Atotal of approximately 2.8 acres will be disturbed during construction. EXISTING SITE CONDITIONS The topographic and built improvements existing on the subject property are depicted on the accompanying E&S plan, utility plan & profiles, and the general notes sheet. ADJACENT AREAS A majority of the site lays adjacent to the existing University Village properties. The site boundary to the north, east and south will be subdivided from the existing University Village open space that was designated for future development on the approved Master Plan. The boundary to the west abuts Huntington Village. The site can be accessed via Crestwood Drive, which connects the site to Old Ivy Road. OFF-SITE AREAS All land disturbing activities shall occur on-site and within the limits of project shown on the plans. At this point, no off-site borrow, waste or grading activity will occur. SOILS This site is located in a geologic area referred to as the Piedmont Physiographic Province. The soils in this geologic area are weathered from the underlying metamorphic bedrock. The naturally occurring soils at this site were found to be moderately to highly plastic silts weathered from the Catoctin formation which consists of basic lava flows, schist, and gneiss composed of chlorite, plagioclase, amphiobole, and epidote. The soils observed here appear to be weathered from metamorphosed sedimentary soils such as phyllite and schist. The map units on the detailed soil map depicted on the Erosion and Sediment Control Plan, represent the soils in the survey area. The map unit descriptions, along with the soil maps, can be used to determine the suitability and potential of a soil for specific uses, and, precautionary erosion and sedimentation control measures which must be adhered to. They also can be used to plan for the management needed for those uses. The profile of the soil classifications follows: Albemarle Fine Sandy Loam (2C): This deep, strongly sloping (7-15 / ), well drained soil is on convex ridgetops and side slopws. Typically, the surface layer is very dark grayish brown and brownish yellow fine sandy loam about five (5) inches thick. The subsoil is about twenty-five (25) inches thick strong brown and yellowish red clay loam. The substratum is mostly yellowish brown, gray, and yellow sandy loam. Bedrock is at a depth of about fifty (50) inches. Permeability and available water capacity is moderate. Runoff is rapid, and the hazard of erosion is severe. The subsoil has low shrink -swell potential. Bedrock is generally at a depth of,forty (40) to sixty (60) inches. Culpepper Fine Sandy Loam (2113): This deep, gently sloping (2-7%), well drained soil is on narrow to broad convex ridge tops. Typically, the surface layer of this soil is brown and yellowish brown fine sandy loam about six (6) inches thick. The subsoil is yellowish red clay loam and red clay and sandy cllay loam about twenty-nine (29) inches thick.. The substratum is reddish yellow fine sarndy loam. Permeability and available water capacity are moderate. Runoff is mediumi. The hazard of erosion is moderate. The subsoil has moderate shrink -swell potential: Bedrock is generally at a depth of fifty (50) inches or more. Culpepper Fine Sandy Loam (21 C): This deep, strongly sloping (7-15%), well drained soil is on narrow, convex ridge tops and on shoart side slopes. Typically, the surface layer is brown and yellowish brown fine sandy loiam about eight (8) inches thick. The subsoil is yellowish red clay loam and red clay and sandy clay loam about twenty-nine (29) inches thick. The substratum is reddish yellow fine sandy loam. Permeability and available water capacity are moderate. Shrink -swell potential is moderate. Runoff is rapid, and the hazard of erosion is severe. Bedreock is generally at a depth of fifty (50) inches or more. CRITICAL AREAS There are several critical areas on the site. These, include several areas of steep slopes greater than 4:1. The steep slopes are generally) the result of previous land disturbing activities related to thee' existing building and were i 9 e m acted only where 9 p y they could not be avoided. EROSION AND SEDIMENT CONTROL MEASURES The. contractor shall provide, construct and maintain erosion and sediment control measures on the site, in accordance with the Virgiinia Department of Transportation and the County of Albemarle erosion and sediment ciontrol measures (refer to the Erosion and Sediment Control Plan sheet). All vegetative, and structural erosion and sediment control practices shall be constructed and maintaiined according to minimum standards and specifications of the Virginia Erosion and Sediiment Control Handbook. Permanent or temporary soil stabilization shall Ibe applied to denuded areas within seven (7) days after final grade is reached on amy portion of the site. Temporary soil stabilization shall be applied within seven (7) days,, to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. Soil stabilization refers to measures that protect soil from the erosive forces of raindrop impact and flowing g water. Applicable practices include vegetative establishment, mulching, and the early application of gravel base on areas to be stone. Soil stabilization measures should t)a selected to be appropriate for the time of the year, site conditions, and estimated duration of use. Temporary sediment filters and traps, perimeter dikes, sediment barriers and other measures intended to retain sediment shall be cornstructed as a first step in any land - disturbing activity and be made functional before up slope land disturbance takes place. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. The following structural practices will be implementced according to the requirements set forth by the Virginia Erosion and Sediment Control. Safety Fence (3.01) A protective barrier consisting of polyethylene web :secured to a conventional metal post driven into the ground a minimum of 18 inches. Posts should be spaced at 6 -foot centers. Used to prevent undesirable use of an ercosion control measure by the public. To prevent access to an erosion control measure. Specific Application: Safety fence will be used at areas where residents and staff of University Village may come into contact with the planned work. 1. Paved Wash rack Construction Entrance (3.02) A seventy (70) foot paved section shall be installed at the point of vehicular ingress and from vehicles exiting the site. Where sediment is transported onto a public road egress on the construction site. This paved area cshall be used for washing sediment surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping arnd transported to a sediment control. disposal area. Street washing shall be allowed onlly after sediment is removed in this manner. This provision shall apply to individual subdivision lots as well as larger land disturbing activities. Specific Application: A construction entrance shall be placed adjacent to the existing road at the east end of the site. cc. Construction Road Stabilization (3.03 Temporary stabilization with stone of access roads„ subdivision streets, parking areas and other traffic areas immediately after grading to reduce erosion caused by vehicles during wet weather, and to prevent having to regrrade permanent roadbeds between initial grading and final stabilization. Specific Application: Construction road stabilization :shall be applied to the travel ways, which require stabilization after prelimineary and fine grading. d� Silt Fence (3.05) A temporary sediment barrier consisting of synthetiac filter fabric stretched across and attached to supporting posts and entrenched. Usecd to prevent sediment from leaving the site. To decrease the velocity of sheet flows. Specific Application: Silt fence will be used at 'rhe fMt of the cut / fill slopes. ee . Inlet Protection (3.07) A temporary sediment filter around a storm inlet or curb inlet, in order to prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. Speciflc Application: Inlet protection will be used around all storm drainage inlets and curb inlets. D. Temporary Diversion Dike (&09) A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area. Used to divert sediment -laden runoff from a disturbed area to a stabilized outlet. S ecific Application: Diversion Dikes will be used to divert runoff away from the a'rstur5e areas construction. gh Temporary Sediment Trap (3.13) A temporary ponding area formed by constructing an earthen embankment with a stone outlet. It is used to detain sediment -laden runoff from drainage areas less than three acres for enough time to allow most of the sediment solids to settle out. It can be constructed only where there is sufficient space and appropriate topography. Maximum effective life is 18 months. Specific Application: Sediment traps will be used to detain runoff on the site at the foot of the fill and cut slopes. hi Surface Roughening (3.29) This erosion and sedimentation control measure involves creating horizontal depressions on slopes or leaving slopes in a roughened condition by not fine -grading them. This is done to aid in the establishment of vegetative cover or seed, to reduce runoff velocity and increase infiltration, and to reduce erosion and provide for sediment trapping. Specific Application: This form of protection shall be performed on all slopes 3:1 or greater as shown on the accompanying E&S Plan. Slopes less steep than 3:1 should have the soil lightly roughened and loose to a depth of 24" prior to seeding. 11 Temporary Seeding (3,31) The establishment of a temporary vegetative cover on disturbed areas by seeding with appropriate rapidly growing annual plants. This protects slopes exposed during construction until permanent vegetative cover can be established. Temporary seeding will apply to all areas on the site that will not be brought to final grade for periods of thirty (30) days to one year: Selection of the appropriate seed mixture depends upon the time of year it is to be applied (See schedule on E&S details sheet.) S2ecific Application: Temporary seeding shall be applied to all denuded areas prior to permanent stabilization in the form of either hardscape or permanent seeding. Temporary seeding shall be used on all fill slopes and diversions. jZ Permanent Seeding (3.32) Establishment of perennial vegetative cover by planting seed on rough -graded areas that will not be brought to final grade for a year or more or where permanent, long-lived vegetative cover is needed on fine -graded areas. _Specific Application: Permanent seeding will be applied to all portions of disturbed area. k.S � _oil stabilization Blankets & Matting (3,36) Stabilizing disturbed areas of a steep slope, channel, or a shoreline by applying protective covering on a prepared area. The matting will protect the young vegetation and promote its establishment while increasing the permissible velocity of turf grass stands. Specific Application: Where the proposed surface drainage is concentrated in ditch7ines. 1 Tree Protection Q.38) Protection of desirable trees from mechanical and other injury during land disturbing and construction activity. Specific Application: Tree protection shall be applied along vegetation line on the fringe of the site and to specific large trees. that are not to be disturbed. Dust Control (3.39) Reducing surface air movement of dust during land disturbances, demolition or construction activities in areas subject to dust problems in order to prevent soil loss and reduce the presence of potentially harmful airborne substance. Specific Application: Dust control shall be applied as necessary if time requires. PERMANENT STABILIZATION All areas disturbed by construction will be stabilized with permanent seeding immediately following finish grading. All seeds will be approved by the "Virginia Crop Improvement Association," Blacksburg Virginia. Seeding'will be done with the following: Two (2) parts Kentucky Bluegrass (Poa pratensis), by weight; minimum 98% purity and 90% germination; maximum 1% weed seed. Three (3) parts perennial Ryegrass (Labium perrene) by weight; minimum 85% purity and 90% germination; maximum 1% weed seed. Fifteen (15) parts Falcon Fescue; minimum 98% purity and 90% germination; maximum I% weed seed, Permanently seeded areas shall be protected during establishment. Mulch shall consist of oat or wheat straw, free from weeds, foreign matter detrimental to plant life, and dry. Hay or chopped cornstalks will not be permitted. Mulch and/or lime shall be applied at a rate of two (2) tons per acre. Specifications for fertilizer are FS 0 -F -241C, Type 1, solid form; Grade A or B; recommended for grass, with one hundred (100) percent of the elements derived from organic sources of the following properties: a) Nitrogen 12.0% b) Phosphoric Acid 8.0% C) Soluble Potash 8.0% With at least fifty (50) percent of the nitrogen from a non -water soluble organic source. The following measures shall be incorporated during fertilization: Apply fertilizer at a rate of 1000 lbs./acre. Apply after smooth raking of topsoil. Do not apply fertilizer at same time or with same machine as will be used to apply seed. Till fertilizer into upper two (2) inches of topsoil. Lightly water dry topsoil to depth of six (6) inches at least forty-eight (48) hours prior to seeding to obtain a loose friable seed bed and to aid in the dissipation of fertilizer. The following rates and practices will be adhered to for all seeding that occurs on-site: Apply seed a rate of 6-lbs./1000 sq. ft. evenly at right angles with a spreader or seeding machine. Rake in lightly, covering seed to depth of 1/8 inch. Do not seed area in excess of that which can be mulched on same day. Do not sow immediately following rain, when ground is too dry, or during windy periods. Roll seeded area with roller not exceeding 112 lbs. Immediately following seeding and compacting apply mulch to a thickness of one (1) inch. Maintain clear ofshrubs and trees. Apply water with a fine spray immediately after each area has been mulched. Saturate to six (6) inches of soil. MAINTENANCE All erosion and sediment control measures must be maintained and repaired immediately to insure continued performance of their intended functions as stated in the Virginia Erosion & Sediment Control Handbook, Third Edition 1992. In general, all erosion and sediment control measures will be checked weekly and after each runoff - producing rainfall event. All seeded and sodded areas will be checked regularly to ensure that a good stand is maintained. Areas will be fertilized, reseeded and resodded as needed. Sediment basins and/or traps shall be cleaned and maintained in accordance with the VA E&SC Handbook. All gravel outlets will be checked regularly for sediment buildup that will prevent proper drainage. If the gravel is clogged by sediment, the gravel will be removed and cleaned, or it will be replaced. DISPOSITION OF TEMPORARY MEASURES All temporary erosion and sediment control measures, including the temporary sediment basins, shall be removed within 30 days after final site stabilization is achieved or after the temporary measures are no longer needed, unless otherwise authorized by the local Program administrator. Trapped sediment and other disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sedimentation. STORMWATER MANAGEMENT Where applicable, silt fence and seeding will be capable of separating suspended solids from the runoff before it enters the existing natural channels. The west portion of the site will be treated by a sediment trap that will be converted to a biofilter at the conclusion of the project. The biofilter will provide treatment for the majority of storm events. Check dams located in the spillway channel will secondarily treat large storm events that overtop the biofilter. The runoff from proposed storm drains on the east side of the site will be treated by precast "Filterra" storm structures. Utilizing outlet protection in the form of riprap will dissipate the increase the velocity of the runoff from outflow devices during large storm events. Erosion control stone placed at the end of these outfalls will protect the channels and decrease the flow velocity. •0 B THE COX COMPANY Planners - Landscape Architects Civil Engineers o Urban Designers 220 East High Street Chaflottesville a Virginia 22902 , f434) 295.7131 Job Number. 03-740 Developer: MD Development, LLC One Boar's Head Pointe Charlottesville, VA 22903 P: 434.972.7764 F: 434.295.3203 Architect: Mitchell/Matthews P.O.

Atotal of approximately 2.8 acres will be disturbed during construction. EXISTING SITE CONDITIONS The topographic and built improvements existing on the subject property are depicted on the accompanying E&S plan, utility plan & profiles, and the general notes sheet. ADJACENT AREAS A majority of the site lays adjacent to the existing University Village properties. The site boundary to the north, east and south will be subdivided from the existing University Village open space that was designated for future development on the approved Master Plan. The boundary to the west abuts Huntington Village. The site can be accessed via Crestwood Drive, which connects the site to Old Ivy Road. OFF-SITE AREAS All land disturbing activities shall occur on-site and within the limits of project shown on the plans. At this point, no off-site borrow, waste or grading activity will occur. SOILS This site is located in a geologic area referred to as the Piedmont Physiographic Province. The soils in this geologic area are weathered from the underlying metamorphic bedrock. The naturally occurring soils at this site were found to be moderately to highly plastic silts weathered from the Catoctin formation which consists of basic lava flows, schist, and gneiss composed of chlorite, plagioclase, amphiobole, and epidote. The soils observed here appear to be weathered from metamorphosed sedimentary soils such as phyllite and schist. The map units on the detailed soil map depicted on the Erosion and Sediment Control Plan, represent the soils in the survey area. The map unit descriptions, along with the soil maps, can be used to determine the suitability and potential of a soil for specific uses, and, precautionary erosion and sedimentation control measures which must be adhered to. They also can be used to plan for the management needed for those uses. The profile of the soil classifications follows: Albemarle Fine Sandy Loam (2C): This deep, strongly sloping (7-15 / ), well drained soil is on convex ridgetops and side slopws. Typically, the surface layer is very dark grayish brown and brownish yellow fine sandy loam about five (5) inches thick. The subsoil is about twenty-five (25) inches thick strong brown and yellowish red clay loam. The substratum is mostly yellowish brown, gray, and yellow sandy loam. Bedrock is at a depth of about fifty (50) inches. Permeability and available water capacity is moderate. Runoff is rapid, and the hazard of erosion is severe. The subsoil has low shrink -swell potential. Bedrock is generally at a depth of,forty (40) to sixty (60) inches. Culpepper Fine Sandy Loam (2113): This deep, gently sloping (2-7%), well drained soil is on narrow to broad convex ridge tops. Typically, the surface layer of this soil is brown and yellowish brown fine sandy loam about six (6) inches thick. The subsoil is yellowish red clay loam and red clay and sandy cllay loam about twenty-nine (29) inches thick.. The substratum is reddish yellow fine sarndy loam. Permeability and available water capacity are moderate. Runoff is mediumi. The hazard of erosion is moderate. The subsoil has moderate shrink -swell potential: Bedrock is generally at a depth of fifty (50) inches or more. Culpepper Fine Sandy Loam (21 C): This deep, strongly sloping (7-15%), well drained soil is on narrow, convex ridge tops and on shoart side slopes. Typically, the surface layer is brown and yellowish brown fine sandy loiam about eight (8) inches thick. The subsoil is yellowish red clay loam and red clay and sandy clay loam about twenty-nine (29) inches thick. The substratum is reddish yellow fine sandy loam. Permeability and available water capacity are moderate. Shrink -swell potential is moderate. Runoff is rapid, and the hazard of erosion is severe. Bedreock is generally at a depth of fifty (50) inches or more. CRITICAL AREAS There are several critical areas on the site. These, include several areas of steep slopes greater than 4:1. The steep slopes are generally) the result of previous land disturbing activities related to thee' existing building and were i 9 e m acted only where 9 p y they could not be avoided. EROSION AND SEDIMENT CONTROL MEASURES The. contractor shall provide, construct and maintain erosion and sediment control measures on the site, in accordance with the Virgiinia Department of Transportation and the County of Albemarle erosion and sediment ciontrol measures (refer to the Erosion and Sediment Control Plan sheet). All vegetative, and structural erosion and sediment control practices shall be constructed and maintaiined according to minimum standards and specifications of the Virginia Erosion and Sediiment Control Handbook. Permanent or temporary soil stabilization shall Ibe applied to denuded areas within seven (7) days after final grade is reached on amy portion of the site. Temporary soil stabilization shall be applied within seven (7) days,, to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left dormant for more than one year. Soil stabilization refers to measures that protect soil from the erosive forces of raindrop impact and flowing g water. Applicable practices include vegetative establishment, mulching, and the early application of gravel base on areas to be stone. Soil stabilization measures should t)a selected to be appropriate for the time of the year, site conditions, and estimated duration of use. Temporary sediment filters and traps, perimeter dikes, sediment barriers and other measures intended to retain sediment shall be cornstructed as a first step in any land - disturbing activity and be made functional before up slope land disturbance takes place. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. The following structural practices will be implementced according to the requirements set forth by the Virginia Erosion and Sediment Control. Safety Fence (3.01) A protective barrier consisting of polyethylene web :secured to a conventional metal post driven into the ground a minimum of 18 inches. Posts should be spaced at 6 -foot centers. Used to prevent undesirable use of an ercosion control measure by the public. To prevent access to an erosion control measure. Specific Application: Safety fence will be used at areas where residents and staff of University Village may come into contact with the planned work. 1. Paved Wash rack Construction Entrance (3.02) A seventy (70) foot paved section shall be installed at the point of vehicular ingress and from vehicles exiting the site. Where sediment is transported onto a public road egress on the construction site. This paved area cshall be used for washing sediment surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping arnd transported to a sediment control. disposal area. Street washing shall be allowed onlly after sediment is removed in this manner. This provision shall apply to individual subdivision lots as well as larger land disturbing activities. Specific Application: A construction entrance shall be placed adjacent to the existing road at the east end of the site. cc. Construction Road Stabilization (3.03 Temporary stabilization with stone of access roads„ subdivision streets, parking areas and other traffic areas immediately after grading to reduce erosion caused by vehicles during wet weather, and to prevent having to regrrade permanent roadbeds between initial grading and final stabilization. Specific Application: Construction road stabilization :shall be applied to the travel ways, which require stabilization after prelimineary and fine grading. d� Silt Fence (3.05) A temporary sediment barrier consisting of synthetiac filter fabric stretched across and attached to supporting posts and entrenched. Usecd to prevent sediment from leaving the site. To decrease the velocity of sheet flows. Specific Application: Silt fence will be used at 'rhe fMt of the cut / fill slopes. ee . Inlet Protection (3.07) A temporary sediment filter around a storm inlet or curb inlet, in order to prevent sediment from entering storm drainage systems prior to permanent stabilization of the disturbed area. Speciflc Application: Inlet protection will be used around all storm drainage inlets and curb inlets. D. Temporary Diversion Dike (&09) A temporary ridge of compacted soil constructed at the top or base of a sloping disturbed area. Used to divert sediment -laden runoff from a disturbed area to a stabilized outlet. S ecific Application: Diversion Dikes will be used to divert runoff away from the a'rstur5e areas construction. gh Temporary Sediment Trap (3.13) A temporary ponding area formed by constructing an earthen embankment with a stone outlet. It is used to detain sediment -laden runoff from drainage areas less than three acres for enough time to allow most of the sediment solids to settle out. It can be constructed only where there is sufficient space and appropriate topography. Maximum effective life is 18 months. Specific Application: Sediment traps will be used to detain runoff on the site at the foot of the fill and cut slopes. hi Surface Roughening (3.29) This erosion and sedimentation control measure involves creating horizontal depressions on slopes or leaving slopes in a roughened condition by not fine -grading them. This is done to aid in the establishment of vegetative cover or seed, to reduce runoff velocity and increase infiltration, and to reduce erosion and provide for sediment trapping. Specific Application: This form of protection shall be performed on all slopes 3:1 or greater as shown on the accompanying E&S Plan. Slopes less steep than 3:1 should have the soil lightly roughened and loose to a depth of 24" prior to seeding. 11 Temporary Seeding (3,31) The establishment of a temporary vegetative cover on disturbed areas by seeding with appropriate rapidly growing annual plants. This protects slopes exposed during construction until permanent vegetative cover can be established. Temporary seeding will apply to all areas on the site that will not be brought to final grade for periods of thirty (30) days to one year: Selection of the appropriate seed mixture depends upon the time of year it is to be applied (See schedule on E&S details sheet.) S2ecific Application: Temporary seeding shall be applied to all denuded areas prior to permanent stabilization in the form of either hardscape or permanent seeding. Temporary seeding shall be used on all fill slopes and diversions. jZ Permanent Seeding (3.32) Establishment of perennial vegetative cover by planting seed on rough -graded areas that will not be brought to final grade for a year or more or where permanent, long-lived vegetative cover is needed on fine -graded areas. _Specific Application: Permanent seeding will be applied to all portions of disturbed area. k.S � _oil stabilization Blankets & Matting (3,36) Stabilizing disturbed areas of a steep slope, channel, or a shoreline by applying protective covering on a prepared area. The matting will protect the young vegetation and promote its establishment while increasing the permissible velocity of turf grass stands. Specific Application: Where the proposed surface drainage is concentrated in ditch7ines. 1 Tree Protection Q.38) Protection of desirable trees from mechanical and other injury during land disturbing and construction activity. Specific Application: Tree protection shall be applied along vegetation line on the fringe of the site and to specific large trees. that are not to be disturbed. Dust Control (3.39) Reducing surface air movement of dust during land disturbances, demolition or construction activities in areas subject to dust problems in order to prevent soil loss and reduce the presence of potentially harmful airborne substance. Specific Application: Dust control shall be applied as necessary if time requires. PERMANENT STABILIZATION All areas disturbed by construction will be stabilized with permanent seeding immediately following finish grading. All seeds will be approved by the "Virginia Crop Improvement Association," Blacksburg Virginia. Seeding'will be done with the following: Two (2) parts Kentucky Bluegrass (Poa pratensis), by weight; minimum 98% purity and 90% germination; maximum 1% weed seed. Three (3) parts perennial Ryegrass (Labium perrene) by weight; minimum 85% purity and 90% germination; maximum 1% weed seed. Fifteen (15) parts Falcon Fescue; minimum 98% purity and 90% germination; maximum I% weed seed, Permanently seeded areas shall be protected during establishment. Mulch shall consist of oat or wheat straw, free from weeds, foreign matter detrimental to plant life, and dry. Hay or chopped cornstalks will not be permitted. Mulch and/or lime shall be applied at a rate of two (2) tons per acre. Specifications for fertilizer are FS 0 -F -241C, Type 1, solid form; Grade A or B; recommended for grass, with one hundred (100) percent of the elements derived from organic sources of the following properties: a) Nitrogen 12.0% b) Phosphoric Acid 8.0% C) Soluble Potash 8.0% With at least fifty (50) percent of the nitrogen from a non -water soluble organic source. The following measures shall be incorporated during fertilization: Apply fertilizer at a rate of 1000 lbs./acre. Apply after smooth raking of topsoil. Do not apply fertilizer at same time or with same machine as will be used to apply seed. Till fertilizer into upper two (2) inches of topsoil. Lightly water dry topsoil to depth of six (6) inches at least forty-eight (48) hours prior to seeding to obtain a loose friable seed bed and to aid in the dissipation of fertilizer.
