DUNLEITH LANE DRAINAGE SYSTEM Justin Lyle and Cody Binder ET 493- Senior Design Advisor: Mohamed Zeidan Construction ET 10/08/2014

Dunleith Lane Background  What is Dunleith Lane?  Mandeville, Louisiana  Small subdivision  History  Drainage System and Road constructed  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 (1 st 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?
