Port of Los Angeles Baseline Air Emissions Inventory. <br />Sensitive Receptors <br />Some land uses are considered more sensitive to air pollution than others due to the types of population <br />groups or activities involved. Sensitive population groups include children, the elderly, the acutely ill, and <br />the chronically ill, especially those with cardiorespiratory diseases. Residential areas are also considered <br />sensitive receptors to air pollution because residents (including children and the elderly) tend to be at <br />home for extended periods of time, resulting in sustained exposure to any pollutants present. Other <br />sensitive receptors include retirement facilities, hospitals, and schools. Recreational land uses are <br />considered moderately sensitive to air pollution. Although exposure periods are generally short, exercise <br />places a high demand on respiratory functions, which can be impaired by air pollution. In addition, <br />noticeable air pollution can detract from the enjoyment of recreation. Industrial, commercial, retail, and <br />office areas are considered the least sensitive to air pollution. Exposure periods are relatively short and <br />intermittent, since the majority of the workers tend to stay indoors most of the time. In addition, the <br />working population is generally the healthiest segment of the population. <br />Existing sensitive receptors proximate to the Project site include the on-site recreational facilities (i.e., the <br />Marina Park and golf courses) and the abutting residential homes to the north and east. Additionally, <br />guests of the existing hotel (The Marina Inn) may also be considered sensitive receptors. However, overall <br />exposures to TACs for the visitors to the on-site recreational facilities and guests of the hotel would be <br />relatively low and are considered short-term exposures. Unlike the exposures to TACs for nearby <br />residences, the short-term exposures to TACs for hotel and recreational use sensitive receptors would not <br />result in significant health risks. <br />Finally, students and staff of Garfield Elementary School, located approximately 1,100 feet northeast of <br />the Project site, are considered sensitive receptors. The school-based receptors are located further from <br />the Project site than the abutting residential homes to the north and east. Additionally, the exposure <br />period for school-based receptors (e.g., 8 hours per day, 5 days per week, and 180-240 days per year) are <br />much lower than for residential receptors (e.g., 24 hours per day, 7 days per week, and 350 days per year). <br />Ultimately, the overall exposures to TACs for the sensitive receptors at Garfield Elementary School would <br />PLACEWORKS 4.2-17 <br />
