Jim Gibson, PE Date JE Gibson Engineering & Consulting 4 of 6 SECTION 1: PROJECT OVERVIEW Project Overview This Stormwater Site Plan was prepared for the Prairie Park Subdivision project that is located at 701 Prairie Park Lane SE. This report was prepared to comply with the minimum technical standards and requirements that are set forth in the most current version of the Department of Ecology Stormwater Management Manual for Western Washington (SWMMWW). The proposed site improvements include the following: Filling of the regional wet pond and infiltration pond. Construction of new mechanical pretreatment devices and below-grade infiltration trenches. Repaving of disturbed areas. The proposed project improvements will result in more than 5,000 ft2 of replaced impervious surface area. According to the SWMMWW, Minimum Requirements 1-9 need to be addressed. The following table summarizes how each requirement will be met. MINIMUM REQUIREMENT COMPLIANCE WITH MINIMUM REQUIREMENT #1 - Stormwater Site Plan The contents of this report and the enclosed plans are intended to satisfy this requirement. #2 - Construction SWPPP A Construction SWPPP has been prepared and is enclosed as an appendix. #3 - Source Control of Pollution If required, a Source Control Pollution Prevention Plan will be recorded against the property prior to certificate of occupancy. #4 - Drainage Path Preservation Preservation of the site’s previously established natural drainage paths will be maintained to the maximum extent practicable. #5 - Stormwater Management 100% on-site infiltration is proposed. The LID flow duration performance standard will be met for this project. #6 - Water Quality More than 5,000 ft2 of new/replaced impervious surface is proposed. A treatment train is proposed; pretreatment followed infiltration. #7 - Flow Control More than 10,000 ft2 of new/replaced impervious surface is proposed. 100% infiltration of stormwater runoff is proposed. #8 - Wetlands Protection According to the Thurston County Geodata mapping center, there are no on-site wetlands. #9 - Operation & Maintenance An Agreement to Maintain Stormwater facilities will be recorded against the property, if required. Table 1: Compliance with Minimum Technical Requirements SECTION 2: SITE CONDITIONS Existing Site Conditions The applicant is proposing to subdivide Thurston County TPN 64303700100, which is 13.84 acres in size, into 16 lots. The Prairie Park development was constructed in 2000. As a part of this project, a master stormwater facility was constructed which was designed to provide stormwater treatment and storage 5 of 6 for the entire Prairie Park site. Over the years, stormwater retrofit facilities were constructed for new phases of work (i.e., Prairie Hotel, Fay Fuller Building, Convention Center, etc.). These development sites are no longer connected to the master stormwater facility. Currently, the master stormwater facility provides water quality and flow control treatment for approximately 5.45 acres of the subject parcel. The applicant is proposing to fill the master stormwater facility for preparation of new lots. As a result, water quality and flow control facilities for the remaining 5.45 of tributary area will need to be provided prior to final plat. According to FEMA mapping, the property is outside of the flood zone. Once the subdivision is completed, each new tax parcel will need to comply with current water quality and flow control requirements at the time of proposed development. Soils Information Soils evaluation reports were prepared for the Prairie Park Commercial Development and Prairie Park Hotel Expansion projects in 2000 and 2008. An infiltration rate of 20 inches/hour was used for the design of stormwater facilities for projects. 10 inches/hour was used for the design of the proposed stormwater retrofit facilities for this project. SECTION 3: OFF-SITE ANALYSIS AND REPORT On-site generated stormwater runoff from the project area will be routed to on-site below-grade rock trench galleries. Off-site discharge is not proposed. Historic off-site drainage courses will not be altered. Consequently, downstream impacts are not anticipated. SECTION 4: PERMANENT STORMWATER CONTROL PLAN Summary Section The remaining 5.45 acres of tributary area that drains to the Prairie Park master stormwater facility is comprised of 5 sub-basins (A through E). Each sub-basin will be disconnected from the master stormwater facility and routed to an individual Aqua-Swirl and below-grade infiltration trench. The following tables identifies the different land-type designations and their respective areas for the on- site threshold discharge area. SUB-BASIN AREA (ACRES) Basin A – Clark Road south 0.88 Basin B – Clark Road north 0.97 Basin C – West Road SE ½ street 0.87 Basin D – cinema parking lot 1.61 Basin E – west parking lot 1.12 6 of 6 Performance Standards and Goals Basic Treatment is required for the proposed site improvements. The LID and Flow Control minimum performance standards also need to be met. A treatment-train consisting of pre-treatment and infiltration is proposed to satisfy the Basin Treatment requirements. 100% infiltration is proposed. The Flow Control and LID Flow Duration standards will be met. Water Quality System According to Volume III, Figure III-1.1, runoff treatment can be met through an infiltration facility that is preceded by pretreatment. An Aqua-Swirl mechanical treatment device is proposed for each sub-basin. See below table for sizing criteria of each Aqua-Swirl. SUB-BASIN WATER QUALITY FLOW RATE 100-YEAR PEAK FLOW RATE AQUA-SWIRL MODEL Basin A – Clark Road south 0.152 cfs <1.1 cfs AS-2 Basin B – Clark Road north 0.168 cfs <1.1 cfs AS-2 Basin C – West Road SE ½ street 0.151 cfs <1.1 cfs AS-2 Basin D – cinema parking lot 0.279 cfs <1.8 cfs AS-3 Basin E – west parking lot 0.194 cfs <1.8 cfs AS-3 Flow Control System The proposed below-grade infiltration trenches for each sub-basin have been designed per BMP T7.20. WWHM software was used to size each sub-basin facility. 100% of the runoff file from each sub-basin will infiltrate on-site. Each trench will be 12’ wide by 6’ deep (1’ of freeboard storage will be provided). Each trench will be installed with 2-12” runs of perforated stormwater pipe. Off-site discharge is not proposed. The WWHM reports are enclosed as an appendix. SUB-BASIN INFILTRATION TRENCH DIMENSIONS Basin A – Clark Road south 12’ wide x 6’ deep x 110’ long Basin B – Clark Road north 12’ wide x 6’ deep x 120’ long Basin C – West Road SE ½ street 12’ wide x 6’ deep x 110’ long Basin D – cinema parking lot 12’ wide x 6’ deep x 195’ long Basin E – west parking lot 12’ wide x 6’ deep x 140’ long 7 of 6 SECTION 5: PERMITS Civil Plan Review approval will need to be secured from the City of Yelm. SECTION 6: CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN A Construction Stormwater Pollution Prevention Plan will be prepared at a later date.

PE P"NELL ENGINEERING recommended in the vicinity of test pit #3 & #4 due to the presence of water table indicators in the soil profile and the general unsuitability of the upper horizon soils. 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 properly 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 to the practice of soils science, and to be suitable for its intended use. tY+S:i4,ali SIGNED: DATE: IU I (E IOt% �' C�! fr �;'1,. fiey,�;:..\'e' SOIL EVALUATION REPORT FORM 2: SOIL LOG INFORMATION PROJECT TITLE: Prairie Park Hotel Expansion SHEET: 2 OF 6 PROJECT NO.:07129-Rl DATE: 7/13/07 PREPARED BY: William Parnell, P.E.

Appendix V — Soil Evaluations SOIL EVALUATION REPORT FORM 1: GENERAL SITE INFORMATION PROJECT TITLE: Prairie Park SHEET: 1 OF 2 PROJECT NO.:00007 DATE: 1/10/00 PREPARED BY William W. Parnell, P.E. 1. SITE ADDRESS OR LEGAL DESCRIPTION: 700 Prairie Park Lane Yelm, WA 98597 2. PROJECT DESCRIPTION: To commercially develop an 18.2 acre site to support the following existing and proposed buildings and their associated utilities, roadwork and landscaping. Building A 8 Screen Cinema 26,000 sq. feet Building B Retail Space 8,000 sq. feet Office Space 3,000 sq. feet Restaurant 5.000 sq. feet Apartments 6,000 sq. feet Building C Library 6,000 sq. feet Building D Retail 2,500 sq. feet Building E Retail 5,000 sq. feet Building F Existing Conference 6,000 sq. feet Building G Hotel Expansion 24 rooms Building H Existing Hotel 24 rooms Restaurant 5,000 sq. feet Building I Office 7,500 sq, feet 3. SITE DESCRIPTION: The project site is currently partially developed. An existing bank building, office conference center, and hotel reside on the south central portion of this site. Residential dwellings occupy a small area located at the northwest and the southwest corner of the site. The remaining area within the scope of this project is used as a hay field. The topography along the northern property boundary is relatively flat. The western portion of this site is gently rolling. A natural broad swale traverses the site in a west to east direction and acts as a natural basin for the existing undeveloped site stormwater runoff. There were no physical indications that standing surface water is ever present within the confines of the Swale, The site is bounded by West Road SE to the north, 1031d Avenue SE to the southeast, Yelm Avenue (SR 507) to the south, and the Yelm Alternative School grounds to the west. The onsite soils were formed on a terrace out of glacial outwash. 4. SUMMARY OF SOILS WORK PERFORMED: Eight test pits were excavated by backhoe and ranged in depth from 72" — 156" below existing grade. Soils beyond four feet were visually and physically inspected by sampling through the use of a long handled garden hoe and/or inspecting backhoe tailings. Double Ring infiltration tests were completed for test pits #1, 2, 4, 5, and 7. Test pit #7 did not pass the 10 minute pre -test due to fines in the soils texture and was subsequently pre-soaked for 4 hours. Test pit #1 failed the pre -test but failure was due to the density of the soil, not to the amount of fines present in the soils texture. Pre-soaking was considered unnecessary and the double ring infiltration test was promptly completed. All other test pits passed the 10 minute pre -test and were subsequently tested. 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 appreciable distances from those soil test pits as located on the site plan map. 6. FINDINGS: The onsite soils for this project site were mapped by the Soil Conservation Service soils survey of Thurston County as a Spanaway (110) series and a Nisqually (74) series. All test pits generally confirmed these designations. Test pit #3, located at a low point in the broad swale did reveal a high winter water table at 62". None of the other test pits revealed any evidence of winter water table presence. Double Ring infiltration tests revealed infiltration rates ranging from 14 % inches/hour in test pit #7 to 144 inches/hour in lest pit #2. Tests were completed between 60" - 78" below existing ground surface in the C horizon soils. VA The Spanaway and Nisqually soils series are well drained with rapid permeability rates in the substratum soils. Drainage Infiltration facilities should be located in the C horizon soils and not the A horizon soils. The presence of a high winter water level in test pit #3 make this area unsuitable for drainage infiltration. The possibility of high winter water table exists for the other soil lest pits but was not evidenced at the time of soils logging. Drainage infiltration facilities installed no deeper than 96" below existing grades in the vicinity of soils test pits 1, 2, 4, 5, 6, 7, and 8 should not be impacted by winter water table concerns. Suggested infiltration rates are provided in the attached soils log data sheets. They are estimations of optimum infiltration rates for undisturbed soils. Site conditions after construction are disturbed and the receiving soils therefore may not infiltrate as readily as test results indicate. It is suggested to use conservative values when receiving soils have a high percentage of fine sand or finer material present, as was the case for test pit V. During construction, care must be taken to prevent erosion of exposed soils. Drainage facility infiltration surface areas must be properly protected from contamination by the fine grained upper horizon soils and from compaction by site construction activities. Soils not properly protected will cause 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 wo e complete an accurate within the bounds of uncertainly inherent to the practice of soil$ sciap and o be itable for its intended use.
