I(Jl Site Location The project site is located in the City of Yelm, Washington. Access to the site is from Yelm Ave, Longmire Street SE to the South and Berry Valley Road to the North. See Vicinity Map, Appendix 3. Project Overview The Proponent is proposing to grade those portions of Division 2 (9.9+/- acres) Tract A, B, C, D, and E in preparation for final construction of commercial activities. Construction will include clearing and grading of the site, installation of underground ~, storm drainage facilities sized for maximum impervious cover as identified in the Tahoma Terra Final Master Plan Development Guidelines and Erosion Control Measures. ~~ The development of "neighborhood commercial" was described in the Preliminary Drainage Report for the Tahoma Terra Master Plan development dated March 2005. The improvements will include appropriate erosion control measures as needed, grading, and storm drainage improvements. KPFF Consulting Engineers August 2006 Tahoma Terra Commercial Drainage Report KPFF Consulting Engineers All project contributing impervious areas are accounted as follows.

Impervious) Basins Impervious Pavement Impervious Sidewalk Impervious Driveways Roofs Disturbed Pervious Total TOTAL 5.28 0 0 1.65 2.97 9.90 Storm Drainage Improvements: It is assumed the completed project will create approximately 5.28 acres of new impervious roadways/parking facilities, 1.65 acres of roof area, and 2.97 acres disturbed pervious area proposed within the commercial parcel boundaries. Initial design proposed infiltration galleries on the commercial side of Tahoma Blvd. sized to infiltrate the contributing runoff from Tahoma Terra Residential. This report identifies these contributing basins and proposes new infiltration galleries and water quality measures sized accordingly and located on the Eastern side of Tahoma Blvd. within a separate storm drainage easement. Stormwater Treatment - "AquaShield Aqua-Swir1TM Model AS-2 CFD": Stormwater treatment will be obtained by utilization of a series of AquaShield AS-2 Aqua Swirl applications (approved by the Department of Ecology's "Emerging Technologies Program GULD for Pre-treatment) for the existing developed basins prior to discharge through infiltration trenches sized to infiltrate the 100 year-24 hour storm event. The Aqua-Swir1TM Concentrator Conveyance Flow Diversion System provides full treatment for the most contaminated "first flush," while the cleaner peak storm flow is diverted and channeled through the main conveyance pipe. Many regulatory agencies are establishing "water quality treatment flow rates" for their areas based on the initial movement of pollutants into the storm drainage system. The operation begins when Stormwater enters the Aqua-Swir1TM through a tangential inlet pipe which produces a circular (or vortex) flow pattern that causes contaminates to settle. Because stormwater flow is intermittent by nature, the Aqua-Swir1TM Concentrator retains water KPFF Consulting Engineers 3 August 2006 U Tahoma Terra Commercial Drainage Report KPFF Consultin~En aneers between storm events providing both "dynamic and quiescent" settling of inorganic solids. The dynamic settling occurs during each storm event, while the quiescent settling takes place ~( between successive storms. A combination of gravitational and hydrodynamic drag forces 1~ encourages the solids to drop out of the flow and migrate to the center of the chamber where velocities are the lowest, as shown from extensive CFD modeling. Water quality treatment for the future maximum impervious parking areas and travel ways for the commercial site will utilize a linear bio-filter strip 50 feet in length (off-line of the proposed ~ detention pond) providing water quality for the 6-mo, 24 hour storm event prior to discharging ' towards Thompson Creek. Final storm water drainage calculations are provided in Appendix 1. U See Appendix 2 for the Basins Map.

Runoff from the proposed roadways, sidewalk and driveways will sheet flow along the curb and gutter through series of catch basins. The catch basins will be connected with 12" storm pipe. The stormwater originally was intended to be discharged from the last catch basin into the proposed bio-infiltration swales. These bio-infiltration swales have been removed from the plans and it is proposed to convey this basin through the Aqua-Swirl treatment device prior to final dispersion within the proposed infiltration gallery. Basin K: Basin K total 3.77 ac includes 19 building lots, the 1.02 ac of impervious pavement, 0.24 ac impervious sidewalk, 0.22 ac impervious driveways, 0.65 ac roofs, and 1.64 ac disturbed pervious landscaping areas.

These bio- infiltration swales have been removed from the plans and it is proposed to convey this basin through the Aqua-Swirl treatment device prior to final dispersion within the proposed infiltration gallery. Roof Runoff (Basins C, K, L, M, N, O): Roof runoff from each residential lot will be tight lined to individual lot roof drywells. The drywells are designed per WS DOE 1992 Stormwater Manual based on an average roof size of ~ 1500 - 2000 square feet. For Soil Hydraulic Group "B" (Spanaway Gravelly Sandy Loam 110 series), the roof drywell bottom trench area sized to infiltrate 10-year, 24-hour storm. Im = 20in / hr. Fs = 2. P10 = 3 in. The each lot should have roof drywells at least 35' long x 3' wide x 3' ,s.-~ deep, or 50' long 2' wide x 3' deep. As a result of this, the roof areas for these existing basins have been removed from final quantity and quality sizing calculations for the commercial ~J portion of development. Commercial Basin: The Commercial properties encompass 9.90 acres of total site area. As outlined in the Tahoma Terra Final Master Plan Development Guidelines, maximum impervious surface allowed at final development is 70% of total site area. This amount was used in water quality and quantity sizing calculations for maximum build out. Area breakdown: 5.28 acres Pollution Generating Impervious surface, 1.65 acres Impervious Roof area, and 2.97 acres, disturbed pervious landscaping area. Off-line treatment is proposed with a 50' vegetative bio-filter strip post detention. Detention calculations allow for post developed release rates to be less then 50% of the 2-year 24 hour pre-developed Tahoma Terra Basin, and far less then the 10-year and 100- ~ year 24 hour event. Beyond this detention, discharge will occur through a level spreader providing uniform sheet flow across the off-line boiler strip prior to release towards Thompson Creek. ~,J 1 KPFF Consulting Engineers 5 August 2006 Tahoma Terra Commercial Draina e Re ort KPFF Consultin En ineers Section 2 -Existing Conditions The proposed site is relatively flat. The Commercial property located to the west of Phases 1 and 2 of Tahoma Terra Residential (Proposed Tahoma Blvd.) is rolling and hilly with broad valley areas gradually sloping to neighboring Thompson Creek. The site is accessible from Berry Valley Road to the north; Longmire Street SE binds the site to the south, residential to /~} the east and undeveloped property/creek buffer to the west. Vegetation consists of actively used agricultural pastured grasses, trees and under story plants. Thompson Creek, a low flow and sometimes intermittent stream that partially drains the wetlands located to the south of the proposed development is located to the West of the project site. This creek flows north into the Nisqually River near the Centralia City Light Electrical Power facility. In addition, there are some wetlands associated with Thompson Creek. These wetlands have been analyzed by previous studies and classified as Class II Wetlands and are being updated utilizing "Best Available Science" techniques. '~ The Tahoma Terra Phase I and II tributary basin to Thompson Creek in the pre-developed U condition is modeled as 47.65 acres of pasture with gradual slope. A majority of this area will be collected in an onsite conveyance system, treated through an Aqua-Swirl system prior to infiltration to groundwater and will no longer provide run-off to Thompson Creek. The SEPA determination of non-significance has been already issued by City of Yelm. This project is located in an aquifer sensitive area, according to the 1986 Thurston County Comprehensive Plan Map M-8. The site is within a 5-year and 10 year well head protection area. An Integrated Pest Management Plan will be developed for the project and provided to the DEVELOPER. Section 3 -Infiltration Rates/Soils Report The Soil Conservation Service (SCS) Soil Survey of Thurston County classifies the on-site soils as Spanaway Gravely Sandy Loam (110) series. William Parnell, PE Soil Engineer performed Geotechnical and Subsurface Exploration and Infiltrations Tests. His report, dated 19 January 2005 and additional soil logs on 23 June 2005, i is included in the Appendix 6. An infiltration rate of 20 inches per hour was used for design purposes. In addition, the infiltration galleries will be interconnected to provide for greater dispersal in an event clogging occurs and an emergency overflow will direct storm events larger then the 100-year, 24 hour event to Thompson Creek. (~ Section 4 -Wells and Septic Systems ,~.~} A site visit was made to determine if there were any wells or existing/abandoned septic systems ~ on the property. U+ There are three wells on the site or adjacent property that shall be abandoned according to WS DOE and Thurston County Department of Health standards. See Appendix 11 for wells p~1, location map. I~'`, Thurston County has no records of existing or abandoned septic systems on adjacent properties within 100 ft of the proposed infiltration facilities. Any septic systems encountered will be removed in accordance with Thurston County Department of Health standards. KPFF Consulting Engineers August 2006 l 6 Tahoma Terra Commercial Draina~port KPFF Consulting Engineers Water and sewer service will be provided by the City of Yelm at time of final building construction. Section 5 -Fuel Tanks A review of the DOE's Leaking Underground Storage Tanks (LUST) list did not indicate the f~' presence of any existing or abandoned fuel tanks on or near the project site. J~ Any fuel tanks found will be removed in accordance with WS DOE standards. ,~ Section 6 -Sub-Basin Description '~--+ The project site is located within the Yelm Creek Drainage Basin per the Thurston County (1 Comprehensive Map M-4. There is no significant off-site runoff to the project site. Runoff resulting from project build out will be equal to or less then pre-developed conditions. No handling of hazardous materials on this site is in forecast Section 7 -Analysis of the 100-Year Flood The site is found in FEMA Panel Number 53031 0001 A, which lies within Zone X and Zone A. This project does lie adjacent to and contain a stream onsite and has been identified as a 100 year flood hazard area. However, local or spot flooding, if it exists, usually is not shown on FEMA flood insurance rate maps, and especially when the source of flooding is related to logging, development, or drainage modifications since the date of the map. Although the Engineer is alert to the possibility of flooding from such sources, it cannot be warranted that all (((~~~ areas subject to flooding on or down gradient of the project site are represented on this map. See Appendix 4. Section 8 -Aesthetic Considerations for Facilities All disturbed pervious areas will be vegetated and landscaped at completion of construction. ~j Section 9 -Facility Sizing and Downstream Analysis Detailed storm drainage calculations are included in Appendix 1 of this report. All off-site ~ stormwater runoff will be treated, stored, and infiltrated on-site. On-site runoff will be treated by way of biofiltration strips located off-line (or downstream of detention) prior to discharge to neighboring Thompson Creek. The runoff flow rate predicted by Stormshed when modeled against the pre-developed basin concludes runoff will discharge at or below pre-developed condition flow rates with an appropriately sized combination orifice/weir control structure. Calculations for sizing of facilities are included in Appendix 1. Since all runoff will be at or below pre-developed rates, a downstream analysis was determined unnecessary. ~~ Section 10 -Covenants, Dedications and Easements ~-~ Drainage facilities including the pipe reaches, stormwater treatment mechanisms and infiltration galleries will require routine maintenance. A draft maintenance agreement between the owner and City of Yelm is included in Appendix 7, which will allow City access to the ~ facilities. City of Yelm will provide technical assistance at the owner's request. y~ KPFF Consulting Engineers 7 August 2006 ~`" Tahoma Terra Commercial Draana e Re ort KPFF Consultin En ineers ~~r J Section 11-Property Owners Association Articles of Incorporation As a condition of this project being "neighborhood commercial", the future commercial businesses will be part of the Tahoma Terra Home Owners Association. The Home Owners ~`~ Association and/or their representatives will perform maintenance of these private storm LJ drainage facilities. i KPFF Consulting Engineers 8 August 2006 ~~ U I(I~ ~J l~ ~ Part II Erosion Control Report ~1 Tahoma Terra Commercial Drainage Report KPFF Consulting En ineers y`~ PART II -EROSION CONTROL PLAN Section 7 -Construction Sequence And Procedure The proposed project will include an erosion control plan designed to contain silt and soil within the project boundaries during construction, and permanent erosion control post construction. Erosion/sedimentation control will be achieved by a combination of structurallvegetation cover measures and construction practices tailored to fit the site. Best Management Practices (BMP's) will be employed to properly clear and grade the site and to schedule construction activities. Before any construction begins on-site, erosion control facilities shall first be installed. The Contractor shall schedule apre-construction conference with the city, project engineer and construction-staking surveyor. The planned construction sequence is as follows: 1. Install rock construction entrances. Use 4" to 8" diameter spans with 12" minimum depth. U 2. Install filter fabric fencing and construction fence where appropriate. 3. Clear site (grubbing and rough grading). 4. Designate an area for washing of equipment and trucks to control sedimentation (~ runoff and eliminate any entry into the storm drainage systems ~ 5. During November 1 through March 31, all disturbed areas greater than 5,000 square feet that are to be left unworked for more than twelve (12) hours shall be stabilized by one of the following: mulch, sodding or plastic covering. 6. Provide catch basin inlet protection by installing silt socks under grates of all inlets to drainage system. 7. Install temporary sediment traps/ponds. 8. Landscape and/or seed all disturbed areas. 9. Maintain all erosion control facilities until the entire site is stabilized and silt runoff ceases. 10. After the site has been stabilized the infiltration trenches will be restored to designed conditions. Section 2 -Trapping Sediment Y ~ The soils on-site belong to the Spanaway group and have slight erosion potential according to jj~~1l the SCS. During construction, care must be taken to prevent erosion of exposed soils. Drainage facility infiltration surfaces must be properly protected from contamination by the fine-grained upper horizon soils and from compaction by site construction activities. Filter fabric fencing will be installed wherever runoff has the potential to impact downstream resources. This shall include the areas along downstream property lines as shown on the erosion control plan. During construction, the Contractor will also be required to install filter fabric fencing as needed, and as directed by the Engineer and/or the City of Yelm. Catch basin protection shall be provided by installing silt socks under grates of all inlets to drainage system. ` Stabilized construction entrances will be installed to prevent vehicles from tracking soil away from the site. If sediment is tracked off-site, it shall be swept or shoveled from paved surfaces on a daily basis, so that it is not washed into existing catch basins and/or grass ditches. All disturbed/exposed soils shall be covered with straw or mulch to prevent erosion in these ~ areas. The Contractor will not be allowed to leave disturbed areas greater than S,000sf (that are to be left unworked for more than twelve (12) hours) uncovered during the rainy season from November 1 through March 31. Mulch, sodding or plastic covering will be used to prevent l~ erosion in these areas. L1 ~l KPFF Consulting Engineers g August 2006 l~ Tahoma Terra Commercial Drainage Report KPFF Consulting En ineers ~ Section 3 -Permanent Erosion Control & Sife Restoration All disturbed areas will be hydroseeded, or landscaped with grass, shrubbery or trees in preparation of final construction activities consisting of paving and building construction to be completed at a later time and under separate cover. Section 4 -Geotechnical Analysis and Report There are no slopes exceeding 15-percent, therefore, a full geotechnical report was deemed ~ unnecessary for slope analysis. See appendix 6 for a complete soils description and CBR test ' !I results for gravel from the site by Geotechnical Testing Laboratory. ~~~------~~~ Section 5 -Inspection Sequence In addition to City inspections, the Project Engineer shall inspect the facilities related to stormwater treatment, erosion control, storage and conveyance during construction. At a minimum, the following items shall be inspected at the time specified: ~1 1.~ 1. The erosion control facilities should be inspected before the start of clearing and grading to ensure the following structures are in place: a. Construction Entrance C b. Filter Fabric Fences c. Catch Basin Inlet Protection 2. The conveyance systems will be inspected during the construction process to ensure the following are installed correctly: a. Grading for Drainage b. Catch Basins c. Conveyance piping d. Sediment ponds/traps ~ i 3. The permanent site restoration measures shall be inspected after landscaping is '~.~ completed. The erosion control and conveyance items listed above shall be inspected as soon as practical following every significant rainfall event (2-inches in a 24-hour period) that occurs during construction. A final inspection will be performed to check final grades, settings of control structures and all necessary findings to complete as-built drawings and to fulfill requirements of certification. The Soils Professional shall perform a sufficient number of infiltration tests and/or soil logs after construction to determine the facility will operate as designed. Section 6 -Control Of Pollutants Other Than Sediments Washout from trucks shall not be dumped into the storm drain, or onto soil and pavement, which carries stormwater runoff: It shall be dumped into a designated area to be later backfilled or hardened and broken up for disposal into a dumpster. The Contractor is required to designate a washdown area for equipment and trucks. Catch basins inlet protection and ,~ filter fabric fencing shall remain in place until construction on the site is complete. !~ !' ~ KPFF Consulting Engineers 10 August 2006 lU fry U ~' ~~ Part III Maintenance Plan Tahoma Terra Commerctial Dracna~e Report KPFF Consultin~gineers {J ~/ PART 111-MAINTENANCE PLAN ~J Section 7 -Required Maintenance The on-site storm drainage facilities will require occasional maintenance.

Please refer to your local representative for more information. 2) Many regulatory agencies are establishing "water quality treatment flow rates" for their areas based on the initial movement of pollutants into the storm drainage system. The treatment flow rate of the Aqua-SwirlT"'system is engineered to meet or exceed the local water quality treatment criteria. This "water qua/ity treatment flow rate" typically represents approximately 90% to 95% of the total annual runoff volume. The design and orientation of the Aqua-Swir1T"' generally entails some degree of customization.

SITE ADDRESS OR LEGAL DESCRIPTION: Longmire Street SE Yelm, WA 98597 2. PROJECT DESCRIPTION: Create a commercial and residential subdivision with all associated roadway, utility and landscaping improvements. 3. SITE DESCRIPTION: The eastern portion of the project site is currently developed as Tahoma Terra phase 1 and 2. The proposed commercial portion will occupy an area west of phase 1 and 2 and east of the 100 year floodline for Thompson Creek. Tahoma Terra phase 3-8 will occupy the western highlands adjacent to and west of Thompson Creek. The described project site is currently unoccupied. Site topography east of Thompson Creek is relatively flat with no distinguishing features. Site topography west of Thompson Creek generally consists of a gently sloping, rolling terrain over the central portion of the site. Steep slopes lie immediately west of Thompson Creek except in the area of the proposed access boulevard. Moderately steep to steep slopes occupy the southern fringes of the site, and sloping terrain is characteristic of the northern fringes of the site. Site vegetation consists of uncropped pasture grasses. The project site is bounded by Tahoma Terra phase 1 and 2 to the east, and undeveloped properly to the north, west and south. On-site soils are generally well drained and formed in glacial outwash. 4. SUMMARY OF SOILS WORK PERFORMED: Twenty-three test pits were excavated by trackhoe to a maximum depth of 252" below ebsting grade. Soils were inspected by entering and visually logging each test pit to a depth of four feet. Soils beyond four feet were inspected by examining backhoe tailings. Falling head percolation tests were completed in test pits #3A at 78" below the ebsting grade and #6A at 56". Double ring infiltration tests were completed in test pits #7A, #8A and #17A at depths of 12", 210° and 12" respectively. Soil log test pit data sheets, percolation and infiltration test results are included in this report. 5. ADDITIONAL SOILS WORK RECOMMENDED: Additional soils work should not be necessary unless drainage infiltration facilities are located outside the general area encompassed by the soil test pits. 6. FINDINGS: The National Resource Conservation Service (NRSC) of Thurston County mapped the on-site soils as a combination of Nisqually loamy fine sand (74), Everett gravelly sandy loam (33,34), and Yelm fine sandy loam (127). All test pits generally confirmed these designations as mapped with some variations. The area east of Thompson Creek was mapped by the NRSC as a Nisqually series but test pits were dominated by a Spanaway series profile. The Spanaway series is known to occupy small areas mapped as a Nisqually series. Test pits generally revealed gravelly fine sandy loam surface soils, overlying an extremely gravelly and cobbley coarse sand substratum. Substratum soils were moderately loose with few fines present. Winter water table was present in most test pits. The central portion and southwest comer of the site was mapped by the NRSC as a Yelm series. Test pits generally confirmed this designation in the central portion generally revealing a sandy loam stratum underlain by a loam, sandy loam and silt loam substratum. Considerable deviation from the NRSC mapping occur-ed in the southwest comer of the site. Several test pits immediately west of the southwest property line revealed soil profiles more closely resembling an Everett series and to a much lesser degree a Giles series. Winter water table was present in most test pits. The northwest, northeast (west of Thompson Creek) and southeast comers of the site were mapped by the NRSC as an Everett very gravelly sandy loam. However, previous soil loggings in the northwest and northeast revealed soils more similar to an Alderwood series generally profiling a sandy loam stratum underlain by ablation and basal till. The southeast comer of the site revealed soils but more closely resembling a Giles or Indianola series rather than an Everett series. Falling head percolation and double ring infiltration tests were completed revealing the following infiltration rates: Test pit #3A -144 in/hr, #6A -1080 in/hr, #7A - 3.75 in/hr, # 8A - 62.6 in/hr, #17A - 6.2 in/hr. Falling head percolation tests were completed utilizing a 6" diameter solid walled PVC pipe to I~ ~~ U U r"l 1~ I~ U n u ~` n~ v prevent sidewall collapse. 7. RECOMMENDATIONS: The Spanaway soil series is a somewhat excessively drained soil that formed in glacial outwash. Infiltration rates are generally rapid in the substratum soils. The substratum soils should be targeted for all drainage infiltration facilities. A prevalent winter water table presence requires consideration for all drainage facility designs. A design infiltration rate of 20 inlhr or less would be appropriate for all targeted C-horizon soils as recommended in the attached soil log information sheets. The Yelm soil series is a moderately well drained soil formed in glacial outwash. Infiltration rates are generally moderately rapid in the substratum soils. However, on-site soils contained an above average percentage of fines and soil density resulting in infiltration rates significantly less than average. A winter water table presence precludes utilizing the more coarse deeper horizon soils that generally yield more rapid infiltration rates. A design infiltration rate of 1.5 in/t-r or less would be appropriate for all targeted soils as recommended in the attached soil log information sheets. The Everett soil series is a somewhat excessively drained soil that formed in glacial outwash. Infiltration rates are generally rapid in the substratum soils. However, a winter water table presence in the southwest portion of the site precludes utilizing the more coarse, faster infiltrating substratum soils. A design infiltration rate of 2.0 in/hr or less would be appropriate for all targeted soils as recommended in the attached soil log information sheets. During construction, care must be taken to prevent erosion of exposed soils. Drainage facility infiltration surfaces must be properly protected from contamination by the fine-grained upper horizon soils and from compaction by site construction activities. Soils not property protected will cause drainage infiltration facilities to prematurely fail. I hereby certify that I prepared this report, and conducted or supervised the performance of related work. I certify that I am qualified to do this work. I represent my work to be complete an accurate within the bounds of uncertainty inherent t e practice of soils science, and to be suitable for its intended use. ~.
