It is proposed that the southern por~i0n of the project be connected with that portion of Bison Street N.W. terminating in Tron Brook Ridge subdivision and forming a through street. This connection is controversial. The through connection was recommended by the Planning and Zoning Commission and endorsed by the City Council when Tron Brook Ridge was platted. This through street alignment has also been strongly endorsed by a number of residents in adjacent Golden Eagle Estates as a means of distributing existing and future residential traffic from the route of 171st Avenue N.W./Zeolite Street N.W./168th Avenue N.W., which is predominantly used at this time by local residents who wish to travel southbound on Variolite Street N.W. City Staff has also recommended the through street contiguation as the alternative would result in the creation of two cul-de-sac streets in violation of the City's 600 foot maximum length. On the other hand, residents of Bison Street N.W. south of 171st Avenue N.W. have expressed a strong desire to see the street retain its character as a dead end street. The City Council has also given approval to' this alternative. The City Council received a feasibility study which addressed the cul-de-sac as an alternative for bituminous paving and voted on May 22, 1990 to proceed with the project as a cul-de-sac street. The paving project, however, did not proceed to construction. The southern 350 feet of roadway associated with Project ~t92-23 is nonexistent and the necessary right-of-way, consisting of a 33 foot strip, would have to be acquired from property owners of parcels three and six as shown in Exhibit B. Following paving of the roadway, disturbed areas will be restored with a minimum of four inches of topsoil and be fertilized, seeded and mulched. ESTIMATED PROJECT COSTS The estimated costs for projects ~92-20 and ~t92-23 are presented in Tables 1 and 2, respectively, and include detailed construction costs and overhead costs. Overhead costs include, but are not limited to, engineering, construction staking, inspection, fiscal, legal, administrative and contingencies. Overhead costs for the project are estimated based upon percentages of construction cost. These percentages are estimated as follows: Engineering 10% Staking and Inspection 7% Fiscal and Legal 3 % Administration 5% Contingencies 5 % In addition to the normal construction and overhead costs, it was noted that Project 4~t92-23 will also require the acquisition of a 66 foot strip of fight-of-way 350 feet long. Based upon awards for similar right-of-way acquisition on previous City projects, it is estimated that $3,500 should be allocated for costs incurred due to the fight-of-way acquisition. This amount does not anticipate the cost of eminent domain procedures for acquiring the property (including legal, expert testimony, appraisal fees and commissioner expense). 2
