Kimley-Horn <br />can meet all your civil engineering and roadway design <br />needs. Since 1967, Kimley-Horn engineers have designed <br />more than 4,000 miles of roadway, including highways, <br />highway interchanges, urban arterials, and neighborhood <br />streets. These projects —performed for state departments <br />of transportation, cities, and counties —have included <br />route/corridor studies, schematic design, maintenance <br />of traffic plans, construction sequencing, and final plans, <br />specifications, and estimates (PS&E). Our in-house staff <br />is equipped to address all aspects of roadway design <br />projects, including pavement rehabilitation, roadway <br />realignment and widening, intersection geometrics, utility <br />relocations, and erosion control. Also, Kimley-Horn's team <br />has provided municipal agencies with design services for their public facilities such as parks, parking <br />lots, parking structures, libraries, senior and community centers. We have gained extensive experience <br />in dealing with local regulatory and other agencies to secure the permits and approvals necessary for <br />the building and upgrading of municipal facilities. <br />Water Improvement Design and Coordination. Our water resources engineering team has <br />successfully completed water infrastructure projects for various agencies in Southern California. These <br />projects consist of water main replacement, realignment, upsizing and capacity increase, master <br />planning, existing system evaluation and maintenance and operational support. <br />Drinking Water. Kimley-Horn has provided advanced water treatment systems to ensure a safe <br />drinking water supply. Services include reverse osmosis, membrane softening systems, wellfield <br />development, permitting of membrane concentrate waste disposal, master pumping stations, <br />metering stations, and water storage facilities. <br />Reclaimed Water. Effluent disposal and reuse is perhaps the most challenging area facing <br />municipalities today. Kimley-Horn has assisted local water agencies navigate the planning, design, <br />and construction of an entire reclamation system. With increasingly stringent regulations on effluent <br />quality and the increased pressure on our water supply, effluent disposal and reuse is an issue that <br />has become central to our efforts in serving wastewater utilities. Our team is well acquainted with <br />the issues regarding effluent disposal and reuse and the necessary reclaimed water systems to <br />provide these functions. <br />Well Rehabilitation Design. A combination of three factors can cause water production decline. <br />The first is a regional decline in water elevations that shift the "static" water level downward. The <br />second is a decline in water levels in the local aquifer caused by continuous pumping. The third is <br />a decline in specific capacity caused by a plugged filter pack or well screen. The regional decline <br />in water levels is not controllable and groundwater levels will recover through natural recharge. <br />The reduction in specific capacity requires corrective action in the form of root cause evaluation, <br />well redevelopment, and possibly modification to pump location and flow rate. The decline in <br />specific capacity could be a result of a reduction of permeability near the well screen. This type of <br />permeability reduction is often the result of biological fouling, cementation, or the intrusion of fine- <br />grained aquifer sand into the gravel pack surrounding the well casing.
