treat stormwater on the Property. On-site BMPs include dispersion and infiltration devices,
bioretention, permeable pavements, rainwater harvesting systems, tree retention credit,
reduced impervious surface footprint, vegetated roofs and other measures designed to mimic
pre-developed hydrology and minimize stormwater runoff on the Property.
2.City of Renton shall have the right to ingress and egress over those portions of the Property
necessary to perform inspections of the stormwater facilities and BMPs and conduct
maintenance activities specified in this Declaration of Covenant and in accordance with the
Renton Municipal Code. City of Renton shall provide at least thirty (30) days’ written notice to
the Owners that entry on the Property is planned for the inspection of drainage facilities. After
the thirty (30) days, the Owners shall allow the City of Renton to enter for the sole purpose of
inspecting drainage facilities. In lieu of inspection by the City, the Owners may elect to engage
a licensed civil engineer registered in the state of Washington who has expertise in drainage to
inspect the drainage facilities and provide a written report describing their condition. If the
engineer option is chosen, the Owners shall provide written notice to the City of Renton within
fifteen (15) days of receiving the City’s notice of inspection. Within thirty (30) days of giving this
notice, the Owners, or engineer on behalf of the Owners, shall provide the engineer’s report to
the City of Renton. If the report is not provided in a timely manner as specified above, the City
of Renton may inspect the drainage facilities without further notice.
3.If City of Renton determines from its inspection, or from an engineer’s report provided in
accordance with Paragraph 2, that maintenance, repair, restoration, and/or mitigation work is
required to be done to any of the drainage facilities, City of Renton shall notify the Owners of
the specific maintenance, repair, restoration, and/or mitigation work (“Work”) required
pursuant to the Renton Municipal Code. The City shall also set a reasonable deadline for the
Owners to complete the Work, or to provide an engineer’s report that verifies completion of
the Work. After the deadline has passed, the Owners shall allow the City access to re-inspect
the drainage facilities unless an engineer’s report has been provided verifying completion of
the Work. If the Work is not completed within the time frame set by the City, the City may
initiate an enforcement action and/or perform the Work and hereby is given access to the
Property for such purposes. Written notice will be sent to the Owners stating the City’s
intention to perform such Work. This Work will not commence until at least seven (7) days after
such notice is mailed. If, within the sole discretion of the City, there exists an imminent or
present danger, the seven (7) day notice period will be waived and Work will begin
immediately.
4.The Owners shall assume all responsibility for the cost of any Work, or any measures taken by
the City to address conditions as described in Paragraph 3. Such responsibility shall include
reimbursement to the City within thirty (30) days of the receipt of the invoice for any such Work
performed. Overdue payments will require payment of interest at the maximum legal rate
allowed by RCW 19.52.020 (currently twelve percent (12%)). If the City initiates legal action to
enforce this agreement, the prevailing party in such action is entitled to recover reasonable
litigation costs and attorney’s fees.
5.The Owners are required to obtain written approval from City of Renton prior to filling, piping,
cutting, or removing vegetation (except in routine landscape maintenance) in open vegetated
stormwater facilities (such as swales, channels, ditches, ponds, etc.), or performing any
alterations or modifications to the drainage facilities referenced in this Declaration of Covenant.

MAINTENANCE INSTRUCTIONS FOR A RAIN GARDEN
Your property contains an on-site BMP (best management practice) called a “rain garden,” which was
installed to mitigate the stormwater quantity and quality impacts of some or all of the impervious or
nonnative pervious surfaces on your property.
Rain gardens include vegetated closed depressions (ponds) that retain and filter stormwater from an
area of impervious surface or nonnative pervious surface on your property. The soil in the rain garden
has been enhanced to encourage and support vigorous plant growth that serves to filter the water and
sustain infiltration capacity. Depending on soil conditions, the rain garden area may have water in it
throughout the wet season and may overflow during major storm events. This on-site BMP shall be
maintained per Appendix A of the City of Renton’s Surface Water Design Manual.
MAINTENANCE RESTRICTIONS
The size, placement, and design of the rain garden as depicted by the site plan and design details must
be maintained and may not be changed without written approval from the City of Renton or through a
future development permit from City of Renton. Plant materials may be changed to suit tastes, but
chemical fertilizers and pesticides must not be used.
INSPECTION FREQUENCY AND MAINTENANCE GUIDELINES
Rain gardens must be inspected annually for physical defects and sediment accumulation.
Rain gardens have inflow and overflow inlets and outlets. These need to be maintained to
ensure that water is moving into and out of the rain garden. Check inlets/outlets for
debris/sediment blockage, bare spots (exposed soil), or other signs of erosion damage (soil
movement). Remove debris and obstructions as necessary.
After major storm events, the system should be checked to see that the overflow system is
working properly and sedimentation is not occurring at the inlet. If erosion damage or bare
spots are evident, they should be stabilized with soil, plant material, mulch, or landscape rock.
Sediment deposits should be carefully removed and the sediment source eliminated.
Plants must be adapted to wet winter conditions and dry summer conditions. Vegetation is to
be watered and pruned as needed.
Frequent watering is required to keep the plants healthy:
o Year 1: weekly,
o Year 2: bimonthly,
o Year 3: bimonthly,
o Year 4 & beyond: as needed for established plantings and dry periods.
Chemical fertilizers and pesticides must not be used.
Soil must be replaced in areas where sediment accumulation is preventing adequate infiltration
of water through the soil.
Compacted soil should be decompacted.
Trash and debris must be removed often from the rain garden depression.
EXHIBIT B - OPERATIONS AND MAINTENANCE
Mulch must be applied to bare soil at a minimum of 2 inches to maintain healthy growth.
Compost may be added if soil nutrients are no longer adequate to support plant growth.
Vegetation should be maintained as follows:
1) Replace all dead vegetation as soon as possible;
2) Remove fallen leaves and debris as needed;
3) Remove all noxious vegetation when discovered;
4) Manually weed without herbicides or pesticides;
5) To protect infiltration performance, do not compact soils in the bioretention cell with heavy
maintenance equipment and/or excessive foot traffic;
6) During drought conditions, use mulch to prevent excess solar damage and water loss.
RECORDING REQUIREMENT
These rain garden on-site BMP maintenance and operation instructions must be recorded as an
attachment to the required declaration of covenant and grant of easement per Requirement 3 of
Section C.1.3.4 of the City of Renton Surface Water Design Manual. The intent of these instructions is
to explain to future property owners, the purpose of the BMP and how it must be maintained and
operated. These instructions are intended to be a minimum; the City of Renton may require additional
instructions based on site-specific conditions. See the City of Renton’s Surface Water Design Manual
website for additional information and updates.
