SEPI is performing sidewalk design and engineering services as part of the City of Durham SW-58 Bike-Pedestrian project group. The project is a LAP funded project and is administered by the NCDOT.

SEPI is providing pedestrian-focused design improvements along Carpenter-Fletcher Road between East Woodcroft Parkway and Alston Avenue. The pedestrian improvements include widening for bike lanes and the installation of curb and gutter with sidewalk.

There are two FEMA stream crossings that will require “No-Rise” or CLOMR submittals. The crossings are of Northeast Creek North Prong and Northeast Creek North Prong Tributary, which are both a part of FEMA’s Special Flood Hazard Zone (AE). This element of the project is especially sensitive as there are multiple insurance structures in the floodplain both up and downstream of the crossings.

SEPI is tasked with providing multi-disciplinary services for this project such as geomatics including planimetric and topographic data and plats for proposed easements or right-of-way as well as environmental investigations including threatened and endangered species assessment, cultural review, and permitting.

Design tasks include roadway, hydraulic, drainage, and erosion control design; traffic engineering includes signal design, traffic control, pavement marking, and signing; and planning services include a Programmatic CE and public involvement. The designs will also include construction plans and bid documents.

In addition, SEPI developed 3D visualization models from which two typical sections/cross sections were made as well as a fly through animation of approximately 0.80-miles for use in public involvement efforts.
