PHILADELPHIA, PA (RETROFIT DESIGN) - Rodriguez Consulting LLC (Rodriguez), provided retrofit design to fix the existing conditions of 2198 Hornig Road to comply with Philadelphia Water Department (PWD) requirements and propose new best management practice (BMP) solutions in order to receive additional stormwater credits.
An existing stormwater detention basin was located on the property which the Client desired to obtain stormwater credit from the Philadelphia Water Department for the amount of stormwater managed through it. In addition, the Client wanted to determine if the basin could manage additional stormwater from the roof of the existing building or from the eastern parking lot.
Rodriguez collected and reviewed existing information on the site to identify existing credit opportunities and made recommendations for retrofits to the stormwater basin for it to obtain stormwater credits based on PWD's criteria.
Examples of information collected are existing site data including topography, utility locations, storm drain system locations (plus size, slope, and material), existing AutoCAD files, existing paper copies of site plans or development plans, and site photos.
This information was reviewed to determine the current capacity of the existing stormwater basin. Further analysis at the site including identification of drainage areas, available open space and green space, location of discharge/overflow points and maintenance access issues were completed.
Based on the analysis performed, Rodriguez made recommendations to the Client on best options for obtaining stormwater credit from the PWD for the stormwater basin. An existing Resources and Site Analysis (ERSA) was prepared and submitted to the PWD to initiate the credit process.
