CFA - Utilities Projects






		Lakeside Drive Sanitary Sewer Trunk Replacement A City of Reno investigation identified several issues associated with the existing Lakeside Drive trunk sewer including limited capacity and backwater deficiencies. CFA contracted with the City of Reno to provide topographic surveying, civil design, contractor bidding coordination, construction staking, and construction management services. Design tasks for this project included preparation of a sewer contribution and capacity analysis for the existing and future developed drainage areas. CFA’s engineering staff created a sewer distribution model using AutoCAD-based software and compared the results to actual flow data compiled by our field surveyors. The data compiled for the sewer capacity analysis was utilized for final design of the new sanitary sewer trunk line. Along with the preparation of final construction drawings and specifications, CFA coordinated the bidding process and oversaw all construction activities. Construction started in August 2010 and was completed in December 2010.

		2009 Sewer Rehabilitation - Phase 1A In anticipation of the 2010 RTC street reconstruction projects, the City of Reno contracted with CFA to design and manage construction of the 2009 Sewer Rehabilitation Project - Phase 1A. This project consisted of removal and replacement of 1,834 linear feet of small diameter sewer main in multiple locations throughout the city (e.g., Parr Circle, Brookside Way, Reactor Way, Taylor Street and Lake Street). CFA provided topographic surveying, utility research, final construction drawings, project specifications, bidding services, construction administration, construction inspection, and construction staking services. Utility coordination presented a challenge due to the random nature of the excavation sites. Black Eagle Consulting was our subconsultant providing geotechnical and materials testing services. We worked closely with NV Energy, AT&T, Charter Communication, American Fiber Systems, Level-3, MCI, Nevada Bell, and Kinder Morgan. Project construction began on July 13, 2009 and was completed on-time, under budget, and without conflict on August 27, 2009.

		2011 Montello-Carville Neighborhood Street & Sewer Rehabilitation The City of Reno owns and maintains over 700 miles of small and large diameter sewer collection mainline pipe. Some of this infrastructure was installed in the early 1950s. CFA worked with the City of Reno as project managers, design consultants, surveyors and inspectors to upgrade outdated sewer infrastructure. This sewer rehabilitation project identified approximately 20,000 linear feet of sewer mainline in need of replacement. CFA contracted with the City of Reno to analyze, research, and design new sewer mains. Many of the existing sewer lines were installed within easements in residential back yards. Our design eliminated many of these undesirable situations by re-aligning the sewer mains into the existing public street system. The elimination of backyard sewer lines, created lateral connection issues for approximately 120 homeowners. CFA designed and the City of Reno installed 120 new sewer lateral connections that included re-plumbing the existing houses. CFA worked closely with NV Energy, TMWA, Charter Communications, and AT&T to identify and re-align other infrastructure to finalize a practical design. This project was unique for the City of Reno due to the fact that the underground utility work and the street reconstruction work was bid under one contract. The City of Reno’s in-house engineers designed the roadway improvements. CFA combined the improvement drawings and specifications into a single-bid package. The project was awarded to Granite Construction in March 2011. The $7.5 million project was completed in November 2011. CFA provided civil engineering design, topographic and construction surveying, construction inspection, and construction management services.

		2008 Sewer Rehabilitation In January 2008, the City of Reno identified approximately 19,500 linear feet of small diameter sanitary sewer in need of replacement. CFA contracted with the city for preliminary design, final design, project management, construction documents, bid services, topographic surveying, construction staking, and construction management. Construction began in October 2008 within several high profile public roadways including Virginia Street, Kietzke Lane, Holcomb Avenue, Vassar Street, and Peckham Lane. This work was highly visible and sensitive to the surrounding property owners. Construction scheduling, notification, public relations, and responsiveness were the key project management components that helped in the success of this project. Design tasks included existing pipe assessment, utility research and coordination, and new pipe horizontal and vertical alignment and design. Construction then moved to the residential neighborhoods near Vine Street and West 1st Street and was completed in January 2009. Coordination continued with the residents, government agencies, RTC Ride, and utility companies to ensure a smooth and successful project.

		Keystone Avenue Sanitary Sewer Trunk Replacement The City of Reno Sanitary Division investigated and identified the Keystone trunk sewer as a deteriorated line in need of immediate replacement. CFA was contracted to provide surveying, final civil design, bid assistance, and construction management services for this project. CFA was responsible for all research, surveying, planning, and design for 6,000 linear feet of new sewer main. Since Keystone Avenue is a heavily-traveled roadway, many design challenges existed including traffic control, business access, and space constraints due to the many existing underground utilities. CFA surveyed and mapped all existing utilities and improvements, prepared a sewer capacity analysis based on existing and proposed development, and produced plan and profile construction drawings for the project. In addition to the gravity sewer design, CFA was responsible for the relocation design of approximately 2,000 linear feet of conflicting water main owned by Truckee Meadows Water Authority (TMWA). The City of Reno and TMWA entered into an interlocal agreement to construct the sewer and water mains under one contract. CFA administered the contractor bidding process and provided construction observation and administration services for the estimated $7.3 million construction project. Construction started in February 2007 and was completed on time and within budget in June 2007.

	City Center Apartments Montebello Apartments	Master Sanitary Sewer Studies CFA has performed numerous master sanitary sewer studies in conjunction with a wide range of development projects. In general, a master sanitary sewer study includes the following elements: analysis of the existing system, calculations of peak flows from the development, analysis of future flows potentially reaching the site from upstream, layout of the required infrastructure for the development, and recommendations for capacity improvements downstream, if needed. With the continual expansion of development boundaries, and the tendency for in-fill projects to increase density over what was originally planned, it is often necessary for the consultant to determine whether the existing sewer system has adequate capacity for the proposed project. In other cases, the sewer system is installed in anticipation of development and the consultant must design the sewer to economically meet present and future needs. A sampling of CFA projects with significant sanitary sewer components include the following: ArrowCreek (1,090 homes) Spanish Springs Business Park (411 acres) Summit Sierra Phase 1 (72 acres) Bear Creek Subdivision (28 homes) City Center Apartments (258 units) Montebello Apartments (864 units) Sterling Ranch Subdivision (198 homes) Heron’s Landing Subdivision (162 homes) FireCreek Crossing (70 acres) Curti Ranch (567 units) University of Nevada, Redfield Campus

	Sage Ridge School	Sanitary Sewer Lift Stations The need for a lift station is usually dictated by topography. When the sanitary sewer system reaches a depth that is too low to drain into the receiving sewer or when the required sewer route is too long, too deep, or too costly to construct, a lift station is designed to pump the effluent to a higher elevation. The effluent is pumped through a force main that is designed for pressurized flows similar to a water main. The force main may have a length of only 10 feet or as much as 10,000 feet or more. For sanitary sewer lift stations serving subdivisions, the local entities frequently require an economic analysis of life-cycle costs over a 50-year period to show that the cost to construct and maintain the lift station will be less than the cost of a deeper or longer gravity sewer system. CFA has prepared designs of sanitary sewer lift stations for the following projects: Spanish Springs Business Center/Pebble Creek Subdivision Sage Ridge School, Southwest Truckee Meadows Kings View Estates, Reno, Nevada East Meadows Subdivision, Kirkwood, California << Back to top >>

		Carson City Well Beautification Project CFA provided landscape architecture services for the beautification of wells, which are part of the municipal water system in Carson City, Nevada. These wells are in five locations throughout the city representing a wide variety of urban and environmental conditions. Each site varied in size from just a few hundred square feet to approximately one-half acre, with required improvements restricted to these limited areas. CFA was originally retained by the firm of Brown and Caldwell for conceptual aesthetic studies for landscape treatments at each location for use in public meetings. Carson City then retained CFA to develop construction plans for each location with coordinated details and specifications common to all sites. Plans also included limited technical details for street and pedestrian improvements. The design was done in 2005, and the work completed in 2007.

		Skylawn Water System In conjunction with the design and construction of the new Skylawn Funeral Home in San Mateo, California, CFA designed a completely new potable water system to provide domestic water to the new funeral home and several existing buildings throughout the cemetery, a separate non-potable fire water system to provide water for the sprinkler system for the new funeral home, and hydrants for additional protection of the funeral home and the existing cemetery administration building. The design includes an approximately one mile long transmission main from the well to a below-grade storage tank, a gravity distribution system to all buildings within the cemetery, and booster pump stations where required. The fire water system includes construction of a new discharge line from an existing reservoir and distribution lines to the funeral home and hydrants. Construction began in September 2004 and sitework was substantially complete in May 2006.

		Galena Water System CFA staff completed the Phase 2 final design for this water system, which includes approximately 1.5 miles of transmission piping, well house site development, jack-and-bore under the Mt. Rose Highway, and U.S. Army Corps of Engineers permitting for a crossing of Whites Creek. The water from this system serves the domestic supply, fire storage, and supplemental irrigation needs of properties in the Mt. Rose Highway area. CFA obtained the entitlements for the well houses, provided the landscaping plans, and created photo simulations of the proposed structures for use during the public hearing process. The westerly well house was screened with berming to reduce the visual impact to adjacent residences. This system was constructed with private funds and was dedicated to Washoe County. Phase 3 consisted of the design and construction of an additional 6,000 linear feet of 8-inch distribution waterline. This phase connects two separate water systems (Washoe County and the South Truckee Meadows General Improvement District). CFA obtained all entitlements and coordinated the construction, which occurred in 2001-02. The engineer’s estimate for Phase 2 was $1,600,000. The award amount was $1,438,915 and the construction cost was $1,468,713. For Phase 3, the engineer’s estimate was $425,000, the award amount was $389,163, and the construction cost was the same as the award amount.

		ArrowCreek Water Tank #2, Well House #3 Booster Station, and Transmission Line CFA provided design and construction services for this key component of the ArrowCreek water system. The work consisted of obtaining a special use permit for a two million gallon water tank and booster pump house structure; final design of the civil infrastructure for the tank, including access road design; landscape architecture; surveying; and the final civil design for approximately 9,000 linear feet of transmission waterline. The engineer’s estimate was $1,700,000.

		Northwest Tank and Transmission Line Award-Winning Project CFA was responsible for all phases of planning and design for this water system in the Spanish Springs Valley. The project included 6,000 linear feet of 14-inch diameter transmission line crossing both private land and Bureau of Land Management (BLM) property and two water storage tanks. The tanks, one at 1.5 million gallons and one at 1.0 million gallons, are located on BLM property in areas that contain slopes exceeding 20 percent. The civil infrastructure design included an access road that was designed to withstand the 100-year flood and several pressure reducing stations on the water main servicing new developments. Construction costs for this project exceeded $1 million. In 1999, this project was given an Award of Distinction for Excellence in Environmental Design by the Washoe County Design Review Committee. In addition to the water system, CFA was responsible for the preparation of a water master plan report for approximately 2,990 homes, 500 acres of industrial park, and 50 acres of commercial property in the Specific Plan area. Existing systems were analyzed and a plan was developed to serve the future needs of the area. Cost estimates were prepared to establish the feasibility of several development alternatives.
