CASE # UPDATE ON IMPROVI/MENT PROJECT #08-Z7,167TH AVENUE NW REALIGNMENT AND ACCEPTANCE OF APPRAISALS AND AUTHORIZATION TO NEGOTIATE LAND ACQUISITIONS By: Tim Himmer, Assistant City Engineer Background• On April 8, 2008 City Council authorized staff to prepare plans and specifications for the realignment of 167th Avenue NW. As you may recall this realignment related to segment one only (Nowthen Boulevard to Limonite Street). During that meeting staff expressed interest in expanding the project approximately 500 feet to the west to eliminate the next set of drastic curves along 166th Avenue NW, and subsequently received approval to do so. On June 24, 2008 this project was again discussed at the City Council as it related to the ultimate alignment of the west 500 feet. Three alternatives were reviewed and staff was directed to look into the potential costs associated with each. The main faces of the options presented had to do .with potential impacts to property owners and an existing wetland within the project area, and are as follows: 1. A northerly swing of the right-of--way through the existing home located at-7131 166th Avenue NW. This would require a total acquisition of approximately 7.6 acres and include building demolition. The lot (which is mostly wetland) would be very difficult to reuse after theright-of--way and wetlands are preserved as there would be little buildable area remaining. See Figure 1. 2. A slight southerly swing of the right-of--way through the northern portion of 7100 166tH Avenue NW and the southeast corner of 7131 166th Avenue NW (including minor impacts to an existing wetland). The acquisition necessary to complete this option would include approxunately 6,650 square feet from 7100 166th Avenue NW, including. 5,500 square feet of wetland impacts, acid 3,650 square feet from 7131 166th Avenue NW. See Figure 2. 3. Amore pronounced southerly swing oftheright-of--way through the northern portion of 7100 166th Avenue NW (including significant wetland impacts) and the northwest. corner of 7046 166t" Avenue NW. This option.was contemplated based. upon the desire of the property owner at 7131 166th Avenue NW to not be impacted at all by this project., Doing so forces the acquisition onto the property at 7046 166th Avenue NW amounting to approximately 2,915 square feet. The impacts to 7100 166th Avenue NW increase to a right-af--way acquisition of 20,723 square feet, including 11,667 square feet of wetland impacts, and also approximately 12,900 square feet of additional acquisition due to the fact that the new right-of--way would separate a portion of the property from the whole. See Figure 3. The estimated casts associated with. each of these options are as follows (these costs are on.Xy for• the westerly S00' of the project): 1. The appraised value of the land is $164,000 and the estimated market value of the house is $257,000, resulting in a total valuation of $421,000. Demolition of the house would cost approximately $7,500,-and additional environmental im~estigation may be warranted on portions of the property used for off-road driving in lowland areas. This option would not impact any wetlands, and would severely limit the use of any remnant property. The total estimated crcquisitiotz costs under this option are $431,466. -333-
