Box 97034 Bellevue, WA 98009-9734 PSE.com March 5, 2019 Jill Ding Renton City Hall, 6th Floor 11055 South Grady Way Renton, WA 98057 RE: Renton Segment Energize Eastside – Vegetation Replacement Approach Conditional Use (File# 17-120556-LB) Dear Ms. Ding: Puget Sound Energy, Inc. (PSE) provides the following information to the City of Renton (City) to support the above referenced CUP permit application for the Energize Eastside project (Project), which also traverses Redmond, Bellevue, Newcastle, and unincorporated King County. Within the City, the project entails the replacement of two existing 115 kV transmission lines with two new 230 kV lines, all within an existing utility corridor that was established in the late 1920s and early 1930s. Changing the 115 kV system over to a 230 kV system will require vegetation management (i.e., tree trimming and removal) in order to ensure compliance with federal requirements. As part of the permit application process, PSE prepared tree retention worksheets 1 for the Project. PSE is committed to fully restoring impacted areas and replacing trees for the Energize Eastside project. In an effort to provide equitable tree replacement amongst the cities that are reviewing Energize Eastside permit applications and to meet PSE’s restoration objectives, the following vegetation management approach and corridor restoration plan are proposed. Federal Requirements The Federal Energy Regulatory Commission (FERC) has certified the North American Electrical Reliability Corporation (NERC) as the electric reliability organization who establishes legally enforceable mandatory standards for the U.S. bulk power system. PSE is required by NERC standards to maintain safe clearances between vegetation and utility lines. Specifically, NERC FAC‐003‐42 (Transmission Vegetation Management) sets forth the vegetation management requirements for transmission lines that operate above 200 kV. Under NERC FAC‐003‐4, PSE must prevent encroachments of vegetation into the Minimum Vegetation Clearance Distance (MVCD) of its applicable line(s). Since the Project entails replacing the existing 115 1 See Tree Retention Worksheets previously submitted. 2 https://www.nerc.com/_layouts/15/PrintStandard.aspx?standardnumber=FAC‐003‐ 4&title=Transmission%20Vegetation%20Management&jurisdiction=United%20States Ms. Jill Ding March 5, 2019 Page 2 kV lines with 230 kV lines, the upgraded transmission lines must comply with the NERC standards and PSE’s 230 kV vegetation management standards, which generally require the removal of trees with an expected mature height of more than 15 feet within the Wire Zone. Management of trees within the transmission right of way (ROW) may also be required depending on tree species, tree health, distance from the wires, and topography. Using GIS modeling that incorporates the above referenced standards, it has been estimated that there are approximately 240 significant trees that do not meet the NERC and PSE vegetation management standards in Renton, the majority of which are located on private property. These trees may need to be removed to meet the vegetation clearance requirements; however, it is important to note that these trees are already located within an existing and managed transmission line corridor and likely have been pruned or topped to accommodate the existing transmission lines. The final number of trees to be removed may change as the original tree inventory field work was completed on October 13, 2016, and may also include trees that have since been removed by private property owners. Additionally, the GIS modeling estimate does not account for changes in the overall significant tree inventory attributed to tree growth. These factors are not expected to significantly affect the total number of trees removed in the City. Working with Private Property Owners to Replace Trees Removal of trees associated with transmission lines, especially when upgrading within an existing transmission line corridor, is a dynamic process. One factor that can influence evaluating which trees need to be removed is limitations on access to private property during the design phase of a project. Not all property owners along the corridor meet with PSE prior to construction; therefore, property‐ specific tree removal assessment cannot always be completed. Using the data collected during the initial tree inventory work, the Vegetation Impact Analysis (VIA) identified an estimated number of trees that are anticipated for removal in the corridor for each property. Since collection of the data and subsequent analysis, PSE has been inviting property owners to meet and discuss vegetation replacement options. At the property owner meetings, project team staff shares the current project design and gathers the property owners’ input on how their respective properties can be replanted. Project staff shares an Energize Eastside‐specific plant palette (see attached), a reference guide of compatible replacement vegetation, and asks property owners to share their plant preferences. Also during meetings with property owners, PSE evaluates and re‐confirms, and if necessary, updates the original tree inventory data. Using these tools, combined with discussions with the property owners, the information gathered informs the development of a Draft Landscape and Tree Replacement Plan (see sample). Following the initial property owner meeting, project staff develops the property‐specific Draft Landscape and Tree Replacement Plan. A second meeting is then scheduled with the property owner to share and discuss the draft plan for their property. During the second meeting, the plan is reviewed carefully with the property owner and changes, if necessary, are discussed and documented. Ms. Jill Ding March 5, 2019 Page 3 PSE’s approach is to encourage property owners to incorporate additional trees into their landscape and tree replacement plans; however, PSE cannot require property owners to do so nor can it dictate the types of trees and/or vegetation that is planted. While some property owners take this as an opportunity to add additional trees to their properties, others decline the offer of any replacement trees. As of the end of December 2018, PSE has met with slightly more than half of the Renton property owners who are expected to have vegetation changes along the route. City Rights of Way Tree Valuation As stated earlier, PSE proposes to use the same ROW tree valuation approach in Renton that has been proposed in Bellevue to maintain an equitable approach among all affected cities. PSE recommends using the method outlined in the Council of Tree and Landscape Appraisers’ Guide for Plant Appraisal, 10th ed. (2018) to assess the value of trees that require removal from the City ROW. Based on PSE’s review, there are five trees located in City ROW that would fall into this category. PSE will provide in‐ lieu fee mitigation to the City for removal of City ROW trees. This method of in‐lieu fee compensation is limited to City ROW trees and cannot be applied to trees on other city‐owned properties or private properties over which PSE has easements PSE’s easements, which were established in the late 1920s and early 1930s, grant PSE the right to maintain transmission line compatible vegetation. Consequently, trees on City (non‐ROW) and privately owned property are only eligible for replacement with transmission line compatible species, not compensation. Tree Replacement Approach Under Renton Municipal Code (4‐4‐130.C.12 3), tree removal within PSE’s existing easement is an allowed activity. Therefore, a Routine Vegetation Management Permit is not required. The Tree Retention Worksheets provided as part of the Energize Eastside application materials also confirmed that replacement trees are not required under Renton’s code. However, PSE remains committed to working with property owners to replace significant trees removed and to restore other vegetation impacts to the extent possible 4. Specifically, PSE proposes as follows: 3 Utilities, Traffic Control, Walkways, Bikeways within Existing, Improved Rights‐of‐Way or Easements: Within existing improved public road rights‐of‐way or easements, installation, construction, replacement, operation, overbuilding, or alteration of all natural gas, cable, communication, telephone and electric facilities, lines, pipes, mains, equipment or appurtenances, traffic control devices, illumination, walkways and bikeways. If activities exceed the existing improved area or the public right‐of‐way, this exemption does not apply. Restoration of disturbed areas shall be completed. 4 In addition to PSE’s plans to work with private property owners and determining the value of City ROW trees, PSE has also implemented a proactive effort to help increase tree numbers in Renton. PSE partnered with the Arbor Day Foundation’s Energy‐Saving Trees Program to provide trees to those residents that want to add trees to their property in a manner that can help offset energy usage. While in most cases these trees are not along the project corridor, they are within the City limits and help buffer potential tree loss due to factors such as mortality and property owner changes (i.e., a new property owner removes existing trees due to landscaping preferences). PSE initiated use of the Energy‐Saving Trees Program in 2018 to help offset anticipated tree removal. During the 2018 spring and fall events, PSE and the Arbor Day Foundation provided 269 trees to City residents. PSE believes that use of this program allows for trees to be provided to property owners who want additional trees. Ms. Jill Ding March 5, 2019 Page 4 • If vegetation is removed for construction, where possible and as directed by the property owner, replace with appropriate native plant species; and • Replant disturbed areas using native vegetation, where possible, that would meet transmission line clearance requirements and would not need to be removed or require maintenance (i.e., trimming) in the future. To implement these measures, PSE will implement the following tree replacement program and facilitate corridor restoration as described below. PSE has successfully used the following proposed tree replacement approach on similar 115 kV to 230 kV upgrade projects. Vegetation management and replacement in long‐term utility corridors that are primarily established by easement can be challenging. Although PSE has rights to operate transmission lines in the corridor, the ability to require property owners to accept mitigation (i.e., additional trees) is not specifically identified in the easements. Additionally, in PSE’s experience, vegetation replacement on properties where the owners actually want additional plantings is the most successful. This approach allows for finalization of tree replacement numbers once construction begins. The proposed steps for tree replacement include: • At the time of construction, documentation of trees that are removed on a property‐by‐ property basis will be collected. This will include the tree species, inventory tag numbers, and diameters at breast height (dbh) at the time of removal. • This information will be cross‐referenced to the proposed landscape and tree replacement plan that was provided to the property owner. Changes to the proposed plan could occur based on a number of factors such as, but not limited to, property ownership changes and prior removal of trees by the owner. • Upon completion of replanting, PSE will document the number and species of trees that have been removed and planted. • PSE will monitor plant survival for one year after the planting, with replacement of the plant if a plant does not survive. Corridor Restoration In addition to tree and vegetation replacement on private properties, PSE has identified areas along the Project corridor that will benefit from targeted post‐construction restoration efforts. By using the existing transmission line corridor and focusing restoration efforts on the properties that are owned by PSE, corridor restoration and improvements have the highest potential for success. While most of the transmission line corridor within the City is established by easements, the properties located directly north of PSE’s Talbot Hill and BPA Maple Valley substations are owned by PSE. These parcels are well‐ suited for restoration and improvements following construction as PSE has control of the properties and can ensure maintenance of the vegetation. As part of the restoration effort, PSE will use native species with an emphasis on vegetation that promotes use by pollinator species. In addition, removal of invasive plant species will be included in the restoration work. The restoration efforts that focus on pollinator habitat will be implemented on parcel 2023059002, which is owned by PSE. Using PSE’s property helps ensure the successful implementation and maintenance of the corridor restoration. Ms. Jill Ding March 5, 2019 Page 5 Additional details are provided in the attached Restoration Plan – Pollinator Habitat (see attached). PSE believes that this approach is well‐suited for the areas as it will help respond to declining pollinator populations at the local level, provide a passive recreational amenity, and has long‐term vegetation compatibility with transmission lines.
