PUGET SOUND ENERGY Mr. Tim Peterson Director of Public Works 901 Rhoton Road P.O. Box 479 Yelm, WA 98597 RE: Longmire Street SE Improvements Puget Sound Energy -Gas and Electric Facilities Dear Mr. Peterson: June 27, 2005 JAN 2 ~ 1005 The purpose of this letter is to formally inform the City of Yelm (City) of gas and electric facility infrastructure work that will need to be completed this summer due to planned improvements to Longmire Street SE. Since May of this year, Puget Sound Energy (PSE) has had a number of meetings and preliminary discussions with representatives of Tahoma Terra, Terra Valley and Thurston Highlands regarding various gas and electric service issues associated with these developments. Planned construction activities for these developments will impact PSE in the near term including the improvements to Longmire Street SE from Yelm Highway to the western end of Longmire Street SE near Thompson Creek. PSE has an existing overhead three-phase electric distribution line along the north side of Longmire Street SE. Based on preliminary discussions with representatives of the proposed developments, we anticipate that the improvements to Longmire will require the relocation of three or four distribution poles. Steve Mix of SCA Consulting Group indicated that PSE and the City of Yelm would be provided with completed civil sheets for Longmire Street SE on June 27a'. Once we have the road improvement plans we can initiate our relocation design work, which we anticipate will take approximately four weeks to complete. While our design work is underway, PSE will assess whether any easements will be required for the relocated poles and if so, will initiate easement acquisition. The PSE Real Estate Department will not release the pole relocation project for construction until all of the required operating rights have been obtained. The overhead facilities along Longmire Street SE are currently located in private easement. Therefore, the cost of the relocation work would be borne by whomever is requesting the relocation, which in this case is the developer of Tahoma Terra, Terra Valley and Thuston Highlands. Prior to incurring design or relocation costs we will need to sign an agreement with the developer to cover all of the costs associated with relocating the poles. The pole relocation work will take approximatey one week of crew time to complete. Once the dates for the pole relocation work are known, PSE can allocate the crew time and put it on the schedule. The earliest realistic date that the crews could start the relocation work is approximately August 8, 2005. Of course the PSE start date is Puget Sound Energy, Inc ~ 3130 South 38th Street Tacoma, WA 98409 contingent upon timely receipt of the Longmire civil design, acquisition of easements, execution of agreements, issuance of permits and completion of preliminary road work by the developer. PSE will also need to install a new 8" IP gas main along Longmire Street SE from SW Berry Valley Road past Durant Street SE to the proposed entrance of Tahoma Terra. The new gas main will help provide gas service to the proposed development. In order to design this new gas main, we will need the final plans for the proposed improvements to Longmire Street SE. PSE will also install two 4-inch and three 6-inch empty electric conduits in the same trench with the gas main. In the future, electric cables can be pulled through these conduits to provide additional electric capacity as the electric load in the area grows. In summary, we are working with the developers of Tahoma Terra, Terra Valley and Thurston Highlands to ensure we meet their needs in a timely manner. To do this, we need to design our new and relocated facilities based on the final design for proposed improvements to Longmire Street SE. We also need to ensure that our pole relocation and gas main design is acceptable to the City of Yelm. We understand that the reconstruction of Longmire Street SE is anticipated to start in 6 to 8 weeks. This does not give PSE much time to complete our gas and electric design work and schedule our construction work. In July and August our construction season is at a peak and there is a long lead-time to schedule crews for new projects. Sandy Leek of PSE has arranged a meeting for July 13, 2005 to discuss general development issues in Yelm. The meeting will include representatives of PSE, Potelco, SCA, City of Yelm and Thurston EDC staff. We can use this meeting as an opportunity to continue to communicate and coordinate on the Longmire Street SE road improvement and gas/electric construction work. Do not hesitate to call me at (253) 476-6037 if you have any questions or need additional information. I look forward to working with you on this project.
