execution of the work with all appropriate levels of review to ensure that the project's delivery <br />meets the standards and expectations of the City. <br />All of the City's reservoirs to be studied under this contract have lived long lives and have served <br />the City well for many decades. The City's reservoirs were once state of the art and very commonly <br />used throughout the Southern California region. Each of these design solutions lasted well into <br />the 1990's and early 2000's for small to medium sized tanks, surviving many earthquakes. For <br />example, the 20 MG Alvarado Regulating reservoir design of 1946 and the 35 MG Earl Thomas <br />reservoir design of 1955, both located at the City of San Diego's Alvarado Water Treatment Plant, <br />were "state of the art" for their era, but could not stand the test of time. Given their extreme <br />poor condition, there was no alternative to demolition and replacement. The demolition and <br />replacement of these two large reservoirs were designed by our Project Manager, Richard Brady, <br />P.E., BCEE. We have successfully met this challenge before in an award -winning way. We were <br />able to squeeze 42 MG of new storage in the existing 20 MG footprint by raising the HGL by 1 <br />1.
