From page 28... ... In part, this is because water resource issue management is frequently not considered to be an integral part of the development project planning process. This results in the tendency to manage water resource issues associated with development projects on an ad hoc basis in which issues are addressed as they arise. Read the entire page →
From page 29... ... The Water Resource Issue Management Plan establishes the guiding principles, management structure, methods, and strategies that will be used to execute the management of water resource issues within the context of a development project. Documentation of findings during development of the Water Resource Issue Management Plan development is important. Read the entire page →

From page 31... ... A well-conceived inventory provides the following benefits: • Data for better informed initial siting and layout decisionmaking during the Conceptual Planning Phase; • Information for initial discussions with regulators; • Information to support the NEPA process; • A common reference point for assessing water resources on multiple projects; • Information with documented sources and levels of accuracy to provide more representative comparisons of potential impacts for multiple projects; • Cost savings by avoiding the need to reassess water resources on a project-by-project basis; • Reductions in schedule impacts during early planning by potentially avoiding a data consolidation and collection step; and • Reductions in negative impacts to the development project function, airport operations associated with the development project, project schedule, and project costs resulting from decisions made using insufficient water resource data. The information contained in an inventory may vary depending on the water resources and local regulatory conditions, but generally should include the following, as available: • Maps showing general locations of the various resources, including – Wetland inventory maps (jurisdictional and non-jurisdictional) Read the entire page →
From page 32... ... • Adjoining community or other land use plans. • Supporting information that may not specifically be a water resource, but supports assessment of water resources – Topographical maps, – Land use maps for the airport and adjoining communities, – Storm water infrastructure drawings, – Deicer use records and deicer application locations, – Water quality data, and – Water quantity data.

From page 33... ... An airport may find that establishing methods for tracking development project life-cycle costs on projects, specific to cost impacts from water resource issue management, strengthens the ability to demonstrate the benefit of early planning for water resource issues on future projects. Such a tracking system can certainly be a challenge to implement, but may be beneficial for airports with many planned development projects. Read the entire page →
From page 34... ... From a water resource issue perspective, however, both projects may require a large amount of new impervious surface to be constructed on previously undeveloped land. Thus, both projects may have similar water resource impacts and water resource issues to manage, such as filling of wetlands, increases in storm water quantities, and impacts to water quality.

From page 36... ... The regulations define the processes used by airports and regulations to assess water resource impacts and how mitigation for impacts must be addressed.

From page 42... ... In the Water Resource Issue Management Plan, the basic approach to NEPA at the airport should be documented, along with key considerations to decide at the start of the planning process for individual projects. 42 A Handbook for Addressing Water Resource Issues Affecting Airport Development Planning Key Notes The project management team must define -- in coordination with regulators -- when permitting for individual water resource issues will occur relative to the schedule for the NEPA process.

From page 43... ... The approach is based on the following elements: • Having sufficiently comprehensive and accurate information on which decisions are based; • Understanding the continual feeding of information back and forth between the water resource issue assessment and development project implementation; • Needing to understand compliance concepts independently for individual water resource issues; and • Grasping the importance of consolidating the effects of complying with multiple water resource issues on development projects. As part of the Water Resource Issue Management Plan, it is recommended that the guiding principles and execution methods for managing the individual water resource issues be defined.
