HomeMy WebLinkAboutWPO201600036 Plan - E&S WPO VSMP 2016-06-10Erosion and Sediment Control Narrative For: Carver Bridge Parcel: 05900-00-00-037C6 Pallas Hill Lane (no assigned address) Charlottesville, Virginia Project Description: The proposed work includes the construction of a new bridge for access to Brook Rd. The total area of the parcel is 4.62 acres, of which 0.27 acres will be impervious surface. The total on-site disturbed area is approximately 0.38 acres, most of which will be created by providing an access road to the bridge site. The Work is anticipated to begin upon approval of the erosion and sediment control plan. Work will include clearing, grubbing and grading, as shown on the plans. Erosion control measures shown will protect the stream below from receiving silt -laden runoff. Existing Site Conditions: The site is currently undeveloped with the exception of an existing driveway. The site generally slopes from northwest to southeast at varying slopes. No critical slopes will be disturbed. The pre and post drainage patterns will be the same. There are no existing drainage or erosion problems directly associated with this site. Runoff from the site discharges into Ivy Creek, which borders the property to the southeast. The proposed erosion and sediment control measures will eliminate potential for erosive damage to private properties. Since the site is not openly exposed to winds, and the limited amount of site work, dust control should not be an issue. Adjacent Property: The property is bounded on all sides by large, single-family properties with open and wooded terrain. Off-site Areas: No off-site areas will be disturbed. Soils: 4D - Ashe loam 4E - Ashe loam 19B - Cullen loam 36C - Hayesville loam Critical Erosion Areas: There are no critical erosion areas associated with this project. Erosion and Sediment Control Measures: Unless otherwise indicated, all vegetative and structural erosion and sediment control practices will be constructed and maintained according to minimum standards and specifications of the Virginia Erosion and Sediment Control Handbook. Additional measures may be required during construction by the County Erosion Control Official, as needed. Structural Practices: Safety Fence: (SAF) 3.01 A protective barrier installed to prevent access to an erosion control measure. (To be installed along limits of disturbance within the stre(atrt buffer) Construction Entrance: (CE) 3.02 A stabilized stone pad with a filter fabric underliner located at points of vehicular ingress and egress on a construction site. (To be installed at entrance to remove soil.front tit -es prior to travel on public roads) Silt Fence: (SF) 3.05 Silt fence (wire -supported) shall be constructed along the lower limit of graded areas. (To be installed as shown on the plan at the base of the slopes created by the proposed excavation. ) Permanent Seeding (PS) 3.32 Establishment of perennial vegetative cover by planting seed where permanent, long-lived vegetative cover is needed on fine -graded areas. (Permanent seeding will be provided on all disturbed areas. Given the limited scope of work and schedule, no temporary seeding is necessary.) Mulching (MU) 3.35 Application of plant residues to disturbed surfaces to prevent erosion and reduce overland flow. Apply to all seeded areas. (Tobe installed with Permanent Seeding) Vegetative Practices: Temporary Seeding 3.31: All areas disturbed by construction that will not be brought to final grade for a period of more than 30 days, will be stabilized by establishing a good stand of grass. Lime 3.31: Unless it is known that the site will remain undisturbed for many months, lime is not necessary. If necessary, the amount will be determined by Soil Test, or 3 tons per acre of pulverized agricultural limestone, uniformly applied to surface to be seeded during seedbed preparation and incorporated into the top 2-4 inches of soil. Fertilizer 3.31: 600 pounds per acre of 10-20-10 or equivalent, uniformly applied to the surface to be seeded during seedbed preparation and incorporated into the top 2-4 inches of soil. Surface roughening 3.31: Where disturbed soils have been compacted, loosen soils by discing, raking, or whatever acceptable means available to receive seed. Seed 3.31: Seed shall be broadcast evenly and planted from % to i inch deep. Seasonal seed selection shall be as follows: • Sept. 1 - Feb. 15: 50/50 Mix of Annual Rye and Winter Rye, 50-100 Ib/ac. • Feb. 16 - April 30: use Annual Rye, 60-100 Ib/ac. • May 1 - Aug. 31: use German Millet, 50 Ib/ac. Areas which fail to establish vegetative cover adequate to prevent rill erosion will be reseeded as soon as such areas are identified. Management Strategies: Construction should be sequenced so that grading operations can begin and end as quickly as possible. Areas that are not to be disturbed shall be clearly marked by the placement of the erosion control measures prior to construction. The job superintendent shall be responsible for the installation and maintenance of all erosion and sediment measures. Where construction vehicle access routes intersect paved public roads, provisions shall be made to minimize the transport of sediment by vehicular tracking onto the paved surface. Where sediment is transported onto a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. Stabilization of Denuded Areas and Soil Stockpiles: Permanent or temporary soil stabilization must be applied to denuded areas within 7 days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within 7 days to denuded areas which may not be at final grade but will remain dormant (undisturbed) for longer than 14 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 water. Applicable practices include vegetative establishment, mulching and the early application of gravel base on areas to be paved. Soil stabilization measures should be selected to be appropriate for the time of year, site conditions and estimated duration of use. Timing and Stabilization of Sediment Trapping Measures: Sediment barriers and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a first step in any land disturbing activity and shall be made functional before upslope land disturbance takes place. Stabilization measures shall be applied to earthen structures such as dams, dikes, and diversions immediately after installation. Disposal of Temporary Measures: All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the local program administrator. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be removed and replaced with suitably compacted soils, or, where applicable, permanently stabilized to prevent further erosion and sedimentation. Maintenance: All erosion and sediment control structures and systems shall be maintained, inspected, and repaired weekly and after each significant rainfall or as needed to insure continued performance of their intended function. Any damage to structural measures shall be repaired immediately. Silt traps are to be cleared at 50% storage capacity level. All seeded areas are to be checked to insure a good stand is maintained.

Temporary soil stabilization shall be applied within seven 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 which protect soil from the erosive forces of raindrop imipact and flowing water.
