Project Location Rio Ala Mano Drive Little Wekiva River State Road 434 Outfall Ditch Little Wekiva River State Road 434 Existing The project is located in Seminole County, Florida within the limits of the City of Altamonte Springs. The existing State Road 434 Outfall Ditch includes a triple box culvert and a man-made ditch stream that discharges approximately 970 feet downstream to the Little Wekiva River. It is located within a 40-foot wide right-of-way and bordered on both sides by single-family homes. Toledo Drive SR 434 Outfall Ditch FPID No. 423513-1-52-01

Project History Routine Maintenance Several Attempts Over the Past Decade to Correct/Prevent Further Erosion Previous Project (Project No. 406407-1-52-01) Constructed in 2002 Included Plantings, Erosion Control Mats, Sand-Cement Ditch Blocks, a Gabion Basket, and Rubble Rip-Rap January 2006 Removal of Overgrowth; Inclusion of Additional Sand-Cement Bags Within the past 10 years, several major maintenance activities have been performed by FDOT to correct and prevent further ditch erosion. In 2002, placement of planting materials, erosion control mats, rubble rip-rap, and construction of sand cement ditch blocks and gabion basket were done for slope protection. In 2006, removal of overgrown planting materials and garbage and inclusion of additional sand cement bags were performed. SR 434 Outfall Ditch FPID No. 423513-1-52-01

Existing Vegetation Growth Existing Conditions Ditch has Deepened, Causing Severe Bank Erosion on Both Sides Erosion is Encroaching on the Surrounding Residents’ Backyards Neighbors have Built Retaining Walls Residential Fences are Beginning to Lean and Lose Stability Ditch is Difficult for Florida Department of Transportation to Maintain Hard to Access Costly to Maintain Currently, the ditch bottom and steep side slopes experience erosion due to frequent storm events causing increased maintenance issues, potential impacts to adjacent residential properties, and long term maintenance costs to FDOT. Maintenance within the ditch is performed manually since access is very limited. Headwall at SR 434 Concrete Block Wall Existing Vegetation Growth SR 434 Outfall Ditch FPID No. 423513-1-52-01

Existing Conditions (Additional Photos) Steep Bank Slopes Active Stream Existing Fence Line Here are some additional photographs of the existing conditions at different locations within the outfall ditch.

Existing Conditions Slope Protection Provided at Various Ditch Bank Locations Gabion Basket Last Structure Prior to Discharge to Little Wekiva River Structure is Failing Primary Reason for Current Design Project The photo shown here is the gabion basket in its present condition located just upstream of the Little Wekiva River. The structure has failed and water is flowing around the structure causing slope erosion. The primary reason for the current design project is to replace this failed structure as soon as possible and protect the ditch slopes from further erosion. Please keep in mind, FDOT does not own the ditch. It is owned by the Developer – The June Realty Corporation. FDOT only has the right to use the ditch via a drainage easement to make sure water crosses under SR 434 and drains the SR 434 roadway. FDOT is just like you, a user of the ditch but willing to make the ditch better for all users of the ditch. FDOT will need your assistance and cooperation to make this project a success.

Proposed Design Improvements January 2011 Design Project Underway Install Sheet Piling to Replace Existing Drainage Structures Reduction in Soil Loss and Erosion Prevention Allows Ditch Bottom to Build Up Over Time Geotextile Improvements New Landscape/Maintenance Plan Minimization of Wetland Impacts Permitting Through St. John’s River Water Management District The Florida Department of Transportation is currently working on the following new design methodologies to address the concerns perviously mentioned. Design improvements include installing new sheet pilings to replace the four existing drainage structures, reduce soil loss and erosion, allow the ditch bottom to build back up over time, add geotextile materials to strengthen ditch slopes, and develop new landscaping and maintenance plans. The goal of this project is to perform all of these improvements with no impacts to the residents, minimal disturbance to the existing plant materials, and achieve permit approval from the St. John’s River Water Management District.

For added protection, articulating block will be placed upstream and downstream of the sheet piles. At the terminal end where the ditch meets the Little Wekiva River, new sheet pilings will also be installed longitudinally to reinforce the ditch slope and provide added protection. The following slide provides a cross sectional view of the proposed design. LEGEND: Sheet Piling Erosion Protection SR 434 Outfall Ditch FPID No. 423513-1-52-01

Proposed Design Improvements Articulating Block Articulating Block Existing Ground Line 2’ Articulating block material will be used for added erosion control protection. Geotextile material will be installed to strengthen ditch slopes. Sheet pilings will only be installed within the 40-foot wide ditch right-of-way at the locations were the existing drainage structures are currently found. The tops of the sheet pile will be capped and will follow the existing ground elevations closely. They will be embedded into the ground approximately 30-35 feet deep and 2-4 feet will be left exposed above ground. Steel Sheet Piling Geotextile SR 434 Outfall Ditch FPID No. 423513-1-52-01

Proposed Design Improvements Slope Protection – Landscape Plantings Wiregrass (Aristida stricta) Sand Cord Grass (Spartina bakeri) Pickerel Weed (Pontedaria cordata) New landscape plantings such as Wiregrass, Sand Cord Grass, and Pickerel Weed will be installed within the ditch for additional erosion control and slope protection where needed. Wiregrass Sand Cord Grass Pickerel Weed SR 434 Outfall Ditch FPID No. 423513-1-52-01

Proposed Design Improvements Slope Protection - Geotextile Material Articulating Block Articulating block will provide additional strength and stability to the steep slopes. This material will be placed immediately upstream and downstream of each sheet piling location. Articulating Block Samples SR 434 Outfall Ditch FPID No. 423513-1-52-01

Proposed Challenges Access Access from State Road 434 Potential Access via Existing Easements Construction Equipment Construction Material Delivery Current access to all residential properties will be maintained. Essentially this means existing traffic patterns will not be affected and existing driveways will remain open during and after construction. Construction equipment will access the project site from State Road 434. Construction materials will be delivered to the site from State Road 434 and existing easements.

We Want Your Input Please Turn in the Comments Cards Tonight Mail the completed card by May 29, 2011 Comment Cards are provided if you would like to make a comment or question and become a part of the project file. Please place your comment cards at the sign in table near the doorway or mail them to the contact listed on the card by May 29, 2011. I would like to stress the importance of receiving your input on how we (the users of this ditch) can work together to make things better. For example, we will need the owners cooperation on how we can address the encroachments such as fences that will prohibit construction and to put back the fences at the right property lines. We will also need to address harmonizing the properties if the flow of water has adjusted the ditch beyond The June Realty’s ditch boundary line. We welcome your comments and input to make this project a true success. SR 434 Outfall Ditch FPID No. 423513-1-52-01
