Sustainable Design Principles Specifically related to stormwater, a sustainable project can be defined as a project that provides a balanced benefit to the community and the environment while being economically feasible in the present and future. A sustainable stormwater management project strives to provide recreational opportunity, habitat creation/preservation, flood control, water quality improvement, and long term maintenance plans with adequate funding and staffing....

What is a SSWAP? A SSWAP applies sustainability to stormwater management practices for development and redevelopment to improve the water quality of waterways within a community. A SSWAP offers substantial benefits to the community and environment through reducing maintenance burdens, addressing flooding and erosion problems through best management practices, and protecting and restoring watershed health.

Getting the Ball Rolling in your Community Stormwater management is a critical piece of the...

Data Model The Arc Hydro data model was developed to transition hydrologic modeling from an inventory-based data model to a behavioral model, established on the relationship between various hydrologic data sets. Arc Hydro has been adopted as the water resources industry standard geodatabase structure or “schema” and is comprised of five major data types: drainage features, geometric flow network, hydrography, channel description and time series. The relationships between the layers are determined by...

How Does It Work? Generally, a 1-D hydraulic engine is used to model flow through storm sewers or channels, and the 2-D hydraulic engine is used to model the overland flow that occurs when the drainage system capacity is exceeded. However, the results from a 2-D model are only as good as the data used to build the surface model. So, the first requirement for 2-D modeling is an accurate surface model that...

Dallas wants to be the leader of major U.S. cities when it comes to protecting the environment. The City has already adopted one of the most progressive green building ordinances to address the design of structures, and now Freese and Nichols is working with Dallas to implement the Integrated Stormwater Management Design Manual for Site Development (iSWM) to better handle stormwater runoff from the land around those buildings.

Future Development City leaders...

As part of the firm’s Bee Cave Parkway project, Freese and Nichols designed a two-span pedestrian and cyclist crossing under Bee Cave Parkway and alongside Freitag Creek to provide access to the city park. Throughout the project, keeping close to Freitag Creek’s natural features was crucial to the City.

Innovative Creek Crossing under Bee Cave Parkway Freese and Nichols innovatively designed Freitag Creek’s two-span pedestrian crossing under Bee Cave Parkway as a...

Traditional planning and design of stormwater management systems focuses on minimizing construction costs and maximizing developable land. Decades of using the traditional method and micro-designing stormwater management systems has created a chaotic network of pocket detention ponds and stressed pipe and channel systems, which municipalities are struggling to obtain sufficient funding to repair. The impacts on these systems are further exacerbated by increases in projected population...

United States in a Stormwater Funding Crisis According to Steve Allbee of the U.S. Environmental Protection Agency, our nation is underfunding necessary stormwater, wastewater and water infrastructure improvements by at least $540 billion. Considering that most cities typically maintain only water and wastewater utility funding sources, this nationwide funding deficit is particularly alarming for those of us in stormwater management.
