OH Brodie, Redlands, Daily Facts, 24 Jan 1975, p. 3 - Nearly complete master plan Storm drains...
Nearly complete master plan Storm drains charted for Redlands environs lakes by the San Bernardino Valley Municipal Water District. He indicated that the three small lakes might be immune to quake damage, or even might discharge their water into Wilson Creek's drain without damage. Mr. and Mrs. Charles Demere, 815 High avenue; David Bowman, son of Mr. and Mrs. Douglas Bowman, 638 Orchard drive, and Nancy Olson, daughter of Mr. and Mrs. David Olson, 820 La Paloma. with a variety of early California-style specialty shops were announced last year and extensive remodeling and construction had begun when a group of investors announced it had bought out Mrs. Robinson's released in 1967. Air show The Inyodern Intercept Air Show will be held at Jan. 25 at the Inyokern • Airport. Events start at 8 a.m. Engineers yesterday introduced the nearly complete master plan of storm drains, designed to keep Redlands from flooding. The outline of multi-million-dollar future construction was unveiled by Omer Brodie, Redlands consulting engineer, as a plan to be finished by mid-summer. It represented a $31,800 investment by the County Flood Control District's Zone 3, whose advisory committee was first to see it. Every drain line in 56 square miles of the city and its surroundings — ranging from 30-inch pipelines to boxed conduits seven feet deep and 12 feet wide — were charted by Brodie and his seven associates. They surveyed 36,000 acres to gauge the slopes that floods will follow, and they came up with the area's first comprehensive comprehensive master plan. This is one of several major studies to be completed in Zone 3 of the County Flood Control system, said Chief Engineer W. A. Sidler. It covers Bryn Mawr, Loma Linda, Redlands and their environs, and is identified as Comprehensive Storm Drain Plan No. 4. "We studied 680 different storm records, going back through the available documents for 30 years," Brodie told Chairman Horace P. Hinckley and the advisory committee. Every slope and crevice in the district was taken into consideration so that the behavior of heavy rains might be contemplated. And Brodie's recommendations will indicate the construction that may be needed to accommodate accommodate all types of storms, ranging all the way from .44 inches per hour (classed as a two- year storm), up to a torrential and potentially disastrous 1.09 inches per hour (or a 100-year storm). Brodie recorded so many facts about the Redlands terrain and longtime rain records that he was able to trace contours on the map, showing where downpours may be expected. "We know approximately that if it's raining at the rate of .73 inches an hour — a 10-year storm volume — at one point, it will be raining at the same rate at certain other precise points," Brodie said. Having accumulated that kind of knowledge, the engineers could calculate the runoff from various slopes. They also could figure the exact direction of the flooding, leading to the measurement of culverts and flood channels that will be required to handle the water. Brodie's map — representing all the area from the Santa Ana river south to San Timoteo Canyon, Canyon, and from the City of Loma Linda east to the Crafton Hills — illustrated the major watercourses, such as Garden street and Crystal Springs Grade, and their many tributaries. Existing drainage systems were identified, and auxiliary installations were advised. "The older drains appear to be adequate in the upper areas around the city," said Brodie, complimenting the early-day engineers for their "remarkable foresight." He said the system generally was well designed, but, for modern requirements, the lower installations are not quite adequate. Sidler stated that the entire district will be blanketed by this and future engineering studies so that flood control works may be programmed more intelligently.' Within 30 days, he said, his office will contract contract for a similar study for the Yucaipa Valley, for which $20,000 was set aside in the new fiscal year's budget. "It's our aim to bring the hodge-podge of storm drains into a single comprehensive plan," said Sidler. "But that's the smaller part of the problem. "Later comes the whole question of funding the construction of an adequate flood control system, and in Yucaipa we don't have an answer yet. "Bonds or special assessments may be needed. But if present economic conditions persist, there could be a make -work program that would help get the costly job done." •69 MASTER FLOOD PLAN - Omer H. Brodie of Redlands, consulting engineer for the County Flood Control District, exhibits his map of the Redlands storm drain system on which the district will base future construction. Stars indicate observation points, related to rainfall records. Brodie points to the city's main channel for the collection of stormwaters, fed by laterals such as the ancient Mill Creek Zanja, the Garden street drain, the Morey Arroyo and others. Lighter contour lines show paths in which rainfall is expected to be uniformly heavy in heavy storms. (Facts photo by Kenison)
