The plans are not very legible and I am having a hard time reading some of the notes and call outs. Please provide us with more legible plan pages for the most comprehensive review. 2. Per the energy credits selected for this home there are a few things that need clarity. Option 1.4 requires wall insulation of R-21 plus R-4 ci on the exterior-this is not indicated on the plan. Option 2.2 requires a heat recovery system that is not noted on the plan. Option 5.3 requires a gas or propane water heater and the specs and notes on the plan indicate electric water heater to be used. Please clarify your energy credits and have all necessary details on the plans. 3. In relation to the water heater; if a propane water heater is to be used then you will also need to add the propane tank onto the plumbing and mechanical application and show where it is to be located. 4. 1 do not see a second floor plan layout page included in this plan set at all. Please provide floor plan for second floor 5. Crawl space ventilation is not noted or indicated on the plans. Please add. 6. The garage is required to have a heat detector installed and currently the plan does not reflect that. Please add 7. The window sizes as well as the header sizes are not indicated on the plan and if they are in the notes I am unable to read them. Please add this information onto the plans. 8. The insulation values are also not shown on the plans on the cross sections. Please add. Once these items are complete I can begin to do a full plan review. Please let me know if you have any questions.

Flaggw•ood Lane, Union,WA 98582,Parcel#: 32104-58-0001 Introduction This geotechnical engineer, licensed as a professional civil engineer in the state Washington, visited the above site on Monday August 22. 2022 to do a site investigation of the general topography, the existing drainage system as well as the insitu soils. The primary purpose is to prepare a stormwater management plan per the 1992 Stormwater Technical Manual for the Puget Sound basin prepared by the Washington State Department of Ecology. '['his will ensure that the proposed single-family residential (SFR) site will be constructed in such a way as to retain any stormwater runofT on the site to the extent possible and minimize water and sediment to adjacent properties and public roads. While at the site,this soils engineer took digital color photographs of the existing perk holes that were dug for the proposed septic drainfield and checked to see if there was any evidence of any standing water at the bottom of these 4-feet plus deep perk holes. No evidence of standing water w,as observed. This stormwater management plan will describe in detail how- surface water runoff will he taken care ofonsite with little to no impact on adjacent properties or on the public roads. Site Description The location of this proposed single family residential site is located within the Alderbrook development in Union. VIVA. Most of the area is already well developed with an existing, system of roads and drainage ditches along the sides of the roads for stormwater runoff mitigation from these roads. A well-groomed golf course is also located within this development with well maintained homes surrounding this course. The proposed building site is located on the uphill side of this development where a number of single-family homes have already been built. In general,this is a well developed, well maintained residential community. in general. this corner lot is mostly level and flat with no local channels or streams in the area. An entrance has been provided on the south side of this small parcel with a drainage ditch located on the south side of the parcel to collect any surface water runoff from the public roads. Typically, this existing rock lined drainage ditch is to control runoff from East Manzanita Drive to the north, Vine Maple Lane to the west, as well as East Flagwood Lane on the south side of the 1018 E.Wishkah St., Aberdeen, Washington 98520-2937 (360)310-02710 c,(360)289-0958 b,(800)590-0958 Toll Free SMorted,aol.com Aug. 24. 2022 Page 2 of 3 MET Engineering, PLLC property. Existing catchbasins were observed at the NW corner a, well as dte SW corner of this small parcel as shown in the attached site plan. Small Parcel Requirements According to the Mason County Stonnwater Management Manual which references the Washington State Department of Ecology's 1992 Stormwater Manual, a small parcel has been defined as the creation or addition of less than two thousand square feet of impervious surface area and that disturbing activities is less than one acre. This proposed single family residence project satisfies these two requirements for a small parcel and. therefore, the following requirement apply. Small Parcel Requirement#1: Construct Access Road. Construction vehicle access shall be, whenever possible. limited to one route. Access points shall be stabilized to minimize the tracked sediment onto public roads. Wherever construction vehicle access routes intersect paved roads, provisions must be made to minimize the transport of sediment (mud) onto the paved roads. If sediment is transported onto a road surface creating a hazard, the roads shall be cleaned immediately, and thoroughly cleaned at the end of each day. Sediment shall be removed from roads by shoveling or sweeping and be transported to a controlled sediment disposal area. Street washing shall be allowed only after sediment is removed in this manner. Reference is made to Appendix 1: BMP E2.10 Stabilize Construction Entrance and Tire Wash. Small Parcel Requirement #2: Stabilization of Potentially Erodible Denuded Areas. To stabilize soils, all exposed and unworked soils with erosion potential shall be stabilized by suitable application of 13MPs, including but not limited to sod or other vegetative, plastic covering, mulching, or application of ground base on areas to be paved. All BMPs shall be selected. designed. and maintained in accordance with this Stonnwater Plan. From October I through April 30, no soils shall remain exposed for more than two days. From May 1 through September 30, no soils shall remain exposed by more than ;:even days. Small Parcel Requirement#3: Protection of Adjacent Properties. Adjacent properties shall be protected from sediment deposition by appropriate use of vegetative buffer strips, sediment barriers or filters. dikes or mulching, or by a combination of these measures and other appropriate BMPs. Reference is made to Appendix If: Sediment Retention BMP E3.10: Filter Fence. Small Parcel Requirement#4: Maintenance. All erosion and sediment control BMPs shall be regularly inspected and maintained by the owner or authorized agent to ensure continued performance of their intended function. An inspection O&M log-book shall be maintained by the owner, or their representative, to record and document the existing conditions of the BMPs on a semi-annual basis starting around October I which normally is the beginning of the rainy season and the second BMP inspection on around April 30 when the rainy season begins to wind down. Small Parcel Requirement #5: Other BMPs. As required by the director. other appropriate BMPs to mitigate the effects of increased runoff shall be applied. Reference is made to Appendix iIi: BMP E3.30: Storm Drain Inlet Protection, The two catchbasins on this site will be protected by this BMP by installing a geotextile filter protective sediment barrier around both 1018 E.

This will prevent sediment and soils from entering the drainage systems. Once the site has been sodded or grassed over with a lawn this BMP can be removed from around both MS. Conclusions and Recommendations It is the conclusion of this geotechnical engineer that the stormwater management practices per the 1992 Washington State Technical Management Manual for the Puget Sound Basin in the form of BMI-'s have been incorporated into this single-family residential project. To minimize surface water rtmofr it is recommended that all roof downspouts be tightlined into a 4" diameter perforated PVC' pipe that is at least 15-feet long extending away from the residence and away from the septic drainfield and the reserve area located north of the proposed residence as indicated in the attached site plan. It is also recommended that sod or grass he placed over the appropriate topsoil. once the building phase has been nearly completed. This will help to absorb much of the surface water runoff from the roof as well as the driveway and sidewalks. The primary intent of this Stonnwater Management Plan is to ensure that surface water runoff is mostly maintained onsite to minimize runoff onto adjacent properties and public roads that are located on the north. south. and west side of this corner parcel.

A-p- cPbaD 1 mil__ II-5.6.1 �BMP E2.10: Stabilized Construction Entrance and Tire Wash Code: E Symbol: Definition A temporary stone-stabilized pad located at points of vehicular ingress and egress on a construction site. Purpose To reduce the amount of mud, dirt, rocks, etc. transported onto public roads by motor vehicles or runoff by constructing a stabilized pad of rock spalls at entrances to construction sites and washing of tires during egress. Conditions where Practice Applies • Whenever traffic will be leaving a construction site and moving directly onto a public road or other paved areas. Advantages • Mud on vehicle tires is significantly reduced which avoids hazards caused by depositing mud on the public roadway. • Sediment, which is otherwise contained on the construction site, does not enter stormwater runoff elsewhere. Planning Considerations Construction entrances provide an area where mud can be removed from vehicle tires before they enter a public road. If the action of the vehicle traveling over the gravel pad is not sufficient to remove the majority of the mud, .then the tires must be washed before the vehicle enters a public road. If washing is used, provisions must be made to intercept the wash water and trap the sediment before it is carried off-site. Construction entrances should be used in conjunction with the stabilization of construction roads to reduce the amount of mud picked up by vehicles. It is important to note that this BHP will only be effective if sediment control is used throughout the rest of the construction site. Design Cgiteria • Material should be quarry spalls (where feasible), 4 inches to 8 inches size. • The rock pad shall be at least 12 inches thick and 100 feet in length for sites more than 1 acre; and may be reduced to 50 feet in length for sites less than 1 acre. • A filter fabric fence (see BMP E3.10) should be installed down-gradient from the construction entrance in order to contain any sediment-laden runoff from the entrance. Width shall be the full width of the vehicle ingress and egress area (minimum 20 feet) . • Additional rock should be added periodically to maintain proper function of the pad. • See Figure II-5.4 for details. II-5-30 FEBRUARY, 199 STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND HASZN Tire washing should be done before the vehicle enters a paved street. Washing should be done on an area covered with crushed rock and the wash water should be drained to a sediment retention facility such as a sediment trap or basin. • The volume of wash water produced by tire washing should be included when calculating the sediment trap or basin size. Maintenance • The entrance shall be maintained in a condition which will prevent tracking or flow of mud onto public rights-of-way. This may require periodic top dressing with 2-inch stone, as conditions demand, and repair and/or cleanout of any structures used to trap sediment. All materials spilled, dropped, washed, or tracked from vehicles onto roadways or into storm drains must be removed immediately. • All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization is achieved or after the temporary BMps are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil areas resulting from removal shall be permanently stabilized.

SED I KENT RETENTION ,0,6 AJD /x II-5.6.1 B-P E3 10• Filter Fence //��✓^ Code: F F Symbol: -1�---+�`--- Definition A temporary sediment barrier consisting of a filter fabric stretched across and attached to supporting posts and entrenched. The filter fence is constructed of stakes and synthetic filter fabric with a rigid wire fence backing where necessary for support. Purpose 1. To intercept and detain small amounts of sediment under sheet flow conditions from disturbed areas during construction operations in order to prevent sediment from leaving the site. 2. To decrease the velocity of sheet flows. Conditions where Practice Applies • Filter fences must be provided just upstream of the point(s) of discharge of runoff from a site, before the flow becomes concentrated. They may also be required: 1. Below disturbed areas where runoff may occur in the form of sheet and rill erosion; wherever runoff has the potential to impact downstream resources. 2. Perpendicular to minor swales or ditch lines for contributing drainage areas up to one acre in size. Advantages • Downstream riparian areas will not be damaged by sediment deposits originating from the development. • Sediment will not cause damage to fish habitat. Disadvantages/Probleme • Filter fences are not practical where large flows of water are involved, hence the need to restrict their use to drainage areas of one acre of less, and flow rates of less than 0.5 cfs. This flow should not be concentrated; it should be spread out over many linear feet of filter fabric fence. • Problems may arise from incorrect selection of pore size and/or improper installation. Filter fences should not be constructed in streams or used in V-shaped ditches. They are not an adequate method of runoff control for anything deeper than sheet or overland flow. Planning Considerations Laboratory work at the Virginia Highway and Transportation Research Council has shown that silt fences can trap a much higher percentage of suspended sediments than can straw bales. Silt fences are preferable to straw barriers in many cases. However, while the failure rate of silt fences is lower than that of straw barriers, there are many instances locally in which silt fences have been improperly II-5-74 FEBRUARY, 1992 STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN DRAFT installed. The installation methods outlined here can improve performance. Fabric Types: There are four types of material used for filter fabric fences; woven slit-film fabric, woven monofilament fabrics, woven composites (of differing materials) and non-woven heat-treated or needle punched fabrics. Slit-film fabrics are made from woven sheets of nonporous polymers. The sheets are very thin but are cut or slit in wider bands to form the threads which are then woven into the fabric. Since slit- film weaves use strands that are quite thin, the resulting woven fabric has little rigidity, and pore spaces are not uniform. Wire fencing must be used as a backing for this type of filter fabric fence. While this type of fabric is generally cheapest and the most widely used, the additional costs of the wire fence installation must be figured in. Woven monofilament fabrics are made from uniform spun or extruded filaments which are then woven to form the fabric. They are usually thicker and thus more rigid than slit-film fabrics. The pores in monofilament fabrics are regularly spaced and the increased rigidity offers more resistance to pore distortion. The material has a very low flow-through rate. Woven composites are similar in structure but use more than one fiber type. Non-woven fabrics are made by using either continuous filaments or short staple fibers. These fibers are then bonded together by various processes that can include a needling process that intertwines the fibers physically, or a thermal or chemical bonding operation that fuses adjacent fibers together. The resulting fabric has a random fiber orientation and may have a thickness that ranges from thick felt to a relatively thin fabric. King County Conservation District recently completed tests on 18 different types of filter fabrics. Their results have been incorporated into the design criteria. Design Criteria • Drainage area of 1 acre or less or in combination with sediment basin in a larger site. • Maximum slope steepness (normal (perpendicular) to fence line) 1:1. • Maximum sheet or overland flow path length to the fence 100 feet. • No concentrated flows greater than 0.5 cfs. • Selection of a filter fabric is based on soil conditions at the construction site (which affect the apparent opening size (AOS) fabric specification) and characteristics of the support fence (which affect the choice of tensile strength) . The designer shall specify a filter fabric that retains the soil found on the construction site yet will have openings large enough to permit drainage and prevent clogging. The larger the AOS number, the smaller the AOS size of the opening in the fabric. • The material used in a filter fabric fence must have sufficient strength to withstand various stress conditions and it also must have the ability to allow passage of water while retaining soil particles. The ability to pass flow through must be balanced with the material's ability to trap sediments. The following criteria are recommended for selection of the AOS: 1. Because of the properties of soils in the Puget Sound basin, field work must be done to determine the optimum AOS for filter fence installations. Because of glaciation, many soils in this area contain both cobbles and II-5-75 FEBRUARY, 1992 STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN DRAFT fines_ If an SCS standard soil description is used, (e.g, Alderwood gravelly sandy loam) the AOS specified will not be sufficient to trap the finer particles of soil. Including gravels and larger sizes skews the results towards an AOS which is too small to capture suspended settleable solids and reduce TSS. Monofilament and non-woven geotextiles must have a minimum AOS of 70 when used in glacial sails. Composites and slit film fabrics must be extra--strength to perform similarly; in their case the AOS range may be from 40-60. In areas where Mazama ash is plentiful in the soil profile, a larger AOS will be necessary, or, fabric with an AOS of 70 should be used for outwash soils. 2. For all other soil types, the AOS should be determined by first passing soil through a 010 sieve (2.0 mm) . Based on the amount of the remaining soil, by weight, which pasaes through a U.S. standard sieve No. 200, select the AOS to retain 85 percent of the soil. Where direct discharge to a stream, lake, or wetland will occur, then the AOS shall be no larger than Standard Sieve No. 100. Non-woven and regular strength slit film fabrics shall be supported with wire mesh. Filter fabric material shall contain ultraviolet ray inhibitors and stabilizers to provide a minimum of six months of expected usable construction life at a temperature range of 0°F. to 120'F. Standard Notes In addition to the Technical Information Report (see Chapter I-3) required by the local government when preparing an erosion and sediment control plan, add the following notes to the Filter Fabric Fence Detail (Figure II-5.18) : a. The filter fabric shall be purchased in a continuous roll cut to the length of the barrier to avoid use of joints. When joints are necessary, filter cloth shall be spliced together only at a support post, with a minimum 6 inch overlap, and both ends securely fastened to the poet. b. Posts shall be spaced a maximum of 6 feet apart and driven securely into the ground a minimum of 30 inches (where physically possible} . C. A trench shall be excavated approximately 8 inches wide and 12 inches deep along the line of posts and upslope from the barrier. The trench shall be constructed to follow the contour. d. When slit film filter fabric is used, a wire mesh support fence shall be fastened securely to the upslope side of the poste using heavy-duty wire staples at least 1 inch long, tie wires or hog rings. The wire shall extend into the trench a minimum of 4 inches and shall not extend more than 36 inches above the original ground surface. e. Slit film filter fabric shall be wired to the fence, and 20 inches of the fabric shall extend into the trench. The fabric shall not extend more than 36 inches above the original ground surface. Filter fabric shall not be stapled to existing trees. Other types of fabric may be stapled to the fence. f. when extra-strength or monofilament fabric and closer post spacing are used, the wire mesh support fence may be eliminated. In such a case, the filter fabric is stapled or wired directly to the posts with all other provisions of Standard Note "e" applying. Extra care should be used when joining or overlapping these stiffer fabrics. g. Local governments may specify the use of properly compacted native material. In many instances, this may be the preferred alternative because the soil forms a more continuous contact with the trench below, and use of native materials II-5-76 FEBRUARY, 1992 STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN DRAFT cuts down on the number of trips that must be made on and off-site. If gravel is used instead, the trench shall be backfilled with i-inch minimum diameter washed gravel. Care must be taken when using gravel to ensure good contact between the fabric and the trench bottom to prevent undercutting. h. Filter fabric fences shall be removed when they have served their useful purpose, but not before the upslope area has been permanently stabilized. Retained sediment must be removed and properly disposed of, or mulched and seeded. Maintenance • Inspect immediately after each rainfall, and at least daily during prolonged rainfall. Repair as necessary. • Sediment must be removed when it reaches approximately one third the height of the fence, especially if heavy rains are expected. • Any sediment deposits remaining in place after the filter fence is no longer required shall be dressed to conform with the existing grade, prepared and seeded. All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped sediment shall be removed or stabilized on site_ Disturbed soil areas resulting from removal shall be permanently stabilized.

Purpose To prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. Conditions Where Practice Anplies • Where storm drain inlets are to be made operational before permanent stabilization of the disturbed drainage area. Different types of structures are applicable to different conditions: a. Filter Fabric Fence - applicable where the inlet drains a relatively small (less than i acre) flat area (less than 5 percent slope). (see Figure II- S.23) . Do not place fabric under grate as the collected sediment may fall into the drain when the fabric is retrieved. This practice cannot easily be used where the area is paved because of the need for driving stakes to hold the material. b. Block and Gravel Filter - applicable where heavy flows (greater than 0.5 cfe) are expected (Figure II-5.24) . C. Gravel and Wire Mesh Filter - applicable where flows greater than 0.5 cfs are expected and construction traffic may occur over the inlet (Figure II- 5.25) . Advan„taaes • Inlet protection prevents sediment from entering the storm drain system and clogging it. Disadvantages/Problems • Sediment removal may be difficult, especially under high flow conditions. Planning Considerations Storm sewers which are made operational before their drainage area is stabilized can convey large amounts of sediment to natural drainageways. in cases of extreme sediment loading, the storm sewer itself may clog and lose a major portion of its capacity. To avoid these problems, it is necessary to prevent sediment from entering the system at the inlets. There are several types of inlet filters and traps which have different applications dependent upon site conditions and type of inlet. other innovative techniques for accomplishing the same purpose are encouraged, but only after specific plans and details are submitted to and approved by the Plan Approving Authority of the local government (see Design Criteria for the description of a new method currently under development by Emcon Northwest) . Note that these various inlet protection devices are for drainage areas of less than one acre. Runoff from larger disturbed areas should be routed through a Temporary Sediment Trap or Pond (see BMPs E3.35, E3.40) . II-5-87 FEBRUARY, 1992 STORMWATER MANAGEMENT MANUAL FOR THE PUCET SOUND BASIN DRAFT The best way to prevent sediment from entering the stows sever system is to stabilize the site as quickly as possible, preventing erosion and stopping sediment at its source. Design Criteria • Grates and spaces of all inlets should be secured to prevent seepage of sediment-laden water. • All inlet protection measures should include sediment sumps of 1 to 2 feet in depth, with 2:1 side slopes (Figure II-5.23) . • Installation procedure for filter fabric fence: a. Place 2 inch by 2 inch wooden stakes around the perimeter of the inlet a maximum of 3 feet apart and drive them at least 8 inches into the ground. The stakes must be at least 3 feet long. b. Excavate a trench approximately 8 inches wide and 12 inches deep around the outside perimeter of the stakes. C. Staple the filter fabric (for materials and specifications, see BMP E3.10, Filter Fence) to wooden stakes so that 32 inches of the fabric extends out and can be formed into the trench. Use heavy-duty wire staples at least h inch in length. d. Backfill the trench with 3/4 inch or less washed gravel all the way around. • Installation procedure for block and gravel filter: a. Place wire mesh over the drop inlet so that the wire extends a minimum of 1 foot beyond each side of the inlet structure. Use hardware cloth or comparable wire mesh with one-half inch openings. If more than one strip is necessary, overlap the strips. Place filter fabric over the wire mesh. b. Place concrete blocks lengthwise on their sides in a single row around the perimeter of the inlet, so that the open ends face outward, not upward. The ends of adjacent blocks should abut. The height of the barrier can be varied, depending on design needs, by stacking combinations of blocks that are 4 inches, 8 inches, and 12 inches wide. The row of blocks should be at least 12 inches but no greater than 24 inches high (Figure II-5.24) . C. Place wire mesh over the outside vertical face (open end) of the concrete blocks to prevent stone from being washed through the blocks. Use hardware cloth or comparable wire mesh with one half inch openings. d. Pile washed stone against the wire mesh to the top of the blocks. Use 3/4 to 3 inch gravel. • Installation procedure for gravel and wire mesh filter: a. Place wire mesh over the drop inlet so that the wire extends a minimum of 1 foot beyond each side of the inlet structure. Use hardware cloth or comparable wire mesh with 1/2 inch openings. If more than one strip of mesh is necessary, overlap the strips. Place filter fabric over wire mesh. b. Extend the filter fence/wire mesh beyond the inlet opening at least 18 inches on all aides. Place 3/4 to 3-inch gravel over the filter fabric/wire mesh. The depth of the gravel should be at least 12 inches II-5-8 FEBRUARY, 1992 STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN DRAFT over the entire inlet opening (see Figure II-5.25) . Experimental Inlet Protection BMP: EMCON Northwest, Inc. has recently developed a catchbasin. filter (patent pending) that prevents sediments and other contaminants from entering storm drainage systems. The catchbasin filter is inserted in the catchbasin just below the grating. The catchbasin filter is equipped with a sediment trap and up to three layers of a fiberglass filter material (see Figure II-5.26) . This type of system may not be applicable in all catchbasins but would work well at construction sites, industrial facilities, service stations, marinas/boatyards, etc. During research and development of the catchbasin filter, EMCON Northwest, Inc. has found that particulates as small as 15 microns are retained by the filter. Additionally, high levels of particulate heavy metals, oil and grease and TSS have been removed at both industrial facilities and construction sites. The catchbasin filter is equipped with an overflow mechanism which allows it to pass peak flows up to 240 gallons per minute. Effective filtration can be accomplished at flows as high as 40 gallons per minute. For further information, contact John MacPherson at EMCON Northwest Inc. , (206) 485-5000. Please note that this information is presented fcr informational purposes only. While this technology appears to be an effective method of controlling some types of pollutants, Ecology is not in a position to confirm or deny its efficacy at this time. Maintenance • For systems using filter fabric: inspections should be made on a regular basis, especially after large storm events. If the fabric becomes clogged, it should be replaced. Sediment should be removed when it reaches approximately one-half the height of the fence. If a sump is used, sediment should be removed when it fills approximately one half the depth of the hole. • For systems using stone filters: If the stone filter becomes clogged with sediment, the stones must be pulled away from the inlet and cleaned or replaced. Since cleaning of gravel at a construction site may be difficult, an alternative approach would be to use the clogged stone as fill and put fresh stone around the inlet. • All temporary and permanent erosion and sediment control practices shall be maintained and repaired as needed to assure continued performance of their intended function. All maintenance and repair shall be conducted in accordance with an approved manual. • All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization is achieved or after the temporary BMPS are no longer needed. Trapped sediment shall be removed or stabilized on site. Disturbed soil areas resulting from removal shall be permanently stabilized.
