Per the Uniform Building Code and /or Uniform Mechanical Code, every permit issued by the building official under the provision of this code shall expire by limitation and become null and void if the building or work authorized by such permit is not commenced within 180 days from the date of such permit, or if the building or work authorized by such permit is suspended or abandoned at any time for a period of 180 days, after the work is commenced. Based on the above, the Permit Center will close your file and the work completed to date will be considered non- complying and not in conformance with the Uniform Building Code and /or Mechanical Code. Please contact the Permit Center at (206) 431 -3670 if you have further questions. Thank you for your cooperation in this matter.

Some of the conditions apply to erosion prevention and sediment control. Keystar is not meeting these conditions. A summary of the City's erosion prevention and sediment control requirements and a copy of the permit conditions is enclosed. Keystar installed silt fence as perimeter protection, but has not maintained the fencing. In addition, in some locations the silt fence is being used more as a retaining wall, which is contrary to its intended use. None of the unworked areas have cover measures. All year round the City requires seeding on all disturbed areas which will be unworked for 30 days or more. From May 1 through September 30, the City requires temporary cover measures on ALL areas left undisturbed for more than seven days. Beginning October 1, all disturbed areas left unworked for more than two days shall be covered and all seeded areas must be mulched by October 8 All of the lots, except part of lot A and part of lot H, have been unworked for several weeks. In addition, there are cuts into the steep slopes which have no erosion prevention measures on them. City of Tukwila Department of Public Works Steven M.

Keystar has installed erosion silt fence in an in an inappropriate application and has not provided temporary cover for the nearly two acres of disturbed soils. The following summarizes the City's standards for cover measures: May 1 through September 30, temporary cover measures shall be installed on ALL areas left undisturbed for more than seven days. October 1 through April 30, temporary cover measures shall be installed on ALL disturbed areas left unworked for more than TWO DAYS. These requirements may be relaxed at the City's discretion, depending on site topography and other conditions. At all times, any disturbed areas left unworked for more than 30 days shall be seeded. Wet season requirements — At a minimum, the ESC plan and plan notes shall provide the following for work which will occur from October 1 through April 30: • Install temporary cover measures on all areas which will remain unworked for more than TWO DAYS and on stockpiles and steep cut and fill slopes. • Retain onsite a quantity of cover measures materials sufficient to cover all disturbed areas. • By October 8, temporarily seed and mulch all areas that will be unworked during the wet season. • Mulch all seeded areas. • Stabilize all construction traffic areas, unless already graveled. MME SUMMARY OF CITY ESC REQUIREMENTS The erosion prevention and sediment control (ESC) plan shall be designed in accordance with the current edition of the King County Surface Water Design Manual. The plan shall provide information for temporary erosion prevention and sediment control during all phases of construction and also shall provide permanent stabilization for disturbed areas. During construction, the City may require additional measures as needed to prevent erosion and retain sediment. 1. Principles — The plan shall emphasize erosion prevention rather than sediment control and shall minimize the extent and duration of soil exposure. In addition, the plan shall minimize runoff -off velocities and retain sediment on -site. 2. Plan — At a minimum the ESC plan shall show clearing limits, sensitive area buffers, and shall provide temporary stabilization, sediment retention , and perimeter protection. In addition, some projects will require stabilized traffic areas and surface water controls, which shall be shown on the ESC plan. The plan shall also provide a description of final stabilization methods. 3. Seeding — The plan shall provide the seed mix for the temporary and permanent seeding. 4. Cover measures — May 1 through September 30, temporary cover measures shall be installed on ALL areas left undisturbed for more than seven days. October 1 through April 30, temporary cover measures shall be installed on ALL disturbed areas left unworked for more than TWO DAYS. These requirements may be relaxed at the City's discretion, depending on site topography and other conditions. • At all times, any disturbed areas left unworked for more than 30 days shall be seeded. 5. Wet season requirements — At a minimum, the ESC plan and plan notes shall provide the following for work which will occur from October 1 through April 30: • Install temporary cover measures on all areas which will remain unworked for more than TWO DAYS and on stockpiles and steep cut and fill slopes. • Retain onsite a quantity of cover measures materials sufficient to cover all disturbed areas. 3 ,R? .'X;14 " ISVFMKTIV r7 .1 • By October 8, temporarily seed and mulch all areas that will be unworked during the wet season. • Mulch all seeded areas. • Stabilize all construction traffic areas, unless already graveled. ESC MAINTENANCE 1. Failure to maintain ESC measures in accordance with the approved maintenance schedule may result in the work being performed at the direction of the Director and assessed as a lien against the property where such facilities are located. 2. During the life of the project, the Applicant /Owner shall maintain in good condition and promptly repair, restore, or replace all grade surfaces, walls, drains, dams, structures, vegetation, erosion and sediment control measures, and other protective devices in accordance with approved plans. 3. The Applicant /Owner shall monitor the downstream drainage features, and shall, with City approval, remove all sediment deposition resulting from project - related work. 4. The City shall assume maintenance and operation responsibilities for all ESC measures located within public easements and rights -of -way, following final acceptance of such facilities by the City. ESC DURING CONSTRUCTION 1) As the first order of business, the Permittee shall install erosion prevention and sediment control measures per the ESC. Install the downstream temporary ESC measures before any site disturbance occurs. Before the temporary measures are removed, install and establish the upstream permanent ESC measures. 2) The Permittee shall at all times protect sensitive areas, their buffers, and adjacent private properties and public rights -of -way or easements from damage during land altering operations. The Permittee shall restore, to the standards in effect at the time of the issuance of the permit, sensitive areas, their buffers, and public and private properties and improvements damaged by the Permittee's operations. 3) Permittee shall arrange for and comply with the following: • Notify the Public Works Department within 48 hours following installation of ESC measures. ,,,,p a•1tt'pv+ttMftym" that lim i+ u° ymtf.%rC7`gro,'W?,74 Cet?I'XI PMpM A07, 07t".i e*RV:ih!y ru !CmlectL"mfrrl wor.l z • w 00 W 0: w w: J W O: 2 y g a co d i Z ,- o_ Z I- w uj o .

Applications When exposed soils are dry to the point that wind transport is possible and roadways, drainage ways or surface waters are likely to be impacted. Advantages • Reduces movement of soil to offsite areas. Disadvantages • Over watering, when water is used as dust control, may cause erosion. Design Criteria • Dust control is covered in the 00280 Supplemental. The designer can provide project - specific dust control specifications in the 00280 Special Provisions. • Dust control measures include: * Temporary stabilization practices such as temporary and permanent seeding, temporary mulching and erosion control blankets. * Sprinkling exposed areas with water. * Installing construction entrances and stabilizing construction haul roads. * Application of calcium chloride. Buffer Zone A buffer zone consists of an undisturbed area or strip of natural vegetation or an established suitable planting which reduces erosion and runoff. Applications • Between disturbed areas and streams or other water bodies. • Along natural swales and at wetlands. Advantages • Provide habitat. • Reduces velocity and quantity of runoff. • Provide visual screening. • Low maintenance.

Special Considerations • Constrains work area and equipment movement. • Requires the Inspector to fence or flag the clearing limits. • Requires the Inspector to fence or flag outside tree and shrub driplines. Design Criteria • Preserve natural vegetation in clumps, blocks or strips. • Preserve natural vegetation on unstable, sleep slopes. • Vegetative buffer zones for streams, lakes or other water ways should be 30 m wide on each side of the feature. The width can increase depending on other onsite conditions, existing vegetative conditions and erosion potential. Maintenance • Inspect flagging and fencing frequently and repair as needed. Preserve Natural Vegetation Preserving vegetation minimizes soil exposure and provides aesthetic benefits. Applications • Flood plains, wetlands, stream banks, steep slopes and other areas where erosion controls would be difficult to install and maintain. Advantages • Helps reduce soil erosion and runoff while beautifying an area. • Saves landscaping costs, provides areas for wildlife, and provides visual screening. • Helps maintain water temperature. Temperature moderation is especially important when detention ponds drain to salmonid- bearing streams. • Retains existing shade and cover habitat. Disadvantages • Retaining older trees could create a safety hazard. • May constrict area available for construction activities. Special Considerations • Requires coordination with Environmental Services Unit, Landscape Unit and the construction Project Manager's office. • Requires the Inspector to fence or flag the clearing limits. Chapter 1 Erosion Control Page 17 li N\LL w o: u. = w . z � � z I LLI u , U � o- o wW . z . w O F- z • Requires the Inspector to fence or flag outside tree and shrub driplines. Design Criteria • Contact the Landscape Architect when determining what to save and how to save it. • Vegetation can be preserved in natural clumps or as individual trees, shrubs and vines. • Clearly flag or mark the ground disturbance limits outside the dripline of preserved trees. • Protect vegetation from: * Construction equipment injury above or below the ground level. Injury occurs from scarring, cutting roots, or compaction. * Grade changes which affect the plants' ability to obtain air, water or minerals. Placing a layer of gravel and a tile system over the roots before a major fill allows air and protects the plant from the fill. * Root exposure. Terracing the area around the plant, or leaving the plants on an undisturbed mound can increase the plants' survival chances. * Damage caused by excavations for tile, water and sewer lines. Maintenance • Inspect and repair flagging or fencing. • Re -cover and /or seal exposed plant roots. Temporary and Permanent Seeding A well - established vegetative cover is one of the most effective methods of reducing erosion. Applications • On disturbed areas that require seeding either because the area has reached final grade (permanent seeding) or because the area will remain unworked from 2 to 12 months (temporary seeding). Refer to the 00280 Supplemental for soil exposure limitations and seeding dates. • In vegetation -lined channels, seed and then protect with a net or blanket. • In retention /detention ponds. Advantages • Prevents erosion and also traps sediment. • Improves appearance of the site. • Provides excellent stabilization. • Relatively inexpensive erosion control measure. Chapter 1 Erosion Control Page 18 Disadvantages • Needs sufficient time for seed to establish. • May require mulch or other cover. • May require fertilizer and lime to establish on poor soils. • May require irrigation. Design Criteria The following discussion presents general information regarding seeding, bed preparation, mulching and fertilizing. See the 00280 Supplemental for specific seeding requirements. Seed • Generally, the best time to permanently seed is early spring or late fall depending on site conditions. Mulching and irrigation may be required for areas seeded during the hot summer months. • Seed applied during the winter may take several months to develop a dense ground cover due to cold temperatures. The application and maintenance of mulch is critical for winter seeding. • To prevent seed from being washed away, confirm installation of all required surface water control measures. Seedbed • Prepare a firm but not compacted seedbed. Roughen slopes steeper than 1:3. The typical method is track- walking (driving a crawling tractor up and down the slope) creating cleat imprints parallel to the slope contours. Seed Mixes • Provide project - specific seed mixes and application rates in the 00280 Special Provisions. Fertilizer • Slow - release fertilizers are more efficient and have fewer environmental impacts.. Areas being seeded for final landscaping may require soil tests to determine the exact type and quantity of fertilizer needed to prevent the over - application of fertilizer. Use non - phosphorus fertilizer on disturbed areas near water bodies and wetlands. • The addition of stockpiled topsoil or compost reduces the need for fertilizer and improves the overall soil quality. • Provide project - specific application rates in the 00280 Special Provisions. Mulch • Required for seeding slopes greater than 1:3. • Required for seeding during the wet season. • May be required during the dry season if: * Grass growth is expected to be slow, Chapter 1 Erosion Control Page 19 I-Z w 0 N 0 co J = y' \ o ' ui = a 1-- _ Z F. Z o w w 0 to o— � o Ill ( I-V iii z — = . 0 ~' z • * The soils are highly erodible, * There is a water body close to the disturbed area, or * Significant precipitation is anticipated before the grass will provide effective cover. • Can be applied on top of the seed or applied with the seed during hydroseeding. z Z ` Hydroseed c • Hydroseeding requires a mulch tracer as a visual aid during application. ..1 • On slopes 1:1.5 and steeper, hydroseeding requires and tackifier. o. • During the dry season, hydroseeding with wood fiber mulch is adequate. w i • During the wet season, double the application rate to compensate for more -' rapid breakdown of the mulch. w o ga = a I- al z I I-O Z f- uj U O , 0 H IV W z = '_ 0 / z Maintenance • Reseed areas that fail to establish adequate cover within specified time. If reseeding is ineffective, use an alternate method, such as sodding or nets /blankets. • Reseed and protect with mulch any areas affected by erosion. If the erosion is caused by concentrated runoff, fix the runoff problem and then reseed and mulch the area. Mulch Mulching soils provides immediate temporary protection from erosion. Mulch also enhances plant establishment by conserving moisture, holding fertilizer, seed, and topsoil in place, and moderating soil temperatures. There are many varieties of mulch, only the most common types are discussed in this section. Applications • On areas which can't be seeded or are otherwise unfavorable for plant growth. • As a cover for seed during the wet season and during the hot summer months. • As temporary stabilization on bare soils exposed by construction activities. Refer to the 00280 Supplemental for specific requirements. Advantages • Provides instant protection. • Conserves moisture. • Does not require removal. • Allows vegetation growth through the mulch. • In all seasons, protects temporary and permanent seeding from heat, moisture loss and transport due to runoff and provides effective cover for seeding during the dry season. Chapter 1 Erosion Control Page 20 A Disadvantages • Must be applied at the specified thickness. • Thick mulches can delay germination. • Can be blown or washed away if not adequately secured. Design Criteria • Divert concentrated runoff from mulched slopes. • Specific material and application criteria are included in the 000280 Supplemental. The following discussion contains general information regarding mulches. Organic Mulches • Straw mulch provides immediate protection lasting approximately three months. Straw can be spread by hand or by machine and may require anchoring for wind protection. Common anchoring methods include crimping, disking, rolling or punching into the soil; covering with netting; spraying with a tackifier; or keeping it moist. Straw mulch is commonly used in Eastern Oregon in conjunction with seeding. • Corn Stalks, which decompose slowly and are resistant to windblow, should be shredded into 100 to 150 mm lengths. • Wood chips are suitable for areas . that will not be closely mowed and areas around ornamental plantings. Chips decompose slowly and require nitrogen application to prevent nutrient deficiency in plantings. Both wood and bark chips tend to wash down slopes greater than 6 %. • Wood cellulose, grass straw cellulose and paper fiber products are commonly used in western Oregon in a hydroseed slurry mix containing fertilizer. In Eastern Oregon the hydroseed slurry is used in conjunction with straw mulch to add protection from the sun. The combination of hydroseed slurry and straw mulch is well suited to steep slopes, critical areas and severe climate conditions. Wood fiber hydro - slurries, not containing seed or fertilizer, are used to tack straw mulch. • Manure mulches should be well -aged and are not suitable for use near water bodies. • Leaf compost, available in some areas of the state, is suitable for flat areas and steep slopes. Chemical Mulches Synthetic, spray -on mulches and soil binders can seal the soil surface, increasing erosion, and may cause adverse effects on water quality. Therefore, they are not recommended for use as a mulch. Chemical mulches may serve as tacking agents. Chapter 1 Erosion Control Page 21 z w 0 CO 0 CO • w COo w ga _ ° 1- w z � ►= z �-. U 0. 0 2 1- w ul - . `_ w z o~ z tr Maintenance • Maintain the thickness of the cover. • Remulch and /or protect with a net or blanket any areas that experience erosion. If the erosion problem is drainage related, then fix the drainage problem and remulch the eroded area. Sod Establishes permanent turf for immediate drainageways. erosion Applications • Disturbed areas requiring short -term or long -term cover. • Disturbed areas requiring immediate vegetative cover. • Waterways carrying intermittent flow (except biofiltration swales) and requiring immediate stabilization or aesthetic mitigation. Advantages • Provides immediate protection which is effective and aesthetically pleasing. • Provides high density vegetation which is superior to a recently seeded area. • Placement can occur any time that soil moisture is adequate and the ground is not frozen. Disadvantages • Expensive. • Difficult to find sod free of weeds. • Irrigation may be required if installed in summer. • Difficult to.mow if installed on slopes steeper than 1:3. • Installations in grassed waterways may roll up if not anchored or drained properly. 'Design Criteria • Use sod which is weed free, has uniform thickness (approximately 25 mm thick) and dense root mat for mechanical strength. • Generally inappropriate for bioswales. Sod can be used for lining ditches to prevent erosion, but will provide little water quality benefit during the wet season. • The following steps are general recommendations for sod installation. Refer to ODOT's Standard Specifications for specific installation criteria. • Shape and smooth the surface to final grade in accordance with the approved grading plan. • Fertilize as per supplier's recommendations. Some jurisdictions may require a non - phosphorous fertilizer near water bodies and wetlands. protection and stabilizes Chapter 1 Erosion Control Page 22 tW • Work lime and fertilizer into soil 25 -50 mm deep and smooth the surface. • Lay sod strips perpendicular to the direction of water flow, beginning at the lowest area to be sodded. Wedge strips securely into place and square the ends of each strip to provide for a close, tight fit. Stagger joints at least 300 mm. Staple sod onto 1:3 and steeper slopes. • Roll the sodded area and irrigate. • When sodding is carried out in alternating strips or other patterns, seed the areas between the sod immediately after sodding. Maintenance • Inspect sodded area frequently. • Retack, resod or reseed as necessary. • If it is impossible to establish a healthy ground cover due to frequent saturation, instability, or some other cause; remove the sod, seed the area with an appropriate mix, and protect with a net or blanket. Erosion Control Blankets Nets are strands of material woven into an open, but high - tensile strength net; for example, jute net). Mats are strands of material that are not tightly woven, but instead form a layer of interlocking fibers, typically held together by a biodegradable or photodegradable netting; for example, excelsior (wood fiber) or straw blankets.

Use organic blankets, which retain moisture and provide organic matter to the soil, for slope protection and short -term waterway protection and to improve the speed and success of revegetation. * Use jute netting in conjunction with mulch in order to prevent erosion that could result from the net's open structure. * Excelsior, woven straw, and coir blankets may be installed without mulch because they provide complete surface protection. • Synthetic mats are made from non - biodegradable material and will remain in place for years. Use purely synthetic blankets for long -term stabilization of waterways. * Turf Reinforcement Mats (TRM) are made from polymer nettings or monofilaments formed into a mat. TRMs protect seed and increase germination and also acts as part of the root structure; giving the turf higher strength. * Erosion Control and Revegetation Mats (ECRM), composed of heat -fused monofilaments or monofilaments stitched between netting act as permanent mulch.

J Construction Road/Parking Area Stabilization Stabilized parking areas and on -site vehicle transportation routes reduce erosion caused by construction traffic or runoff. Applications • Permanent or temporary roads or parking areas used by construction traffic. Advantages • Reduces onsite erosion, dust and off -site tracking of soils. • Can speed and enhance efficiency of onsite work. Disadvantages • Temporarily stabilized construction roads can be expensive to install and maintain. Design Criteria • Road and parking area stabilization may not be necessary during the dry season (unless dust is a concern) or if the site is underlain by coarse - grained soils. • ODOT usually leaves temporary road locations and construction criteria to the contractor's discretion. The following is general information regarding road and parking stabilization: • Stabilize roads and parking areas immediately after initial grading. • Whenever possible, construction roads and parking areas should be placed on firm, compacted subgrade. • Temporary road gradients shouldn't exceed 15 percent. • Grade roadways to encourage sheet flow runoff to a roadside ditch or to a heavily vegetated area, except vegetated wetlands or landscaped areas, with a well - developed topsoil and at least 15 m of vegetation to treat the sheet flow runoff. Treating sheet flow runoff from temporary roads is preferred to using a sediment pond or trap. • Immediately following grading, apply crushed rock, gravel base or crushed surfacing base course. A course of asphalt - treated base (ATB), cement or calcium chloride may also be used. • Install fencing, if necessary, to limit vehicle access to stabilized roads and parking areas. Maintenance • Add crushed rock, gravel base, as required to maintain a stable driving surface and to stabilize any eroded areas. Chapter 1 Erosion Control Page 29 z z re 00 CO W = N,LL. w O u.

Riprap Pod Or Equivalent Energy Dissipation Which Discharges To A Sediment Retention Measure Or A Stabilized Outlet. Figure 8 Pipe slope drain installation. Applications • On any slope where a temporary or permanent measure is needed to convey runoff to avoid erosion. Advantages • Effective method of conveying water down steep slopes. • Reduces or eliminates erosion. • Easy installation and little maintenance. Disadvantages • Drain can be under - designed or incorrectly located. • Area cleared for drain installation requires stabilization to prevent erosion occurring under the pipe. • Outfall systems constructed of pipe segments which are banded and /or gasketed together have developed leaks causing erosion and failure of the system. Failures on erodible or steep slopes can cause downstream sedimentation or even mudflows. Chapter 1 Erosion Control Page 30 z ~ w J U U U O. W = Jh- W u.

Consider site conditions to determine if a more complex energy dissipater may be required. Consult ODOT's FHWA's Hydraulic Design of Energy Dissipaters for Culverts and Channels as needed. Table 3 Slope Drain Sizes. • Consider using continuously fused, welded or flange - bolted mechanical joint systems with proper anchoring or HDPP (high density polyethylene pipe) for outfalls on steep slopes. • Show the entrance sloped toward the pipe inlet. the top of the inlet pipe and placed to direct water into the pipe. • The special provisions and the typical detail should include the following installation directions: 1. Minimize disturbance during installation. In some circumstances this requires HDPP installed by hand. 2. Immediately stabilize any area disturbed during installation or maintenance. 3. Securely connect the standard flared end section at the entrance to the slope drain, using watertight connecting bands. 4. Securely fasten together the slope drain sections with gasketed watertight fittings, and securely anchor the sections into the soil. 5. Stabilize the area below the outlet following the energy dissipater. Chapter 1 Erosion Control Page 31 Maintenance • Regularly check the inlet and outlet points, especially following heavy rains. If there are signs of undercutting or water is going around the point of entry, reinforce the head wall with compacted earth or sand bags. • Regularly check at connection points for signs of erosion. Tighten fittings and repair erosion as needed. • immediately repair and install appropriate protection if erosion occurs at the outlet. Interceptor Dike and Interceptor Swale A ridge of compacted soil or a lined swale with vegetative lining located at the top, base or somewhere along a sloping disturbed area. The dike or swale intercepts and conveys smaller flows along low- gradient drainage ways to larger conveyances such as ditches or pipe slope drains or to a stabilized outlet.

Be sure to remove rock which was carried downstream. • Seed and mulch the area where the check dams were immediately following removal. Maintenance • Periodically inspect check dams for performance and sediment accumulation. • Remove sediment once it reaches one -half the sump depth. Chapter 1 Erosion Control Page 36 1 Outlet Protection Outlet protection reduces the speed of concentrated flow; thereby, preventing scour at conveyance outlets. By dissipating energy, outlet protection lowers the potential for downstream erosion. Outlet protection includes riprap -lined basins, concrete aprons, and settling basins. PC AN Figure 11 Common outlet protection techniques. Advantages • Many techniques are effective and relatively inexpensive and easy to install . • Removes sediment and reduces velocity. Applications • At the outlets of ponds, pipe slope drains, ditches,.or other conveyances, and where runoff is conveyed to a natural or man -made drainage feature such as a stream, wetland, lake, or ditch. Disadvantages • Can be unsightly. • May be difficult to remove sediment without removing and replacing the structure itself. Chapter 1 Erosion Control Page 37 • Rock outlets with high velocity flows may require frequent maintenance. Design Criteria • Refer to FHWA's Hydraulic Design of Energy Dissipators for Culverts and Channels, Hydraulic Engineering Circular No. 14, September, 1983 or Design of Roadside Channels with Flexible Linings; Hydraulic Engineering Circular No. 15, April 1988, for specific criteria. Maintenance • If there is scour at the outlet, protect the eroded area with more conservative measures. Silt Fence Temporary sediment trap consisting of an entrenched geotextile stretched across and attached to supporting posts. Silt fences are adequate to treat flow depths consistent with overland or sheet flow. Supported silt fence consists of geotextile backed with wire or polymeric mesh supported by metal posts. Unsupported silt fence does not have mesh backing and may be supported by wood stakes. Refer to the 00280 Supplemental Standard Specifications for more specific information.

Advantages • Relatively inexpensive method of sediment control. Disadvantages • Effective approximately 3 months. • Misuse or incorrect installation can contribute to sediment loading. • Difficult to tell if bales are properly installed. • Straw bale barriers have not performed as effectively as originally expected. There are three major reasons for such ineffectiveness: 1. Improper applications; installations in drainageways and swales where high water volumes and velocities destroyed effectiveness. 2. Improper placement and /or installation has allowed undercutting and end - flow. 3. Inadequate maintenance which can reduce effectiveness of sediment removal anywhere from 16% to 57% in one month. Design Criteria A formal design is not required. Sheet Flow • Contributing drainage should be less than 0.3 hectare per 100 meters of bale length. • On the typical details show: * bales embedded 100 to 150 mm, with bale ends tightly abutted and chinked with straw between bales. * bales bound around the long direction of the bale and placed so the binding is not in contact with the soil. * downhill side backfilled with excavated soil. * bales securely anchored with rebar or wood stakes. * Aggregate between bales at low points or every 30 meters (to allow release of ponded water).

Design Criteria • Assess the impacts of allowing water to pond at the inlet and provide an overflow weir or some other type of relief as needed. • Consider the effect placing obstructions at inlets on grade may have on their efficiency. Refer to ODOT's Hydraulic Manual or contact the Hydraulics Unit when placing protection at several inlets on grade along a roadway section. • When possible, include a sediment sump 300 to 600 mm deep with 1:4 side slopes. * Silt Fence Inlet Protection - At non -paved inlets below drainages having less than a 5% slope. Provide a sump. * Gravel and Wire Mesh Inlet Protection - Applicable for inlets in construction traffic areas which receive flows greater than 0.014 m /sec. * Catch Basin Insert Inlet Protection - At inlets below drainages flatter than 5% slope. The filter material should retain sediment 0:6 mm and larger, while allowing the runoff to pass at or near the inlet's design flow rate. Maintenance • Do not use water to remove sediment. • Remove sediment accumulated on or around the protection as needed to maintain intended functions. • Repair or replace materials as needed to ensure proper functioning.

The designer may want to route surface water collected from disturbed w I 0 w areas of the site through a sediment trap prior to release from the site. IL Lll • May become an attractive nuisance. Care must be taken to adhere to all safety o i practices. Z • Maintenance and sediment removal is essential for adequate performance. • Serves limited areas. • Does not reduce turbidity resulting from fine silts and clays in runoff. Traps are ' more effective when used in conjunction with other measures such as seeding and mulching. Disadvantages Design Criteria • Temperature moderation is especially, important when a sediment trap drains to salmonid- bearing streams. • Construct prior to any upslope clearing and grading. • Locate in a low area where the trap will intercept all or most of the runoff from the disturbed area before it enters a waterway, considering safety in case structure fails. • Locate the trap so that it is readily accessible for maintenance. Chapter 1 Erosion Control Page 47 • Provide for diversion dikes and ditches, as needed, to collect and divert water toward the trap. • Design the trap with a level bottom, 1:3 or flatter side slopes and a L:W ratio of 3. Because sediment traps are temporary, the sizing is less important to proper functioning than is constant maintenance. 1. Calculate the Storage Volume (V), using 252 cubic meters of storage per hectare of drainage area. Divide the storage evenly between dry and wet storage. For limited space situations, the designer may use a minimum calculation of 126 cubic meters per hectare of drainage. 2. Calculate the trap dimensions using the following: V = [3W + [4WZD + [4/3Z Where: 3. Calculate the trap length using: L = 3W V = Storage Volume W = Width of Trap D = Depth of Trap (Maximum dry storage depth of 1.5 meters) Z = Side slope (1:Z; vertical to horizontal) 4. Approximate the volume in a natural storage area using the following. Surface area and maximum depth depend on site conditions. Volume = (0.4) (surface area) (maximum depth). • Provide a rock weir (spillway) or perforated riser pipe as outlet to the trap. The crest of the weir should be 0.3 meters below the top of the embankment. The weir can be constructed of two layers of different size rock or one depth of 150 mm and smaller riprap. Size the rock for stability during expected flows. • Figure 17 is a riser pipe outlet typical detail developed by FHWA. A typical detail for the riser pipe should show the following: * Pipe perforations which are 13 mm wide by 150 mm long slits or 25 mm diameter holes spaced 150 mm vertically and horizontally above the wet storage elevation. * The riser pipe should be wrapped with 6.4 to 13.0 mm wire hardware cloth and covered with geotextile which is overlapped, folded and fastened at the seam. The geotextile should extend 150 mm above and below the highest and lowest slits and should be secured top and bottom with straps or connecting bands.

If the trap is formed by embankment, the designer should note that dam safety regulation may apply to heights exceeding 1.5 meters. The embankment should be stabilized using a cover method such as seeding, mulching or erosion control matting. • Require installation of a staff gauge to aid in determining sediment depth.

Water temperature in the trap may be too high for direct release. Always moderate the water temperature before it drains into a lake, stream, wetland or waterway. Whenever possible, release the trap discharge onsite onto a relatively level, densely - grassed area at least 20 meters from a water way or wetland. • Evaluate the release areas on a site- byeite basis in order to determine appropriate locations for and methods of releasing runoff. Do not use vegetated wetlands for this purpose. Refer to FHWA Hydraulic Design of Energy Dissipators for Culverts and Channels. Maintenance • Constant maintenance is essential for proper functioning. • Remove sediment from the trap when it reaches 0.3 m in depth. • Repair any damage to the trap, the embankments or the slopes.

The sediment basin serves drainage areas less than 4 hectares and has a design life of approximately 1 -year. Basins are large facilities which treat runoff from large drainage areas. Because of this, basins have limited application to highway construction projects. The applications, advantages and disadvantages of basins are included here for the designer's edification. For specific design information please refer to Best Management Practices for Erosion and Sediment Control, Report No. FHWA- FLP -94 -005 written by the U.S. Department of Transportation. • Do not drain basins directly into a stream, lake, wetland or other waterway. Water temperature in the basin may be too high for direct release. Always moderate the water temperature before it drains into a lake, stream or waterway. Whenever possible, release the trap discharge onsite onto a relatively level, densely- grassed area at least 20 meters from a water way or wetland. Applications • Drainage areas from 2 to 4 hectares. • Sites in proximity to salmonid streams, wetlands, or phosphorus- sensitive waterbodies. • Sites where major clearing and•grading is likely to occur during the wet season. • Sites with downstream erosion or sedimentation problems. • Downslope of disturbed areas. Install prior to any upslope clearing and grading. • Combining with Permanent Drainage Facilities 0 If a project includes a permanent storm water retention /detention pond, the rough - graded or final - graded facility could function as a basin during construction. Design features of the permanent structure, such as surface area, retention time and outlet control, should meet the design requirements of the temporary facility. Completion of the permanent facility should occur only when all upstream control structures are in place and stabilization of contributing drainage areas is complete. 0 If a project includes an infiltration facility, the roughly excavated facility could be used as a basin, providing the facility provides the surface area and retention time required by the basin. Excavate the sides and bottom of the facility to a minimum of 0.6 m above final grade with a backhoe working at "arms length" to minimize disturbance and compaction of the infiltration surface. 0 Additionally, any required pretreatment facilities should be fully constructed prior to any release of sediment -laden water to the facility. Pretreatment and shallow excavation are intended to prevent the clogging of soil with fines.

Keystar, Inc. recently replaced the old 4" water line along South 126th Street and installed an 8" water line. Two new fire hydrants were also instal ed; one at the intersection of S.126th Street/40th Ave. South and the other at the intersection of South 126th Street/41st Ave. South. The updated Water Availability Certificate reflects these improvements. Residential permit conditions included a provision that proof of fire flow be provided the Fire Marshal prior to combustibles( i.e. wood for framing) be brought on site for building construction. We understand that Russ Austin, Water District 125, and you discussed that this updated Water Availability Certificate would meet your requirement that fire flow was available. Keystar, Inc. is scheduling wood delivery to the site to commence house framing. We believe with this transmittal of Certificate of Water Availability, Keystar, Inc. has met the Building Permit Condition and the Fire Marshal requirement. Please call Robert Parnell at 425/643 -3560 or Fax 425/641 -5095 to confirm receipt and that the fire flow data transmitted meets permit conditions to allow combustibles to be brought onto sites.

Some of the conditions apply to erosion prevention and sediment control. Keystar is not meeting these conditions. A summary of the City's erosion prevention and sediment control requirements and a copy of the permit conditions is enclosed. Keystar installed silt fence as perimeter protection, but has not maintained the fencing. In addition, in some locations the silt fence is being used more as a retaining wall, which is contrary to its intended use. None of the unworked areas have cover measures.

Construction should follow by. early September with completion by the late September. The 8 "sanitary sewer extension would follow approximately the same schedule with the ValVue Sewer District. Upon water and sewer developer extension completion, we would provide water and sewer availability. We understand that for lots 5 -10, you require 20 foot of paved surface section of 5" Class B asphalt underlain with 3" compacted top course. We understand the individual lot driveways are acceptable. I have included the Typical Downspout Infiltration System Detail and the Residential Driveway Detail (RS8B) on the Utilities Site Plan.

Per Jim Morrow, Public Works Director, Public Works will not approve the single family residence (SFR) applications until the water and sewer are installed. Public Works may consider approving the permits once the water and sewer work is underway. Public Works requires a sewer and a water availability letter PER LOT, once the water and sewer are installed. Even though Keystar has not applied for the short plat, several of the requirements for the short plat should be taken into consideration when Steven M. Mullet, Mayor RECEIVED CITY OF TUKWILA JUN - 2 2000 PERMIT CENTER 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206-433-0179 • Fax: 206- 431 -3665 ,;' May 21, 2000 Page 2 developing Lots A and H. These are: • Five foot wide right of way dedication along 40 Ave. S. • Fire turn around • Street improvements Public Works will require a legal description, statutory warranty deed and a completed and signed excise tax form for the five -foot wide right of way dedication as part of the short plat process. These documents are not necessary for the SFR applications. Keystar can ignore the short plat preapplication requirement for combined driveways. Brian Shelton, City Engineer, will allow individual driveways for each lot. For lots 5 -10 and Lots A -H applications, the City requires 20 feet of paved surface on 40 Ave S. and S. 126 St. Per Brian Shelton, the pavement section shall be 5" of Class B asphalt, underlain with 3" compacted top course, underlain by additional gravel, depth determined by site conditions.

Keefe, Fire Chief Brenda Holt, Permit Coordinator Jim Morrow, Director of Public Works FROM: Mike Alderson, Fire Marshal SUBJECT: Keystar Building Permits DATE: 6/9/00 RE: Building Permits; D2000 -035, D2000 -036, D2000 -037, D2000 -038, D2000 -039, D2000 -077 and D2000 -078 It has been brought to my attention that the Certificates of Water Availability submitted with the referenced Building Permit Applications stipulated that a flow of 880 GPM would be available "after" the upgrade of the existing 4" water main to an 8" line. The Uniform Fire Code, Appendix IIIA, requires a minimum fire flow of 1,000 Gallons Per Minute be available for single family dwellings. The code allows for a 50% reduction in flow requirement when the dwelling has a sprinkler system installed. These requirements are a condition for the issuance of a Building Permit. In this case, the existing Hydrant has a flow of less than 500 gpm, which does not allow construction permits to be issued. The referenced Permits are not to be issued until the improvements identified in the Certificate of Water Availability are completed. The building of numerous residences on small lots close together creates a severe fire hazard during the construction phase. The limited available fire flow would make extinguisment of a fire among unprotected wood frame structures near impossible. This is one of the reasons the code does not allow Building Permits to be issued where there is limited flow. Steven M.
