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.

CISEC Module 3: Inspecting BMPs

This module will provide the necessary tools for inspecting BMPs found on land development, vertical/big box construction, and linear projects. Participants will learn about inspecting installed sediment and erosion control measures, whether the BMPs are functioning in a correct manner, and assess BMP limitations. In addition, information will be provided on inspecting storage areas where potential pollution problems may occur and assessing whether new BMPs need to be added or whether existing structures can be removed.

Construction Dewatering

This webinar will highlight treatment technologies that can be implemented in the construction industry to manage turbidity from dewatering operations. Dewatering methods are briefly introduced; however, the course focuses on best available technologies to treat and polish pumped effluent. Participants will be exposed to a decision matrix that assists in identifying the appropriate treatment for a site specific operation. Upon selection of the treatment, basic design elements are presented for consideration. The webinar targets a broad based audience who can use the information provided as a foundation to then independently research a specific treatment technology in more detail.

Design of Infiltration Practices: Low Impact Development Tec

This course has been developed to provide participants with the technical training required to design Low Impact Development (LID) infiltration practices and guides them through the steps of the design process. The course is intended for developers, consultants, municipalities, landowners or anyone with a general understanding of LID, looking to enhance their knowledge and learn how to design LID infiltration based practices and the process required. This course is comprised of five modules that discuss the science of infiltration, infiltration best practices, conducting a site evaluation and field reconnaissance, creating a detailed design, and the operation and maintenance of LID infiltration practices.

Designing Effective Sediment Basins using Spreadsheets

This webinar will detail the various components and requirements to develop effective sediment basin designs. The webinar will provide an overview to “SEDspread”, a (FREE) user-friendly spreadsheet-based design tool for designers to appropriately size sediment basin parameters. The workbook allows users to input site specific parameters and constraints to determine: basin capacity and configuration, surface skimmer size and dewatering rate, auxiliary spillway design, and baffle configuration. The workbook includes a summary sheet that provides users with schematics of the designed basin, available as a supplement to facilitate effective communication between designers and contractors for constructing/installing the basin.

EPA's Final 2017 Construction General Permit

In February 2017, the U.S. Environmental Protection Agency’s National Pollutant Discharge Elimination System (NPDES) Construction General Permit (CGP) will become effective. This session will provide background on construction stormwater regulations, discuss changes in the 2017 CGP, and review the process for obtaining coverage under the new permit.

From Trash To Treasure

https://www.ieca.org/images/surfacewater.gif
Description: White Island, an 80-acre former municipal landfill located in Brooklyn, New York, is one of the first grassland mitigation projects required by New York State. The former landfill was constructed on historic marsh land and exhibited severe shoreline erosion due to wave action and tidal flux. Additionally, over 80 percent of the island was dominated by invasive species. The project involved bioengineered shoreline stabilization, invasive species control, and grassland habitat creation. The project served as mitigation for the loss of 56 acres of maritime grassland habitat due to construction of a nearby Housing Development and Retail Center. The NYSDEC determined the loss of grassland habitat was a significant adverse impact on several bird species and the creation of new maritime grassland habitat on White Island was required as compensatory mitigation.

Gully Analysis and Control

Erosion and sediment control professionals are expected to recognize and understand various types of erosion, and the processes involved to effectively analyze and consider treatment options. The presentation will summarize the processes of gully formation, enlargement and effects and offer some examples of control methods applied on the Sumter National Forest in the piedmont of SC, USA. Treatments concentrated primarily on hillslope gullies which were often associated with ephemeral and intermittent streams. Gully control treatment began after the area was acquired as national forest in the 1930s, celebrated success as well as endured and learned from failure with most of the examples provided from the last 35 years.
