Project Information

PROJECT DESCRIPTION

The Aqua Jacks Team is evaluating the feasibility of stormwater capacity and stabilization within the Smokerise neighborhood of Flagstaff, Arizona.

An evaluation of the surrounding watershed runoff with seasonal rainfall and snow melt will be conducted against existing infrastructure to identify preliminary design alternatives. Designed improvements through hydraulic, hydrological analyses will comply with appropriate local, state, and federal regulations.

Improvements in the Smokerise neighborhood should mitigate preventable flooding risks and long-term stormwater goals for the City of Flagstaff.

Stormwater currently enters the neighborhood through culverts crossing the US-89 from Penstock Wash. Smokerise in our project focus area relies moderately on surface street runoff capacity to funnel into the existing, concrete open channel of the neighborhood.

Agua Jacks is focusing their project work on the area closest to the U.S. Forest Service municipal building where hydraulic and hydrologic improvements can be made. This project focus works best for the team when taking into consideration semester time limitations.

PROJECT TASKS

Task 4.3: Deficiency Identification: Deficiencies will be identified from culvert and channel analysis using appropriate municipal standards.

Task 5

Task 5.1: Identify Constraints and Criteria: Development of constraints will come from assigning structured values based on the criteria of the project.
Task 5.2: Develop Alternatives: Alternative designs for the project area will be created based off of identified constraints and criteria.
Task 5.3: Select Best Alternatives: Alternatives will be ranked based on a decision matrix with quantitative and qualitative metrics.

Task 6

Task 6.1: Final Hydraulic Design: Final hydraulic design will include detailed modeling and sizing of the selected alternative design for the 10-year and 100-year storm events.
Task 6.2: Plan Set Creation: Preparation of construction-detailed drawings such as plan, profile, and typical sheets.

Task 6.2.1: Cover Sheet/Existing Site Plan
►

Task 6.2.2: Proposed Site Plan
►

Task 6.2.3: Detailed Design Drawings

Task 6.3: Construction Cost Estimate: An engineer's opinion of probable construction cost will be developed based on proposed materials, design quantities, and regional pricing.

Task 7

Impacts analysis will evaluated the broader implications of the Smokerise project on the greater area of Flagstaff, Arizona.
Economic, community, and local impacts. Both environmental, and global.
Enhances quality of life for Smokerise neighborhood residents.

Task 8

Task 8.1: 30% Deliverables
Task 8.2: 60% Deliverables
Task 8.3: 90% Deliverables
Task 8.4: Final Deliverables

Task 9

Task 9.1: Schedule Management: The project schedule will be maintained and regularly updated in Microsoft Project to monitor task progress, dependencies, and milestones.
Task 9.2: Resource & Budge Management: Staffing and resource allocation will be managed to balance workloads and maintain productivity.
Task 9.3: Meetings & Quality Assurance: Meetings will be held regular with the team, client, technical advisor, and instructor to ensure quality assurance and peer reviews.

GANTT CHART

The Agua Jacks team will utilize a Gantt chart to organize tasks and time for the team to ensure project tasks are completed on time. Critical tasks are highlighted in red with non-critical tasks highlighted in blue.

PROJECT CONSTRAINTS

Identification of project constraints will be conducted by defining the criteria to be met with assigned weight factors. Criteria will be established through the project requirements such as cost, maintenance, performance, and feasibility. Requirements will be assigned a weight value in a decision matrix to identify the best design alternatives.

Easily identifiable constraints are comprised of but not limited to: avoiding private property, realistic budget, time limitations, and technical abilities.

STAFFING PLAN

The Agua Jacks team is using a staffing plan that organizes the team's structure and responsibilities. Tasks and responsibilities will be split amongst four team members. Four positions that are identified for our team are the principal engineering (PE), project engineer (PrE), engineer-in-training (EIT), and an intern (INT).

Principal Engineer: Civil/Environmental PE, 5-10 years.
Project Engineer: Civil/Environmental PE, 2-5 years.
Engineer-in-Training: Passed Civil/Environmental FE, 0-2 years.
Intern: Pursuing Civil/Environmental BS Degree

It is recommended that the team is compromised with at least one civil and environmental engineer.
