3 INTRODUCTION AND PURPOSE The attached Erosion and Sediment Pollution Control Plan is for the Clover Mill Road Bridge Replacement. The bridge carries S.R. 1026, Section C01 over Pickering Creek. The project is located in West Pikeland Township, Chester County. This structure is being replaced due to the substandard condition of the existing bridge, which has a posted weight limit of 17 tons (24 tons combination). The existing structure is a two-span steel plate girder bridge, with each span having a clear span of approximately This structure, which includes a wooden deck with asphalt overlay and stone abutments, is currently in poor structural condition. The bridge exhibits various geometric and safety issues that do not meet current regulations and is currently posted for a 17-ton (24-ton combination) weight limit. In addition, the approach roadways are substandard with a steep vertical approach north of the bridge, which does not meet current design standards. Therefore, the decision was made to perform a full structure replacement, which considered various roadway profiles. Various requirements such as roadway design, right-of-way impacts, structure costs and hydraulic design were all considered and weighed to determine the most appropriate structure replacement with the least amount of impacts. Various preliminary structural designs and hydraulic runs were performed to narrow the list of potential structures. After review of the advantages and disadvantages of each alternative, it was determined that the single span prestressed adjacent box beam bridge should be the recommended alternative for this bridge replacement. Preliminary discussions with DEP and the District have verified that these slight increases in flood flow water surfaces associated with this option will not be significant enough to prevent approval nor should it trigger additional design work in the preparation of a conditional letter of map revision (CLOMR). The purpose of the Erosion and Sedimentation Control design is to minimize the volume of sediment leaving the construction area via stormwater runoff while maintaining the structural integrity of all disturbed and undisturbed soil areas within the subject property boundary. Supporting narrative, calculations and details are contained herein and on the Erosion and Sedimentation Control Plan (Plan). PLAN PREPARATION AND DEVELOPMENT The Erosion and Sedimentation Control Plan has been prepared by Traffic Planning and Design, Inc, 2500 East High Street, Suite 650, Pottstown, PA The Plan has been developed in accordance with the requirements and suggestions as outlined by the Pennsylvania Department of Environmental Protection (DEP), PENNDOT, and other acceptable engineering standards and practices. 1

4 SOIL CLASSIFICATIONS AND LIMITATIONS The Chester County Area Soil Survey prepared by the United States Department of Agriculture identifies five (5) types of underlying soils as Glenelg channery silt loam (3%-8% slopes, moderately eroded), Glenelg channery silt loam (8%-15% slopes, severely eroded), Glenville silt loam (3%-8% slopes, moderately eroded), Wehadkee silt loam, Worsham silt loam (0%-3% slopes). The descriptions and engineering properties of these soils can be found in the following table. TABLE 1: DESCRIPTION OF SOILS Glenelg channery silt loam, 3%-8% slopes, moderately eroded (GeB2) Glenelg channery silt loam, 8%-15% slopes, severely eroded (GeC3) Glenville silt loam, 3%-8% slopes, moderately eroded (GnB2) Wehadkee silt loam (We) Worsham silt loam, 0%-3% slopes (WoA) Typically these soils range from 18 to 34 inches in depth, but they are predominantly 20 to 30 inches deep. Their subsoil ranges from silt loam to silty clay loam in texture and from yellowish brown to reddish brown in color. Typically these soils range from 18 to 34 inches in depth, but they are predominantly 20 to 30 inches deep. Their subsoil ranges from silt loam to silty clay loam in texture and from yellowish brown to reddish brown in color. Typically the surface layer is very dark brown or dark grayish brown. The subsoil is yellowish brown or strongbrown, mottled silty clay loam or heavy silt loam. In a few places the texture of the subsoil is silty clay laom throughout the profile. Depth to bedrock ranges from 3 to 6 feet. Mottling is at a depth ranging from 15 to 30 inches. In some places there is a weak claypan in the subsoil. The dominant parent materials are mica schist and gneiss, but a few areas are underlain by granite. In these areas the texture of the subsoil is generally more clayey than that in the typical profile. The surface layer is dark grayish-brown silt loam. The subsoil is yellowish-brown silty clay loam that is mottled with various shades of grey. In most places stratified layers of sand and silt occur in these soils. The texture of the different horizons ranges from sandy loam to silty clay loam. The thickness and arrangement of the layers vary with the frequency of overflow from the streams and the kind of sediments deposited. Mottling is at or near the surface. The surface layer is generally silt loam, but if a few areas is silty clay loam. The subsoil ranges from silty clay loam to clay loam in texture. Depth of bedrock ranges from 5 to 10 feet. The surface layer in some place is thicker than normal because colluvial materials have been washed onto areas from adjacent higher areas. 2

7 ACCELERATED EROSION CONTROL MEASURES A combination of erosion control measures will be implemented during and after construction to stabilize or prevent advanced erosion from critical areas. Temporary vegetation shall be established on all slopes, on stockpiled topsoil, and on all disturbed areas. Disturbed areas are to be stabilized immediately. Course aggregate subbase material will be placed on all proposed roadways and parking areas, as soon as practical, in order to reduce erosion and soil disturbance associated with construction traffic. During construction, the amount of disturbed soils shall be kept to a minimum and, whenever possible, a suitable vegetative buffer will be maintained around all construction areas. SEDIMENTATION CONTROL Several measures will be used to remove sediment from stormwater leaving the construction site. Silt barrier fence will be installed down slope of all excavated areas in order to prevent sediment laden stormwater from entering local waterways, adjacent properties and roadways. Seeding and supplements along with straw mulch will be placed on the roadway embankment side slopes to prevent erosion. A stabilized construction entrance shall be properly maintained in order to prevent the migration of fines through the aggregate. TEMPORARY CONTROL MEASURES During construction, the contractor shall keep the site well drained at all times. Any waste material accumulated during construction, which will not be reused in later construction, shall be removed from the site and disposed of in a responsible and legal manner. All unstabilized soil stockpiled temporarily shall be covered with a tarp or other suitable stabilization (seeded) in order to prevent washoff when precipitation is imminent. Temporary seeding shall consist of a modified Formula E - Lolium Multiflorum 100% pure live seed (pls), or equivalent, and shall be placed at the rate of 28 pounds per acre. Temporary seeding shall be applied to those areas that are a potential erosion problem during construction. Disturbed areas that are to be stabilized immediately. If conditions do not permit temporary seeding, mulching shall be employed. Additionally, commercial fertilizer ( ) at pounds per acre, agricultural lime at 1.94 tons per acre, and straw mulch at 2.9 tons per acre. 5

8 Silt barrier fence shall be placed at critical erosion areas, as shown on the Plan, in order to prevent sediment from entering onto public roadways, adjacent properties and waterways. Stabilized construction entrances shall be placed at the point of construction ingress and egress. This structure will prevent tracking and flowing of sediment onto the public roadway. The entrance shall remain functional for the duration of the project. Where dust or wind erosion is a problem, the unstable surface(s) shall be sprinkled with water or other suitable dust suppressor. Any water pumped from sanitary, storm, or utility trenches, for any reason, shall be directed through a sediment filter bag (dirt bag) conforming to Pennsylvania Department of Transportation Specifications. The contractor shall employ measures during construction to prevent spills of fuels or lubricants. If a spill occurs, it shall be controlled immediately to prevent its entry into nearby waterways. All earthmoving activities shall be carried out in such a manner as to minimize the amount of disturbed area. Responsibility for implementing erosion and sedimentation control shall be designated to a minimum of one individual who will be present at the project site daily. When the Engineer, Municipal Official, or County Representative determines that erosion control measures are necessary, that were not foreseen in the design stage, said official shall estimate the erosion potential and select measures on the basis of both cost effectiveness and the consequences of the erosion. Any temporary erosion control measure applied to exposed soil surfaces shall remain functional until vegetation cover is sufficiently established. All temporary erosion and sedimentation control measures shall be subject to applicable regulations of the Department of Transportation Form 408 Specifications, most recent edition. PERMANENT CONTROL MEASURES 1. Permanent soil protection will be completed as early as practical. 2. Permanent seeding and mulching will be incorporated into the construction phase during the approved planting season. 6

9 1. All areas disturbed by construction, other than those receiving rip-rap, landscaping or paving (including gravel) shall be stabilized by applying a seed mixture to establish an erosion resistant stand of vegetation. The following is recommended for lawn type applications: a. Seeding [Formula D] (1) Festuca arundinacea - 70% total lbs/acre (2) Festuca rubra - 30% total lbs/acre b.

All erosion and sedimentation controls shall be implemented in accordance with the Erosion and Sedimentation Control Handbook and the Chester County Conservation District, where applicable. RECOMMENDED STAGING OF CONSTRUCTION ACTIVITIES All earth disturbance activities shall proceed in accordance with the following sequence. Each stage shall be completed in compliance with Chapter 102 regulations before any following stage is initiated. At least 7 days before starting any earth disturbance activities, the operator shall invite all contractors involved in those activities, the landowner, all appropriate municipal officials, the erosion and sedimentation control plan preparer, and a representative of the Chester County Conservation District to schedule an on-site pre-construction meeting. Also, at least 3 days before starting any earth disturbance activities, all contractors involved in those activities shall notify the Pennsylvania One Call System Inc. at for buried utilities location. Before implementing any revisions to the approved erosion and sediment control plan or revisions to other plans which may affect the effectiveness of the approved E&S control plan, the operator must receive approval of the revisions from the Chester County Conservation District. The operator shall remove from the site, recycle or dispose of all building materials and waste in accordance with the Department s Solid Waste Management Regulations at 25 PA Code e. seq. and et seq. 8

11 Before disposing of spoil or receiving borrow for the site, the operator must assure that each spoil or borrow area has an erosion and sediment control plan approved by the Chester County Conservation District, and which is being implemented and maintained according to Chapter 102 regulations. Stabilization uniform erosion resistant perennial vegetation is established to the point where the surface soil is capable of resisting erosion during runoff events. The standard for this vegetative cover will be a uniform coverage density of 70% across the disturbed area. Upon completion of an earth disturbance activity, the operator shall stabilize immediately the disturbed areas to protect from accelerated erosion. During nongerminating periods, mulch must be applied at the specified rates. Disturbed areas which are not at finished grade and which will be redisturbed within 1 year may be stabilized in accordance with temporary seeding specifications. Disturbed areas, which are either at finished grade or will not be redisturbed within 1 year, must be stabilized in accordance with permanent seeding specifications. Until the site has achieved final stabilization, the owner and /or contractor shall properly implement, operate and maintain all the best management practices. Maintenance shall include inspections of all erosion and sedimentation control after each runoff event and on a weekly basis. All preventative and remedial maintenance work, including clean out, repair, replacement, regrading, reseeding, remulching, and renetting, must be performed immediately. CONSTRUCTION SEQUENCE The Clover Mill Road Bridge and roadway will be under construction for approximately 140 working days. The area under construction will be closed to through traffic and a detour will be in place to direct traffic. Stage 1 - Start to Day 140 Place 18-inch and 30-inch silt fence in the areas shown on the Erosion and Sedimentation Control Plans, Sheet 3 before any construction may proceed (Day 1). The silt fence shall be constructed as per the DEP Erosion and Sedimentation Pollution Control Program Manual, March 2000, Worksheet #2 (Appendix B) or Pennsylvania Department of Transportation, Publication 72, RC-70M, Sheet 2 of 5 (detailed on plan sheet 2 of 3). The flow in the stream will be maintained as shown in the DEP Erosion and Sedimentation Pollution Control Program Manual, March 2000, Figure 35a: In-Stream Cofferdam Diversion (Appendix B). The sandbag cofferdams shall be constructed as shown on the Erosion and Sedimentation Control Plans, Sheets 3 of 3. Upon completion of the erosion and sedimentation control device installation, remove the existing structure and install the bridge. Upon the completion of the new structure and the roadway improvements, seed and mulch the entire disturbed area including wetland disturbance in 9

12 accordance with Pennsylvania Department of Transportation, Publication 408, Section 804 and Section 805 of DEP Erosion and Sedimentation Control Plan, August 1994, Worksheet #8. After the roadway embankments slopes are seeded erosion control blankets should be placed in order to stabilize the slopes. Upon completion of the construction, the flow in the stream shall be returned to its pre-construction condition and the rest of the erosion and sedimentation control devices shall be removed. MAINTENANCE OF CONTROL STRUCTURES The erosion and sedimentation control for the subject property requires no detailed maintenance. However, certain periodic duties shall be performed by the contractor in order to assure proper control. Any debris accumulated at silt barriers will be removed and properly disposed of in a responsible manner. Barriers shall be checked and realigned or reset as required. Any debris or solid waste material accumulated from construction activities shall be removed from the site and disposed of in an approved landfill. Construction waste shall not be buried on the subject site. Vegetative stabilization will be periodically inspected for proper growth. Any areas not responding will be promptly reseeded. Areas, which show signs of erosion prior to stabilization shall be graded, reseeded, and remulched immediately. The stabilized construction entrance shall be cleaned and redressed when voids become choked with mud and sediment. Miscellaneous adjustments and corrections shall be made to any erosion control structure as deemed necessary by the Engineer, Municipal Official, or County Representative in order to correct unforeseen problems caused by a storm prior to stabilization. GENERAL NOTES 1. Only limited disturbance will be permitted to provide access to sediment control facilities for grading and acquiring borrow to construct those controls. 2. Erosion and sedimentation controls must be constructed, stabilized, and functional before site disturbance within the tributary areas of those controls. 3. After final site stabilization has been achieved, temporary erosion and sedimentation controls must be removed. Areas disturbed during removal of the controls must be stabilized immediately. 4. Vehicles may neither enter directly to nor exit directly from project site onto SR At the end of each working day, any sediment tracked or conveyed onto a public roadway will be removed and redeposited onto the construction site. Removal can be completed through use of mechanical or hand tools, but must never be washed off the road by use of water. 10

13 6. Sediment removed from E&SPC controls and facilities shall be disposed of in landscaped areas outside of steep slopes, wetlands, floodplains or drainage swales and immediately stabilized, or placed in topsoil stockpiles. 7. All pumping of sediment laden water shall be through a dirt bag filtration device, or equivalent sediment removal facility, over non-disturbed vegetated areas. Discharge points should be established to provide for maximum distance to active waterways. 8. Should unforeseen erosive conditions develop during construction, the contractor shall take action to remedy such conditions and prevent damage to adjacent properties as a result of increased runoff and/or sediment displacement. Stockpiles of wood chips, hay bales, crushed stone and other mulches shall be held in readiness to deal immediately with emergency problems of erosion. 9. The contractor is advised to become thoroughly familiar with the provisions of the Appendix 64, Erosion Control Rules and Regulations, Title 25, Part1, Department of Environmental Protection, Subpart C, Protection of Natural Resources, Article III, Water Resources, Chapter 102, Erosion Control. 10. A copy of this erosion and sedimentation control report and plans must be posted at the construction site. 11. Stockpile heights must not exceed 35. Stockpile slopes must be 2:1 or flatter. 12. Mulch with mulch control netting or erosion control blankets must be installed on all slopes greater than 3:1. 11
