Building Green: Atlanta's Green Infrastructure Approach

The City of Atlanta has embraced the use of green infrastructure as a means of combined sewer capacity relief, ecosystem restoration, economic stimulus, and water quality control. In February of 2013, Atlanta adopted one of the most far-reaching stormwater management ordinances in the country.Ê The ordinance helped lay the groundwork for a robust green infrastructure program, both for private development as well as capital improvement projects undertaken by the City.Ê To date, the City has permitted over 2,000 construction projects that utilize green infrastructure to reduce the volume of polluted runoff. ÊIn addition, the City is currently installing the largest permeable paver roadway project in North America - six miles - to help alleviate flooding in neighborhoods served by the City’s combined sewer infrastructure.

Changing the Development Paradigm to Embrace LID - Part 1

The Problem with Conventional Development & Stormwater Management: This webinar will investigate and demonstrate the many impacts, associated with our current approach of prescriptive land use policies and stormwater management that have led to adverse impacts to our natural environment, particularly aquatic systems due to “the law of unintended consequences” of these policies. The webinar will also introduce attendees to the concept of Low Impact Development (LID) which is a paradigm shift in how development and stormwater is done to minimize the impacts of development on the natural environment. A history of LID will be provided as well as a discussion of how LID works and why it is a much better approach for land development projects.

Changing the Development Paradigm to Embrace LID - Part One

The Problem with Conventional Development & Stormwater Management: This webinar will investigate and demonstrate the many impacts, associated with our current approach of prescriptive land use policies and stormwater management that have led to adverse impacts to our natural environment, particularly aquatic systems due to “the law of unintended consequences” of these policies. The webinar will also introduce attendees to the concept of Low Impact Development (LID) which is a paradigm shift in how development and stormwater is done to minimize the impacts of development on the natural environment. A history of LID will be provided as well as a discussion of how LID works and why it is a much better approach for land development projects. The Basis of Low Impact Development: In this webinar attendees will learn about the most important aspect of Low Impact Development (LID), Environmental Site Design (ESD). ESD is the cornerstone of the LID approach by evaluating the natural resources on the site and placing the development on the land which is most suitable for it. The natural environment provides many positive benefits especially related to the rainfall runoff relationship. These many benefits will be discussed and it will be demonstrated how the application of ESD for residential development can preserve many of these benefits, while at the same time mimic the natural hydrologic relationship for small, frequent rainfall events. The common hydrologic goals associated with LID will also be discussed and it will be shown how ESD can help a designer meet these goals. In addition to the hydrologic benefits of ESD, the preservation of woodlands and meadows also provide other environmental benefits such as the sequestering of carbon.

Connecting With Stakeholders for Stormwater Success

https://www.ieca.org/images/ErosionandSedimentControl.gif
Description: Short and long-term successes of stormwater programs are built on planning, design, engineering and stakeholder support among other critical elements. Building a network of stormwater advocates is important for public acceptance and understanding of how stormwater impacts water resources. There are several levels of engagement and involvement that depend on stakeholder interest, understanding and time availability. Stakeholder motivations, learning styles, and program options are all part of the overall engagement process. This presentation will describe lessons learned working with community stakeholders to build awareness and involvement in stormwater management.

Construction Site Erosion and Sediment Control: Best Practices and Low Impact Solutions

Often construction-phase and post-construction stormwater management are separate worlds (different permits, different plans, different practices, etc.); however, in terms of hydrology, water quality and the ultimate success or failure of post-construction practices, they are closely related. This webinar will briefly review stormwater regulations for construction and post-construction and will explain how hydrology is a unifying theme. The webinar will include state-of-the-practice details for common LID and GI practices and will focus on details that are important to pay attention to during construction for successful stormwater quality management for the long term.

Ecological Monitoring for Construction

While monitoring and management of protected adjacent wetland features is a common condition of most anthropogenic activity approvals, no standard method for such work currently exists in Canada on a national (or provincial) level. Ecological monitoring methods open vary between sites depending on the preferred methods of the body conducting the work, and/or associated regulatory agencies. Consequently, the absence of standardization for ecological monitoring results in wide-ranging interpretation, development, implementation and quality of monitoring plans which in turn creates a “grey area” when it comes to consistency, compliance and accountability. What can you do to make sure you are working in compliance when there is no standard?

Implementing a SWPPP - Easy, right?

The design is complete, the permits have been obtained, and contracts are in place for contractors. It's time to get construction started! What could possibly go wrong? A SWPPP, stormwater pollution prevention plan, is a best guess about how the construction site will begin, progress and finish based upon the information that the design has before construction. However, it is rare that construction progresses as the designer envisioned. When implementing a SWPPP, expect to encounter the following: - The contractor will have a different - and possibly better - way of grading the site, along with a different construction sequence. - The unforeseen will be uncovered and it will impact the construction schedule. - Not all parties on the construction site will agree on E&SC or stormwater management for the site. When implementing the SWPPP, the inspector/site manager must adapt to these issues while still meeting the intent of all permits. SWPPP modifications. There is no perfect SWPPP. All SWPPPs will need revision and modification during construction. Some states do not require that plans be resubmitted when modifications are required. Other states do require plan submittal and approval. Know your state's requirements - and any professional requirements. In most states, professional engineers are the only people licensed to design pipes and embankments (think sediment basins and culverts). The SWPPP must reflect what's on the ground and vice versa. For example, when silt fence or check dams are removed when they are no longer needed, the SWPPP should be modified to show that these measures have been removed. Inspection documentation should also indicate that the measures have been removed and why they were removed. Together, the modified SWPPP and inspection documentation should clearly tell the story of the site conditions at the time of the inspections. Take photos of the site as well to confirm site conditions. Documentation. As the SWPPP is revised or modified, document the changes on the SWPPP sheets, in inspection reports and with photos. Documentation is critical to show compliance. The construction general permit allows time for a contractor/developer to respond to problems found on a construction site, and if the problems are resolved within that timeframe, the site is in compliance. Note that some states have additional regulations governing construction sites and off-site sedimentation can be considered a violation of the regulation, regardless of storm size. Besides SWPPP modification and inspection reports, a site manager/inspector must also keep good documentation of rain events. The Construction General Permit requires that measures be designed for the 2yr, 24hr rain event. To determine the return interval for each storm, document the time a storm started and ended and the depth of rain. That information can be compared to rainfall information provided on NOAA's Atlas 14 Point Precipitation Frequency Estimates website (https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html) to determine the storm's return interval. Site managers/inspectors should use the rainfall data to make decisions about the failed measures. If measures failed in a storm that exceeded the 2 year storm equivalent intensity, the measures were adequate and should be reinstalled. If measures failed in a storm that was less than or equal to the 2 year storm event, the measures should be upgraded. can be compared to the rain fall information on NOAA's Atlas 13 site to determine the equivalent intensity storm. As a final good practice on a construction site, provide feedback to the designer about the site: what worked well, what didn't work well. If that information is not conveyed to the designer, the same issues may occur on other construction sites.
