DSR ID# 21532; Napa Creek - Stream Embankment Restoration

Cross-Reference: Eligible facilities, Codes and Standards
Summary: Flooding in 1995 caused erosion along Napa Creek upstream of the Pearl Street crossing. The areas of erosion were at the ends of retaining walls on both sides of the creek and along 125 feet of the eastside of the stream upstream of the retaining wall. DSR 21532 was written for $17,771 for the restoration of the erosion with unclassified fill covered with fabric and riprap for slope protection. It was determined that the natural stream is not eligible for permanent restoration, as it was not an improved property. However, two areas of erosion at the ends of the retaining walls were eligible. The city did not have an adopted standard to repair eroded banks with riprap, thus the eligible scope of work was reduced to reflect the repair the eroded areas at the ends of the retaining walls with unclassified fill. The funding for DSR 21532, calculated to be $176, was deemed ineligible, as it was less than $1000. The first appeal was denied because the natural stream bank does not qualify for permanent restoration, as it is not an eligible facility. Further the Region stated that the City of Napa did not have a written, adopted standard for repairing eroded stream banks, and the restoration did not qualify as an emergency protective measure, as there was no immediate threat to life, public health, safety, or damage to improved property.
Issues: Should FEMA repair the erosion in the vicinity of the retaining wall with riprap?
Findings: No. The areas were not protected with riprap prior to the disaster and there is no adopted standard that would require such work.
Rationale: For costs associated with an applicant's standard, which change the construction of the facility, such standards must be in writing and formally adopted by the applicant prior to project approval. The city does not have a written adopted standard for repairing eroded areas with riprap. This also applies to the proposed concrete/stone transition area. Accordingly, funding is not available.
