Safe Routes to School Infrastructure

The Safe Routes to Schools Infrastructure project improved pedestrian access around Cumberland Elementary School and Happy Hollow Elementary School.

Cumberland Elementary School improvements include two crosswalks along Cumberland Avenue, new curb ramps and sidewalks, and solar-powered flashing school zone beacons. One crosswalk was relocated to improve its visibility to vehicular traffic leaving the school parking lot. Surface sidewalks were constructed to provide connectivity between the walkways on the campus and street.

Happy Hollow Elementary School updates include three crosswalks. These crosswalks were improved by constructing new curb ramps, crosswalk pavement markings, and solar-powered flashing school zone beacons. A crosswalk on New Salisbury Street is in the middle of a steep vertical grade, so the flashing beacons provide advanced warning and security for the students crossing at this location.
The flashing beacons used at each school are programmable to allow school personnel to adjust the timing for those days when school has a special schedule.

These improvements were recognized in an award received by the City of West Lafayette for the benefits from utilization of Safe Routes to Schools funding.

Grid Modernization

HWC provided design and construction inspection services for the $1.9 million Grid Modernization Project in the Downtown Corridor of New Albany, Indiana.

The project began with a conceptual study that evaluated past recommendations, identified three options for the one-way to two-way grid modernization, and identified three complementary projects for the downtown corridor. HWC studied options for grid corridor modernization, and the chosen option included converting Spring, Market, Elm, Pearl, and Bank streets to two-way traffic. This option manages vehicle patterns, improves access to downtown businesses, calms traffic, improves pedestrian safety, provides bike lanes, and enhances the economic vitality of downtown businesses.

The project included the modernization of 15 traffic signals through the project corridor and upgrades pavement markings and signage for two-way traffic. The identified complementary projects include downtown streetscape improvements, one-way to two-way conversions west of State Street, and a downtown pedestrian bicycle plan.

Water System Improvements

HWC provided planning, design, and construction inspection services on this water system improvement project, which included a system evaluation for a city of 3,600 citizens.

Improvements included a 500,000 gallon elevated storage tank, a pumping station upgrade, a distribution supply system upgrade (20,000 LF of 6”, 8”, & 12” mains and appurtenances), and upgrades implemented a two-zone pressure system utilizing the new elevated tank and an existing ground storage reservoir. The total construction cost was $2.1M.

Princeton, IN

Water Treatment Facility Improvements

HWC completed an SRF Preliminary Engineering Report for the City’s water treatment facility.  Improvements to the capacity and replacement of antiquated equipment and processes included:

  • 3 new 1,000 gallon per day aerators and a 3rd aerator/detention basin
  • Replacement treatment pumps with variable frequency drives
  • New 500,000 gallon ground storage tank and new high service pumping station
  • New filter backwash waste holding basin to eliminate the existing process of recycling backwash wastewater
  • New SCADA controls system for improved efficiency and reliable supply 

Project Highlights:

  • One million gallons of additional water storage for the system
  • Increased capacity of the plant to 3.0 MGD
  • Replacement of existing high service pumps with two sets of pumps to reduce the high pressure required of the existing pumps which conveyed flow through the filters and into the system
  • Modifications at the treatment plant to replace antiquated equipment and allow for future expansion if necessary
  • HWC completed all facility evaluations, planning, design, bidding, and construction management phases
  • Construction cost of $4.5 million (funded by an SRF loan and an IOCRA DR II grant)
  • Construction completed in 2011

Water System Improvements

HWC provided planning, design, bidding, and construction management phases for this water system improvement project.  The improvements to the system were determined through an SRF Preliminary Engineering Report (PER) completed by HWC in 2009. The items of concern that were evaluated in the PER were a reduction in well capacity, the deteriorating condition of an existing elevated tank, inadequate flow provided near the I-70/SR-59 interchange, the lack of centralized control/monitoring abilities of the system, areas with old and undersized water mains, and sections of aging hydrants and meters.

Project Highlights:

 

  • New 700 gallon per day well in the existing wellfield
  • Replacement 750,000 gallon elevated water tank in the City
  • New 250,000 gallon elevated water tank near the I-70/SR-59 interchange
  • A booster station with variable frequency drives for the 250,000 gallon tank, along with a backup generator
  • New SCADA system at the water treatment plant to monitor/control the plant, elevated tanks, wellfield, and booster station
  • Replacement of 23,000 LF of water main, 100 hydrants, and 1,000 meters
  • Project bid in Spring 2010 in 5 divisions
  • Construction cost – $6.0M (funded by an SRF loan and an IOCRA DR II grant
  • Construction completed in December 2011
