3 FY Capital Improvement Program Sewer Master Plan Sewer Master Plan FY 218 FY 219 FY 22 FY 221 FY 222 FY 223 Unfunded 6, 2,9, 6, 2,9, 3,5, 6, 2,9, Damaged Sewer Pipe DESCRIPTION: This project provides for a sewer master plan for the City which will present the following information for the management of the sewer system: evaluation of the capacity of the existing sewer system, including identification of existing system deficiencies and recommendations for system improvements; and evaluation of future sewer requirements for both the short term (1 years) and long term (3 years), including identification of future deficiencies and recommendations for future system improvements based on projected population changes and land use development. This project also provides for the systematic inspection and evaluation of the City s sewer collection system through the Sewer Inspection and Evaluation Program, a five-year plan to televise the below ground sewer main pipes throughout the entire City. Although cleaned and maintained on a regular basis, the system is aged and suffers from a variety of defects which can only be determined by a Closed Caption Television (CCTV) inspection of the inside of the pipes. JUSTIFICATION: The City s existing Sewer Master Plan was last updated in 27. The focus of the 27 master plan effort was to evaluate the capability of the City's existing sewer collection and pumping system to provide service through a planning period that extends to the year 22. This data is currently used by City staff to determine peak flows in the sewer system, and to establish system deficiencies in relation to proposed developments, along with other uses. The population growth, land use, and water use which was projected in 27 is out of date and most likely, significant deviations have occurred from those projections. A new analysis is needed to identify system deficiencies and prevent future deficiencies. CCTV inspection of pipes can identify offset joints, root intrusions, and depressed pipe sections which can cause deposition of solids, reduction in the hydraulic efficiency of the pipe, and inhibit the normal maintenance procedures. SCHEDULE: The citywide sewer assessment will be completed in FY 219. RELATIONSHIP TO GENERAL PLAN: The proposed project is consistent with Land Use Element Policy 1.7 (Coordination of Capital Facilities, Infrastructure, Land Use, and Economic Development) by ensuring that the development of capital facilities and infrastructure is closely coordinated with growth to ensure high levels of service to existing and new development. IMPACT ON THE NORTHWEST: A portion of this project is located in Northwest Pasadena which is an area that has been targeted for revitalization. HISTORY: This project was created and initially funded in FY Responsible Department:

5 FY Capital Improvement Program Annual Storm Drain System Repair & Improvements Annual Storm Drain System Repair & Improvements FY 218 FY 219 FY 22 FY 221 FY 222 FY 223 1,75, 35, 35, 35, 35, 35, 1,75, 35, 35, 35, 35, 35, Damaged Storm Drain DESCRIPTION: This project provides for the repair of damaged storm drain structures and minor improvements of storm drain facilities at various locations throughout the City on an ongoing basis. JUSTIFICATION: The existing structures are an integral part of the City s storm drain system. Many of the pipes are in various stages of deterioration depending on their slope, age and the type of soil surrounding them. The City owns approximately 34 miles of storm drain (including 6,456 linear feet of corrugated metal pipe installed from 1925 to 1953); over 14 catch basins; and hundreds of culverts. Many of these elements are aged and require maintenance. Existing damaged, substandard or missing structures result in inefficient operation and create risk-prone facilities. SCHEDULE: In FY 219, repair or rehabilitation of storm drains will be completed as identified by yearly storm drain inspection and evaluation. RELATIONSHIP TO GENERAL PLAN: This project is consistent with the Public Facilities Element of the General Plan in that the City is almost fully built and the drainage system elements, particularly older facilities, are subject to ongoing repair, replacement or modification. IMPACT ON THE NORTHWEST: A portion of this project is located in Northwest Pasadena, which is an area that has been targeted for revitalization.

6 FY Capital Improvement Program NPDES Arroyo Seco Bacteria Load Reduction - Concept Study NPDES Arroyo Seco Bacteria Load Reduction - Concept Study FY 218 FY 219 FY 22 FY 221 FY 222 FY , 15, 15, 15, Arroyo Seco Outfall DESCRIPTION: This project provides for testing to determine bacterial levels throughout the watershed by identifying a source and conducting a concept study to determine a solution. JUSTIFICATION: The National Pollutant Discharge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board requires the City to take steps necessary to reduce and/or eliminate pollution in stormwater runoff. The City is one of 18 agencies that participate in an Enhanced Watershed Management Program (EWMP) group to regionally address NPDES compliance issues in the Upper Los Angeles River. The Maximum Daily Load (TMDL) is a number that represents the assimilative capacity of a receiving water to absorb a pollutant. A Load Reduction Strategy (LRS) allows the EWMP to focus on priority outfalls in the Arroyo Seco tributary to address TMDL compliance. One such outfall (AS- 41) that discharges to the Arroyo Seco contains a high E. coli level. The LRS requires that the bacteria source be removed, or the discharge diverted away from the Upper LA River system. The watershed area is approximately 697 acres, of which 99% is in the City of Pasadena. The City must implement a structural solution by September 22. SCHEDULE: A concept study will be completed in FY 219. RELATIONSHIP TO GENERAL PLAN: This project is consistent with water-related policies in the Open Space and Conservation Element by enhancing storm water quality by preventing pollution and/or trash from entering Los Angeles and San Gabriel Rivers and ocean. HISTORY: This project was created and fully funded in FY Responsible Department:

7 FY Capital Improvement Program NPDES Rio Hondo Bacteria Load Reduction - Design Phase NPDES Rio Hondo Bacteria Load Reduction - Design Phase FY 218 FY 219 FY 22 FY 221 FY 222 FY 223 6, 6, 6, 6, Los Angeles River Watershed DESCRIPTION: This project provides for the design and construction of structural diversions, as well as continued implementation of minimum control measures (MCMs) including street sweeping and collecting information via the Citizen Service Center app on water wasting and enforcing drought control measures. JUSTIFICATION: The National Pollutant Discharge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board requires the City to take steps necessary to reduce and/or eliminate pollution in stormwater runoff. The City is one of 18 agencies that participate in an Enhanced Watershed Management Program (EWMP) group to regionally address NPDES compliance issues in the Upper Los Angeles River. The Maximum Daily Load (TMDL) is a number that represents the assimilative capacity of a receiving water to absorb a pollutant. A Load Reduction Strategy (LRS) allows the EWMP to focus on priority outfalls in the Rio Hondo tributary to address TMDL compliance. Of the 11 agencies that contribute to the Rio Hondo watershed area, Los Angeles County led an effort to provide a regional solution rather than addressing multiple priority outfalls. The Regional Board accepted a proposal to address Rio Hondo TMDL compliance through three structural projects and a series of MCMs to prevent additional bacterial loading. SCHEDULE: The selected consultant will begin design in FY 219. RELATIONSHIP TO GENERAL PLAN: This project is consistent with water-related policies in the Open Space & Conservation Element by enhancing storm water quality by preventing pollution and/or trash from entering Los Angeles and San Gabriel Rivers and ocean and by increasing the efficiency of water use among Pasadena residents, and commercial and industrial organizations. SPECIAL CONSIDERATION: This project will be managed by LA County and represents Pasadena's portion of the total project cost. HISTORY: This project was created and fully funded in FY Responsible Department:

8 FY Capital Improvement Program NPDES Catch Basin Retrofit - Phase NPDES Catch Basin Retrofit - Phase 4 FY 218 FY 219 FY 22 FY 221 FY 222 FY 223 6, 6, 6, 6, Catch Basin Insert DESCRIPTION: This project provides for retrofitting of approximately 4 of the 1,4 storm drain catch basins throughout the city with connector pipe screens (CPS). JUSTIFICATION: Approximately 4 City-owned catch basins remain to be retrofitted. Regular maintenance of catch basins prevents localized flooding and assists the City with National Pollutant Discharge Elimination System (NPDES) requirements by keeping trash out of the storm drain system. The CPS prevents trash and debris from entering the storm drain system during dry weather and moderate storm flows by keeping the trash and debris inside the catch basin. NPDES requirements dictate the City retrofit catch basins that are not in sump conditions. SCHEDULE: In FY 219, Phase 4 will consist of the design and construction of the final City-owned catch basin connector pipe screen systems. RELATIONSHIP TO GENERAL PLAN: This project is consistent with water-related policies in the Open Space & Conservation Element by enhancing storm water quality by preventing pollution and/or trash from entering Los Angeles and San Gabriel Rivers and ocean. IMPACT ON THE NORTHWEST: A portion of this project is located in Northwest Pasadena, which is an area that has been targeted for revitalization. HISTORY: This project was created and fully funded in FY 219. The three previous phases that retrofited approximately 8 catch basins were completed in 29, 212, and 217, and funded under project NPDES Storm Water Pollution Prevention Program. 7.6 Responsible Department:
