Updated March 2021! Manual for Hydrologic Calculations within SSCAFCA’s jurisdiction.

Effective immediately, the new guidance should be used to perform hydrologic calculations for any SSCAFCA project. SSCAFCA will continue to accept hydrology calculations based on the current version of the City of Rio Rancho/SSCAFCA Development Process Manual (DPM) for development or capital projects requiring joint SSCAFCA and City approval.  The Manual for Hydrologic Calculations was originally approved by the SSCAFCA Board of Directors in April 2020.
