BACKGROUND In December 2010, the State Coastal Conservancy awarded $475,000 for planning and design of the trestle.rehabilitation. The Coastal Conservancy requires a $25,000 match that the City and SMART are meeting with in-kind services. SMART is supportive of the current work, but no formal commitments have been made regarding the future ownership or responsibility for maintenance of the trestle structure. On December 14, 2011, a public meeting was held topresenf.the.process to date, the results of the preliminary analysis of the trestle structure and three alternative approaches to rehabilitate/reconstruct the trestle. In summary, all of the attendees were in favor of restoring the trestle>in,some;fashion as opposed to its removal. Opinions differed between preference for a fullreplacernent pfoject.(Alternative 3) and the rehabilitation project that maintains as much of the existing structure as feasible(Alternative,1). On February 6, 2012, staff presented the project development to date and a summary of the public comments from the December Public Meeting to City Council. Staff received commentary from the Council that indicated a preference for Alternative 1 —Rehabilitation. Council members indicated a desire to maintain as much of the existing structure as feasible. Work since the Council meeting focused on developing Alternative 1 and the California Environmental Quality Act (CEQA) environmental document. Agenda Revie )v ^ j City Attorney 1" Finance Director City Manager On June 26, 2012, staff presented the project to the Historical and Cultural Preservation Committee (HCPC) and received,a unanimous recommendation,to Council for selecting Alternative 1 and adopting the Mitigated Negative Declaration, In addition, one committee member requested the addition of the mid-span pedestrian bridge which is•discussed in more detail as an option to Alternate 1 in attachment 2 of this report. It was recommended that staff confirm the potential impacts to fish be properly investigated. Another comment was regarding the potential impact of implementation of the mitigation that may become necessary when the brackish marsh is established at a new location.This may be necessary if existing brackish marsh is impacted during construction, and concern that the construction impacts may not have been adequately defined specifically related to land-based vs. water-based construction operations. The project consultant has been directed to consider and address these comments. DISCUSSION The "preferred" project forpurposes-of primary study in the Mitigated Negative Declaration (MND) is Alternative 1, but Alternatives 2 and 3 are also considered for informational purposes. A CEQA Initial Study and MND has been prepared and published for public comment. As the governing body, the Council is responsible for adopting the MND and designating the preferred alternative. An Environmental Impact Report (EIR) is not required because the project impacts can be mitigated. Consistent with a MND, the project,proposes to rehabilitate the existing structure to address safety issues and use it aspedestrian promenade while maintaining the tracks for possible future use. As proposed, the final form of the trestle will be the same as the structure that exists currently. The rehabilitation alternatives have estimated construction costs from $3.4 million to $4.7 million. • The Historic Resource Evaluation was completed at the outset of the current project to determine the historic resource eligibility of the downtown trestle to the National Register of Historic Places and the California Register of Historical Resources. The trestle appears to be eligible for the California Register, but not eligible for the National Register. During the public review period of June 13 to July 16, 2012, staff received comments from the Petaluma Yacht Club and the State Lands Commission. Staff responded to the Yacht Club and has attached the correspondence. The State Lands Commission comments have been incorporated into the MND. Staff recommends that Council adopt the MND and authorizes staff to direct the engineering design firm to begin the detailed design process.for Alternative 1. Alternative 1 will rehabilitate the existing structure by retaining as much of the existing material as is practical. The decking must be completely replaced, but a large portion of the stringers, and bent caps can be reused. Except for the piles all material structurally inadequate will be replace with wood materials of same or similar dimensions to maintain the look and feel of the original trestle. Due to potential impacts from pile driving of'timber piles, augured in steel piles and steel shells would likely be used to replace or strengthen existing timber piles. The steel pile will extend only to the high water line, with either existing or replacement timber piles extending beyond that elevation best • 2 • maintaining the original trestle.design. Design is scheduled,for,completion by the end of the calendar year. The State Coastal Conservancy grant requires,close-out by March 31, 2013. The proposed action meets City Council goal: "Plan for and implement priority capital projects as funding permits." FINANCIAL IMPACTS The study and design project is within the prior approved budget for work. The completion of environmental clearance process will allow staff to search for and apply to granting agencies for construction funding. The Coastal Conservancy may contribute up to another $500,000 toward the construction phase if they have funding available and find a subsequent grant application worthy. Staff is seeking grant opportunities for the future project and working to define discrete projects within the overall project that could be grant funded in advance. ATTACHMENTS 1. Resolution 2.

Staff is directed to•proceed with design and specification documentation for the Project, Alternative I, Rehabilitation. 1926051 • 6 • Attachment 2, Alternative 1 —Rehabilitation Approach The objective of Alternative 1 is to retain as much of the original structure.as possible in order to maintain the historic integrity of the trestle and provide a pedestrian amenity and connection for the downtown area, while maintaining the railroad tracks. In general, components of the existing trestle can be both repaired and retained as part of the rehabilitated structure, or for those that are too far deteriorated, replaced. The components.that remain in good condition, including piles, can be preserved. According to an evaluation of the condition of the trestle piles conducted in late 2011, approximately 70%of the piles were-.identified:as being in"fair", "poor" or "beyond poor' condition with significant section loss due to microbial decay=and dry rot. The majority of the piles cannot withstand full loads and will require treatment for strengthening or replacement. To approach the trestle rehabilitation with a consistent method both for design integrity and aesthetic value, three rehabilitation scenarios were developed foi1heg piles:=repair piles (A), replace with steel piles (B), and replacewith wood piles (C).. At the initiation of the environmental assessment, staff considered option C to,be theipreferred'method since new wood piles would provide the desired original look while installing new timber that is treated for installation within waterways to modern best-management-practices (BMP's) acceptable to environmental protection agencies. However, the impact,related to pile driving and the resulting vibration poses a risk of damage to-the adjadenthistoric downtown buildings that.may be too great for the City to mitigate. In light of this, staff considers the repair option (A) or(B)'to be the best project approach. Following is a discussion of the rehabilitation approaches for the different trestle components. Rehabilitation Scenario A: Timber piles-to be repaired with a fiberglass reinforced plastic (FRP) jacket placed over the existing,pile from approximately one foot below mud line to mean highest high water(MHHW) and filled with;grout:to provide structural integrity. If the section of the existing pile is found to be deteriorated above MFIHW, a.new'timber pile section-would be spliced using a steel sleeve with mechanical connections. The remainder of the piles will have a steel sleeve installed to provide visual consistency: Rehabilitation Scenario B: Timber piles to be repaired with an auguredisteel pipe pile extending to MHHW and new timber pile section spliced with mechanical connections to support the bent cap. The remainder of the piles will have a steel pipe sleeve installed to provide visual consistency. Rehabilitation Scenario C: Timber piles to be replaced would be reinoved.and,a new coated timber pile would be installed. Timber piles in good condition and able to be preserved must be wrapped with PVC or HDPE sheets extending to MHHW to prevent future creosote leaching into the water, retard further deterioration,and maintain visual consistency: Since timber piles must be driven, or vibrated into place, this method is not recommended due to potential impacts to adjacent buildings. Approximately forty piles (eight bents of five piles each) in:the,middle section of the trestle have shifted away from the bank possibly due to adjacent slope failure pushing the piles out of alignment. Due to the condition of these piles, the recommended solution is to replace these 1926051.1 7 piles with steel pip •piles extending to the MHHW line with;a wood`section at the,top to connect. with the bent cap and provide,a.historically accurate look. The steel pilesrunlike wood piles can be augured in to greatly reduce ground vibration. It is not possible to precisely identify which part of the trestle would be repaired and retained and those that would require replacement due to the unknown timeframe,foractual.constrnotion. The trestle is continuing to deteriorate;what may be repairable today may need to be replaced in a few years. It is expected that much of the wood'components above the piles (bent caps, stringers,joists, outriggers and ties) are in good and useable condition will be retained and reused. Sections of these wood components that have deteriorated will be replaced in-kind. The deck boards and joists are unusable and will be completely replaced. Several components of the trestle are mutually exclusive of which alternative is selected, and discussed at the public meeting. • The existing tracks will be replaced in their current alignment, for possible future use. • The hand railing is not an original component of the structure and since there was no railing during the active original use of the trestle, there is no historic material to save and no design to copy. Current building codes set certain requirenients of the railing design upon the project. At this time,.staff-is intending fcontinuationrofthe railing installed a few years ago during the Water Street Plaza project, or something similar to maintain consistency. • Some citizen comments suggested the addition of a mid-span pedestrian bridge. Historically, a spur railroad line split off the trestle, heading south, approximately between First and Second.Streets, paralleling both. The.mid-span pedestrian crossing was further investigated and, although both desirable and,feasible;from an engineering standpoint, the estimated costs,for planning and design prohibit inclusion into the project at this time. • The fender piles are a lineof solid timber piles, spaced approximately four feet apart, and approximately four feet from the trestle structure. This line of fender piles is visible from across the Turning Basin, however, they are not required for,any%structuralpurpose. It is staffs intention to include construction of removal and replacement fender piles,;possibly of the same material as whatever becomes the recommended alternative,of the,trestle, as an alternative bid in the construction documents. This will allow City Council to decide on inclusion of the fender piles, based on actual cost, at the time of contract award. • 8 r1 O.•G . N .

Staff also recommends that the Historic and Cultural Preservation Committee recommend the City Council adopt the Mitigated Negative Declaration for the project. PROJECT SUMMARY Project: Downtown Railroad Trestle Rehabilitation ProJect Project Applicant: City of Petaluma,Department of Public Works,and Utilities Property Owner: Sonoma Marin Area Rail Transit Nearest Cross Street: Water Street and Western..Street Site Characteristics: The subject property is located on the west bank:of the Petaluma River beginning at the terminus of WesternStreet running along the Water Street side fo the Great Petaluma Mill and the intersection of B and Second Streets,and ends near the Yacht Club. Zoning: Adjacent to T-5 GP Land Use: Adjacent to Mixed Use Subsequent Actions: City Council decision on MND and alternative Building Permit • 10 Page I PROJECT DESCRIPTION . • BACKGROUND The downtown trestle begins at the terminus of Western Street, runs along the Water Street side of the Great Petaluma Mill and the intersection of B and;Second Streets, and endssnear the Yacht Club. The 90-year old structure is ownedby the Sonoma Mann AreaRail Transit(SMART). In recent year it has become unsafe for pedestrian use and is fenced off. In 2002, as part of the River Enhancement Project,'a City consultant developed a"Preliminary Study of the Water Street Trestle Evaluation and Replacement:" The studygave an approximate • age, description of the trestle, evaluation of the condition and recommendation'to`prohibit pedestrian and vehicular traffic. The report also provided rehabilitation•and replacement schemes, with estimated costs. In 2007, a Historic Structure Report was completedto;:research the origins of the trestle, create a chronology of railroad ownership, and•perform preliminary•engineeruig.and rehabilitation cost estimation for both pedestrian and trolley loading. Although engineering analysis,forthe current project reached a different conclusion, ass discussed below, the"Treatment Recommendations" section in the 2007 report stated,that rehabilitation for pedestrians Only-Would retain more of the trestle's historic fabric and original construction, but that rehabilitation to iallowtr011ey use would require a majority replacement of the trestle structure. In March 2010, the City submitted a grant:application to the State Coastal Conservancy requesting, $500,000 for planning and design of the trestle.rehabilitation, including bank stabilization measures, environmental clearance and necessary permits, and an educational component, The Coastal Conservancy required a 5%financial match'that the City split with SMART'as a.project partner. Although SMART is supportive of the current work,no other commitments have+been made regarding the future ownership or;responsibility for maintenance of the trestle structure. hi December 2010, City Council accepted the grant and in spring-2011,staff issued a request for proposals that resulted in the selection of,GHD, Inc. as the consultant engineenng firm. The work to date has comprised of a historical evaluation to determine eligibility,engineering analysis to develop alternative project approaches„Secretary ofthe Interior,standard evaluation of the project alternatives and the CEQA initial study;and mitigated negative declaration. The final product for' • the work funded by this grant will be construction drawings and specifications. Staff and the consultants considered three general alternatives for the project, Altemative 1 will maintain as much of the existing structure as feasible.,.Alternative 3 is a full replacemerit,.or • � reconstruction of the trestle tcy appear similar to the originalbutwith modern materials and construction methods to provide;for a longer expected life:, Alternative 2!is a compromise between . the Alternativel and Alternative'3,:and involves constructinga new trestle support structure while maintaining or reusing existing components, and allowing1exrsting piles to remain in place,,intheir existing condition. In Alternatives 2 and 3, steel piles•were;suggested.to replace the timber-piles for structural integrity, longevity, ease of installation and future maintenance. The auger-head style steel piles would be less disturbing to the adjacent businesses due to the torque-down°methodof installation rather than impact pile.driving. Additionally, any treated wood utilizedin the river is currently required to be coated or wrapped. Untreated wood is subject to tide cycles resulting in a shorter lifespan as wood not having the opportunity to dry'completely will.tot In Alternatives 2 • 11 Page 2 and 3, the wood components above;the piles would be replaced&with'-wood or colored and textured concrete. Based on past reports it was expected that the cost of constructing the trestle for trolley loading would be significantly more expensive,than pedestrian only loading. However, after further investigation, it was determined that pedestrian only loading does;notchange the design significantly. Since the cost difference is expected to be minor(or non'existent),rather than limit future use, all alternatives were developed to be adequate for both trolley and pedestrian loading. This project will design the trestle with-a deck for public pedestrian use Any improvements to the structure needed for future trolley operation would be addressed in a subsequent project. City staff, SMART staff,and the design consultants met to discuss the alternatives. The concern with either of the rehabilitation.alternatives,(Alts. 1 or 2) is that the modifications necessary to make the trestle structurally adequate and safe for,pedestrians would require,such alterations that its appearance would be drastically and negatively impacted. The consensus opinion within this group was a replacement (Alt. 3) would,provide a far more attractive structure, which would appear more similar to the original design of the trestle, and would provide a longer'life.and minimize ongoing maintenance. r - On December 14,2011, a public meeting was.held to present the process to date, share the results of the preliminary analysis of the trestle structure, and outline theTthree alternative approaches to rehabilitate/reconstruct the trestle. All of the attendees were in favor of restoring the trestle'in some fashion as opposed to a'full reconstruction. Opinions differed between the project alternatives and the specific details. Alternative 1 was favored by some,since it maintained more of the original materials. Some were of the opinion this alternative made,the structure"ugly" by wrapping the;piles and adding structural members. Based on a citizen's,boniments,this alternative would be modified from the schematic in the presentation to uniformly treat',the piles to:create a consistent appearance. Any added structural members would be hidden as much as possible behind exiating-niaterials. Pile repair and replacement would be done selectively to maintain the"maximum of the original structure. Alternative 2 was clearly the least popular alternative since it added new'"bents,"'(the vertical components of a trestle)between the existing ones creating a completely trestle. Alternative 3 was supported, provided the new materials are made to look as much like the original wooden structure as possible. Opponents to this alternative wanted to make it clear that this alternative builds a"replica" with no authenticity, and does not maintain any of the historicatintegrity. The discussion about lossi of the original materials;led to aediscussion about possibly maintaining some components of original structure. Some suggestions were:to keep, or reconstruct one bent of the new structure out of the'original material, use some of the original material as a.facade on the exposed face of a new trestle,rebuild a bent as a monument(separate from the trestle), or use exiting materials to construct an additional pedestrian connection to the trestle (discussed below). On February 6, 2012, staff presented the project development to date and received commentary from the Council clearly preferring Alternative 1 —rehabilitation. Some Councilmembers further stated the need to maintain as much of the existing structure as feasible. Page 3 12 • • DESCRIPTION The objective of this project and the development of Alternative 1 —Rehabilitation is;to:retain as much of the original structure as possible in order to maintain the historic integrity of the trestle and provide a pedestrian amenity and connection for the,downtown'area. Imgeneral, components of the existing trestle will either be repaired and retained as part of the rehabilitated structure, or for those components that are too far deteriorated,replacement may be required. A fewtrestle piles remain in good condition and can be preserved. According to an evaluation of the condition of the trestle piles conducted in late 2011,approximately 70Wof the:piles were identified as being in'"fair" or "beyond poor"condition with significantsections loss due to microbial decay and dry rot. The majority of the piles canhot withstand fill loads and will require treatment for strengthening. All components to be repaired and retained in the rehabilitated structure in direct contact with the Petaluma River water will.be wrapped to mean high higher water,(MHHW). Components being replaced and in contact with water would be treated with a waterborne preservative,Ammonlacal Copper Zinc Arsenate (ACZA)!and.either coated with an epoxy or wrapped to prevent'chemical leaching into the Petaluma River. Untreated wood subjected to tide oyeles'not.having?the opportunity to dry completely will rot resulting in a shorter'lifespan. For those components being replaced (excluding the piles which are described in more detail wider construction methods below), the existing component would be replicated in design, color, texture, and where feasible, materials. The current Alternative 11 has,been modified to uniformly treat the piles to create a consistent appearance in response to previous concernsexpressed at the public meeting. Pile repair and replacement would be done selectively to maintain.the maximum possible of the original structure. Any added structural members would be hidden as much as possible behind existing materials. The few timber piles in good conditionand able to be preserved would be wrapped with PVC or HDPE sheets extending to MHHW to prevent:future creosote leaching into the water. The piles would be cleaned of marine growth prior to wrapping and the *rap would be secured to the piles using straps or bolts. Timber piles to be repaired would have a steel, HDPE.or FRP jacket,placed over the existing pile from approximately one foot below mudline to NIIIIIW and filled with grout to provide structural integrity. If the section of the existing.pile is found to be deteriorated<above MIHHW, a new:timber pile section would be spliced using a steel pile sleeve with mechanical,connections. The new timber pile sections would be treated with a waterborne preservative. Timber piles to be replaced would be cut at the mudline: If the pile is found to be deteriorated below the cut line, a steel pile would be driven.over the "stump." It is anticipated that an impact or vibratory hammer and crane barge would be usedto install the pile. If the pile is found to be sound below mudline, a steel pile sleeve would be,;placed over the pile stump: The'steel sleeve may be installed using a crane or with smaller equipment. A new timber pile section would. then be attached to the steel pile sleeve and would support the bent cap. As an alternative, if the existing, damaged timber piles can be completely removed, new timber Piles would be installed. It is not possible to precisely identify which parts,of the trestle'would be repaired and retained and which would require replacement due to the unknown timeframe foractual construction: The trestle 13 Page 4 • • is deteriorated and, as time passes, thedeterioration rate could'>iricrease; what maybe repairable today would need to be replaced in a few years. The existing track will be replaced in its current alignment with as many ties;as are:in'reusable condition (estimated around 50%) and the deck boards and joists will'be completely replaced. In Alternative 1, the stringers and bent.caps wouldbe.assessed for extent:of deterioration and reinforced or replaced in-kind as needed. At this time, the,condition of all the wood components have been assessed by visual means, "sounding" (striking with:a hammer) and:some limited resistance testing. All three methods have an objective and scientific approach,.but since all of the components are not accessible to be tested from all angles, and'some are not reachable such as the stringers, reasonable assumptions must be made about Their condition. Theactual condition would not be known until the time that-the trestle is,dismantled. There are several components•of the`'trestle.that are mutually exclusive of all three alternatives and were discussed at the public meetings. • The existing steel rails will be replaced in their current alignment. • The railing is not an original component of the structure andsince there was no railing during the active original use of the trestle,there is no historic:,fnaterial tosave and no design to copy. Current building codes set certain requirements of the railing design upon the project. At this=time,,staff is intending continuation of the edge railing installed a few years ago during the Water Street Plaza project, or Semetliing similar to maintain consistency. • Some members of the public have suggested the addition of a mid-span pedestrian bridge in the area of a historical spur railroad line split off the trestle; heading south, approximately between First and Second;Streets, paralleling both.. The.mid-span pedestrian crossing was further investigated and,:althoughboth desirable and feasible froth an engineering standpoint, the estimated costs for planning and design prohibit inclusion into the project at this time. It is not evaluated in the MND because its cost is prohibitive. • The fender piles are an existing line of solid timber piles, spaded approximately four feet apart, and approximately four feet from thetrestle structure 'They are not attached to the trestle and most of the connections between each fender pile has deteriorated and disappeared. The original,purpose was to act as a fender to the trestle, in the same manner as a fender on a car, when barges and boats,docked for goods loading/unloading., Many of these piles have been tied back to the bank or trestle.as they deteriorate andlean onto the floating docks. This line offender piles is visible from across the,Turinhg+Basin, however, they are not required for any structural purpose. .These originalpiles=could be left in place and removed as they become a.nuisance. This,is'not.recommended however, as working around any original materials will impact the,construction.process. It;is,staffs intention to include construction of replacement fender piles as an alternative bid-in the construction documents. This.will allow City Council to decide on inclusion of the fender piles atthe time of contract award. The project for purposes of primary study in the MND is Alternative 1,but Alternatives 2 and 3 are also considered for informational purposes. A CEQA.initial:study and Mitigated Negative Page 5 14 Declaration ("MND") have been prepared and published for public,comment„and=is discussed below. Although the'City Council is the decision Maker-ion-the, ' 1 D, asked to review it and provide any comments that relate to historical resources, Staff willpresent the Historic and Cultural Preservation Comm ittee's;recommendation on a specific alternative and the MIND to the City Council which will act on,the environmental document: Staff would then provide direction to the engineering design-firm to begin the rehabilitation design process, as funded by the current`grant,"with completion intended for the end of the calendar year: The State Coastal Conservancy grant requires close-out by.March431,-201'3. Funding for construction has not been identified for this project, and'the;construction phase is not included in the approved CIPbudget for FY 12-13 or the CEP five-year plan: However, approval and design of an alternative and the completion of environmentaP.review•will allow staff to conduct a focused search for and apply to,granting agencies for construction funding. It is expected that the 'funding needed would come from multiple sources. The Coastal Conservancy has indicated interest in providing matching funds provided that:bond funding is available. • STAFF ANALYSIS. GENERAL PLAN The property is adjacent to Petaluma Historic Commercial District suspended over the Petaluma River running parallel to the westibank+of the River. The adjacent land use classification is Mixed Use. Although the trestle is referenced many times in the •General Plan and the subject of photographs, it is not identified in any of the figures mapping the City, The project is located within the 'Central Petaluma Specific Plan subarea, which includes the Turning Basin,and the Petaluma River; and aims to focus on the River as an amenity and linkage within the City. The following General Plan Guiding Pnnciples are applicable to the proposed project • Preserve and enhance Petaluma's historic character. • Enhance the Petaluma River corridor while providing recreational and entertainment opportunities, including through active implementation of the Petaluma River Access and Enhancement.Plan. • Simulate and.increase,public access and use of,pathways'as alternativectransportation routes by providing a safe, efficient, and intercounected• railsystem. The following GeneralPlan policies are applicable to the proposed project: 1-P-44 Develop,the PetalumaRiveras apublicly-accessible green ribbon, fronted by streets, paths, access points, and.open,spaces, byimplementing the,Petaluma River Access and Enhancement Plan within'the context of the PRC Design Standards. 2-P-3 Maintain landmarks and aspects of Petaluma's heritage that fosters its unique identity: Reinforce:the industrial character of the City by adaptively reusing and preserving industrial landmarks such as... Petaluma arid Santa Rosa Railroad trestle. 15 .Page 6 2-P-1'1 Encourage and :support the rehabilitation and development• of buildings and structures reflective:of the history of Petaluma's richtagricultural and river-oriented industrial,past and present,such as the Petaluma and Santa Rosa Railroad trestle as a boardwalk and/or Trolley line. 2-P-18 Develop Downtown uses and activities that relate,to the City's history: Continue the Preservation, rehabilitation, and reuse of historically:significant structures within the Downtown. 2-P-43 Provide additional pedestrian/bicycle access to and along;the riverfront to connect to existing and future trails toward Downtown. 5-P-53 Support efforts to a local trolley line utilizing the old spur line into the Downtown area. The rehabilitation of the trestle will be consistent with, and assist in the implementation of these guiding principles and policies. CENTRAL PETALUMA SPECIFIC,PLAN The property is located adjacent to the Urban.Center (T-5) zoning district as,outlined in Section 2.10 — Zoning Map in the Central Petaluma Specific Plan (CPSP):. :One,,of the primary planning goals within the CPSP is ito encourage a'stronger link between the city and the river. Further, the CPSP "encourages the rehabilitation and reuse of architecturally interesting structures:" The following CPSP policies and goals are applicable to the proposed project: Policy 3.6 Encourage tlie,developinent of heritage trolley service. Policy 4.4 Encourage development of heritage trolley service. Public Space &River Access Goal 1 Establish a continuous and interconnected system of public spaces,along the river: Goal 2 Utilizing publicsspaces-to extend the amenity of the waterfront inland. Goal 3 Provide urban public, spaces that serve multiple services: "The Water Street. trestle/promenade, on the west side of the Turning Basin, should'be.restored." Circulation Policy 3.3 :Establish'a,pedestdan oriented promenade around the Turning Basin. Historic Preservation Goal 1 Protect, enhance, perpetuate, and adaptively reuse properties of historic and architecturahsignificance. Objective 2 Preserve, the ,industrial and commercial complex: of structures, including the resources-Within the Petaluma Historic.Commercial District. BICYCLE:AND PEDESTRIAN'PLAN The project will assist with usability of the River Trail within,the Area and help further the completioir,of one+of the five top priority trail projects.' • 16 Page 7 The State Coastal Conservancy is in the process of establishing"the Bay Area Water Trail which terminates on the northern end in Petaluma, directly across the T11-filing.Basin froth the trestle. HISTORIC DISTRICT GUIDELINES The project is"adjacent to the Downtown!Commercial Historic Districts The restoration of the trestle will provide for the continued presence of this historic element within close proximity to the Downtown Corniiercial Historic.District. RIVER ACCESS ANWENHANCEMENT PLAN This plan was adopted in 1996, after the railroad had ceased sending-freight down the western spur, but before the trestle was closed to public access.= The references within this plan discuss gaining ownership of or access to the trestle deck. Downtown Segment Policy 1 Provide a continuous.banktop loop trail around the Turning Basin with pedestrian amenities such as benches and interpretive"signage. Policy 16 Strengthen and broaden physical relationships between the,river and the downtown. Policy 16c Promoteenew development., redevelopment and 'activities that will add vitality and pedestrian activity along the river. SECRETARY OF THE INTERIOR'S STANDARDS The Historic Resource Evaluation "(Attachment 2) was completed at the outset of the current project to determine the historic resource eligibility of the downtown trestle to the National Register of Historic Places and the California Register of Historical Resources. In summary; the trestle appears to be eligible for the Califomia'.Register, but not eligible for the National Register. The Standards Evaluation'(Attachmenti3) compared the three alternatives developed to the Standards for the Treatment of Historic :Properties and documented the applicable Standards for each alternative. Further description of,the potential impacts on historic resources using the Standards is contained in the MND and the CEQA discussionbelow. PUBLIC COMMENTS A Public Notice of the City's intent to adopt a mitigated negative declaration`for the.Project and the public review period on the MND was published in the.Argus•Courier on June"14,2012 and mailed to owners and occupants within„500 feet of the subject property. Public comments submitted after the Committee hearing but within the 30-day public-comment period will be considered by the City Council. ENVIRONMENTAL REVIEW A 'CEQA initial study and Mitigated Negativ •'Declaration (MND) has been prepared consistent with guidelines � ew decision m k n theMND, he CPC sasked to revi the document and provide any comments j ielated to historic resources. This Initial Study has not identified any significant and unavoidable impacts as a result of the proposed project and therefore•has not°resulted' in,thepreparation of an Environmental Impact'Report`..(EIR). All project”impacts are able to bedmitigated'to a level of less than significance., Neither,the"CityEnvironmental Review Guidelines nor CEQA guidelines require that a MND will,have Planning Commission or Historic and Cultural Preservation Cornmittee hearings when the,associated,project is at the discretion•of the City Council. However, staff has • • 17 Page 8 referred the MND for,theDowntown Railroad Trestle Rehabilitation to the HCPC for their input and reconrrriehdation on'those,aspects of the document thafrelate'to historicpreservation. All projects receiving federal funding are required to complete review consistent with the requirements of National Environmental,Policy Act(NEPA). Althoughconstruction;funding for the Trestle Rehabilitation'has not been identified at this time, aspotential:grant source could be a federal agency and therefore,,staff thought it prudent to include NEPA review requirements within the environmental review document. While CEQA does not require analysis of project alternatives in an IS-MND, an Environmental,Assessment under NEPA must include discussion of alternatives, including a No Action Alternative, as required under Section 102(2)(E) of NEPA(42 U.S.C.§4332(2)) and CEQ.Regulations §,1502.14(d). This requirement supported the development of the three project alternatives for'environmental review and,as<outlined'in the attached IS-MND. The Draft Conceptual Design for Rehabilitation of Petaluma Trestle included three alternatives for rehabilitation-of the trestle"structure:;Alternative 1 Rehabilitation,Alternative 2 Trestle Replacement, and Alternative 3 Complete TrestlerReconstruction. Alternative 1 i the trestle rehabilitation project as described:in,the EA/IS (the Project).,Alternativel2 would install new piles adjacent to,the,existing piles, leave the existing piles to deteriorate in place, reuse those parts of the remaining structure that were inygood condition, and replace in-kind those that were not Alternative 3 would replace all components of the trestle with new components. All other components(slope stabilization repairs, educational features,etc) of the project would-remain the same between alternatives. The Trestle is significant at the national level under National-Register significance Criteria A and B. Under Criterion A, it is.historically significant because of its association with Petaluma's tirne of great economic expansion;.when'it was declared the"World''.Egg Basket"-, The Trestle is a surviving,symbol of the agricultural and cormnercial:strength,that made the city a prosperous regionahtransportation center for the movement of agricultural and manufacturing,goods through SonotnaCountyand the greater Bay,Area Under Criterion B, the trestle'is historically significant for its association with George P: McNear, whose family has left behind an:impressive legacy of elegant historic buildings;;publicopen spaces, and even,the configuration-of the Petaluma River itself. • In addition to the significance criteria required forNational Registereligibility, a property must also maintain integrity in order to qualify for listing. There are,seven qualities of integrity; location, design, setting,.matcrials;.worlonanship, feeling, and association. Although all aspects of integrity aie,not required for,listing,;a,resource must maintain a strong overall sense of integrityto,,qualifyfor listing. The;Petaluma Trestle Histonc Resource Evaluation completed.byPreservation Architecture. in 2011 (Attachment-3)lconcluded that the resource retained integrity,of location, setting,and association;but not for the other four aspects. Therefore,the evaluation concluded that the trestle lacks integrityand,does'not individually meet the'criteria'for listing on the National Register. The Trestle'has=beendetednined eligible:for listing on.the California Register under..Criterion;1 for its association,withPetaluma's time of growth as the "World's Egg Basket,"under'the themes of agriculture,industry, commerce;tand'transportation. Additionally, under Criterion 2 the Trestle is eligible for its association with George P. McNear, who is,indelibly linked to the development of the Petaluma&;Santa RosaRailroad Company and the subsequent construction of the West Petaluma,Spur and associated,.Trestle. The California Register does not require"the same finding of integrityas theNational Register.. The Trestle has been determined to retain potential to yield Page 9 18 liistoricjinfonnation°and,therefore.maintains eligibility fOr individual li'stin g on,the California Register-. As outlined in the IS;,MND the Trestle Rehabilitation Project was determined;to.have a less than significant impact onthe historic resource because it was designedin accordance with the Secretary of the Interior's Standardsrfor Rehabilitation. More specifically,the project Will result in the property being used as;itwas historically; the,historic;character of the;property will be retained and preserved, the distinctive=materials and construction techniquesthatacharacterize the property will be preserved, the distinctive historic;features will be repaired rather than replaced, and the related new construction will be designed to be differentiated from yet compatible with the old. Under CEQA,projects that are determined°to meetttheSecretary of the Interior's!Standards are considered to be-mitigatedto a lesa,than significant impact on'the historic,resoiirce: Although'no archaeological resources were:identified within the;project area, several mitigation measures.are included in.the MND'to'cover accidental discovery:of Human reinains,,documentatien of the trestle prior to commencement of construction, and requirement tohave;a qualified archaeologist on site to+monitor all grading activity. • A Standards Evaluati'on(Preservation Architecture'2012) (Attachment 4) was prepared to evaluate the alternatives. Alternative 2'was found-not:to,be consistent with the Standard for the Treatment of Historic Properties..Therefore, there would have been the potential for Alternative.2 to have a significant adverse impact or-1'U historic resource:,In addition, because Alternative'2l placed new piles alongside:existing pileslimpacts to wetlands would potentially be greater: Consequently Alternative 2 remoVatnith'fitttlief consideration. The Standards6Evaluation did not reach afinal conclusion on whether.Alternative 3=was consistent with the;Standards, stating that additional information.regarding`the design,was required for'a final determination':,Based'on the information provided in the Draft Conceptual Design:it could'°°not be determined if Alternative 3 would comply with Standard 3 for-Reconstruction: Will the project include measures to preserve any remaining Iiistonc:materials,features,;and spatial relationships. It was outside`the scope of the Dr aft' Design;report to identify the outcomeof any remaining historic materialnfter:dismantling of the'Trestle. Therefore, Alternative 3 is considered to`have;a greater impact on historic resources'thanthe Project(Alternativel). The No.ActionAltemativewould:have none;of the environmental impacts described m the analysis, buf.also would:not fulfill theobjectives in.the Purpose and Statement,which is<to rehabilitate the Trestle forits historic andriver'-front use=in ordance with:the CitjofPetdlurna'GeiierdLPlki`z 2025!and other,Cityadopted planning documents: • RECOMMENDATION ;Staff recomrnends; That the ;Historic and Cultural Preservation Committee recommend the. rehabilitation alternative:approach (Alternative I) for the Downtown Railroad Trestl'e=Rehabilitation Project located'on the ,west banhrof the Petaluma=River for Petaluma City Councils consideration.
