Dunleith Lane Background
What is Dunleith Lane? Mandeville, Louisiana Small subdivision
History 2000- Drainage System and Road
constructed 2004- First houses completed construction Present- Long standing drainage issues
Objective
To understand what the drainage problem is on Dunleith Lane
Once the problem is fully understood, formulate the most cost efficient way to correct the problem
Overall Vision
Correct the drainage issue on Dunleith Lane
Reduce the amount of standing water in the ditches after storms
Prevent any flooding from happening in the yards of occupants
Timeline (1st Semester)
10/8- Proposal/Power Point 10/13- Receive Permission from Homeowners 10/19- If possible receive any existing drawings of the
land 10/27-Take detailed pictures of area 11/2-Measure Dimensions of neighborhood 11/10-Create Preliminary drawings with dimension 11/17-Survey the Area 11/24-Analysis of the collected data/establish
problem 12/5- Complete final presentation (first semester)
Deliverables (Fall 2014)
Through the use of surveying equipment and knowledge, we were able to understand and evaluate the drainage issue
Drafting was also required in order to get the drawing on paper with proper dimensions and elevations applied
Surveying Methodology
We used a transit, surveying tripod, and surveying rod to take shots of the height above the ground at certain points
We were then able to transfer these shots in to elevations that allowed us to understand the flow of the system
We were also required to calculate slopes between two points given the elevations
Drafting Methodology
We were required to create two sets of drawings Preliminary field drawings that we brought
out with us to record our shots Final drawings that show the elevations
throughout the system (existing conditions)
Problem Areas
Ditches in front yards Ditches in backyards City Drainage/Main Culvert exiting
Dunleith Lane
Ditches in Front Yards
Low spots in some areas do not allow water to flow throughout the interior of the neighborhood
Erosion has taken place and a lot of the system has flattened out over time
Plan View (Ditches in Front Yards)
Ditches in Back Yards
The ditch that runs behind the backyards of several occupants also holds water after rainfall
Water should flow out to the city drainage over time, however, the drainage is so slow that it is causing major backups in the system
The woods behind the yards have overgrown in to the ditches, also likely adding to blockage
Plan View (Ditches in Back Yard)
Culvert System/City Drainage The point where Dunleith Lane connects to the city is
extremely low Over time, the water draining out of the neighborhood has
created an extremely low spot in the city drainage right where the two meet
Culvert System/City (Plan View)
Next Semester
Re-Evaluate all existing issues in the system Devise at least two methods which will allow
us to correct the issues Estimate cost of each method Decide which method most suits the cost
requirements and functionality of the system Create a schedule for the project Present to the Home Owner’s Association?
