Soil erosion and resulting sedimentation are a leading cause of water quality problems. Although erosion has long been associated with farming activities, it is also `a major concern at construction sites, if the disturbed land is left unprotected. 2.2 Primary Concerns Related to Erosion and Sedimentation ' • Water Quality. Sediment is a major pollutant of surface water in the state of California. It impacts water quality by degrading the habitat of aquatic Erosion Control Plan 43 Dacy Ave., Cohasset, CA 3 June 2004 organisms and fish, by decreasing recreational value, and by promoting the growth of nuisance weeds and algae. • Local Costs. Sediment that finds its way into streets, storm sewers, and ditches results in additional maintenance costs for local government. • Flooding. Sediment accumulation in streams, lakes, and rivers reduces their capacity, which can result in increased flooding. • Property Values. Sediment deposits not only impair water quality but also damage property, thus reducing its use and value. SECTION 3: PROJECT DESCRIPTION 3.1 Project Description The project consists of installation of 150 linear feet of septic leach lines and construction of a 1,228 square -foot addition to a residence located at 43 Dacy Ave., Cohasset, Butte County, CA. 3.2 Unique Site Features None. 3.3 Project Schedule Estimated construction start: Estimated construction finish: 3.4 Contact Information Ms. Donna Carr 43 Dacy Ave. Cohasset, CA 95973 (530) 893-2648 SECTION 4: BODY OF ECP 4.1 Objectives June 2004 November 2004 The object of the ECP is to identify, construct, implement in accordance with a time schedule, and maintain Best Management Practices (BMPs) ' to reduce or eliminate pollutants (including sediment) in storm water discharges and authorized non -storm water discharges from the construction site during construction. 4.2 Site Map The construction project site map is located in Attachment A. Erosion Control Plan 43 Dacy Ave., Cohasset, CA 3 June 2004 4.3 BMP Selection 4.3.1 Inventory of Activities that May Pollute Storm Water Construction activities that have the potential to contribute sediment to storm water discharges include: • Clear and grub operations • Utility excavation operations Attachment B lists all BMPs that have been selected for implementation of this project. Copies of the fact sheets of all the BMPs selected for this project are included. 4.3.2 Erosion Control Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to prevent soil particles from detaching and becoming transported in storm water runoff. Erosion control BMPs protect the soil surface by covering and/or binding soil particles. This project will implement the following practices for effective temporary and final erosion control during construction: • Schedule construction activities outside of defined rainy season to reduce erosion potential. o Monitor the weather using National Weather Service reports to track conditions and alert crews to the onset of rainfall events. ■ Deploy and inspect temporary erosion control BMPs prior to forecast storm events. • Preserve existing vegetation where required and feasible. • Cover stockpiles with plastic sheeting or geotextiles. • Implement temporary erosion control measures at regular intervals throughout the defined rainy season to achieve and maintain the contract's disturbed soil area requirements. Implement erosion control prior to the defined rainy season. • Stabilize non-active_ areas as soon as feasible after the cessation of construction activities. • At completion of construction, apply permanent erosion control to all remaining disturbed soil areas. The BMP Consideration Checklist in Attachment B indicates all or a combination of the BMPs that will be implemented to control erosion on the construction site; these are: • EC -1, Scheduling • EC -2, Preservation of Existing Vegetation • EC -6, Straw Mulch e• EC -7, Geotextiles and Mats Erosion Control Plan 43 Dacy Ave., Cohasset, CA 3 June 2004 BMPs will be deployed in sequence to follow the progress of construction. As the locations of soil disturbance change, erosion and sedimentation controls will be adjusted accordingly to control storm water runoff at the downgrade perimeter and drain inlets. 4.3.3 Sediment Control Sediment controls are structural measures that are intended to complement and enhance the selected erosion control measures and reduce sediment discharges from active construction areas. Sediment controls are designed to intercept and settle out soil particles that have been detached and transported by the force of water. This project will incorporate sediment control measures required by the contract documents, and other measures selected by the Owner. Sufficient quantities of temporary sediment control materials will be maintained on-site throughout the duration of the project, to allow implementation of temporary sediment controls in the event of predicted rain, and for rapid.response to failures or emergencies. This includes implementation requirements for active areas and non-active areas before the onset of rain. This project will implement the following practices for effective sediment control during construction: • Implement temporary sediment controls (i.e., fiber rolls, straw bales) at the draining perimeter of disturbed soil areas and at storm drains downstream from disturbed areas prior to beginning any earth -moving activities. • Sweep or vacuum visible sediment tracking on a daily basis; do not flush area with water. The BMP Consideration Checklist in Attachment B indicates all or a combination of the BMPs that will be implemented to control sediment on the construction site; these are: ' • SE -1, Silt fence • SE -5, Fiber rolls • SE -6, Gravel bag berm `. • SE -7, Street sweeping and vacuuming • SE' -8, Sand bag barrier ' • 5E-9, Straw bale barrier • 5E-10, Storm drain inlet protection ' During the rainy season, temporary sediment controls will be implemented at the draining perimeter of disturbed soils areas, at the toe of slopes, at storm drain inlets and at outfall areas at all times. During the non -rainy season temporary 'sediment controls will be implemented' at the draining perimeter of disturbed soil areas and at storm drains downstream from disturbed ' areas before rain events. In the event of a predicted storm, the following temporary sediment controls will be maintained on-site: straw bale linear barriers, fiber rolls. Erosion Control Plan 43 Dacy Ave., Cohasset, CA ' 3 June 2004 4.3.4 Tracking Control A stabilized construction access is defined by a point of entrance/exit to a construction site that is stabilized to reduce the tracking of mud and dirt onto public roads by construction vehicles. On-site vehicle transportation routes should be stabilized. This project will implement the following practices for effective tracking control during construction: • Graveled on-site transportation route and construction entrance already in place associated with the residential structure. The BMP Consideration Checklist in Attachment B indicates all or a combination of the BMPs that have been selected to reduce sediment tracking from the construction site onto private or public roads: • SE -7, Street sweeping and vacuuming • TC -1, Stabilized construction entrance/exit • TC -2, Stabilized construction roadway • TC -3, Entrance/Outlet tire wash 4.4 Construction BMP Maintenance, Inspection, and Repair Inspections will be conducted as follows: • Prior to a forecast storm; • After a rain event that causes runoff from the construction site; • At 24-hour intervals during extended rain events; • Weekly during the rainy season; • Every two weeks during the non -rainy season. 4.5 Soil Disposal No leveling or grading will be .required at the building site. Soil spoils incurred during the construction project will be stockpiled approximately 300 feet east of the building site and away from any downslope street, driveway, or drainage way (see Site Map in Appendix A). A portion of this material will be used to backfill .the septic. leach field area. The remaining material will be spread out to rough grade at a depth of 4 to 6 inches in the general area of the stockpile, wetted, and covered with straw mulch (e.g. a spade or shovel will be used to punch in the straw mulch), using 1 '/2 to 2 bales of straw per 1,000 square feet, to encourage natural re -vegetation. 4.6 Subcontractors All contractors and subcontractors will be notified of the requirement for storm water management measures during the project.

Suitable Applications Preservation of existing vegetation is suitable for use on most projects. Large project sites often provide the greatest opportunity for use of this BMP. Suitable applications include the following: ■ Areas within the site where no construction activity occurs, or occurs at a later date. This BMP is especially suitable to multi year projects where grading can be phased. ■ Areas where natural vegetation exists and is designated for preservation. Such areas often include steep slopes, watercourse, and building sites in wooded areas. ' ■ Areas where local, state, and federal government require preservation, such as vernal pools, wetlands, marshes, certain oak trees, etc. These areas are usually designated on ' the plans, or in the specifications, permits, or environmental documents. ■ Where vegetation designated for ultimate removal can be temporarily preserved and be utilized for erosion control and sediment control.

Implementation The best way to prevent erosion is to not disturb the land. In order to reduce the impacts of new development and redevelopment, projects may be designed to avoid disturbing land in sensitive areas of the site (e.g., natural watercourses, steep slopes), and to incorporate unique or desirable existing vegetation into the site's landscaping plan. Clearly marking and leaving a buffer area ' around these unique areas during construction will help to preserve these areas as well as take advantage of natural erosion prevention and sediment trapping. ' Existing vegetation to be preserved on the site must be protected from mechanical and other injury while the land is being developed. The purpose of protecting existing vegetation is to ensure the survival of desirable vegetation for shade, beautification, and erosion control. ' Mature vegetation has extensive root systems that help to hold soil in place, thus reducing erosion. In addition, vegetation helps keep soil from drying rapidly and becoming susceptible to erosion. To effectively save existing vegetation, no disturbances of any kind should be allowed within a defined area around the vegetation. For trees, no construction activity should occur within the drip line of the tree. 74ming ' ■ Provide for preservation of existing vegetation prior to the commencement of clearing and grubbing operations or other soil disturbing activities in areas where no construction activity is planned or will occur at a later date. ' Design and Layout ■ Mark areas to be preserved with temporary fencing. Include sufficient setback to protect roots. - Orange colored plastic mesh fencing works well. ' - Use appropriate fence posts and adequate post spacing and depth to completely support the fence in an upright position. ■ Locate temporary roadways, stockpiles, and layout areas to avoid stands of trees, shrubs, ' and grass. ■ Consider the impact of grade changes to existing vegetation and the root zone. ' ■ Maintain existing irrigation systems where feasible. Temporary irrigation may be required. ■ Instruct employees and subcontractors to honor protective devices. Prohibit heavy equipment, vehicular traffic, or storage of construction materials within the protected area. 2 of 4 California Stormwater BMP Handbook January 2003 Construction www.cabmphand,books.com Preservation Of Existing vegetation EC -2 Costs. There is little cost associated with preserving existing vegetation if properly planned during the project design, and these costs may be offset by aesthetic benefits that enhance property values. During construction, the cost for preserving existing vegetation will likely be less than the cost of applying erosion and sediment controls to the disturbed area. Replacing vegetation inadvertently destroyed during construction can be extremely expensive, sometimes in excess of $1o,000 per tree. ■ Inspection and Maintenance During construction, the limits of disturbance should remain clearly marked at all times. Irrigation or maintenance of existing vegetation should be described in the landscaping plan. If r damage to protected trees still occurs, maintenance guidelines described below should be followed: ■ Verify that protective measures remain in place. Restore damaged protection measures immediately. ' d ■ Serious tree injuries shall be attended to by an arborist. ■ Damage to the crown, trunk, or root system of a retained tree shall be repaired immediately. ' ■ Trench as far from tree trunks as possible, usually outside of the tree drip line or canopy. Curve trenches around trees to avoid large roots or root concentrations. If roots are encountered, consider tunneling under them. When trenching or tunneling near or under ' trees to be retained, place tunnels at least 18 in. below the ground surface, and not below the tree center to minimize impact on the roots. ' ■ Do not leave tree roots exposed to air. Cover exposed roots with soil as soon as possible. If soil covering is not practical, protect exposed roots with wet burlap or peat moss until the tunnel or trench is ready for backfill. ' ■ Cleanly remove the ends of damaged roots with a smooth cut. ■ Fill trenches and tunnels as soon as possible. Careful filling and tamping will eliminate air ' spaces in the soil, which can damage roots. ■ If bark damage occurs, cut back all loosened bark into the undamaged area, with the cut tapered at the top and bottom and drainage provided at the base of the wood. Limit cutting ' the undamaged area as much as possible. ■ Aerate soil that has been compacted over a trees root zone by punching holes 12 in. deep ' with an iron bar, and moving the bar back and forth until the soil is loosened. Place holes 18 in. apart throughout the area of compacted soil under the tree crown. ■ Fertilization - Fertilize stressed or damaged broadleaf trees to aid recovery. Fertilize trees in the late fall or early spring. ' January 2003 California Stormwater BMP Handbook 3 of 4 Construction www.cabmphandbooks.com a E EC -2 Preservation Of Existing Vegetation ' - Apply fertilizer to the soil over the feeder roots and in accordance with label instructions, but never closer than 3 ft to the trunk. Increase the fertilized area by one-fourth of the crown area for conifers that have extended root systems. ' ■ Retain protective measures until all other construction activity is complete to avoid damage during site cleanup and stabilization.

Straw mulch protects the soil surface from the impact of rain drops,preventing soil particles from becoming dislodged. Suitable Applications Straw mulch is suitable for soil disturbed areas requiring temporary protection until permanent stabilization is established. Straw inulch is typically used for erosion control on disturbed areas until soils can be prepared for permanent vegetation. Straw mulch is also used in combination with temporary and/or permanent seeding strategies to enhance plant establishment. Limitations e Availability of straw and straw blowing equipment maybe limited just prior to the rainy season and prior to storms due to high demand. N There is a potential for introduction of weed seed and unwanted plant material.

Implementation ' ■ Straw shall be derived from wheat, rice, or barley. Where required by the plans, specifications, permits, or environmental documents, native grass straw shall be used. ■ A tackifier is the preferred method for anchoring straw mulch to the soil on slopes. ■ Crimping, punch roller -type rollers, or track walking may also be used to incorporate straw mulch into the soil on slopes. Track walking shall only be used where other methods are impractical. ■ Avoid placing straw onto roads, sidewalks, drainage channels, sound walls, existing vegetation, etc. ■ Straw mulch with tackifier shall not be applied during or immediately before rainfall. ■ In San Diego, use of straw near wood framed home construction has been frowned on by the Fire Marshall. Application Procedures ■ Apply straw at a minimum rate of 4,000 lb/acre, either by machine or by hand distribution. ■ Roughen embankments and fill rills before placing the straw mulch by rolling with a crimping or punching type roller or by track walking. ■ Evenly distribute straw mulch on the soil surface. ■ Anchor straw mulch to the soil surface by "punching" it into the soil mechanically (incorporating). Alternatively, use a tackifier to adhere straw fibers. ■ Methods for holding the straw mulch in place depend upon the slope steepness, accessibility, soil conditions, and longevity. On small areas, a spade or shovel can be used to punch in straw mulch. - On slopes with soils that are stable enough and of sufficient gradient to safely support construction equipment without contributing to compaction and instability problems, straw can be "punched" into the ground using a knife blade roller or a straight bladed coulter, known commercially as a "crimper". - On small areas and/or steep slopes, straw can also be held in place using plastic netting or jute. The netting shall be held in place using ii gauge wire staples, geotextile pins or wooden stakes as described in EC -7, Geotextiles and Mats. - A tackifier acts to glue the straw fibers together and to the soil surface.

Application by hand is more time intensive and potentially costly. 'Inspection and Maintenance ! ■ Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non -rainy season. ■ Areas where erosion is evident should be repaired and BMPs re-applied as soon as possible. Care should be exercised to minimiie the damage to protected areas while making repairs, as any area damaged will require re-application of BMPs. ■ The key consideration in inspection and maintenance is that the straw needs to last long enough to achieve erosion control objectives. ■ Maintain an unbroken, temporary mulched ground cover while disturbed soil areas are inactive: Repair any damaged ground cover and re -mulch exposed areas. ■ Reapplication of straw mulch and tackifier may be required to maintain effective soil stabilization over disturbed areas and slopes.

January 2003 California Stormwater BMP Handbook 3 of 3 Construction www.cabmphandbooks.com Geotextiles and Mats Description and Purpose Mattings of natural materials are used to cover the soil surface to reduce erosion from rainfall impact, hold soil in place, and absorb and hold moisture,near the soil surface. Additionally, matting may be used to stabilize soils until vegetation is established. Suitable Applications Mattings are commonly applied on short, steep slopes where erosion hazard is high and vegetation will be slow to establish. Mattings are also used on stream banks where moving water at velocities between 3 ft/s and 6 ft/s'are likely to wash out new vegetation, and in areas where the soil surface is disturbed and where existing vegetation has been removed. Matting may also be used when seeding cannot occur (e.g., late season construction and/or the arrival of an early rain season). Erosion control matting should be considered when the soils are fine grained and potentially erosive. These measures should be considered in the following situations. ■ Steep slopes, generally steeper than 3:1(H:V) ■ Slopes where the erosion potential is high ■ Slopes and disturbed soils where mulch must be anchored EC -7 I Objectives EC Erosion Control ✓ 00 Sediment Control 00 Tracking Control 00 .

' This high cost typically limits the use of mattings to areas of concentrated channel flow and steep slopes. ' ■ Mattings are more costly than other BMP practices, limiting their use to areas where other BMPs are ineffective (e.g. channels, steep slopes). ' ■ Installation is critical and requires experienced contractors. The contractor should install the matting material in such a manner that continuous contact between the material and the soil occurs. ' ■ Geotextiles and Mats may delay seed germination, due to reduction in soil temperature. ■ Blankets and mats are generally not suitable for excessively rocky sites or areas where the ' final vegetation will be mowed (since staples and netting can catch in mowers). ■ Blankets and mats must be removed and disposed of prior to application of permanent soil stabilization measures. ■ Plastic sheeting is easily vandalized, easily torn, photodegradable, and must be disposed of at a landfill. t■ Plastic results in l00% runoff, which may cause serious erosion problems in the areas receiving the increased flow. ■ The use of plastic should be limited to covering stockpiles or very small graded areas for short periods of time (such as through one imminent storm event) until alternative measures, such as seeding and mulching, may be installed. ' ■ Geotextiles, mats, plastic covers, and erosion control covers have maximum flow rate limitations; consult the manufacturer for proper selection. ■ Not suitable for areas that have heavy foot traffic (tripping hazard) — e.g., pad areas around buildings under construction. ' Implementation Material Selection Organic matting materials have been found to be effective where re -vegetation will be provided ' by re -seeding. The choice of matting should be based on the size of area, side slopes, surface conditions such as hardness, moisture, weed growth, and availability of materials. 2 of 11 California Storm -water BMP Handbook January 2003 Construction www.cabmphandbooks.com Geotextiles and Mats EC -7 ' The following natural and synthetic mattings are commonly used: Geotextiles ■ Material should be a woven polypropylene fabric with minimum thickness of 0.06 in., ' minimum width of 12 ft and should have minimum tensile strength of 150 lbs (warp), 80 lbs (fill) in conformance with the requirements in ASTM Designation: D 4632.

The material is furnished in rolled strips, which must be secured with U-shaped staples or stakes in accordance with manufacturers' recommendations. Site Preparation ■ Proper site preparation is essential to ensure complete contact of the blanket or matting with the soil. ■ Grade and shape the area of installation. ■ Remove all rocks, clods, vegetation or other obstructions so that the installed blankets or mats will have complete, direct contact with the soil. ■ Prepare seedbed by loosening 2 to 3 in. of topsoil. Seeding Seed the area before blanket installation for erosion control and revegetation. Seeding after mat installation is often specified for turf reinforcement application. When seeding prior to blanket January 2003 California Stormwater BMP Handbook 5 of 11 Construction www.cabmphandbooks.com EC -7 Geotextiles and Mats ' installation, all check slots and other areas disturbed during installation must be re -seeded. Where soil filling is specified, seed the matting and the entire disturbed area after installation and prior to filling the mat with soil. ' Fertilize and seed in accordance with seeding specifications or other types of landscaping plans. When using jute matting on a seeded area, apply approximately half the seed before laying the ? mat and the remainder after laying the mat. The protective matting can be laid over areas where grass has been planted and the seedlings have emerged. Where vines or other ground covers are to be planted, lay the protective matting first and then plant through matting according to design of planting. Check Slots Check slots are made of glass fiber strips, excelsior matting strips or tight folded jute matting blanket or strips for use on steep, highly erodible watercourses. The check slots are placed in narrow trenches 6 to 12 in. deep across the channel and left flush with the soil surface. They are to cover the full cross section of designed flow. Laying and Securing Matting ■ Before laying the matting, all check slots should be installed and the friable seedbed made free from clods, rocks, and roots. The surface should be compacted and finished according to the requirements of the manufacturer's recommendations. ■ Mechanical or manual lay down equipment should be capable of handling full rolls of fabric and laying the fabric smoothly without wrinkles or folds. The equipment should meet the fabric manufacturer's recommendations or equivalent standards. Anchoring ■ U-shaped wire staples, metal geotextile stake pins, or triangular wooden stakes can be used to anchor mats and blankets to the ground surface. ■ Wire staples should be made of minimum 11 gauge steel wire and should be U-shaped with 8 in. legs and 2 in. crown. ■ Metal stake pins should be 0.188 in. diameter steel with a 1.5 in. steel washer at the head of the pin, and 8 in. in length. ■ Wire staples and metal stakes should be driven flush to the soil surface. , Installation on Slopes Installation should be in accordance with the manufacturer's recommendations. In general, these will be as follows: ■ Begin at the top of the slope and anchor the blanket in a 6 in. deep by 6 in. wide trench. Backfill trench and tamp earth firmly. ■ Unroll blanket down slope in the direction of water flow. ■ Overlap the edges of adjacent parallel rolls 2 to 3 in. and staple every 3 ft. 6 of 11 California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com n Geotextiles and Mats EC -7 ' ■ When blankets must be spliced, place blankets end over end (shingle style) with 6 in. overlap. Staple through overlapped area, approximately 12 in. apart. ■ Lay blankets loosely and maintain direct contact with the soil. Do not stretch. ' ■ Staple blankets sufficiently to anchor blanket and maintain contact with the soil. Staples should be placed down the center and staggered with the staples placed along the edges. Steep slopes, 1:1 (H:V) to 2:1 (HY), require a minimum of 2 staples/yd2. Moderate slopes, 2:1 (H:V) to 3:1 (H:V), require a minimum of 1 1/2 staples/yd2. Installation in Channels ' Installation should be in accordance with the manufacturer's recommendations. In general, these will be as follows: ■ Dig initial anchor trench 12 in. deep and 6 in. wide across the channel at the lower end of the project area. ■ Excavate intermittent check slots, 6 in. deep and 6 in. wide across the channel at 25 to 30 ft intervals along the channels. ■ Cut longitudinal channel anchor trenches 4 in. deep and 4 in. wide along each side of the ' installation to bury edges of matting, whenever possible extend matting 2 to 3 in. above the crest of the channel side slopes. ■ Beginning at the downstream end and in the center of the channel, place the initial end of the first roll in the anchor trench and secure with fastening devices at 12 in. intervals. Note: matting will initially be upside down in anchor trench. ■ In the same manner, position adjacent rolls in anchor trench, overlapping the preceding roll a minimum of 3 in. ■ Secure these initial ends of mats with anchors at 12 in. intervals, backfill and compact soil. ■ Unroll center strip of matting upstream. Stop at next check slot or terminal anchor trench. Unroll adjacent mats upstream in similar fashion, maintaining a 3 in. overlap. ' ■ Fold and secure all rolls of matting snugly into all transverse check slots: Lay mat in the bottom of the slot then fold back against itself. Anchor through both layers of mat at 12 in. intervals, then backfill and compact soil. Continue rolling all mat widths upstream to the. next check slot or terminal anchor trench. ■ Alternate method for non-critical installations: Place two rows of anchors on 6 in. centers at 25 to 30 ft. intervals in lieu of excavated check slots. ■ Staple shingled lap spliced ends a minimum of 12 in. apart on 12 in. intervals. ■ Place edges of outside mats in previously excavated longitudinal slots; anchor using prescribed staple pattern, backfill, and compact soil. 1 ■ Anchor, fill, and compact upstream end of mat in a 12 in. by 6 in. terminal trench.

The silt fence detains , sediment -laden water, promoting sedimentation behind the fence. Suitable Applications Silt fences are suitable for perimeter control, placed below areas where sheet flows discharge from the site. They should also be used as interior controls below -disturbed areas where runoff may occur in the form of sheet and rill erosion. Silt fences are generally ineffective in locations where the flow is concentrated and are only applicable for sheet or overland flows. Silt fences are most effective when used in combination with erosion controls.

If not installed at the same elevation throughout, silt fences will create erosion. ' ■ Filter fences will create a temporary sedimentation pond on the upstream side of the fence and may cause temporary flooding. Fences not constructed on a level contour will be ' overtopped by concentrated flow resulting in failure of the filter fence. ■ Improperly installed fences are subject to failure from undercutting, overlapping, or collapsing. ' - Not effective unless trenched and keyed in. - Not intended for use as mid -slope protection on slopes greater than 4:1(H:V). ' - Do not allow water depth to exceed 1.5 ft at any point. Implementation t General A silt fence is a temporary sediment barrier consisting of filter fabric stretched across and attached to supporting posts, entrenched, and, depending upon the strength of fabric used, supported with plastic or wire mesh fence. Silt fences trap sediment by intercepting and detaining small amounts of sediment -laden runoff from disturbed areas in order to promote sedimentation behind the fence. ' Silt fences are preferable to straw bale barriers in many cases. 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. While the failure rate of silt fences is lower than that of straw bale barriers, there are many instances where silt fences have been improperly installed. The following layout and installation guidance can improve performance and should be followed: ' ■ Use principally in areas where sheet flow occurs. ' ■ Don't use in streams, channels, or anywhere flow is concentrated. Don't use silt fences to divert flow. ■ Don't use below slopes subject to creep, slumping, or landslides. ■ Select filter fabric that retains 85% of soil by weight, based on sieve analysis, but that is not finer than an equivalent opening size of 70. ' ■ Install along a level contour, so water does not pond more than 1.5 ft at any point along the silt fence. ■ The maximum length of slope draining to any point along the silt fence should be 200 ft or less. ■ The maximum slope perpendicular to the fence line should be 1:1. 2 of 8 California Stormwater BMP Handbook January 2003 ' Construction www.cabmphandbooks.com 1 Silt Fence SE -1 ' ■ Provide sufficient room for runoff to pond behind the fence and to allow sediment removal equipment to pass between the silt fence and toes of slopes or other obstructions. About 1200 ftz of ponding area should be provided for every acre draining to the fence. ' ■ Turn the ends of the filter fence uphill to prevent stormwater from flowing around the fence. ■ Leave an undisturbed or stabilized area immediately down slope from the fence where feasible. ' ■ Silt fences should remain in place until the disturbed area is permanently stabilized. ' Design and Layout Selection of a filter fabric is based on soil conditions at the construction site (which affect the equivalent opening size (EOS) fabric specification) and characteristics of the support fence (which affect the choice of tensile strength). The designer should specify a filter fabric that retains the soil found on the construction site yet that it has openings large enough to permit drainage and prevent clogging. The following criteria is recommended for selection of the equivalent opening size: 1. If 50 percent or less of the soil, by weight, will pass the U.S. Standard Sieve No. 200, select the EOS to retain 85 % of the soil. The EOS should not be finer than EOS 70. 2. For all other soil types, the EOS-should be no larger than the openings in the U.S. Standard Sieve No. 70 except where direct discharge to a stream, lake, or wetland will occur, then the EOS should be no larger than Standard Sieve No. loo. 1 To reduce the chance of clogging, it is preferable to specify a fabric with openings as large as allowed by the criteria. No fabric should be specified with an EOS smaller than U.S. Standard ' Sieve No. loo. If 85% or more of a soil, by weight, passes through the openings in a No. 200 sieve, filter fabric should not be used. Most of the particles in such a soil would not be retained if the EOS was too large and they would clog the fabric quickly if the EOS were small enough to capture the soil. ' The fence should be supported by a plastic or wire mesh if the fabric selected does not have sufficient strength and bursting strength characteristics for the planned application (as ' recommended by the fabric manufacturer). Filter fabric material should contain ultraviolet inhibitors and stabilizers to provide a minimum of six months of expected usable construction life at a temperature range of o OF to 120 OF. ' ■ Layout in accordance with attached figures. ■ For slopes steeper than 2:1(H:V) and that contain a high number of rocks or large dirt clods ' that tend to dislodge, it may be necessary to install additional protection immediately adjacent to the bottom of the slope, prior to installing silt fence. Additional protection may be a chain link fence or a cable fence. ■ For slopes adjacent to sensitive receiving waters or Environmentally Sensitive Areas (ESAs), silt fence should be used in conjunction with erosion control BMPs. J ' January 2003 California Stormwater BMP Handbook 3 of 8 Construction www.cabmphandbooks.com 1 SE -1 Silt Fence Materials ' ■ Silt fence fabric should be woven polypropylene with a minimum width of 36 in. and a minimum tensile strength of ioo lb force. The fabric should conform to the requirements in ASTM designation D4632 and should have an integral reinforcement layer. The ' reinforcement layer should be a polypropylene, or equivalent, net provided by the manufacturer. The permittivity of the fabric should be between o.1 sec -1 and o.15 sec -1 in conformance with the requirements in ASTM designation D449i. ' ■ Wood stakes should be commercial quality lumber of the size and shape shown on the plans. Each stake should be free from decay, splits or cracks longer than the thickness of the stake or other defects that would weaken the stakes and cause the stakes to be structurally unsuitable. ■ Staples used to fasten the fence fabric to the stakes should be not less than 1.75 in. long and ' should be fabricated from 15 gauge or heavier wire. The wire used to fasten the tops of the stakes together when joining two sections of fence should be 9 gauge or heavier wire. Galvanizing of the fastening wire will not be required. ■ There are new products that may use prefabricated plastic holders for the silt fence and use bar reinforcement instead of wood stakes. If bar reinforcement is used in lieu of wood stakes, use number four or greater bar. Provide end protection for any exposed bar ' reinforcement. Installation Guidelines Silt fences are to be constructed on a level contour. Sufficient area should exist behind the fence ' for ponding to occur without flooding or overtopping the fence. ■ A trench should be excavated approximately 6 in. wide and 6 in. deep along the line,the ' proposed silt fence. ■ Bottom of the silt fence should be keyed -in a minimum of 12 in. ■ Posts should be spaced a maximum of 6 ft apart and driven securely into the ground a minimum of 18 in. or 12 in. below the bottom of the trench. ' ■ When standard strength filter fabric is used, a plastic or wire mesh support fence should be fastened securely to the upslope side of posts using heavy—duty wire staples at least 1 in. long. The mesh should extend into the trench. When extra -strength filter fabric and closer post spacing are used, the mesh support fence may be eliminated. Filter fabric should be purchased in a long roll, then cut to the length of the barrier. When joints are necessary, filter cloth should be spliced together only at a support post, with a minimum 6 in. overlap ' and both ends securely fastened to the post. ■ The trench should be backfilled with compacted native material. ■ Construct silt fences with a setback of at least 3 ft from the toe of a slope. Where a silt fence is determined to be not practicable due to specific site conditions, the silt fence may be constructed at the toe of the slope, but should be constructed as far from the toe of the slope ' as practicable. Silt fences close to the toe of the slope will be less effective and difficult to maintain. 4 of 8 California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com Silt Fence SE -1 ■ Construct the length of each reach so that the change in base elevation along the reach does not exceed 1/3 the height of the barrier; in no case should the reach exceed 50o ft.

'I Inspection and Maintenance ■ Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non -rainy season. ' ■ Repair undercut silt fences. ■ Repair or replace split, torn, slumping, or weathered fabric. The lifespan of silt fence fabric is generally 5 to 8 months. ■ Silt fences that are damaged and become unsuitable for the intended purpose should be removed from the site of work, disposed of, and replaced with new silt fence barriers. 1 ■ Sediment that accumulates in the BMP must be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. Sediment removed during maintenance may be incorporated into earthwork on the site or disposed at an appropriate location. ■ Silt fences should be left in place until the upstream area is permanently stabilized. Until then, the silt fence must be inspected and maintained. ■ Holes, depressions, or other ground disturbance caused by the removal of the silt fences ' should be backfilled and repaired.

When fiber rolls are placed at the toe and on the face of slopes, they intercept runoff, reduce its flow velocity, release the runoff as sheet flow, and provide removal of sediment from the runoff. By interrupting the length of a slope, fiber rolls can also reduce erosion. Suitable Applications Fiber rolls may be suitable: ■ Along the toe, top, face, and at grade breaks of exposed and erodible slopes to shorten slope length and spread runoff as sheet flow ■ At the end of a downward slope where it transitions to a steeper slope ■ Along the perimeter of a project ■ As check dams in unlined ditches ■ Down-slope of exposed soil areas ■ Around temporary stockpiles Limitations ■ Fiber rolls are not effective unless trenched objectives EC Erosion Control ✓ SE Sediment Control ✓ TC Tracking Control WE Wind Erosion Control NS NonStormwater Management Control WM Waste Management and Materials Pollution Control Legend: ✓ Primary Objective ✓ Secondary Objective Targeted Constituents Sediment ✓ Nutrients Trash Metals Bacteria Oil and Grease Organics ------------------- Potential Alternatives SE -1 Sill Fence SE -6 Gravel Bag Berm SE -8 Sandbag Barrier SE -9 Straw Bale Barrier �e rnla Stormwater :,: Quality //i;, January 2003 California Stormwater BMP Handbook 1 of 4 Construction www.cabmphandbooks.com SE -5 Fiber Rolls ■ Fiber rolls at the toe of slopes greater than 5:1(H:V) should be a minimum of 20 in. diameter or installations achieving the same protection (i.e. stacked smaller diameter fiber rolls, etc.). ■ Difficult to move once saturated. ■ If not properly staked and trenched in, fiber rolls could be transported by high flows. ■ Fiber rolls have a very limited sediment capture zone. ■ Fiber rolls should not be used on slopes subject to creep, slumping, or landslide. implementation Fiber Roll Materials ■ Fiber rolls should be either prefabricated rolls or rolled tubes of erosion control blanket.

Costs . Material costs for fiber rolls range from $20 - $30 per 25 ft roll. Inspection and Maintenance ■ Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non -rainy season. ■ Repair or replace split, torn, unraveling, or slumping fiber rolls. ■ If the fiber roll is used as a sediment capture device, or as an erosion control device to maintain sheet flows, sediment that accumulates in the BMP must be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when sediment accumulation reaches one-half the designated sediment storage depth, usually one-half the distance between the top of the fiber roll and the adjacent ground surface. Sediment removed during maintenance may be incorporated into earthwork on the site of disposed at an appropriate location. ■ If fiber rolls are used for erosion control, such as in,a mini check dam, sediment removal should not be required as long as the system continues to control the grade. Sediment control BMPs will likely be required in conjunction with this type of application.

' ■ Gravel bag berm may not be appropriate for drainage areas greater than 5 acres. ■ Runoff will pond upstream of the filter, possibly causing flooding if sufficient space'does not ' exist. ■ Degraded gravel bags may rupture when removed, spilling contents. ' ■ Installation can be labor intensive. ■ Berms may have limited durability for long-term projects. ' ■ When used to detain concentrated flows, maintenance requirements increase. Implementation General A gravel bag berm consists of a row of open graded gravel—filled bags placed on a level contour. When appropriately placed, a gravel bag berm intercepts and slows sheet flow runoff, causing temporary ponding. The temporary ponding provides quiescent conditions allowing sediment to settle. The open graded gravel in the bags is porous, which allows the ponded runoff to flow slowly through the bags, releasing the runoff as sheet flows. Gravel bag berms also interrupt the slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets, which erode rills, and ultimately gullies, into disturbed, sloped soils. Gravel bag berms are similar to sand bag barriers, but are more porous. Design and Layout ■ Locate gravel bag berms on level contours. - Slopes between 20:1 and 2:1 (H:V): Gravel bags should be placed at a maximum interval of 50 ft (a closer spacing is more effective), with the first row near the slope toe.

Implementation - General A sandbag barrier consists of a row of sand -filled bags placed on a level contour. When appropriately placed, a sandbag barrier intercepts and slows sheet flow runoff, causing temporary ponding. The temporary ponding provides quiescent conditions allowing sediment to settle. While the sand -filled bags are porous, the fine sand tends to quickly plug with sediment, limiting the rate of flow through the barrier. If a porous barrier is desired, consider SE -i, Silt Fence, SE -5, Fiber Rolls, SE -6, Gravel Bag Berms, or SE -9, Straw Bale Barriers. Sandbag barriers also interrupt the slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets which erode rills, and ultimately gullies, into disturbed, sloped soils. Sandbag barriers are similar to ground bag berms, but less porous. Design and Layout ' ■ Locate sandbag barriers on a level contour. - Slopes between 20:1 and 2:1 (H:V): Sandbags should be placed at a maximum interval of 50 ft (a closer spacing is more effective), with the first row near the slope toe. - Slopes 2:1 (H:V) or steeper: Sandbags should be placed at a maximum interval of 25 ft (a closer spacing is more effective), with the first row placed near the slope toe. ■ Turn the ends of the sandbag, barrier up slope to prevent runoff from going around the barrier. ■ Allow sufficient space up slope from the barrier to allow ponding, and to provide room for sediment storage. ■ For installation near the toe of the slope, consider moving the barrier away from the slope toe to facilitate cleaning.

Barrier Description and Purpose A straw bale barrier is a series of straw bales placed on a level contour to intercept sheet flows. Straw bale barriers pond sheet- flow runoff, allowing sediment to settle out. Suitable Applications Straw bale barriers may be suitable: ■ As a linear sediment control measure: Below the toe of slopes and erodible slopes As sediment traps at culvert/pipe outlets Below other small cleared areas - Along the perimeter of a site - Down slope of exposed soil areas - Around temporary stockpiles and spoil areas - Parallel to a roadway to keep sediment off paved areas - Along streams and channels ■ As linear erosion control measure: SE -9 .Objectives EC Erosion Control SE Sediment Control ✓ TC Tracking Control WE Wind Erosion Control NS Non-Stormwater Management Control WM Waste Management and Materials Pollution Control Legend: ✓ Primary objective •' Secondary Objective Targeted Constituents Sediment ✓ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives SE -1 Silt Fence SE -5 Fiber Rolls SE -6 Gravel Bag Berm SE -8 Sandbag Barrier - Along the face and at grade breaks of exposed and erodibleV�> -S 0 A slopes to shorten slope length and spread runoff as sheet nia flow mwater uality Association January 2003 California Stormwater BMP Handbook 1 of 6 Construction www.cabmphandbooks.com U I 11 SE -9 Straw Bale Barrier - At the top of slopes to divert runoff away from disturbed slopes - As check dams across mildly sloped construction roads Limitations Straw bale barriers: ■ Are not to be used for extended periods of time because they tend to rot and fall apart ■ Are suitable only for sheet flow on slopes of io % or flatter ■ Are not appropriate for large drainage areas, limit to one acre or less ■ May require constant maintenance due to rotting ■ Are not recommended for concentrated flow, inlet protection, channel flow, and live streams ■ Cannot be made of bale bindings of jute or cotton ■ Require labor-intensive installation and maintenance ■ Cannot be used on paved surfaces ■ Should not to be used for drain inlet protection ■ Should not be used on lined ditches ■ May introduce undesirable non-native plants to the area Implementation General A straw bale barrier consists of a row of straw bales placed on a level contour. When appropriately placed, a straw bale barrier intercepts and slows sheet flow runoff, causing temporary ponding. The temporary ponding provides quiescent conditions allowing sediment to settle. Straw bale barriers also interrupt the slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets, which erode rills, and ultimately gullies, into disturbed, sloped soils. Straw bale barriers have not been as effective as expected due to improper use. These barriers have been placed in streams and drainage ways where runoff volumes and velocities have caused the barriers to wash out. In addition, failure to stake and entrench the straw bale has allowed undercutting and end flow. Use of straw bale barriers in accordance with this BMP should produce acceptable results. Design and Layout ■ Locate straw bale barriers on a level contour. - Slopes up to loa (H:V): Straw bales should be placed at a maximum interval of 50 ft (a closer spacing is more effective), with the first row near the toe of slope. - Slopes greater than lo: 1(H:V): Not recommended. 2 of 6 Callfornla Stormwater BMP Handbook January 2003 Constructlon www.cabmphandbooks.com Straw Bale Barrier SE -9 4 ■ Turn the ends of the straw bale barrier up slope to prevent runoff from going around the ' barrier. ■ Allow sufficient space up slope from the barrier to allow ponding, and to provide room for sediment storage. ■ For installation near the toe of the slope, consider moving the barrier away from the slope i toe to facilitate cleaning. To prevent flow behind the barrier, sand bags can be placed perpendicular to the barrier to serve as cross barriers. ■ Drainage area should not exceed 1 acre, or 0.25 acre per loo ft of barrier. ' ■ Maximum flow path to the barrier should be limited to loo ft. ■ Straw bale barriers should consist of two parallel rows. Butt ends of bales tightly ' - Stagger butt joints between front and back row ' - Each row of bales must be trenched in and firmly staked a• ' ■ Straw bale barriers are limited in height to one bale laid on its side. c■ Anchor bales with either two wood stakes or four bars driven through the bale and into the j soil. Drive the first stake towards the butt joint with the adjacent bale to force the bales together. ■ See attached figure for installation details. i Materials ■ Straw Bale Size: Each straw bale should be a minimum of 14 in. wide, 18 in. in height, 36 in. in length and should have a minimum mass of 50 lbs. The straw bale should be composed entirely of vegetative matter, except for the binding material. ■ Bale Bindings: Bales should be bound by steel wire, nylon or polypropylene string placed i horizontally. Jute and cotton binding should not be used. Baling wire should be a minimum diameter of 14 gauge. Nylon or polypropylene string should be approximately 12 gauge in ' diameter with a breaking strength of 80 lbs force. ■ Stakes: Wood stakes should be commercial quality lumber of the size and shape shown on the plans. Each stake should be free from decay, splits or cracks longer than the thickness of the stake, or other defects that would weaken the stakes and cause the stakes to be structurally unsuitable. Steel bar reinforcement should be equal to a #4 designation or greater. End protection should be provided for any exposed bar reinforcement. '# Costs Straw bales cost $5 - $y each. Adequate labor should be budgeted for installation and maintenance.

California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com, i Storm Drain Inlet Protection SE -10 Description and Purpose Storm drain inlet protection consists of a sediment filter or an impounding area around or upstream of a storm drain, drop inlet, or curb inlet. Storm drain inlet protection measures temporarily pond runoff before it enters the storm drain, allowing sediment to settle. Some filter configurations also remove sediment by filtering, but usually the ponding action results in the greatest sediment reduction. Suitable Applications Every storm drain inlet receiving sediment -laden runoff should be protected. Limitations ■ Drainage area should not exceed 1 acre. ■ Straw bales, while potentially effective, have not produced in practice satisfactory results, primarily due to improper installation. , ■ Requires an adequate area for water to pond without encroaching into portions of the roadway subject to traffic. ■ Inlet protection usually requires other methods of temporary protection to prevent sediment -laden stormwater and non-stormwater discharges from entering the storm drain system. ■ Sediment removal may be difficult in high flow conditions or if runoff is heavily sediment laden.

' ■ For drainage areas larger than 1 acre, runoff should be routed to a sediment -trapping device designed for larger flows. See BMPs SE -2, Sediment Basin, and SE -3, Sediment Traps. . ' ■ Excavated drop inlet sediment traps are appropriate where relatively heavy flows are expected, and overflow capability is needed. ' Implementation General Large amounts of sediment may enter the storm drain system when storm drains are installed ' before the upslope drainage area is stabilized, or where construction is adjacent to an existing storm drain. In cases of extreme sediment loading, the storm drain 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. ' Inlet control measures presented in this handbook should not be used for inlets draining more than one acre. Runoff from larger disturbed areas should be first routed through SE -2, ' Sediment Basin or SE -3, Sediment Trap. Different types of inlet protection are appropriate for different applications depending on site conditions and the type of inlet. Inlet protection methods not presented in this handbook should be approved by the local stormwater ~� management agency. ,1 Design and Layout Identify existing and planned storm drain inlets that have the potential to receive sediment - laden surface runoff. Determine if storm drain inlet protection is needed and which method to use. ' ■ Limit upstream drainage area to i acre maximum. For larger drainage areas, use SE -2, Sediment Basin, or SE -3, Sediment Trap, upstream of the inlet protection device. ' ■ The key to successful and safe use of storm drain inlet protection devices is to know where runoff will pond or be diverted. - Determine the acceptable location and extent of ponding in the vicinity of the drain inlet. ' The acceptable location and extent of ponding will influence the type and design of the storm drain inlet protection device. - Determine the extent of potential runoff diversion caused by the storm drain inlet ' protection device. Runoff ponded by inlet protection devices may flow around the device and towards the next downstream inlet. In some cases, this is acceptable; in other cases, serious erosion or downstream property damage can be caused by these diversions. The ' possibility of runoff diversions will influence whether or not storm drain inlet protection is suitable; and, if suitable, the type and design of the device. ■ The location and extent of ponding, and the extent of diversion, can usually be controlled ' - through appropriate placement of the inlet protection device. In some cases, moving the ' 2 of 9 California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com Storm Drain Inlet Protection, SE -.10 inlet protection device a short distance upstream of the actual inlet can provide more efficient sediment control, limit ponding to desired areas, and prevent or control diversions. ■ Four types of inlet protection are presented below. However, it is recognized that other effective methods and proprietary devices exist and may be selected. - Filter Fabric Fence: Appropriate for drainage basins with less than a 5% slope, sheet flows, and flows under o.5 cfs. - Excavated Drop Inlet Sediment Trap: An excavated area around the inlet to trap sediment (SE -3). - Gravel bag barrier: Used to create a small sediment trap upstream of inlets on sloped, paved streets. Appropriate for sheet flow or when concentrated flow may exceed 0.5 cfs, and where overtopping is required to prevent flooding. - Block and Gravel Filter: Appropriate for flows greater than 0.5 cfs. ■ Select the appropriate type of inlet protection and design as referred to or as described in this fact sheet. ■ Provide area around the inlet for water to pond without flooding structures and property. ■ Grates and spaces around all inlets should be sealed to prevent seepage of sediment -laden water. ■ Excavate sediment sumps (where needed)1 to 2 ft with 2:1 side slopes around the inlet. Installation ■ DI Protection Type s -Filter Fabric Fence -The filter fabric fence (Type 1) protection is shown in the attached figure. Similar to constructing a silt fence; see BMP SE -i, Silt Fence. Do not place filter fabric underneath the inlet grate since the collected sediment may fall into the drain inlet when the fabric is removed or replaced. t i. • Excavate a trench approximately 6 in. wide and 6 in. deep along the line of the silt fence inlet protection.device. 2. Place 2 in. by 2 in. wooden stakes around the perimeter of the inlet a maximum of 3 ft apart and drive them at least 18 in. into the ground or 12 in. below the bottom of the trench. The stakes must be at least 48 in. 3. Lay fabric along bottom of trench, up side of trench, and then up stakes. See SE -i, Silt Fence, for details. The maximum silt fence height around the inlet is 24 in. 4. Staple the filter fabric (for materials and specifications, see SE -i, Silt Fence) to wooden stakes. Use heavy-duty wire staples at least 1 in. in length. 5. Backfill the trench with gravel or compacted earth all the Nay around. ■ DI Protection 7)1pe 2 -Excavated Drop Inlet Sediment Trap -The excavated drop inlet sediment trap (Type 2) is shown in the attached figures.

Size excavated trap to provide a minimum storage capacity calculated at the rate 67 yd3/acre of drainage area. ■ DI Protection T)jpe 3 - Gravel bag - The gravel bag barrier Crype 3) is shown in the figures. Flow from a severe storm should not overtop the curb. In areas of high clay and silts, use filter fabric and gravel as additional filter media. Construct gravel bags in accordance with SE -6, Gravel Bag Berm. Gravel bags should be used due to their high permeability. 1. Use sand bag made of geotextile fabric (not burlap) and fill with o.75 in. rock or 0.25 in. pea gravel. 2. Construct on gently sloping street. 3. Leave room upstream of barrier for water to pond and sediment to settle. 4. Place several layers of sand bags — overlapping the bags and packing them tightly together. 5. Leave gap of one bag on the top row to serve as a spillway. Flow from a severe storm , (e.g., io year storm) should not overtop the curb. ■ DI Protection Type 4 —Block and Gravel Filter -The block and gravel filter (Type 4) is shown in the figures. Block and gravel filters are suitable for curb inlets commonly used in residential, commercial, and industrial construction. 1. Place hardware cloth or comparable wire mesh with o.5 in. openings over the drop inlet so that the wire extends a minimum of 1 ft beyond each side of the inlet structure. If more than one strip is necessary, overlap the strips. Place filter fabric over the wire mesh. 2. 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 in., 8 in., and 12 in. wide. The row of blocks should be at least 12 in. but no greater than 24 in. high. 3. 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 o.5 in. opening. 4. Pile washed stone against the wire mesh to the top of the blocks. Use 0.75 to 3 in. Costs ■ Average annual cost for installation and maintenance (one year useful life) is $200 per inlet. Inspection and Maintenance ■ Inspect BMPs prior to forecast rain, daily during extended rain events, after rain events, weekly during the rainy season, and at two-week intervals during the non -rainy season. 4 of 9 California. Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com ki Storm Drain Inlet Protection 5E-10 ■ Filter Fabric Fences. If the fabric becomes clogged, torn, or degrades, it should be replaced. Make sure the stakes are securely driven in the ground and are in good shape (i.e., not bent, cracked, or splintered, and are reasonably perpendicular to the ground). Replace damaged stakes. ■ Gravel Filters. If the gravel becomes clogged with sediment, it must be carefully removed from the inlet and either cleaned or replaced. Since cleaning gravel at a construction site may be difficult, consider using the sediment -laden stone as fill material and put fresh stone around the inlet. Inspect bags for.holes, gashes, and snags, and replace bags as needed. Check gravel bags for proper arrangement and displacement. ■ Sediment that accumulates in the BMP must be periodically removed in order to maintain BMP effectiveness. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height. Sediment removed during maintenance may be incorporated into earthwork on the site ore disposed at an appropriate location. ■ Remove storm drain inlet protection once the drainage area is stabilized. I - Clean and regrade area around the inlet and clean the inside of the storm drain inlet as it must be free of 'sediment and debris at the time of final inspection.

Suitable Applications Use at construction sites: ■ Where dirt or mud can be tracked onto public roads. ■ Adjacent to water bodies. ■ Where poor soils are encountered. ■ Where dust is a problem during dry weather conditions. Limitations ■ Entrances and exits require periodic top dressing with additional stones. ■ This BMP should be used in conjunction with street sweeping on adjacent public right of way.

The purpose of a stabilized construction entrance is to reduce or eliminate the tracking of sediment onto public rights of way or streets. Reducing tracking of sediments and other pollutants onto paved roads helps prevent deposition'of sediments into local storm drains and production of airborne dust. Where traffic will be entering or leaving the construction site, a stabilized construction entrance should be used. NPDES permits require that appropriate measures be implemented to prevent tracking of sediments onto paved roadways, where a significant source of sediments is derived from mud and dirt carried out from unpaved roads and construction sites. Stabilized construction entrances are moderately effective in removing sediment from equipment leaving a construction site. The entrance should be built on level ground. Advantages of the Stabilized Construction Entrance/Exit is that it does remove some sediment from equipment and serves to channel construction traffic in and out of the site at specified locations. Efficiency is greatly increased when a washing rack is included as part of a stabilized construction entrance/exit. Design and Layout ■ Construct on level ground where possible. ■ Select 3 to 6 in. diameter stones. ■ Use minimum depth of stones of 12 in. oras recommended by soils engineer. ■ Construct length of 50 ft minimum, and 30 ft minimum width. ■ Rumble racks constructed of steel panels with ridges and installed in the stabilized entrance/exit will help remove additional sediment and to keep adjacent streets clean. ■ Provide ample turning radii as part of the entrance. ■ Limit the points of entrance/exit to the construction site. ■ Limit speed of vehicles to control dust. ■ Properly grade each construction entrance/exit to prevent runoff from leaving the construction site. ■ Route runoff from stabilized entrances/exits through a sediment trapping device before discharge. ■ Design stabilized entrance/exit to support heaviest vehicles and equipment that will use it. ■ Select construction access stabilization (aggregate, asphaltic concrete, concrete) based on longevity, required performance, and site conditions. Do not use asphalt concrete (AC) grindings for stabilized construction access/roadway. 2 of 6 California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com 1 Costs Average annual cost for installation and maintenance may vary from $1,200 to $4,80o each, averaging $2,400 per entrance.

Suitable Applications This BMP should be applied for the following conditions: ■ Temporary Construction Traffic: - Phased construction projects and offsite road access Objectives EC Erosion Control ✓ SE Sediment Control ✓ TC Tracking Control ✓ WE Wind Erosion Control NS Non-Stormwater Management Control WM Waste Management and Materials Pollution Control - Legend: if Primary Objective ./ Secondary Objective Targeted Constituents Sediment ✓ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives None ' - Construction during wet weather ■ Construction roadways and detour roads: ' Where mud tracldng is a problem during wet weather - Where dust is a problem during dry weather - Adjacent to water bodies - Where poor soils are encountered Limitations ■ The roadway must be removed or paved when construction is complete. XAS Q A .'California Stormwater ' ouallty Association January 2003 California Stormwater BMP Handbook 1 of 4 ' Construction www.cabmphandbooks.com q I ' L TC -2 Stabilized Construction Roadway ■ Certain chemical stabilization methods may cause stormwater or soil pollution and should not be used. See WE -i, Wind Erosion Control. ■ Management of construction traffic is subject to air quality control measures. Contact the ' local air quality management agency. ■ Materials will likely need to be removed prior to final project grading and stabilization. ' ■ Use of this BMP may not be applicable to very short duration projects. Implementation ' General Areas that are graded for construction vehicle transport and parking purposes are especially susceptible to erosion and dust. The exposed soil surface is continually disturbed, leaving no ' opportunity for vegetative stabilization. Such areas also tend to collect and transport runoff waters along their surfaces. During wet weather, they often become muddy quagmires that generate significant quantities of sediment that may pollute nearby streams or be transported offsite on the wheels of construction vehicles. Dirt roads can become so unstable during wet ' weather that they are virtually unusable. Efficient construction road stabilization not only reduces onsite erosion but also can ' significantly speed onsite work, avoid instances of immobilized machinery and delivery vehicles, and generally improve site efficiency and working conditions during adverse weather Installation/Application Criteria Permanent roads and parking areas should be paved as soon as possible after grading. As an alternative where construction will be phased, the early application of gravel or chemical stabilization may solve potential erosion and stability problems. Temporary gravel roadway ' should be considered during the rainy season and on slopes greater than 5%. Temporary roads should follow the contour of the natural terrain to the maximum extent ' possible. Slope should not exceed 15%. Roadways should be carefully graded to drain transversely. Provide drainage swales on each side of the roadway, in the case of a crowned section or one side in the case of a super elevated section. Simple gravel berms without a trench can also be used. ' Installed inlets should be protected to prevent sediment laden water from entering the storm sewer system (SE -1o, Storm Drain Inlet Protection). In addition, the following criteria should ' be considered. ■ Road should follow topographic contours to reduce erosion of the roadway. ' ■ The roadway slope should not exceed 15%. 1 ■ Chemical stabilizers or water are usually required on gravel or dirt roads to prevent dust ' (WE -i, Wind Erosion Control). ■ Properly grade roadway to prevent runoff from leaving the construction site. ■ Design stabilized access to support heaviest vehicles and equipment that will use it. ._i ' 2 of 4 California Stormwater BMP Handbook January 2003 Construction www.cabmphandbooks.com 1 Stabilized Construction, Roadway TC -2 ■ Stabilize roadway using aggregate, asphalt concrete, or concrete based on longevity, required performance, and site conditions. The use of cold mix asphalt or asphalt concrete (AC) grindings for stabilized construction roadway is not allowed. ' ■ Coordinate materials with those used for stabilized construction entrance/exit points. ■ If aggregate is selected, place crushed aggregate over geotextile fabric to at least 12 in. depth. A crushed aggregate greater than 3 in. but smaller than 6 in. should be used. Inspection and Maintenance ■ Inspect and verify that activity—based BMPs are in place prior to the commencement of ' associated activities. While activities associated with the BMP are under way, impact weekly during the rainy season and of two-week intervals in the non -rainy season to verify continued BMP implementation. ' ■ Keep all temporary roadway ditches clear. . ■ When no longer required, remove`stabilized construction roadway and re -grade and repair slopes. ■ Periodically apply additional aggregate on gravel roads. ■ Active dirt construction roads are commonly watered three or more times per day during the dry season. Costs ' Gravel construction roads are moderately expensive, but cost is often balanced by reductions in construction delay. No additional costs for dust control on construction roads should be ' required above that needed to meet local aii quality requirements. { References Blueprint for a Clean Bay: Best Management Practices to Prevent Stormwater Pollution from ' Construction Related Activities; Santa Clara Valley Nonpoint Source Pollution Control Program, 1995• Coastal Nonpoint Pollution Control Program; Program Development and Approval Guidance, Working Group, Working Paper; USEPA, April 1992• Manual of Standards of Erosion and Sediment Control Measures, Association of Bay Area Governments, May 1995• Stormwater Quality Handbooks Construction Site Best Management Practices (BMPs) Manual, State of California Department of Transportation (Caltrans), November 2000.

Suitable Applications Tire washes may be used on construction sites where dirt and mud tracking onto public roads by construction vehicles may occur. Limitations ■ The tire wash requires a supply of wash water. ■ A turnout or doublewide exit is required to avoid having entering vehicles drive through the wash area. ■ Do not use where wet tire trucks leaving the site leave the road dangerously slick. Implementation ■ Incorporate with a stabilized construction entrance/exit. See TC -1, Stabilized Construction Entrance/Exit. ■ Construct on level ground when possible, on a pad of coarse aggregate greater than 3 in. but smaller than 6 in. A Legend: ✓ Primary Objective ./ Secondary Objective Targeted Constituents Sediment ✓ Nutrients Trash Metals Bacteria Oil and Grease Organics Potential Alternatives TC -1 Stabilized Construction Entrance/Exit geotextile fabric should be placed below the aggregate. ° . :S ■ Wash rack should be designed and constructed/manufactured California ater for anticipated traffic loads. Storm 'Quality P ouaiity Association January 2003 California Stormwater BMP Handbook 1 of 3 Construction www.cabmphandbooks.com TC -3 Entrance/Outlet Tire Wash . ■ Provide a drainage ditch that will convey the runoff from the wash area to a sediment trapping device. The drainage ditch should be of sufficient grade, width, and depth to carry the wash runoff. ■ Use hoses with automatic shutoff nozzles to prevent hoses from being left on. ■ Require that all employees, subcontractors, and others that leave the site with mud caked tires and undercarriages to use the wash facility. ■ Implement SC -7, Street Sweeping and Vacuuming, as needed. Costs Costs are low for installation of wash rack. Inspection and Maintenance ■ Inspect and verify that activity—based BMPs are in place prior to the commencement of associated activities. While activities associated with the BMP are under way, inspect weekly during the rainy season and of two-week intervals in the non -rainy season to verify continued BMP implementation. ■ Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges occur. ■ Remove accumulated sediment in wash rack and/or sediment trap to maintain system performance. ■ Inspect routinely for damage and repair as needed.
