The Stormwater facilities are made up of a patchwork of mini collection systems
constructed as WPA project and/or by City sewer and public works departments.
Most of the systems constructed by City crews used substandard construction
materials and/or design. The systems had never been properly cleaned. OMI was
assigned cleaning and spot
repair responsibility just over three years ago for an operating budget of
$154,900. OMI has a staff of 3 people in the Stormwater Program. City staff has
developed a five year Stormwater capital plant (attached) allocating limited
funds to provide some relief for remaining two of eight flood zones identified
in the Stormwater Runoff Study. The plant includes installation of at least five
injection wells per year. The Utilities Department has developed a vertical
french drain design to address small areas of standing water in an affordable,
cost effective way.
- Established a stormwater
cleaning program to clean the stormwater systems three times per year and as
needed (first time in more than 20 years). As indicated in the attachments,
approximately $160,000 per year for operating budget.
- The City has repaired an
injection well at Duck & 20th and installed 4 new catch
- This project has resolved the
flooding at this location.
- Five year Capital Plan calls
for placement of ten new injection wells per year and continued capital
repairs to the existing collection system as needed. Based on the
information available, it appears that only five wells per year are
- Designed small vertical french
drains that can be installed by OMI for less than $1,500 each. The design
was necessary to enable the City to begin attacking smaller areas of
standing water in a more cost-effective way. The plan was possible because
the Utilities Department received clarification from DEP on permit
- OMI installed the first 10
vertical french drains in an effort to attack the small areas of localized
flooding common throughout town.
