to an unusual rainstorm falling in the area. The Hill Fire and Woolsey Fire were separate fires which began within 23 minutes of one another on November 8, 2018. Both threatened many homes in Newbury Park, and while the Hill Fire was contained fairly quickly, the Woolsey fire rapidly got worse and destroyed large areas of southern California. Most of Newbury Park was evacuated for 2–3 days during these fires. Local schools were closed for 2 weeks, for the purpose of repair of smoke damage. No structures in Newbury Park were lost, partially due to aggressive firefighting, and also due to previous burn from the 2013 Springs Fire stopping the spread in that direction. These fires started just 15 hours after the mass shooting at the Borderline Bar and Grill, thus making it the most difficult day in the city's history. Newbury Park was also affected by the massive Thomas Fire of December 2017, and a smoke advisory was issued by the Ventura County Air Pollution Control District. Subsequently, all public schools were closed on December 6, 2017. An additional 3-acre brush fire, nicknamed the Runner Fire, broke out behind the headquarters of Amgen and Shire (Baxalta) on December 5. Both Amgen and nearby SAGE Publishing decided to evacuate their employees due to thick smoke. The fire had a potential of reaching Hill Canyon due to the warm Santa Ana winds, but was contained before causing major damage or injuries. Geology Newbury Park is the westernmost community in the Conejo Valley, which is located in southern Ventura County. It is a broad, wide, and high-lying incline, with an average elevation of 900 feet above sea level. It is bordered by the steep ridge-lines of the Santa Monica Mountains to the south and southeast, Conejo Mountains to the west and north (including the Conejo Grade in westernmost Newbury Park), and the Simi Hills to the northeast. While the Oxnard Plain and the community of Camarillo are immediately to the west, the Santa Rosa Valley is beyond the Conejo Mountains or through Hill Canyon to the north. Beyond the Santa Monica's to the south is the Pacific Ocean, while the San Fernando Valley is beyond the valley's eastern ridges. The physiography is characterized by open vistas, high peaks, creeks and creek-beds, prominent knolls, and native oak woodlands. Along with the Santa Rosa-, Tierra Rejada- and Simi Valleys, the Conejo Valley is also
