INVENTORY OF EXISTING CONDITIONS »Hydrophytic Plants: a preponderance of plants adapted to wet conditions; and »Hydric Soils: soil developed under wet conditions. A wetlands inventory was conducted over the course of eight days between April 27 and May 12, 2016 on Airport property Approximately 2,325 acres of Airport property and City-owned property adjacent to the Airport were surveyed (see Figure 1-20). Wetlands were identified during the site survey and mapped for future development considerations, but no jurisdiction determinations were made for the identified wetlands. Approximately 453 acres of wetlands were identified within the study area (see Figure 1-20). 1.13.14.2 Floodplains Statutes and EOs that are relevant to floodplains include: »EO 11988, Floodplain Management (42 FR 26951); »National Flood Insurance Act (42 U.S.C. § 4001 et seq.); and »U.S. Department of Transportation (USDOT) Order 5650.2, Floodplain Management and Protection. Floodplains are “...lowland areas adjoining inland and coastal water which are periodically inundated by 37 flood waters, including flood-prone area of offshore islands.” Floodplains are often referred to in terms of the 100-year floodplain, rather, the one percent chance of a flood occurring in any given year. EO 11988 directs federal agencies to take action to reduce the risk of flood loss; minimize the impact of floods on human safety, health, and welfare; and restore and preserve the natural and beneficial floodplains. EO 11988 does not allow activities in a floodplain unless there is no practicable alternative and there are measures to minimize unavoidable short-term and long-term impacts are included. USDOT Order 5650.2 outlines the policies and procedures for ensuring that proper consideration is given to the avoidance and mitigation of adverse floodplain impacts in agency actions, planning programs, and budget requests. Therefore, the objective is to avoid, to the extent practicable, any impacts within the 100-year floodplain. According to the current Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps for 38 the Airport area, there are floodplains within the Airport property. The floodplains are located in the southern and northeastern portions of the Airport property boundary (see Figure 1-21.) 37 Executive Order 11988, Floodplain Management, May 1, 1977.
