APPENDIX
<br />Baseline Cost Assumptions & Considerations
<br />The costs of creating an urban park vary widely
<br />based on site conditions, design, program and
<br />use. Preliminary construction cost forecasts
<br />presented in Table 1 were developed from a range
<br />of speculated park improvements, and are general
<br />cost assumptions at the very preliminary stages of
<br />the study.
<br />The baseline understanding of typical park
<br />improvement components and rough cost per square
<br />footage were derived from a recent Redwood City
<br />dog park development which yielded a $35 per
<br />square foot cost. Approximate baseline infrastructure
<br />improvement costs include: hardscape removal and
<br />replacement, storm drain relocation and installation,
<br />general landscaping, irrigation improvements, slight
<br />re -grading, and minor utility adjustments.
<br />The typical urban park cost of $65 per square foot
<br />was gathered from Jamison Square in Portland,
<br />Oregon, which includes an interactive water feature,
<br />play area, stone terrace, mature trees, and vendor
<br />areas. A large-scale intensive urban park cost
<br />forecast was taken from the recent City of San Jose
<br />St. James Park competition that yielded a cost of
<br />$110 per square foot for extensive improvements
<br />that included numerous site structures, sculptures,
<br />interactive water feature, and a large playground. It
<br />is recommended that a contractor or cost estimator
<br />review and advise on preliminary probable cost
<br />forecasts provided.

<br />Note:
<br />1. Site areas are provided by SERA Architects and are total approximate site areas, which include developable area
<br />only.
<br />2. Approximate park area for Site 02: Llbrary Campus/ Roselli Park is assumed to exclude existing buildings.
<br />3. Forecasted cost for Site 03: City Hall/ Main Street shown does not include creek daylighting. Refer to Table 4 for
<br />additional potential costs related to daylighting.
<br />4. Refer to Tables 1a -d for additional potable water storage cost information.
<br />5. Cost for the Library site assumes a third of the overall site (52,000sf) would be developed with park
<br />improvements.
