4. The cost and expense of the Maintenance of the Stormwater Facilities shall be
paid by the Parties. The Parties' share of Stormwater Facilities Maintenance
costs is proportional to number of lots/parcels that Owners and Developer own
as a fraction of the total number of lots/parcels in the Property using and
benefiting from the Stormwater Facilities but excluding common ownership
lots/parcels.
5. In the event the Property is subdivided in future, the owners, heirs, assigns, and
successors in interest of each such newly created parcel(s) shall be included in
the existing HOA and be liable under this Agreement and with the HOA for their
then pro rata share of expenses reflecting such newly created parcels.
6. The Maintenance to be performed under this Agreement shall include upkeep,
repair, and improvements to adequately ensure the Stormwater Facilities are in

as the restoration of the Stormwater Facilities following any non-permitted
modification. The restoration shall be as required to restore the Stormwater
Facilities to the condition existing prior to damage or alteration.
7. Developer, Owners, and HOA are collectively responsible to the City for
Maintenance of Stormwater Facilities so long as either Developer or Owners own
any lots/parcels. Developer remains responsible for Maintenance of Stormwater
Facilities until such Facilities have been approved by the City, even if Developer
no longer owns any lots/parcels of the Property.
8. Upon establishment of an HOA and a management company to manage the
maintenance of the stormwater facilities, the Developer must notify the City of
the contact information for the HOA and management company within thirty (30)
days. At a minimum, contact information for HOA and management company

BMP MAINTENANCE FACT SHEET
FOR
STRUCTURAL BMP INF-2 BIORETENTION
Bioretention (bioretention without underdrain) facilities are vegetated surface water systems that filter water
through vegetation and soil, or engineered media prior to infiltrating into native soils. Bioretention facilities are
designed to infiltrate the full design capture volume (DCV) into native soils. They have no underdrain, and no
impermeable liner.Typical bioretention components include:
• Inflow distribution mechanisms(e.g., perimeter flow spreader or filter strips)
• Energy dissipation mechanism for concentrated inflows(e.g.,splash blocks or riprap)
• Shallow surface ponding for captured flows
• Side slope and basin bottom vegetation selected based on climate and ponding depth
• Non-floating mulch layer
• Media layer(planting mix or engineered media)capable of supporting vegetation growth
• Filter course layer consisting of aggregate to prevent the migration of fines into uncompacted native soils
or the optional aggregate storage layer
• Optional aggregate storage layer for additional infiltration storage
• Uncompacted native soils at the bottom of the facility
• Overflow structure
Normal Expected Maintenance
Bioretention requires routine maintenance to: remove accumulated materials such as sediment, trash or debris;
maintain vegetation health; maintain infiltration capacity of the media layer; replenish mulch; and maintain
integrity of side slopes, inlets, energy dissipators, and outlets. A summary table of standard inspection and
maintenance indicators is provided within this Fact Sheet.
Non-Standard Maintenance or BMP Failure
If any of the following scenarios are observed, the BMP is not performing as intended to protect downstream
waterways from pollution and/or erosion. Corrective maintenance, increased inspection and maintenance, BMP
replacement,or a different BMP type will be required.
• The BMP is not drained between storm events. Surface ponding longer than approximately 24 hours
following a storm event may be detrimental to vegetation health, and surface ponding longer than
approximately 96 hours following a storm event poses a risk of vector(mosquito) breeding. Poor drainage
can result from clogging of the media layer, filter course, aggregate storage layer, underlying native soils,
or outlet structure. The specific cause of the drainage issue must be determined and corrected. If it is
determined that the underlying native soils have been compacted or do not have the infiltration capacity
expected,the[City Engineer] shall be contacted prior to any additional repairs or reconstruction.
• Sediment, trash, or debris accumulation greater than 25°% of the surface ponding volume within one
month. This means the load from the tributary drainage area is too high, reducing BMP function or
clogging the BMP. This would require pretreatment measures within the tributary area draining to the
BMP to intercept the materials. Pretreatment components, especially for sediment,will extend the life of
components that are more expensive to replace such as media,filter course,and aggregate layers.
INF-2 Page 1 of 11
January 12, 2017
INF-2
Bioretention
• Erosion due to concentrated storm water runoff flow that is not readily corrected by adding erosion
control blankets, adding stone at flow entry points, or minor re-grading to restore proper drainage
according to the original plan. If the issue is not corrected by restoring the BMP to the original plan and
grade,the[City Engineer]shall be contacted prior to any additional repairs or reconstruction.
Other Special Considerations
Bioretention is a vegetated structural BMP. Vegetated structural BMPS that are constructed in the vicinity of, or
connected to, an existing jurisdictional water or wetland could inadvertently result in creation of expanded waters
or wetlands. As such, vegetated structural BMPs have the potential to come under the jurisdiction of the United
States Army Corps of Engineers, SDRWQCB, California Department of Fish and Wildlife, or the United States Fish
and Wildlife Service. This could result in the need for specific resource agency permits and costly mitigation to
perform maintenance of the structural BMP. Along with proper placement of a structural BMP, routine
maintenance is key to preventing this scenario.

SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR INF-2 BIORETENTION
The Property owner Is responsible to ensure Inspection,operation and maintenance of permanent BMPs on their property unless responsi luImy has been formally transferred
to an agency,comm u city facilities district,homeowners association,property owners association,or other special district.
Maintenance frequencies listed in this table are average/typical frequencies.Actual ma l mma nce needs are site-specific,antl maintenance may be requ lred more frequently.
Me lnteni nce must be performed whenever needed,based on maintenance indicators presented in this table.The BM owner is responsible for conducting regular inspections
to see when maintenance is needed based on the maintenance Indicators.During the first year of operation of a structural BMP,inspection Is recommended at least once prior
to August 31 and then monthly from September through May Inspection during a storm event is also recommended After the initial period of frequent Inspections,the
minimum Inspection and maintenance frequency can be determined based on the results of the first year inspections.
Threshold/Indicator Maintenance Anion Typical Maintenance Frequency

Permeable Pavement as Site Design BMP
BMP MAINTENANCE FACT SHEET
FOR
SITE DESIGN BMP SD-6B PERMEABLE PAVEMENT AS SITE DESIGN BMP
Permeable pavement is pavement that allows for percolation through void spaces in the pavement surface into
subsurface layers.When used as a site design BMP,the subsurface layers are designed to provide storage of storm
water runoff so that outflow rates can be controlled via infiltration into subgrade soils. As a site design BMP,
permeable pavement areas are designed to be self-retaining and are designed primarily for direct rainfall. Self-
retaining permeable pavement areas have a ratio of total drainage area(including permeable pavement)to area of
permeable pavement of 1.5:1 or less. Permeable pavement as structural BMP usually receives runoff from a larger
tributary area than permeable pavement as site design BMP (see INF-3 for permeable pavement as structural
BMP). Permeable pavement surfaces can be constructed from modular paver units or paver blocks, pervious
concrete, porous asphalt, and turf pavers.Typical components include:
• Permeable surface layer
• Bedding layer for permeable surface
• Aggregate storage layer with optional underdrain(s)
• Optional final filter course layer over uncompacted existing subgrade
• Optional subsurface check dams at regular intervals when pavement is sloped (more closely spaced on
steeper slopes)
Normal Expected Maintenance
Routine maintenance of permeable pavement includes: removal of materials such as trash and debris accumulated
on the paving surface; vacuuming of the paving surface to prevent clogging; and flushing paving and subsurface
gravel to remove fine sediment. If the BMP includes underdrains,check and clear underdrains.A summary table of
standard inspection and maintenance indicators is provided within this Fact Sheet.
Non-Standard Maintenance or BMP Failure
If the permeable pavement area is not drained between storm events, or if runoff sheet flows across the
permeable pavement area and flows off the permeable pavement area during storm events, the BMP is not
performing as intended to protect downstream waterways from pollution and/or erosion. During storm events up
to the 85`h percentile storm event (approximately 0.5 to 1 inch of rainfall in San Diego County), runoff should not
flow off the permeable pavement area. The permeable pavement area is expected to have adequate hydraulic
conductivity and storage such that rainfall landing on the permeable pavement and runoff from the surrounding
drainage area will go directly into the pavement without ponding or overflow (in properly designed systems, the
surrounding drainage area is not more than half as large as the permeable pavement area). Following the storm
event,there should be no standing water(puddles)on the permeable pavement area.
If storm water is flowing off the permeable pavement during a storm event, or if there is standing water on the
permeable pavement surface following a storm event, this is an indicator of clogging somewhere within the
system. Poor drainage can result from clogging of the permeable surface layer, any of the subsurface components,
or the subgrade soils. The specific cause of the drainage issue must be determined and corrected. Surface or
subsurface ponding longer than approximately 96 hours following a storm event poses a risk of vector(mosquito)
breeding. Corrective maintenance, increased inspection and maintenance, BMP replacement, or a different BMP
type will be required. If poor drainage persists after flushing of the paving, subsurface gravel, and/or underdrain(s)
when applicable,or if it is determined that the underlying soils do not have the infiltration capacity expected, the
[City Engineer]shall be contacted prior to any additional repairs or reconstruction.

SD-6B
Permeable Pavement as Site Design BMP
Other Special Considerations
Site design BMPs, such as permeable pavement, installed within a new development or redevelopment project are
components of an overall storm water management strategy for the project. The presence of site design BMPs
within a project is usually a factor in the determination of the amount of runoff to be managed with structural
BMPs (i.e., the amount of runoff expected to reach downstream retention or biofiltration basins that process
storm water runoff from the project as a whole). When site design BMPs are not maintained or are removed, this
can lead to clogging or failure of downstream structural BMPs due to greater delivery of runoff and pollutants than
intended for the structural BMP. Therefore, the [City Engineer] may require confirmation of maintenance of site
design BMPs as part of their structural BMP maintenance documentation requirements. Site design BMPs that
have been installed as part of the project should not be removed, nor should they be bypassed by re-routing roof
drains or re-grading surfaces within the project. If changes are necessary, consult the [City Engineer] to determine
requirements.
The runoff storage and infiltration surface area in this BMP are not readily accessible because they are subsurface.
This means that clogging and poor drainage are not easily corrected. If the tributary area draining to the BMP
includes unpaved areas, the sediment load from the tributary drainage area can be too high, reducing BMP
function or clogging the BMP. All unpaved areas within the tributary drainage area should be stabilized with
vegetation. Other pretreatment components to prevent transport of sediment to the paving surface,such as grass
buffer strips, will extend the life of the subsurface components and infiltration surface. Along with proper
stabilization measures and pretreatment within the tributary area, routine maintenance, including preventive
vacuum/regenerative air street sweeping,is key to preventing clogging.

SUMMARY OF STANDARD INSPECTION AND MAINTENANCE FOR SD-6B
PERMEABLE PAVEMENT AS SITE DESIGN BMP
The property owner is responsible to ensure Inspection,operation and maintenance of permanent BMPS on their property unless responsibility has been formally transferred to
an agency,community facilities district,homeowners association,property owners association,or other special district.
Maintenance frequencies listed in this table are average/typical frequencies.Actual maintenance needs are site specific,and maintenance may be required more frequently.
Maintenance must be performed whenever needed,based on maintenance Indicators presented In this table.The BMP owner Is responsible for conducting regular inspections
to see when maintenance is needed based on the maintenance Indicators.During the first year of operation of a structural BMP,Inspection Is recommended at least once prior
to August 31 and then monthly from September through May. Inspection during a storm event is also recommended.After the Initial period of frequent Inspections,the
minimum inspection and maintenance frequency can be determined based on the results of the first year Inspections.
