IMPACT ANALYSIS OF THE ALTERNATIVES Task Human Environment The consultant will examine and analyze the human (social and economic) environment in the vicinity of the project area, and the possible impacts to it resulting from the project. The Stage 0 Feasibility Study provides generalized land use and demographic data based on the 2000 Census. The consultant will update this information to facilitate the development and evaluation of build alternatives. Socio-Economic Data and Impacts Data from the 2010 Census will be used to update population and socio-economic characteristics within the project study area, including neighborhoods which may be adversely affected by the proposed action. Community Services and Facilities Impacts to community services and facilities for each alternative shall be addressed in the EA along with the social and economic impacts of the proposed action on the community. This analysis shall also include anticipated impacts to community services and facilities during construction. The consultant will evaluate possible mitigation or enhancement measures to reduce or lessen adverse impacts, if any, on the community. To assist in this analysis, the consultant will contact and coordinate with local officials and community leaders. 5

6 Land Use and Zoning Land use information will be obtained from recent RPC and Parish master planning efforts, discussions with local officials, and the site investigation. Impacts on current development trends and state or local government plans and policies within the project study area will be discussed. Development trends will include land use, transportation, public facilities, housing, community services, and other scheduled or planned facilities. Environmental Justice The consultant will evaluate whether the project has a disproportionate adverse impact on minority or low-income groups. If the proposed project impacts low income and/or minority populations, a thorough research/analysis along with mitigation actions/plans shall be discussed in the EA in accordance with all applicable state/federal laws. Land Use, Socio-Economic and Community Facilities Information In GIS Map Format and Associated Data Tables Task Environmental Site Assessment A Phase 1 Environmental Site Assessment will be performed for the study area in accordance with the latest version of ASTM Standard (E ). The Phase 1 Site Assessment has four components: Record Review, Site Reconnaissance, Interviews and Report. Three (3) copies of the draft report will be submitted to DOTD s Environmental Section for review. Once the report is approved, ten (10) copies of the final report will be submitted. If recognized environmental conditions are found, the consultant will meet with the TAC to discuss appropriate actions. Environmental Site Assessment Process: Record Review, Site Reconnaissance, Interviews, and Draft and Final Report Task Recreational Resources 4(f) and 6(f) All public recreational and public park land will be identified and delineated within the logical termini. Research, analysis, and documentation of compliance with Section 4(f) of the DOT Act will be conducted by the consultant for any Section 4(f) property affected by the proposed action. Use of Land and Water Conservation Funds within the project study area will be identified by the consultant. If such funds are present, the consultant will prepare all documentation for coordination with the appropriate agencies. Research and Documentation of Section 4(f) and 6(f) Compliance, as Required Task Historic/Cultural Resources After initial coordination with the State Historic Preservation Officer (SHPO) and DOTD s Environmental Section, the determined Area of Potential Affect (APE) will be surveyed to 6

7 determine the presence of National Register of Historic Places eligible archaeological sites, both historic and prehistoric, as well as any standing structures or other places or objects, including bridges, eligible for listing on the National Register of Historic Places. The survey and report will meet the current standards of the Louisiana Standard of Archaeology for Phase I and Phase II Surveys. Personnel will meet the Secretary of the Interiors Standards for Historic Preservation and Archaeology. All research and documentation necessary to comply with Section 106 of the National Historic Preservation Act and Section 4(f) Department of Transportation Act will be prepared by the consultant (i.e., Preliminary Case Reports, Documentation with a Determination of Effect). All coordination with the SHPO s office will be through DOTD s Environmental Section or with the express approval of the Environmental Section. Two unbound copies of the survey forms for each standing structure and archaeological site will be submitted to the Environmental Section. Five (5) copies of the draft Cultural Resources Survey will be submitted to DOTD s Environmental Section for review, and following DOTD approval, five (5) copies of the final Cultural Resources Survey and PDF on Disc. Draft and Final Report on Historic and Cultural Resources Task Traffic Study An initial traffic analysis was conducted in the Stage 0 Feasibility Study based on spot data collected at various intersection locations over the period Future year traffic was estimated from RPC s Regional Transportation Model and limited project data collection efforts. An updated traffic study is necessary due to continued residential and commercial development in upper Plaquemines Parish, and new expansion plans announced for the Naval Air Station/Joint Reserve Base (NAS/JRB). The study will be used to more accurately identify current traffic conditions and traffic impacts associated with the build alternatives and to inform the public about traffic impacts on local streets and intersections within the project area for the opening year and design year of the project. The consultant will review the Stage 0 traffic volume data ( ) and traffic signal data at signalized intersection locations. New traffic counts, turning movement counts, and intersection capacity analysis will be required at the following major intersection locations: LA Hwy. 23 at Lapalco/Behrman, Engineers Road, Barriere Road, and Woodland/LA Hwy Count data will also be needed for various local streets (estimated six count locations) where traffic re-routing may be required due to the build alternative(s). The consultant will discuss the requirements of the Traffic Study with RPC/DOTD prior to initiating data collection activities. RPC s recently updated Transportation Model will be used to assist in establishing horizon year traffic forecasts using the latest LADOTD Traffic Noise Policy, the consultant will prepare a draft Traffic Analysis Report for submission to RPC/DOTD for review and comment prior to finalization. Upon approval, the consultant will prepare the final Traffic Analysis Report and provide five (5) copies along with an electronic version in.pdf format to RPC and DOTD, respectively. Tasks Deliverables: Traffic Data and Analysis Report 7

8 Task Traffic Noise Analysis A noise study is required for alternatives where the horizontal or vertical alignment of the roadway is substantially changed or where capacity is added. Noise samples will be measured and the current FHWA approved noise model (TNM 2.5) using the latest LADOTD Traffic Noise Policy. The consultant will submit a noise protocol for approval prior to initiating field measurements and modeling. The consultant will conduct a reconnaissance of the project area to confirm location of potential impacted residents, businesses, and other receptors; perform a document search to ascertain the existence of planned, designed and programmed activities; acquire field measurements of noise level; model the noise for each alternative for existing, build and design years; determine highway traffic noise levels for each alternative for the peak-hour; determine noise impacts at sensitive receptors; including a comparison of impacts for the existing condition with the build year and design year; and determine the reasonableness and feasibility of all noise abatement measures in accordance with DOTD policy. A separate Traffic Noise Report is required. The report shall outline the methodology used and include a description of the model used. The analysis will include documentation of the input data assumptions; identification of other noise sources in the corridor; discussion of model noise levels for each alternative, including exhibits showing receptor sites and noise contours; discussion (with table) of traffic noise impacts resulting from existing condition, build year and design year; abatement measures considered and whether they are reasonable and feasible. The report should contain a completed copy of the Department s worksheet as well as an Appendix with hardcopy printout of model input and outputs for each run as well as digital files on a CD. For review purposes, five (5) reports will be submitted and, for each revision, five (5) revised copies will be required. Once the report is approved, five (5) copies of the final will be required, including one CD containing input/output files. The text part of the final Noise Report will be included in the Appendix of the EA. Traffic Noise Study and Report Task Air Quality The impact on regional air quality will be discussed. Information on the existing air quality for the region can be obtained from Louisiana Department of Environmental Quality (DEQ). Discussions concerning conformity (transportation and general) will be included in the air analysis. Project level modeling for CO is not required but a comparative analysis with a recent nearby project will be needed to assess any impact on air quality from the proposed project. DOTD will provide air quality analyses from a similar location for comparison to the proposed build alternatives. Air Quality Analysis of Build Alternatives 8

9 Natural Environment Task Data Collection and Research The consultant will conduct internet and literature searches, letter correspondence, and telephone contacts with local, regional and state agencies to obtain existing digital and printed information about the project area. Contacts with agencies will be discussed in advance with RPC/DOTD and all correspondence and coordination will be documented. The consultant will assemble available data and will conduct a reasonableness check of the data prior to use. Field reviews will be conducted to help verify existing conditions and collected environmental information. Existing Natural Environmental Characteristics and Conditions In GIS Map Format and Associated Data Tables Task Wetlands Wetlands in the project area will be identified and delineated utilizing the latest appropriate Corps of Engineers guidelines. A Wetlands Finding, using latest FHWA criteria will be written. Information referenced may include infrared photography, National Wetlands Inventory (NWI) maps, quadrangle maps, soil maps, etc. Referenced information will not substitute for an on-site field determination which will be made. Acreage of wetlands impacted and their value will be calculated and exhibits suitable for reproduction indicating the limits of wetlands in the area affected by the project and the areas to be impacted will be made. All paperwork necessary for the permit application will be prepared by the consultant for the LADOTD s use in obtaining the necessary permits. Photographs of each soil sample with the appropriate Munsell soil chart in the same photograph will be included in the report. Each wetland area will be located on a quadrangle sheet as well as a layout map with the station numbers noted. The consultant will identify and discuss appropriate mitigation measures. Two (2) copies of the draft and two (2) copies for each revision are required. Once approved, five copies of the final report will be required. A color digital copy of the final Wetland Finding in pdf format will also be required. Draft and Final Wetlands Delineation Report Task Wildlife Impacts and Threatened/Endangered Species For each alternative alignment, water body modifications and impacts to fish and wildlife resulting from the loss, degradation, or modification of aquatic or terrestrial habitat will be discussed and identified on project maps. Information from the U.S. Fish and Wildlife Service, the National Marine Fisheries Services, and the State Department of Wildlife and Fisheries will be collected to determine the presence of listed and proposed threatened or endangered species and designated and proposed critical habitat in the project area. Biological assessments will be performed if needed. A summary of the results of meetings and consultation and identification of mitigation measures to avoid impacts will be provided. 9

10 The dominant vegetation cover for the alternative alignment areas will be identified through a literature review and from the findings of the wetland delineation. Research and field methods will also concentrate on identification of known threatened/endangered species of vegetation. Wildlife and waterfowl refuges will be avoided, but if they cannot be avoided, the consultant will perform all work necessary to complete the Section 4(f) evaluation. Summary Biological/Ecological Assessment Task Other Other items that will be evaluated and coordinated with the appropriate agencies include but are not limited to coastal zone, 100-year floodplain, and water wells. Some of these items utilize standard forms; other coordination is by letter or permit application. Items of special or local interest should also be noted and evaluated within the context of the project. Agency Coordination and Support Materials (meetings, , forms, letters) Task Secondary and Cumulative Impacts A discussion of secondary and cumulative impacts of the proposed action (including its benefits) on the human, physical, and natural environment is required and will be included in the EA. Summary Analysis of Secondary and Cumulative Impacts for Each Alternative Task Summary of Mitigation and Permits A summary of mitigation and permits shall be prepared by the consultant and placed at the beginning of the EA. All potential permits and their requirements to implement the project will be identified. Any mitigation measure or enhancement committed to by Plaquemines Parish or DOTD will be listed in this summary. Summary of Mitigation Measures and Required Permits Task 4.7 GIS/Project Mapping The consultant will develop a geographical information system (GIS) in ArcInfo format for the documentation and mapping of environmental and socio-economic data (Tasks 3.2, 3.3 and 4.1). RPC will provide recent aerial photography for use on the project. Project mapping will incorporate the Stage 0 build alternatives and estimated right-of-way with the GIS database and environmental constraints.

Large format presentation exhibits will be prepared for public meetings and line and grade exhibits (plan/profile sheets) will be developed for the Environmental Analysis. LIDAR data will be 10

11 obtained by the consultant for use in developing vertical geometry for the build alternatives and for use in the traffic noise analysis. Project Mapping of Conceptual Build Alternatives with Existing Socio-Economic Conditions, and Environmental Features and Constraints V. ALTERNATIVES ANALYSIS Task The Build Alternatives All alternatives examined in the Stage 0 Feasibility Study will be summarized in the environmental document. The alternatives eliminated from further study will be identified and reasons for their elimination, as presented in the Feasibility Study, will be presented at the initial public meeting and restated in the EA. Other reasonable alternatives, as introduced through the public process (Task 2.4) and consistent with the purpose and need of the project, shall be discussed in the environmental document. The three build alternatives that were identified in the Stage 0 Feasibility Study (July 2009) will be refined and undergo further analysis as part of the Environmental Assessment process. One fixed high-level bridge and two movable bridges, each with a different clearance from the bottom of the bridge to the mean high tide level in the Gulf Intracoastal Waterway (GIWW), comprise these alternatives: - Alternative 1B: 100 ft. clearance fixed bridge, including the Warren St. extension - Alternative 2A: 70 ft. clearance movable bridge - Alternative 3B: 60 ft. clearance movable bridge A review will be performed of the horizontal and vertical layout of the build alternatives that were developed as part of the Stage 0 Feasibility Study. In developing conceptual plans for the build alternatives, including those introduced through the public process, the consultant will adhere to the design criteria contained in DOTD s Roadway Design Procedure and Details Manual. Large-format, presentation exhibits will also be prepared for public meetings (Tasks 1.6 and 2.4), while line and grade (plan/profile sheets) will be developed for the EA document. LIDAR data will be obtained by the consultant for use in developing vertical geometry for the build alternatives and for use in the traffic noise analysis. Development of Conceptual Plans of the Three Build Alternatives Task The No Build Alternative The EA will necessarily consider the consequences associated with a No Build Alternative. The consultant will work with the RPC, Plaquemines Parish, and DOTD to identify land use changes and committed transportation improvement projects which relate to the Belle Chasse/LA Hwy. 23 corridor, particularly within the project area. Consideration will necessarily be given to the condition and maintenance costs of the existing tunnel and bridge system as well as the cost to commuters from bridge openings and travel delays. These factors and projected traffic volumes for 11

12 the horizon year will be used to define the impacts (positive and negative) associated with a No Build condition. Summary Report on Impacts Associated with No Build Alternative for EA Inclusion Task Impact Evaluation of Alternatives Analysis of each alternative, including the no-build, will be made. Items to be considered include, but are not limited to, traffic patterns, permits, land use, community/social, economic, historic, cultural, recreational, archaeological, noise, air, wetland, floodplains, endangered or threatened species and/or their habitat. Information will be based on previous and on-going studies and through secondary sources, field review, or through meetings and discussions with the public, public agencies, organizations, individuals and elected officials. Some of these items may require the production of a separate document in addition to the analysis in the Environmental Assessment. Potential mitigation measures designed to reduce or alleviate impacts will be discussed in the document. The evaluation of impacts will be thorough and complete as they relate to the human environment, physical environment and natural environment, respectively. Summary Report in Text and Graphics Format for Comparing Impacts Associated with each Alternative VI. LINE AND GRADE STUDY Task Design Criteria The consultant will identify design criteria for use on the project based on the information contained within the Stage 0 Feasibility Study and as updated as part of this task. The geometry for the build alternatives shall meet DOTD s Roadway Design Procedure and Details Manual. The design criteria will address proposed roadway and bridge facilities, including functional classification, design speed, lane widths, horizontal and vertical clearances, and grade requirements, among other factors. The consultant shall prepare a table of design criteria to be included in the report documenting the design criteria that will be used in developing all geometrics. The design criteria will be based on DOTD design standards supplemented with the American Association of State Highway and Transportation Officials (AASHTO) guidelines for roads and bridge structures. The consultant shall submit the design criteria for DOTD review and approval prior to advancing with production of conceptual typical sections and project concepts. Context sensitive solution principles shall be utilized in determining recommended project features. Draft and Final Versions of Project Design Criteria 12

13 Task Plan and Profile Conceptual line and grade (plan/profile) drawings will be developed for each build alternative to determine right-of-way needs. Upon approval of the layouts by RPC and DOTD, the drawing files (geometry and ROW) will be converted to shape files for use in project GIS mapping and converted to dxf format for use in public meetings and for conduct of the traffic noise analysis. Each alternative will be described in text and graphic form to clearly describe for the public the impacts (positive and negative) associated with each alternative. Conceptual drawings showing modifications to intersections or local streets impacted by the build alternatives will also be prepared in a format suitable for public review and comment. Conceptual Layouts of Build Alternatives Task Typical Sections The consultant will prepare roadway and bridge typical sections for the build alternatives. These typical sections will be developed for use in public meetings in a graphical format that is easily understood by the general public. The typical sections may vary by location along the proposed route due to traffic volumes, level of service, design criteria, access control, median and shoulder treatments, and intersection treatments. The consultant shall submit the typical sections to DOTD for review. The proposed typical sections shall meet current design criteria as required by DOTD. The consultant will prepare electronic files for the proposed geometry and existing and anticipated right-of-way for each build alternative. The information will be displayed on the project area base map or other aerial photography to enhance public understanding of impacts associated with each alternative. Alternatives will be developed at a scale of 1 = 100. Draft and Final Versions of Bridge and Roadway Typical Sections;Conceptual Layouts of Each Alternative Task Right-of-Way and Utilities Based on the Line and Grade analysis, the consultant will refine the Right-of-Way requirements for each build alternative. This estimate will include land cost, number and type of structures to be acquired and their cost, and residential and/or business relocation cost. The consultant shall estimate anticipated right-of-way land acquisition costs by obtaining current real estate prices per acre for each type of property (i.e. commercial, residential, etc.) or cost data on comparable real estate transactions in the project area. For commercial and residential real estate, the relocation costs of businesses or homes shall also be estimated as required. The consultant will identify all public and private sector utilities located within the study area from various sources including DOTD, Plaquemines and Jefferson Parishes, and utility companies. Utilities include, but are not limited to, the following: power, telephone, communication cable, drainage, sewer, water, and traffic signal system infrastructure. Data coverage will extend beyond the limits of the proposed build alternatives to ensure that relocation limits are adequately addressed. All utility relocation research shall include contacting both the local DOTD district and headquarters utility relocation sections for these potential costs. 13

14 The geometric layout and required ROW will be shown with the utility layer, depicting types of utilities and estimated length of relocation. Meetings or telephone contact with utility owners will be necessary to confirm existing status or future upgrades to utility infrastructure. Utility relocation costs will be developed for each build alternative based on the unit cost per linear foot. Utilities will be mapped in CADD format and converted to shp files for GIS mapping. A discussion of utilities impacts and mitigation measures will be included in the EA. Right-of-Way cost estimate for each build alternative Digital files of existing utilities Utility relocation plan and costs for each build alternative Task Cost Estimation The consultant shall develop a cost estimate for each conceptual alternative, including the No Build. The project costs will include initial estimates for right-of-way land acquisition costs, potential commercial and residential relocation costs, utility relocations costs, construction costs, environmental mitigation costs, and design engineering costs. The consultant will develop quantities for construction items associated with each build alternative and prepare construction cost estimates using current unit price costs. The consultant shall utilize recent DOTD unit bid price averages for major construction items. All minor construction items can be estimated by using contingency factors. The consultant shall note on each construction estimate that all costs are based on current year estimates for planning purposes. Approximate costs associated with engineering and surveying fees to produce future engineering plans and specifications shall be estimated for each alternative. All geotechnical investigations required for all roadway and bridge structures shall also be estimated. Construction Cost Estimate for each Build Alternative Task Construction/Maintenance of Traffic Changes to overall traffic circulation within the study area resulting from the proposed action and its effect on traffic movements and access to adjacent land uses will be described in the EA for the various build alternatives. In order to inform the public about construction impacts, the consultant will develop a conceptual plan showing the sequence and major phases of construction and how traffic flow will be maintained during construction for each build alternative. Graphics depicting the sequencing with anticipated construction duration and costs will also be prepared. Maintenance of Traffic Plan 14

15 Task Relocations Relocation impacts shall be confirmed via field surveys. A Conceptual Stage Relocation Plan shall be prepared and submitted to DOTD s Environmental Section. The Plan will include the estimated number of persons and families displaced by race, the number of persons in each family, and the approximate income level; the type of dwelling (mobile home, frame, brick) and the estimated value; the location and quality of available replacement housing and, if none is available, the estimated cost to move or build new housing; or whether any displacements have sufficient remaining land on which to move or build. The location and types of businesses to be displaced, the race of the owner, estimated number of employees by race, the number of by-passed businesses (if applicable), and a listing of available commercial buildings and sites for displaced businesses shall be identified. The Plan will also include a description of publicly-owned facilities which need to be replaced or moved, if applicable, and the existence of publicly-owned recreational sites which may be impacted. Cost estimates for relocations, displacements, right-of-way, construction costs, etc. shall be included in the document. Three (3) copies of the final Conceptual Stage Relocation Plan shall be submitted. Conceptual Stage Relocation Plan VII.
