CEDARVILLE Engineering Group, LLC (CEG) was tasked with creating a 3D Model to be used in the design a green stormwater infrastructure retrofit project for this 11+ acre historical penitentiary. Site design requires topographical features be surveyed with accuracy and precision. This site was more complex than usual due to the variety of surfaces constructed through history, and the unmapped network of underground infrastructure beneath the site.

Survey control was established with a robotic instrument and supplemented with conventional survey. CEG’s drone (sUAS) pilot flew NADIR and two oblique flights. Ground based capture was also completed using a handheld camera with a 10mm lens.

Using 3D Modeling, all data sets were combined to create one overall 3D model. With this model, CEG could extract information to create a “Site Characterization Plan” for the client.

The client now has a long-term view of the property that is being used to design stormwater management and the construction of a new visitor’s center to accommodate tourists. The model provides detailed accuracy of the site from both an aerial and surface level perspective. As the historical site undergoes renovation updates can easily be made to the model without the entire survey having to recreate the survey from scratch.

CEDARVILLE Engineering Group, LLC (CEG) has supported Towson University by conducting multiple studies on Asset Management, Public Education and Outreach and Stormwater Permitting. Asset Management.

CEG conducted a stormwater infrastructure field verification of existing structures to provide the basis for the integration of a new GIS based stormwater mapping system. Each structure was documented, and GIS data and photographs provided. Evaluated the condition of each stormwater structure and developed a schedule for short-term and long-term maintenance and repairs. This effort provided a framework for the University’s stormwater asset management program, increasing efficiency by enhancing planning efforts and reducing costs.

CEG performed field verification of stormwater assets on the TU campus in the fall of 2016. A stormwater infrastructure map was created that listed all the University’s storm pipes, structures, outfalls, and BMPS. One outcome of that work revealed that certain stormwater conveyance structures (pipes and culverts) are in imminent need of repair.

CEG performed a desktop evaluation of the stormwater assets and assigned a conditional ranking to each structure based upon its need for repair and/or replacement. CEG prioritized assets in need of immediate action (0 to 6 months), those needing certain action (one to two years), and those where maintenance or future repairs should be budgeted (2 to 5 years). A written report of findings included cost estimates for the recommended repairs/replacement, and the priority assessment of the repair/replacement work.

New Orleans is located in a low-lying area just above, at, or below sea level.  There is an extensive pump system that pumps stormwater collected from canals during storm events and seepage from the surrounding surface water bodies recharging the groundwater table to Lake Pontchartrain; inevitably this water makes its way back towards New Orleans, only to be pumped again. This constant pumping has led to subsidence.

Disconnecting and redirecting portions of stormwater flows from the canals and pumps in New Orleans would reduce the amount of water entering the pump system and may reduce the rate of subsidence in New Orleans.  Based on the soil conditions encountered and the stormwater flows that are present within each sub-watershed, there would be a variety of stormwater Best Management Practices (BMPs) for managing stormwater.

Managing stormwater requires a decentralized approach.  While there may be consistent site conditions within a neighborhood and one type of BMP may be appropriate, in general the site conditions determine the BMP type.  Depending on the site conditions, a stormwater BMP may provide recharge (e.g. infiltration bed), attenuation and storage (e.g. traditional detention basin), or filtration (created wetland).  Each BMP would require a specific type of operation and maintenance to ensure the long-term performance of the particular facility. 

CEDARVILLE Engineering Group, LLC (CEG) manages and facilitates the Stormwater Management Program for municipalities for compliance with their Department of Environmental Protection (DEP) NPDES MS4 permit.

Examples of specific results include:

• In Westtown Township, we reviewed the existing mapping, identified proposed BMPs which would meet the requirements of the TMDL, and provided cost estimates for the construction of each BMP.
• In West Norriton Township, we developed a comprehensive Township-wide GIS inventory of stormwater infrastructure and maintains this database in-house.
• In East Brandywine Township, Best Management Practices (BMPs) were proposed and calculated to maximize pollutant load reductions and minimize cost to the Township.

CEG also provides design and feasibility studies for the implementation of the TMDL and Pollutant Reduction Plans.
