AASHTO M-288 (AASHTO 2010) PROVIDES GUIDANCE FOR SELECTION OF GEOTEXTILES SPECIFICALLY FOR SEPARATION AND DRAINAGE APPLICATIONS. THE GEOTEXTILE MUST PASS WATER AT A GREATER RATE THAN THE SUBGRADE SOILS (0.5 INCHES/HR) AND APPARENT OPENING SIZE OF 0.25 M) MAX. REFER TO THE REPORT PREPARED BY GEORESOURCES, LLC FOR FURTHER GEOTECHNICAL AND PAVEMENT RECOMMENDATIONS _"GEOTECHNICAL CONSULTATION LETTER: POROUS PAVEMENT FOR THE SLAVIC CHRISTIAN CENTER" DATED: OCTOBER 22, 2013 CONTACT. BRAD P. BIGGERSTAFF, LEG & DANA C. BIGGERSTAFF, P.E. OFFICE: 253-896-1011 FAX: 253-896-2633 1. SUBGRADE SHALL BE SCARIFIED PRIOR TO PLACEMENT OF NON -WOVEN GEOTEXTILE AND FINAL GRADING. FINAL GRADING SHOULD BE COMPLETED BY MACHINERY OPERATING ON A PRELIMINARY SUBGRADE THAT IS AT LEAST 12 INCHES HIGHER THAN FINAL GRADE OR STRUCTURES TO DISTRIBUTE EQUIPMENT LOAD (e.g., STEEL PLATES OR AGGREGATE BASE MATERIAL). FINAL EXCAVATION THEN PROCEEDS AS MACHINERY IS PULLING BACK AND TRAVELING ON PRELIMINARY GRADE AS FINAL GRADE IS EXCAVATED. 2. TO PREVENT COMPACTION WHEN INSTALLING THE AGGREGATE BASE, THE FOLLOWING STEPS (BACK -DUMPING) SHOULD BE FOLLOWED: (1) - THE AGGREGATE DISCHARGE BASE IS DUMPED ONTO THE SUBGRADE FROM THE EDGE OF THE INSTALLATION AND AGGREGATE IS THEN PUSHED OUT ONTO THE SUBGRADE. (2) - TRUCKS THEN DUMP SUBSEQUENT LOADS FROM ON TOP OF THE AGGREGATE BASE AS THE INSTALLATION PROGRESSES. 3. AVOID SUBGRADE PREPARATION DURING THE WET SEASON (SOIL COMPACTION INCREASES SIGNIFICANTLY IS SOIL IS WET). 4. IF MACHINERY (RECOMMENDED LGP EQUIPMENT) MUST ACCESS THE FINAL GRADE, LIMIT THE ACCESS TO A SPECIFIC TRAVEL WAY THAT CAN BE TILLED BEFORE APPLICATION OF THE BASE AGGREGATE OR PLACE HEAVY STEEL PLATES ON SUBGRADE AND LIMIT TRAFFIC TO THE PROTECTIVE COVER. 5. NOTE: ALLOWING HEAVY MACHINERY ON PERMEABLE PAVING SUBGRADES DURING WET OR SATURATED CONDITIONS WILL RESULT IN DEEP COMPACTION (OFTEN 3 FEET) AND CANNOT BE COMPENSATED FOR BY SHALLOW TILLING OR RIPPING SOIL. } f s END ROAD IMPROVEMENTS STA, 2+53.16 TOP 203.0 -� ....- - TOE ZD1.0 - 27' RIGHT OF WAY DEDICATION TOP 209.2-� TOE 203.5 /77/// TOP 209.2 O TOE 203.3 EX.

APPROPRIATE DESIGN, CONSTRUCTION AND MAINTENANCE MEASURES WILL BE REQUIRED TO ENSURE THE INFILTRATION RATE CAN BE EFFECTIVELY MAINTAINED OVER TIME. IT SHOULD BE NOTED THAT SPECIAL CARE IS REQUIRED DURING THE GRADING AND CONSTRUCTION PERIODS TO AVOID FINE SEDIMENT CONTAMINATION OF THE INFILTRATION SYSTEM. THIS MAY BE ACCOMPLISHED BY USING AN ALTERNATIVE STORM WATER MANAGEMENT LOCATION DURING GRADING AND CONSTRUCTION ACTIVITIES. ALL CONTRACTORS WORKING ON THE SITE (BUILDERS AND SUBCONTRACTORS) SHOULD BE ADVISED TO AVOID "DIRTY" STORMWATER FLOWING TO THE SITE'S STORMWATER SYSTEM DURING CONSTRUCTION AND LANDSCAPING ACTIVITIES AT THE SITE. CONCRETE TRUCKS SHOULD NOT BE WASHED OR CLEANED ON-SITE. SUSPENDED SOLIDS COULD CLOG THE UNDERLYING SOIL AND REDUCE THE INFILTRATION RATE FOR THE SYSTEM. TO REDUCE POTENTIAL CLOGGING OF THE INFILTRATION SYSTEMS, THE INFILTRATION SYSTEM SHOULD NOT BE CONNECTED TO THE STORMWATER RUNOFF SYSTEM UNTIL AFTER CONSTRUCTION IS COMPLETE AND THE SITE AREA IS LANDSCAPED, PAVED OR OTHERWISE PROTECTED. TEMPORARY SYSTEMS MAY BE UTILIZED THROUGH CONSTRUCTION. PERIODIC SWEEPING OF THE PAVED AREAS WILL HELP EXTEND THE LIFE OF THE INFILTRATION SYSTEM.

PLANS FOR STRUCTURES SUCH AS BRIDGES, VAULTS, AND RETAINING WALLS REQUIRE A SEPARATE REVIEW AND APPROVAL BY THE CITY PRIOR TO CONSTRUCTION. 2. ROCKERIES ARE CONSIDERED TO BE A METHOD OF BANK STABILIZATION AND EROSION CONTROL. ROCKERIES SHALL NOT BE CONSTRUCTED TO SERVE AS RETAINING WALLS. ALL ROCKERIES IN CITY ROAD RIGHT-OF-WAY SHALL BE CONSTRUCTED IN ACCORDANCE WITH CITY STANDARDS. ROCKERIES OUTSIDE OF ROAD RIGHT-OF-WAY SHALL BE CONSTRUCTED IN ACCORDANCE WITH THE INTERNATIONAL BUILDING CODE.
