Answer: Normally the homeowners adjacent to the planter strip maintains the landscaping Typically the planter strips are in the front of the house However, in this particular situation it will be the rear yards adjacent to the planter strips and they will be physically separated by a solid wood fence The City will maintain the planter strips and street trees along Canal Street and Rhoton Road Question #2. For the interior streets will water spigots on individual houses be adequate to meet irrigation requirements for the planter strips? Answer: Yes, as long as no planter strip area is farther than 75' from a water spigot. Question #3 Does the landscaped area along the western property line need irrigation? Answer: Because of the need to leave the area undisturbed as much as possible the City will not require irrigation along the western property line, provided the selected plants are suitable for the types of soil and that you will ensure the plants will be watered and maintained for the first two years If you have any questions, please contact me at (360) 458-8408 Sincerley, I " GLftu.., Lc lue..

I would like to give you the bnef history for speclfymg a prefabncated storm dram age treatment devlce for Canal Estates. In preparing the prelinunary grades & dralllage drawmgs for the prelimmary plat applIcatIOn It became apparent that conventional stonn water treatment, i.e wet pond, swales, etc would not fit wellm tl)IS subdIVl5l0n. I contacted, then DlTector of PublIc Works, Ken Garmann, and discussed the use of a prefabncated stonn water treatment devIce. Mr Gannann saId he would allow the use of these deVICes. 1 proceeded WIth preparing the prelimmary grades & dram age drawmgs aIld the prelImmary dramage report WIth one of these devices incorporated mto the prelImmary designs These documents where subIUltted to the CIty WIth the prehmmary plat apphcatIon and approved by the Yelm Plannmg CommIsSIon and CIty CounCIl. The constmctlOn documents were prepared based on the approved prelImmary plat applicatIon documents. The Department of Ecology (DOE) Stormwater Management Manual states that all projects shall provide treatment of storm water The treatment system shall be sIzed to capture and treat the quantIty of runoff from a 6-month, 24-hour stonn event. Sechol1 1-2,8 of the manual states that the purpose of runoff treatment is to reduce pollutant loads and concentrations using physical, biological and chemical removal mechanisms. The treatment method of the BA YSA VER@ prefabrIcated treatment device specified on the construction documents is physIcal. It provIdes removal of suspended sedIments, free 011 and floatmg debns The 1992 DOE manual does not specify a perfonnance standard for the removal of pollutants. However, It reqwres the use of Best Management PractIces (BMPs) to reduce the pollutant levels in the: storm water runoff. The Umverslty of Maryland conducted a study on the performance of the BA YSA VER@ The results show that on an average 78%-81 % removal ofTSS (Total Suspended SolIds) IS achieved. Studies conducted by the USEP A and others have shown that swales remove 68%- 83% ofTSS and wet ponds remove 50%-90% ofTSS t-'--.

The manual prOVIdes for local jurisdictions to approve the use of these devIces. The Cltles of Olympia, Tumwater and Lacey, along wIth Thurston County have allowed the mstallatlon of prefabncated storm water treatment devices m both reSIdential and commerclal/industnal developments, The Waslungton State Department of TransportatlOn (WSDOT) has several of these units installed at various sItes throughout Western Washington.

After review of the Planning Commission's recommendation, pubic hearing comments and the staff report dated July 20, 1999, the City Council found the project, as conditioned in the staff report, to be consistent with all applicable City policy's and development standards and approved the preliminary plat Preliminary Plat approval is valid for 5 years from July 28, 1999 Within the 5-year period all conditions of approval shall be satisfied and an application for final plat shall be submitted to the City for the project to remain vested The project is approved subject to the following findings and conditions of approval Findings. 1 Proponent. Prairie Electric Co , Erling Birkland 2 Location. Southwest corner of Canal Road and Rhoton Road Tax Parcel 22718310300 3 Public Notice Notice of the Public Hearing was published in the Nisqually Valley News on Juiy 9, 1999, and posted In public areas on July 1, 1999 The notice was maIled to adjacent property owners and the applicant on July 1, 1999 4 Existinq Land Use Vacant. 5 Adiacent Land Uses Low Density Single family residential 6 Comprehensive Plan The site is designated Low Density - Residential Mr Erling Birkland August 2, 1999 Page 2 7 Zoning Chapter 17 12, Low-Density Residential District (R-4) 8 Soils and Geology Spanaway gravelly sandy loam 9 Ground Water The project site is located in a Category I Aquifer Recharge area Ground water levels on the site are fairly close to the surface (30' or less in some areas) especially along the western property line and the southwest corner of the site In 1996/1997 the area to the west and south of the site experienced high groundwater levels which resulted in localized flooding Topographic information indicates that the regional low area is along and west of the site's western property line 10 Transportation and Site Access. The site fronts on both Canal Road and Rhoton Road The Yelm Development Guidelines, Section 4B 130, requires a minimum spacing of 200' between intersections that include a designated Neighborhood Collector Street. The Yelm Development Guidelines, Chapter 4, classifies Canal Road and Rhoton Roads as Neighborhood Collectors The newly constructed internal road would be classified as a Local Access Residential Street. Consistent with City of Yelm Ordinance 580, Concurrency Ordinance, a single family dwelling unit generates 1 01 new pm peak hour trips As proposed the development would generate 26 new pm peak hour trips The Concurrency Ordinance requires that impacts to the transportation system from new traffic be mitigated through the Transportation Facility Charge of $750 00 per new pm peak hour The preferred alternative for the Y -3 transportation corridor runs from east to west along the southern property line and 120' deep The route is currently being analyzed through an environmental assessment with the final adoption of the transportation corridor to occur in the late summer or early fall of 1999 Because the corridor is not adopted at this time, the City can not require the developer to alter the site lay-out to accommodate the future right-of-way Staff has reviewed the lay-out with consideration of the future Y-3 corridor and believes that through traffic control (one-way street) that the infrastructure constructed for the project will not have to be physically altered The future acquisition of right-of-way for the Y-3 corridor will include lots 1 - 9 Acquisition of right-of-way can not begin until the corridor is adopted by the City Council and funding is available 11 Parking Chapter 17 72, Off-Street Parking and Loading, requires two (2) parking stalls for each residence 12 Wastewater The project site is in the Sewer Service Area but is not currently served by the Sewer Treatment Plant. The existing service line designated to serve the site is Mr Erling Birkland August 2, 1999 Page 3 located at the intersection of View Drive and Rhoton Road As determined in the City's 1998 Sewer Comprehensive Plan the project site is located at the end of the 4" service line planned to serve the site 13 Water Supply The project site is in the Water Service Area, but is not served with City water The existing service lines designated to serve the site are an 8" line located at the intersection of View Drive and Rhoton Road and a 10' line located west of the property on Canal Road The City's 1995 Water Comprehensive Plan requires these lines to be connected in the future to ensure adequate fire flow for the area 14 Drainaoe/Storm water The completed project will increase impervious surfaces on the site and adjacent streets Impervious surfaces create stormwater runoff When uncontrolled and untreated stormwater runoff can create health and safety hazards YMC requires all development to comply with the City Stormwater Manual for the control and treatment of stormwater runoff Stormwater facilities require continued maintenance to ensure they remain in proper working condition The preliminary stormwater report and conceptual layout appear to meet minimum City standards 15 Open Space. Chapter 16 14, Parks and Open Space requires single family residential developments to provide 5% of the development site in improved open space or pay a fee-in-lieu of providing on-site open space The applicant is proposing to pay the fee-in-Iieu of rather than providing on-site open space The fee-in-Iieu of is calculated by multiplying 77~ per square foot of required open space 5% of the gross site represents 33 of an acre (14,288 00 sq ft.) The fee-in-Iieu of for the project site is $11,0001 76 The fee-in-lieu of is payable prior to final plat approval, unless the City approves a property lien against each lot and then the fee-in- lieu of would be payable at time of building permit issuance The applicant has not requested a property lien for the fee-in-lieu of 16 Utilities The site is served by Puget Sound Energy (electric and gas) and Yelm Telephone 17 Fire Protection Fire protection is provided by the Thurston County Fire District #2 The applicant has submitted Fire Flow Calculations for existing hydrants located at Crystal Springs and Canal Road which meet current city standards Mr Erling Birkland August 2, 1999 Page 4 18 Police Protection Police protection is provided by the City of Yelm 19 Public Schools The project site is within the Yelm School District.

The site fronts on both Canal Road and Rhoton Road The Yelm Development GUidelines, Section 4B 130, requires a minimum spacing of 200' between intersections that include a designated Neighborhood Collector Street. The Yelm Development Guidelines, Chapter 4, classifies Canal Road and Rhoton Roads as Neighborhood Collectors The newly constructed internal road would be classified as a Local Access Residential Street.

When urban and suburban devel0pment covers the land with buildings, houses, streets and parking lots, much of the natiJe topsoil, duff, trees, shrubs and grass are replaced by asphalt and concrete Rainfall th~t would have soaked directly into the ground instead stays on the surface as stormwate~ runoff making its way into storm drains (including man- made pipes, ditches, or swale n~tworks), stormwater ponds, surface and groundwater, and eventually to Puget Sound I What is a Storm Drain System and how does it work? The storm drain system for mostl developments includes components that carry, store, cleanse, and release the stormwater These components work together to reduce the impacts of development on the e~vironment. These impacts can include flooding which results in property damage and blocked emergency routes, erosion which can cause I damage to salmon spawning habitat, and pollution which harms fish and/or drinking water supplies LJ II u II II LJ I) LJ I) LJ II The storm drain system provides? safe method to carry stormwater to the treatment and storage area Swales and ponds filter pollutants from the stormwater by physically settling out particles, chemically binding pbllutants to pond sediments, and biologically converting pollutants to less-harmful compouhds The ponds also store the treated water, releasing it gradually to a nearby stream or td groundwater The various components of storm drain systems are described in the glos~ary What does Stormwater Runoff hate to do with Water Quality? Stormwater runoff needs to be tr11eated because it carries litter, oil, gasoline, fertilizers, pesticides, pet wastes, sediments, and anything else that can float, dissolve or be swept along by moving water Left untrsated, polluted stormwater can reach nearby waterways where it can harm and even kill a~uatic life It can also pollute groundwater to the extent that it must be treated before it can be used for drinking Nationally, stormwater is recognized as a major threat to water quality Remember to keep everything out of stormwater systems except the rainwater they are designed to collect. Your Neighborhood Stormwater F~cility I Stormwater facilities can be attractive as well as functional They can provide both active and passive-use recreation areas land open space for wildlife Perhaps you've noticed a wet pond or dry pond in your neighborhood These different types of ponds are designed I for different purposes For example, wet ponds primarily provide treatment of stormwater They also provide good cover and I habitat for birds and small mammals, making them fine "wildlife preserves" Dry ponds or infiltration ponds are designed to provide storage for stormwater and gradually release it downstream or allow it to filter into the ground These I I 'l U n LJ " u n LJ n u 'I LJ '1 U LJ " LJ II HOWARD GODAT, PANTIER & ASSOCIATES DRAINAGE REPORT - Canal Estates Page 24 LJ '1 LJ n LJ types of ponds can be maintained as grassy play areas, and may even house formal play equipment.

Manufacturers may truthfully state that a product is "biodegradable", most products are biodegradable, but what is important is the rate at which they are broken down and the products they are broken down into The term "biodegradable" on its own is misleading at best, unless the product is rapidly degraded into harmless substances LJ " LJ 11 U It is important to note here that the term "biodegradable" currently has no legal definition in this state This means that any product can use this term according to the manufacturer's own definition This definition may not be at all similar to the consumer's perception The following ideas will help you reduce the risks of stormwater and ground water contamination from many household products II J " u II LJ '1 U II HOWARD GODAT, PANTIER & ASSOCIATES DRAINAGE REPORT - Canal Estates Page 39 u II LJ n u HOUSEHOLD PRODUCT MANAGEMENT n I Read the label of products before you buy them.

Do not dump them onto the ground because they will end up m stormwater runoff or m groundwater Do not use oil to reduce dust levels on unpaved areas. Instead, recycle used oil and antifreeze. Keep them m separate contamers. Call the Recycling Hotlme at 1-800- RECYCLE or call the Thurston County Health Department for the locatIon of the nearest recyclIng center, or call your local automotIve servIce centers to see If they take oil for recycling.

Use only the recommended amount of fertilizer, and add any soil amendments, such as lime, that are recommended m your test results. 2. Use fertilIZers that are appropnate for your area, and for the type of plants you are growmg. Work the fertihzer mto the soil dIrectly around the plant's dnp lme. By mcorporatmg the fertilIZer in the soil, there will be less likelihood of contaminated runoff. Contact the Thurston ConservatIOn DIStrIct to find out thIS mformation. 3 Water before fertihzmg. Water enough to dampen the ground thoroughly, but not enough to cause surface runoff. Dampening the soil prevents fertilizer from being washed from the surface of dry soil in the first ram or watenng after apphcatIOn 4 Many soils can benefit from the use of orgamc fertihzers such as compost or peat. Not only do these substances add nutrIents to soil, they also mcrease the pOroSIty of the soil and increase its ability to hold water 5 Slow release fertilizers (which are generally resin-coated) can be used m addItIon to orgamc fertihzers. They are not mobile in the soil, and are only applied once. Integrated pest management Rather than bringing out the sprayer whenever a pest infestation occurs In the garden, consider using Integrated Pest Management (also known as IPM) IPM emphasizes the evaluation of all factors including environmental effects before chemicals are applied Pesticides should only be used as a last resort. Some of the tactics that can be used to decrease or eliminate the use of pesticides include n I LJ II LJ n LJ " J 'l I U II n LJ n U Use of Natural Predators, Pathogens: Because chemIcal sprays generally kill many beneficial insects instead of Just the target pest, It may be necessary to mtroduce natural predators back mto the garden. Ladybugs, lacewmgs, predatory wasps, and nematodes are all commercIally available Garter snakes and toads are also predators and should not be ehmmated from the garden. " n There are some bactena, viruses, and insect parasItes that are specific to pests and will not harm other insects or animals. A commonly used bacterium in the Puget Sound area is Bacillus thuringIensIs (Bt), which IS mtended to control infestations of tent caterpillars. Products contammg Bt are available at your nursery Habitat Changes: Many tImes a change of habItat can control pest mfestatIOns. Removal of old tIres can cut down on the mosqmto population by removing a convement water-filled locatIon for them to breed in. Crop rotatIon, even in a small garden, can reduce the number of pest infestatIons. Removing last year's leaves from under rose bushes can cut down on the inCIdence of mildew and blackspot, as these fungi overwmter m dead leaves. Timing: Crops that can overwmter (such as leeks or carrots) should be planted m the fall. This gives them tIme to become estabhshed before pests amve m the spnng. Mechanical. Many eggs, larvae, cocoons, and adult insects can be removed by hand. Be sure that the insect IS properly IdentIfied prior to removmg It so those beneficial msects are not destroyed m error Drowmng msects in plam water or spraymg them with soapy water are alternatives to squashing them.

Many plant cultivars have been developed whIch are resIstant to such diseases as vertIcihum wilt and peach leaf curl. Grass seed mixes are also available for lawns that need much less watering, mowing, and chemical use Growing Conditions: Plants, such as hostas, that reqUIre some shade are more susceptible to pests when they are growing in the sun. Plants that are not properly fertihzed or watered are less vigorous in growth and tend to attract pests. Plants that prefer an aCId soil, such as azaleas, will perform better and be less susceptible to pests when they are grown m soil wIth the proper pH. Chemicals. ChemIcals are a small part of the IPM plan and should be applied only as needed after revIewmg all other alternatives. u I) LJ " LJ n LJ Pesticide management When use of a chemical is the best or only option, follow these simple guidelines 11 U Know what pest you are spraying for Use the pestICIde accordmg to the manufacturer's instructIOns and buy only the quantIty needed. Many pestICIdes have a hmIted shelf hfe and may be useless or degrade mto even more toxic compounds Ifkept on the shelf. 2 Do not apply more than the specIfied amount. Overuse can be dangerous to your health as well as the health of wildhfe and the enVIronment. If more than one chemIcal can be used to control the pest, choose the least tOXIC The word "cautIOn" on the label means that the chemical is less toxic than one that IS labeled "warnmg" 3 Do not spray on wmdy days, m the mornmg of what will be a very hot day, or when ram IS likely to occur Herbicides can drift and mJure valuable ornamental plants m eIther yours or your neIghbor's back yard. Do not water heavily after apphcatIOn. Plants should be hghtly watered BEFORE application to prevent burning of the fohage, and to help evenly spread the chemIcal. 4 Never apply pesticides near streams, ponds, or wetlands (exceptIon. approved apphcatIOns for aquatIc weeds) Do not apply them to bare eroded ground (exception. use of low tOXICIty herbIcIdes such as Round-up to allow growth of desired planting in small areas) Many pestIcIdes bmd to soil partIcles and can be easily carried into a stream or storm drain. S PestIcIdes should be stored well away from hvmg areas. Ideally, the storage area should have a cement floor and be insulated from temperature extremes. Always keep pesticides m therr ongmal contamers wIth labels m tact. Labels often corrode and become illegible m this climate and may have to be taped onto the container 6 Federal law now requires that all pesticIdes be labeled wIth the appropnate disposal method. Leftovers should never be dumped anywhere, mcludmg a landfill. Take unwanted pestIcIdes to the County's hazardous waste collection days or Hazo House at the landfill. 7 Empty containers should be triple-rinsed and the rinse water used as spray Once containers are triple- rinsed, they are not consIdered hazardous waste and may be dIsposed of m most landfills. However, call your local landfill before putting the container in the garbage. 8 If a pestIcIde IS spilled onto pavement, it can be absorbed usmg kitty htter or sawdust. The contammated absorbent should be bagged and labeled and taken to Hazo House. 9 If the pesticide is spilled onto dIrt, dIg up the dIrt, place it in a plastIc bag and take it to Hazo House 10 Many pest control companies and licensed applicators have access to pesticides that are more toxic than those available to the consumer Check wIth the company before they spray mdoors or outdoors to find out what spray they will be usmg and what precautions, if any, are necessary after the operator leaves.

Wood deckmg allows ramwater to dnp onto the ground below, keeping it from becoming surface runoff. 2 Decks and sIdewalks can also be built out of brick interlockmg pavers or modular concrete If these surfaces are placed on a bed of well-drained soil gravel or sand, ramwater can mfiltrate mto the around through them. 3 To reduce dIsposal problems, buy only the amount you need. Used turpentme or brush cleaner can be filtered and reused. Pamt cans should be allowed to dry and then be dIsposed of durmg a hazardous waste collectIOn day or at Hazo House 4 Leftover paint can be given away, for example to a theater group Contact the Thurston County Health Department at 754-4111 for other options. 5 Roof downspouts can be adjusted to mfiltrate runoff where the soil IS well dramed. The runoff from them can enter a gravel bed where It can mfiltrate mto the ground. For desIgn cntena, see your JunsdIctlon's drainage manual. 6 When gardening on slopes, reduce the potential for surface runoff by using terraces across the face of the hill.

"B" horizons generally have an accumulation of clays or salts. "C" horizons are generally either undifferentiated parent material or are below the zone of major biological activity A small letter following the capital letter provides additional information. "Bw" describes a "cambic" or barely developed B horizon; A "cw", "cs" or "ci" after a B or C describes a horizon with weak cementation, strong cementation, and induration respectively An "r" after a B or C indicates that the horizon is dominated by saprolyte; which is rotten rock -- i.e. rock that is so decomposed that it is almost soil. An "R" after a C indicates that the C horizon is predominantly hard, undecomposed bedrock. A "2" in front of a B or Chorizon indicates that the subsoils have a different parent material than the overlying soils. Dpth = depth: gives the distance from the surface for the top and bottom of each horizon. Col = color' gives a Munsell Book color chip code. The Munsell color codes (example:lOYR 3/4) give information on the hue (lOYR), value (3), and chroma (4) of the soil. Soil color can be used to infer parent material, percent organic content, or soil drainage characteristics. For example, soils with both low chroma and value (example: 10YR 2/2) are, very dark-colored and tend to have high organic matter contents; soils with a Munsell chroma code of2 or less (example: lOYR 7/2) may be poorly drained. The following value/chrome color codes correspond to the following soil color names for the two most commonly used HUE pages lOYR and2;5Y 10YRHUE COLOR NAME , white' light gray gray dark gray vetoi dark gray hlac!\ ' very pale brown light brownish gray grayish brown dark grayish brown very dark grayish brown very dark brown yellow ,pale brown ' brown dark brown light yellowish Drown brownish yellow yellowish brown dark yellowish brown '.

Coarse fragments are defined as any mineral fragment in the soil greater than 2mm diaineter If needed, coarse fragments are also described in terms of various size classes -" gravel, cobble, stone, etc. Abbreviations associated with CF percentages will be: Co = cobbly (coarse fragments> 3 " diameter), 'Cn= cOncretions (small, round pebble- like fragments formed by soil minerals dissolving and then re-precipitating). If no abbreviation is included, assume that the percent CF is describing gravels (coarse fragments >2mm and <3" in diameter). ~~~~~~~ -.,- .r ~, ," Page 1 .-" '~~;-'~o;-----r:.', '1 LJ II LJ II U " U " LJ " U II LJ II U h LJ n u n U h U " LJ , n LJ i'. LJ h i LJ II LJ II U 'l U - If cOarse fragment content is expressed as 15-35 percent, the tine fraction (soil particles less than 2 mm diameter) textural call is modi tied and detined as gravelly (Le. gravelly loam or gravelly silty clay); 35-65 percent is very gravelly; greater than 65 percent is defined as extremely gravelly Struc = structure: describes the shape and size ofthe natural soil clods. Soil with strong structure is generally considered to be stable and well developed. Soils that are periodically disturbed generally have poor structure. Fine textured soils with weak structure often have poor percolation capabilities. . OM = percent organic matter In mineral soils, organic matter decreases with distance from the soil surface. Low percentages (3% or less) at the surface can indicate erosion problems. Increased percenjages below the surface can indicate a buried surface (fill on the surface). Organic matter improves structure and fertility Surface OM% in mineral soils ranges from 4 to 20.%. When OM% is greater than 20.%, the soil may be classified as an organic rather than mineral soil. This is generally indicative of saturated and/or cold conditions in the soil. Root = rooting depth: can be used to locate layers in the soil that may restrict growth or water movement. Mott = mottles: are an indication that the soil goes through alternating periods of extended saturation and drying. Perc = percolation rate. The percolation rate is an estimate of inches per hour water percolation through the soil. The range in percolation rates as devised by the SCS are as follows: Class Very slow Slow Moderately slow Moderate ,_ Moderatelyrapid Rapid Very rapid Estimated incheslhour less than 0..0.6 0..0.6-0..2 0..2-0..6 0.,6-2.0. 2.0.-6.0.' 6.0.-20. , 'more than 20. The tield estimate is made based on soil texture, percent coarse fragments, and other soil features, such~' indication of cementing and the presence of mottles; \ -'" Type = soil type: as detined inArticleN, Rules and Regulations of the Thurston County Board'ofHealthOoverning Disposal of Sewage (same as State definition); These groupings have been recently reviewed' and revised at the State level, but in general indicate soil texture and relative percent of coarse fragments with the Type 1 soils being the most cOarse-textured with the highest coarse fragment percentage and the Type 6 soils being the'tinest textued. Similar to soil percolation rate estimates, the field typing estimate is based on interpretation of effects of soil texture, percent coarse fragments; and other sOil features, such as indication of cementing and the presence of mottles. In general, soii type 1 is too coarse textured to allow for a standard design. Some pre-treatmetn design is used, then the native soils are used > for disposal ofthe tr~atrede:fl:luent., Soil types 3 aI?-d 4'are generally preferred, although some type 4's may be limited to 'some degree by slow percolation; type 5 sOils percolate very slo\'{ly and are generally less desireable due to how easily they are hydraulically .overloaded; but mound or pressure distribution systems can be used in some cases to compensate for th,ese Jimitations;,type 6 soils are unsuited due to minimal percolation.

The results are available across the counter at DNR Map and Photo Sales. The current stream type definitions are as follows (paraphrased from the WAC code descriptions): Stream Type 1 Typical characteristics All shorelines of the state, as defined under RCW 90.58, within their ordinary high water mark, excepting their associated'wetlands. Generally, these include all rivers, lakes greater than 20 acres, and perennial streams downstream of the point of greater than 20 cfs flow' These are generally considerel,i to be fish-bearing waters. 2 These are not Type I waters, but do have high fish, wildlife, or human use values. They include segments of natural waters and their associated wetlands which: (a) are diverted for domestic use by more than-lOO residential or carrtpingunits..., (9) are within any campground with-greater than 30 camping units~.., . : (c) are used by'substantial numbers ofanadromous or resident game fish for spawning, rearing or migration, stich as those having a defined channel width of 20 feet or greater and a gradient of less than 4%, or lakes,.ponds or impoundmellts with greater than 1 acre of surface area at seasonal low water (d) are used by salmonid for off"ChaIinel habitat~ usually critical for juvemlesurvival;'such as those areas connected to ,a slmonid bearing stream and acCessible at some ti!De of the year and having an" access " drainage area witilless than 5~ gradient.

Stormceptor removes free oil and suspended solIds from stormwater preventIng spills and non-pomt source pollutIon from entenng downstream lakes and nvers. A summary of the key benefits related to the unplementatIon of a Stormceptor IS as follows LJ " LJ n . Capable of remov1Og 50% to 80% of the total sedIment load when properly applIed as a source control for small areas · Removes free oil from stormwater dunng normal flow condItIons · Will not scour or resuspend prevIOusly trapped pollutants. · Can be unplemented as part of a treatment tram (ex. prevents groundwater contaminatIon in recharge measures, extends the mamtenance penod for other stormwater qualIty measures) . Excellent spills control deVIce for commercial and 10dustnal developments · Simple to deSIgn and specify · InexpensIve compared to other stormwater qUalIty measures · Easy to install in new or retrofit SItuatIons · Easy to mamtaIn (vacuum truck) · Can be used as a bend structure · Pre-engmeered for traffic 10ad1Og . Stormceptor clearly marked on the cover for IdentIfication e u " u " LJ II LJ II u II u II Although the Stormceptor is extremely versatile, users of this document should keep in mind several key constraints: LJ " . The Stormceptor cannot be used as a storm dram Inlet . The difference between the Inlet pIpe Invert elevatIon and the outlet pIpe elevatIon must be 1" (25 mm) for a SIngle inlet - single outlet applIcatIon . The difference between the Inlet pIpe mverts and outlet pIpe invert must be 3" (75mm) for a multIple Inlet - SIngle outlet applIcatIon · The largest standard inlet/outlet SIze that can be accommodated WIthOut custormzatIon IS 36" (914 mm) LD pIpe . 3 feet of cover is recommended above the crown of the pIpe (inSIde top of pIpe) to grade for the Stormceptor However, special allowances can be made.

The by-pass IS an mtegral part of the Stormceptor smce other types of oil/gnt mterceptors have been noted to scour dunng hIgh flow condIllons (Schueler and Shepp, 1993) u " u " u II LJ " LJ ".... ~ LJ II u Stormcepto~ II LJ II LJ II LJ II u DESIGN AND OPERATION The utility-patented Stonnceptor consists of three sections: a "separation/storage" chamber at the bottom, a "bvpass" chamber above, and a central maintenance shaft that rises through both to street level. II u II Under nonnal, or "design flow" operating conditions, stonnwater flows into the upper bypass chamber, is diverted by a v-shaped weir down a pipe, and into the "separationlholding" chamber. This dowll\vard flow is directed, by right- angled outlets, around the circliliIr walls of the chamber, and flows horizontally to the outlet pipe. Above and below this throughflow, oil and sediment accumulate in relative quiescence. Up to 80% of the inflowing fines and coarse sediment load settles down to the floor of the chamber, while the petroleum products and volatile vapours rise and become trapped. u n u II LJ II u n u II u 'l U " u n LJ II , u n u II LJ '1 LJ II LJ DOES NOT SCOUR During high flow periods -which represent approxi- mately 1;% of all events -stonn watersurges flood over the diverting weir and continue through the bvpass chamber into the down- stream sewer. This rapid activity creates pressure equalization across the bvpass chamber, thus decreasing flow through the separation chamber which will prevent scouring. A proportion of incoming sediment continues to hit the weir and collect in the lower chamber where it remains, with any residual petroleum products, for scheduled removal. ,--, , , u ,- I!

Inc. 195 The West Mall, Suite 405 Eroblcoke, Ontario CANADA M9C SKI RE: Design of Oil/water Separators for Storm water Treatment Dear Mr. Bryant: We are contaeting teChnical personnel that may have an interest in reviewing a draft revision of the oil/water separator design criteria of Volume III-7 of the Storm water Management Manual prepared by the WashingtOn State Department of Ecology . You have been selected as a potentially interested pany based on recent discussions with you or correspondence or literature on oil/water separators. The enclosed first draft is a revision of the current February. 1992 version. We've also attaChed a copy of the current version for comparison. The following are the SIgnificant differences: 1. Changing the design criteria for smaller separatOrs tributary to less than five acres drainage. The current API criteria results in very long separators for small applications. This would affect gas stations. high-use commercial parking lots. and small industrial sites. 2. Using a design flow based on the peak flow during the calculated minimum hydraulic residence time. 3. Inclusion of a new technology, Stormceptor. because the developer has provided reasonable field data on performance. 4. I've added emphasis on: . Performance goals based on discharging below significant amountsl discharge targets. . When to apply an oiUwater separator. · Operation and Maintenance. -~- - \.1 OlL89~991v 'ON Xijj HOld30WH01S Wd EE:EO NOW 96-11-^ON II u 'I u . Obtaining an oil rise rate empirically, using the STS teSt, if feasible, or by using StOkes Law. . Controlling solids before the oil separatOr bays. . Control of CP separator fouling/plugging. . Bypassing high stormwarer flows. II u " LJ II Please consider technical content, layourlformat, illusmuions, and any other informanon you feel would make this document more user-fnendly and effecnve. Please note that the new and/or major rmpact criteria are underlined and in italics. You may proVlde comments by letter or by including notations on a copy of the draft.
