This Mitigated Determination of Non Significance is based on the project as proposed and the impacts and potential mitigation measures reflected in the following environmental documents: Environmental Checklist (dated October 21, 2003, prepared by Skillings/Connolly). Finding of No Significant Impact and environmental documents for the construction and operation of a Class A wastewater treatment plant, constructed wetlands, and a reclaimed water distribution system (dated January 25, 1996). Determination of Non-Significance and environmental documents for the construction of a Class A Wastewater Treatment Plan (1 million GPD), constructed wetlands, and a reclaimed water distribution system for reusing 100% of Yelm’s wastewater (August 8, 1997). Environmental Impact Statement for the City of Yelm Comprehensive Plan and Joint Plan with Thurston County (January 3, 1995). Addendum to Existing Environmental Document for the 2002 Amendments to the Yelm Comprehensive Plan, including the Comprehensive Water Plan update (May 9, 2002). These environmental documents are hereby adopted by reference pursuant to Section 197-11-630 WAC. 2. The potable water tank will be an aerial structure approximately 160 feet in height and 53 feet in width located at the southeast corner of the Yelm Public Works facility at 901 Rhoton Road. The property is zoned industrial with vacant industrial land to the east, a concrete plant to the south, a timber equipment storage and repair facility to the north, and residential and institutional uses to the west. The reclaimed water tank will be approximately 30 feet in height and 53 feet in width located at the site of the sewer treatment plant. The property is zoned industrial and is surrounded by vacant industrial land and a fiberglass manufacturing plant. 3. Both sites are characterized by Spanaway gravelly sandy loam, a soil type that is not especially susceptible to erosion. The Yelm Development Guidelines require an erosion control plan as part of the civil engineering plan review to ensure that temporary erosion control measures sufficient to preclude a significant environmental impact are in place during construction. 4. There are no known endangered, threatened, or candidate species of animals or plants located at either site. Both the public works facility and the sewer treatment plant are existing industrial type activities. 5. There are no habitable structures or facilities with a non-transient population within the splash zone of the proposed water tanks. Both tanks will be constructed to current seismic and structural requirements. 6. The reclaimed water tank will be no taller than a typical industrial use locating in the industrial zone and will not be within the view shed of any existing residences. The reclaimed water tank will be located within an existing complex of buildings, some of which are of similar height to the proposed tank. The potable water tank will be approximately 160 feet tall and will be visible at many locations in the City. The tank will be in the view shed of existing residential uses to the west of the site. The location of the tank on the site minimizes view impacts by its location near existing tree’s on the property, which have been proposed to remain, and it’s location near the southeastern corner of the property. The tank is proposed to be constructed of neutral colors designed to minimize it’s aesthetic impact.  Conclusions of Law and Mitigation Measures 1. A temporary erosion control plan which meets the requirements of the Yelm Development Guidelines shall be included with the civil plan review. 2. The potable water tank shall be painted in colors and patterns designed to mitigate aesthetic impacts by minimizing the differences between the background as viewed from residential properties to the west of the tank and the tank itself. 3. Additional uses of either proposed water tank, including the attachment of antennae or telecommunications facilities, will require site plan review approval by the City of Yelm.
