ADDITIONAL
INFORMATION:
The USDA-NRCS
operates the EWP program with the stated purpose of undertaking “emergency
measures for soil erosion prevention to safeguard lives and property from
floods, drought, and the products of erosion on any watershed whenever fire,
flood, or any other natural occurrence is causing or has caused a sudden
impairment of the watershed.”
During and subsequent
to the heavy rains and flooding in June 2008, severe soil erosion and
landslides occurred near 1706 Pennsylvania Avenue. On October 14, 2008, the City submitted an
application to the USDA-NRCS EWP for assistance at 1706 Pennsylvania
Avenue. The City’s role in the EWP
program is to act as the governmental sponsor for prevention and repair
projects.
The EWP program will fund 75% of the
project cost with a 25% local share paid per agreement with the
property owners.
City staff has met with the NRCS
representatives at the property site to assess the damage and estimate the
repair costs. A Damage Survey Report
(DSR) prepared by the NRCS includes the construction of slope stabilization on
the property with an estimate for construction at $127,500. The project cost including design,
construction administration, and easement cost is estimated at $170,000.
Actual project costs of construction will be determined after the
project is completed, and payment arrangements for reimbursement of the City’s
cost-share associated with the project have been negotiated by City staff and
the property owners. The property owners
have provided a temporary easement for construction and construction related
activities, and an easement for operation and maintenance of the slope
stabilization at no cost to the City. In
addition, a temporary construction easement has been acquired from the
adjoining property located at 1624 Pennsylvania Avenue, which is owned by James
M. Cummings and Dana L. Danley.

Engineering Department has prepared plans, specifications, form of contract
documents, and City Engineer’s estimate for the construction of the 1706

nailing with the necessary appurtenances and restoration; in accordance with
