First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
A Preliminary Project-Specific WQMP may be required When a project is subject to discretionary approval during the
planning and entitlement process (tentative tract map parcel map or subdivision map) and
Will be subject to ministerial approvals for subsequent grading or building permits
Submit WQMP with project application
PreliminaryWater Quality Management Plan
During Entitlement
38
PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

56
DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
A Preliminary Project-Specific WQMP may be required When a project is subject to discretionary approval during the
planning and entitlement process (tentative tract map parcel map or subdivision map) and
Will be subject to ministerial approvals for subsequent grading or building permits
Submit WQMP with project application

38
PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

56
DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category
58

60
Letrsquos Walk ThruThe Checklist
Sample Checklist - DAMP Figure 6-2b The bottom area tells
you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use
P=A Potential Pollutant N=Not a Potential Pollutant

Project Pollutants SedimentTurbidity - A potential pollutant (Note 1) Nutrients ndash A potential pollutant (Note 1) Organic Compounds ndash A potential pollutant (Note 5) Trash and Debris ndash A potential pollutant Oxygen Demanding Substances ndash A potential pollutant (Note 1) Bacteria and Viruses ndash A potential pollutant (Note 3) Oil and Grease ndash A potential pollutant Pesticides ndash A potential pollutant (Note 1) Metals ndash A potential pollutant
Note 1 ndash A potential pollutant if landscaping or open area exists on the project site
Note 3 ndash A potential pollutant if land use involves animal waste Note 5 ndash Specifically solvents
66
DeterminingProject Pollutants
Project Pollutants Stick with Exhibit B unless you have a very good reason to
deviate If you deviate document your reasons in the project filehellipyou

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

56
DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category
58

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use

68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

56
DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use
P=A Potential Pollutant N=Not a Potential Pollutant

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use

68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
A Preliminary Project-Specific WQMP may be required When a project is subject to discretionary approval during the
planning and entitlement process (tentative tract map parcel map or subdivision map) and
Will be subject to ministerial approvals for subsequent grading or building permits
Submit WQMP with project application

38
PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

56
DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use
P=A Potential Pollutant N=Not a Potential Pollutant

Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

60
Letrsquos Walk ThruThe Checklist
Sample Checklist - DAMP Figure 6-2b The bottom area tells
you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use
P=A Potential Pollutant N=Not a Potential Pollutant

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category

69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
A Preliminary Project-Specific WQMP may be required When a project is subject to discretionary approval during the
planning and entitlement process (tentative tract map parcel map or subdivision map) and
Will be subject to ministerial approvals for subsequent grading or building permits
Submit WQMP with project application

38
PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category
58

60
Letrsquos Walk ThruThe Checklist
Sample Checklist - DAMP Figure 6-2b The bottom area tells
you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category
WQMP Exhibit B identifies expected pollutants for each project category
63
DeterminingProject Pollutants
Exhibit B is easy to use Exhibit B is easy to use
P=A Potential Pollutant N=Not a Potential Pollutant

Note 1 ndash A potential pollutant if landscaping or open area exists on the project site
Note 3 ndash A potential pollutant if land use involves animal waste Note 5 ndash Specifically solvents
66
DeterminingProject Pollutants

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site
IdentifyingReceiving Water Impairments

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57

Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

you whether a WQMP is required
61
DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62
DeterminingProject Pollutants
Expected Project Pollutants depend on the Project Category

Identifying theProject Watershed and Sub-Watershed
Identify the project watershedhellip Santa Margarita River Watershed
On-line tool available at httprcfloodorgNPDES
68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57

Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific
enough to identify the land required for BMP implementation
A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination
WQMP Guidance Document Section 3 provides a narrative description of each project category

DeterminingProject Category - Summary
The Checklist is easy to use
If a project has attributes of one or more of the Priority Development Project Categories then a WQMP is required WQMP applies to the entire
project for new development See the ldquo50 Rulerdquo to
determine where the WQMP applies for significant redevelopment
62

68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR

Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

PreliminaryProject-Specific WQMP
Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought Key point ndash The Preliminary WQMP needs to be specific

A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57

68
Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments

IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

First Things FirstWhat Is A WQMP
Water Quality Management Plan The WQMP is a project-specific plan of Best
Management Practices (BMPs) including site design source controls and treatment controls to address post-construction urban runoff quality and quantity to protect receiving waters
A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category

gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

Identifying theProject Watershed and Sub-Watershed
Identify the sub-watershedhellip The Basin Plan has a nice list
of sub-watersheds
Remember to consider adoptedBasin Plan Amendments
69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

DeterminingProject Category
A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project
57
DeterminingProject Category
Use the Checklist included in DAMP Figure 6-2b ndash SMR
Watershed Provides a place to
document category determination

69
Identifying theProject Watershed
Correct identification of the watershed and sub-watershed is critical to identification of Receiving Waters Impairments and Pollutants of Concern
Example Situation (From 2010 CWA Section 303(d) List and TMDLs) Murrieta Creek ndash Impaired due to Chlorpyrifos Copper Iron
Manganese Nitrogen Phosphorus and Toxicity Santa Margarita River (Upper) ndash Impaired due to Phosphorus
and Toxicity Santa Margarita River (Lower) ndash Impaired due to Enterococcus
Fecal Coliform Phosphorus and Total Nitrogen Example Ramifications
All three waters are in the Santa Margarita River watershed Discharges to all three waters require extra attention to
Phosphorus due to the impairments Discharges to Murrieta Creek require extra attention to
Chlorpyrifos and Metals due to impairments
70
IdentifyingProject Receiving Waters
Project watershed and sub-watershed provide for receiving water identification
Maps from Flood Control USGS and others are useful in finding the receiving waters
71
IdentifyingProject Receiving Waters
Proximate Receiving Waters ndash Generally receiving waters closest to your project A precise definition has not been established When TMDLs come into play they are likely to push the
ldquoProximate Thresholdrdquo further downstream
Downstream Receiving Waters ndash Include all receiving waters that could receive drainage from the project site

Summary of Requirements
Post-construction water pollution control a requirement for many years is now being more rigorously enforced A WQMP is required for all but the smallest of projects Final Project-Specific WQMP is required before issuance of
gradingbuilding permits Preliminary Project-Specific WQMP may be required during
project entitlement phase
Changes to the post-construction water pollution control program are forthcominghellip Until the changes are in place the program that has been in
place for the last few years must continue to be implemented

A correct Project Category determination is essential The Project Category is a key factor inhellip
Deciding whether a WQMP is required Identifying the pollutants likely to be associated with the
project
The correct Project Category is easy to determine for most projects
Projects that fall into the ldquogray areasrdquo of the category definitions will require careful consideration
An incorrect determination of Project Category could create significant future headaches such ashellip Permit enforcement actions against the agency or owner Requirements to retrofit a complete or near-complete project

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to
address hydromodification Procedures to be developed
Requires detailed analysis ldquoOff rampsrdquo may ease compliance burden for some projects

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to
address hydromodification Procedures to be developed

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to
address hydromodification Procedures to be developed

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to
address hydromodification Procedures to be developed

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to

Hydromodification
138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development
Hydromodification
139
Hydromodification Management Goal ndash Geomorphic stability in channels
Santa Margarita River Watershed Presumption ndash Priority Development Projects will need to
address hydromodification Procedures to be developed
Requires detailed analysis ldquoOff rampsrdquo may ease compliance burden for some projects

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

138
Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
Summary Hydromodification is triggered by changes in hydrologic processes associated with traditional development

Distinct definitions for each watershedhellip Hydromodification-SMR The change in the natural watershed
hydrologic processes and runoff characteristics (ie interception infiltration overland flow interflow and groundwater flow) caused by urbanization or other land use changes that result in increased stream flows and sediment transport In addition alteration of stream and river channels such as stream channelization concrete lining installation of dams and water impoundments and excessive streambank and shoreline erosion are also considered hydromodification due to their disruption of natural watershed hydrologic processes
