Maintenance Resources Introduction
practices (STPs) need frequent maintenance to function properly over time.
While maintenance has long been recognized as an important component of STP
performance and longevity, it has frequently been neglected. Often, communities
do not have the infrastructure in place to track, let alone maintain, the proliferation
of STPs throughout their communities. With the implementation of NPDES Phase
II, STPs will be more widely implemented, creating an even greater need for
consistent and frequent inspection and maintenance. In order to meet this challenge,
the stormwater manager needs a suite of tools at his or her disposal, from legal
authority to inspect and maintain STPs to educational materials for maintenance
of privately owned STPs.
This web site offers some
of the key components of a successful maintenance program:
- Pond and Wetland Maintenance Guidebook - Draft September 2004 PDF (3.6MB)
This guidebook provides guidance for maintenance considerations associated with ponds and wetlands during the design, construction, and postconstruction phases aimed at minimizing the burden of long-term maintenance.
The primary audience for the Guidebook is Phase I and Phase II NPDES communities and provides the inspector, program manager, designer, and owner (i.e., responsible party) with an understanding of common stormwater pond and wetland maintenance problems and possible solutions.
- Inspection and Maintenance Ordinance Language
The ordinance language establishes the legal authority to inspect STPs, and outlines timelines and penalties for improper maintenance.
easements establish the right of a community to enter private property to
access an STP for routine maintenance or inspection.
bonds are a financial arrangement used to finance final construction or maintenance
of an STP in the event of contractor default.
Agreements and Arrangements
stormwater maintenance agreement is a formal contract between a local government
and a property owner designed to guarantee that specific STP maintenance functions
are performed in exchange for permission to develop that property.
Tracking System Options
community's tracking system records details about the condition and maintenance
track record of STPs on the ground.
unit costs provided in this section can be used to estimate the financial
burden associated with both repairing existing STPs and conducting routine
maintenance. Included in this section is a table of maintenance to help communities
develop maintenance budgets based on the types of STPs owned.
section describes typical frequency of inspection and repair items for STPs.
These frequencies can be used to tailor inspection programs, and also used
in conjunction with routine costs to estimate the overall program costs of
Inspection Checklists, Reminders and Notifications
section provides example checklists that identify routine STP inspection items.
The checklists highlight the key items that need to be inspected during regular
visits. When a routine maintenance inspection reveals a problem, the STP owner
needs to be contacted and given a timeframe within which to complete repairs.
Some example letters are included within this section.
Maintenance Education Materials/Links
many STPs are privately held, either by commercial property owners or homeowners'
associations, educational materials can supplement a routine inspection program
by alerting owners to routine STP maintenance needs.
