Cateaory 3.2: Major Highway Design Lower State Street Revitalization Project — City of Santa Barbara, CA Award Winning Project— Concrete Industry Award of Excellence for Outstanding Paving Project Mr. Flavell served as principal in charge, project manager and engineer of record. Lower State Street is a gateway to the City of Santa Barbara and was once HWY 1. This was a joint Public Works and Redevelopment Agency project. The 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 lowest value that can be calculated, meaning that these soils have very marginal support capacity. Because of the marginal soils, the decision was made to construct Portland Cement Concrete (PCC) streets that have the ability to bridge poor soils, with the benefits of longevity and low maintenance. One of the drawbacks is anytime utility repairs are made, the result is a substantial scar. Thought was given to protecting the longevity of the streets and all utilities (power, communications, and gas) and support infrastructure such as water and drainage were relocated to under the sidewalks. This project required coordination with businesses, meeting discretionary review board requirements and coordination with the utility companies. An extensive outreach program was implemented that continued through the construction of the project due to the number of stake holders involved. Project completed 1991 Santa Barbara Airport North of Hollister Infrastructure Improvements — City of Santa Barbara, CA Mr. Flavell was principal in charge, project manager of design, engineer of record and construction manager for this redevelopment of 25 acres that is zoned commercial and light industrial and still had the original infrastructure from the WWII Marine Air Base. A key component was master planning the lots and streets to take advantage of existing facilities and structures to remain and provide for future improvements. All utilities were replaced and upgraded including water, sewer, power, communications, gas and the streets and drainage facilities reconstructed. This project required a master planning effort to set the control grades and establish road vertical alignment that would provide drainage, most of the streets are designed at 0.20% slope, and conform to the existing driveways and building doorways, and comply with ADA. The master planning also allowed a more detailed fiscal analysis to be performed that resulted in the project being broken up into phases that could be constructed with available funding. The length of time from master plan to complete construction was eight years and included three construction contracts. We had to use elliptical pipe, and multiple pipe banks and specially design low head junction structures to move the water through the system. There was so little available head that all the junction structures had custom channel filleting to reduce the inlet and outlet headloss. There was so little cover that the pipes were put under the sidewalks to gain the 6° height of the curb to provide cover over the pipelines. This system has been tested with several significant rain events and received compliments from the City on how well the drainage system functions, compared to the condition before the improvements were made. The streets were dry despite heavy rain events. At the time Planning was recommending small curb returns and narrowing of streets as a design philosophy. Due to the intended use, we were able to persuade the discretionary approval bodies to allow 48' wide streets and 25' curb returns. This design allowed for the free flow of truck traffic and adequate street width to provide on street truck parking and Class 3 bike lanes. The project also included the signalization of the Hollister / Lopez intersection, a previously non -signalized intersection. The project included development of two parks. Project Completed in 2003 Cate_aory 10.1: Roadway CEI Downtown Area Street Project — City of Santa Barbara, CA Mr. Flavell was principal in charge and construction manager for this 1.8 million dollar street widening and beautification project with signals, medians, decorative sidewalks, landscaping. Carrillo Street is a primary gateway to downtown Santa Barbara from US 101. Overhead utilities were undergrounded and upgrades to existing utilities were made. The project was phased to reduce impacts to this mixed used neighborhood of high end hotels, high end commercial retail including Sax Fifth Avenue, and transportation hub. CEI included weekly meetings, testing and review of test results, schedule review, MOT review, coordination with residents and businesses, quantities confirmation, pay request evaluation, laydown inspection, punchlist and corrections. Project Completed in 1992 Santa Barbara Airport North of Hollister Infrastructure Improvements — City of Santa Barbara, CA Mr. Flavell was principal in charge, project manager of design, engineer of record and construction manager for this redevelopment of 25 acres that is zoned commercial and light industrial and still had the original infrastructure from the 15 P65
