Declaration of Covenant
EXHIBIT B
MAINTENANCE INSTRUCTION FOR REDUCED IMPERVIOUS SURFACE CREDIT
Restricted Footprint
Your property contains a stormwater management flow control BMP (best management
practice) known as "restricted footprint," the practice of restricting the amount of
impervious surface that may be added to a property so as to minimize the stormwater
I
runoff impacts caused by impervious surface. The total impervious surface on your
property may not exceed 3 313 square feet without written approval either
from the City of Renton or through a future development permit from the City of
Renton.

Declaration of Covenant
EXHIBIT B
MAINTENANCE INSTRUCTION FOR PERMEABLE PAVEMENT
Your property contains a stormwater management flow control BMP (best management
practice) called "permeable pavement," which was installed to minimize the stormwater
quantity and quality impacts of some or all of the paved surfaces on your property.
Permeable pavements reduce the amount of rainfall that becomes runoff by allowing
water to seep through the pavement into a free-draining gravel or sand bed, where it
can be infiltrated into the ground.
The type(s) of permeable pavement used on your property is: ❑ porous concrete, ❑
porous asphaltic concrete,X permeable pavers, ❑ modular grid pavement.
The area covered by permeable pavement as depicted by the flow control BMP site plan
and design details must be maintained as permeable pavement and may not be changed
without written approval either from the City of Renton or through a future
development permit from the City of Renton.
Permeable pavements must be inspected after one major storm each year to make sure
it is working properly. Prolonged ponding or standing water on the pavement surface is
a sign that the system is defective and may need to be replaced. If this occurs, contact
the pavement installer or the City of Renton for further instructions.A typical permeable
pavement system has a life expectancy of approximately 25-years. To help extend the
useful life of the system, the surface of the permeable pavement should be kept clean
and free of leaves, debris, and sediment through regular sweeping or vacuum sweeping.
The owner is responsible for the repair of all ruts, deformation, and/or broken paving

C.2.6.4 PERMEABLE PAVERS
Permeable pavers provide a solid surface hut allow natural drainage and migration of water into the earth
by permitting water to drain through the spaces between the pavers. On the Internet,there are a number of
manufacturers and installers.
Uses: Sidewalks,patios,parking areas,and driveways.
Design Specifications
Same as for porous concrete,except that the compressive strength specifications do not apply and the
pavement thickness shall he as specified by the manufacturer or a civil engineer-,
•
C.2.6.2 POROUS CONCRETE
Porous concrete consists of a mix of aggregate,cement paste,water and admixtures,but contains less tine
aggregate than conventional concrete. Voids in the hardened concrete allow water to drain through the
surface into the subgrade.
Uses: Sidewalks,patios,parking areas,and driveways.
Design Specifications
A minimum of 6 inches of free-draining sand or gravel base is required under the porous concrete
surface.
• 2. The free-draining base shall have less than 5°1)fines(material passing the#200 sieve)based on the
fraction passing the#4 sieve, •
3. The porous concrete pavement shall be permeable enough to absorb water at a minimum rate of 10
inches per hour immediately after the pavement surface has been wetted continuously for at least 10
minutes. Compliance with this minimum rate shall be checked prior to construction approval of the
pavement. Compliance may be checked using a simple bucket test in which 5 gallons of water arc
poured onto the pavement surface all at once from a 5-gallon bucket. If nothing but a scant amount of
water puddles or runs off the surface,then the pavement is considered to meet the minimum rate of
absorption. If this test is not conclusive,then a 6-inch ring sealed at the base to the pavement surface
shall be used to measure the actual rate of absorption.
4. Porous concrete sidewalks placed in County road right-of-way(note that a road variance is requfred
for cued placement)or on private property subject to vehicle loading shall be-a minimum of 5 inches
thick and shall have a minimum 28-day compressive strength of 3000 psi.
5. Sidewalks and patios on private property not subject to vehicles shall be a minimum of 4 inches thick
and should have a minimum 28-day compressive strength of 2000 psi.

Declaration of Covenant
EXHIBIT B
MAINTENANCE INSTRUCTION FOR BASIC DISPERSION
Your property contains a stormwater management flow control BMP (best management
practice) called "basic dispersion," which was installed to mitigate the stormwater
quantity and quality impacts of some or all of the impervious surfaces or non-native
pervious surfaces on your property. Basic dispersion is a strategy for utilizing any
available capacity of onsite vegetated areas to retain, absorb, and filter the runoff from
developed surfaces. This flow control BMP has two primary components that must be
maintained: (1)the devices that disperse runoff from the developed surfaces and (2)the
vegetated area over which runoff is dispersed.
Dispersion Devices
The dispersion devices used on your property include the following as indicated on the
flow control BMP site plan: ❑ splash blocks, X rock pads, ❑ gravel filled trenches, ❑
sheet flow. The size, placement, composition, and downstream flowpaths of these
devices as depicted by the flow control BMP site plan and design details must be
maintained and may not be changed without written approval either from the City of
Renton or through a future development permit from the City of Renton.
Dispersion devices must be inspected annually and after major storm events to identify
and repair any physical defects. When native soil is exposed or erosion channels are
present, the sources of the erosion or concentrated flow need to be identified and
mitigated. Concentrated flow can be mitigated by leveling the edge of the pervious area
and/or realigning or replenishing the rocks in the dispersion device, such as in rock pads
and gravel filled trenches.
Vegetated Flowpaths
The '.vegetated area over which runoff is dispersed must be maintained in good
condition free of bare spots and obstructions that would concentrate flows.
