Cate_gory 3.2: Mayor Highway Design <br /> Lower State Street Revitalization Project—City of Santa Barbara,CA <br /> Award Winning Project—Concrete Industry Award of Excellence for Outstanding Paving Project <br /> Mr. Flavell served as principal in charge, project manager and engineer of record. Lower State Street is a gateway to the <br /> City of Santa Barbara and was once HWY 1. This was a joint Public Works and Redevelopment Agency project. The <br /> existing streets were in poor condition and the soil in the area has an R-value of between 5 and 10. The value of 5 is the <br /> lowest value that can be calculated, meaning that these soils have very marginal support capacity. Because of the marginal <br /> soils,the decision was made to construct Portland Cement Concrete(PCC)streets that have the ability to bridge poor soils, <br /> with the benefits of longevity and low maintenance. One of the drawbacks is anytime utility repairs are made, the result is <br /> a substantial scar. Thought was given to protecting the longevity of the streets and all utilities(power,communications, and <br /> gas) and support infrastructure such as water and drainage were relocated to under the sidewalks. This project required <br /> coordination with businesses,meeting discretionary review board requirements and coordination with the utility companies. <br /> An extensive outreach program was implemented that continued through the construction of the project due to the number <br /> of stake holders involved. <br /> Project completed 1991 <br /> Santa Barbara Airport North of Hollister Infrastructure Improvements—City of Santa Barbara, CA <br /> Mr. Flavell was principal in charge, project manager of design, engineer of record and construction manager for this <br /> redevelopment of 25 acres that is zoned commercial and light industrial and still had the original infrastructure from the <br /> WWII Marine Air Base. A key component was master planning the lots and streets to take advantage of existing facilities <br /> and structures to remain and provide for future improvements. All utilities were replaced and upgraded including water, <br /> sewer, power, communications, gas and the streets and drainage facilities reconstructed. This project required a master <br /> planning effort to set the control grades and establish road vertical alignment that would provide drainage, most of the <br /> streets are designed at 0.20%slope, and conform to the existing driveways and building doorways, and comply with ADA. <br /> The master planning also allowed a more detailed fiscal analysis to be performed that resulted in the project being broken <br /> up into phases that could be constructed with available funding. The length of time from master plan to complete <br /> construction was eight years and included three construction contracts. We had to use elliptical pipe, and multiple pipe <br /> banks and specially design low head junction structures to move the water through the system. There was so little available <br /> head that all the junction structures had custom channel filleting to reduce the inlet and outlet headloss. There was so little <br /> cover that the pipes were put under the sidewalks to gain the 6"height of the curb to provide cover over the pipelines. This <br /> system has been tested with several significant rain events and received compliments from the City on how well the drainage <br /> system functions,compared to the condition before the improvements were made. The streets were dry despite heavy rain <br /> events. <br /> At the time Planning was recommending small curb returns and narrowing of streets as a design philosophy. Due to the <br /> intended use, we were able to persuade the discretionary approval bodies to allow 48'wide streets and 25' curb returns. <br /> This design allowed for the free flow of truck traffic and adequate street width to provide on street truck parking and Class <br /> 3 bike lanes. The project also included the si nalization of the Hollister i Lopez intersection a previously non-signalized <br /> P 1 9 p P Y 9 <br /> intersection. The project included development of two parks. <br /> Project Completed in 2003 <br /> Category 10.1: Roadway CEI <br /> Downtown Area Street Project—City of Santa Barbara, CA <br /> Mr. Flavell was principal in charge and construction manager for this 1.8 million dollar street widening and beautification <br /> project with signals, medians, decorative sidewalks, landscaping. Carrillo Street is a primary gateway to downtown Santa <br /> Barbara from US 101. Overhead utilities were undergrounded and upgrades to existing utilities were made. The project <br /> was phased to reduce impacts to this mixed used neighborhood of high end hotels, high end commercial retail including <br /> Sax Fifth Avenue,and transportation hub.CEI included weekly meetings,testing and review of test results,schedule review, <br /> MOT review, coordination with residents and businesses, quantities confirmation, pay request evaluation, laydown <br /> inspection, punchlist and corrections. <br /> Project Completed in 1992 <br /> Santa Barbara Airport North of Hollister Infrastructure Improvements—City of Santa Barbara,CA <br /> Mr. Flavell was principal in charge, project manager of design, engineer of record and construction manager for this <br /> redevelopment of 25 acres that is zoned commercial and light industrial and still had the original infrastructure from the <br /> 15 <br />
