Proposal for CITY OF SOUTH BEND, INDIANA
<br />PROJECT EXPERIENCE: LFA
<br />MICHIGAN STREET/MAIN STREET/MARION STREET ROUNDABOUT,
<br />SOUTH BEND, IN
<br />CLIENT: CITY OF SOUTH BEND
<br />COST: $3.8 MILLION; KEY STAFF: MICHAEL GUZIK, JOE DUNBAR
<br />LFA was selected as part of a design team to develop plans for the north confluence of traffic for City of South Bend’s Two-Way Streets
<br />project for the Smart Streets Initiative. This location was the north boundary of existing one-way traffic that uses Michigan Street for
<br />northbound travel and Main Street for southbound travel.
<br />A roundabout was selected as the most efficient, safest means to move over 20,000 vehicles through this intersection daily, as well as
<br />existing and anticipated increasing pedestrian and bicycle volumes. LFA collaborated with the City of South Bend’s Engineering staff
<br />and Department of Community Investment to develop the preferred geometry and coordinate features within this corridor consistent
<br />with substantial owner input.
<br />The Department of Community Investment worked extensively with a city planning consultant to develop a master plan for the City.
<br />This detailed and comprehensive plan aimed to ultimately make downtown South Bend more attractive to pedestrians, bicyclists, and
<br />consumers, thus spurring revitalization in the City’s center.
<br />LFA and the design team were tasked with translating the master plan into construction drawings complying with applicable standards
<br />(City of South Bend, AASHTO, INDOT). Throughout the design process, the design team incorporated improvements requested by the
<br />client, consistently improving the quality of both the construction documents and the final construction product.
<br />This project was combined with four others for bidding and construction, thus LFA had the opportunity to coordinate project
<br />boundaries, details, specifications and other related items with our project partner as well as at least four other consulting firms involved
<br />in the combined project. As a local presence, LFA provided key support to the City through meetings with individual stakeholders, utility
<br />coordination services, and assisted as needed during the land acquisition process.
<br />IRONWOOD DRIVE, CORBY BOULEVARD, ROCKNE DRIVE INTERSECTION
<br />IMPROVEMENT,SOUTH BEND, INDIANA
<br />CLIENT: CITY OF SOUTH BEND, INDIANA
<br />COST: $3.5 MILLION; KEY STAFF: DMITRI ADAMS , JOE DUNBAR
<br />LFA was selected for this intersection improvement project for a unique five-point intersection on the city’s northeast side. We
<br />performed an engineering assessment to establish the preferred alternative — either a roundabout or signalized intersection. A
<br />signalized intersection was identified as preferred primarily due to single-family home relocations required and context-sensitive
<br />application in this arterial corridor. Beyond signal modernization, this project included a road right sizing application for Corby Blvd. LFA
<br />addressed drainage with separation of the existing combined sewer for storm sewer network discharging to a screened retention basin
<br />off alignment. We also included ornamental lighting, mast arm signals, numerous ADA ramps, sidewalk and driveway reconstruction,
<br />among other amenities for a single-family home neighborhood context. LFA Project team services included topographic survey,
<br />environmental documentation, geotechnical investigation, utility coordination, road plan development, right-of-way engineering, and
<br />real estate services.
<br />MICHIGAN STREET/CHIPPEWA AVE ROUNDABOUT, SOUTH BEND, IN
<br />CLIENT: CITY OF SOUTH BEND
<br />COST: $2.6 MILLION; KEY STAFF: MICHAEL GUZIK, JOE DUNBAR
<br />The LFA-led team was selected to develop design plans for a roundabout at the south gateway as part of the City of South
<br />Bend’s Smart Streets Initiative. This intersection was at the south boundary of one-way traffic that used Michigan Street for north-
<br />bound travel and Main Street for southbound travel, handled over 20,000 vehicles daily. Therefore, design of this roundabout to
<br />both diverge northbound traffic and combine southbound traffic was critical. LFA developed geometry that achieved these
<br />requirements with minimal impacts to surrounding properties.
<br />The design phase involved applying City policies to a concept plan developed for the City’s Department of Community
<br />Investment by a city planning consultant. LFA elevated the concept plan into a design concept and developed three additional
<br />concepts. The City of South Bend, represented by staff from the Departments of Engineering and Community Investment, joined
<br />LFA in vetting alternatives, reviewing each of the four, identifying the controlling criteria, and distilling that information into a
<br />decision matrix. Once complete, the decision matrix was refined into the preferred alternate, which was ultimately developed
<br />into construction documents.
<br />LFA coordinated with four other consulting engineering firms, most of which were located outside of the area. LFA leveraged
<br />our local presence by providing key support to the City through meetings with individual stakeholders, performed topographic
<br />survey, provided utility coordination services, and assisted as needed during the land acquisition process.
