Q: Our office received questions from The Saint Parish Catholic Church staff by Email on April 30th, 2021, to clarify neighboring properties will not be impacted by runoff created by proposed conditions. The Church staff questions are below:
We do have some concerns—largely for our downstream neighbors--that Outfall 1 (or other Outfalls) could be overwhelmed given the channeling of significant new quantities of runoff. Can you help us with understanding the handling capacity of these Outfalls to accommodate the designed for 1-year, 2-year and 10-year storms?
What could happen if we have one of those large storms which surpass the usual thresholds? (I’m thinking of a storm in early July 2019)?

The proposed parking lot in the southeast (SE) corner of the Falls Church High School site conveys a portion of the existing overland flow to the proposed parking area storm pipe system and the StormTech SWM facility. The proposed SWM system will detain the peak flow to levels below the undeveloped good-forested conditions for the 1, 2 and 10-year storm events and satisfies the Fairfax County requirements for SWM and stormwater outfall. The detained flow is piped to the existing storm pipe system near the
