Freese and Nichols was retained to provide park planning services for an aging park in need of a new vision. A critical component of this park planning study was the evaluation and integration of an eroding urban stream into the overall park plan to create an amenity for the park.
Freese and Nichols provided geomorphic assessments along with conceptual planning and opinions of probable construction costs for this stream restoration. To accomplish this, Freese and Nichols performed field visits, delineated drainage areas, developed hydrologic models, calculated shear stresses and coordinated with park planners and Town staff.
The existing three streams across the park site were mostly incised without a natural floodplain. Because the three streams across the park site had small watersheds and steep grades, a step pool design was proposed. This step pool design gave both auditory and visual illusions of a much larger stream that integrated with the peaceful sitting and hiking trails proposed in the park. Renderings and perspectives of the proposed park and stream components were developed to solidify the vision for the park.
Finally, Freese and Nichols evaluated grant funding and regulatory requirements for both the park and stream restoration components of the project. The existing analysis, proposed concepts, renderings and perspectives, budget estimates, regulatory requirements and external funding evaluations were summarized in the Central Park Planning Study as well as presented to council for their approval.
