Maintenance Inspections Maintenance of ED ponds is driven by annual inspections that evaluate the condition and performance of the pond, including the following: • Measure sediment accumulation levels in forebay. • Monitor the growth of wetlands, trees and shrubs planted. Record the species and their approximate coverage, and note the presence of any invasive plant species. • Inspect the condition of stormwater inlets to the pond for material damage, erosion or undercutting. • Inspect the banks of upstream and downstream channels for evidence of sloughing, animal burrows, boggy areas, woody growth, or gully erosion that may undermine embankment integrity. • Inspect pond outfall channel for erosion, undercutting, rip -rap displacement, woody growth, etc. • Inspect condition of principal spillway and riser for evidence of spalling, joint failure, leakage, corrosion, etc. • Inspect condition of all trash racks, reverse sloped pipes or flashboard risers for evidence of clogging, leakage, debris accumulation, etc. • Inspect maintenance access to ensure it is free of woody vegetation, and check to see whether valves, manholes and locks can be opened and operated. • Inspect internal and external side slopes of the pond for evidence of sparse vegetative cover, erosion, or slumping, and make needed repairs immediately. Based on inspection results, specific maintenance tasks will be triggered. Example maintenance inspection checklists for ED Ponds can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Handbook (2010). 8.1. Construction Sequence The following is a typical construction sequence to properly install a dry ED pond. The steps may be modified to reflect different dry ED pond designs, site conditions, and the size, complexity and configuration of the proposed facility. Step 1: Use of'ED pond as an E&S Control. An ED pond may serve as a sediment basin during project construction. If this is done, the volume should be based on the more stringent sizing rule (erosion and sediment control requirement vs. water quality treatment requirement). Installation of the permanent riser should be initiated during the construction phase, and design elevations should be set with final cleanout of the sediment basin and conversion to the post -construction ED pond in mind. The bottom elevation of the ED pond should be lower than the bottom elevation of the temporary sediment basin. The construction notes should clearly indicate that the facility will be dewatered, dredged and re- graded to design dimensions after the original site construction is complete. Appropriate procedures should be implemented to prevent discharge of turbid waters when the basin is being converted into an ED pond. Step 2. Stabilize the Drainage Area. Final grading and construction of ED pond components should only be constructed after the contributing drainage area to the pond is stabilized. Step 3: Assemble Construction Materials on -site, make sure they meet design specifications, and prepare any staging areas. Step S: Install E&S Controls prior to construction, including temporary de -watering devices and stormwater diversion practices. All areas surrounding the pond that are graded or denuded during construction must be planted with turf grass, native plantings, or other approved methods of soil stabilization. Step 4: Clear and Strip the project area to the desired sub -grade. Step 6: Excavate the Core Trench and Install the Spillway Pipe. Step 7. Install the Riser or Outflow Structure and ensure the top invert of the overflow weir is constructed level at the design elevation. Step 8: Construct the Embankment and any Internal Berms in 8 to 12-inch lifts, or as directed by geotechnical recommendations, and compact as required with appropriate equipment. Step 9: Excavate/Grade until the appropriate elevation and desired contours are achieved for the bottom and side slopes of the ED pond. Step 10: Construct the Emergency Spillway in cut or structurally stabilized soils. Step 11: Install Outlet Protection, including emergency and primary outlet apron protection. Step 12: Stabilize Exposed Soils with temporary seed mixtures appropriate for the pond buffer. All areas above the normal pool elevation should be permanently stabilized by hydroseeding or seeding over straw. Step 13: Plant the Pond Buffer Area, following the pondscaping plan (see Section 6.7). 20. EXTENDED DETENTION BASIN: 9.1. Maintenance Agreements The Virginia Stormwater Management regulations (4 VAC 50-60) specify the circumstances under which a maintenance agreement must be executed between the owner and the VSMP authority, and sets forth inspection requirements, compliance procedures if maintenance is neglected, notification of the local program upon transfer of ownership, and right -of -entry for local program personnel. • Restrictive covenants or other mechanism enforceable by the VSMP authority must be in place to help ensure that ED ponds are maintained, as well as to pass the knowledge along to any subsequent property owners. • Access to ED ponds should be covered by a drainage easement to allow access by the VSMP authority to conduct inspections and perform maintenance when necessary. • All ED ponds must include a long term maintenance agreements consistent with the provisions of the VSMP regulations, and must include the recommended maintenance tasks and a copy of an annual inspection checklist. • The maintenance agreement should also include contact information for owners to get local or state assistance to solve common nuisance problems, such as mosquito control, geese, invasive plants, vegetative management and beaver removal.

THE GOAL OF ESTABLISHING CONSERVED OPEN SPACE IS TO PROTECT A VEGETATED AREA CONTIGUOUS TO A RECEIVING SYSTEM, SUCH AS A STREAM OR NATURAL CHANNEL, FOR TREATING STORMWATER RUNOFF. ESTABLISHING ISOLATED CONSERVED OPEN SPACE POCKETS ON A DEVELOPMENT SITE MAY NOT ACHIEVE THIS GOAL UNLESS THEY EFFECTIVELY SERVE TO CONNECT THE SURFACE RUNOFF TO THE RECEIVING SYSTEM. THEREFORE, A LOCALITY MAY CHOOSE TO ESTABLISH GOALS FOR MINIMUM ACREAGE TO BE CONSERVED (IN TERMS OF TOTAL ACREAGE OR PERCENTAGE OF THE TOTAL PROJECT SITE), AND THE PHYSICAL LOCATION (ADJACENT TO A STREAM, OR OTHER CRITERIA) IN ORDER FOR THE CUMULATIVE CONSERVED OPEN SPACE TO QUALIFY FOR THE RUNOFF REDUCTION CREDIT. • NO MAJOR DISTURBANCE SHALL OCCUR WITHIN THE CONSERVED OPEN SPACE DURING OR AFTER CONSTRUCTION (I.E., NO CLEARING OR GRADING IS ALLOWED EXCEPT TEMPORARY DISTURBANCES ASSOCIATED WITH INCIDENTAL UTILITY CONSTRUCTION, RESTORATION OPERATIONS, OR MANAGEMENT OF NUISANCE VEGETATION). THE CONSERVED OPEN SPACE AREA SHALL NOT BE STRIPPED OF TOPSOIL. SOME LIGHT GRADING MAY BE NEEDED AT THE BOUNDARY TO ESTABLISH A LEVEL ENTRY INTO THE CONSERVED OPEN SPACE. THIS SHALL BE ACCOMPLISHED USING TRACKED VEHICLES TO PREVENT COMPACTION. • THE LIMITS OF DISTURBANCE SHALL BE CLEARLY SHOWN ON ALL CONSTRUCTION DRAWINGS AND PROTECTED BY ACCEPTABLE SIGNAGE AND EROSION CONTROL MEASURES. • A LONG TERM VEGETATION MANAGEMENT PLAN MUST BE PREPARED TO MAINTAIN THE CONSERVED OPEN SPACE IN A NATURAL VEGETATIVE CONDITION. GENERALLY, CONSERVED OPEN SPACE MANAGEMENT PLANS DO NOT ENCOURAGE OR EVEN ALLOW ANY ACTIVE MANAGEMENT. HOWEVER, A SPECIFIC PLAN SHOULD BE DEVELOPED TO MANAGE THE UNINTENDED CONSEQUENCES OF PASSIVE RECREATION, CONTROL INVASIVE SPECIES, PROVIDE FOR TREE AND UNDERSTORY MAINTENANCE, ETC. MANAGED TURF IS NOT CONSIDERED AN ACCEPTABLE FORM OF VEGETATIVE MANAGEMENT, AND ONLY THE PASSIVE RECREATION AREAS OF DEDICATED PARKLAND ARE ELIGIBLE FOR THE PRACTICE (E.G., THE ACTIVELY USED PORTIONS OF BALL FIELDS AND GOLF COURSES ARE NOT ELIGIBLE), ALTHOUGH CONSERVATION AREAS CAN BE IDEAL TREATMENT PRACTICES AT THE EDGES OF TURF -INTENSIVE LAND USES. • THE CONSERVED OPEN SPACE MUST BE PROTECTED BY A PERPETUAL EASEMENT OR DEED RESTRICTION THAT ASSIGNS THE RESPONSIBLE PARTY TO ENSURE THAT NO FUTURE EVELOPMENT, DISTURBANCE, OR CLEARING MAY OCCUR WITHIN THE AREA. • THE PRACTICE DOES NOT APPLY TO JURISDICTIONAL WETLANDS THAT ARE SENSITIVE TO INCREASED INPUTS OF STORMWATER RUNOFF (E.G., BOGS AND FENS). CONSTRUCTION SEQUENCE FOR CONSERVED OPEN SPACE AREAS THE CONSERVED OPEN SPACE MUST BE FULLY PROTECTED DURING THE CONSTRUCTION STAGE OF DEVELOPMENT AND KEPT OUTSIDE THE LIMITS OF DISTURBANCE ON THE EROSION AND SEDIMENT (E&S) CONTROL PLAN. • NO CLEARING, GRADING OR HEAVY EQUIPMENT ACCESS IS ALLOWED EXCEPT TEMPORARY DISTURBANCES ASSOCIATED WITH INCIDENTAL UTILITY CONSTRUCTION, RESTORATION OPERATIONS OR MANAGEMENT OF NUISANCE VEGETATION. THE PERIMETER OF THE CONSERVED OPEN SPACE SHALL BE PROTECTED FROM CONSTRUCTION SEDIMENT BY SUPER SILT FENCE, SINCE THE AREA IS DOWN GRADIENT FROM AREAS OF CONSTRUCTION. • THE LIMITS OF DISTURBANCE SHOULD BE CLEARLY SHOWN ON ALL CONSTRUCTION DRAWINGS AND IDENTIFIED AND PROTECTED IN THE FIELD BY ACCEPTABLE SIGNAGE, AND CHAIN LINK FENCE, ORANGE SAFETY FENCE, SNOW FENCE OR OTHER PROTECTIVE BARRIER TO KEEP UNNECESSARY CONSTRUCTION ACTIVITY OUT OF THE AREA.

BASIN ID REFERS TO THE STORMWATER BASINS DEPICTED ON THE SW-200 AND SW-300 SERIES SHEETS. EXTENDED DETENTION BASIN DESIGN ENERGY BALANCES SCALE: NTS The Energy Balance is based upon the 1-yr return period storm insteadof the 2-yr storm previously required for natural channels in Minimum Standard 19 (and still required for manmade channels). The Energy Balance equation used to calculate the allowable peak rate of runoff was summarized in the Design Criteria section: QPre-Developed X RVPre-Developed QDeveloped = I.F. X RVDeveloped Where: I.F. (Improvement Factor) = 0.8 for sites > 1 acre LDA or 0.9 for sites s 1 acre LDA QDevelHped = the allowable peak flow rate of runoff from the developed site for the 1-yr 24- hour storm. RVDeveloped = the volume of runoff from the site in the developed condition for the 1-yr 24- hour storm. QPre-Develkped = the peak flow rate of runoff from the site in the pre -developed condition for the 1-yr 24-hour storm. RVpre-Developed = the volume of runoff from the site in pre -developed condition for the 1-yr 24-hour storm. DAMN RAY GALLON Lic.

Weeping bvegrass maybe added to any slope or low. maintenance mix during warmer Beetling pencils; add 10-20 Ibslacre in mixes. Note: For all areas apply mulch (straw) at a rate of 1,5 to 2 tons per acre (minimum 2 tons per acre from November through February) Construction Specifications The area of the entrance must be excavated a minimum of 3 inches and must be cleared of all vegetation, roots, and other objectionable material. The filter fabric underliner will then oe placed the full width and length of the entrance. Following the installation of the filter cloth, the stone shall be placed to the specified dimensions. If wash racks are used, they should be installed according to manufacturer's specifications. Any drainage facilities required because of washing should he constructed according to specifications. Conveyance of surface water under entrance, through culverts, ;hall be provided as required. If such conveyance is impossible, the construction of a 'mountable" berm with 5:1 slopes will be permitted. The filter cloth utilized shall be a woven or nonwoven fabric consisting only of continuous chain polymeric filaments or yarns of polyester. The fabric shall be inert to commonly encountered chemicals and hydrocarbons, be mildew and rot resistant, and conform to the nhvsical mor ies noted in Table I.M.A. Seedbed Preparation The soil on a disturbed site must be modified to provide an optimum environment for seed germination and seedling growth. The surface soil must be loose enough for water infiltration and root penetration. The pH (acidity and alkalinity) of the soil must be such that it is not toxic and nutrients are available, usually between pH &0-7.0. Sufficient nutrients (added as fertilizer) must be present. After seed is in place, it must be protected with a mulch to hold moistuC-and modify tempUatllre extremes, and to prevent erosion while 4eedlin are oeT wing. The addition of lime is equally as important as applying fertilizer. Lime is best known as a pH, or acidity, modifier, but it also supplies calcium and magnesium which are plant nutrients. Its effect on pH makes other nutrients more available to the plant. It can also prevent aluminum toxicity by making aluminum less soluble in the soil. Many soils in Virginia are high in aluminum, which stunts the growth of plant roots. MAINTENANCE: Even with careful, well -planned seeding operations, failures can occur. When it is clear that plants have not germinated an an area or have died, these areas must be reseeded immediately to prevent erosion damage. However, it is ""cutely important to determine for what reason germination did not take place and make any corrective action' necessary prior to reseeding the area. Healthy vegetation is the most effective erosion control available. IN PLANNING FOR DUST CONTROL, LIMITING THE AMOUNT OF SOIL DISTURBANCE AT ANYONE TIME SHOULD BE A KEY OBJECTIVE. THEREFORE, PHASED CLEARING AND GRADING OPERATIONS AND THE UTILIZATION OF TEMPORARY STABILIZATION IN ACCORDANCE WITH MS #1 CAN SIGNIFICANTLY REDUCE DUST EMISSIONS. TEMPORARY MEASURES USED DURING CONSTRUCTION 1. VEGETATIVE COVER - IN AREAS SUBJECT TO LITTLE OR NO CONSTRUCTION TRAFFIC, A VEGETATIVELY STABILIZED SURFACE WILL REDUCE DUST EMISSIONS (SEE TEMPORARY SEEDING, STD. & SPEC. 3.31). 2. MULCH - WHEN PROPERLY APPLIED, MULCH OFFERS A FAST, EFFECTIVE MEANS OF CONTROLLING DUST. NOT RECOMMENDED FOR AREAS WITHIN HEAVY TRAFFIC PATHWAYS. BINDERS OR TACKIFIERS SHOULD BE USED TO TACK ORGANIC MULCHES (SEE MULCHING, STD. & SPEC. 3.35). 3. TILLAGE - THIS PRACTICE IS DESIGNED TO ROUGHEN AND BRING CLODS TO THE SURFACE. IT IS AN EMERGENCY MEASURE WHICH SHOULD BE USED BEFORE WIND EROSION STARTS. BEGIN PLOWING ON WINDWARD SIDE OF SITE. CHISEL -TYPE PLOWS SPACED ABOUT 12 INCHES APART, SPRING -TOOTHED HARROWS, AND SIMILAR PLOWS ARE EXAMPLES OF EQUIPMENT WHICH MAY PRODUCE THE DESIRED EFFECT. 4. IRRIGATION -THIS IS THE MOST COMMONLY USED DUST CONTROL PRACTICE. SITE IS SPRINKLED WITH WATER UNTIL THE SURFACE IS WET. REPEAT AS NEEDED. IT OFFERS FAST PROTECTION FOR HAUL ROADS AND OTHER HEAVY TRAFFIC ROUTES. 5. SPRAY -ON ADHESIVES - TREMENDOUS PROGRESS HAS BEEN MADE IN RECENT YEARS IN THE DEVELOPMENT OF PRODUCTS OF THIS TYPE. MOST ARE EFFECTIVE ON "MINERAL" SOILS AND ARE INEFFECTIVE ON "MUCK" SOILS. THESE COHERICS ARE DERIVED FROM A VARIETY OF COMPOUNDS, BOTH ORGANIC AND SYNTHETIC BASED. MANY OF THE ADHESIVES WILL WITHSTAND HEAVY TRAFFIC LOADS. THE ORGANICS INCLUDE DERIVATIVES FROM PINE TAR AND VEGETABLE GUM; SYNTHETICS MAY BE ACRYLIC OR PETROLEUM BASED. 6. STONE - STONE CAN BE USED TO STABILIZE ROADS OR OTHER AREAS DURING CONSTRUCTION USING CRUSHED STONE OR COARSE GRAVEL (SEE CONSTRUC11ON ROAD STABILIZATION, STD. & SPEC. 3.3). 7. BARRIERS - A BOARD FENCE, WIND FENCE, SEDIMENT FENCE, OR SIMILAR BARRIER CAN HELP TO CONTROL AIR CURRENTS AND BLOWING SOIL. PLACE BARRIERS PERPENDICULAR TO PREVAILING AIR CURRENTS AT INTERVALS OF ABOUT 15 TIMES THE BARRIER HEIGHT. WHERE DUST IS A KNOWN PROBLEM, EXISTING WINDBREAK VEGETATION SHOULD BE PRESERVED. 8. CALCIUM CHLORIDE - THIS CHEMICAL MAY BE APPLIED BY MECHANICAL SPREADER AS LOOSE, DRY GRANULES OR FLAKES AT A RATE THAT KEEPS THE SURFACE MOIST BUT NOT SO HIGH AS TO CAUSE WATER POLLUTION OR PLANT DAMAGE. APPLICATION RATES SHOULD Bill STRICTLY IN ACCORDANCE WITH SUPPLIERS' SPECIFIED RATES. PERMANENT METHODS 1. PERMANENT VEGETATION -THE APPLICATION OF PERMANENT SEEDING (SEE STD. & SPEC. 3.32) AND SAVING EXISTING TREES AND LARGE SHRUBS CAN HELP REDUCE SOIL AND AIR MOVEMENT FROM CONSTRUCTION SITES. 2. STONE - CRUSHED STONE OR COARSE GRAVEL CAN BE USED AS A PERMANENT COVER WHICH WILL PROVIDE CONTROL OF SOIL NOT TO SCALE EMISSIONS.

Areas which have been permanently seeded (see Std. & Spec. 3.32, PERMANENT areas susceptible to displacement. SEEDING) should be mulched immediately following seeding. Chemical soil stabilizers or soil binders should not be used alone for mulch. These materials are useful to bind organic mulches together to prevent displacement. There are other organic materials which make excellent mulches but are only available locally or seasonally. Creative use of these materials can reduce .costs. Avariety of manufactured SOIL STABILIZATION BLANKETS AND MATTING (see Std. & Spec. 3.36) have been developed for erosion control in recent years. Some of these Chemical Mulches and Soil Binders products can be used as mulches, particularly in critical areas such as waterways. They also may be used to hold other mulches to the soil surface. A wide range of synthetic, spray -on materials are marketed to stabilize and protect the soil surface. These are emulsions or dispersions of vinyl compounds, rubber or other substances The choice of materials for mulching will be based on the type of soil to be protected, site which are mixed with water and applied to the soil. They may be used alone in some cases conditions, season and economics.

Source: Va. DSWC MULCHING Ill - 353 IB - 350 1992 3.35 Application: Mulch materials shall be spread uniformly, by hand or machine. When spreading straw mulch by hand, divide the area to be mulched into approximately 1,000 sq. ft. sections and place 70-90 lbs. (1k to 2 bales) of straw in each section to facilitate uniform distribution. Mulch Anchoring: Straw mulch must be anchored immediately after spreading to prevent displacement. Other organic mulches listed in Table 3.35-A do not require anchoring. The following methods of anchoring straw may be used! 1. Mulch anchoring tool (often referred to as a Krimper or Krimper Ti This is a tractor -drawn implement designed to punch mulch into the soil surface. This method provides good erosion control with straw. It is limited to use on slopes no steeper than 3:1, where equipment can operate safely. Machinery shall be operated on the contour. 2. Fiber Mulch: A very common practice with widespread use today. Apply fiber mulch by means of a hydroseeder at a rate of 500-750 lbs./acre over top of straw mulch or hay. It has an added benefit of providing additional mulch to the newly seeded area. 3. Liquid mulch binders: Application of liquid mulch binders and tackifiers should be heaviest at edges of areas and at crests of ridges and banks, to prevent displacement. The remainder of the area should have binder applied uniformly. Binders may be applied after mulch is spread or may be sprayed into the mulch as it is being blown onto the soil. The following types of binders may be used: a. Synthetic binders - Formulated binders or organically formulated products may be used as recommended by the manufacturer to anchor mulch. * b. Asphalt - Any type of asphalt thin enough to be blown from spray equipment is satisfactory. Recommended for use are rapid curing (RC-70, RC-250, RC-800), medium curing (MC-250, MC-800) and emulsified asphalt (SS-1, CSS-1, CMS-2, MS-2, RS-1, RS-2, CRS-1, and CRS-2). Apply asphalt at 0.10 gallon per square yard (10 gal./1000 sq. ft. or 430 gal./acre). Do not use heavier applications as it may cause the straw to "perch" over rills. All asphalt designations are from the Asphalt Institute Specifications. * Note: This particular method is not used as commonly today as it once was in the past. The development of hydraulic seeding equipment promoted the industry III - 354 Field experience has shown that plastic netting, when used alone, does not retain soil moisture or modify soil temperature. In some cases it may stabilize the soil surface while III - 351 1992 3.35 to turn to synthetic or organically based binders and tackifiers. When this method is used, environmental concerns should be addressed to ensure that petroleum -based products do not enter valuable water supplies. Avoid applications into waterways or channels. 4. Mulch nettings: Lightweight plastic, cotton, or paper nets may be stapled over the mulch according to manufacturer's recommendations. 5. Peg and twine: Because it is labor-intensive, this method is feasible only in small areas where other methods cannot be used. Drive 8- to 10-inch wooden pegs to within 3 inches of the soil surface, every 4 feet in all directions. Stakes may be driven before or after straw is spread. Secure mulch by stretching twine between pegs in a criss-cross-within-a square pattern. Turn twine 2 or more times around each peg. Chemical Mulches Chemical mulches* may be used alone only in the following situations: a. Where no other mulching material is available. b. In conjunction with temporary seeding during the times when mulch is not required for that practice. C. From March 15 to May 1 and August 15 to September 30, provided that they are used on areas with slopes no steeper than 4: 1, which have been roughened in accordance with SURFACE ROUGHENING, Std. & Spec. 3.29. If rill erosion occurs, another mulch material shall be applied immediately. * Note: Chemical mulches may be used to bind other mulches or with fiber mulch in a hydroseeded slurry at any time. Manufacturer's recommendations for application of chemical mulches shall be followed. Maintenanc All mulches and soil coverings should be inspected periodically (particularly after rainstorms) to check for erosion. Where erosion is observed in mulched areas, additional mulch should be applied. Nets and mats should be inspected after rainstorms for dislocation or failure. If washouts or breakage occur, re -install netting or matting as necessary after repairing damage to the slope or ditch. Inspections should take place up until grasses are firmly established. Where mulch is used in conjunction with ornamental plantings, inspect periodically throughout the year to determine if mulch is maintaining coverage of the soil surface; repair as needed. IB - 355 1992 3.35 grasses are being established, but is primarily used in grassed waterways and on slopes to hold straw or similar mulch in place. Jute mesh and other soil stabilization blankets are good choices for mulching on difficult slopes and in minor drainage swales. Most of the soil stabilization mattings (used to create a permanent matrix for root growth within the soil) must receive mulching in order to properly stabilize an area. Notably, some manufacturers have recently developed permanent mattings which include self-contained, temporary mulching materials; however, these measures will have to meet the requirements noted in Std. & Spec. 3.36, SOIL STABILIZATION BLANKETS AND MATTING, before they can be recommended for use on steep slopes and in channel flow situations. The most critical aspect of installing blankets and mats is obtaining fnn, continuous contact between the material and the soil. Without such contact, the material may fail and thereby allow erosion to occur. It is important to use an adequate number of staples and make sure the material is installed properly in order to maximize soil protection. These products are discussed in more detail in Std. & Spec. 3.36, SOIL STABILIZATION BLANKETS & MATTING. Organic Mulches Organic mulches may be used in any area where mulch is required, subject to the restrictions noted in Table 3.35-A. Materials: Select mulch material based on site requirements, availability of materials, and availability of labor and equipment. Table 3.35-A lists the most commonly used organic mulches. Other materials, such as peanut hulls and cotton burs, may be used with the permission of the local Plan -Approving Authority. Prior to mulching: Complete the required grading and install needed sediment control practices. Lime and fertilizer should be incorporated and surface roughening accomplished as needed. Seed should be applied prior to mulching except in the following cases: a. Where seed is to be applied as part of a hydroseeder slurry containing fiber mulch. b. Where seed is to be applied following a straw mulch spread during winter months. III - 352 Dig With QQQ© 2.

Conditions Where Practice Applies Generally applicable to flowing streams with drainage areas less than one square mile. Structures or methodology for crossing streams with larger drainage areas should be designed by methods which more accurately define the actual hydrologic and hydraulic parameters which will affect the. functioning of the structure. A Diversion Chanl may be utilized to "work in the dry". III - 227 1992 3.25 Planning Considerations Utility construction, by virtue of its sprawling, linear nature, frequently crosses and impacts live streams. There is a potential for excessive sediment loss into a stream by both the disturbance of the approach areas and by the work with the stream -bed and banks. It is often a difficult task to decide what type of control to use as a utility stream crossing. A method such as the "boring and jacking' of pipe below a streambed, which would prevent disturbance within the watercourse, is a preferred method if it is practical. However, in cases where in -stream work is unavoidable, consideration must be given to providing adequate mitigation of sediment loss while minimizing the amount of encroachment (MS #12) and time spent working in the channel. Tbere is some "give and take" as far as the installation of controls - sometimes there is less damage to the environment created by providing substantial controls for the approach areas and refraining from installing extensive measures in the stream itself. However, when the installation of the utility line within streambed and banks will take an extended period of construction time, consideration should be given to substantial in -stream controls or stream diversion in order to prevent excessive sedimentation damage. As a result of the difficulty in choosing the right method for a utility stream crossing, designers and plan reviewers should always make site visits of proposed crossing to ensure that the most appropriate method is chosen. The designer and plan reviewer should also be aware that such modifications are subject to other state and federal construction permits. The following are several methods for dealing with utility stream crossings (with varying construction time and stream size scenarios) which allow for "work in the dry" to prevent excessive sedimentation damage. By no means are these methods all-inclusive. As with other control measures, site -specific design and innovative variations are encouraged. Design Criteria (All methods) 1. The drainage area should be no greater than one square mile (640 acres). 2. All filter cloth used in the construction of the utility crossing must conform to physical requirements noted in Std. & Spec. 3.19, RIPRAP. 3. Water diverting structures should be used at all trenching and/or construction road approaches (50 feet on either side of the crossing) as per Std. & Spec. 3.24, VEHICULAR STREAM CROSSING. 4. Design criteria more specific to -each particular crossing can be found in Plates 3.25-1 through 3.25-4.
