2 where Q = flow (cfs) C = 3.27 + 0.40 H/P (ft) H = hydraulic head above rim of overflow (ft) P = height of overflow rim above invert (2 ft) L = circumference of overflow (3.14 ft) 3.77 = [3.27 + 0.40 H /2] *(3.14 - 0.2H) *HA solving for H = 0.514', say 0.52', thus the 100 -year water surface elevation will be at approximately elevation 22.33 (0.52 + 21.81). Layton && Sell, Inc., P.S. Page 2 -5 May 31, 2001 !um 2.4.2 WATER QUALITY FLOW CONTROL STRUCTURE The water quality flow control structure will be designed as a 6" tee structure with a plate orifice at the bottom and a notch weir at the top. QwQ = 0.39 cfs. QCps = 0.668 cfs. The invert will be set at elevation 20.19. Size Orifice: Q = CA *(2gh) ^0.5 where Q = flow (cfs) C = coefficient of discharge (0.62 for plate orifice) A = area of orifice (sf) h = hydraulic head (ft) g = gravity 32.2 ft/sec Try orifice diameter = 3.5" (0.06681 sf) and head = 1.5' (crest of notch weir, elevation 21.69) Q = 0.62 *0.06681 *(2 *32.2 *1.5) ^0.5 = 0.41 cfs o.k. Check flow to CPS at a 100 -year event with a water surface elevation of 22.33. Qorince = 0.62 *0.066 *(2 *32.2 *(22.33 - 20.19)) ^0.5 = 0.48 cfs Qnotch = C(L- 0.2H) *H ^ 312 where Q = flow (cfs) C = 3.27 + 0.40 H/P (ft) H = hydraulic head above notch rim (0.64 ft) P = height of notch rim above invert (1.5 ft) L = circumference of notch (0.25 ft) Qnotch = [3.27 + 0.40 0.64/1.5] *(0.25 - 0.2 *0.64) *0.64 1 = 0.21 cfs The flow sum of the orifice and the notch is estimated at 0.69 cfs for the 100 -year event. This is approximately equal to the design flow of the CPS, where Qcps = 0.668. o.k. 2.5 CONVEYANCE CALCULATIONS Q = CI Layton && Sell, Inc., P.S. 2.0 DRAINAGE CALCULATIONS 321 -09 This section sizes the conveyance element from CB1 to the existing CB and checks the existing conveyance element from the existing CB to the storm drain system in Andover Park W.

This system is shown on Figure 3.0 Basin Map Downstream Drainage System on page 3 -2. The 734 access area is at the east end of Basin 12 and the 741 access area is at the east end of Basin 13. A downstream analysis of the Andover Park W storm drainage system was previously performed for the 981 building and site improvements (Basins 2 & 11). This analysis indicated that some portions of the Andover Park W storm drain system may become surcharged during a 25 -year event. However, the elevation of the hydraulic grade line was estimated to be several feet below the rims. The downstream analysis modelled Basins 12 & 13 (734/741 site) as being 95% impervious surface which assumed that the existing gravel access area was impervious. The results of the downstream analysis indicate that the existing system has adequate capacity to convey and contain the 25 -year design storm event. The existing storm drain system and the street are private. There are no known problems with the existing downstream system. The owner has never observed storm water overflows from any of the rims nor has storm water ever ponded in their streets or parking lots. The Andover Park W drainage system discharges to the P -17 regional storm water basin. The P -17 basin was constructed as part of the City of Tukwila Andover Industrial Park Comprehensive Drainage Plan. The basin is located just west of the Green River at approximately Minkler Blvd, in the City of Tukwila. 3 -1 May 31, 2001 BASIN 11 AREA= 202,463 SF EX 24' SD °W AS* EX (2 BASIN 2 AREA= 510,845 EX CB • END OF CUL— OE—SAC BASIN 12 AREA =266,407 SF EX SD MI 16 EX SD MI 14 9,910 4,183 SF IN 8 AR 3 —55, EX SD MI 11 BASIN 17 AREA =159,555 SF BUILDING 734/741 PROJECT SITE, SEE FIGURE 1.1 FOR DETAILS GREEN RIVER lil III I {I IIL III III I{{ I�,L 1, {I .I,�I,I {� 111 II III III III III III III ICI 111 11 11 Inch 1 2 I 1 �.... . .. 1 I I.I I I 5I I I I 6 I nG 1 1 WESTCO'IT`� .

Our scope for this study included review of existing geotechnical reports by others, settlement analysis and embattlement stability evaluation based on information derived from our review, and our experience at the Segale Business Park. Specifically, we reviewed a geotechnical report on seepage and stability of the levee by Shannon & Wilson, Inc. dated June 1995, and portions of a geotechnical report for the construction of the business park, performed in about 1972 by Dames & Moore, Inc. Our scope also included developing recommendations for site preparation and earthwork for the proposed improvements. PROJECT UNDERSTANDING Buildings 741 and 734 are located about 50 feet landward from the toe of the existing levee on the left bank of the Green River. We understand finish floor for both buildings at about Elevation 27 feet (King County Aerial Survey Datum). Exterior grade between the buildings and the toe of the levee is at about Elevation 22 feet to provide rail access behind the buildings. The proposed improvements include eliminating the rail access and raising grade by filling between the buildings and the levee to about Elevation 27 feet. The top of the levee is at about Elevation 32.5 feet. The landward slope of the levee is inclined at about 2H: 1V (horizontal:vertical), and the riverward slope of the levee is inclined at about 1.75H:1V. The riverward slope of the levee has a riprap facing with the toe at about Elevation 2 feet. FSecelvea: a /:yI,uu 11 : IDHM; 05/31/2001 10:06 2065751662 Segale Business Park May 21, 2001 pa 2 The Shannon & Wilson report describes site exploration, testing, and analysis for their evaluation of seepage and stability of the levee at the Segale Business Park. Three areas of concern were identified: 1) piping through the levee, 2) failure of the landward slope and toe by high uplift pressures, and 3) failure of the riverward slope of the: levee by toe scour and during rapid drawdown. Shannon & Wilson concluded that the landward slope of the levee was potentially unstable during maximum river flows because of high uplift pressures. They proposed a stabilizing berm at least 5 feet high and placed along the toe; of the landward slope. They recommended a system of relief wells be installed in areas whet installing a stabilization berm was not practical or undesirable because of the existing rail access behind the buildings. Based on review of subsurface conditions disclosed in boring logs prepared by Dames .& Moore, Inc., the native alluvium in the vicinity of Buildings 741 and 734 (Boring B -2) comprises silty sand with occasional layers of silt and sandy silt to a depth of about 40 feet. Below this depth the boring log discloses fine to medium sand with occasional layers of silty fine sand and sandy silt to a depth of about 75 feet. DISCUSSION AND CONCLUSIONS We understand site preparation for the Segale Business Park included a preload surcharge of the building pads before building construction. We further understand that the surcharge fill was placed to about Elevation 32 feet (5 feet above finish floor grade) and extended beyond the building perimeters at full height for a horizontal distance of about 15 feet. On this basis, we conclude that raising grade to Elevation 27 feet between the buildings and the toe of the levee as proposed, should not result in differential settlement of a magnitude that could adversely impact the existing Buildings 741 and 734. It is our further understanding that relief wells were installed along the toe of the levee in this portion of the Business Park as an alternative to placing the stabilization berm. Accordingly, it is our opinion that raising grade as proposed should not adversely :impact levee stability provided the relief wells are protected from damage during construction. • EARTHWORK Site Preparation The earthwork anticipated at the site will consist of stripping and grubbing, excavation and/or recompaction of loose or soft soils, subgrade preparation and ,placement and compaction of structural fill. Prior to grading, the areas to be developed should be stripped of all vegetation and cleared of all surface and subsurface debris. We expect that stripping depths will likely be on the order of 6 to 8 inches. Additional stripping depths will likely be necessary in areas of heavy vegetation. Disturbance to a greater depth should also be expected if earthwork is performed during wet weather.

PAGE 03 We recommend that a member of our staff evaluate the exposed subgrade conditions after removal of vegetation and topsoil. The exposed subgrade can be;evaluated by proofrolling with heavy rubber -tired construction equipment prior to placement of structural fill. During wet weather, it will probably be necessary to evaluate the subgrade by probing with a steel rod rather than proofrolling. Any other soft, loose or otherwise unsuitable areas that are encountered during the subgrade evaluation should be recompacted or overexcavated and replaced with structural fill. Our field representative can assist in determining which will be the most effective method. Wet - Weather Construction Considerations The soil at the site contains a high percentage of fines (soil particles smaller than the No. 200 sieve). The fines cause the soils to be very sensitive to excess • moisture. When the moisture content of these soils is above the optimum percentage, construation traffic will rapidly disturb and soften exposed subgrades. Even when moderately wet, it is very likely that the subgrades will not tolerate repeated passes with construction equipment. Proper compaction of these wet soils is not practical, in our opinion, and they often have to be remaoved from the site and replaced with suitable imported structural fill. Structural Fill Material Structural fill materials should be free of debris, organic contaminants, and rock fragments larger than 6 inches. We recomtend structural fill consist of granular material that is well graded between coarse and fine sizes, and has less than about 10 percent finer than a U.S. No. 200 sieve. Structural Fill Placement All fill placed beneath pavement should be placed as structural fill. Structural fill should be placed in horizontal lifts and uniformly compacted. The appropriate lift thickness will depend on the material and the compaction equipment being used. A loose lift thickness of 8 to 12 inches is typical when using heavy -duty vibratory equipment. All excavations should be wide enough to accommodate the appropriate compaction equipment for the thickness of the fill. The upper 2 feet of structural fill placed below pavement should be compacted to at least 95 percent of the maximum dry density (MDD) determined in accordance with ASTM D -1557 test procedure. pill placed more than 2 feet below the subgrade surface in these areas should be compacted to at least 90 percent of the MDD. Drainage All ground surfaces, pavements, and sidewalks should slope away from the buildings. Surface water runoff should be controlled by a system of curbs, berms, drainage swales, and/or catch basins, and *be discharged into a storm water collection system. Roof drains should be tightlined to discharge into the storm water collection system.

GeoEngineers structures our services to meet the specific needs of our clients. For examile, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfil the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geoteehnical engineering or geologic report is unique, prepared solely for the specific client and projectlsite. No one except the Segale Business Park should rely on this report without first conferring With GeoEngineers. This report should not be applied for any purpose or project except the one originally contemplated. MOST GEOTECHNICAL AND GEOLOGIC FINDINGS AO E PROFESSIONAL OPINIONS Our interpretations of subsurface conditions are based on review of subsurface information developed by others at widely - spaced locations at the site. Site e}cploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data by others an then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. a GEOTECHNICAL ENGINEERING REPORT RECOMMEIkDATIONS ARE NOT FINAL Do not over -rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they werel developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions fevealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation.

A GEOTECHNICAL ENGINEERING OR GEOLOGIC REPORT COULD BE SUBJECT TO MISINTERPRETATION Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre -bid and preconstruction conferences, and by providing construction otservation. CONTRACTORS ARE RESPONSIBLE FOR SITE SAFETY ON THEIR OWN CONSTRUCTION PROJECTS Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to mi.ninzize f isles to on - site personnel and to adjacent properties, READ THESE PROVISIONS CLOSELY Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can cre4te unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngiui ers includes these explanatory "limitations" provisions in our reports to help reduce such • risks. Please confer with GeoEngineers if you are unclear how these `Report Limitations and Guidelines for Use" apply to your project or site.

Structural Fill Placement All fill placed beneath pavement should be placed as structural fill. Structural fill should be placed in horizontal lifts and uniformly compacted. The appropriate lift thickness will depend on the material and the compaction equipment being used. A loose lift thickness of 8 to 12 inches is typical when using heavy -duty vibratory equipment. All excavations should be wide enough to accommodate the appropriate compaction equipment for the thickness of the fill. The upper 2 feet of structural fill placed below pavement should be compacted to at least 95 percent of the maximum dry density (MDD) determined in accordance with ASTM D -1557 test procedure. Fill placed more than 2 feet below the subgrade surface in these areas should be compacted to at least 90 percent of the MDD. Drainage All ground surfaces, pavements, and sidewalks should slope away from the buildings. Surface water runoff should be controlled by a system of curbs, berms, drainage swales, and/or catch basins, and be discharged into a storm water collection system. 1 oof drains should be tightlined to discharge into the storm water collection system.

Geotechnical Engineer . Henderson, P.E. Principal File No. 0291 -019-00 -3130 REPORT LIMITATIONS AND GUIDELINES FOR USE This attachment provides information to help you manage your risks with respect to the use of this report. Z GEOTECHNICAL SERVICES ARE PERFORMED FOR SPECIFIC PURPOSES, w PERSONS AND PROJECTS 2 This report has been prepared for use by the Segale Business Park. GeoEngineers structures c.) p co our services to meet the specific needs of our clients. For example, a geotechnical or geologic w study conducted for a civil engineer or architect may not fulfill the needs of a construction w - 1 contractor or even another civil engineer or architect that are involved in the same project. w 0 Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic 5 report is unique, prepared solely for the specific client and project site. No one except the Segale U Business Park should rely on this report without first conferring with GeoEngineers. This report = should not be applied for any purpose or project except the one originally contemplated. Z 1- O MOST GEOTECHNICAL AND GEOLOGIC FINDINGS ARE PROFESSIONAL w w OPINIONS Our interpretations of subsurface conditions are based on review of subsurface information p N co developed by others at widely- spaced locations at the site. Site exploration identifies subsurface w w w conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data by others and then applied our professional "-- z judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface v U) H = conditions may differ, sometimes significantly, from those indicated in this report. Our report, O 1- conclusions and interpretations should not be construed as a warranty of the subsurface Z conditions. GEOTECHNICAL ENGINEERING REPORT RECOMMENDATIONS ARE NOT FINAL Do not over -rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. 1 Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org G e o E n g i n e e r s ATTACHMENT A A -1 File No. 0291 -019-00 -3130 Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions. A GEOTECHNICAL ENGINEERING OR GEOLOGIC REPORT COULD BE SUBJECT TO MISINTERPRETATION Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre -bid and preconstruction conferences, and by providing construction observation. CONTRACTORS ARE RESPONSIBLE FOR SITE SAFETY ON THEIR OWN CONSTRUCTION PROJECTS Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on -site personnel and to adjacent properties. READ THESE PROVISIONS CLOSELY Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to your project or site.
