Prepared By: Austin O’Dell, Transit Manager
SUBJECT: AUTHORIZATION TO SUBMIT 2020-21 LOW CARBON TRANSIT

OPERATIONS PROGRAM (LCTOP) GRANT APPLICATIONS, ELECTRIC

VEHICLE (EV) INFRASTRUCTURE

RECOMMENDATION
Adopt a Resolution entitled, “A Resolution of the City Council of the City of San Luis Obispo, California, authorizing the City Manager or their Designee, to file, execute and fulfill any related Low Carbon Transportation Operations Program Grant Applications, Certifications, Assurances, Forms, Agreements, and Associated Documents on behalf of the City.”

DISCUSSION
Background Information on California’s LCTOP
The LCTOP is one of several programs that are part of the Transit, Affordable Housing, and Sustainable Communities Program established by the California Legislature in 2014 by Senate Bill 862. The California Legislature created LCTOP to provide operating and capital assistance for transit agencies to reduce greenhouse gas emissions and improve mobility, with a priority on serving disadvantaged communities. Approved projects in LCTOP support new or expanded bus or rail services, expand intermodal transit facilities, and may include equipment acquisition, fueling, maintenance, and other costs to operate those services or facilities, with each project reducing greenhouse gas emissions (GHG). Since 2015-16, Senate Bill 862 continuously appropriates five percent of the annual auction proceeds in the Greenhouse Gas Reduction Fund (Fund) for LCTOP.

The LCTOP is administered by California Department of Transportation (Caltrans) in coordination with the California Air Resource Board (ARB) and the State Controller’s Office (SCO). Caltrans is responsible for ensuring that the statutory requirements of the LCTOP are met in terms of project eligibility, greenhouse reduction, disadvantaged community benefit, and other requirements of the law.

Per Public Resource Code § 75230(f)(1)(3) funds shall be expended to provide transit operating or capital assistance that meets any of the following three criteria:

Item 5d

1. New and Expanded. Expenditures that directly enhance or expand transit service by supporting new or expanded bus or rail services, new or expanded water-borne transit, or expanded intermodal facilities, and may include equipment acquisition, fueling, and maintenance, and other costs to operate those services or facilities.

2. Increased Modality. Operational expenditures that increase transit mode share.

3. Zero-Emissions. Expenditures related to the purchase of zero-emission buses, including electric buses, and the installation of the necessary equipment and infrastructure to operate and support zero-emission buses.

Relevancy of LCTOP to the City
The City of San Luis Obispo may seek a portion of
LCTOP funds annually. Each transit operator is
entitled to funds based on a statewide formula. The
City’s currently identified allocation is $5,899; this
amount may change slightly based upon revised
State numbers.

Regionally, a discretionary amount of $285,233
available to all local transit agencies to apply for is also projected. These specific and regional LCTOP
funds require an annual grant application. This grant
application requires City Council approval. SLOCOG determines the grant awards based on one of following criteria:
 Expenditures that directly enhance or expand transit service by supporting new or expanded bus or rail services, new or expanded water-borne transit, or expanded intermodal facilities, and may include equipment acquisition, fueling, and maintenance, and other costs to operate those services or facilities.  Operational expenditures that increase transit mode share.  Expenditures related to the purchase of zero-emission buses, including electric buses, and the installation of the necessary equipment and infrastructure to operate and support zero-emission buses.

City LCTOP Grant Application for Supporting EV Infrastructure Staff is recommending that this year’s 2021-22 LCTOP grant application be made toward supporting the infrastructure costs related to the purchase and installation of electric bus charging units.

Item 5d
The State of California’s Air Resource Board has manded that transit agencies convert to zero emission vehicles by 2040. The City of San Luis Obispo’s Climate Action Plan also has the ambitious goal for City services to be carbon neutral by 2030. In support of this, City Council has previously approved the purchase of two (2) electric transit vehicles on July 7, 2020, to replace two aged diesel transit buses. These electric transit vehicles are expected to be delivered in early 2022.

These two new vehicles will therefore need to be supported with appropriate EV infrastructure and charging units. The design for this EV infrastructure and charging units is in progress. Funding to support the construction phase of this work will come from both an Air Pollution Control District and PG&E grants. Supplemental funding from LCTOP meets the intended purpose of the funds by supporting reduction in GHG emission.

Policy Context
Financial Management Manual Policy 740 requires that the City Council approve grant applications equal to or greater than $5,000. The application will request $291,132 combined with the City allocated and discretionary LCTOP funds.

Further, this project is consistent with the City’s adopted 2019 Major City Goals Financial Plan, Climate Action Plan, 2017-22 Short Range Transit Plan, the regions SLO Regional Zero Emission Bus Plan and the state’s Innovative Clean Transit Rule.

Public Engagement
This is an administrative item, so no outside public engagement was completed. Public comment can be provided to the City Council through written correspondence prior to the meeting and through public testimony at the meeting.

CONCURRENCE
This proposed project has been reviewed by the San Luis Obispo Council of Governments (SLOCOG) before submission to the City Council. SLOCOG board, Transportation Technical Advisory Committee, and Social Services Technical Advisory Committee are recommending funding for the City’s project.

ENVIRONMENTAL REVIEW
The California Environmental Quality Act does not apply to the recommended action in this report, because the action does not constitute a “Project” under CEQA Guidelines Sec. 15378.

There is no impact on the City’s General Fund as a result of applying or receiving these grant funds. Rather, securement of these funds will assist and supplement the Transit Enterprise fund in achieving its capital project goals.

ALTERNATIVES
Deny authorization request for the grant application. This is not recommended as this will leave the transit program without another funding source to pursue this vital project.

SUBJECT: REQUEST TO REMOVE THE PROPERTY AT 540 BUCHON STREET FROM THE CONTRIBUTING PROPERTIES LIST OF THE CITY’S

INVENTORY OF HISTORIC RESOURCES

RECOMMENDATION
As recommended by the Cultural Heritage Committee, adopt a resolution entitled “A Resolution of the City Council of the City of San Luis Obispo, California, removing the property at 540 Buchon Street from the Inventory of Historic Resources (HIST-0727- 2021).”

DISCUSSION
The owner of the property at 540 Buchon
Street has requested that the property be
removed from the City’s Inventory of Historic
Resources, as provided in Listing
Procedures for Historic Resources, set out in
Section 14.01.060 (C) of the City’ s Historic
Preservation Ordinance. An evaluation of
the property and its eligibility for historic
listing has been prepared by James Papp,
PhD (Historicities LLC) to inform
consideration of this request (see
Attachment B).

Site and Setting
The property is a residential parcel on the north side of Buchon Street, about 100 feet east of Beach Street, within the Old Town Historic District, one of the City’s oldest residential neighborhoods, built up historically around the turn of the 20th Century, with older structures dating back to the 1880s.

Figure 1: 540 Buchon Street

Item 5f
The site is developed with a single-family dwelling and detached garage (see Figure 1).

As described in the applicant’s Historic Resource Evaluation (Attachment B), a dwelling is depicted on the site in a 1891 Sanborn Map, the first to include this block of Buchon, and subsequent maps show a rear stable structure in 1905, later replaced by a shed and garage with composition roof by 1926 (Papp, pg. 5 & 9). Evidence suggests that the residence likely embodied a Gothic Revival style (Papp pg. 8), however the dwelling does not currently retain the characteristic form or features of the style. It was extensively remodeled in 1957, with the front section of the building having apparently been demolished and replaced (Papp, pg. 10).

Historic Listing
Historic preservation policies are set out in the Conservation and Open Space Element (COSE) of the City’s General Plan and the Historic Preservation Ordinance (SLOMC Ch. 14.01) implements these policies.

Property may be designated as a Contributing List resource where a building on it maintains its historic and architectural character, and contributes, by itself or in conjunction with other structures, to the unique or historic character of a neighborhood, district, or to the City as a whole, and satisfies at least one of the historic significance criteria listed in § 14.01.070. The subject property first appears as a “Contributing Property” in the listing of properties attached (as “Exhibit C”) to Resolution 6424 adopted in April 1988, establishing a comprehensive listing of historic properties within the City.

EVALUATION
Criteria for Historic Resource Listing
The applicant’s Historic Resource Evaluation evaluates the property against the Criteria for Historic Resource Listing provided in § 14.01.070 of the City’s Historic Preservation Ordinance, and concludes that the property is not eligible for historical listing in the City’s Inventory of Historic Resources, as the primary dwelling on the property has, since its 1957 alteration, lacked the integrity to communicate its original architectural character and the remodeled and refinished building did not later attain its own historical significance (Papp, pg. 1). In addition, the evaluation did not result in identification of any association with important historical persons or events which would otherwise make the property eligible for listing.

In order to be eligible for designation, a resource must exhibit a high level of historic integrity and satisfy at least one of the evaluation criteria listed in § 14.01.070 of the City’s Historic Preservation Ordinance. The Ordinance also provides that, while it is the general intent that property not be removed from historic listing, property may be removed if the structure on it is found to no longer meet eligibility (historic significance) criteria for listing (§ 14.01.060 (C)).

Item 5f
Architectural Criteria (§ 14.01.070 (A)). The residence on this property does not exhibit the form or characteristic features of the original dwelling constructed on the site, having been lost through extensive modifications in 1957, leaving any remaining portions without “anything to relate to” (Papp, pg. 10). Its architect is not known, though the present building as modified would no longer faithfully reflect the architect’s work.

Historic Criteria (§ 14.01.070 (B)). The Evaluation notes that the property is not associated with persons or events of historical significance that would qualify the property for historical designation (Papp pg. 10). There is no evidence that the property was associated with any famous or “first-of-its-kind” event and its construction is not considered to be a notably important, unique, or distinctly interesting contribution to the City. The home could be associated with the earliest residential development of the City, but no longer possesses the integrity to communicate this association.

Integrity. The applicant’s Evaluation describes the major modifications to the dwelling in 1957, including demolition and replacement of the front portion the building in 1957 which have resulted in the loss of the building’s original architectural character and materials, such that it would be unrecognizable in comparison with its pre-1957 form (Papp, pg. 10) Previous Council or Advisory Body Action
The Cultural Heritage Committee reviewed this Historical Preservation application (HIST0727-2021), requesting removal of the property from the City’s Inventory of Historic Resources, at a public hearing on January 24, 2022 and by a vote of 5-0 (with one Committee Member absent and one Vacancy) recommended that the Council remove the property from the Contributing Properties List, finding that the original dwelling has lost integrity due to previous alterations to the property, such that it is no longer eligible for listing as a Contributing List Resource.

Policy Context
The recommended action on this item is supported by historical preservation policies in section 3.0 of the Conservation and Open Space Element of the City’ s General Plan, and with procedures and standards for listing of historic resources of The City’ s Historic Preservation Ordinance SLOMC Sections 14.01.060 & 14.01.070. The Historic Preservation Ordinance states that in order to qualify as a resource, a high degree of integrity must be maintained and that at least one of the historic significance criteria is satisfied.

Public Engagement
Public notice of this hearing has been provided to owners and occupants of property near the subject site, and published in a widely circulated local newspaper, and hearing agendas for this meeting have been posted at City Hall, consistent with adopted notification procedures for development projects.

Item 5f

ENVIRONMENTAL REVIEW
Consideration of continued eligibility of this property for historic listing is exempt from the provisions of the California Environmental Quality Act (CEQA), as it is does not have the potential for causing a significant effect on the environment, and so is covered by the general rule described in CEQA Guidelines § 15061(b)(3). The determination of continued eligibility for historic listing is limited to review of whether the subject site remains eligible for historic resource listing according to the criteria set forth in the City’ s Historic Preservation Ordinance.

The removal of the property from the contributing properties’ list has no fiscal impact since the property is not currently eligible for historic preservation benefits (i.e. Mills Act) and the historic designation of the property has no bearing on City fiscal resources.

ALTERNATIVES

1. Maintain 540 Buchon Street on the City’ s Inventory of Historic Resources, based on findings that the property continues to satisfy the criteria for Historic Resource Listing of the City’s Historic Preservation Ordinance. This alternative is not recommended because the Historic Resources Evaluation prepared for this property indicates that the property is not eligible for listing as an historical resource.

2. Continue consideration of the request to a future date for additional information or discussion.

RESOLUTION NO. _____ (2022 SERIES)

A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF SAN LUIS OBISPO, CALIFORNIA, REMOVING THE PROPERTY AT 540 BUCHON STREET FROM THE INVENTORY OF HISTORIC RESOURCES (HIST0727-2021) WHEREAS, the applicant, Ashley Ludaescher, submitted on October 19, 2021 an application to remove the property located at 540 Buchon Street (“the Property”) from the Contributing Properties List of Historic Resources (HIST-0727-2021); and WHEREAS, the Cultural Heritage Committee of the City of San Luis Obispo conducted a public hearing via teleconference from the City of San Luis Obispo, California on January 24, 2022 to consider the application, and recommended that the City Council remove the Property from the Contributing Properties List of Historic Resources; and WHEREAS, the City Council of the City of San Luis Obispo conducted a public hearing in the Council Chamber of City Hall, 990 Palm Street, San Luis Obispo, California on March 15, 2022 for the purpose of considering removal of the Property from the Contributing Properties List of Historic Resources; and WHEREAS, notices of said public hearing and meeting were made at the time and in the manner required by law; and
WHEREAS, the City Council has duly considered all evidence, including the record of the Cultural Heritage Committee hearing and recommendation, testimony of the applicant and interested parties, and the evaluation and recommendations by staff presented at said hearing.

NOW, THEREFORE, BE IT RESOLVED by the Council of the City of San Luis Obispo as follows:

SECTION 1. Findings. Based upon all the evidence, the Council makes the following findings:
a) The property is not historically significant under the Integrity Criteria set out in § 14.01.070 (C) of the City’s Historic Preservation Ordinance. The primary dwelling on the property no longer has the integrity to qualify as a Contributing Historic Resource due to previous alteration.

Resolution No. _____ (2022 Series) Page 2
R _____
b) The removal of the property from the City’s Contributing Properties List of Historic Resources is consistent with the Historic Preservation Ordinance because the buildings on the property lack significance within the historical contexts addressed by the Evaluation Criteria for Historic Resource Listing set out in § 14.01.070 of the City’s Historic Preservation Ordinance. The eligibility of the property for inclusion in the City’s Inventory of Historic Resources has been evaluated by an architectural historian. As summarized in the applicant’s statement submitted with application HIST-0727-2021, that evaluation concluded that the primary structure on the property no longer has the integrity to qualify as a Contributing Historic Resource due to previous alteration, and that the property is not a candidate for inclusion on the City’s Inventory.

SECTION 2. Environmental Review. Consideration of continuing eligibility of this property for historic listing is exempt from the provisions of the California Environmental Quality Act (CEQA). The determination of continued eligibility for historic listing is limited to review of whether the subject site remains eligible for historic resource listing according to the criteria set forth in the City’s Historic Preservation Ordinance. A determination that the property is not eligible for historic listing will cause the removal of the property from the City's Inventory of Historic Resources, but will have no direct physical effect on the environment, as the determination does not approve any physical site development. As such, it is does not have the potential for causing a significant effect on the environment and is covered by the general rule described in CEQA Guidelines §15061(b)(3).

12 Zoning, or remove the property from historic listing if the structure on the property no longer meets eligibility criteria for listing, following the process for listing set forth herein.

14.01.070. Evaluation Criteria for Historic Resource Listing When determining if a property should be designated as a listed Historic or Cultural Resource, the CHC and City Council shall consider this ordinance and State Historic Preservation Office (“SHPO”) standards. In order to be eligible for designation, the resource shall exhibit a high level of historic integrity, be at least fifty (50) years old (less than 50 if it can be demonstrated that enough time has passed to understand its historical importance) and satisfy at least one of the following criteria:

A. Architectural Criteria: Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master, or possesses high artistic values. (1) Style: Describes the form of a building, such as size, structural shape and details within that form (e.g. arrangement of windows and doors, ornamentation, etc.). Building style will be evaluated as a measure of:
a. The relative purity of a traditional style;
b. Rarity of existence at any time in the locale; and/or current rarity although the structure reflects a once popular style;
c. Traditional, vernacular and/or eclectic influences that represent a particular social milieu and period of the community; and/or the uniqueness of hybrid styles and how these styles are put together.
(2) Design: Describes the architectural concept of a structure and the quality of artistic merit and craftsmanship of the individual parts. Reflects how well a particular style or combination of styles are expressed through compatibility and detailing of elements.

Also, suggests degree to which the designer (e.g., carpenter-builder) accurately interpreted and conveyed the style(s). Building design will be evaluated as a measure of:
a. Notable attractiveness with aesthetic appeal because of its artistic merit, details and craftsmanship (even if not necessarily unique);
b. An expression of interesting details and eclecticism among carpenter-builders, although the craftsmanship and artistic quality may not be superior. (3) Architect: Describes the professional (an individual or firm) directly responsible for the building design and plans of the structure. The architect will be evaluated as a reference to:

13 a. A notable architect (e.g., Wright, Morgan), including architects who made significant contributions to the state or region, or an architect whose work influenced development of the city, state or nation.
b. An architect who, in terms of craftsmanship, made significant contributions to San Luis Obispo (e.g., Abrahams who, according to local sources, designed the house at 810 Osos - Frank Avila's father's home - built between 1927 – 30).

B. Historic Criteria
(1) History – Person: Associated with the lives of persons important to local, California, or national history. Historic person will be evaluated as a measure of the degree to which a person or group was:
a. Significant to the community as a public leader (e.g., mayor, congress member, etc.) or for his or her fame and outstanding recognition - locally, regionally, or nationally.
b. Significant to the community as a public servant or person who made early, unique, or outstanding contributions to the community, important local affairs or institutions (e.g., council members, educators, medical professionals, clergymen, railroad officials).
(2) History – Event: Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. Historic event will be evaluated as a measure of:
(i) A landmark, famous, or first-of-its-kind event for the city - regardless of whether the impact of the event spread beyond the city.
(ii) A relatively unique, important or interesting contribution to the city (e.g., the Ah Louis Store as the center for Chinese-American cultural activities in early San Luis Obispo history).
(3) History-Context: Associated with and also a prime illustration of predominant patterns of political, social, economic, cultural, medical, educational, governmental, military, industrial, or religious history. Historic context will be evaluated as a measure of the degree to which it reflects:
a. Early, first, or major patterns of local history, regardless of whether the historic effects go beyond the city level, that are intimately connected with the building (e.g., County Museum).
b. Secondary patterns of local history, but closely associated with the building (e.g., Park Hotel).

14 C. Integrity: Authenticity of an historical resource’s physical identity evidenced by the survival of characteristics that existed during the resource’s period of significance. Integrity will be evaluated by a measure of:
(1) Whether or not a structure occupies its original site and/or whether or not the original foundation has been changed, if known.
(2) The degree to which the structure has maintained enough of its historic character or appearance to be recognizable as an historic resource and to convey the reason(s) for its significance.
(3) The degree to which the resource has retained its design, setting, materials, workmanship, feeling and association.

14.01.080 Historic District Designation, Purpose and Application A. Historic (H) District designation. All properties within historic districts shall be designated by an “H” zoning. Properties zoned “H” shall be subject to the provisions and standards as provided in Ordinance 17.54 (Zoning) of the Municipal Code.

B. Purposes of Historic Districts. The purposes of historic districts and H zone designation are to:
(1) Implement cultural resource preservation policies of the General Plan, the preservation provisions of adopted area plans, the Historic Preservation and Archaeological Resource Preservation Program Guidelines, and (2) Identify and preserve definable, unified geographical entities that possess a significant concentration, linkage, or continuity of sites, buildings, structures, or objects united historically or aesthetically by plan or physical development; (3) Implement historic preservation provisions of adopted area and neighborhood improvement plans;
(4) Enhance and preserve the setting of historic resources so that surrounding land uses and structures do not detract from the historic or architectural integrity of designated historic resources and districts; and
(5) Promote the public understanding and appreciation of historic resources.

C. Eligibility for incentives. Properties zoned as Historic Preservation (H) shall be eligible for preservation incentive and benefit programs as established herein, in the Guidelines and other local, state and federal programs.

SUBJECT: AUTHORIZATION TO ADVERTISE VERDE/LUNETA/RAMONA/BROAD SEWER PIPE REPLACEMENT, SPECIFICATION NO. 1000091

RECOMMENDATION

1. Approve the project plans and specifications for Verde/Luneta/Ramona/Broad Sewer Pipe Replacement, Specification Number 1000091; and

2. Authorize staff to advertise for bids; and

3. Authorize the City Manager, or their designee to award the Construction Contract pursuant to Section 3.24.190 of the Municipal Code for the bid total, if the lowest responsible bid is within the publicly disclosed funding amount of $1,156,000; and

4. Authorize the City Engineer to approve Contract Change Orders up to the available project budget.

DISCUSSION
Background
Replacement and rehabilitation of wastewater collection (sewer) pipes is part of an ongoing program to maintain aging and deteriorating infrastructure. This program has several objectives: 1) ensure reliable removal of wastewater; 2) reduce the need for emergency repairs; 3) reduce the need for preventive maintenance; and 4) ensure uninterrupted wastewater flow without health or environmental hazard from wastewater leakage. This project will accomplish these objectives for part of the City’s wastewater collection system.

The Project
The Verde/Luneta/Ramona/Broad Sewer Pipe Replacement Project (Project) proposes replacement of approximately 2,347 lineal feet of sewer main on Verde, Luneta, Ramona and Broad (Attachment C). The existing sewer pipes planned for replacement work have been video inspected and confirmed to have reached the end of their useful life.

Item 5g
This Project also includes an additive alternate bid item. This Project’s additive alternate bid items include four lateral connections and abandonment of 500 lineal feet of sewer main. With the additive alternate bid items, the contractors bidding the project provide the cost of the additive items of work and staff will make the determination whether to award this portion of the work if the cost is within available budget. If it is not within the available budget to award the additive alternative, the work to abandon 500 lineal feet of sewer main will have to be deferred and the existing sewer main will have to remain active.

Previous Council or Advisory Body Action
This Project was identified in the 2019-21 and 2021-23 Financial Plans that were approved by Council.

Policy Context
The City Council approved the Wastewater Collection System Infrastructure Renewal Strategy in January 2016. The plan identified a strategy for prioritizing pipeline replacement in the wastewater collection system to serve existing customers and future development in the City.

Additionally, consistent with the October 2018 Purchasing Policy Update to the July 2015 Financial Management Manual, Council approval must be obtained before proceeding with this project, as approval is required for Public Projects that cost over $175,000.

Public Engagement
Public engagement was conducted during the initial identification of this Project to be included in the 2019-21 and 2021-23 Financial Plans.

CONCURRENCE
This project has the concurrence of the Utilities Department.

ENVIRONMENTAL REVIEW
A portion of the Project is located within a potentially archeologically sensitive zone of influence (within 200 feet of Old Garden Creek). Mitigation measures approved through Mitigated Negative Declaration ER10-07 are included in the Project’s specifications and will be followed by the City’s contractor, as applicable, consistent with the requirements of the California Environmental Quality Act (CEQA).

NOTES:

1. BEFORE INSTALLATION OF THE PIPE LINER, THE HOST PIPE MUST BE CLEANED AND ALL ROCKS AND DEBRIS REMOVED.

2. SLIP LINER PIPE GRADE MUST BE MAINTAINED PARALLEL TO THE GRADE OF THE HOST PIPE. THE LINER PIPE MUST BE HELD AT THE INVERT OF THE HOST PIPE AND BE BRACED TO PREVENTFLOTATION OR MOTION DURING GROUTING.

3. A CONCRETE BULKHEAD MUST BE INSTALLED AT EACH OPEN END BETWEEN THE HOST PIPE AND

NEW PIPE TO PREVENT GROUT FROM FLOWING FROM THE ENDS WHILE FILLING THE ANNULAR SPACE BETWEEN THE TWO PIPE.

3. GROUT MIX FOR ANNULAR SPACE MUST CONSIST OF LOW DENSITY FOAM, CONCRETE COMPOSED OF WATER, CEMENTITIOUS MATERIAL AND OPTIONAL CHEMICAL ADMIXTURES. GROUT MUST HAVE A DENSITY OF 40-80 POUNDS PER CUBIC FOOT AND STRENGTH OF 300 PSI.

4. THE ANNULAR VOID MUST BE GROUTED SOLID BY INJECTING GROUT FROM ONE END OF THE PIPE RUN AND ALLOWING IT TO FLOW TOWARD THE OTHER END. VENTING OF THE ANNULAR VOID MUSTBE PERFORMED TO ASSURE UNIFORM FILLING OF THE VOID SPACE DURING THE GROUTINGPROCESS. PRESSURE ON THE ANNULAR VOID MUST NOT EXCEED 2 PSI TO AVOID DAMAGE TO THELINER PIPE. (E) 10" VCP SEWER
