Why this matter is before the board: The Water Department has identified the need to survey existing utilities along the planned pipeline replacement projects for 2008. This cost is expected to be above $15,000. Board authorization is required for expenditures in excess of$15,000. 2. History: The District is currently undertaking a multi-year program of replacing leaking pipelines throughout the water service area. As discussed in previous staff reports, the following streets have been identified for construction in 2008. • Regency Circle - Glenshire • Lancaster Place - Glenshire • Somerset Drive - Glenshire • Windsor Way - Glenshire • St. James Place - Glenshire • Shore Pine Road - Sierra Meadows • Frond Road - Sierra Meadows • Laurel Court - Sierra Meadows • Redbud Court- Sierra Meadows • Whitetail Lane - Prosser Lakeview • Copenhagen Drive -Tahoe Donner • Hillside Drive -Tahoe Donner 3. New Information: Most of the streets noted above are outside of the Tahoe Donner subdivision. The District has undertaken a number of pipeline replacement projects within the Tahoe Donner subdivision and the Water Department has a level of confidence in the as-built drawings for that area. The Water Department has been able to avoid the expense of surveying in the Tahoe Donner because of the reasonably accurate as-built drawings. However, relative few projects have been undertaken in other parts of Truckee. In fact, there have not been any replacement projects in Prosser Lakeview of Glenshire. Consequently, it is prudent to have these areas surveyed for the first few replacement projects in order to establish whether the as- built drawings are accurate or not. The Water Department has prepared a Request for Proposals for Surveying. A copy of that document is attached. These utility surveys are described in the RFP as Task 1. The District is pursuing construction of a new corporation yard on the property north of Interstate 80 and east of Bridge Street. The corporation yard project will be permitted through the Town of Truckee Building Department. One requirement for the improvement plans is that all trees larger than 6-inches in diameter must be shown on the drawings. The LIDAR and aerial photography work recently completed by the District does not have a level of accuracy sufficient to identify individual trees. Therefore, an on-site survey is required. This tree survey is included in the RFP as Task 2. In addition, two utility pipelines (potable water and sanitary sewer) have been constructed on the corporation yard property since the last utility survey work was performed in 2003. Considering that a surveyor will be on-site to perform the tree survey, it is prudent to locate the existing utilities as well. This is also included as Task 2. 4. Recommendations: 1) Authorize the Water Department to issue the Request for Proposals for Surveying. 2) Authorize the Water Department to review the proposals and develop a recommendation for consideration by the Board.

The District is hereby requesting proposals - both cost and schedule - for surveying as described in the attached Anticipated Scope of Work. The work encompassed by Task 1 shall be delivered to the District no later than September 1, 2007. The work covered by Task 2 shall be delivered to District the no later than December 1, 2007.
