1.3 Nature and Sequence of Construction Activity

Describe the general scope of the work for the project, major phases of construction, etc:

The purpose of this project is to rehabilitate Newfound Gap Road from TN milepost 0.0 to TN milepost 6.3 in the great Smoky Mountains National Park. The rehabilitation includes removal of the deteriorated pavement surface from the existing two-lane roadway; placement of a new asphalt overlay, including reconstruction of structurally deficient pavement sections; paving pullouts. The road surface and pullouts will be replaced with a new asphalt surface. Work within the culverts will be limited to the repair or replacement of the existing structure. Various existing gravel pullouts will be stabilized and paved which will require minor grading. A portion of the roadway near the Carlos Campbell Overlook has subsided over the years. Two permanent ground anchor walls (PGA Walls) will be constructed at the toe of the slope to stop further subsidence.

The purpose of this project is to rehabilitate schedule C of the project (renumbered as NP- GRSM 1A29) Newfound Gap Road from TN milepost 0.0 to TN milepost 1.8 in the Great Smoky Mountains National Park. Work between TN milepost 1.8 and TN milepost 6.3 has been completed. The rehabilitation includes full depth pavement reconstruction, final asphalt course, box culvert repair, repointing/repair of existing stone masonry, resetting stone curb, repair of drainage structures, pullout construction, shoulder stabilization, pavement markings, signing, installation of steel backed timber guardrail and traffic control.

Instructions:

― Briefly describe the nature of the construction activity and approximate time frames (one or more paragraphs, depending on the nature and complexity of the project).

― For more information, see SWPPP Guide, Chapter 3.A.

An Environmental Assessment for this project was completed in March of 2010 and a Finding of No Significant Impact was signed on June 22, 2010. Potential impacts endangered or threatened species within the project corridor were found to be negligible to minor. A full list of endangered or threatened species can be found in the environmental assessment.

What is the function of the construction activity?

Residential Commercial Industrial Road Construction Linear Utility Other (please specify): See above

Estimated Project Duration: 24 months

1.4 Soils, Slopes, Vegetation, and Current Drainage Patterns

Soil type(s):

A USDA soil survey for the project corridor is included in Appendix A.

Slopes (describe current slopes and note any changes due to grading or fill activities):

The project traverses steeply sloping terrain over the entire length. The natural slope inclinations along the right-of-way vary from 2 horizontal to 1 vertcal (2H:1V) to 1H:1V. The proposed grading will generally follow the slopes of the existing roadway shoulders.

Drainage Patterns (describe current drainage patterns and note any changes dues to grading or fill activities):

The existing drainage patterns generally sheet flow off of the pavement, across the shoulder, down the fill slope or roadside ditch and to the receiving waterways. The drainage patterns will not be significantly altered due to the proposed grading. Channelized flow from curb and gutter sections will be directed through paved water ways to rip rap pads to dissipate the concentrated flow.

Instructions:

― Describe the existing soil conditions at the construction site including soil types, slopes and slope lengths, drainage patterns, and other topographic features that might affect erosion and sediment control.

― Also, note any historic site contamination evident from existing site features and known past usage of the site.

― This information should also be included on your site maps (See SWPPP Guide, Chapter 3.C.).

Vegetation:

The project corridor is a maintained roadway. The existing vegetation along the roadway shoulders is grasses and low shrubbery. Dense forests exist outside of the roadway prism. It is anticipated that the proposed grading and land disturbance will be within the existing maintained roadway prism.

1.5 Construction Site Estimates

The following are estimates of the construction site.

Total project area: 29.2* acres Construction site area to be disturbed : 2.1 acres Percentage impervious area before construction: % Runoff coefficient before construction:

Percentage impervious area after construction: % Runoff coefficient after construction

*Total project area consists of the existing roadway prism, pavement and maintained shoulders for the entire GRSM 1A28 project.

The increase in impervious area is negligible. The proposed paved pullouts will fall within the same general footprint as an existing compacted gravel pullout.

― Estimate the area to be disturbed by excavation, grading, or other construction activities, including dedicated off-site borrow and fill areas.

― Calculate the percentage of impervious surface area before and after construction ― Calculate the runoff coefficients before and after construction.

― For more information, see SWPPP Guide, Chapter 3.A and Appendix C.

1.6 Receiving Waters

Description of receiving waters:

The receiving waters of this project are named and un-named tributaries to West Prong Little Pigeon River to the Pigeon River to French Broad River, a tributary to the Tennessee River.

Description of storm sewer systems:

The existing storm system consists of cross pipes/culverts and very few catch basins with a single pipe system. A majority of the storm system is conveyed with roadside ditches and waterways.

Description of impaired waters or waters subject to TMDLs:

Other:

1.7 Site Features and Sensitive Areas to be Protected

― Describe unique site features including streams, stream buffers, wetlands, specimen trees, natural vegetation, steep slopes, or highly erodible soils that are to be preserved.

― Describe measures to protect these features.

― Include these features and areas on your site maps.

― For more information, see SWPPP Guide, Chapter 3.A and 3.B.

― List the waterbody(s) that would receive stormwater from your site, including streams, rivers, lakes, coastal waters, and wetlands. Describe each as clearly as possible, such as Mill Creek, a tributary to the Potomac River, and so on.

― Indicate the location of all waters, including wetlands, on the site map.

― Note any stream crossings, if applicable.

― List the storm sewer system or drainage system that stormwater from your site could discharge to and the waterbody(s) that it ultimately discharges to.

― If any of the waterbodies above are impaired and/or subject to Total Maximum Daily Loads (TMDLs), please list the pollutants causing the impairment and any specific requirements in the TMDL(s) that are applicable to construction sites. Your SWPPP should specifically include measures to prevent the discharge of these pollutants.

― For more information, see SWPPP Guide, Chapter 3.A and 3.B.

― Also, for more information and a list of TMDL contacts and links by state, visit www.epa.gov/npdes/stormwater/tmdl.

1.8 Potential Sources of Pollution

Potential sources of sediment to stormwater runoff:

Land grading operations.

Potential pollutants and sources, other than sediment, to stormwater runoff:

Normal pollutants contained within a typical construction site. It will be the responsibility of the contractor to contain any pollutants.

Trade Name Material Stormwater Pollutants Location

Description of unique features that are to be preserved:

Steep Slopes outside of roadway prism, blue line streams.

Describe measures to protect these features:

The contractor will be required to install and maintain the appropriate erosion control measures throughout all phases of the project to minimize the risk of sediment leaving the construction area. Furthermore, the work around the blue line streams will be limited to the maintenance activities for the existing culvert crossings.

― Identify and list all potential sources of sediment, which may reasonably be expected to affect the quality of stormwater discharges from the construction site.

― Identify and list all potential sources of pollution, other than sediment, which may reasonably be expected to affect the quality of stormwater discharges from the construction site.

Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment.

Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases.

Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app?

agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/ state_offices/).

Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations.

The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey.

Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

How Soil Surveys Are Made Soil surveys are made to provide information about the soils and miscellaneous areas in a specific area. They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles.
