Tom, The amounts owed by UDR and DISD were calculated based on a proration of the total cost of Spring Valley Road improvements ($2,477,827.40) by running feet. UDR agreed to pay one-third of the cost of “Section 1B” (see attached Exhibit “D”). Section 1B is 539 ft in length. At a cost of $1,776.22 per foot, the total for Section 1B is $957,382.77. UDR agreed to pay one-third of this cost: $319,127.59. We prorated the total cost of the improvements, including pavment, associated sidewalks and landscaping. I have attached Exhibit “D” and the bid tab for Spring Valley. Let me know if you need additional information to give to UDR. Thanks!
