ALTERNATIVES The following alternatives for surveying, engineering design, permitting, preparation of assessment rolls, and public hearing notification are presented: Alternative No. 1 Surveying - At the present time, an existing vacancy in a Party Chief position has limited in-house survey capabi- lities. If the position is filled quickly, the County Survey crews anticipate that the construction stake -out of Florida Ridge Subdivision and Dixie Heights Subdivision (8.3 miles of roadway) would take approximately 9 months. Two applicants for this position appear qualified, and we anticipate hiring soon. These projects will consume 30% of our surveying resources. Unexpected projects have historically demanded 20% of the crews time. Other scheduled projects will consume 40% of the crews time. In the next 2 months, the County crews can survey six of the above 21 projects. Since six of the above projects have survey complete, there remains nine projects that outside surveying is required. Staff recommends that all surveying of the remaining nine projects be contracted out to local consultants using our Continuing Contracts already in effect. It is estimated that a typical project would cost $2000 for outside surveying. For nine projects, the estimated cost is $18,000 for surveying. Engineering Design - Currently, the Dixie Heights Petition Project is being designed in-house. It is projected that this project will be complete June 30, 1989. This will consume all of our design resources. As a result, staff recommends that final design, stormwater permitting and other permitting as necessary, summary of quantities, and cost estimates be contracted out to local engineering firms using our Continuing Master Agreements. It is- estimated that engineering design for a typical project would cost as follows: Original layout & drafting 60 hrs. @ $35/hr =$2,100 Design by Project Engineer 40 hrs. @ $60/hr =$2,400 Permitting 24 hrs. @ $60/hr =$1,440 Contract Doc., Spec., Cost Est. Summary of Quantities and Reimbursibles 16 hrs. @ $60/hr =$ 960 $6,900/ each project 58
