would most likely need to be acquired, and construction costs continue to escalate annually. The funds for this portion of the project would come from the corresponding Trunk Utility Funds and the expenditures are estimated to be approximately $440,000. 2. In looking at segment 1 and the. overall alignment, it may make sense to extend the limits of this project approximately 500' to eliminate the next set of curves located on 166th Avenue immediately to the west of Limonite Street. The proposed overall alignment shows drastic impacts to the home located at 7131166th Avenue NW, mostlikely amounting to a total taking of that property. A conversation was had with the property owners to the south of this lot, at 7100 166th Avenue NW, and they were open to the possibility of right;.of-way acquisition on their parcel to permit the roadway to swing southward and allow all existing homes to remain intact. If this southward roadway swing proves to be the preferred alignment, constructing 166th to Limonite would require the removal of a portion of this newly constructed road when the next segment is contemplated. Until field surveying is completed, the extents of potential impacts are unknown. Staff would like to investigate this option to potentially be included as part of this project. The costs to realign this portion of roadway, not including utility extensions, would also be financed withMSA Funds and are estimated at $120,000 (infrastructure only). These estimated costs may vary depending on field conditions, which is why we are attempting to get a handle on the scope of the project before considerable time is spent gathering field data. It should be noted that the total infrastructure costs (MSA eligible) for segment 1 only are estimated at $675,000. 3. To substantially complete the project this year additional resources are required and we are requesting authorization of consulting services to supplement staff. Current City workload has the engineering staff managing multiple projects throughout the City, making it difficult to remain active on a single project for a prolonged period oftime. Staff has asked Bolton & Menk to provide a proposal to complete the entire project, broken out into distinct tasks, and they have responded with a scope of services totaling $157,500. It is staffs recommendation to authorize a maximum expenditure of $80,000, financed through State Aid funds, to utilize the expertise of Bolten & Menk for preliminary engineering related to property impacts and potential utility extensions, final design and drafting, and administration of the State Aid process. It is our intent to use City staff for the up-front tasks of topographic surveying and land/easement acquisition, bring in the consultant to assist with the drafting/design and State Aid approval process, and then use City staffagain for permitting, construction administration, construction staking, inspections, and record drawings. Staff RecommendationlW ork Plan: Proposed Street Imvrovements We are recommending that 166th/167th Avenue be constructed to MSA standards and that municipal utilities be installed under the roadway (municipal utilities are discussed below). The street is proposed to be constructed to a 9 ton design and have a width of 32 feet; allowing for parking on one side. The goal is to utilize the existing infrastructure to the extent feasible and to install the streets as close to the existing grades (with adjustments to account for surface drainage) and alignment (to limit the impacts to adjacent properties) as possible. A 10' bituminous trail is proposed along the northerly right-of-way line, and storm sewer and ponding will be installed as necessary to accommodate surface drainage through the corridor. Proposed Municival Utilities The sanitary sewer could be extended within the project area from its existing location at the intersection of Limonite Street and 166th Avenue, ap.d would most likely' consist of an 8" PVC -122-.
