Bicentennial Park

 Bicentennial Park is a neighborhood park located on the north side of Valparaiso, Indiana. The established park contains facilities for softball and basketball, a playground and support facilities such as restrooms and parking.
Lehman & Lehman was originally commissioned in 2009 to assist the Valparaiso Parks Department in a feasibility study on how the current park infrastructure and facilities could be renovated into a new master plan vision. Neighborhood surveys and stakeholder meetings were conducted and data collected, with the result of the study producing five conceptual schemes for consideration.
Funding was secured in late 2012 for the implementation of the master plan and Lehman & Lehman was once again engaged by the City of Valparaiso to develop construction documents for the first two phases of construction.
The first phase of construction consisted of extending utility infrastructure for the future restroom and concession building, reducing the size of the existing softball field, installing new softball fencing and constructing compacted aggregate pathways. The second phase of construction began in the spring of 2013 with major earthwork to help with drainage and overall stormwater retention within the park and adjacent neighborhood in addition to establishing the base elevations for a future softball diamond.
Lehman & Lehman worked closely with the Valparaiso Park Department as well as the City's Engineering and Stormwater Departments. deBoer Egolf Corporation of Portage, Indiana was the contractor for the project workscope, which was completed in June, 2013.
Below are photos of the construction process showing most recent first and going to pre-construction.
