_.aPPpppp� 1 ('st 1 Ok 'S, II Proposal For On -Call Water Resources Engineering Services capacity. The result of this is that water velocity during pumping is much higher in the sections of screen that produce the most water. During pumping, small sand particles mobilize and migrate through the well filter pack and wedge into the pore space, reducing permeability in the filter pack. Mitigation of this issue would include careful well development to remove the sand and resettle the filter pack and modification of pumping operations to reduce sharp changes in water velocity that mobilize fine-grained aquifer sand. Prior to redevelopment, it is recommended to review the factors that can cause this reduction in specific capacity. The review would include assessment of biological and cementation plugging and review the original, well construction documents including the sieve analysis performed to size the filter pack and the daily construction (if available). As part of developing a mitigation approach, spinner logs may be recommended to verify production zones. Storm Drain Design and Drainage Analysis. The firm's drainage engineering services include the design of canals, culvert crossings, water control structures, roads, levees, bridges, and pump station structures as well as stormwater treatment services, such as bioretention, filters, rainwater capture and reuse, and large flood control projects. Representative project areas range in size from one to more than 130,000 acres, and our engineers have been called upon by numerous public agencies and major agricultural, industrial, and residential developers. Our staff has the experience to conduct preliminary studies and drainage consultation, prepare stormwater management plans, conduct bridge scour analyses, prepare FEMA map revisions, perform floodplain analyses, and coordinate permit applications on behalf of our clients. Kimley-Horn's engineering professionals are well -versed in stormwater regulations throughout the state of California to help clients understand the permitting process and guide them through difficult development decisions. Sewer Design and Wastewater Services. Kimley-Horn is committed to providing clients with cost- effective and state-of-the-art design solutions. We bring a unique understanding of water/wastewater and recycled water system operations, end -user requirements, and design capabilities that enable Kimley-Horn to produce plans that are constructible, meet the needs of our clients, and minimize construction costs. We bring a complete understanding of water, wastewater, recycled, and reclaimed water systems from the initial needs analysis and master planning to detailed design and construction phase services. Kimley-Horn has extensive experience in design and construction of a wide variety of projects, including planning and design of transmission and distribution pipelines; trenchless technology designs; right-of-way and easement coordination; utility coordination; pipeline rehabilitation; water treatment facilities design; tanks and booster pump station design; and permitting. Many of Kimley-Horn's professionals are locally and nationally recognized in their respective fields. Utility Design Coordination. Every project is unique and presents its own special design challenges; however, the most frequent challenge we face in local municipal projects is related to existing utilities. Most of the projects under this category are in developed areas where utility facilities are currently within the proposed project area and any improvement will generally affect or be affected by the location of the utility facilities. Kimley-Horn believes in drawing the utility lines and features to their true size in our plans to aid in identifying conflicts early in the design phase; potholing potential conflict locations when budgets allow, which gives a better understanding of the locations of the existing utilities; and extensive coordination with the various utility companies. We also use three-dimensional (3D) modeling of utilities to identify potential conflicts in the early stages of design. This method has helped us to avoid discrepancies between construction documents and actual field conditions that have resulted in cost-effective and timely execution of projects. Our utility design team has successfully completed sewer and water infrastructure projects for various agencies in Southern California. These projects consist of sewer and water main replacement, City of Santa Ana ' IWOC77003.22 Kimley>Morn 8
