Because the requirement for truncated domes was placed on the approved civil plans by the School Districts engineer, the City will require the stamped concrete to be placed at this time However, the

of the puchlists for Yelm High School and Ridgeline Middle School Steve requested a date that the City could reinspect the sites Steve also reminded me that the Temporary Occupancy expires on Oct 31 2007 Groff did have an Electrician on site at YHS today and he indicated that he would be at RMS this afternoon I can only assume that all of the electrical issues have been completed Still remaining are two sewer issues at RMS Please pass this on to the contractors to insure completion not later than Oct 31 2007 Rocky October 25, 2007 From Gary Gonzales of Groff Electric Ray/Mike We are on both sites today replacing disconnects on the Yelm project and punchlist items at Ridgehne It seams that the Cdy of Yelm has decided that they want 3-pole disconnects in lieu if the single pole disconnects that they originally asked for Also someone (not Groff) has drilled out all of the handles of the existing disconnects that were provided Who is the phantom that is tampering with my egwpment~ I am really starting to get tired of all the B S that I have taken from this City and I feel that I have gone the extra mile and expense trying to accommodate them I will talk to Kirk tonight to see where he is regarding their punch list and their dream list (Which changes daily)and will advise you in the morning or maybe late tonight October 25. 2007 Ray Mow of Erickson McGovern PLLC Mike /Gary, Please advise on the status of the City's punchlist for YHS Thank you Raymond Mow AIA Associate Erickson McGovern PLLC RayCa?EricksonMcGovern com October 30, 2007 From Rocky Gary, Steve I was informed today that all punchlist items remaining at YHS, with the exception of the 400 bwlding tank replacement, are complete and ready for inspection Thank You Erling Birkland November 1, 2007 From Rocky Gary The City of Yelm and I reviewed the punchlist at the high school today and found the following Several of the butt splices in the tanks A & B and in the tank behind the auto shop have damage to the insulation It appears as if the crimping tool may have punctured the wnyl insulation In addition, wire nuts are used in the explosion proof ~-box for all wiring The issue of not using a butt splice only pertains to the connection of multiple conductors The two wire connections are required by City Sewer Standards to be connected with a heat shrink butt splice As soon as the damaged butt splices are replaced and the wire nuts for the two wire connections are replaced with butt splices I believe we are complete m regard to the City sewer electrical punchlist November 1.2007 From Steve Harrington Jim Rocky called me first thing this morning I asked him about Ridgeline punchlist He said according to his contractors, the city has come out and did all the inspections and everything is done Rocky was not aware of any such inspections, he was never informed of one I asked Rocky if it would be possible for everyone (City School Dist and Contractors) to come in and sit down at the table to discuss all issues at the schools and get it all out in the open and find out what needs to be completed and get an at tentatroe schedule from everyone when items will be completed Rocky thinks that would be great The following is Rocky s schedule Today Afternoon Mon Morning or Afternoon Tues Afternoon Wed Morrnng tie is on vacation from Wednesday until the 15`" If there is anyway we could make this afternoon work that would probably be best so it will give us time to get issues taken care of before he leaves on vacations Maybe you could talk to Tim this morning when you meet with him then we can schedule something with Rocky, let me know Thanks, November 2, 2007 From Steve Harrington Rocky I only had 2 issues from our dept Sewer still has issues Randy Hatch is going to go out

in correctly, per plans There are 20 parking stalls not put in correctly per plans They are the wrong size I scaled these and compared them to field measurements If you have any further questions I will explain it to you or show you on the plans Thank you The following is taken from the memo I typed and e-mailed to you Ridgelme Middle School Walk Thru November 1, 2007 Grant Nisha and I went out

2005 Page 2 of 4 RE~E~~RD AU6141007 based on the observed soil conditions that ground water may rise to the mid point of the tank, elevation 347 4 The Xerxes program is not capable of determining the groundwater level at which the groundwater would produce a factor of safety of 1 2 It ~s appa~ ent, using the Xerxes criteria, that there is some level between groundwater at the m~dpomt of the tank and groundwater at the top of the tank where the factor of safety would be 1 2 We have more thoroughly analyzed the probable maximum ground water elevation at the STEP tank site and find that the maximum ground water elevation is 347 Please see the attached letter report and attachments by Ed Weltsre of our office We have redesigned the STEP tank location to take advantage of a parking lot island adjacent to the STEP tank location as shown on the approved plans At this revised location the tank would have 0 5 feet greater depth of cover than over the previous location while maintaining the tank inlet invert elevation shown on the approved plans Moreover the cover depth at this revised location would include the additional weight of a concrete walkway over the top of the tank This serves to increase the factor of safety for floatation for the STEP tank With the STEP tank at thrs revised location we have calculated the ground water level at which the tank would have a factor of safety for floatation at 1 2 to 1 Our calculation follows the Xerxes methodology and in fact uses much of the calculated forces directly from the Xerxes calculations Our calculation uses the same unit weights for backfill as the Xerxes calculations Also our calculation uses wet backfill (lighter umt weight) weight where some of the backfill over the top of the tank would be dry (heaver umt weight) We find that the 1 2 to 1 factor of safety for floatation would occur at a ground water level of 351 74, accordrg the calculation as described above This ~s about 4 feet higher than the maximum groundwater level according to our analysis We have heard that rt has been suggested that the Xerxes warranty would be void if the STEP tank is installed without anchorage We queued Xerxes and found out that without anchorage, the Xerxes warranty would be in effect unless the tank floated If the tank floats for whatever reason the Xerxes warranty would not be m effect We find that this ~s m conformance with your letter to us dated December 16 2005 In your letter to us we noted that you state that rt is not feasible to use a piezometer to co- ordinate maintenance of the tank to avoid the high ground water season We are only aware of one maintenance operation that would cause the factor of safety of floatation to be less than 1 2 to one, that would be if the ground water level were ever to reach elevation 351 2 during the high ground water season and the tank were to be pumped empty So long as the ground water level rs below 351 7 that tank could be pumped empty at any time and the factor of safety for floatation would be greater than 1 2 to I One might try to pump the tank empty for one of several reasons RECEIVED AUG 14 2001 Calculate Ground Water Elevation Required to Produce 1 2 to 1 Factor of Safety for Floatation at the 50,000 STEP tank at Ridgehne Junior High School Since the Xerxes program is not able to calculate the ground water level at which the factor of safety falls to 1 2 to 1, a calculation needs to be made to estimate the level This calculation should be conservative, that it to say it should error of the side of showing a lower groundwater level than on showing a higher level fora 1 2 factor of safety To improve the factor of safety, the calculation accounts for locating the tank under an island m the parking lotto increase the cover over the top of the tank by 0 5 feet to a total cover of 4 2 feet The 4 2 feet of cover includes a 4 inch thick concrete slab over the tank Xerxes noted that their method of calculating the factor of safety for tank floatation is based on the method outlined m the Petroleum Equipment Institute Recommended Practice 100 (PEI/RP 100) This calculation is made m accordance with the recommended practice fisted m PEI/RP 100 and uses the unit weights fisted m the Xerxes calculations and uses the backfill surface area same area above the tank as does the Xerxes calculation The calculation shows that the 1 2 factor of safety for floatation would at a ground water level below the top of the tank Thus some amount of the backfill below the top of the tank would be dry To help keep the calculation conservative, the unit weight of the backfill below the top of the tank is taken as though the backfill ~s wet Thrs calculation uses the Xerxes Dipstick Calibration Chart for this tank to calculate the tank displacement volume at the 1 2 factor of safety ground water level A correction factor is used with the Dipstick Chart volumes to make the displaced volume of the tank meet or exceed the value fisted m the Xerxes floatation calculations The calculation shows that the 1 2 factor of safety would occur at a groundwater elevation of 351 71 feet Step One Determine the werght of the backfill above the tank Use the weight of 408,624 12 lb from the Xerxes calculation for groundwater level at the top of the tank with 3 7 feet of backfill See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/16/05 alculate the weight of the 4" concrete slab over the top of the tank Per erxes the allowable size of the slab is 70 08 feet by 14 feet Use 150 lb/ft3 (per Xerxes) to calculate the weight of the slab `~~,1 70 08' x 14' x 4"/12" per foot x 150 lb/ft3 = 49,0561b --'7 See Xerxes calculation sheet for "Non-Anchored Water at Tank __~~,,ff Top" dated

consisted maznly of alder, which is a decrduous tree that drops tts leaves each Fall The leaves would add to the fine sods, nutrients and abundant water to produce a pond bottom biomat that would seriously reduce infiltration rates This condition may also have been influenced by localized groundwater mounding beneath the pond due to the concentration of runoff m the pond As such, the GEODATA groundwater hazazd mapping for this pond azea also reflects poor pond performance due to poor maintenance and localized mounding during an extremely wet period Hence, the actual local maximum shallow groundwater level is most likely somewhere between elevations 345 ft and 348 ft Retunung to the staimng observed m the excavation (elevation 347 4 ft), tt is probable that the maxunum excursion was about 347 ft, groen that capillary rise m the soil would result in a slight elevation of upwazd wetting front and stain mazks in the soil Recently measured water levels m the athletic field azea west of the school shows present water levels to be about 346 5 ft Grven that there is most likely some rise m the phreatic surface from the athletic field are to the STEP Tank azea, a present level of 347 to 347 5 ft would be a reasonable assumption Finally, measurements were attempted m the Hawks Landing Pond ~mmedrately to the north of the STEP Tank azea This pond has remained dry through this period and the pond bottom is 348 4 ft Based on the foregoing, it is cleaz that the shallow groundwater level m the STEP Tank azea ~s presently below 348 4 ft and is most likely about 347 ft This present conditions ~s occumng during a record rainfall period as noted above CONCLUSIONS Based on the foregoing, rt rs concluded that the approxunated maximum shallow groundwater level of record m the vicimty of the protect srte ~s about 347 ft and is most likely occurring reoccumng at the present time Should you have any further questions or requrre cianfication, kindly contact me at (360)352-9456 Yours

RF~E~~ea AU6~ 41007 based on the observed soil condmons that ground water may rise to the mid point of the tank elevation 347 4 The Xerxes program is not capable of determining the groundwater level at which the groundwater would produce a factor of safety of 1 2 It is apparent, using the Xerxes criteria, that there is some level between groundwater at the midpoint of the tank and groundwater at the top of the tank where the factor of safety would be 1 2 We have more thoroughly analyzed the probable maxunum ground water elevation at the STEP tank site and find that the maximum ground water elevation is 347 Please see the attached letter report and attachments by Ed Wiltsie of our office We have redesigned the STEP tank location to take advantage of a parking lot island adjacent to the STEP tank location as shown on the approved plans At this revised location the tank would have 0 ~ feet greater depth of cover than over the previous location while maintaining the tank inlet invert elevation shown on the approved plans Moreover the cover depth at this revised location would include the additional weight of a concrete walkway over the top of the tank This serves to increase the factor of safety for floatation for the STEP tank With the STEP tank at this revised location we have calculated the ground water level at which the tank would have a factor of safety for floatation at 1 2 to 1 Our calculation follows the Xerxes methodology and m fact uses much of the calculated forces directly from the Xerxes calculations Our calculation uses the same unit weights for backfill as the Xerxes calculations Also our calculation uses wet backfill (lighter unit weight) weight where some of the backfill over the top of the tank would be dry (heavier unit weight) We find that the 1 2 to 1 factor of safety for floatation would occur at a ground water level of 351 74, according the calculation as described above This is about 4 feet higher than the maximum groundwater level according to our analysis We have heard that rt has been suggested that the Xerxes warranty would be word rf the STEP tank is installed without anchorage We queried Xerxes and found out that without anchorage, the Xerxes warranty would be m effect unless the tank floated If the tank floats for whatever reason, the Xerxes warranty would not be m effect We find that this is m conformance wrih your letter to us dated December 16, 2005 In your letter to us we noted that you state that rt is not feasible to use a piezometer to co- ordinate maintenance of the tank to avord the hrgh ground water season W e are only aware of one maintenance operation that would cause the factor of safety of floatation to be less than 1 2 to one, that would be if the ground water level were ever to reach elevation 351 2 during the high ground water season and the tank were to be pumped empty So long as the ground water level is below 351 7 that tank could be pumped empty at any time and the factor of safety for floatation would be greater than 1 2 to 1 One might try to pump the tank empty for one of several reasons RECEIVED Calculate Ground Water Elevation Required to Produce l~~rt'o114Factor of Safety for Floatation at the 50,000 STEP tank at Ridgehne Junior High School Since the Xerxes program is not able to calculate the ground water level at which the factor of safety falls to 1 2 to 1, a calculation needs to be made to estimate the level This calculation should be conservative, that rt to say rt should error of the side of showing a lower groundwater level than on showing a higher level fora 1 2 factor of safety To improve the factor of safety, the calculation accounts for locating the tank under an island m the parking lot to increase the cover over the top of the tank by 0 5 feet to a total cover of 4 2 feet The 4 2 feet of cover includes a 4 inch thick concrete slab over the tank Xerxes noted that their method of calculating the factor of safety for tank floatation is based on the method outlined m the Petroleum Equipment Institute Recommended Practice 100 (PEI/RP 100) This calculation is made m accordance with the recommended practice fisted m PEURP 100 and uses the unit weights fisted m the Xerxes calculations and uses the backfill surface area same area above the tank as does the Xerxes calculation The calculation shows that the 1 2 factor of safety for floatation would at a ground water level below the top of the tank Thus some amount of the backfill below the top of the tank would be dry To help keep the calculation conservative, the unit weight of the backfill below the top of the tank ~s taken as though the backfill is wet This calculation uses the Xerxes Dipstick Cahbrat~on Chart for this tank to calculate the tank drsplacement volume at the 1 2 factor of safety ground water level A correction factor is used with the Dipstick Chart volumes to make the displaced volume of the tank meet or exceed the value listed m the Xerxes floatation calculations The calculation shows that the 1 2 factor of safety would occur at a groundwater elevation of 351 71 feet Step One Determine the weight of the backfill above the tank Use the weight of 408,624 12 lb from the Xerxes calculation for groundwater level at the top of the tank with 3 7 feet of backfill See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/16/05 Calculate the weight of the 4" concrete slab over the top of the tank Per Xerxes the allowable size of the slab is 70 08 feet by 14 feet Use 150 lb/ft3 (per Xerxes) to calculate the weight of the slab 70 08' x 14' x 4"/12" per foot x 1501b/ft; = 49,056 lb See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/22/05 Calculate the weight of the 2" of backfill under the concrete slab Use 100 lb /ft3 (per Xerxes) for dry backfill 70 08' x 14' x 2"/12" per foot x 1001b/ft3 = 16,352 lb Add the weight of the 50,000 gallon tank = 18,300 Ib Sheet 1 of 2 woa dloasaluax mmm;e

the mid point of the tank, elevation 347 4 The Xerxes program is not capable of determining the groundwater level at which the groundwater would produce a factor of safety of 1 2 It is apparent, using the Xerxes criteria, that there is some level between groundwater at the midpoint of the tank and groundwater at the top of the tank where the factor of safety would be 1 2 We have more thoroughly analyzed the probable maximum ground water elevation at the STEP tank site and find that the maximum ground water elevation is 347 Please see the attached letter report and attachments by Ed Wiltsie of our office We have redesigned the STEP tank location to take advantage of a parking lot island adJacent to the STEP tank location as shown on the approved plans At this revised location the tank would have 0 5 feet greater depth of cover than over the previous location while maintaining the tank inlet invert elevation shown on the approved plans Moreover the cover depth at this revised location would include the additional weight of a concrete walkway over the top of the tank This serves to increase the factor of safety for floatation for the STEP tank With the STEP tank at this revised location we have calculated the ground water level at which the tank wou]d have a factor of safety for floatation at 1 2 to 1 Our calculation follows the Xerxes methodology and in fact uses much of the calculated forces directly from the Xerxes calculations Our calculation uses the same unit weights for backfill as the Xerxes calculations Also our calculation uses wet backfill (fighter unit weight) weight where some of the backfill over the top of the tank would be dry (heavier unit weight) We find that the 1 2 to 1 factor of safety for floatation would occur at a ground water level of 351 74, according the calculation as described above This is about 4 feet higher than the maximum groundwater level according to our analysis We have heard that it has been suggested that the Xerxes warranty would be void if the STEP tank is installed vnthout anchorage W e queued Xerxes and found out that without anchorage, the Xerxes warranty would be m effect unless the tank floated If the tank floats for whatever reason, the Xerxes warranty would not be m effect We find that this is m conformance with your letter to us dated December 16, 2005 In your letter to us we noted that you state that it is not feasible to use a piezometer to co- ordinate maintenance of the tank to avoid the high ground water season We are only aware of one maintenance operation that would cause the factor of safety of floatation to be less than 1 2 to one, that would be if the ground water level were ever to reach elevation 351 2 during the high ground water season and the tank were to be pumped empty So long as the ground water level is below 351 7 that tank could be pumped empty at any time and the factor of safety for floatation would be greater than 1 2 to 1 One might try to pump the tank empty for one of several reasons RECEIVE AU614 ?007 Calculate Ground Water Elevation Required to Produce 1 2 to 1 Factor of Safety for Floatation at the 50,000 STEP tank at Ridgehne Junior Hrgh School Since the Xerxes program rs not able to calculate the ground water level at which the factor of safety falls to 1 2 to 1, a calculation needs to be made to estimate the level This calculation should be conservative, that rt to say rt should error of the side of showing a lower groundwater level than on showing a higher level fora 1 2 factor of safety To improve the factor of safety, the calculation accounts for locating the tank under an island m the parking lot to increase the cover over the top of the tank by 0 5 feet to a total cover of 4 2 feet The 4 2 feet of cover includes a 4 inch thick concrete slab over the tank Xerxes noted that their method of calculating the factor of safety for tank floatation is based on the method outlined m the Petroleum Equipment Institute Recommended Practice 100 (PEI/RP 100) This calculation is made m accordance with the recommended practice fisted m PEI/RP 100 and uses the unit weights listed m the Xerxes calculations and uses the backfill surface area same area above the tank as does the Xerxes calculation The calculation shows that the 1 2 factor of safety for floatation would at a ground water level below the top of the tank Thus some amount of the backfill below the top of the tank would be dry To help keep the calculation conservative, the unit weight of the backfill below the top of the tank ~s taken as though the backfill is wet This calculation uses the Xerxes Dipstick Calibration Chart for this tank to calculate the tank displacement volume at the 1 2 factor of safety ground water level A correction factor is used with the Dtpstcck Chart volumes to make the displaced volume of the tank meet or exceed the value fisted m the Xerxes floatation calculations The calculation shows that the 1 2 factor of safety would occur at a groundwater elevation of 351 71 feet Step One Determine the weight of the backfill above the tank Use the weight of 408,624 12 lb from the Xerxes calculation for groundwater level at the top of the tank with 3 7 feet of backfill See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/16/05 Calculate the weight of the 4" concrete slab over the top of the tank Per Xerxes the allowable size of the slab is 70 08 feet by 14 feet Use 150 Ib/ft3 (per Xerxes) to calculate the weight of the slab 70 08' x 14' x 4"/12" per foot x I SO lb/ft3 = 49,056 lb See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/22/05 Calculate the weight of the 2" of backfill under the concrete slab Use 100 lb /ft3 (per Xerxes) for dry backfill 70 08' x

prevent the growth of woody vegetation on the pond bottom or side slopes Based on visual observations the growth m the pond consisted mainly of alder, which ~s a deciduous tree that drops its leaves each Fall The leaves would add to the fine soils, nutrients and abundant water to produce a pond bottom biomat that would seriously reduce infiltration rates Tlns condrt~on may also have been influenced by localized groundwater mounding beneath the pond due to the concentration of runoff m the pond As such, the GEODATA groundwater hazard mapping for this pond area also reflects poor pond performance due to poor maintenance and localized mounding during an extremely wet period Hence, the actual local maxrmum shallow groundwater level is most likely somewhere between elevations 345 ft and 348 ft Returning to the staining observed m the excavation (elevation 347 4 ft), it is probable that the maximum excurswn was about 347 ft, given that capillary rise m the soil would result m a slight elevation of upward wetting front and stain marks m the soil Recently measured water levels m the athletic field area west of the school shows present water levels to be about 346 5 ft Given that there is most lilcely some rise m the phreatic surface from the athletic field are to the STEP Tank azea, a present level of 347 to 347 5 ft would be a reasonable assumption Finally, measurements were attempted m the Hawks Landing Pond inuned~ately to the north of the STEP Tank area This pond has remained dry through this period and the pond bottom ~s 348 4 ft Based on the foregoing, rt is clear that the shallow groundwater level m the STEP Tank area is presently below 348 4 ft and is most likely about 347 ft This present conditions is occumng during a record raznfall period as noted above CONCLUSIONS Based on the foregoing, ~t is concluded that the approximated maximum shallow groundwater level of record m the v~cimty of the project site is about 347 ft and is most likely occurring reoccurring at the present time Should you have any further questions or require clanfication, kindly contact me at (360)352-9456 Yours very truly, J W MORRISSETTE & ASSOCIATES INC P S

the observed sod conditions that ground water may rise to the mid point of the tank, elevation 347 4 The Xerxes program is not capable of determinuig the groundwater level at which the groundwater would produce a factor of safety of 1 2 It is apparent, using the Xerxes criteria, that there is some level between groundwater at the midpoint of the tank and groundwater at the top of the tank where the factor of safety would be 1 2 We have more thoroughly analyzed the probable maximum ground water elevation at the STEP tank site and find that the maximum ground water elevation rs 347 Please see the attached letter report and attachments by Ed Wrltsie of our office We have redesigned the STEP tank location to take advantage of a parking lot island adjacent to the STEP tank location as shown on the approved plans At this revised location the tank would have 0 5 feet greater depth of cover than over the previous location while maintaining the tank inlet invert elevation shown on the approved plans Moreover the cover depth at this revised location would include the additional weight of a concrete walkway over the top of the tank This serves to increase the factor of safety for floatation for the STEP tank With the STEP tank at this revised location we have calculated the ground water level at which the tank would have a factor of safety for floatatron at 1 2 to 1 Our calculation follows the Xerxes methodology and m fact uses much of the calculated forces directly from the Xerxes calculations Our calculation uses the same umt weights for backfill as the Xerxes calculations Also our calculation uses wet backfill (lighter unit weight) weight where some of the backfill over the top of the tank would be dry (heavier umt werght) We find that the 1 2 to 1 factor of safety for floatation would occur at a ground water level of 351 74, according the calculation as described above This is about 4 feet higher than the maximum groundwater level according to our analysis We have heard that it has been suggested that the Xerxes warranty would be void if the STEP tank is installed without anchorage We queried Xerxes and found out that without anchorage, the Xerxes warranty would be m effect unless the tank floated If the tank floats for whatever reason, the Xerxes warranty would not be m effect We find that this is m conformance with your letter to us dated December 16, 2005 In your letter to us we noted that you state that it is not feasible to use a piezometer to co- ordinate maintenance of the tank to avoid the high ground water season We are only aware of one maintenance operation that would cause the factor of safety of floatation to be less than 1 2 to one, that would be rf the ground water level were ever to reach elevatron 351 2 during the high ground water season and the tank were to be pumped empty So long as the ground water level is below 351 7 that tank could be pumped empty at any time and the factor of safety for floatation would be greater than 1 2 to 1 One might try to pump the tank empty for one of several reasons RECEIVED AUG 1 4 2~si Calculate Ground Water Elevatron Reqiured to Produce 1 2 to 1 Factor of Safety for Floatation at the 50,000 STEP tank at Ridgehne Junior Htgh School Since the Xerxes program is not able to calculate the ground water level at which the factor of safety falls to 1 2 to 1, a calculation needs to be made to estimate the level This calculation should be conservative, that rt to say rt should error of the side of showing a lower groundwater level than on showing a higher level fora 1 2 factor of safety To improve the factor of safety, the calculation accounts for locating the tank under an island m the parking lot to increase the cover over the top of the tank by 0 5 feet to a total cover of 4 2 feet The 4 2 feet of cover includes a 4 inch flock concrete slab over the tank Xerxes noted That then method of caicutating the factor of safety for tank floatation is based on the method outlined m the Petroleum Egmpment Institute Recommended Practice 100 (PEI/RP 100) This calculation is made m accordance with the recommended practice fisted m PEURP100 and uses the unit wetghts listed m the Xerxes calculations and uses the backfill surface area same area above the tank as does the Xerxes calculation The calculation shows that the 1 2 factor of safety for floatation would at a ground water level below the top of the tank Thus some amount of the backfill below the top of the tank would be dry To help keep the calculation conservative, the unit weight of the backfill below the top of the tank is taken as though the backfill is wet This calculation uses the Xerxes Dipstick Calibration Chart for tins tank to calculate the tank displacement volume at the 1 2 factor of safety ground water level A correction factor is used with the Dipstick Chart volumes to make the displaced volume of the tank meet or exceed the value listed in the Xerxes floatation calculations The calculation shows that the 1 2 factor of safety would occur at a groundwater elevation of 351 71 feet Step One Determine the weight of the backfill above the tank Use the weight of 408,624 12 Ib from the Xerxes calculation for groundwater level at the top of the tank with 3 7 feet of backfill See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/16/05 Calculate the weight of the 4" concrete slab over the top of the tank Per Xerxes the allowable size of the slab is 70 08 feat by 14 feet Use 150 lb/ft3 (per Xerxes) to calculate the weight of the slab 70 08' x 14' x 4"/12" per foot x 1501b/ft3 = 49,0561b See Xerxes calculation sheet for "Non-Anchored Water at Tank Top" dated 12/22/05 Calculate the weight of the 2" of backfill under the concrete

Based on visual observations the growth m the pond consisted mainly of alder, which ~s a deciduous tree that drops its leaves each Fall The leaves would add to the fine soils, nutrients and abundant water to produce a pond bottom bromat that would seriously reduce urfiltratron rates This condrtion may also have been influenced by localized groundwater mounding beneath the pond due to the concentration of runoff m the pond As such, the GEODATA groundwater hazazd mapping for thrs pond azea also reflects poor pond performance due to poor maintenance and localized mounding during an extremely wet period Hence, the actual local maxunum shallow groundwater level rs most likely somewhere between elevations 345 ft and 348 ft Retunung to the staining observed in the excavation (elevation 347 4 ft), it is probable that the maximum excursron was about 347 ft, given that capillary rise m the soil would result m a slight elevatron of upward wetting front and stain mazks m the soil Recently measured water levels m the athletic field azea west of the school shows present water levels to be about 346 5 ft Given that there is most likely some rise m the phreahc surface from the athletic field are to the STEP Tank area, a present level of 347 to 347 5 ft would be a reasonable assumption Finally, measurements were attempted m the Hawks Landing Pond munedrately to the north of the STEP Tank area This pond has remained dry through this period and the pond bottom ~s 348 4 ft Based on the foregoing, it ~s clear that the shallow groundwater level m the STEP Tank azea is presently below 348 4 ft and is most likely about 347 ft This present conditions is occumng during a record rainfall period as noted above CONCLUSIONS Based on the foregoing, it is concluded that the approximated maxrmum shallow groundwater level of record m the vicinity of the project site is about 347 ft and is most likely occurnng reoccumng at the present tune Should you have any further

Htgh School August 11, 2006/Sumary of Results Dear Mr Btrkland This fire flow test was conducted to evaluate the fire flow capacity of the system with a higher degree of certainty than is possible with the earlier fire flow tests conducted May 31, 2006 The fire flow tests conducted May 31, 2006 and the fire flow projection calculations indicated that the system could provide 1,426 gpm at 20 psi residual pressure at one fire hydrant and could provide 1,279 gpm at another fire hydrant at 20 psi residual pressure Subsequent to conducting the fire flow tests, it was discovered that one of the City's reservoirs was out of service Since the required fire flow is 1,438 gpm with a minimum pressure of 20 psi, the fire flow test and pro~ecUOn calculations indicated that the system could not provide the required minimum fire flow Additionally, the fire flow calculation for the earlier fire flow tests required projections of the fire flow capability of the system since the actual flow from the hydrants during the tests was less than 1,438 gpm Projecting fire flow capacity introduces some uncertainty into the fire flow calculation Moreover, a reduced pressure backflow assembly (RPBA) was installed on the 8 inch city line that serves the entire school site, including the city owned fire loop and city owned fire hydrants As far as fire flow is concerned the RPBA effectively reduces the available water pressure Thus the installation of the RPBA introduces more uncertainty into trying to project the fire flow capacity of the system These current fire flow tests were conducted with the RPBA installed and operational and were conducted using a discharge somewhat higher than the required minimum fire flow and were conducted with all of the City's reservoirs in service Thus the certainty of the results for this fire flow test is considerably higher than using the results of the earlier fire flow test While discharging more than 1,438 gpm from the fire hydrants, the residual pressure exceeded the minimum required 20 psi For the conditions that existed during this fire flow test, in particular water levels in the Public Works Tank at 138 93 fr in the Downtown Tank at 110 76 fr and in the Baker Hill Tank at 56 85 fr ,the system is capable of exceeding the 1,438 gpm minimum required flow while maintaining residual pressure exceeding the 20 psi minimum required residual pressure Mr Erhng Kirkland, Director of Fac~lrties August 15, 2006 Page 2 of 2 A reduction m reservoir levels would reduce the fire flow capacity of the system According to our understanding of the Fire Marshal's requirements for a new building, the water system serving the fire system should be able maintain fire flow capacity above the minimum required when the reservoirs are drawn down to the bottom of the allotted fire flow storage Since the RPBA reduces the pressure m the fire loop, the RPBA makes the fire loop act as though the reservoirs are drawn down approximately 16 feet lower than the actual reservoir levels In the immediate future a significant pomon of the 8" fire loop will be replaced with 10 inch ]me This will have the effect of increasing the fire flow capacity of the loop, but will not change the pressure drop that occurs across the RPBA Very truly yours Jerome W Mornssette & Associates Inc , P S Doug Eklund, P E Senior Protect Engineer Attachments CC Mr Jim

Ftre Flow Results Report August 14 2006 By Scott G Severs Condrtrons Our office conducted two fire flow tests for the Yelm School District at the Yelm High School on August 11, 2006 between the hours of 10 00 am and 10 30 am in cooperation with the City of Yelm Personnel conducting the flow testing were Scott Severs Sr Engineering Technician(JWMBA), Doug Eklund Sr Pro)ect Engineer (JWM&A) and Edward Smith Yelm Water Dept (City of Yelm) The equipment utilized for the flow testing were two Pollard hydrant diffusers equipped with pilot and pressure gages Three pressure recorders (Dickson PR 300 electronic recording devices) and one 0-200 psi (Dwyer digital pressure gage) were used to record static and residual pressures before, during and after fire flow testing See attached map for gage locations The well pumps were off and all three City reservoirs were on line The reservoir levels were recorded prior to each flow test (See Exhibits 2 and 3) Static pressures were recorded prior to each flow test and residual pressures were recorded during each flow test (See Exhibits 2 and 3) There is an 8" reduced pressure backflow assembly installed at the Southeast corner of the school site and all flow into the site flows through the RPBA, to include the City owned Fire Loop and Hydrants The static pressure drop across the RPBA is 7 to 8 psi (See Exhibit 4 pressure recorder results graph "Downloaded Data") Flows were recorded at two hydrants while flowing through two ports simultaneously at the flow locations (See attached map) The first flow test had both pilot gages attached to a single hydrant The second flow test had the pilot gages attached to separate hydrants (See attached map) One of the pressure recorders was deployed upstream of the RPBA and the other two with the digital pressure gage were deployed downstream of the RPBA (See attached map for locations) The first flow test was conducted at 10 04 am (See Exhibit 2) and the second flow test was conducted at 10 18 am (See Exhibit 3) Flow Results The first fire flow test was conducted with both pilot gages attached to a single hydrant located at the North end of the school sites situated between the Gymnasium and the newly constructed High School Building The calculated combined flow at 20 psi residual for this flow test is 1782 gpm (See Exhibit No 1) Civil / Municipal / Geotechnical Engmeenng and Planning The second flow test was conducted with the pitot gages attached to separate hydrants One was attached to the same hydrant as the lust test and the other was attached to a hydrant located near the southerly end of the school site adjacent to the Shop Bwlding The calculated combined flow at 20 psi residual for this test was 1688 gpm (See Exhibit No 1) The requued flow for the High School is 1438 gpm or better Summary Exhibit No 1 summarizes the flow test results and the flows protected out to 20 psi residual pressure Exhibit No 2 shows recorded data from the first flow test Exhibit No 3 shows recorded data from the second flow test Exhibit No 4 is a graph that shows the recorded pressures before, during and after the testing both upstream of the RPBA and downstream of the RPBA Exhibit No 5 is a copy of the Pollard Flow Test Chart Calculator and Hydrant inlet coeffiaents Exhibit No 6 is a copy of the speafication sheet for the installed RPBA with head loss charts The pressure drop across the RPBA increased to approximately 14 psi during flow conditions This is a considerable pressure drop and is cause for some concern with the overall diminished capacity that existed within the system pnor to the installation of this device The head loss for this device at the flows recorded should be near 10 psi (See Exhibit 6) The fire flow testing results demonstrate that the looped portion of the system under these conditions will meet the minimum fire flow regwrement of 1438 gpm The final calculated flow results for the two flow tests under these conditions, protected out to 20 psi residual pressure are 1782 gpm and 1688 gpm Flow Test August 2006 Exhibit No 1 Hydrant Flre Flow Tests at the Yelm Hlgh School August 11, 2006 Flow Test No 1 August [1 20061004 am Reservoir Pumps

developed for installation of the tank and the plan, detatl, and calculations were submitted to you for review and obtained Ctty of Yelm approval The plan, detatl, and calculations addressed flotation and conformance the tank manufacturer's mstallatton requirements The plan and detatl called for tank installation m a parking lot island with a 4 Inch thick concrete slab above the tank The tnstallatton in the parking lot tsland was rntended to increase the total depth of cover over the tank and the 4 inch thick concrete slab was rntended to add weight to the tank cover materials The design of the 4 inch concrete slab and the parking lot tsland provided for extending the slab at least 1 foot beyond the overall length and overall width of the tank m accord with the manufacturer's recommendations A copy of this Ctty of Yelm approved plan and detail were provided to the Contractor Although the Contractor managed to install the tank in accord with the manufacturer's recommendations for excavation, dewatenng, and materials, the installed location did not conform to the plans and details This problem became apparent when the Contractor attempted construct formwork for the tsland and discovered that one of the pump risers would have been located m a curb ramp m the tsland At this point the Contractor shifted the island curb northerly and shifted a curb tine opposite the tsland northerly to obtain adequate tank cover while maintaining pavement width The concrete curbs were constructed in these locations and the area around the tsland was paved We mvesrigated the situation and found the installation would have had two problems First, the relocated curb would not have allowed construction of the concrete slab to extend 1 foot beyond the overall length and width of the tank Second, the concrete curb was constructed low so that the tank would have several inches less cover than the plan and detail called for Without correction, the tank flotation calculations would be mvahd Mr Jim Gibson, PE August 23, 2006 Page 3 of 3 surface of the portion outside the curb must meet the finished surface of the pavement The as-built location of the STEP line END OF LINE CLEANOUT it too close to the end of the monolithic slab and will result m asphalt pavement farlure unless the cleanout is relocated Further, with the as-built location of the cleanout the monohth~c slab is at nsk should maintenance of the cleanout valve or other cleanout maintenance be requued We recommend that the pipe launch port and valve be moved as shown on the plans and details Given the short timeline to accomplish this work and the adverse impact to the School D~stnct if the construction does not comply with our revised detarls, we recommend that a Jerome W

was not installed as designed A revision must be submitted to the City Engineer for approval and installed pursuant to the revised approval / The temporary Certificate of Occupancy may be issued even if the commons area and kitchen within the 300 wing are not complete, provided that access to this area is controlled and an access control plan is submitted to the Building Official, that a modified exiting plan is submitted to the Building Official, and the fire suppression and alarm system covers 100% of the building The following items are required before issuance of final certificate of occupancy for the any building at the School site / All conditions of the land use approval and Mitigated DNS must have been met / The off-site transportation system improvements required by the Mitigated DNS on SR 507 must be installed and approved no later than July 31, 2007 / It appears that the parking lot was not striped pursuant to the approved plans and contains more compact spaces than allowed / Landscaping must be installed pursuant to the approved landscaping plans Otherlssues You requested that the District be allowed to connect the irrigation system at Ridgeline to a fire hydrant to irrigate two fields and landscaping until the site is connected to Reclaimed Water This request is approved subtect to the following conditions / All potable water is metered and paid for by the District at potable water rates / An approved backflow prevention device with up to date certification be installed and maintained between the hydrant and the connection to the irrggation system at all times / The area surrounding the temporary hydrant connection be secured in a manner approved, in writing, by the Public Works Department August 23 2006 Page 2 of 3 / The connection is not authorized after September 26, 2006, unless extended, in writing, by the Community Development Department As soon the reclaimed water system is charged at the Htgh School, you may schedule the dye test through Kevin Ray at the Public Works Department Upon successful completion of the dye test and certification of the cross connection control program on the site, but before beneficial use of reclaimed water on the property, Stephanie Ray will provide a reclatmed water users agreement for the Districts execution I spoke with Kevin Ray after our meeting this morning and he stands ready to conduct the dye tests upon your request The City is holding proceeds from an assigned savings from Hawks Landing for use by the District in construction of improvements on SR 507 At the point that construction plans are approved by the Washington State Department of Transportation and a contract for the construction has been executed by the District, the Ctty will release the funds to the Distract A letter requesting release of funds to the Community Development Department at the time the contract is executed will serve as a the mechanism for the City to process a warrant During the meeting you indicated that buses would be entering Rtdgeline from 107"' Street, using Mill Road and the intersection of Mdl Road and SR 507 After the meeting, you telephoned to let me know that you had followed on this issue with the Districts Transportation Office and that no buses would be making a left hand turn from SR 507 onto Mill Road As you know, the reason that the Mitigated DNS did not require any improvements to Mdl Road was because the District had indicated that no buses would be using this intersection This was noted in both the MDNS and the land use approval issued for Rtdgeline Junior High Thank you for quickly addressing this concern If you have any questions regarding the above information, please don't hesitate to contact me at the Community Development

2/23/06 I asked if he got a timeline from you of when we could expect information back from you so we can make necessary ad/ustments to our irrigation design In time to get it priced, approved, ordered and installed prior to school starting in another 6 months Can we get a timeline on when we can have a decision on the irrigation system Also, please give us a status of the City's irrigation design for bringing the reclaimed water up MIII Road to the NE corner of MIII Pond sites This could also prove to be a critical path item if it is not on schedule to be installed by April 3/10/2006

70 psi range at 62 gpm, the flow you Indicated for the school We have analyzed the revised flow demands you have requested and have verified the pressures you can anticipate at Rldgellne to still be In the 67 - 70 psi range You should anticipate a range of 80 - 85 psI at the high school at 160 gpm 3/10/2006 Page 2 of 3 ~~ As Indicated at the meeting, the more significant Issue is the duration of your watering cycle In order to manage the total volume of water produced during the peak month, the City will have to regulate the total watering cycle of each of Its users Therefore, some of the schools anticipated 13-hour watering days will have to be restricted to perhaps 10 hours per day at 160 gpm This will become less of an Issue as time goes by because more reclaimed water will be produced as the system expands The reclaimed water user agreement that you will execute with the City will define the flow and volume of water that will be available to each site The limiting factor is the storage tank The city will manage the system use based on the residual storage volume in the tank Over time, as total system flow demands increase, the residual pressure can be expected to decline at Ridgeline to the 60 - 65 psi range Additional pump(s) would then be required at the reclaimed water pump station Therefore, if I understand the information you need for des+gn+ng the trrtgatton system is how much residual pressure can be expected at the design flow rate Is there something more that you needy Please give me a call if you have any questions or need additional information I will follow this up with a written report with specifics of the calculations But hopefully this will address your immediate needs Please let me know if you need more Tom Skillings-Connolly, Inc Thomas E Sklllings, P E President Office (360) 491-3399 Direct (360) 455-3131 www sk/Ilmgs com This email (and or documents accompanying it) may contain confidential mformatwn befongmg to a sender, which is protected by the consultant client prrvllege The information Is Intended only for the use of the individual or entity named above If you are not the intended reciDlent, you are hereby notified that any disclosure, copying, distribution, or the taking of any action in reliance on the contents of this information is strictly prohibited If you received this email in error, please notify the sender immediately and delete the documents from your computer From Stan Zielinski [mallto Stan@erlcksonmcgovern com] Sent• Monday, February 27, 2006 5 38 AM To tskillings@skillings com Cc Stephanie Ray, dave@wdglnc com, Rocky Birkland, ray@ericksonmcgovern com, John Erickson Sub~ect• RE Minutes 9/26 meeting Tom, Just to follow up on our conversation on Tuesday with Dave Andrews, at Ridgeline MS (formerly known as YJHS), it's been 6 months since we started planning on using reclaimed water Now we are now behind the eight ball to the point where the unresolved irrigation issues could potentially cause a delay In construction You received the latest round of information you requested from Dave Andrews (see attached) on Thursday 2/23/06 I asked if he got a timeline from you of when we could expect information back from you so we can make 3/10/2006 ~, ~ r Page 3 of 3 necessary adjustments to our irrigation design in time to get it priced approved, ordered and installed prior to school starting in another 6 months Can we get a timeline on when we can have a decision on the irrigation system Also, please give us a status of the City's irrigation design for bringing the reclaimed water up Mtll Road to the NE corner of Mill Pond sites This could also prove to be a critical path item if it is not on schedule to be installed by April Thanks, Stan Zielinski From Stephanie Ray [madto stephanier@ci yelm wa us] Sent Friday, September 30, 2005 8 21 AM To bob@jwmorissette com, dave@wdginc com, Grant Beck, ~img@ci yelm wa us, Rocky Birkland, Stan@EricksonMcGovern com, Tim Peterson Subject Minutes 9/26 meeting FYI 3/10/2006 Page 1 of 3 I~ct.3 E~7z[ r~ ~.~' Jim Gibson From Stephanie Ray Sent Friday, March 10, 2006 11 29 AM To Jim Gibson Subtect FW Ridgeline Irrigation system FYI Steph From Tom Skillings [mailto tskillings@skillings com] Sent Tuesday, October 25, 2005 3 24 PM To 'stan', Stephanie Ray Cc 'Bob', 'Rocky Birkland', 'Dave Andrews', scoff@Iwmorrissette com, Amanda Heye Subject RE Ridgeline Irrigation system Bob, Stan We have finished our analysis of the calculated pressure anticipated at the elementary school property line Here is a summary for your information What we know or assumed . The elevation at the property line as provided by Bob T is 357 . The reclaimed water pump station, minimum water elevation is 329 0 . The pump station consist of two tockey pumps and two line-shaft turbines . The line shaft turbines are equipped with variable frequency drives that ad]ust speed to maintain a downstream pressure of 90 -105 psi Due to the lag time for reaction to ramp up to speed, there is a delay of up to 120 seconds when the line pressure can drop to 65 psi, but only for a short period . We modeled the system as if the supply was producing a constant head of 85 psi . We assumed there were other concurrent uses on the system amounting to 100 gpm in the subject 4" pipe and 200 gpm for other uses off of the 12" line . The school's irrigation system would have a flow that did not exceed 40 gpm *~` Conclusions . The residual pressure at the right of way Ime off of MIII Road, elevation 357 will be approximately 68 psi It can fall as low as 59 psi for short periods of time, but should come back up to 65 - 70 psi as the pump motors ramp up their speed ***Caution . When the City of Yelm negotiates the reclaimed water User's Agreement, the allowable flow will be limited to a set value I do not have the exact allowable gallons per minute that the school will be permitted to use on this site I have assumed 40 gpm for calculation purposes It may be lower . If you decide to install a booster pump station, you should also consider a flow control valve in the system I can not tell you today what the set point on the valve will be until the Reclaimed Water User's Agreement is finalized I hope this helps you get started with your onsite design, it should be pretty close 3/10/2006 Page 2 of 3 If you have any questions, please glue me a call Skdlmgs-Connolly, Inc Thomas E Skillings, P E President Office (360) 491-3399 Direct (360) 455-3131 www skdhngs com This email (and or documents accompanying it) may contain confidential information belonging to a sender, which is protected by the consultant client privilege The information is intended only for the use of the individual or entity named above If you are not the intended recipient, you are hereby notified that any disclosure, copying, distribution, or the taking of any action in reliance on the contents of this information is strictly prohibited [f you received this email in error, please notify the sender immediately and delete the documents from your computer From Stan [mailto stan@ericksonmcgovern com] Sent Monday, October 24, 2005 3 56 PM To Tom Skdlmgs Cc 'Bob', 'Rocky Birkland', 'Dave Andrews', scoff@Jwmorrissette com Subject FW Ridgeline Irrigation system Toms Any word on the protected operating water pressure of the reclaimed water system at Mlll Pond Intermediate School/Ridgeline Middle School site It costs the school district more each day we don't have the reclaimed system designed since the water system is being constructed at Ridgeline as we speak Thanks, Stan From Bob [mailto bob@Jwmorrissette com] Sent.
