In such case the CONTRACTOR shall not be entitled to receive any further payment until the WORK is finished. if the unpaid balance of the CONTRACT PRICE exceeds the direct and indirect costs of completing the PROJECT, including compensa- tion for additional professional services, such excess SHALL BE PAID TO THE CONTRACTOR. If such costs exceed such unpaid balance, the CONTRACTOR will pay the difference to the OWNER. Such costs incurred by the OWNER will be determined by the ENGINEER and incorporated in a CHANGE ORDER. 18.3 Where the CONTRACTOR'S services have been so terminated by the OWNER, said termination shall not affect any right of the OWNER against the CON- TRACTOR then existing or which may thereafter ac- crue.

The ENGINEER will, within ten (10) days after receipt of each partial pay- ment estimate, either indicate in writing his approval of payment and present the partial payment estimate to the OWNER, or return the partial payment estimate to the CONTRACTOR indicating in writing his reasons for refusing to approve payment. In the latter case, the CONTRACTOR may make the necessary corrections and resubmit the partial payment estimate. The OWN- ER will, within ten (10) days of presentation to him of an approved partial payment estimate, pay the CON- TRACTOR a progress payment on the basis of the ap- proved partial payment estimate.

Such use shall not constitute an acceptance of such portions of the WORK. 19.4 The OWNER shall have the right to enter the premises for the purpose of doing work not covered by the CONTRACT DOCUMENTS. This provision shall not be construed as relieving the CONTRACTOR of the sole responsibility for the care and protection of the WORK, or the restoration of any damaged WORK ex- cept such as may be caused by agents or employees of the OWNER. 19.5 Upon completion and acceptance of the WORK, the ENGINEER shall issue a certificate attached to the final payment request that the WORK has been ac- cepted by him under the conditions of the CONTRACT DOCUMENTS.

NER to either the CONTRACTOR, his Surety, or any third party. In paying any unpaid bills of the CONTRACTOR, any payment so made by the OWNER shall be considered as a payment made under the: CONTRACT DOCUMENTS by the OWNER to the CONTRACTOR and the OWNER shall not be liable to the CONTRACTOR for any such payments made in good faith. 19.7 If the OWNER fails to make payment thirty (30) days after approval by the ENGINEER, in addition to other remedies available to the CONTRACTOR, there shall be added to each such payment interest at the maximum legal rate commencing on the first day after 19.2 The request for payment may also include an said payment is due and continuing until the payment allowance for the cost of such major materials and is received by the CONTRACTOR.

GE,7ERAL The work covered by this Section consists of furnishing all labor, equipment and materials and performing all operations in connection with the construction of sewage force mains, sanitary sewers, manholes, and sewer appurtenances as shown on the drawings, as specified and as directed by the Engineer. Lines shall begin and terminate at the locations shown on the plans. 2. EARTHT.joR_< Excavation, trenching and back=filling for all piping specified herein shall conform to the applicable requirements of Section II, Earthwork, and any special requirements as indicated on the drawings. 3. MATERIALS Materials shall conform to the specifications of Section IV, Piping, Fittings and Valves. 4 . INSTALLATIC,1 a. General t • Pipe and fittings shall be strung out along the route of construc- ticn with the bells facing in the direction in which the work is to proceed. Pipe shall be placed where it will cause least interference with traffic. Where applicable, this work shall conform to the provisions of Section II, Earthwork. Laying of the pipe shall be commenced immediately after the excavation is started and every means must be used to keep pipe laying closely behind the trenching. The Engineer may stop the trenching when, in his opinion, the trench is open too far in advance of the pipe laying opera- tion. The bottom of the sewer trench shall be shaped to give substantially uniform Circumferential su_ocort to the lower one-third of each pipe. Holes shall be scooped out where the bells occur leaving the entire barrel of the e bearing on the pi_e bed. Each pipe she__ be inspected for defects prior to being lowered into the trench and swabbed'.r brushed out to insure that no dirt or foreign material gets into the finised line. Trench waters shall -be kept out of the pipe and the pipe kept closed wor:: is not in progress. P by means of a test plug whenever g_ess. Pipe shall be handled carefully to avoid breakage. Pipe may be laid in the best manner adsnted to securing speed and good results. However, it shall be laid in accordance with the -manufacturer's s instructions and reco,=e^dations. Bell l and spigot PiE:e laying shall rope_ spigot ends pointi proceed u_grad_ with .ng in direction of flow. If the moximuj trench width • VI-1 specified in Section II, Earthwork, is exceeded for any reason other than by order of the Engineer, the Contractor shall install e ' =11 at his own expense, concrete cradling, pipe encasement or other bedding as may be reeuired by the Engineer to sup_ort the load of the back,;:411. Backfilling shall be tamped conforming to the requirements specified in the Eart::.gor:c Section of these specifications. b. Gravity Sewers Installation of gravity sewer pipe and fittings with factory made joints shall be accomplished in strict accordance with the manufacturer's recommendation and the Engineer's approval. Joints shall be clean before assembly. Pipe alignment shall ccnform to the requirements set fort:; in the paragraph for "Sewer Inspection and Test" of this section. C. Sewage Force Mains Where it is necessary to cut the pipe to place special castings care must be taken not to crack the pipe and to cut straight and true around it. Force mains shall be thrust blocked at bends to prevent movement of lines under pressure. The concrete blocking shall be placed between solid ground and the fittings anchored in such a manner that the pipe and fitting joints will be accessible for repairs. Concrete shall be 2500 lb. concrete. All joints shall be watertight (refer to Paragraph 7, Inspection and Tests ) and any leaks or defects discovered shall be immediately repaired to the satisfaction of the Engineer. Any pipe which has been disturbed after being laid shall be taken up, the joints cleaned, and the pipe properly relaid. Damaged or unsound pipe or fittings will -be rejected. Before jointing the pipe, all lumps, material and any dirt or sand shall be removed fromsthesbellcess spigotating ends Of pipes. Any superfluous material inside the pipe shall be removed by means of an approved follower or scraper after joints are made. Where necessary to deflect the Pipe from a straight lne at joints, the deflection • shall not exceed that recommended bythe1manufacturer. If the specified or required alignment requires deflections in excess Of those recommended, the Contractor shall either provide special bends as approved by the Engineer or a sufficient number of shorter lengths of pipe to provide_ ancrular deflections within the ; the manufacturer.

Water ;Mains *fear Sewers (1) Horizontal Separation: Wherever possible sewer be laid at least 10 feet, se�c�_ lines horizontally, from any existing or proposed drain sewer line. Should local conditions prevent a lateral separation of 10 fie+, a sewer line may be laid closer than 10 feet to (or in the sarc trench as) a water line provided that the line is laid in a separate trench, or on an undisturbed earth shelf location on one side of the sewer at suc:^, an elevation that the bottom of the water main is at least 18 inc :es above the top of the sewer. When it is impossible to obtain proper horizontal and vertical separation as stipulated above, both the :vater main and server should be constructed of slip-on or mechanical joints, cast iron pipa, asbestos-_ cement pressure pipe, or prestressed concrete cylinder pipe, and should be� pressure tested to assure watertightness before bacfilli_ng. (2) Vertical Separation: Wherever sewer lines the water main shall be not less than 18 inches above thectoo-o`at`�e seiQs: This vertical separation should be maintained for that portion of t e water main located within 10 feet horizontally of any sewer line being laid there_ under said 10 feet to be measured as the normal distance from the to the sewer. ;cater main (3) Unusual Condition._: vertical SepaWhere conditions prevent the mini=,z.-j ration set forth In su paragraph (2) from being -ma'ntained'or when it is necessary for the sewer line to be installed over a water main, the server line shall be laid with mechanical joint cast iron pipe, testes: to 50 the peroprio r to placing in Operation, and the pipe shall extend on. each side or g 1 the no r-ia7 distance from the sewer line to the water mai is at least 10 feet.

Where an open cut is eermiss_ble in VI-5 crossing the State Highway instead of boring, the Contractor shall mate the necessary provisions for handling traffic and replacing the road bed and surface as required by the Virginia Department of Highways. 7. INSPECTION AND TSSTS a. Watertight Ccnstr ct� on It is imperative that all sewers and force mains, manholes and service connections be built practically watertight and that the Contractor adhere rigidly to the specifications for material and workmanship. All of the sewage must be pumped for treatment and special care and attention must be given to securing watertight construction. After completion, the sewers or sections thereof will be air tested for infiltration and if either is above allowable limits specified, the sewer will be rejected. All equipment, materials and manpower required for testing in accordance with these specifications shall be furnished by the Contractor. All testing shall be performed under the supery ision o.. the Owner and/or t-e Engineer. It is the intent of these specifications to produce a sewer lin* with infiltration not exceeding 100 gallons per day per inch of diameter per mile of sewer length. sewer b. Insoect,nn On completion of each block or section of sewer (including all service laterals) or such other time as the Engineer may direct, t^e repairs shown necessary by the test are to be left true to ling and crap - clean and ready for use. Each section of sewer bet;Jeen manholes is to show from either end on examination a full circle of light. C. Sanitary Sewer Testing (The following is excerpted from the Joh.Is' Manville Sewer Pipe Manual). All testing must be in accordance with AST`, C828 as required by Commonwealth of Virginia "Sewage Regulations" Secti 21.05.08, Paragraph 3. on Test is conducted between two (2) consecutive manholes, as directed by the Engineer. •� The test section of the sewer line is Pluggedhd_ the plugs used at the manhole must be tapped and equipped for theairOinlne �' connection for filling the line from the air compressor. All service laterals, stubs and fittings into the sewer test section should be properly capped or plugg=d, and care=ally bra -zed ac list the internal pressure to prevent air leakage by slippage and b1o:Jouts. Connect air hose to tapped plug selected for the air inlet. Then connect the other end OFf the air hose to the portable air control equipment which consists of valves and pressure gages used to control the air entry rate to the sewer test section, and to monitor the air pressure in the pipe line. More specifically, the air control ecu;pment include a shut-off valve, pressure reguiating valve, pressure reduction valve an= a monitoring pressure gage having a u pressure range from 0 to 5 psi. Thegaye should have minimum divisions of .10 psi and an accuracy of *.Os psi. Figur No. 110 illustrates diagr3..-zatical1;, a ty^ical control eeu;=ment apparatus. VI-o (Revised June 1983) Connect another air nose between the air compressor (or ether fo source of commressed air) and the air control equipment. This co^pletes the test equipment set-up. Test operations may o co^men c� . fo Supply air to the test section slowly, filling the pine lire until a constant pressure of 3.5 psi is maintained, The air pressure must ; regulated to prevent the pressure inside the pine from exceeding 5.0 osia. When constant pressure of 3.5 psig is reached, throttle the air su:,ply to maintain the internal pre above 30 psi ' pressure a ov .g for at least 5 minutes. This time Permits the temperature of the entering air to equalize with the temperature of the pipe wall. During this stabilization period it is advisabl. to check all capped and plugged fittings with a soap solution to detect any leakage at these connections. If leakage is detected at any cap or plug, release the pressure in the line and tighten all leaky cams and Plugs. Then start the test ope again by sunmlvin air. rati_ q When it is necessary to bleEd off the air to tight_n or repair a faulty plug, a new five-minute interval must be allowed after the Pipe line has been refilled. After the stabilization period, adjust the aire pressure to 3.5 psig and shut off or disconnect the air supply. Observe the gage until the aire pressure reaches 3.0 Psig. At 3.0 psig commence timing with a stoo watch which is allowed to run Until the line pressure drops to 2.5 psig at which time the stop watcl, is stropped. The time recuid as s the pressure stop watch, fora r reshown on P loss oL 0.5 psig is used to compute the air loss. Most authorities consider it unnecessary to determine the air temperature inside the pipe line and the barometric pressure at the the test, tine of If the time, in minutes and seconds, for the air pressure to drop from 3.0 to 2.5 psig is greater than that shwon in Table Y for the designated pi_ size, the section ands_ shall be presumed to be free r going test shall have passed and • of defects.

Section 22.07 of the Re;ulations is t:^.e particul _ section and the contractor should be thoroughly familiar with it. In su_:mary, L = (N x D xF)/3700, where L is the allowable leakage in gallons per hour, N is the number of pipe joints, D is the pipe diameter in inches, and P is the test pressure in psi. All force mains shall be tested at a m4ni7,_"t pressure of at least 50 percent above the design operating pressure, for at least 30 minutes. The Contractor must furnish all necessary equipment and shall bear the cost of testing the force mains. All tests shall be made in the presence of the Engineer. e. Manholes 40 Inflatable stoppers shall be used to plugall l _;ne s into and cut of the manhole being tested. The stoccens shall _ be positioned in the lines far enough from the manhole to insure testing of those portions of th_ lines not air tested. The manhole shall then.. be filled with water to th e top. A 12-hour soak shall be allowed. Leakage shall not exceed per hour. g�__on 40- VI-9 (Revised June, 1983) 46 INDEX SECTION VII DISINFECTION AND TESTS Paraqravh No. Paae No. 1 General VI-1 2 Disinfecting Agent VI-1 3 Disinfection Methods VI-1 4 Approval of Disinfection VI-2 0 • 0, • 11 DETAILED SPECIFICATIONS SECTION VII DISINFECTION AND TESTS 1.

Planning Considerations Topsoil is the surface layer of the soil profile, generally characterized as being darker than the subsoil due to the presence of organic matter. It is the major zone of root development, carrying much of the nutrients available to plants, and supplying a large share of the water used by plants. Although topsoil provides an excellent growth medium, there d,sodvan- tages to its use. Stripping, stockpiling, reapplying g topsoi importing topsoil, may not always be cost-effective. Topsoiling can . delay seeding or sodding operations, increasing the exposure time of denuded areas. Most topsoil contains weed seeds, and weeds may with desirable species. Advantages of topsoil include its high organic matter content and friable consistence, water -holding capacity, and nutrient content. In site planning, the option of topsoiling should be compared with that of preparing a seedbed in subsoil. The clay content of subsoils doe-7 of ts provide high moisture availability and deter leachingaugoodngrowthd when properly limed and fertilized, subsoils may provide medium which is generally free of weed seeds. Topsoiling is strongly recommended where ornamental plants or hlwhenain- tenance turf will be grown. Topsoiling is a required P potentiallyning establishing vegetation on shallow soils, soils contiacid)evels. toxic materials, and soils of critically low pH (high If topsoiling is to be done, the following items should be considered: 1. Whether an adequate volume of topsoil exists on the site. Topsoil will be spread at a compacted depth of 2-4 inches. 2. Location of the topsoil stockpile so that it meets specifications and does not interfere with work on the site. 3. Allow sufficient time in scheduling for topsoil to be spread and bonded prior to seeding, sodding, or planting. 4. Care must be taken not to a 1 topsoil tops° l over sandy subsoil is subsoil if the two 1ls have contrasting textures. Clayey P a particularly poor combination, as water creeps along the junction between the soil layers and causes the topsoil to slough. III-208 1980 1.61 5. If topsoil and subsoil are not properly bonded, water will not infil- trate the soil profile evenly and it will be difficult to establish vegetation. Specifications Materials Field exploration of the site shall be made to determine if there is sufficient surface soil of good quality to justify stripping. Topsoil shall be friable and loamy (loam, sandy loam, silt loam, sandy clay loam, clay loam). It shall be free of debris, trash, stumps, rocks, roots, and noxious weeds, and shall give evidence of being able to support healthy vegetation. It shall contain no substance that is potentially toxic to plant growth. All topsoil shall be tested by a recognized laboratory for the following • criteria: Organic matter content shall be not less than 1.5% by weight. pH range shall be from 6.0-7.5. If pH is less than 6.0, lime shall be added in accordance with soil test results or in accordance with the recommendations of the vege- tative establishment practice `:eing used. Soluble salts shall not exceed 500 ppm. If additional off -site topsoil is needed, it must meet the standards stated above. Stripping Stripping shall be confined to the immediate construction area. A 4- to 6-inch stripping depth is common, but depth may vary depending on the particular soil. All perimeter dikes, basins, and other sediment Is controls shall be in place prior to stripping. Stockpiling Topsoil shall be stockpiled in such a manner that natural drainage is not obstructed and no off -site sediment damage shall result. Side slopes of the stockpile shall not exceed 2:1. A perimeter dike with gravel outlet, silt fence, or straw bale barrier shall surround all topsoil stockpiles. Temporary seeding of stockpiles shall be completed within 15 days of the formation of the stockpile, in accordance with TEMPORARY SEEDING (Std. & Spec. 1.65). Site Preparation Prior to and Maintenance During Topsoiling • Before topsoiling, establish needed erosion and sediment control practices III-209 M R r 1.61 such as diversions, grade stabilization structures, berms, dikes, level spreaders, waterways, sediment basins, etc. These practices must be • maintained during topsoiling. Grading: Previously established grades on the areas to be topsoiled shall be maintained according to the approved plan. Liming: Where the pH of the subsoil is 6.0 or less, or the soil is com- posed of heavy clays, agricultural limestone shall be spread in accord- ance with the soil test or the vegetative establishment practice being used. Bonding: After the areas to be topsoiled have been brought to grade, and immediately prior to dumping and spreading the topsoil, the subgrade shall be loosened by discing or scarifying to a depth of at least 2 inches to insure bonding of the topsoil and subsoil. AoDlvinq Topsoil Topsoil shall not be placed while in a frozen or muddy condition, when • the subgrade is excessively wet, or in a condition that may otherwise be detrimental to proper grading or proposed sodding or seeding. The topsoil shall be uniformly distributed to a minimum compacted depth of 2 inches on 3:1 or steeper slopes and 4 inches on flatter slopes. (See Table 1.61a to determine volume of topsoil required for application to various depths). Any irregularities in the surface, resulting from top - soiling or other operations, shall be corrected in order to prevent the formation of depressions or water pockets. It is necessary to compact the topsoil enough to ensure good contact with the underlying soil and to obtain a level seedbed for, the establish- ment of high maintenance turf. However, undue compaction is to be avoided as it increases runoff velocity and volume, and deters seed germination. In areas which are not going to be mowed, the surface should be left, rough in accordance with SURFACE ROUGHENING (Std & Spec. 1.60). • Soil Sterilants No sod or seed shall be placed on soil which has been treated with soil sterilants until sufficient time has elasped to permit dissipation of toxic materials.

Purposes 1. To reduce erosion and sedimentation by stabilizing disturbed areas that will not be brought to final grade for a year or less. 2. To reduce problems associated with mud and dust production from bare soil surfaces during construction. Conditions Where Practice Applies Where exposed soil surfaces are not to be fine -graded for periods from 30 days to one year. Such areas include denuded areas, soil stockpiles, dikes, dams, sides of sediment basins, temporary roadbanks, etc. (See GENERAL CRITERIA GC-1). •:1 1.65 ' Planning Considerations Sheet erosion, caused by the impact of rain on bare soil, is the source • of most fine particles in sediment. To reduce this sediment load in runoff, the soil surface itself should be protected. The most efficient and economical means of controlling sheet and rill erosion is to establish vegetative cover. Annual plants which sprout rapidly and survive for only one growing season are suitable for establishing temporary vegeta- tive cover. Temporary seeding may prevent costly maintenance operations on other erosion control systems. For exaj„pie, sediment basin clean -outs will be reduced if the drainage area of the basin is seeded where grading and construction are not taking place. Perimeter dikes will be more effective if not choked with sediment. Temporary seeding is essential to preserve the integrity of earthen struc- tures used to control sediment, such as dikes, diversions, and the banks and dams of sediment basins. • Proper seedbed preparation and the use of quality seed are important in this practice just as in permanent seeding. Failure to carefully follow sound agronomic recommendations will often result in an inadequate stand of vegetation that provides little or no erosion control. Specifications Prior to seeding, install necessary erosion control practices such as aikes, waterways, and basins. Plant Selection Select plants appropriate to the season and site conditions from Table 1.65a. • Seedbed Preparation To control erosion on bare soil surfaces, plants must be able to germi- nate and grow. Seedbed preparation is essential. 1. Liming: Where soils are known to be highly acid (pH 5.5 and lower), Time should be applied at the rate of two tons of pulverized agricul- tural limestone per acre. 2. Fertilizer: Shall be applied as 450 lbs./acre of 10-20-20 (10 lbs./1,000 sq. ft.T or equivalent. Lime and fertilizer shall be incorporated into the top 2 to 4 inches of the soil. 3. Surface Roughening: If the area has been recently loosened or dis- turbed, no further roughening is required. 1� III-212 1980 1.65 When the area is compacted, crusted, or hardened, the soil surface shall be loosened by discing, raking, harrowing, or other acceptable • means. (See SURFACE ROUGHENING, Std. & Spec. 1.60) 4. Tracking: Tracking with bulldozer cleats is most effective on sandy soils. This practice often causes undue compaction of the soil sur- face, especially in clayey soils, and does not aid plant growth as effectively as other methods of surface roughening. Seeding Seed shall be evenly applied with a cyclone seeder, drill, cultipacker seeder or hydroseeder. Small grains shall be planted no more than one inch deep. Grasses and legumes shall be planted no more than 1/4 inch deep. Mulching 1. Seedings made in fall for winter cover shall be mulched according • to MULCHING, Std. & Spec. 1.75, except that hydromulches (wood fiber) will not be considered adequate. 2. At other times of the year, Seedings made on slopes in excess of 4:1, or on adverse soil conditions, or during excessively hot or dry weather, shall be mulched according to MULCHING, Std. & Spec. 1.75. 3. Seedings made during optimum spring and summer seeding dates, with favorable soil and site conditions, will not require mulch. U • Re -seeding Areas which fail to establish vegetative cover adequate to prevent rill erosion will be re -seeded as soon as such areas are identified.

Purposes 1. To reduce erosion and decrease sediment yield from disturbed areas. 2. To permanently stabilize disturbed areas in a manner that is economi- cal, adaptable to site conditions, and allows selection of the most appropriate plant materials. Conditions Where Practice Applies 1. Disturbed areas where permanent, long-lived vegetative cover is needed to stabilize the soil. 2. Rough -graded areas which will not be brought to final grade for a year or more. III-215 •21 1.66 Planning Considerations Vegetation controls erosion by reducing the velocity and the volume of • overland flow and protecting the bare soil surface from raindrop impact. Areas which must be stabilized after the land has been disturbed require vegetative cover. The most common and economical means of establishing this cover is by seeding grasses and legumes. Advantages of seeding over other means of establishing plants include the small initial establishment cost, the wide variety of grasses and legumes avail-ble, low labor requirement, and ease of establishment in difficult areas. Disadvantages which must be dealt with are the potential for erosion during the establishment stage, a need to reseed areas that fail to estab- lish, limited periods during the year suitable for seeding, and a need for water and appropriate climatic conditions during germination. There are so many variables in plant growth that an end product cannot • be guaranteed. Much can be done in the planning stages to increase the chances for successful seeding. Selection of the right plant materials for the site, good seedbed preparation, and conscientious maintenance are important. SELECTING PLANT MATERIALS: The factors affecting plant growth are cli- mate, soils, and topography. In Virginia, there are three major physio- graphic regions that reflect changes in soil and topography. In select- ing appropriate plant materials, one should take into account the char- acteristics of the physiographic region in which the project is located. (See Plate 1.66a). P YS1`0'A ."FIC REGIONS: Coastal Plain --Soils on the coastal plain are deeply weathered, stra- • tified deposits of sand and clay. They are generally acid and low in plant nutrients. The sandy soils are hot and droughty in summer. This region receives more rain and is warmer than the other regions of the State. The land is fairly level and many areas are poorly drained. Piedmont --Soils on the Piedmont plateau are highly variable. They tend to be shallow, with clayey subsoils. Piedmont soils are low in phosphorus. Soils derived from mica schist are highly erodible. Topography is rolling and hilly. The southern Piedmont has much the same climate as the Coastal Plain. Appalachian and Blue Ridge Region --This region is divided into pla- teaus, mountains, and narrow valleys. Soils tend to be shallow and acid, and may erode rapidly on steep slopes. Shaley slopes are often unstable and droughty. This area is colder and drier than the rest of the State. The rugged topography makes plant establishment difficult. III-216 -o a rt Appalachian Piedmcnt Coastal Plain PHYSIOGRAPHIC PROVINCES OF VIRGINIA J rn •il 1.66 SOILS: On the whole, soils in Virginia (N) fertilization to establish plants. W are usually needed. Except for some stone soils, lime is universally needed. always require some nitrogen Phosphorus (P) and potassium small pockets of shallow lime- . Soils can be modified with lime and fertilizer, but climate cannot be controlled. For this reason, the State has been divided into two major climatic regions, referred to as the Northern Piedmont and Mountain Region and the Southern Piedmont and Coastal Plain Region, for grass and legume selection. (See map, Plate 1.66b) Microclimate, or localized climate conditions, can affect plant growth. A south -facing slope is drier and hotter than a north -facing slope, and may require drought -tolerant plants. Shaded areas require shade -tolerant plants; the windward side of a ridge will be drier than the leeward, etc. LAND USE: A prime consideration in selecting which plants to establish is the intended use of the land. All of these uses --residential, indus- trial, commercial, recreational --can be separated into two categories: • High -maintenance and low -maintenance. High -maintenance arE,:�7 :-_'_'1 be mowed frequently, limed and fertilized regularly, and will either receive intense use (e.g., athletics) or re- quire maintaining to an aesthetic standard (home lawns). Grasses used for these situations must be fine -leaved and attractive in appearance, able to form tight sod, and be long-lived perennials. They must be well - adapted to the geographic area where they are planted, because constant mowing puts turf under great stress. Sites where high -maintenance vege- tative cover is desirable include homes, industrial parks, schools, churches, and some recreational -areas. Low -maintenance areas will be mowed infrequently or not at all; lime and fertilizer may not be applied on a regular basis; the areas will not be subjected to intense use, nor required to have a uniform appear- ance. These plants must be able to persist with little maintenance over long periods of time. Grass and legume mixtures are favored for these sites because legumes are capable of fixing nitrogen from the air for their own use, and the use of the plants around them. Such mixed stands are better able to withstand adverse conditions. Sites that would be suitable for low -maintenance vegetation include steep slopes, stream or channel banks, some commercial properties, and "utility turf• areas such as roadbanks. 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 6.0-7.0. Sufficient nutrients --added as fertilizer --must be present. After seed is in place, it must be protected with a mulch to hold mois- ture and modify temperature extremes, and to prevent erosion while seed- lings are growing. • 9' III-218 I M 1.66 The af7( ;,:ion 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 plant roots. MAINTENANCE - Even with careful, well planned seeding operations, fail- ures can occur. When it is clear that plants have not germinated on an area or have died, these areas must be reseeded immediately to prevent erosion damage. Healthy vegetation is the most effective erosion preventive available. Specifications Selection of Plant Materials 1. Selection of plant materials is based on climate, topography, soils, land use, and planting season. To determine which plant materials are best adapted to a specific site, use Tables 1.66c and 1.66d, which descritc plant characteristics and list recommended varieties. 2. Appropriate seeding mixtures for various site conditions in Virginia are given in Tables 1.66a and 1.66b. These mixtures are designed for general use, and are known to perform well on the sites described. Adhere to these mixtures whenever feasible. Check Tables 1.66c and 1.66d for recommended varieties. 3. Virginia CropImprovement Association recommended turfgrass mixtures may also be used. These will bear a label indicating that they are approved by the Association. They are designed to be used in high - maintenance turf areas.

To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a growth medium. The existing soil must have these criteria: 1. enough fine-grained material to maintain adequate moisture and nutri- ent supply. 2. sufficient pore space to permit root penetration. A bulk density of 1.2 to 1.5 indicates that sufficient pore space is present. A fine granular or crumb -like structure is also favorable. 3. sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable layers such as hardpans shall be 12 inches or more, except on slopes steeper than 2:1 where the addition of soil is not feasible. • 4. a favorable pH range for plant growth. If the soil is so acid that a pH range of 6.0-7.0 cannot be attained by addition of pH -modifying materials, then the soil is considered an unsuitable environment for plant roots. 5. freedom from toxic amounts of materials harmful to plant growth. 6. freedom from excessive quantities of roots, branches, large stones, large clods of earth, or trash of any kind. Clods and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded. If any of the above criteria cannot be met, i.e., if the existing soil is too coarse, dense, shallow, acid, or contaminated to foster vegetation, then topsoil shall be applied in accordance with TOPSOI INU Std. & Spec. 1.61. • Necessary mechanical erosion and sediment control practices will be in- stalled prior to seeding. Grading will be carried out according to the approved plan. • Surfaces will be roughened in accordance with SURFACE ROUGHENING, Std. & Spec. 1.60. Soil Conditioners In order to modify the texture, structure, or drainage characteristics of a soil, the following materials may be added to -the soil: 1. Peat shall be sphagnum moss peat, hypnum moss peat, reed -sedge peat or peat humus, from fresh -water sources. Peat shall be shredded and conditioned in storage piles for at least six months after exca- vation. III-221 m 1.66 2. Sand shall be clean and free of toxic materials. • 3. Vermiculite shall be horticultural grade and free of toxic substances. 4. Rotted manure shall be stable or cattle manure not containing undue amounts of straw or other bedding materials or toxic chemicals. 5. Thoroughly Rotted sawdust shall have 6 lbs. of nitrogen added to each cubic yard and shall be free of stones, sticks, and toxic sub- stances. 6. Where local ordinances permit, treated sewage sludge may be used in accordance with local, state, and federal regulations. Lime and Fertilizer Lime and fertilizer needs should be determined by soil tests. Soil tests may be performed by the Cooperative Extension Service Soil Testing Labora- • tory at VPI & SU, or by a reputable commercial laboratory. Information concerning the State Soil Testing Laboratory is available from county extension agents. Under unusual conditions where it is not possible to obtain a soil test, the following soil amendments will be applied: LIME: Coastal Plain: 2 tons/acre pulverized agr #ultural dolomite (90 lbs./1000 ft.`). Piedmont and Appalachian Region: 3 tons/acre pulverized agricultural limestone (140 lbs./1000 ft. ) FERTILIZER: Mixed grasses and legumes: 1200 lbs./acre 5-20-10 (25 lbs./1000 ft. ) • Legume stands only: 1002 lbs./acre 5-20-10 (25 lbs./ 1000 f t . ) Grass stands only: 1000 lbs./acre 5-20-10 and 300 jbs. of 38-0-0 in spring (7 lbs/1000 ft. ). 1000 lbs./acre 10-20-10 and 300 Ps. of 38-0-0 in fall. (7 lbs./1000 ft. ) Other fertilizer formulations may be used, provided they can supply the same amounts and proportions of plant nutrients. Incorporation - Lime and fertilizer shall be incorporated into the top 4-6 inches of the soil by discing or other means. When applying lime and fertilizer with a hydroseeder, apply to a rough, loose surface. III-222 1980 • Seeding • 1.66 1. Certified seed will be used for all permanent seeding whenever possible. Certified seed is inspected by the Virginia Crop Improvement Associa- tion or the certifying agency in other states. The seed must meet published state standards and bear an official "Certified Seed" label (see Appendix 1.66A). VIRGINIA CROP IMPROVEMENT ASSOCIATION ILACKSEURA. VIRGINIA MEMBER OF ASSOCIATION OF OFFICIAL SEED CERTIFYING AGENCIES 2. Legume seed - Legume seed should be inoculated with the inoculant appropriate to the species. Seed of lespedezas, crown vetch, and clovers should be scarified to promote uniform germination. 3. Apply seed uniformly with a cyclone seeder, drill, cultipacker seed- er, or hydroseeder on a firm, friable seedbed. Maximum seeding depth • should be 1/4 inch. 4. Hydroseeding - To avoid seed damage, it is recommended that if a machinery breakdown of 30 minutes to 2 hours occurs, 50% more seed be added to the tank, based on the proportion of the slurry remaining in the tank. Beyond 2 hours, a full rate of new seed may be necessary. • Often hydroseeding contractors prefer not to apply lime in their rigs as it is abrasive. In inaccessible areas, lime may have to be applied in pelletized or liquid form, separately. Rates of wood fiber should be at least 2000 lbs. per acre. Surface roughening is particularly important when hydroseeding, as a roughened slope will provide some natural coverage of lime, fertilizer and seed. Legume inoculants should be applied at four times the recommended rate when inoculant is included in the hydroseeder slurry. III-223 M 1.66 Mulching All permanent seeding must be mulched immediately upon completion of • seed application. Refer to MULCHING, Std. & Spec. 1.75. Maintenance of New Seedinqs Irrigation: New seedings should be supplied with adequate moisture. Supply water as needed, especially late in the season, in abnormally hot or dry weather, or on adverse sites. Water application rates should be controlled to prevent runoff. Inadequate amounts of water may be more harmful than no water. Re -seeding: Inspect seeded areas for failure and make necessary repairs and reseedings within the same season, if possible. 1. If vegetative cover is inadequate to prevent rill erosion, over - seed and fertilize in accordance with soil test results. 2. If a stand has less than 40% cover, re-evaluate choice of plant . materials and quantities of lime and fertilizer. Re-establish the stand following seedbed preparation and seeding recommenda- tions, omitting lime and fertilizer in the absence of soil test results. NOTE: if vegetation has failed to grow, soil n,jst be tested to determine if acidity or nutrient imbalances are re- sponsible. Fertilization: Seedlings should be fertilized one year after planting to insure proper stand density. 1. To established al�-grass stands, apply 500 lbs./acre of 10-20-10 (12 lbs./1000 ft. ) between August 15 and November 15. (The first fall following seeding) 2. To legume -and -grass stands or2 pure legume stands, apply 500 lbs./acre of 0-20-20 (12 lbs./1000 ft. ) in early May or between August 15 - October 15. GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTAB- LISHED UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANT- ING. DISTURBED AREAS WHICH ARE TO BE STABILIZED WITH PERMANENT VEGETA- TION MUST BE SEEDED OR PLANTED WITHIN 15 DAYS AFTER FINAL GRADE IS REACHED UNLESS TEMPORARY STABILIZATION IS APPLIED.

Purposes 1. To establish permanent turf immediately. 2. To prevent erosion and damage from sediment and runoff by stabilizing the soil surface. 3. To reduce the production of dust and mud associated with bare soil surfaces. 4. To stabilize drainageways where concentrated overland flow will occur. Conditions Where Practice Applies 1. Disturbed areas which require immediate vegetative covers, or where sodding is preferred to other means of grass establishment. wlia III-231 M 1.67 2. Locations particularly suited to stabilization with sod are: -waterways carrying intermittent flow • -area around drop inlets in grassed swales -residential or commercial lawns where quick use or aesthetics are factors. Planning Considerations The successful establishment of quality turfgrass is difficult in Virginia. Extremes in temperature and moisture availability create severe stresses on both cool and warm seasc-= grasses. The selection of appropriate turf - establishment methods requires a great deal of forethought. A quality turf containing the recommended mixtures and species can be established with either seed or sod. Soil preparation for the two methods is the same. The advantages of properly installed sod include: 1. immediate erosion control 2. an instant green surface with no dust or mud 3. nearly year-round establishment capability 4. less chance of failure than with seed 5. freedom from weeds 6. quick use of the sodded surface 7. the option of buying a quality -controlled product with predict- able results. • It is initially more costly to install sod than to seed. However, this • cost is justified in places where sod can perform better than seed in controlling erosion. In swales and waterways where concentrated flow will occur, properly pegged sod is preferable to seed because there is no lag time between installation and the time when the channel is protected by vegetation. Drop inlets which will be placed in grassed areas can be kept free of mulch, seed, and mud, and the grade immediately around the inlet can be maintained, by framing the inlet with sod strips. Sod can be laid during times of the year when seeded grass may fail, so long as there is adequate water available for irrigation in the early weeks. Ground preparation and proper maintenance are as important with sod as with seed. Sod is composed of living plants and those plants must re- III-232 1980 1.67 • ceive adequate care in order to provide vegetative stabilization on a disturbed area. Specifications Soil Preparation 1. Prior to soil preparation, areas to be sodded shall be brought to final grade in accordance with the approved plan. 2. Soil tests should be made to determine the exact requirements for lime and fertilizer. Soil tests may be conducted by the State Lab- oratory at VPI & SU or a reputable commercial laboratory. Informa- tion on free state soil tests is available from county or city agri- cultural extension agents. • Under difficult circumstances where it is not possible to obtain a soil test, the following soil amendments shall be made: Pulverized agricultural limestone at 100 lbs./1000 ft.2 (2 tons/acre). • NOTE: Only carbonage forms of lime may be used. Dolomitic lime- stone shall be used on the Coastal Plain. Fertilizer at 25 lbs./1000 q .2 (1000 lbs./acre) of 10-10-10 in fall, or 25 lbs./1000 ft. of 5-10-10 in spring. NOTE: Equiva- lent nutrients may be applied with other fertilizer formulations. These amendments shall be spread evenly over the area to be sodded, and incorporated into the top 3-6 inches of the soil by discing, harrowing or other acceptable means. 3. Prior to laying sod, the soil surface shall be clear of trash, debris, • roots, branches, stones and clods in excess of 2 inches in length or diameter. Sod shall not be applied to gravel or other non -soil surfaces. 4. Any irregularities in the soil surface resulting from topsoiling or other operations shall be filled or leveled in order to prevent the formation of depressions or water pockets. 5. Areas to be topsoiled and topsoil used shall fulfill the requirements of TOPSOILING, Std. & Spec. 1.61. No sod shall be spread on soil which has been treated with soil sterilants until enough time has elapsed to permit dissipation of toxic materials. • III-233 •:o 1.67 Quality of Sod 1. Sod used shall be state -certified or state -approved. Certified turf - grass sod is grown from Certified seed, inspected and certi'iea by the Virginia Crop Improvement Association or the certifying agency in other states. This insures genetic purity, high quality, freedom from noxious weeds and excessive insect or disease problems.

Use Table 1.67a to select the type of sod best suited to your area. Sod Installation (Plate 1.67a) 1. Sod should not be laid on soil surfaces that are frozen. 2. During periods of high temperature, the soil shall be lightly irri- gated immediately prior to laying the sod, to cool the soil and re- duce root burning and dieback. 3. The first row of sod shall be laid in a straight line with subsequent rows placed parallel to and butting tightly against each other. Lateral joints shall be staggered to promote more uniform growth and strength. Care shall be exercised to insure that sod is not • stretched or overlapped and that all joints are butted tight in order to prevent voids which would cause drying of the roots. 4. On slopes 3:1 or greater, or wherever erosion may be a problem, sod shall be laid with staggered joints and secured by pegging or other approved methods. Sod shall be installed with the length perpendicu- lar to the slope (on the contour). 5. As sodding of clearly defined areas is completed, sod shall be rolled or tamped to provide firm contact between roots and soil. 6. After rolling, sod shall be irrigated to a depth sufficient that the underside of the sod pad and the soil 4 inches below the sod is thoroughly wet. 7. During the first week, in the absence of adequate rainfall, watering shall be performed as often as necessary to maintain moist soil to • a depth of at least 4 inches. III-235 I ':/ 1.67 8. The first mowing shall not be attempted until the sod is firmly rooted, • usually 2-3 weeks. Not more than 1/3 of the grass leaf shall be removed at any one cutting.

Purposes 1. To reduce erosion and decrease sediment yield from disturbed areas. • 2. To stabilize disturbed areas with a specific plant material suited to the site which cannot be established by seed. 3. To establish vegetative cover more rapidly than would be possible using seed. Conditions Where Practice Applies 1. In hybrid bermudagrass is the desired plant material, and establishment with sod is not preferred. 2. Bermudagrass is particularly suited to droughty, sandy sites or sit- uations where high salt content is a problem. It should not be used in shaded areas or on poorly drained sites. 1..

Irrigation must be available during the establishment phase. • Planning Considerations Bermudagrasses are warm -season permanent grasses which are well suited to erosion control, as they have vigorous rhizomes and stolons (runners). There are two types of bermudagrass grown in Virginia, common and hybrid. Common bermudagrass produces seed and may be established with seed. However, it has the potential to become a weed problem because it spreads vigorously; it is also coarse and not suitable for fine turf. Common bermuda has little cold tolerance and winterkills frequently Hybrid bermudagrasses do not produce viable seed and must be established by sodding, sprigging, or plugging. These grasses produce a fine, tight turf, do not spread as vigorously as common bermudagrass, exhibit good cold tolerance, and can withstand many adverse conditions. For these reasons, hybrid bermudagrass is the warm -season permanent turf grass of choice for Virginia. • Turf may be established most rapidly and efficiently with sod. Where speed is essential and cost is not an overriding constraint, sod should be used. (See SODDING, Std. & Spec. 1.67). Sprigging: A bermudagrass sprig is a small section of rhizome (under- ground stem) 3 to 5 inches long, with at least one node or joint. Leaves should be present at the nodes. Stolons (runners) are above- ground stems that spread by creeping on the soil surface. A mixture of sprigs and stolons is usually used in •sprigging". Sprigs may be planted by machine or hand. Plugging: Plugs are small sections of sod which are pressed into precut holes in the soil so that topgrowth is flush to the surface and leaves are exposed. Plugs are usually planted by hand. Bermudagrass is particularly suited to use in grasslined waterways. • Depending upon the soil type, an established stand of bermudagrass can tolerate intermittent concentrated flows of water on slopes up to 10%. It is important to divert runoff from the waterway during the first three weeks of establishment to permit bermudagrass to take root. If this cannot be done, the center of the waterway should be sodded to prevent washout. Bermudagrass is drought -tolerant, salt -tolerant, and tolerates floods of short duration. It prefers a pH range from 6.0-7.0 with high nitrogen fertilization during the growing season. Most bermudagrasses are adapted only to Southeastern Virginia. All bermudagrasses will be dormant in winter and will turn brown at that time. • III-242 •SI The bermudagrass hybrids most frequently used in Virginia differ in appear- ance, cold tolerance, and suitability for turf use. The following varieties are suggested for rough and fine -turf areas: For Rough Areas Midland: A cold -hardy variety adapted in all areas of the state at medium to low elevations. Adapted for forage production, this is a tall -growing Bermuda (12-18 inches) and should be used in low -maintenance areas. Coastal: .lso a forage type, for low -maintenance areas. Can be used as far west and north as Chatham, Charlotte Courthouse, and Warsaw but will winterkill during severe winters at those locations. For Fine -turf Areas Midiron: A fine -turf type. Has a good chance of surviving most winters • as far west and north as Blacksburg and Charlottesville. Tufcote: A fine -turf type. Less cold -hardy than Midiron; use mostly south of Richmond. Tifway: A fine -textured turf type. Good survival east and south of Richmond in most years. Not as cold -hardy as Tufcote. Specifications Soil Preparation Procedures for preparing the soil are the same for sprigging and plug- ging. 1. Bermudagrass requires soil which is well drained, loose enough for • root penetration, has a pH range between 6.0-7.0, and is free of toxic amounts of materials harmful to plant growth. If any of these criteria cannot be met, topsoil shall be applied in accordance with TOPSOILING, Std. & Spec. 1.61. 2. Necessary erosion and sediment control practices will be installed prior to establishment of bermudagrass. Final grading will be carried out according to the approved plan. 3. Surfaces will be roughened in accordance with SURFACE ROUGHENING, Std. & Spec. 1.60. 4. The soil shall be free of debris, trash, roots, and weeds. Lime and Fertilizer Soil tests should be made to determine the exact requirements for lime • and fertilizer. Soil tests may be conducted by the State Laboratory at VPI & SU or a reputable commercial laboratory. Information on free state soil tests is available from county or city agricultural extension agents. III-243 •SI Under difficult circumstances where it is not possible to obtain a soil test, the following soil amendments shall be made: • Pulverized a ricultural limestone: 100 lbs./1,000 ft.2 (2 tons/acre). N Only carbonate' orms of may be used. Dolomotic limestone sha 1 be used on the Coastal Plain. Fertilizer: 500 lbs. 10-20-20/acre (12 lbs./1,000 ft. 2). NOTE: Equiva ent nutrients may be applied with other fertilizer formulations. These amendments shall be spread evenly over the area to be spriqged, and incorporated into the top 3-6 inches of the soil by discing, harrow- ing or other acceptable means. Any irregularities in the soil surface resulting from topsoiling or other operations shall be filled or leveled in order to prevent the formation of water pockets. Soil preparation, liming, and fertilizing should be completed before i delivery of sprigs or sod is requested. This material is perishable and should not remain on a pallet or in crates longer than 36 hours from the time of dig;4 The presence of mildew or distinct yellowing of the leaves is usually a good indication of damage to turf. SPRIGGING AND PLUGGING Sources Sprigs can be purchased as sod and then shredded or can often be purchased by the bushel. For turf -type bermudagrasses, Certified or Approved sod sources (bearing the label of the Virginia Crop Improvement Association) should be used. Coastal and Midland Bermudagrasses are available through agricultural sources. Contact the county or city agricultural extension agent or the Soil Conservation Service district office for information on where these materials may be obtained. Plugs may be cut from sod • as needed or purchased pre-cut. Sprigs shall be 3 to 5 inches long, having several nodes (joints). Plugs shall have a minimum diameter of 2 inches. Quantities of Material Needed Sprigging: 2-7 bushels per 1,000 ft.2, or 80-300 bus�els per acre. One bushel of sprigs is approximately equal to 1 yard of sod. Plugging: About 12 square yards of sod for 1,000 ft.2, or 530 square yards of sod for one acre. • III-244 19 - When -to Plant To establish quickly, bermudagrass should not be in a dormant state (leaves should be green). In order that plants may develop adequate root struc- ture before cold weather begins, plantings should be made no later than midsummer. May 1 through July 15 is the optimum season for bermudagrass establishment. How to Plant SPRIGGING: Sprigs may be broadcast over the surface by hand, planted in rows by machine, or applied with a hydroseeder. Machines are avail- able which will insert sprigs properly and firm the soil over them. When sprigs are broadcast or hydrosprigged, they should be partially covered with soil by light discing or topdressing with good soil. Ideally, half of the sprig should be covered with soil, and half (including some leaves) should be exposed. Soil should be firmed over the sprigs by • using a cultipacker, or by rolling or tamping. Spacing - When planted in rows, sprigs should be placed no more than 12 inches apart in rows 12 to 18 inches apart. Closer spacing is recommended for slopes, water- ways, and highly erodible soils. PLUGGING: Plugs should be inserted in the soil surface so that leaf tips are above the surrounding soil, and tamped firmly in place. Spacing - Plugs should be placed in a grid pattern on 12-18 inch centers. Closer spacing is recommended on critical areas. Plugs are usually placed by hand, but machines are available which can plug automatically. Weed Control In order to become effectively established, bermudagrass must not have to compete with weeds for sunlight, water, or space. Cultivating is impractical as growing stolons may be injured. Simazine, applied within one or two days after sprigs are planted, gives excellent control of most broadleaf and grassy weeds. Use 1 4/2 to 2 lbs. active ingredient per acre. For control of broadleaf weeds only, apply Dicamba (1/4 to 1/2 lbs. active ingredient/acre) and 2,4-D (1 lb. active ingredient/acre). Use when weeds are 2-3 inches tall, but not before grass is well -rooted. Maintenance Bermudagrass sprigs and plugs can be expected to root in 5 to 10 days under optimum conditions. Full coverage of -the soil by spreading plants can be effected in 4 to 8 weeks with good growing conditions. The following are essential for good bermudagrass growth: • 1. Adequate moisture.

Purposes 1. To prevent erosion by protecting the soil surface from raindrop im- pact and reducing the velocity of overland flow. 2. To foster the growth of vegetation by increasing available moisture and providing insulation against extreme heat and cold. Conditions Where Practice Applies 1. Areas which have been permanently seeded should be mulched immedi- ately following seeding. 2. Areas wh4rh rannnt be seeded because of the season should be mulched to provide some protection to the soil surface. An organic mulch (not wood fiber alone) shall be used, and the area then seeded as soon as feasible in spring. III-247 1980 1.751 3. Mulch shall be used together with plantings of trees, shrubs, or certain ground covers which do not provide adequate soil stabiliza- tion by themselves. 4. Mulch shall be used in conjunction with temporary seeding operations as specified in TEMPORARY SEEDING, Std. & Spec. 1.65. Planning Considerations Mulches are applied to the soil surface to conserve a desirable soil property or to promote plant growth. A surface mulch is one of the m^st effective means of controlling, runoff and erosion on disturbed land. Mulches can increase the infiltration rate of the soil, reduce soil mois- ture loss by evaporation, prevent crusting and sealing of the soil sur- face, modify soil temperatures, and provide a suitable microclimate for seed germination. Organic mulch materials, such as straw, wood chips, bark, and wood fiber, • have been found to be the most effective. Chemical soil stabilizers or soil binders are less effective mulches when used alone. T')ese m- terials are useful to bind organic mulches together. A variety of nets and mats have been developed for erosion control in recent years, and these are also used as mulches, pa�i:i�uiaiiy in cri- tical areas such as waterways. They may be used to hold other mulches to the soil surface. The choice of materials for mulching will be based on the type of soil to be protected, site conditions, season, and economics. It is especially important to mulch liberally in mid -summer and prior to winter, and on cut slopes and southern slope exposures. Organic Mulches 0 Straw - The mulch most commonly used in conjunction with seeding. The straw should come from wheat or oats, and may be spread by hand or machine. Straw can be windblown.and must be tacked down. Corn Stalks - These should be shredded into 4- to 6-inch lengths. Stalks decompose slowly and are resistant to windblow. Wood Chips - Suitable -for areas that will not be closely mowed, and around ornamental plantings. Chips decompose slowly, do not require tacking. Must be treated with 12 pounds nitrogen per ton to prevent nutrient defi- ciency in plants. Can be a very inexpensive mulch if chips are obtained from trees cleared on the site. Bark Chips, Shredded Bark - By-products of timber processing. Used in landscaped plantings. Bark is also a suitable mulch for areas planted 110 III-24US 1980 1.75 to grasses and not closely mowed; may be applied by hand or mechanically. • Bark is not usually toxic to grasses or legumes, and additional nitrogen fertilizer is not required. Wood Fiber - Used in hydroseeding operations, applied as part of the slurry. These short cellulose fibers do not require tacking, although tacking agent or soil binders are sometimes used with wood fiber. This form of mulch does not provide sufficient protection to erodible soils to be used alone during the severe heat of summer or for late fall seed- ings. Wood fiber hydroseeder slurries may be used to tack straw mulch. This combination treatment is well suited to steep slopes and critical areas, and severe climate cor_.'it-ions. There are other organic materials which make excellent mulches but are only available locally or seasonally. Creative use of these materials can reduce costs. Chemical Mulches and Soil Binders • 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, asphalt, rubber or other substances which are mixed with water and applied to the soil. They may be used alone or may be used to tack wood fiber hydromulches or straw. When used alone, chemical mulches do not have the capability to insulate the soil or retain soil moisture that organic mulches have. This soil protection is also damaged by traffic. Application of these mulches is usually more expensive than organic mulching, and the mulches decom- pose in 60-90 days. Nets and Mats Used alone, netting does not retain soil moisture or modify soil tempera- ture. It stabilizes the soil surface while grasses are being established, • and is useful in grassed waterways and on slopes. Light netting mail also be used to hold other mulches in place. • The most critical aspect of installing nets and mats is obtaining firm, continuous contact between the material and the soil. Without such con- tact, the material is useless and erosion occurs. It is important to use an adequate number of staples and to roll the material after laying it to insure that the soil is protected.

Table 1.75a 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 needeo sediment control practices. Lime and fertilizer should be incorporated and surface roughening accom- plished as needed. ^d should be applied prior to mulching except in the following cases: a.) Where seed is to be applied as part of a hydro - seeder slurry containing wood fiber mulch. b.) Where seed is to be ap- plied following a straw mulch spread during winter months. c.) Where a hydroseeder slurry is applied over straw. Application: Mulch materials shall be spread uniformly, by hand or machine. is When spreading straw mulch by hand, divide the area to be mulched into approximately 1,000 sq. ft. sections and place 70-90 lbs. (1-1/2 to 2 bales) of straw in each section to facilitate uniform distribution. Mulch Anchoring: Straw mulch must be anchored immediately after spread- ing to prevent windblow. Other organic mulches listed in Table 1.75a do not require anchoring. The following methods of anchoring straw may be used: 1. Mulch anchoring tool: This is a tractor -drawn implement designed to punch mulch into the soil surface. This method provides maximum 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. Liquid mulch binders: Application of liquid mulch binders and tacki- 40 should be heaviest at edges of areas and at crests of ridges and banks, to prevent windblow. 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. Applying straw and binder together is the most effective method. The following types of binders may be used: a. 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 emul- sified 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 ft.2, • 480 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. III-251 1980 1.75 b. Synthetic binders --Chemical binders such as Petroset, Terratack and Aerospray may be used as recommended by the manufacturer • to anchor mulch. These are expensive and therefore usually used in small areas or in residential areas where asphalt may be a problem. (Use of trade names does not constitute an endorsement by the Commission). 3. Mulch nettings--Lightweight plastic, cotton, or paper nets may be stapled over the mulch according to manufacturer's recommendations. (See NETS AND MATS, below). 4. P--. and twine --Because it is labor-intensive, this method is feasible on y 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 May 1 to June 15 and September 15 to October 15, 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. 1.60. If rill erosion occurs, another mulch material shall be applied immediately. Note: Chemical mulches may be used to bind other mulches or with , wood fiber in a hydroseeded slurry at any time. Manufacturer's recom- mendations for application of chemical mulches shall be followed. NETS AND MATS Nets may be used alone on level areas, on slopes no steeper than 3:1, - and in waterways (as specified in STORMWATER CONVEYANCE CHANNELS, Std. & Spec. 1.35). When mulching is done in late fall or during June, July and August, or where soil is highly erodible, net should only be used in conjunction with an organic mulch such as straw. When net and organic mulch are used together, the net should be installed over the mulch except when the mulch is wood fiber. Wood fiber may be sprayed on top of the installed net. III-252 1980 1.75 Excelsior blankets are considered protective mulches and may be used • alone on erodible soils and during all times of year. Materials: Jute net shall be heavy, uniform cloth woven of single jute yarn, which if 36 to 48 inches wide shall weigh an average of 1.2 pounds per linear yard. CJ Other products designed to control erosion shall conform to manufacturer's specification and shou d be app ied in accordance with manufacturer's instructions provided those instructions are at least as stringent as this specification. Examples of these products are Erosionet, Holdgro, Weedchek, and Cur ex. (Use of trade names does not indicate endorsement of products by the Commission.) In no case shall these products cover less than 30% of the soil surface. Staples will be made of plain iron wire, No. 8 gauge or heavier, and will be 6 inches or more in length. Prior to installation: 1. Shape and grade as required the waterway, channel, slope or other area to be protected. 2. Remove all rocks, clods, or debris larger than 2 inches in diameter that will prevent contact between the net and the soil surface. 3. When open -weave nets are used, lime, fertilizer and seed may be applied either before or after laying the net. When excelsior matting is used, they must be applied before the mat is laid. Laying the Net: (Plates 1.75a and 1.75b) 1. Start laying net from top of channel or top of slope and unroll down- grade. • 2. Allow to lay loosely on soil --do not stretch. 3. To secure net: Upslope ends of net should be buried in a slot or trench no less than 6 inches deep. Tamp earth firmly over net. Staple the net every 12 inches across the top end. • Edges of net shall be stapled every 3 feet. Where 2 strips of net are laid side by side, the adjacent edges shall,be overlapped 3 inches and stapled together. Staples shall be placed down the center of net strips at 3-foot intervals. DO NOT STRETCH net when applying staples. Joining strips: Insert new roll of net in trench, as with upslope ends of net. Overlap the end of the previous roll 18 inches, turn under 6 inches, and staple across end of roll just below anchor slot and at the end of the turned -under net every.12 inches. III-253 IyIbu Flow INSTALLATION OF NETTING AND MATTING Anchor Slot: Bury the up -channel end of the net in a 6' deep trench. Tamp the soil firmly. Staple at 12" intervals across the net. Overlap: Overlap edges of the strips at least 4". Staple every 3 feet down the center of the strip. ' Joining Strips: Insert the new roll of net in a trench, as with the Anchor Slot. Over- lap the up -channel end of the previous roll 18" and turn the end under 6". Staple the end of the previous roll just below the anchor slot and at the end at 12" intervals. Check Slots: On erodible soils or steep slopes, check slots should be made every 15 feet. Insert a fold of the net into a 6" trench and tamp firmly. Staple at 12" intervals across the net. Lay the net smoothly on the surface of the soil - do not stretch the net, and do not allow wrinkles. Anchoring Ends At Structures: Place the end of the net in a 6" slot on the up -channel side of the structure. - _ — Fill the trench and tamp firmly. Roll the net up the channel. Place staples at 12" intervals along the �7 anchor end of the net. Source: Adapted from Conwed Products Brochure Plate 1.75a • • • i III-254 M t 1.75 At bottom of slopes: Lead net out onto a level area before anchoring. Turn ens under inches, and staple across end every 12 inches. • Check slots: On highly erodible soils and on slopes steeper than 4:1, erosion check slots should be made every 15 feet. Insert a fold of net into a 6-inch trench and tamp firmly. Staple at 12-inch intervals across the downstream portion of the net. Rolling: After installation, stapling, and seeding, net should be rolled to insure firm contact between net and soil. MAintonanro All mulches should be inspected periodically, in particular after rain- storms, to check for rill erosion. Where erosion is observed, additional mulch should be applied. Net should be inspected after rainstorms for dislocation or failure. If washouts or breakage occur, re -install net as necessary after repairing damage to the slope. 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 deter-- -c- if m0 rh is maintaining coverage of the soil sur- face; repair as needed. • • III-256 INDEX ELECTRICAL Paragraph No. 1 General 2 Scope of Work 3 Electric Service Characteristics 4 Service Entrance Conductors 5 Raceways 6 Conductors• 7 Grounding 8 Pull Boxes 9 Outlet Boxes 10 Switches 11 Switch and Receptacle Plates 12 Receptacles 13 Panelboards 14 Motors 15 16 Combination Circuit Breaker Motor Starters Branch Circuits 17 Motor Control Centers 18 Lighting Fixtures 19 Final Tests 20 Interference and Erroneous Locations 21 Pump Control Panels Page No. 1 1 1 1 2 2 3 3 3 3 4 4 4 5 5 6 6 6 7 7 8 • DETAILED SPECIFICATIONS SECTION IX ELECTRICAL 1.

Box 443 Winchester, Va.2 2601 We are returning one set of the site plans for the Apple Pie Ridge Campus of James Wood High School. The plans appear to be satisfactory with the exception of the entrance location. The proposed location has a very short sight distance to the east and is not acceptable. We have shown in red on the plans, a possible location which would have adequate sight distance. We are reluctant to approve an entrance with less then six hundred feet (600') of sight distance in both directions. I will be glad to assist in any way possible in locating a safe entrance location.

The site plan should indicate that booster pumps will be needed to increase water pressure, and if possible the location of the booster station should be shown. The entrance roadway should be a minimwn of thirty (30) feet in width, and it should be level from the edge of pavement on Route 739 for a distance of fifty (50) feet and then the grade may increase. The proposed ten percent (10%) grade on the entrance roadway is not desirable and other locations should be explored to reduce the grade, but retaining the maxi -um possible sight -distance on Route 739. Would you please also provide me with the Vehicle trips per day anticipated for the main entrance. Individual parking •places must be shown in the parking area and the school bus loading area should be shown along with information on the maximum number of buses expected at any given time. The area north of the school site should be indicated as future athletic fields or whatever the future intended use may be. Thank you for meeting with me Monday. If. you have any questions concerning these requirements, please contact me. HRB: btr cc: J. 0. Renalds, III, Dr. Melton Wright Reginald C.

Ronald Berg RE: James Wood High School - Apple Pie Ridge Campus Frederick County, Virginia Site Plan Gentlemen: In response to your letter of April 3, 1978, we have ccmpiled the additional information requested and herewith offer it for your use: 1) On April 4, 1978, we supplied you with six (6) copies of this project's Preliminary Site Plan dated Rev.#1 4/3/78 which denotes the following: a) Possible location of booster pump station. b) The number of parking spaces planned for each parking area, c) Proposed future use of area north of the building structure. 2) A thirty (30) foot wide entrance from Route 739 to the property line, and a fifty (50) foot long level landing at the intersection of the entrance and Route 739 will be implemented on the final site plan. 3) The anticipated vehicle trips per day for the main entrance are two thousand (2000). 4) The bus loading area is shown as that section of the school's roadway system bounded by the building structure and the student parking lot including the circle. The maximum number of buses expected at any given time in the bus loading area is twelve (12). Member Associated General Contractors of America ' HOWARD $HOCKEY & SONS, INC. Frederick County Director of Planning April 10, 1978 Page 2 5) On Friday, April 7, 1978, representatives of the Commonwealth of Virginia Department of Highways and Transportation inspected the building site in order to determine the most feasible location for the main entrance along Route 739. Their conclusion was that the most feasible location for the entrance was that as already illustrated on the site plans. Since the Highway Department concurs with our location of the main entrance and the building elevation has been set based on site topography, the grade of the entrance roadway remains unchanged from that indicated on the drawings. It is our hope that this information is sufficient to allow the project to be placed before the Frederick County Planning Commission at its next regularly scheduled meeting (April 19, 1978), and request that you enlighten us to this possibility.

B. COLDIRON DIRECTOR OF ENGINEERING H. R. PERKINSON, JR. DIRECTOR OF PROGRAM MANAGEMENT IN REPLY PLEASE REFER TO Edinburg, VA 22824 April 12, 1978 I have received a copy of Mr. W'. ft. Thomas Jr.'s letter of April 10, 1978, and Bill is correct as far as he goes in item 5. The proposed entrance is the only feasible location from an economic and grading point of view into this extremely hilly site. Even at this proposed entrance, there is a problem with sight distance to the east (to the left of a driver exiting from the proposed entrance) on Rt. 739. _A large depression or dip in Rt. 739 will have to be filled in, thereby raising the road several feet for a distance of approximate- ly four hundred feet. This must be done to provide adequate sight dis- tance coming out of the school entrance. I am certain that this work must be done at the School Board's (County) expense. The reasoning is that this section of Rt. 739 is entirely adequate and satisfactory at the present time, but the new school entrance will create an unsafe condition. Therefore, it is up to the party creating the condition to alleviate it. Dr. Wright does not agree with the thought that the School Board is re- sponsible for this work and has sent in a letter asking the Department of Highways and Transportation to absorb the cost. 1 have forwarded his request on through channels and will respond when I receive a reply. In summary, we have approved the proposed entrance contingent upon the necessary improvements being made to Rt. 739. Very truly yours, ohn W. Chiles, Jr. Resident Engineer cc - Mr. W. F.

Ronald Berg RE: James Wood High School - Apple Pie Ridge Campus Frederick County, Virginia Considered Entrance Road Locations Gentlemen: In response to your verbal request of April 13, 1978, that we expand upon item number five (#5) of our transmittal of April 10, 1978, to relate the alternate entrance locations considered and why they were deemed undesirable, we offer the following: 1) An entrance immediately off of Route 522 would have a grade in excess of ten percent (10%). 2) An entrance off of Route 739 immediately north of the Apple Pie Ridge Elementary School would separate that school from its outdoor activity area and pose a hazard to that school's population. 3) An entrance off of Route 739 utilizing the existing 60' right of way on the north property line would not improve upon the ten percent (10%) grade. 4) An entrance off of Route 739 south of the Apple Pie Ridge Elementary School would be in an existing horizontal curve on Route 739. With reference to item number five (#5) of our transmittal of April 10, 1978, we would like to reiterate that representatives of the Commonwealth of Virginia Department of Highways and Transportation did consider all of the aforementioned locations and came to the conclusion that the most feasible location for the entrance is that as already illustrated on the site plans.
