• Developing a GIS Framework to Identify Acquisition Cost-effective Structures of a Floodplain
  Kaveh Zomorodi, Ph.D.
  Dewberry, Fairfax, VA
  Presented at the Association of Floodplain Managers Annual Conference
  May 2003
  We are developing a GIS framework for quick-automated identification and mapping of the cost-effective structures within a floodplain. The new framework consists of two components. The first component is a simplified BCA method that allows decision-making about cost-effectiveness of each structure and the second component is a GIS application that overlays an Enhanced DFIRM and a DTM of the area and performs the required calculations and produces maps of the results. The first component is already intact and functional and has been verified by extensive testing. Development and of the second component, the GIS interface, is underway. A brief description of this methodology is described in this paper.

  Hurricanes, Nor’easters, winter storms and tsunamis cause damaging and destructive inundation of coastal areas. The development and implementation of numerical models allows natural events to be replicated so that their potential effect can be known and lives and property protected. Although a brief overview of the numerical characteristics of each model is provided in this paper, the paper aims to highlight their function and application as forecasting, planning, warning and monitoring tools, while detailing the chronological development of coastal inundation models.

  David F. Maune, Ph.D., CP, CFM
  Senior Project Manager
  Proceedings of the Fall 2003 Conference of the American Society for Photogrammetry & Remote Sensing
  October 2003
  Why is it that states and counties often advertise for LIDAR data for diverse applications, but then specify that the data must satisfy requirements of the Federal Emergency Management Agency (FEMA)? What are those FEMA requirements, and why are they sometimes considered as the de facto industry standard for LIDAR? Does FEMA mandate the use of LIDAR, or can other means of ground and/or aerial surveys be used? This paper answers these questions and explains FEMA's standards for digital elevation data regardless of whether requirements are satisfied by LIDAR or other technologies such as photogrammetry or IFSAR.

  David F. Maune, Ph.D., CP, CFM, Dewberry

  May 2000

  Light Detection and Ranging (LIDAR) and Interferometric Synthetic Aperture Radar (IFSAR) have recently become the technologies of choice in mass production of Digital Elevation Models (DEMs), Digital Terrain Models (DTMs), and Triangulated Irregular Networks (TINs), referred to generically hereafter as DEMs. This paper presents lessons learned from LIDAR projects to date in various states. It addresses opportunities presented by LIDAR and IFSAR for generating DEMs as articulated by various user groups in the National Height Modernization Study. Finally, it summarizes actions required by the remote sensing community to establish LIDAR and IFSAR as standard tools, with established standards, for generating digital elevation data for the new millennium.

• HVAC: Better Cooling Choices — Cheaper, Too
  Russell James, President, TOLK (A Dewberry company)
  Building Operating Management magazine
  March 2003
  Conventional wisdom often tends to lead owners, contractors, and designers down the same path when it comes to HVAC system design. Many owners still believe that they must spend more in first costs to achieve higher efficiency and superior HVAC system results. But rather than focus on the individual pieces of HVAC equipment — and the price tag that comes with each component — there are often significant benefits to building owners and occupants when engineers explore an overall systematic approach to HVAC design. An initial investment of time in the early stages of design, along with the application of a few basic fundamentals, can yield superior HVAC systems at a lower overall first cost — without sacrificing quality.

  The existing three span bridges over the canals on East Pine Street in the City of Long Beach, NY, were rehabilitated to single-span bridges. To achieve this, a number of obstacles were overcome, including procuring funding, meeting headroom restrictions for marine traffic, allowing for grade change limits for road users, abandoning of the initial precast concrete segmental design at 95% completion, fast tracking design on a new alternative to meet fiscal deadlines, and developing a three-dimensional model to ensure that the load transfer between members satisfied deflection limits.

• Low Impact Development: Integrated Management Practices and Policies
  William S. Springer, PE
  Presented at the Association of Floodplain Managers Annual Conference
  May 2003
  Low-impact development (LID) is a relatively new process whereby engineers and site developers implement ways to help reduce peak runoff from a site and improve post-construction water quality conditions. LID promotes trying to duplicate the pre-developed hydrologic pattern of a watershed by providing a series of integrated management practices, such as reducing impervious areas, disconnecting standard drainage systems, and creating many small areas of ponding and water quality enhancements as opposed to a single stormwater management basin in the lower part of the watershed.

 

• Quantifying Groundwater Recharge From Detention Basins To Forested Buffers In New Jersey
  Kaveh Zomorodi, Ph.D.
  Dewberry, Fairfax, VA
  2003
  The New Jersey stormwater management regulations require the post-development annual groundwater recharge volumes match those of the pre-development conditions. In parts of New Jersey, field observations have shown that most or all of the water released at low discharge rates from detention basins to forested buffers infiltrate into the soil within a short distance. However, there are no computational tools available to quantify the volume of the annual groundwater recharge expected from this practice. This study was conducted to develop a general solution methodology.
