EHRA planners, hydrologists and landscape architects worked together to propose an alternative use for the space, re-developing the basin into an amenity pond. EHRA carefully selected native plant materials for both their ability to survive in the harsh conditions of the basin as well as providing filtration for improved storm water quality.
EHRA performed preliminary drainage area delineations for nine creek crossings and calculated approximate 100-year flows for each culvert crossing. Culvert structures were sized for each of the six crossings, ranging from 48” round pipe culverts up to dual 5’x5’ box culverts.
EHRA offered its Landscape Architectural services to complete a Parks and Trails Master Plan for the District.
EHRA was selected by the client to provide engineering design and to serve as District Engineer for the 2,400 acre Towne Lake Development. Our survey department retraced the overall boundary and performed a topographic survey of the site.
Identified as a top priority during the development of the District’s Parks Master Plan, this portion of trail was the first phase of over two miles of planned trails to provide connectivity and recreation for District residents.
EHRA’s own Assistant Project Manager, Mehrafarid Ghoreishi, Ph.D., P.E., received the FHWA-NHI-130056 Safety Inspection of In-Service Bridges for Professional Engineers certification.
This is a training course that includes a bridge inspection field trip; instruction on critical findings along with their identification and response; curriculum on the new AASHTO Element level evaluation; and new activities to maximize engagement.
According to the National Highway Institute, participants will be able to:
Congratulations to Mehrafarid on becoming a Certified Bridge Inspector.
