The existing house has been razed to allow for the construction of a new home. North Stream runs westerly just north of the site (on the north side of Grandview Street). To mitigate the development of the site, an infiltration system will be installed to control the drainage runoff from the impervious surfaces. All on -site impervious surfaces are proposed to be collected and routed to the on -site infiltration system. A 6" overflow pipe will provide a discharge outlet if the infiltration system reaches capacity (to prevent flooding). Listed below is a summary of the infiltration trench design. Infiltration Trench Design: The on -site infiltration trench is to be constructed perthe City of Edmonds' standard practices. The length of the trench is dependant upon the measured infiltration rate of the native soils and the collection area conveyed to the individual trench. SCS soil survey designates the area soils as an Alderwood-Urban land complex (#5- type C) soil. SCS defines the Alderwood- Urban land complex as a mixture of multiple types of soils, including Alderwood, Everett and Norms soils. General soil characteristic can vary greatly due to the variation of multiple pockets of soil types (see attached description). Two test pits, in the area of the proposed infiltration trench were explored on -site. The soils found in the pits was medium sand (at a depth of about 2.0 feet below the .top duff). Thus, confirming the SCS description of an Everett (#18- type A) soil. Two test pit percolation trials were completed on the soil to determine the on -site percolation rate (see attached calculations). Using the City's design criteria (King County method), a required trench length was computed. A length of 50 feet of 4 feet deep, 4 feet wide trench was determined to fully infiltrate the 100-year design storm (P,00). See attached calculations.

M C!+o 1016 Grandview '� LSA No. 4647 A-1 1� Grading and Erosion Control: ' This project will require grading to raze the existing house and construct the proposed single family resident development. Standard erosion control measures are proposed to be used during construction. The primary erosion and sediment control BMP during construction will be proper soil stabilization methods. Exposed soils shall be stabilized by application of effective bmp's that ' protect the soil from the erosive forces of raindrops, flowing -water, and wind. Applicable practices include, but not limited to, temporary and permanent seeding, sodding, mulching, plastic covering, erosion control fabrics, matting, soil application of polyacrylamide (pam) , the early application of gravel base on areas to be paved, and dust control. The contractor shall select a soil stabilization method best suited for the particular situation. Stock piles must be stabilized and protected with sediment trapping measures. In addition, site containment of exposed soils shall be sustained by ' using silt fence barriers along the down -slope boundaries of the site's disturbance areas. See the site development plan for details. ' Estimated grading calculations: Min.imal project grading is expected due to the relatively flat site. The following grading quantity estimations were calculated using a computer modeling program within the AutoCAD computer drawing. The calculations are approximate. The quantities listed are for the permitting process only and should not be considered precise amounts for bidding purposes. The estimated grading quantities are: Approximate Fill: 100 CY Approximate Cut: 200 CY Conclusion: Included in the site development construction plans are specific grading and ' drainage improvement notes and details. With proper installation, maintenance and inspections of the proposed construction the project should have minimal impact to the surrounding environment. 1 ' Lovell-Sauerland and Associates Leif Helleren Construction, Inc.

Two on -site soil test pits were evaluated to determine the design infiltration rates of the soils on -site (see attached test pit logs). Both test pits contained a medium sand. An average rate of 18 in/hr will be used (see field tested infiltration rates). The following calculations size the proposed infiltration trench. Required Trench: L = [(0.054 x P,00 X AR) / (10 x IM)] / (trench surface area) -L = ?

Construction: Criteria • Trench Preparation -Excavated materials must be placed away from the trench sides to enhance trench wall stability. Care should also be taken to keep this material away from slopes, neighboring property, sidewalks and streets. It is recommended that this material be covered ' with plastic. (see Erosion/sediment control Criteria in Volume II). • Stone Aggregate Placement and Compaction - The stone aggregate should be placed in lifts and compacted using plate compactors. As a rule of thumb, a maximum loose lift thickness of 12 inches is recommended. The compaction process ensures geotextile conformity ' to the excavation sides, thereby reducing potential piping and geotextile clogging, and settlement problems. • Potential Contamination - Prevent natural or fill soils from intermixing with the stone aggregate. All contaminated stone aggregate must be removed and replaced with uncontaminated stone aggregate. • Overlapping and Covering -Following the stone aggregate placement, the geotextile must be folded over the stone aggregate to form a 12 inch minimum longitudinal overlap. When overlaps are required ' between rolls, the upstream roll should overlap a minimum of 2 feet over the downstream roll in order to provide a shingled effect. I 1 1 Voids behind Geotextile - Voids between the geotextile and excavation sides must be avoided. Removing boulders or other obstacles from the trench walls is one source of such voids. Natural soils should be placed in these voids at the most convenient time during construction to ensure geotextile conformity to the excavation sides. Soil piping, geotextile clogging, and possible surface subsidence will be avoided by this remedial process. Unstable Excavation Sites - Vertically excavated walls may be difficult to maintain in areas where the soil moisture is high or where soft or cohesionless soils predominate. Trapezoidal, rather than rectangular, cross -sections may be needed. Maintenance Criteria • Sediment buildup in the top foot of stone aggregate or the surface inlet should be monitored on the same schedule as the observation well. c ober 2004 olume — ydrologic Analysi arig",pontrol BMps-016 Grandview August 2 09 ��' '� LSA No. 4647 �� PERCOLATION RATE CALCULATIONS: Two soil investigation test holes were explored in the area of the proposed infiltration system.

October 2004 1016 Grandview LSA No.4647 R.1 L 1 1 SOIL SURVEY OF SNOHOMISH COUNTY AREA, WASHINGTON UNITED STATES DEPARTMENT OF AGRICULTURE, NATURAL RESOURCE CONSERVATION SERVICE (FORMALLY SCS- SOIL CONSERVATION SERVICE) Alderwood - Urban Land Complex, 2 to 8 percent slopes (soil # 5) This map unit is on till plains. Areas are irregular in shape and are 100 to 1,000 acres in size. The native vegetation is mainly conifers. Elevation is 50 to 550 feet. The average annual precipitation is about 40 inches, the average annual air temperature is about 50 degrees F, and the average frost -free season is 170 to 190 days. This unit is about 60 percent Alderwood gravelly sandy loam and about 25 percent Urban land. The components of this unit are so intricately intermingled that it was not practical to map them separately at the scale used. Included in the unit are small areas of McKenna and Norma soils and Terric Medisaprists in depressional areas and drainageways on plains. Also included are small areas of soils that are very shallow over a hardpan; small areas of Everett, Indianola, and Ragnar soils on terraces and outwash plains; and soils that have a stony and bouldery surface layer. Included areas make up about 15 percent of the total acreage. The Alderwood soil is moderately deep over a hardpan and is moderately well drained. It formed in glacial till. Typically, the surface layer is very dark grayish brown gravelly sandy loam about 7 inches thick. The upper part of the subsoil is dark yellowish brown and dark brown very gravelly sandy loam about 23 inches thick. The lower part is olive brown very gravelly sandyloam about 5 inches thick. A weakly cemented hardpan is at a depth of about 35 inches. Depth to the hardpan ranges from 20 to 40 inches. Permeability of the Alderwood soil is moderately rapid above the hardpan and very slow through it. Available water capacity is low. Effective rooting depth is 20 to 40 inches. Runoff is slow, and the hazard of water erosion is slight. A seasonal perched water table is at a depth of 18 to 36 inches from January to March. Urban land is areas that are covered by streets, buildings, parking lots, and other structures that obscure or alter the. soils so that identification is not possible. The Alderwood soil in this unit is used mainly for parks, building sites, lawns, gardens, and woodland. The main limitations of the Alderwood soil for homesites and septic tank absorption fields are the depth to the hardpan and the seasonal perched water table. Onsite waste disposal systems often fail or do not function properly during periods of high rainfall. Drainage is needed if buildings with basements and crawl spaces are ' constructed. Topsoil need to be stockpiled during site preparation and subsequently used to cover the exposed material. Additions of fertilizer and peat are desirable prior to seeding grass for lawns.

A) PRESERVE AS MUCH NATIVE VEGETATION AS POSSIBLE BE SURE TO OBSERVE CLEARING AND GRADING LIMITS, AND COMPLY WITH ALL CITY VEGETATION PRESERVATION AND STREAM/WETLAND SETBACK REQUIREMENTS. TIME THE CLEARING SO IT OCCURS NO SOONER THAN NECESSARY FOR SUBSEQUENT CONSTRUCTION ACTIVITIES. B) PROVIDE TEMPORARY VEGETATION/COVER AS NEEDED. EXAMPLES OF THIS INCLUDE TEMPORARY SEEDING/ HYDROSEEDING; MULCH, SUCH AS HAY STRAW, OR WOOD FIBER; MATS/BLANKETS, SUCH AS JUTE MAT EXCELSIOR WOVEN STRAW BLANKET; OR NETTING; PLASTIC SHEETING WITH ANCHORS. C) PROVIDE PERMANENT VEGETATION COVER AS SOON AS EARTHWORK IS COMPLETE (SEEDING OR HYDROSEEDING OR SODDING). II) CONTROL RUNOFF DURING CONSTRUCTION: REDUCE RUNOFF VELOCITIES. TECHNIQUES INCLUDE: VEGETATING EXPOSED SOILS AND DITCHES, RIPRAR CHEEK DAMS INCLUDING STRAW BALES, ROCKS, PEA GRAVEL BAGS, AND SAND BAGS, TERRACING OR CONTOURING THE SITE, AND FILTER FABRIC FENCING. III) INSTALL AND MAINTAIN SEDIMENT CONTROLS A) INSTALL SEDIMENT CONTROLS SUCH AS: 1) LOWER COST (NON -ENGINEERED), FILTER FABRIC FENCE, 'CHECK DAMS, ROCK BERMS, SEDIMENT TRAPS, AND CATCH BASINS AND DRAIN FILTERS 2) MODERATE COST (ENGINEERED), INTERCEPTING DITCHES, CUT-OFF TRENCHES, LEVEL SPREADER, AND GRADIENT TERRACING/CONTOURING. 3) HIGHER COST (ENGINEERED), SILTATION/SEDIMENTATION POND, GRASS -LINED SWALE OR CONSTRUCTED WETLAND. B) MAINTAIN SEDIMENT CONTROLS BY FREQUENT INSPECTION OF CONTROL FACILITIES TO MAKE SURE THEY ARE WORKING PROPERLY (TRAPPING SEDIMENT ON -SITE, WITH WATER LEAVING SITE CLEAR), AND REMOVING COLLECTED SEDIMENT AS NEEDED FROM SEDIMENT TRAPS. IV) KEEP FRESH CONCRETE MORTAR OUT OF STORM DRAINS AND STREAMS. A) USE DESIGNATED WASH -OUT AREAS B) TAKE CARE WHEN BUILDING CONCRETE AGGREGATE DRIVEWAYS MAKING SURE TO WASH OUT THE FINES TO THE SIDE, NOT DOWN THE DRIVEWAY. IF THE DRIVEWAY IS SLOPED, PLACE STRAW BALES AT THE BOTTOM OR DIVERT FLOW TO A SAFE SEDIMENT BASIN. C) NEVER WASH FRESH CONCRETE MORTAR INTO THE STORM DRAIN OR A STREAM. CALL BEFORE YOU DIG 1-800-424-5555 V) KEEP BUSINESS AND WORK AREAS CLEAN AND MAINTAIN CATCH BASINS. EXAMPLES INCLUDE. PICKING UP UTTER, SWEEPING SURFACES WHICH DRAIN TO STORK DRAIN, USING A TARP TO COVER THE GROUND WHEN SANDING TO CATCH CHIPS, CLEANING UP ALL WASTES AT THE WORK SITE, MAINTAINING CONSTRUCTION EQUIPMENT TO FIX ANY OIL LEAKS, INSTALLING AND MAINTAINING AN OIL/WATER SEPARATOR, COVERING ALL STOCK PILED MATERIALS, AND CLEANING CATCH BASINS. VI) COVER CONTAINERS AND MATERIALS. A) COVER ALL POTENTIALLY POLLUTING MATERIALS SUCH AS DUMPSTERS, WASTE CONTAINER DRUMS, TANKS, BOXES, CHEMICALS, PAINTS, SOLVENTS, STOCKPILES OF LUMBER, OTHER BUILDING MATERIAL, METAL PRODUCTS, TOP SOIL, AND LANDSCAPING MATERIALS. B) COVER ADEQUATELY BY DEVELOPING GOOD STORAGE AREAS THAT KEEP MATERIALS COVERED SO POLLUTANTS CAN'T WASH AWAY DURNG RAIN OR SNOW. Vil) PREPARE FOR AND CLEAN UP SPILLS. A) THERE ARE THREE OVERALL PRACTICES TO MINIMIZE POLLUTION FROM SPILLS: 1) HANDLE MATERIALS CAREFULLY TO AVOID SPILLS AND LEAKS, 2) PREPARE A CLEAN UP PLAN, AND 3) IMMEDIATELY CLEAN UP ANY SPILLS WHEN PREPARING A CLEAN UP PLAN MAKE SURE TO: A) ESTABLISH WHO TO NOTIFY IN THE EVENT OF A SPILL, B) PROVIDE SPECIFIC CLEAN UP INSTRUCTIONS, C) ASSIGN A PERSON TO BE IN CHARGE OF CLEAN UP, AND D) PREPARE SPILL CONTAINMENT AND CLEAN UP KITS WHICH ARE EASY TO REACH AND USE REMEMBER TO CLEAN UP SPILLS IMMEDIATELY, AND OBSERVE CLEAN UP PLANS AND SAFETY REQUIREMENTS. IF THERE ISN'T A PLAN, TAKE THE FOLLOWING STEPS: 1) STOP OR ISOLATE THE SOURCE OF THE SPILL, 2) IF THERE'S A CHANCE THE SPILL COULD ENTER THE STORM DRAIN OR SEWER, CLOSE DRAIN INLET AND DIVERT ANY INCOMING WATER. 3) COVER THE SPILL WITH ABSORBENT MATERIAL(S) THAT CAN BE EASILY SWEPT OR PICKED UP SUCH AS KITTY UTTER, SAWDUST, OR VERMICULITE (MAKE SURE THAT MATERIALS USED FOR HAZARDOUS WASTE CLEAN UP ARE TREATED AS HAZARDOUS WASTE FOR DISPOSAL), AND 4) REPORT SPILLS TO CITY OF EDMONDS ENGINEERING DAISION, HYDRAULICS ENGINEER AT 425-771-0220: OR FOR LARGE SPILLS, CONTACT DEPARTMENT OF ECOLOGY AT 425-649-7000. V111) DISPOSE OF WASTES PROPERLY. PROPER WASTE DISPOSAL DEPENDS GV BOTH THE PROPERTIES AND THE AMOUNT OF THE WASTE TO DISPOSE OF WASTE. 1) DEN71FY IF IT IS HAZARDOUS, 2) ESTIMATE THE AMOUNT IN POUNDS, 3) DETERMINE THE DISPOSAL METHOD, AND 4) IF NECESSARY, CONTACT A HAZARDOUS WASTE SERVICE. THIS IS A VERY BROAD SUBJECT AND IF YOU HAVE ANY QUESTIONS ABOUT WASTE DISPOSAL CONTACT THE CITY OF EDMONDS RECYCLING COORDINATOR AT 425-771-0235, OR THE SNOHOMISH COUNTY HOUSEHOLD HAZARDOUS WASTE DISPOSAL STA71ON AT 425-388-6050. IX) MINIMIZE WASTE WASTES CAN BE MINIMIZED THROUGH GOOD HOUSEKEEPING, SEPARATING DIFFERENT WASTES, SUBSTITUTING NON -HAZARDOUS MATERIALS IN THE PLACE OF HAZARDOUS ONES, AND MAINTAINING PRODUCTS AND CONSTRUCTION EQUIPMENT REDUCING WASTES REDUCES POTENTIAL SOURCES OF POLLUTANTS TO THE DRAINAGE SYSTEM AND ALSO PRESERVES NATURAL RESOURCES. THE FOLLOWING ARE A FEW IDEAS: 1) USE SOLVENTS MORE THAN ONCE, 2) BUY THE LEAST TOXIC PRODUCTS AVAILABLE, 3) BUY ONLY WHAT YOU NEED AND USE ONLY WHAT IS NEEDED, 4) PURCHASE PRODUCTS THAT LAST LONGER (BETTER QUALITY), AND 5) SEE IF OTHERS CAN USE YOUR WASTE (USE THE SERVICES OF THE INDUSTRIAL MATERIALS EXCHANGE 206-296-4899), FOR MORE INFORMATION CONTACT THE CITY OF EDMONDS RECYCLING COORDINATOR AT 425-771-0235. X) RECYCLE UNWANTED MATERIALS. UNWANTED MATERIALS PRODUCED AT CONSTRUCTION SITES CAN OFTEN BE RECYCLED, AT LESS COST THAN CONVEN71ONAL DISPOSAL METHODS THE CITY HAS RECYCLING GUIDES AVAILABLE REGARDING CONSTRUCTION, DEMOLITION, AND LAND CLEARING (COL) ACTIVITIES. THE RECYCLING GUIDE LISTS SITES THAT ACCEPT CDL MATERIALS, AND OUTLINES HOW TO SE -UP WORKSITE RECYCLING. OTHER WAYS TO MAKE RECYCLING WORK ARE. 1) PURCHASE RECYCLED PRODUCTS, 2) SEPARATE WASTES, 3) AVOID PHENOL, 4) KEEP RECEIPTS, AND 5) RECYCLE WHAT YOU CAN. XI) PRESERVE/ENHANCE STREAMS, WETLANDS, AND ADJACENT VEGETATION. PROTECT STREAMS AND WETLANDS, REMEMBER, STREAM AND WETLAND PROTECTION IS REQUIRED BY CITY OF EDMONDS CODES. CONTACT CITY OF EDMONDS, PLANNING DIVISION AT 425-771-0220 FOR MORE INFORMATION. Xil) EDUCATE EMPLOYEES AND CUSTOMERS. PARTICIPATE IN WORKSHOPS, COURSES, AND KNOWLEDGE TRANSFER. CONDUCT ANNUAL WATER QUALITY TRAINING SESSIONS FOR ALL EMPLOYEES INCLUDE WATER QUALITY TRAINING IN NEW -EMPLOYEE ORIENTATIONS AND IN WRITTEN PROCEDURES MAKE SURE CUSTOMERS ARE AWARE OF BMPS, AND EXPLAIN BMPS TO PEER BUSINESSES. REMEMBER, WATER QUALITY 1S THE RESPONSIBILITY OF EVERYONE MANY OF THE BMPS DELINEATED ABOVE ARE DESCRIBED IN MORE DETAIL IN THE WASHINGTON DEPARTMENT OF ECOLOGY STORM WATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN. NOT SURE IF A PARTICULAR SUBSTANCE IS HAZARDOUS? UNCERTAIN OF HOW TO DISPOSE OF SOMETHING? CALL THE CITY OF EDMONDS RECYCLING COORDINATOR AT 425-771-0235 BETWEEN 8AM AND 5PM, MONDAY THROUGH FRIDAY. IF IT IS AFTER BUSINESS HOURS, PLACE THE SUBSTANCE IN A SEALED CONTAINER, LABEL IT AND STORE IT IN A SAFE PLACE WHERE NO ONE CAN TOUCH IT. CALL THE RECYCLING COORDINATOR THE NEXT BUSINESS DAY TO HELP GET YOU THE INFORMATION YOU NEED.
