Development Process Manual

On April 16, 2020, the SSCAFCA Board of Directors adopted an Updated 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 Development Process Manual for development or capital projects requiring joint SSCAFCA and City approval.


Hydrology Manual Appendices can be downloaded HERE

SSCAFCA prepared the Drainage, Flood Control and Erosion Control portion of the Development Process Manual (DPM) using the City of Albuquerque’s as a guide. This effort was undertaken at the request of the City of Rio Rancho in their effort to prepare their own DPM. Input from the private sector and City staff from Rio Rancho were welcomed and taken into consideration. The major addition to the DPM is the inclusion of HEC-HMS modeling capability. The comment period was open for 30 days from June 5, 2009 to July 6, 2009 during which one comment was received and acted upon prior to adoption by the Executive Engineer on July 31, 2009.

Drainage Policy

All land proposed for development within SSCAFCA’s jurisdiction must meet the drainage requirements of SSCAFCA’s Drainage Policy.

Except as permitted by this policy, the natural topography, drainage pattern and perviousness of any lot, tract or parcel of land within the territory of the Authority may not be altered by grading, filling, excavating, or subdividing.

No plat, replat, summary plat, development plan or subdivision of any land within the territory of the Authority may be approved by the governing authority of a public body without SSCAFCA’s written approval. Applications for plat, summary plat, replat, development plan, or subdivision approval filed with any public body must be accompanied by certain submittals to SSCAFCA, as spelled out in SSCAFCA’s Drainage Policy.

Key Submittal Guidlines

1.  Submit a Drainage Information Sheet with each submittal.

2.  Submit one of the following meeting the requirements outlined in the SSCFCA Policy and Section 8 of the SSCAFCA Development Process Manual (DPM):

Conceptual Grading and Drainage Plan (5+ Acre Developments)
Drainage Report (Development within a floodplain and/or 10+ Lot or 5+ Acre Subdivisions)
Grading and Drainage Plan (Developments of 5 Acres or Less)

  • All Grading and Drainage Plans (Checklist here) and Drainage Reports (Checklist here) should include the appropriate checklist with each submittal.
  • Grading and Drainage Plan submittals should also include plan and profile information for storm drain design.
  • Drainage plans for development must comply with applicable Authority/City planning documents.

3. Development must provide all required right-of-way (ROW) to accept and convey developed conditions upland
flows (as outlined in existing drainage/watershed master plans, if available) through the proposed development to
publicly owned facilities that have sufficient capacity and protection to accept these flows.

  • The developer is responsible for constructing all offsite improvements along with the development or financially guaranteeing offsite improvements.
  • Interim improvements are required until the permanent improvements are in place.
  • Discharge of runoff to public ROW must be in a non-erosive manner, or improvements made to public ROW to prevent damage, including unimproved roadway ROW. Discharge to NMDOT ROW requires NMDOT review and approval.

4. If development is located within the lateral erosion envelope (LEE), development must provide an engineering analysis outlining measures to protect the development.

5. Identify proximity of proposed development to FEMA mapped floodplains and major arroyos.

6. Developed-conditions site runoff should be restricted to historic discharge rate or less (subject to downstream

7. Provide for water quality treatment of runoff per Section 10 of the SSCAFCA DPM prior to discharge from site.

8. A development agreement is required per SSCAFCA Policy, subject to the discretion of the Executive Engineer.

9. Meeting with SSCAFCA may be required to discuss potential additional requirements prior to proceeding with
additional design work. It is recommended that this meeting occur as early as possible, even prior to obtaining a
land contract. These requirements include, but are not limited to:

  • Location of proposed development and proximity to nearest drainage conveyance, i.e., arroyo
  • Potential conflicts with future flood control facility locations
  • Acceptable discharge locations
  • Recognition of environmental concerns
  • Determination if protective measures are necessary if development is located near drainage way/arroyo
  • Requirements of the applicable regional/local watershed management plan
  • Preliminary project schedule
  • Receipt of SSCAFCA submittal process packet (checklist, etc.)
  • Acknowledgment of SSCAFCA ROW acquisition process (see Real Property Acquisition Info Booklet)

10. Acceptance and approval by SSCAFCA does not relieve the developer and/or its agent of the ultimate responsibility for the infrastructure design to adequately protect and serve its intended purpose. Each phase of development must be reviewed and approved by SSCAFCA. Development approvals given by SSCAFCA are valid for 1 year from start of construction.
