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?
