PURPOSE Petaluma is a river town. The Petaluma River is its lifeblood. `' D0INNTOWN WATERFRONT - M SHOWPLACE OF THE CI TY' HISTORIC RIVERFRONT WAREHOUSES & BOARDWALKS d MCNEAR PENINSULA - RIVERFRONT PARK & MARSH 3 E XHIBIT R The overriding purpose of the Petaluma River Access and Enhancement Plan is to describe this community's vision for the Petaluma River, including its riverfront uses, activities, and developments. Implementation of this plan will result in a waterfront environment that is the jewel in Petaluma's crown. This plan elaborates on the Petaluma General Plan 1987 -2005 regarding the river and the properties abutting it. As the most comprehensive statement of this community's vision for the river and riverfront development, this plan will be used by policy - makers, property owners, and interested citizens to guide the metamorphosis of the river into the central feature of Petaluma. 1.0 Plan Summary In order to achieve the vision of this plan, the city must balance four principal components of the General Plan's directives: * Restoration and preservation of the natural resources. * A pedestrian walkway and bike trail for the entire length of the river within the city limits. * A vibrant, high density water- related commercial environment with combined tourism, recreation, commerce, and industry in and around downtown by the year 2015. * A mixture of different uses and activities along the entire river corridor that complement the riverfront location. During the past half - century, the Petaluma River became a sadly neglected resource. Where once the city turned toward the river for its very life, the city began to turn away. Substantial opportunities to provide recreational and commercial services to a society with changing tastes, changing needs, and changing habits were too often. ignored. In recent years, efforts of local government, community groups, and individual entrepreneurs have begun to address the fact that there is tremendous potential for this river -- and potential to provide long- lasting benefits for the citizens of Petaluma. To date, there has been no blueprint or comprehensive vision to guide future use and planning for .this vitally important waterway. The River Plan is designed to provide that blueprint. Implementation of this plan will result in a riverfront with people near the water, enjoying its presence and actively engaged in walking, 4 Petaluma River Access and Enhancement Plan boating, working, dining, or shopping -- whatever the activity -- with a he sense of place and relationship to the natural environment. This plan bases Petaluma's future relationship to its river on models of historic active waterfronts combined with modern environmental sensitivities. Described in this plan are various means of enhancing the river, encouraging compatible developments along the river frontage, creating and maintaining a system of river - related public trails and direct riverfront access, and other methods of achieving goals of the Petaluma General Plan Over0 000'people enjoyed the tenth annual River Festiva! at ! • ;. the downtown waterfront in August, 1995. The people of Petaluma are rediscovering their riverfront as a central community amenity and'gathenng place. p 1.0 Plan Summary 1.2 FORMAT OF THE PLAN The Petaluma River Access and Enhancement Plan is organized" to be consistent with the format of the Petaluma General Plan 1987 2005 Statements that guide future actions have been separated into goals, objectives, policies, and programs. This hierarchical approach allows the public and City decision - makers to distinguish between the desires of the, community with respect to the river (stated as "goals" and "objectives ") and the methods through which these desires can be achieved (stated as "policies" and "programs "). Petaluma River Access and Enhancement Plan Chapter 3, Goals, Objectives, : Policies..' �& .: Programs, provides the core::: regulatory; features of the plan. The overalf'Systemw de policies that apply to the entire river corridor: are discussed in the first part of the chapter; while the policies and programs* ,specific`; to individual River Segments are described,in -the. . second part of the chapter. Projects proposed along the river will be subject to systemwide directives as well as those for the specific river segment. 6 '1 I r i Petaluma River Access and Enhancement Plan 1.3 RIVER PLAN AREA The subject of the River Plan is the 6.5 -mile long, 800 -acre section of the river and abutting properties that lie . mostly in the City of .Petaluma from the Old Redwood Highway road bridge over Willow Brook Creek near Redwood Business Park to the Petaluma Marina at the Highway 101 bridge. The river plan area (or river corridor) includes the river, its banks, and all properties that either directly abut the river or are. near enough to be affected by the provisions of this plan (see River Segment. Map page 18 and 19). Within the river corridor are industrial and commercial land uses (some that relate to the river and some that do not), the historic downtown,commercial and warehouse,districts, remnant agricultural areas, residential areas, riparian vegetation, existing and planned open spaces, and recreational facilities. The greenway created by this plan is that part of the river corridor where flood waters are accommodated and where river front public access and habitat enhancement are recommended. The greenway includes the river ehannel and its banks, flood protection alterations, the trail and access amenities, habitat protection and enhancement zones, :public parks as designated on the General Plan, and a buffer zone between the top of bank and the adjacent development. 1.0 Plan Summary Setting The headwaters of the Petaluma River are several miles northeast of the City of . Petaluma. The river flows first through gently sloping farmland, then through the center of the city,' and finally, bordered by levees and salt marsh, past agricultural fields and small residential areas to San Pablo Bay, approximately fourteen miles from downtown Petaluma. It' drains a watershed of approximately 32 square miles. Tributary streams are seasonal in the upper reaches of the watershed, but intercept groundwater in the flat valley landscape and sometimes flow year -round near the downtown area. There, the freshwater mixes with the salt water that flows up from the bay with the tides. Levees, cultivation, channelization, and urban development have significantly altered the natural riparian and wetland habitats that once flanked the river.

There is evidence of significant early Coast Miwok settlements along its banks. just upstream of the downtown area. Later, shipping of goods in support of miners and settlers led to the development of the colorful historic downtown along its banks. Agricultural, industrial, and other commercial enterprises, dependent upon the river for shipping, flourished along the river from the late nineteenth to the early twentieth centuries. The river tied Petaluma to the outside world with paddlewheel steam ships, barges, and scows transporting Petaluma's agricultural bounty and manufactured goods to the outside world and bringing many necessities of life to the young city. The city grew outward from the bustling waterfront in a pattern responding to the location, activities, and shape of the river. I An old Coast Miwok village and an early 20th century farm are i found at the Cedar Grove property, just upstream of the granary towers and downtown Petaluma, seen in the distance. The River Plan encourages recognition of historic sites and i events along the waterfront. Petaluma River Access and Enhancement Plan The Great Petaluma Mtll and Steamer Gold are typical of the historic buildings'facing• the river that define the character of the downtown waterfront. JEJ E X - PH ID Old warehouses and wharf pilings are a common site along : the riverfront near downtown. Petaluma River Access and Enhancement Plan While most of the active river - dependent businesses have now disappeared, many old riverfront buildings remain. ' Downtown's development pattern is still inextricably linked to the river. Several viable river - dependent businesses remain, keeping up the tradition of an active working waterfront. The collection of old buildings hugging the banks of the river, a historic downtown that reminds us of the river's - prominence in the town's formative years, active waterfront industries, and the heritage of riverfront settlements create the unique urban character of Petaluma. Today, this character supports a bustling pedestrian- oriented commercial center and increasing tourist trade. Some of the largest remaining areas of open land within Petaluma are located along the river. Future use of -these properties, like those found in the historic downtown, will also be linked to the river and its riparian habitats. The river will continue to be a central organizing feature of the city as it grows. 1.0 Plan Summary The River as a System In the planning area, the Petaluma River is typical of urban streams in which water, plants and animals, and human activity interact as a dynamic system. The River Plan will enable all of the components to thrive interdependently, each enriched by the others and their relationship to the river. As envisioned, the river corridor will again become the most significant -unifying feature of the city. It will provide peaceful settings amid nature, scenic backdrops to active workplaces, and an invigorating pedestrian and bicycle pathway network connecting many centers of activity within the city. If properly planned and cared for, the river will flourish as a life supporting habitat corridor and a focus for human interaction, commerce, and transportation. This plan, recognizes that the river corridor described in this document is only one portion of the entire river system.. Actions taken within this area will affect and will be affected as well by the upstream and downstream reaches outside the City of Petaluma's jurisdiction. The view across the -river from the end of 'G' Street includes oak Creek Aps,,;nents, lust upstream o!

ERBIT Petaluma River Access and Enhancement Plan 1.0 Plan Summary 1.4 GUIDING CONCEPTS OF THE ACCESS AND ENHANCEMENT PLAN Through an aggressive public information and outreach process, the community's vision for the Petaluma River was gradually revealed. Consideration of the emerging themes guided the planning and design concepts for the plan. The following description of these themes is provided to give readers a conceptual framework for the regulatory text contained in Chapter 3. Diversity: Urban and Wild The river corridor is diverse and complex. Its richness reflects the . heritage of local development patterns as well as the nature of the river itself. An important concept of the River Plan is to accept and build upon this heritage of diversity in a manner that will create a cohesive, mutually supportive whole. Urban features will be interwoven with the natural and wild, each contributing equally to the character of the Petaluma River corridor. Complementary Riverfront Developments Developments that feature the river as an integral component of their design are encouraged. New developments should build upon the city's authentic waterfront heritage. A revitalized, bustling urban waterfront in the downtown area will be supported by riverfront commercial, industrial, recreational, and residential activities throughout the river corridor. 17 A11BIT The Foundry Wharf features its river frontage and is a model . for other coinplem`entary riverfront developments. The natural riparian area no' ar the upstream railroad trestle is a prime wildlife habitat that will be expanded. Petaluma River Access and Enhancement Plan 1.0 Plan Summary Education/Interpretation The river's importance as natural habitat and its historic, cultural, and economic significance within the city provide rich material for learning about the region. Key topics of interest in the river area are Coastal Miwok activities, the history of later settlements, development of agricultural and industrial economies, use of the river and railroad - as transportation systems, hydrology and geology, and the river's ecological functions. In addition, the current process of planning for, protecting, and restoring the river can be described as part of any public interpretation program. City Gateways The Petaluma General Plan recommends the creation of "gateways" at important roadway approaches to the city. These areas impart a sense .of entry to Petaluma and provide local information through extraordinary design, signs, and landscaping. Major river crossings and other points with distinct views of the river should also serve as gateways that link the river to the visitor's first impression of the city. Other river crossings or views can be similarly highlighted to orient and educate the viewer. The river corridor will be a continuous unifying element in the city's, urban design, connecting such otherwise disparate elements as the historic downtown . and riverfront industry to salt marsh habitat and oak woodlands. Gateways to the river will help orient visitors to their location within the city as well as to the city's place in the Petaluma valley and North Bay Region. Recommended gateway improvements at the Washington Street bridge entry to downtown include riparian tree planting, expanded pedestrian, areas and amenities, informational signs, trail links, and framed views of interesting buildings. 13 bV E'X- 1 1 11 1 A city gateway along Petaluma Boulevard North at Stony Point Road would feature the restored riparian forest and could Include a staging area. 1.0 Plan Summary Petaluma River Access and Enhancement Plan Continuous Trail System The River Plan will unite the 6.5 mile river corridor with a continuous trail .system for bicyclists and pedestrians. The trails will link together neighborhoods, places of employment, commercial and cultural facilities, parks, and natural areas into a coherent system of amenities serving locals and visitors alike. A variety of direct water access points will encourage recreational and commercial activities throughout the river corridor. The river trail offers connections. to a wide network of trails extending throughout the city and region. Ties to'the Bay Are Ridge Trails and Bay Trail are encouraged. .

Landscape improvements in urbanized areas will also be designed to provide habitat. Bank stabilization and flood protection activities will utilize techniques that help support healthy environments appropriate for that property. Within the city, river habitats vary from. tidal salt marsh to fresh water stream. Linking these disparate areas into a linear continuum will provide untold benefits to the health and quality of the entire river eco- system.

It will take many years to accomplish and require multiple phases of public and' private investment and action. Most portions of the plan will be implemented by- private development activities as they occur over time on riverfront,properties. Utilization of the river as both a visual and recreational amenity, as well as a travel- and activity corridor, will add value to adjoining properties, offsetting the burden to the property owners of implementing their portion of the plan. Initial public funding is recommended for high visibility- and high impact improvements °in or near the downtown area. Success with the earliest improvements will spark enthusiasm to carry out future phases of the plan. The River Plan coordinates each incremental improvement into a cohesive whole. Waterfront improvements In the vfcinfty of downtown are recommended as first priority public investments, such as public access at the end of V Street in the Warehouse Segment. 1.5 RIVER SEGMENT'S For planning purposes, the river corridor has been divided into six segments,, each with distinct characteristics and internal similarities that allow logical clustering of design and planning policies. In Chapter 3, goals, objectives, policies, and programs are provided. for the entire access and enhancement plan area (systemwide) as well as for the individual river segments. The planning and design concepts for each of the segments are summarized . as follows: 1. Upstream Segment (Chapter 3.3) The Upstream Segment, the largest of the six segments and the one most likely to change significantly in the near future, contains remnants of an extensive riparian forest that marked the river's course through the broad valley landscape. The remaining groves of trees are.recognized as unique resources to be protected and enhanced, and will supply the stock from which a continuous riparian forest will be re- established along the greenway. The open rural /agricultural land uses in this area are gradually being replaced by higher density centers of employment, commerce, and residential growth. The River Plan acknowledges this pressure for change and recommends an integrated approach for new complementary development to with riverfront public access, flood mitigation, and habitat preservation /enhancement. Improvements in the greenway will become an integral part of each parcels' site design. 17 6A '. k 1.0 Plan Summary Petaluma River Access and Enhancement Plan Open land in the Upstream Segmentdike , this : Corona Reach river frontage, is under pressure to change.

Payran Residential Segment (Chapter 3.4) Comprised primarily of residential properties with houses and yards very close to the river banks, this area has been repeatedly subject to extensive flooding. The U.S. Army Corps of Engineers (COE) has prepared Payran Reach flood control recommendations for the City. The River Plan is prepared with the , COE flood control plans in mind. For instance, it is recommended that one maintenance road act as the trail route. At the former Cedar Grove Park there is evidence of a significant Coastal Miwok village and an old, intact farm complex that represents the town's earliest settlements. The Petaluma General Plan identifies this property as a potential park site. The River Plan recognizes the site for its potential public access to the water and historical /educational attributes. This segment represents a transition between the forested freshwater riparian habitats upstream and the open brackish tidally influenced habitats downstream. The River Plan recommends integration of new development with riverfront public access, habitat preservation /enhancement, and flood mitigation activities. Petaluma River Access and Enhancement Plan 3. Lakeville Industrial Segment (Chapter3.5) This segment is a transition between the residential areas upstream that still contain some riparian habitat, and the more urbanized, pedestrian orientated downtown iy area. It is primarily an industrial erfront that,. like the Payran Residential Segment, will be partially affected by the COE flood project. This area, with its prominent feed processing industries, illustrates the important role of agriculture in shaping Petaluma. The trail and greenway through this area will be secondary to maintaining these industrial activities. Habitat restoration and beautification through increased landscaping are encouraged, especially just upstream of the Washington Street bridge although the design of:: the greenway will emphasize 2the industrial character of this segment. Historic buildings along Water Street Segment can re- orient to the river a pedestrian promenade replaces parking. - -._.- ----- _._ - - - --- - - - - - -- Riverfront improvements around the Tuming Basin in the.: Downtown Segment will make this the primary destination of the trail system and activity center of the river corridor. p Petaluma River Access and Enhancement Plan 1.0 Plan Summary 4. Downtown Segment (Chapter 3.6) This segment covers the waterfront of the city's traditional and historic central business district. This is the primary, destination of the trail system and activity center of the river corridor. Recommended in this plan is the completion the existing system of docks, boardwalks, and overlooks surrounding the Turning Basin in a way that builds :upon the historic downtown development The historic character of the commercial - riven'ront in the Warehouse Segment, as seen from the 'D' Street bridge, will be retained with riverfront boardwalks to replace . the decayed wharves. Retention of river dependent industries and.their barge traffic is a priority in the Downstream Segment, as well as acquisition of McNear Peninsula (on'the right) for a park and marsh restoration. patterns and creates, urban open spaces that are full of activity, It encourages further reorientation of the buildings toward the river to heighten the area's vigorous, bustling commercial and recreational activities. Downtown waterfront improvements are recommended as early components of this plan as a catalyst for improvements in other segments. 5. 'Warehouse Segment (Chapter 3.7) The downtown Warehouse 'Segment, located along the western side of the river from "D" to "H" Streets, provides a unique river frontage with the peaked roof warehouses at banktop and decaying wharf pilings at the water's edge. This plan calls for a new riverfront boardwalk to replace the decayed wharves of a bygone era, improved water access at the ends of "F", "G ", and ''H" Streets, and building ventures that accentuate the historic character of this mixed use neighborhood. Improved pedestrian access between this segment and downtown will spur rehabilitation and bring new economic vitality into this area. 6. Downstream Segment (Chapter 3.8) Besides containing some of Petaluma's largest industries, this riverfront segment also has extensive undeveloped land, including the 32 acre planned city park on McNear Peninsula. In this segment the river is a. broad tidal slough, periodically dredged for navigability, amid a landscape of commercial and heavy industrial establishments with barges; recreational,, and commercial boat traffic. Greenway improvements such as bank stabilization, trails, and revegetation depend greatly on the nature of development along the river. Maintaining authentic industrial waterfront activities, visible from the trail, is . a priority of the River Plan for this area. Early acquisition and improvements to McNear. Peninsula for public use is a high priority. 21 0 EB I 3.6 Downtown Segment Goals, Objectives, Policies, rand Programs Petaluma River Access and Enhancement Plan COMBINED PEDESTRIAN BICYCLE TRAIL PEDESTRIAN ONLY TRAIL b D t7 p p 0 TENTATIVE LONG TERM TRAIL WATER SURFACE COMBINED BUFFER & RESTORATION ZONES OAK GROVE /RIPARIAN WOODLAND PRESERVATION ZONE TO RIDGE TRAIL: MARSH POTENTIAL FUTURE i TRANSIT "STATION NEW SIGNALIZED INTERSECTION BIC YCLE PARKING M r WATER ACCESS u THROUGH j ROUTE O E Existing NEW Proposed O SIGNALIZED s' a INTERSECTION GATEWAY ) ' COPELAND STREET STAGING AREA CROSS SECTION NEW BANKTOP ASH � BOARDWALK y .

"It should be the showplace of the city." Participants in Neighborhood Meeting and Community Workshop, 1992 The centerpiece of the river plan, the Downtown Segment, extends from Washington Street to the "D" Street Bridge. It includes the river edge of the city's central business district; the heart of historic Petaluma. The river frontage includes lively gathering places and commercial enterprises, the Balshaw Bridge, the Golden Eagle Shopping Center, the Petaluma Queen, the Great Petaluma Milli the River Inn, and the Yacht Club. Petaluma's unique character and charm, the basis of a growing tourist industry, are founded on its river heritage.. The Turning Basin,. the central open space, is the destination of boats from around the world, whose owners tie up at the docks to enjoy downtown Petaluma's restaurants, shops and historic waterfront. Visitors and locals gather here to celebratet the river. Historic buildings define the river's character. Cargo was unloaded from ships and stored here. Many buildings have been renovated with new, river - oriented uses that enliven the waterfront but other structures and 'open spaces remain to be improved. Water Street, for instance, is lined with handsome old buildings that can be opened to pedestrians. Downtown's future depends on the river. 99 mral L 1 El X111BI 3.6 DOWNTOWN SEGMENT 3.6.1 EXISTING SETTING
