Task 1.1 Code Research: The goal of code research is to find the federal, state, and county codes and regulations for the design of channel and culvert.
Task 1.2 Research Existing Topography: Maps from USGS will be used to identify the topography in the area.
Task 1.3 Review Existing Plans/Studies: Plans and proposals for the site will be requested from the City of Flagstaff to compare the data obtained from the survey and prevent any errors in the topography.
Task 1.4 FEMA Floodplain Research: The data from FEMA and regulatory floodways will be examined in relevance to the project region and evaluated based on results.
Task 2.1 Site Visit: A site visit is required for documentation of conditions and data points of topography in a field survey.
Task 2.2 Topographic Map Documentation: The data collected from the site investigation will be used for an analysis of the initial conditions and will be input into a drawing on AutoCAD. The first drawing will give information about existing structures and the topography of the area.
Task 3.1 Watershed Delineation: An accurate map of the project watershed will need to be delineated and shown properly for hydrologic analysis.
Task 3.2 Time of Concentration: The time of concentration for the water flowing into the problem area will be determined in order to calculate other factors of analysis such as rainfall intensity and runoff.
Task 3.3 Determine Rainfall Intensity: NOAA Atlas 14 will be used to determine the intensity based on the time of concentration and design storm.
Task 3.4 Determine Runoff: The amount of volume that is going through the system will need to be determined.
Task 4.1 Open Channel Analysis: The current open channel design will be analyzed using the plan obtained and thorough the site investigation. As well as analyzing the channel characteristics like material, shape, and size to determine how it affects the capacity of the channel. FlowMaster or HEC-RAS will be used to find the normal depth, velocity, and flow regime.
Task 4.2 Culvert Analysis: The culvert material, shape, size (length and diameter), and slope will be determined using the images and observation from the site visit. After determining the culvert data, CulvertMaster will be used to determine the peak discharge.
Task 5.1 Identify Constraints and Criteria: The constraints and criteria will be determined before beginning the design part of the project.
Task 5.2 Develop Design Alternatives: Different designs will be drawn in AutoCAD while also identifying/analyzing their weaknesses and strengths to select the best design.
Task 5.3 Select Best Alternatives: Using parameters like efficiency, cost, and materials, the selected designs will be analyzed. Using the decision matrix, scores will be given to each design and the design with the highest score will be chosen.
Task 6.1 Construction Plans: The best design chosen from the decision matrix will be a fully developed construction plan.
Task 6.1.1 Cover Sheet: A cover Sheet for the Auto-CAD design will be created.
Task 6.1.2 Profile Views: The elevation view of each portion of the wash will be covered and annotated in detail.
Task 6.1.3 Cross-Section Views: A cross-section drawing of the culvert will be created to show the internal structure of the design.
Task 6.1.4 Details Sheet and General Notes: A details page will be used discussing all the codes and justifications for design features within the drawing.
Task 6.1.5 Extra Sheets: Other sheets may be needed to accurately plan out the construction plans.
An impacts analysis will be completed to determine the positive and negative environmental, economic, and social impacts of the design.
Task 9.1 30% Submittal: The 30% submittal will include tasks 1 and 2 (research and site investigation) to include the surveying of the area and the research behind the project to give a full scope of what is to come. Within the 30% submittal will be a presentation, design report, and project plans.
Task 9.2 60% Submittal: In the 60% submittal, tasks 3, 4 and 5 (hydrologic and hydraulic analysis) will be done to understand the scope of the water analysis and water design. Everything that is required to be analyzed for the water properties/behaviors will be completed and included in the 60% report. Within this 60% submittal will be a presentation, design report, and project plans.
Task 9.3 90% Submittal: The 90% submittal will include tasks 6 and 7 (AutoCAD plans and impact analysis) within the report to show the design of the project and the impact the project has on the general public and wildlife. The submittal will include a plan set as well as the design report for client viewing. The project website will be mostly complete with documentation uploaded.
Task 9.4 Final Submittal: The final report, plans, and presentation will be presented to the board and to the client for consideration and any comments they may have. The website will also be complete for public viewing at the final submittal.
Task 10.1 Meetings: These meetings will consist of Technical Advisor meetings, Grading Instructor Meetings, Client meetings, and Team meetings.
Task 10.2 Schedule Management: The schedule will be tracked and updated to ensure that the project will be completed on time.
Task 10.3 Resource Management: Staffing and budgeting of the project will be managed to ensure the project is completed on budget.
