Nall Avenue, 117th Street & Town Center Drive Improvements
Phelps Engineering prepared and completed construction plans for additional through lanes, turn lanes, medians, and other geometric and traffic improvements to Nall Avenue, 117th Street, Town Center Drive and Roe Avenue in Leawood, Kansas. The project also included streambank stabilization, trails and major storm sewer improvements.Significant engineering challenges included:
Utility relocations (KCP&L, Time Warner, AT&T, Kansas Gas, City Storm, JCW Sanitary Sewers)
Designed Nall turn lanes to avoid large diameter water main.Coordination of traffic signal modifications at 3 intersections.
Traffic control phasing designed to minimize construction impacts to local businesses.
Funding required the project to be split into three bid packages.
PEI completed engineering surveys and street reconstruction design plans for the City of Oalthe Public Works Dept. These projects were in an established residential neighborhood, and involved removal and replacement of existing curb and guttered streets with a new street section. In some locations, the design grades were adjusted to improve yard drainage or driveway slopes. In other locations, it was critical to match existing curb grades to minimize property disturbance. Sidewalk and ADA replacement and utility coordination were also critical components of this project. PEI also facilitated a public meeting to introduce the project to the adjacent home owners, and held on-site meetings to obtain easements.
Leawood Residential Streets Program
PEI completed engineering surveys and street reconstruction design plans for the City of Leawood Public Works Dept. These projects were in an established residential neighborhood, and involved removal and replacement of existing curb and guttered streets with a new street section. In many locations, the design grades were adjusted to improve yard drainage or driveway slopes. In other locations, it was critical to match existing curb grades to minimize property disturbance. New storm sewers were constructed in the area, as the existing neighborhoods had minimal existing storm drainage infrastructure. Acting as an extension of City’s staff, PEI prepared plans for one large neighborhood (which included 4 streets), while the City prepared plans for two other neighborhoods. The plans were merged and bid out under the City’s procurement process.
Delaware Street-Historical Streetscape
PEI was selected by the City of Independence, Missouri to provide the surveying, engineering design and public relations services for the Delaware Street Restoration project. This historic street was transportation enhancement funds from MoDOT, which required strict conformance to federal contracting requirements and procedures. The project created a safe walking environment while retaining the historic integrity of one of the nation’s most culturally significant streets.
Improvements included replacing the failing, patched curb with new concrete curb that was textured and colored to match the original limestone curbing. Concrete sidewalks were replaced with colored and textured walks that mimicked the original hexagon pattern walks used by Truman himself. Other improvements included buring overhead power lines, storm sewers, and street resurfacing.
A significant challenge on the project included designing the new improvements to meet current City requirements while meeting historic preservation requirements. Another significant component to the project included holding public information meetings to gather input from the longtime residents and community leaders, and then present plans for the project to City Council.
2nd-3rd Street Connector
The City of Grandview has contracted with PEI for the design of a new 31-foot wide collector road to serve existing commercial and industrial businesses on the West side of Grandview. The project is approximately 3,600 linear feet and includes re-construction of an existing two lane ditch section road for approximately one-half the project length and a new alignment through existing properties for the remainder.
The project is partially funded under the American Recovery and Reinvestment Act (ARRA) and required MoDOT review and approval. Additionally, the project documents were prepared in two phases for purposes of bidding MoDOT approved ARRA funded work in the first phase, before all of the right of way for the second phase could be acquired.
Particular challenges included road alignments, storm drainage and utility design in an existing, well-established area and construction traffic control. The project will be constructed in 2010.
Glen Eagles Roundabout
Overland Park, KS
Phelps Engineering, Inc. prepared residential street, storm sewer, sanitary sewer and street light plans. Phelps Engineering, Inc. teamed with Alternate Street Design, P.A. to design a roundabout located at 141st Street and Bluejacket.
159th ST., Lackman to Pflumm, Jo.Co., KS
The PEI team successfully completed the design for reconstruction of a 1 mile section of 159th Street between Pflumm Road and Lackman Road. The project included pavement widening, shoulder addition, ditch grading, storm sewer and utility coordination for a 2 lane arterial roadway, which was jointly funded by Johnson County, Kansas and the City of Olathe, Kansas. 159th Street is an arterial road that serves residential development, large-lot rural homes, commercial business and Heritage Park. Due to the limited space adjacent to the park and residential homes, careful planning was required in order to maintain positive drainage in the roadside ditches.
