Our team provided engineering design and survey services to the City of Roxboro for this LAPP project funded by a Congestion Mitigation and Air Quality (CMAQ) grant through NCDOT. The original intersection of Chub Lake Street with Ridge Road and Crestwood Drive had an offset configuration located at the top of a large crest vertical curve. Limited sight distance, off set turning patterns and limited capacity led to a poorly performing intersection. Left turn congestion, particularly peak hour, was magnifying an inherent safety problem related to the offset configuration. The initial project scope included adding a left turn lane onto Chub Lake Road from Ridge Road, signalization and improved intersection geometrics. However, during right of way acquisition coordination, the city was able to purchase an adjacent parcel in its entirety thus allowing for roadway realignment to eliminate the intersection offset. Summit assisted the city with ROW/easement assessments and platting.
As lead engineer, our team is providing roadway design, hydrologic/hydraulic analysis, drainage design, TMP/PMP design, utility coordination and design, surveying, geotechnical engineering and project management for 28 bridges and 26 culverts. Summit is also managing subconsultant services for structure design, hydraulic analysis/ design, utility coordination and ROW acquisition.
Summit was the prime consultant on the Town of Hillsborough’s Riverwalk, a recently-opened collection of urban greenways along the historic Eno River. To develop the initial greenway routing and bridge crossing locations, Summit and its team performed site assessments, detailed surveys, flood plain analysis, historical and archaeological assessment, and agency coordination to gain concurrence on the preferred route. Under supplemental contracts, Summit provided detailed engineering design including greenway trail design, hydraulic design, CLOMR/LOMR, and structure design to develop full construction plans, prepare bid packages, and administer the public bid processes for the resulting two construction projects. During construction, Summit also provided daily inspection and testing services and construction management of the project to final completion. Summit’s ingenuity to utilize a top down construction method saved the town $30,000, shortened construction time by three months, and preserved mature, native trees.
