Box 9960 College Station, Texas 77842 Re : Westfield Village , Phases 2 & 3 -Revised Oversize Participation Request Dear Spencer : Accompanying this letter is a revised estimate of oversize participation costs associated with the development of Westfield Village , Phases 2 & 3. Oversize participation is estimated for two aspects of the development. The first is the construction of Victoria Avenue , increasing its width from 39 feet to 48 feet as called for on the city 's Thoroughfare Plan. The estimated cost for this oversizing is $20 ,201.80. The second oversize participation request is for the increased water line size on Victoria Avenue. The line is being increased from an 8" to a 12 " diameter to match the existing line on other portions of that street. The smaller line size was determined to be sufficient in the Water Report submitted with Phase 1. The estimated cost for this oversizing is $16 ,608.00. The total Oversize Participation cost being requested with this project is $36 ,809 .80 . Please forward this request to the appropriate officials for consideration. Thank you.
