6.1 Cost Estimating
Itemized cost estimates were developed for each CIP project with an anticipated level of
accuracy of +50% to -30% (order-of-magnitude cost estimates). The cost estimate worksheets
are included in the appendix for reference. The estimates include capital construction costs and
estimates land acquisition. Unit costs were obtained from recent bid tabs and Site Work and
Landscape Cost Data, RSMeansO, and equipment suppliers. Unit costs for pipeline
construction, manholes and inlets include material, excavation, and backfill. Surface restoration
was developed as a separate cost item. Utility relocation cost were developed as a separate
item for sewer line relocations and for watermain lowerings 16" in diameter and greater. Minor
utility relocations including, water and sewer service laterals, were accounted for as an
allowance of the total construction cost. Quantities were for pipes, inlets, manholes, and water
quality facilities were obtained from the project GIS.
The cost estimates also include a 30% construction contingency and an 18% allowance for
engineering and administration. All estimates are in 2006 dollars and equate to an Engineering
News Record, Construction Cost Index of 7880
6.2 Implementation Plan
The goal for this strategic plan is to manage stormwater, by minimizing impacts on localized and
downstream flooding and improving water quality. To these ends, the recommended system
improvements were categorized as 1) Hydraulic and Combined Hydraulic/Water Quality projects
or 2) Water Quality Improvement projects. These two project categories form the collector
system CIP.
The implementation plan for the Hydraulic and Combined Hydraulic/Water Quality CIP projects
follows the Tier 1, 2 and 3 problem areas. Tier 1 CIP projects are considered high priority
improvements as they resolve severe conveyance system problems and in some instances
address stormwater quality problems. Tier 1 projects areas are anticipated to a) have a high
social benefit by resolving street and property flooding issues, b) have a high economic benefit
by reducing flooding risk and property damage, and c) provide an environmental benefit by
addressing stormwater quality issues at identified problem locations. Note that not all Tier 1
locations included a water quality problem site and that the overriding criterion for prioritization
was resolving flooding issues. Table 6.2-1 identifies the Tier 1, Tier 2 and 3 CIP projects.

The implementation plan for the WQIMP projects were prioritized based on problem severity as
identified by pollutant load. The WQIMP category was developed since many of the water
quality project sites were not adjacent to hydraulic problem and improvement locations. In
addition, many of these WQIMP projects could be defined as a small capital projects since the
estimated construction costs are less than $100,000.
