| 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. |

Master Sanitary Sewer Studies 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:
