The Cement Hill Tank is supplied by the Cement Hill Water Treatment Plants No. 1 and 2, which delivers water to Suisun City, the unincorporated area of Tolenas and the Suisun Valley. The Gregory Hill Tank receives its water from the Suisun City Distribution system which is pumped from the Benton Court Pumping Plant located in Old Town Suisun City with a pumping capacity of 1,000 gpm. The Gregory Hill Tank supplies water to the Suisun Valley through the Suisun Valley Pumping Plant at a rate of 400 gpm and/or gravity feeds back into the Suisun City distribution system. The Sports Complex Tank is a supplemental ground level storage tank with a pump to boost into the distribution system at 2,000 gpm. The Suisun City Corporation Yard tank is also a supplemental ground level storage tank with a pump to boost into the distribution system at 1,200 gpm. These facilities would provide a peaking storage of 20% and an emergency storage of
approximately one full anticipated maximum day demand, and will also provide fire storage of 420,000 gallons. The table below lists the facilities in the SSWA water system.

As a result of a condition assessment conducted by the SSWA in 2012, it has been determined that an additional Cement Hill Tank, Cement Hill Tank 2 is needed to meet demands.

Service Demand
In December 2012, the SSWA completed its Water System Review, a report which projected updated information on the anticipated growth and development within its service area, as well as a revised estimate for water demand. Based on a review of historic water use records over the last 15 years, the Annual Average Day (AAD) demand of each year was used to calculate respective factors for the Maximum Month and Maximum Day demands for each year. Table 5-3Table 5-3 identifies the estimated peak build-out demand, which was calculated using the highest demand factors occurring over the last 15 years (SSWA 2012: 4). 184
Chapter 5 | Open Space + Public FacilitiesCivic and Services

Table 5-3: Water Usage Demand Factors
Source: SSWA Water System Review (December 12, 2012).

The ultimate maximum day demand is estimated at 6,470 gpm (9.3 MGD) for the service area. This represents a significant decrease from the previous figure of 11.08 MGD that was estimated in the 2007 Water Supply Options report (SSWA 2012: 6).

The SSWA water demand is anticipated to be less than available water supplies through 2035 in normal water years. As shown in Table 5-1Table 5-1, water supply is projected to be sufficient in normal water years over the UWMP’s 20-year planning period (i.e.,from 2015 to 2035). Although Table 5-4Table 5-4 shows that water supply in single and multiple-dry water years is insufficient to meet demand within the SSWA service area over the 20-year planning period, a joint powers agreement between SID and Suisun City ensures that water will be provided from the SID water supplies and therefore there will be sufficient water supplies to meet demands (SSWA 2011:66). A footnote in the UWMP indicates that:
“The apparent negative supply totals are a result of the methodology used for calculating supply reliability. In fact, per the joint powers agreement between SID and City of Suisun City the commitment has been made that water will be provided for the service area from the SID supply and therefore there will not in fact be a water shortage” (SSWA 2011:67).

Section 3.0 of the 1990 SSWA Implementation and Lease Agreement states that the “City and District may agree to add additional lands to the Joint Service Area covered by this Agreement. Such action shall be accomplished only by amendment to this Agreement or by a separate written agreement...” According to SID, this process would require future negotiations to an amendment of the JPA.

Water demand is anticipated to be less than available water supplies through 2035 in normal water years. A joint powers agreement between SID and Suisun City ensures that water will be provided from the SID water supplies and therefore there will be sufficient water supplies to meet demands.

Conservation & Legislation
The 2035 General Plan includes measures to ensure that sufficient water sources are made available to serve new development. The City will condition approval of new developments on the availability of sufficient water supply, storage, and fire flow (water pressure), per City standards and require demonstration of adequate long-term water supply for large development projects as defined in Water Code 10912(a). 186
Chapter 5 | Open Space + Public FacilitiesCivic and Services

The City will also require the use of water conservation technologies, such as low-flow toilets, efficient clothes washers, and efficient water- using industrial equipment in new construction, in accordance with code requirements; encourage use of recycled water for outdoor irrigation, fire hydrants, and commercial and industrial processes; and require new development to incorporate climate-appropriate landscaping to reduce water demand. In addition, the City will comprehensively assess water supply and demand and identify a range of local conservation measures to be implemented through the UWMP.

In addition, the 2035 General Plan includes policies committing the City to ongoing water supply planning with Solano County Water Agency, Solano Irrigation District, and other local jurisdictions and initiating a study with the SSWA and the Solano County Water Agency to determine the feasibility of extending a connection from the SSWA water treatment facility to Suisun City so that the City may directly utilize its Solano Project water entitlement. The City will also support FSSD efforts to explore the feasibility of using treated wastewater for irrigation in parks, landscaped areas, and other appropriate locations.

5.2.2 Wastewater
The City of Suisun City and the Fairfield-Suisun Sewer District (FSSD) jointly operate and maintain the wastewater collection system that serves the City. FSSD owns and operates the trunk sewer system, which includes all 12-inch and larger sewers and the major pump stations and force mains that convey wastewater to the District’s wastewater treatment plant. FSSD also owns, operatesoperates, and maintains all of the pump stations in the City’s wastewater collection system. The City, along with the City of Fairfield and Travis Air Force Base, is a “satellite collection system” to FSSD and owns and operates only those 10-inch and smaller gravity sewers within its service area. The City’s portion of the system consists of approximately 74 miles of gravity sewer. The City does not own or operate any sanitary sewer pump stations or force mains.

Wastewater flows travel by gravity and are pumped by smaller stations to four major pump stations which pump wastewater to the treatment plant.

The wastewater treatment process includes screening, primary treatment, intermediate treatment by oxidation towers and intermediate clarifiers, secondary treatment with aeration basins, and secondary clarifiers and tertiary treatment via filtration and disinfection. Waste solids are thickened and treated in anaerobic digesters. Then, solids are further concentrated before being disposed at the Potrero Hills Landfill. Flow is continuously measured at the pump stations. On occasion, flow monitoring may be deployed into the district’s gravity lines to evaluate system capacity and surcharging during storms. Suisun City is served by the Suisun Pump station and three smaller stations: Lawler I Pump Station, Lawler II Pump Station, and Crystal Street Pump Station. 187

Within the last decade, numerous improvements have been made to the treatment facilities to increase peak capacity and improve upon the treatment process. A treatment plant project to replace chlorine disinfection with ultra-violet disinfection was completed in 2011. The Central-Suisun Forcemain Equalization Project, completed in 2013, increased the reliable peak capacity of the Suisun Pump Station from 31.7 to 38.3 mgd, allowing for more water to be processed. The Suisun Forcemain improvement project has enabled the pump station to meet current and near-term capacity needs until growth and revenue projections become more certain. New projects identified in the master plan will still be needed to meet long-term capacity requirements.

To date, system evaluation and capacity assurance of the City’s collection system has consisted of observation of sewer system performance during dry and wet weather and enforcement of the City’s design standards for new sewers. Capacity assessment has been handled historically by the Fairfield Suisun Sewer District for the geographic area including Fairfield, Suisun City, and portions of Solano County served by the District. In 2013, the District completed a Sewer System Master Plan (an update of its previous Master Plan completed in 2007). The Master Plan identified all parcels within the service area of Suisun City, land use type for each parcel, and the status of developed versus undeveloped. Wastewater flows generated by each parcel were calculated and imported into a hydraulic model of the sewer system.

The Master Plan utilized a hydraulic model to assess the current and future flows and capacity needs of all gravity sewers, 12-inches in diameter and larger; these larger trunk sewers have a greater potential for capacity deficiency due to extended tributary areas. The future evaluation and capacity assurance of City sewers will include continued observation of system performance during wet weather; expansion of the hydraulic model as needed, and enforcement of design standards to ensure that new sewers are sized with adequate capacity to serve new 188
Chapter 5 | Open Space + Public FacilitiesCivic and Services

development. In the future, the City plans to prepare a Master Plan for its sanitary sewer system, which will be coordinated with the District’s Master Plan and hydraulic model, in order to develop a capital improvement program to address any identified capacity issues.

The FSSD recently completed a treatment plant expansion that increased the average dry weather capacity from 17.5 mgd to 23.7 mgd and reliable peak-flow capacity from 34.8 mgd to 52.3 mgd. Currently there are no scheduled projects in Suisun City for collection system improvements.

5.2.3 Stormwater
The City of Suisun City Public Works and Building Department maintains an inventory of facilities and coordinates necessary improvements to ensure capacity required to serve new development. The City’s Stormwater Management and Discharge Control ordinance was enacted, with the intent to regulate non-stormwater discharges to the public storm drain system, protect the public storm drain system from spills dumping or disposal of materials other than stormwater, and reduce pollutants in stormwater discharges, to the maximum extent possible.

The City’s storm drainage system, which includes creek flows along McCoy Creek, Laurel Creek, and Union Avenue Creek, would likely be contained within the existing creek bank during a 100-year storm, except for localized flooding and standing water that may occur during brief, intense storms when runoff exceeds storm drain system capacity.

As a participant in the National Flood Insurance Program (NFIP), Suisun City is required to adhere to floodplain management policies that include sound land use practices. The Federal Emergency Management Agency (FEMA) administers the NFIP through the Federal Insurance Administration. FEMA produces flood Insurance Rate Maps (FIRMS) which identify flood hazard areas and restrict development in these areas for the communities participating in the NFIP.

FSSD and City Activities
The City’s Municipal Review Permit (MRP) was adopted by the Water Board on November 18, 2015. The MRP delineates requirements to ensure that storm water quality is protected. The breakdown of shared activities between the City and District are delineated through a Drainage Maintenance Agreement and are specified as follows.
 District Activities. District activities include maintenance of storm water pump stations, industrial and commercial site controls, public information and participation, water quality monitoring, mercury controls, PCBs control, copper controls, PBDE, and legacy pesticides control. The Sewer District has assumed responsibility for operation and maintenance of pump 190
Chapter 5 | Open Space + Public FacilitiesCivic and Services

stations located in Suisun City as defined under the “Regional Facilities” in the Drainage Maintenance Agreement.
 City Activities. Municipal maintenance, new development compliance, illicit discharge detection and elimination, construction site controls, pesticide toxicity control, trash control, exempt and conditionally exempt discharges. As detailed in the Drainage Maintenance Agreement, the City is also responsible for the maintenance of “Local Facilities,” which includes storm drain pipelines, box culverts, concrete lined channels, improved earth channels, natural creeks, detention basins, street sweeping, data management, and fencing. The City also maintains a number of open channel storm drains of varying sizes. The larger channels are blanketed with natural vegetation and require periodic cleaning. There are approximately 14,500 feet of large open channels and 20,000 feet of smaller ditches.

Upgrades to storm drainage pipes over the past 10- years include improvements required and funded by new developments. All new commercial and residential subdivisions are required to conform to the City storm drainage standards, protect water quality, and meet Regional Water Quality Control Board requirements. Among these requirements, in 2009, the San Francisco Bay Region Water Quality Control Board adopted the Municipal Regional Stormwater NPDES permit (NPDES permit)1 for the San Francisco Bay Region. The intent of the permit is to mitigate the potentially detrimental effects of urban runoff through site design and source controls early in the development review process and provide guidance in the selection of appropriate best management practices (BMPs).

Suisun City is the lead agency responsible for review of projects for stormwater conformance with applicable, laws, policies, and guidelines, including implementing the C.3 provision of the NPDES permit, which requires the City implement measures to reduce stormwater pollution and increased stormwater runoff, volume, and duration from new development or redevelopment projects.

Under the C.3 provision, new development or redevelopment in the City that creates and/or replaces 10,000 square feet or more of impervious surface (collectively over the entire project site), including commercial, industrial, residential housing subdivisions, mixed-use and public projects; and redevelopment projects resulting in the alteration of more than 50 percent of the impervious surface of a previously existing development, shall be required to implement LID source control, site design, and stormwater treatment measures, designed to treat 100% percent of run-

off for a project’s drainage area on-site or at a joint stormwater treatment facility.

The C.3 provision of the NPDES permit also allows projects alternatives to complying with the above standards under provision C.3.e through: (1) on-site treatment or treatment of a portion of the run-off for the project’s drainage areas with LID treatment measures at a joint stormwater treatment facility and treatment of the remaining run-off with LID treatment measures at an off-site project in the same watershed or (2) treatment on-site or treating a portion of the run-off for the project’s drainage areas with LID treatment measures at a joint stormwater treatment facility and paying an equivalent in-lieu fee to treat the remaining runoff through LID treatment measures at a regional project or a regional or municipal stormwater treatment facility that discharges into the same watershed as the project. The regional project must achieve a net environment benefit and must be constructed by the end of construction of a regulated project. If more time is needed, regional projects must be completed within three years after the end of construction of the regulated project and may be extended to a maximum of five years with prior Executive Officer approval.

The C.3 provision of the NPDES Permit also identifies incentive LID treatment reduction credits that apply to certain types of smart growth, high-density, and transit-oriented development projects or “special projects” (as defined in Section C.3.eii of the NPDES permit) that, at the scale of the watershed, can reduce existing impervious surfaces or create less accessory impervious areas and auto-related pollutant impacts.

For any Special Project, the allowable incentive LID Treatment Reduction Credit is the maximum percentage of the amount of runoff identified for the Special Project’s drainage area, that may be treated with tree box high flowrate biofilters and/or vault-based high flowrate media filters. Projects within the WDSP area could potentially fall into one or more of these three categories of special projects that may qualify for LID treatment reduction credits:
 Category A projects may qualify for a 100 percent LID Treatment Reduction Credit – these projects are designed to be pedestrian friendly; special projects creatinge or replacing replace less than ½ acre of impervious surface area; and located in a downtown core area, neighborhood center, or other pedestrian- oriented district or historic preservation area; propose no or only incidental surface parking area; and propose at least 85 percent lot coverageor downtown core zoning district,

Projects within the WDSP area are within a city designated Priority Development Area and automatically qualify for a 25% location credit. Up to a 50% location credit is applicable to projects located within one-quarter mile of the Amtrak train depot.

Special projects may qualify for up to 100% LID treatment reduction credit, based on the requirements and criteria for special projects specified in Section C.3.e.ii of the NPDES permit.

In addition to the C3 permit provision, all construction projects in Suisun City are regulated by the NPDES General Permit for Stormwater Discharges Associated with Construction Activity, which requires the preparation of a Storm Water Pollution Prevention Plan and filing of a Notice of Intent with the State Water Resources Control Board for all project that disturb an area of one acre or greater.

Storm Drainage Pumps
The City has four stations that drain the areas within and discharge at locations described below:
 Downtown/Main Street. This station is located underneath the area where Sacramento Street enters the public parking lot, adjacent to the marina. This drains the area from Solano Street, north to Hwy SR 12. School Street, west from Sacramento to the south, drains to another watershed. The Main Street pump station protects the northern section of the old downtown area and was just replaced this year as part of the downtown plaza. It now has a capacity of 8,500 GPM using two parallel submersible 193

5.2 Utility Services

5.2 Utility Services
November January 20162022October 2023 Page 5-19
pumps. The station is controlled by a PLC using a bubbler system for level control. The calculated runoff is 4,100 GPM.
 The Wildlife/Kellogg Street Pump Station. This station is located at the south end of Kellogg Street. It drains from Solano Street south, including the area above that drains down School Street. It pumps the water collected from the southern part of the old downtown area into the Suisun Slough. There is one main outlet into the Wildlife Channel, which is the School Street storm drain. The pump station and discharge line were replaced in 1997 with a submersible pump station, built next to the old station, and a new larger discharge line. The old pump, check valve, and MCC were removed and the old wet well and discharge line were left intact for possible future adaptation with a portable diesel pump for emergency use. The station includes a medium size detention basin allowing for some storage during short, high rainfall events.

The new station has a capacity of 4,600 GPM with one pump, 8,000 GPM with two pumps, and 9,900 GPM with three pumps.

Currently two pumps are installed with all piping and the MCC ready to accept a third pump. The calculated runoff is 7,800 GPM.
 The Whispering Bay/Mulberry Street Pump Station. This is located at the south end of the Whispering Bay Drainage Channel. It drains the area from Lotz Way and Main Street to Marina Boulevard, including all the residential streets within the area. There are multiple discharge outlets into the Whispering Bay Channel. The pump station has two independent propeller pumps with ultrasonic level controls. New discharge pipes and bar screens were installed in 1988. The estimated runoff is 15,700 GPM for a 6-hour event. He station was rebuilt in 2000 with capacity to exceed these flows. The station has a large detention basin allowing the required capacity to be lowered, if desired.  Heritage Park Subdivision/Chipman Lane Pump Station.

There is a pump station along Highway SR 12, about midway on Chipman Lane. This drains a large portion of the Heritage Park Subdivision. The Chipman Lane pump station collects storm water in the north-south area between Chipman Lane and the railroad tracks and pumps it under Highway SR 12 into a channel.

The station has three independent propeller pumps controlled by float switches, with a total capacity of 30,300 GPM. The estimated runoff is 8,300 GPM.

5.2.4 Solid Waste
The City of Suisun City contracts with Republic Services Solano Garbage to provide weekly collection of solid waste, yard waste, and recyclable material to the residents and businesses of Suisun City. As part of the statewide waste management and reduction policy, the California Integrated Waste Management Board (CIWMB) allocated the City of Suisun City with a disposal target of 4.9 pounds per person per day. In 194
Chapter 5 | Open Space + Public FacilitiesCivic and Services

2014, the City of Suisun City’s disposal rate was 2.6 pounds per person per day, considerably below the CIWMB target.

Suisun City has one recycling drop-off center located within the city boundaries. Recyclable material that is collected by Republic Services is sent to The Recyclery at Newby Island facility, located in Milpitas.

Solid waste collected from Suisun City is deposited at the Potrero Hills Landfill. In 2014, the landfill received 588,917 tons of solid waste, of which

2.3 percent was from Suisun City residents and businesses. The total capacity of the landfill is 55.865 million cubic yards. The landfill currently has a remaining capacity of approximately 33.815 million cubic yards. It is projected that the landfill will reach capacity in December 2045.

5.2.5 Gas and Electric
The Pacific Gas and Electric Company (PG&E) provides electricity and natural gas to the City. Public electrical energy for Solano County is generated outside the County and supplied via transmission lines. Major transmission line corridors traverse Solano County, serving the greater Bay Area. PG&E provides natural gas service to the area through both underground and aboveground transmission and distribution facilities.

New distribution facilities are typically constructed within easements on private property.

However, in some instances, new facilities are constructed within existing streets to increase capacity. Locations of distribution facilities generally depend on how and when an area develops. Specific Plan Area projects applicants and the City are required to involve PG&E in the development process to ensure that electricity and natural gas provision needs are incorporated into the development process.

5.2.6 Telecommunications
AT&T (formerly SBC), provides local telephone communication service for all of Solano County, including Suisun City and the Specific Plan Area.

Major telephone transmission lines traverse the region. These lines normally follow rights-of-way that parallel roadways and rail lines. AT&T also provides internet service in the area. Cable television service is provided through Comcast, Inc.

GUIDELINES

6.1 Introduction
This chapter establishes the development and design standards and design guidelines governing proposed development within the Waterfront District Specific Plan (WDSP) Area (Planning Specific Plan Area). When reviewing project plans, the reviewing body (Development Services Director, Planning Commission, or or City Council, or Development Services Director, as the case may be) shall refer to the WDSP development and design standards. and design guidelines. Where the WDSP is silent on an issue, the City will consult the General Plan and Zoning Code. If there is a conflict between the General Plan and the Zoning Code, the General Plan prevails.

A. Standards
Standards are identified by terms such as “shall,” “must,” “required,” or “prohibited.” Standards are specific and measurable regulations that are applied in the review of projects. Compliance with standards is required through the entitlement review process.

F. Guidelines
Guidelines are design principles that are generally expected to be followed unless the applicant can demonstrate that a deviation would still accomplish the intent of the guidelines to the same degree or better.

Refer to Chapter 7 of the Specific Plan for the administration of the Specific Plan, including the process for Site Plan and Architectural Review, Major and Minor Specific Plan Amendments, Variances, and Exceptions and the regulation of nonconforming uses and structures.

exterior improvements with the desired architectural character of the WDSP Area.

Development standards provide clear direction on the scale and location of new buildings constructed within the Specific Plan Area.

Design guidelines standards emphasize the creation of a sense of identity and orientation for pedestrians, residents, and visitors. This is accomplished by a variety of means, including through the scale, orientation, and design of the built environment; orientation and design of public spaces and landscaping; a grid street pattern; a visible hierarchy of streets; development of a comprehensive open space system; and other techniques.

Design guidelines standards for residential development apply to each of the residential Land Use Zones: Residential Low Density (RLD); Residential Medium Density (RMD); Residential High Density (RHD); and Historic Residential (HR). Please refer to Chapter 3 for a more detailed discussion of the Land Use Zones.

Design guidelines standards for commercial and mixed-use (residential and non-residential) development apply both based on the Land Use Zone of the proposed project. and also the Planning District within which the subject project site is located. Please see Chapter 2 for a discussion of the Planning Districts (and Figure 2-1).

Most of the Plan Area is built-outbuilt out. However, there are key opportunity sites, the development of which will be important to achieving the Specific Plan’s intent with respect to design. Figure 6-1, “Illustrative Site Concept Plan” shows how opportunity sites within the Specific Plan could be developed, consistent with the intent of this Plan.

Figure 6-1 provides illustrative concepts, but neither represents specific requirements or a formal endorsement by the City of the illustrative concepts.

6.2.1 Intent
Residential development and design standards and design guidelines focus on developing a traditional downtown setting that fosters community activities, social interaction, and a strong cohesive image for the Downtown Waterfront District. Design guidelines are intended tostandards will support fostermaintain the a pedestrian-oriented design environment, where the fundamental intent is to reduce the impact of the automobile vehicles by encouraging requiring narrower streets, smaller lots accessed by alleys and with opportunities for on-street parking and less off-street parking than allowed under conventional zoning standards. Old Town Suisun City is an inspiration for new residential development in the WDSP, with its smaller blocks and lots, grid pattern of streets, diverse architectural styles, and variety of housing types and sizes.

6.2.2 Residential Development Standards
Development standards for residential uses within the Specific Plan Planning Area are summarized in Table 6-1Table 6.1.

6.3.3 Main Street Mixed Use and Downtown Mixed
Use Zones in the Downtown Core
The following design standards and guidelines and development standards apply to the Main Street Mixed Use and Downtown Mixed Use Zones, particularly within the Downtown Core Planning District.

This District consists primarily of commercial buildings typically built up to the sidewalk edge, rectilinear in form, with large storefronts on the ground floor facade. Where residential structures exist on the west side of Main Street, the residential standards and guidelines in Section 6.1 shall govern. Refer to Chapter 4 for street and streetscape design guidelines standards for Main Street and other Downtown commercial and residential areas.

A. Building Height, Placement, and Setbacks

1. The height of new street-facing facades shallhould be greater than sixteen (16) feet but no more than fifty (50) feet, as measured from the sidewalk to the top of the cornice.

2. Along Main Street, building facades shall be a minimum of 16 feet in height and appear as a two (2) story building, if not two (2) stories or greater in height.

3. Where building heights differ between adjacent properties, the adjacent heights of major facade elements, such as storefronts, ground floors, upper floors, sill lines and strong horizontal features, such as belt courses and cornices shall be related.

4. Buildings and facades shall be constructed to the back of the sidewalk of the adjacent street(s). Only entries and flanking display windows may be recessed from the property line.

Doorways shouldshall be designed to focus on the street to create more activity along the sidewalk.

4.5. Businesses and buildings on Main Street shall face orand orient toward Main Street. Buildings on adjacent streets within the Downtown Core shall orient towards Harbor Plaza and/or the marina.

B. Building Form and Style

1. Like the historic buildings on Main Street, building forms shall be primarily rectilinear and parallel to existing nearby streets or buildings. Oblique, polygonal, and circular-shaped buildings are prohibited.

2. Architectural Unique character-defining architectural features of buildings that are eligible historical resources shall be maintained and respectedor replaced in-kind in any renovation or
remodeling work.

3. The scale of new construction shouldshall be harmonious with that of adjacent buildings. The scale of various design and

Downtown commercial structures are typically
rectilinear and built to the edge of the sidewalk.

Where building heights differ between
adjacent properties, the height of adjacent
ma
jor façade elements shall be related.

The scale of new infill construction shall be
harmonious with that of adjacent buildings of
historic interest.
209
Chapter 6 | Development + Design Standards + Design Guidelines

construction elements shouldshall be consistent with adjacent buildings of historic interest.

4.3. When a new building is proposed to replace a historic structure, key architectural elements of the original building shouldshall be used in the construction of the new building.

5.4. The architectural character of new construction and rehabilitation shall reflect the traditional building forms of historic Suisun City by containing design elements that procure historic elements within the commercial styles in a modern context. produce a similar visual image. Highly contemporary and articulated building forms are not permitted. “Wild West” themes typified by false front architecture, embellished with gingerbread-style detail, board- and- batten siding, and bright colors are not an appropriate or acceptable building motif.

C. Exterior Walls

1. Exterior walls shouldshall usually be designed with brick, wood, painted or architectural metal (such as cast iron and pressed metal with anodized finish or painted).

2. Except in limited amounts and in locations other than along Main Street, exterior wall materials not normally permitted include concrete, concrete block, stone veneer, stucco, granite, modern metal applications, large expanses of glass, tile, or plastic.

3. New storefronts along Main Street shouldshall approximate the rectangular shape, proportions, and architectural character of adjacent historic buildings of historic character. Storefronts with recessed entries are encouraged and shouldshall be divided into three bands with a base, middle, and top, including a transom

band, a band of display windows, and a small spandrel or paneled band under the display windows. One-story buildings shouldshall have a solid wall space above the storefront and a cornice, with or without a parapet. Two- story buildings shouldshall usually have a horizontal band and a second floor with windows and cornice. All of the above bands shouldshall align with those of adjacent buildings to the extent possible.

4. If provided, awnings shouldshall be regularly cleaned and maintained.

Awnings shall go through design review. Metal and glass awnings are discouragednot permitted. Mansard, fFree form, and geometric form awnings or other sidewalk covers are discouraged. Care shouldshall be taken in choosing the size, type, location, configuration, and color of awnings to ensure compatibility with the building’s architecture and the character of adjacent structures. Awnings or canopies that obscure transom windows or that are used primarily for signage rather than cover are not permitted.

5. Wooden balconies, canopies, and porches are traditional to some types of buildings and are encouragedProtrusions such as balconies, canopies, and porches, although encouraged, are subject to design review, where appropriate. The creation of such elements shouldshall be carefully considered to ensure compatibility with the style of historic structures along Main Street. Protrusions such as balconies, canopies, and porches mustay undergo architectural design review, as appropriate, to ensure compatibility with the style of historic structures along Main Street. Other important architectural features shouldshall not be obscured or destroyed in the building of these features.

6. Retail continuity along Main Street’s west side is essential.

Storefronts shouldshall be varied in design and architectural character, but continuous where possible along each block.

Storefronts shouldshall wrap around corners to create a sense of transparency and activity at intersections.

7. Buildings at key intersections (such as Main Street and Driftwood Drive) shouldshall be designed to “mark the corner” with such architectural features as a tower or a cupola. Such features may be erected to a greater height than fifty (50) feet, provided the design is in keeping with the overall architectural character of the structure and surroundings.

8. The backs and sides of buildings that are visible from public streets shouldshall incorporate window and door openings, where possible.

For new construction, backs and sides shouldshall be as carefully designed as front facades. On existing buildings, original openings shouldshall be restored or compatible new ones provided where feasible. Interesting details, awnings, painting, and landscaping should also be used to add visual interest to these areas.

Traditional design features, such as wooden
balconies, canopies, and porches are
encouraged.shall be used.

Buildings at key intersections, such as Main
Street and Driftwood Drive shallhould be
designed to mark the corner.

D. Windows and Doors

1. Except on narrow building fronts, windows shouldshall be organized in multiple bays, in coordination with ground-level storefronts. The directional expression of windows and doors shouldshall be vertical, although several vertical elements may be combined to form a horizontal opening.

2. Fenestration shouldshall be heavy wood rectilinear assemblies.

Metal window assemblies or metal window frames are discouraged.

Fenestration shouldshall be well proportioned and compatible with the dimensions of a given wall.

3. Glass in windows, doors, and transoms shouldshall primarily be kept clear. Plastic materials shouldshall not be used in place of glass.

4. Upper floor facades shouldshall be composed as solid surfaces with punched openings for individual windows or discrete sets of windows. The openings may be highlighted with special treatment at the head, sill, and/or sides, such as special brick coursing, arched heads, or other accents.

5. Large areas of blank wall with few openings or enriching details shouldshall be avoided on street facades. New and substantially rehabilitated buildings shouldshall have wall to window area ratios and proportions that are similar to the traditional Downtown buildings. For minor rehabilitated buildings, existing window openings, which have been boarded up, stuccoed, or painted over shouldshall be restored and reglazed.

6. Original or existing storefront areas and window openings shouldshall not be filled in or covered up from either the interior or exterior of the building. Where buildings with retail storefront display areas have been converted to non-retail uses, such as offices, the storefront glazing shouldshall not be covered over or permanently obscured. Removable interior window coverings may be used to provide some degree of privacy, but visual contact with the street shouldshall be maintained to the maximum extent feasible.

7. At least 50 percent of the ground floor shall include windows, door, glazing that is transparent and allows views of the interior

6.8. At least one main entrance shall be directly from the street.

E. Roofs

6.3 Commercial Development + Design Standards + Design Guidelines November January 2016 2022October 2023 Page 6-19

2. Pitched roofs shouldshall usually be include dark asphalt shingles. Roofing materials not normally allowed include weathered wood shingles, concrete, plastic tile, or fabric.

2.3. Rooftops with mechanical equipment shouldshall be concealed.

F. Color

1. Choice for building exteriors may express individual taste, but shouldshall always contribute to the historical character of the area. Exterior colors shouldshall harmonize with other colors on the same building and on the streetscape.

2. Exterior colors shouldshall complement the colors of neighboring buildings or storefronts and shouldshall be selected to be mutually supportive and beneficialadd to the overall character of the streetscape.

3. Where brick has been painted, repainting is appropriate. Where brick was unpainted and remains unpainted, use of paint on the exterior is prohibited.

4. Colors for building walls and storefronts shouldshall be uniform for a shop, which occupy multiple storefront buildings.

5. The use of different colors to mark individual shops within a building can be visually disruptive and obscure the overall composition of the facade. Where existing buildings have been painted in this manner, they shouldshall be repainted
complementing colors when rehabilitation or change in tenancy occurs.

6. A range of compleimentary colors may be selected for signs and awnings of individual shops within the same building. The sign and awning color of individual businesses shouldshall be coordinated wherever possible. Patterned or multi-colored awnings shouldshall be used with care and in consideration of the color(s) of adjacent awnings.

6.3.4 Historic Limited Commercial Zone
The Historic Limited Commercial Land Use Zone occurs in both the Downtown Core Planning District and Historic Suisun Planning District.

The buildings that front on Main Street between Morgan Street and Cordelia Street and the areas within the HLC zone are predominantly residential in design and character. These structures are expected to convert to retail or limited commercial uses over time. The following sections address these “transitional” buildings and provide standards and guidelines for their renovation for commercial use. These guidelinesStandards also apply to the design of new commercial structures so that residential elements are incorporated and are compatible with the existing structures in which they adjoin.

Complementary colors shallould be selected
for signs and awnings of individual shops
within the same building.

Additions to existing structures shall be a
height and scale that does not overwhelm
the original building.
215
Chapter 6 | Development + Design Standards + Design Guidelines

A. Building Height, Placement, and Setbacks

1. The maximum height of any new building or addition to an existing building shall be thirty-five (35) feet. The maximum height limitation matches that specified for the adjacent residential district. ThisIt will allow for an appropriate transition in scale between commercial and residential zones.

2. Additions to existing structures shall be not exceed the height of the original building by more than 80 percent and shall not exceed the square footage of the original building by more than 50 percentof a height and scale which does not overwhelm that of the original building.

3. Building setbacks shouldshall be provided from all property lines. The front yard and side setback from the street
shouldshall approximate that of adjacent residential buildings on the block. Rear and side setbacks shouldshall be similar to those provided for existing residential buildings, with greater setbacks provided for new structures or additions of significantly greater height or scale.

Building setbacks from the street will help to maintain a consistent street wall and signal the transition from the commercial area to the adjacent residential area. Side and rear setbacks can provide buffer zones to protect the privacy of adjacent residential areas.

4. Setback areas shall be adequately landscaped to provide a residential character to the street and to form green buffers between buildings. The presence of trees and planting around buildings is typical of residential areas and will provide an appropriate transition between them and the commercial area.

B. Building Form and Composition

1. Unique architectural features and the overall residential quality and appearance of a structure shouldshall be maintained and respected. Major form-giving elements to be retained include pitched rooflines, projecting or recessed entry porches, dormers, and bay windows. Important features and details may include multi-paned windows set in wood frames, overhanging eaves, decorative brackets and balustradesbalustrades, and substantially designed porch bases and steps.

The conversion of a residential structure to commercial use shouldshall not destroy the residential character of the building.

Where modifications are necessary to improve access, they shouldshall be done in a manner that is least disruptive of the original building fabric. Closing or filling porches or window

Unique architectural features and the
residential quality and appearance of
structures should be maintained.

Conversion of a residential structure to a
commercial use should not destroy the
character of the building.

New larger buildings should use smaller-scaled
elements that approximate the scale or form
of adjacent residential development.

Setback areas shall be adequately
landscaped to provide a residential
character and green buffer to the street.

openings destroys the building's character and is
inappropriateprohibited.

2. New construction and additions to existing buildings shouldshall utilize the major residential form-giving elements described above.

3. Roof forms shouldshall be expressed rather than concealed behind parapets or false fronts. Appropriate forms are those typically used for residential development in and adjacent to the area. These include hip, gablegable, and shed forms with projecting eaves. Roof forms for building additions shouldshall be consistent with those of the original structures.

4. Building massing shouldshall relate to the scale of surrounding residential structures. Where a new building will be significantly larger than surrounding structures, it shouldshall be composed of smaller elements that approximate the scale or form of the existing, adjacent residential structures.

In order to avoid changes in scale that would overwhelm adjoining residential structures, new buildings shouldshall use smaller-scaled elements as building blocks. Devices, such as partial or full setback upper floors, building projections or recesses, and changing or articulated roof forms help to reduce the apparent mass of a building.

C. Material Finishes and Colors

1. Exterior wall materials shouldshall be limited to those commonly used for residential buildings, including wood siding, and brick.

2. Additions to existing buildings shouldshall be finished in the same material as the original structure. Complementary
materials, such as wood shakes with wood siding or brick with stucco may be used for architectural accents or special details.

3. Existing window openings and multi-paned windows shouldshall be retained. Large expenses expanses of glass shouldshall be avoided in building additions and new construction in favor of individual window openings with multi-paned windows or
multiple window units.

4. Window frames shall be of painted wood, metal, dark anodized aluminum, or in the case of a renovation, a material and finish which matches the existing original window frames.

5. Metal window grilles or other exterior devices, which imply security problems, are discouraged.

Visible security devices detract from the area's image. Security problems shouldshall be addressed in less visible ways, such as internal alarm systems, which will not detract from the visual image of the area.

Exterior wall materials shallould use
traditional residential building materials,
such as wood siding, stone, and brick.

Use of fabric awnings is encouragedshall
be used, where appropriate to the
building design
217
Chapter 6 | Development + Design Standards + Design Guidelines

6. Appropriate paint colors for building wall surfaces include white or light, neutral pastels similar to those called for in other commercial zones, medium toned natural finishes for brick.

Where wood siding or shakes are used, darker stains or painted finishes may also be appropriate. Trim elements and details may be painted to match the building wall or in a contrasting color.

7. The use of fabricFabric awnings is encouragedshall be used where appropriate to the design of the building.If used, Aawnings shouldshall be placed to avoid obscuring architectural features or overwhelming the scale of the building. Awnings may be placed over windows or entries but must be attached
directly to the building and be self-supporting. Extended sidewalk canopies are inappropriate.prohibited.

6.3.5 Commercial/Office/Residential and Waterfront
Commercial Land Zones
The Commercial/Office/Residential and Waterfront Commercial Land Use Zones occur within both the Downtown Core and the Southern Waterfront Planning Districts. These areas adjacent to the waterfront are related to the historic Downtown, yet have very different characteristics.

Proposed uses within these parcels are intended to build upon and enhance the character and function begun on these sites. The following design guidelines address the unique character of these two distinct opportunity areas.

C/O/R Zone Design Guidelines
All commercial buildings should have facades built to the back of the sidewalk, in order to maintain an active and interesting edge for window shoppers, strollers, and passersby.

Residential setbacks, where applicable, should be consistent with residential development in the Victorian Harbor neighborhood.

In keeping with the historic character, the linear frontage of new buildings along Main Street south of Driftwood Drive should not exceed fifty (50) feet. Commercial or mixed-use development north of Driftwood Drive may be larger. The design of the building should still emphasize the vertical appearance of smaller increments of building frontage that preserves the pedestrian quality present along Main Street.

New development and buildings should be designed to maximize waterfront views and access from common area spaces, as well as front onto the major surrounding streets, including Main Street, Lotz Way, and Civic Center Boulevard.

A. Flexibility in the application of these design guidelines can be attained through the PUD process.Waterfront
Commercial Zone Design GuidelinesStandards
New development in this area shall be guided by the design guidelines standards in Section 6.3.4, addressing the Historic Limited Commercial zone, and the following additional guidelinesstandards.

Hotel/Motel 1 space per room
Commercial or Public Use
Refer to parking requirement in the City Zoning Code, except that the minimum off-street parking spaces shall not be greater than 1 space per 300 gross square feet. Proposed buildings of less than 5,000 square feet with adjacent on-street parking shall not be required to provide any off-street parking..

Notes:
* At the discretion of the Cit y, parking within the one-quarter mile radius of the Suisun City train 229
Chapter 6 | Development + Design Standards + Design Guidelines

 At the discretion of the City, pParking within the one-quarter mile radius of the Suisun City train depot may will be waived. 

B. Parking in Commercial and Mixed Use Zones
Generally, parking required for existing and proposed new uses within most of the commercial and mixed use zones will be met by a combination of public and private on- and off-street public parking facilities, associated with specific uses and properties. Public parking is provided on Main Street, in and around the marina and Harbor Plaza.

Because of the variety of uses envisioned in the Planning Specific Plan Area, peak demand periods will vary, allowing opportunities for shared facilities by more than one use or property.

1. Required parking for all existing uses in existence at the date of adoption of this Specific Plan can beare satisfied by existing private on- site facilities and public parking on Main Street and Harbor Plaza.

2. New uses established after the adoption of this Specific Plan shall be required to meet parking standards with either on-site parking, on-street parking, or a combination of on-site and on- street parking, consistent with the requirement of this Specific Plan. Off-site parking may be usedby first providing as much of the requirement on-site as possible, while still keeping with the desired character of development. Off-site parking spaces may also address this requirement, where it is demonstrated that such spaces are available during the peak demand periods for the particular use in question (see requirements for shared parking below).

C. Fees In-Lieu of Required Parking
Where a use cannot satisfy its parking requirement through either on- site or available shared parking,, when available, the remaining requirement may be satisfied by payment of a fee in lieu of actual development of the required parking. Said fee is to be set by resolution of the City Council and shall be equal to the estimated cost of land acquisition and development of one off-street surface parking space.

This fee will be charged for each of the required parking spaces, which cannot otherwise be provided for the proposed use.
depot may be waived.
**1. For developments containing five or more units, up to thirty-five percent (35%) of the required uncovered spaces may be compact car spaces.
*** On-street parking spaces adjacent to the property street frontage may be used to satisfy required off-street parking requirements.

An exception reducing the required parking spaces to less than the above standards may be approved by the Administrator or the Planning Commission, as the case may be, provided provided the following findings are made:

1. The actual parking demand for the use in question will be less than the above standards.

2. The proposed use will not generate additional long termlong- term parking -demand without expansion of the building area occupied..

3. If a new building or structure, the probable long-term occupancy , based on its design will not generate additional parking demand.

The applicant will be responsible for the collection and submittal of survey or other data sufficient for the above findings to be made. Refer to Section 7.6.5 of the Specific Plan for the procedures for exceptions.

E. Shared Parking Requirements
Parking spaces may be shared by more than one use when operations are not normally conducted during the same hours or when hours of peak use vary. Requests for the use of shared parking may be considered within the project review process as a strategy to meet required off-street parking requirements and must meet the following conditions:

1. The applicant must satisfactorily demonstrate that substantial conflict shall not exist in the principal hours or periods of peak demand for the uses for which shared spaces are proposed.

2. Parking spaces designated for shared use shall not be located fuarther than eight hundred (800) feet from any structure or use served, unless otherwise approved.

3. A written Agreement shall be drawn to the satisfaction of the City attorney and executed by all parties concerned ensuring the continued availability of the number of stalls designated for shared use.

4. The number of existing parking stalls which may be credited against the requirements for proposed structures or uses shall not exceed the number of stalls reasonably anticipated to be available during differing hours of peak demand.

5. In determining the availability of parking spaces for shared use; peak and off-peak demand shall be calculated using the
standards and methods described in the City’s Zoning Code, Section 18.52.04042.090 or other approach approved by the City.
231
Chapter 6 | Development + Design Standards + Design Guidelines

6. Total required on-site parking spaces for mixed-use
developments shall be determined by computing the parking requirements for each of the above time periods. The largest total demand for the four periods shall be the required number of spaces to be provided.

F. Parking in Residential Front Yards
No portion of any front yard other than a paved driveway shall be utilized for parking or storing of any motor vehicle, recreational vehicle, boat, trailer, or camper.

G. Parking Design
Dimensions, geometrics, and landscaping of parking areas shall be as specified by the City’s Zoning Code, unless otherwise specified in this section.

1. Where on-site parking is utilizedutilized, it shall be provided in a location, which is least visually disruptive. The preferred location of parking lots is at the rear of the property or screened from view by the building. An alternative location would be at the side of the building. Parking shall not be sited in the setback area between the street and the building line, where such setback exists. Parking located in front of buildings, adjacent to the public right-of-way, shouldshall be screened with vegetation and/or fencing. Access drives shouldshall be located besides the building or at the rear of the building on corner lots.

2. Parking lots shouldshall be adequately landscaped within and at the perimeter, adjacent to abutting streets and buildings. Parking areas, which abut residential uses or zones, shouldshall be screened with a dense hedge and/or a fence. Lighting shouldshall be directed away from residences.

In addition to these requirements, major amendments shall require a public hearing and notification, similar in nature to the process for amendments, addressed in the City Zoning Code, Chapter 18.7482, “Amendments.”

7.2.2 Application
Application for a Specific Plan Amendment shall be filed with the Planning Division upon such forms and accompanied by such data as may be prescribed by the Planning Division, so as to ensure the fullest practicable presentation of the facts for the permanent record. A fee set by resolution of the City Council shall accompany each application. A Specific Plan Amendment may be initiated by the City.

7.2.3 Scope of Amendment
The Administrator will be responsible for determining “major” amendments as opposed to “minor” amendments to the Plan and its Standards. “Major” amendments shall be processed as outlined above through the Planning Commission and City Council. Among the items which would be considered major are:
 Introduction of a new type of land use not discussed in the Specific Plan or City Zoning Code that would affect one or more property owners.
 Major changes to the layout of land uses (affecting one acre of land or more) or other changes, which may significantly affect a planning concept spelled out in this Specific Plan.
 Major changes to the proposed street system that would significantly alter land use or circulation concepts described in this Specific Plan.
 Changes or additions to design standards, which could significantly change the stated intent of this Specific Plan.
 Any change to the Specific Plan which could create new environmental impacts or substantially increase environmental 234

7.2 Specific Plan Adoption
November January 20162022October 2023 Page 7-3
impacts beyond that reported in the Specific Plan Consistency Analysis.

Minor amendments shall be decided by the Administrator, subject to appeal to the Planning Commission. Minor amendments include:
 A proposed land use not identified in the Specific Plan or City Zoning Code that is substantially similar to a permitted use with respect to characteristics, intensity, and compatibility, according to the requirements of section 7.4.3 of this chapter. Minor changes to the land use diagram and/or alignment of streets that maintain the general pattern of permitted land uses and circulation and that are consistent with the vision, goals, and policies of the Specific Plan.  A change to the development and design standards or design guidelines that does not significantly change the physical characteristics or purpose and intent of the Specific Plan and is determined by the Administrator as minor or requests for an adjustment that is10 percent or less of quantifiable or measureable measurable standards contained in the WDSP.
 Changes not expected to substantially increase any environmental impact beyond the levels identified in the Specific Plan Consistency Analysis.
 Minor text revisions required to clarify the intent of the Specific Plan, remove ambiguities, or maintain consistency with other adopted City planning and policy documents.
 Other modifications of a similar nature to those listed above, which are deemed minor by the Administrator and in keeping with the purpose and intent of the Specific Plan.

7.2.4 Findings
In considering any amendment to the Specific Plan the appropriate decision-making body shall make the following findings:
 The proposed amendment would benefit the Specific Plan Area.  The proposed amendment would conform to the General Plan or would be considered in conjunction with an amendment of the General Plan.
 The proposed amendment would not adversely affect adjacent properties.
 If use specific, the subject property could be properly served by public facilities and services.

7.2.5 Amendment Procedures
The process for Major Amendments to the WDSP shall be the same as the process to amend the Zoning Code as described in Chapter 18.74 235

Waterfront District Specific Plan
October 2023 Page 1-1
CHAPTER 1 | INTRODUCTION

1.1 Background/ Content
The Waterfront District Specific Plan (WDSP), previously called the Downtown Waterfront Specific Plan, was adopted in 1983 and comprehensively amended in 1999. The creation of a specific plan for the WDSP Area (Specific Plan Area) was proposed as an implementation action in the 1979 Suisun City General Plan, which called for special treatment of the historic downtown and waterfront through the preparation and adoption of a Specific Plan for Old Town and the waterfront. Since that time, many actions identified in the Specific Plan have been implemented.

In 2015, the City of Suisun City (City) adopted a comprehensive revision to the General Plan. The 2035 General Plan provides an updated set of policy guidelines for the overall amount, character, and location of urban development, as well as preservation and natural resource conservation, economic development, transportation, safety, public facilities and services, and housing.

In 2008, the Association of Bay Area Governments (ABAG) approved the Specific Plan Area as a planned priority development area (PDA) under the PDA grant program administered by the Metropolitan Transportation Commission (MTC), ABAG, and other regional agencies. PDAs are opportunity areas in the Bay Area, locally adopted by cities or counties to facilitate growth and infill development near fixed transportation facilities.

PDAs are designed to provide residents with housing, community amenities, and services in a pedestrian-friendly environment.

In 2014, the City received grant funding from the Solano Transportation Authority to prepare an update to the WDSP. This update addressed the Specific Plan Area, which expanded on the previous WDSP boundaries to include the properties north of State Highway 12 (SR 12) – at the northwest corner of Marina Boulevard and SR 12 and the properties between Main Street and SR 12, including the “Denverton Curve” property in the northwest of the Specific Plan Area (Figure 1-1). The expanded Specific Plan Area boundary allows the City to better leverage the assets of the Suisun-Fairfield train depot to encourage infill development and establish a gateway entrance into the Specific Plan Area on both sides of SR 12. This update also addressed 255
Chapter 1 | Introduction

current market conditions, the current regulatory environment, and recent City policy updates, and was adopted in November of 2016.

In 2020, the City received another grant – this time from the State of California, through a program administered by the California Department of Housing and Community Development. The purpose of the State’s “SB 2” planning grant program is to streamline housing approvals and accelerate housing production. The City used the SB 2 grant funds to prepare this update to the 2016 WDSP policies and development standards to better facilitate housing development, particularly in areas with high-quality transit and within walking distance of employment, services, and entertainment.

1.2 Location
Suisun City is in central Solano County, midway between the cities of Sacramento and San Francisco (Figure 1-1). The City is bounded by the city of Fairfield to the north and west, Travis Air Force Base to the east, and Suisun Marsh to the south. Suisun City is adjacent to and bisected by State SR 12, a vital trucking route, and is approximately two miles east of Interstate 80.

Suisun Slough, a major tidal waterway, connects Suisun City to Suisun Bay and provides access to water sports, recreation, boating, fishing, and bird watching. The adjoining Suisun Marsh is the largest brackish estuary west of the Mississippi River and borders the south and east sides of the Specific Plan Area. The Specific Plan Area straddles both sides of SR 12 and is located southeast of the Union Pacific Railway tracks and west of the Suisun Channel and Marina Boulevard (Figure 1-2).

1.3 Specific Plan Vision
October 2023 Page 1-5

1.3 Specific Plan Visio n
The Specific Plan implements the General Plan’s direction to:
▪ Strategically develop vacant, underutilized, and infill land throughout the City and especially in the downtown.
▪ Strategically develop the Priority Development Area to provide convenient, attractive housing, shopping, services, and employment in the downtown neighborhood.
▪ Develop the downtown as the social and cultural heart of the community.
▪ Promote a vibrant downtown that provides both daytime and nighttime activities to attract visitors.
▪ Foster transit-oriented development around the train station, including higher density housing and mixed-use development. ▪ Provide convenient linkages from the train station and other regional connectors to bring patrons to the downtown.
▪ Provide transportation alternatives to the automobile, especially capitalizing on the location of the train station.
▪ Ensure safe and efficient walking, biking, driving, and parking in the downtown.

The Waterfront District is comprised of three principal character areas (Figure 1-3), intended to function as their names imply, including the:
▪ “Shopping, Entertainment, Culture, and Transit-Supportive Housing” area, comprising the commercial, mixed-use, and civic portions of the Downtown Waterfront District on both sides of SR 12 and the Suisun Channel;
▪ “Historic Old Town” area, adjacent to the railroad tracks and comprising the older historic residential, commercial businesses, and main street retail core of the Downtown Waterfront District; and ▪ “Neighborhoods,” residential neighborhood areas with access and frontage to the waterfront on the eastern and southern portions of the District.

These character areas and the vision statements that follow in this section establish the overarching vision and plan concepts for the Downtown Waterfront District. The planned improvements, development standards, and design standards in this Specific Plan are intended to enhance the function of these character areas as the Specific Plan Area develops. 259

1.3 Specific Plan Vision
October 2023 Page 1-7
The WDSP is to be guided by the vision statements identified below in italicized text and followed by a description of the characteristics and key concepts for implementation of the WDSP. The vision and plan concepts are based in part on earlier iterations of the Specific Plan, but with updates to reflect input from the community and City leaders, the regulatory environment, existing market conditions and market trends.

1. Suisun City’s Historic Waterfront District is a unique waterfront community with a marina; an “Old Town,” composed of a
traditional Downtown commercial main street and historic residential neighborhoods; a marina supporting boating and waterfront recreational activities; a civic center area; and uniquely designed residential neighborhoods, including Whispering Bay and Victorian Harbor east of the marina, and Delta Cove and “Historic Old Town” west of the marina.

The WDSP Area draws on the area’s unique mix of characteristics–a recreational waterfront, a historic main street, well-preserved residential historic architecture, established neighborhoods, direct highway access, regional commuter rail service, a rich natural environment, and a location that is attractive for development that complements the unique character of the area.

2. Suisun City’s Historic Waterfront District is a pleasant place to live and, at the same time, a local and regional destination for dining, shopping, entertainment, hospitality, tourism, and recreation.

Downtown is a place that attracts new residents, jobs, businesses, diners, shoppers, and visitors.

Significantly increased residential and economic development in the region has created market support for transit-supportive housing, dining, entertainment, specialty retail, and marine-related services.

Employment growth in Fairfield, Vacaville, and Vallejo, along with high housing prices in Bay Area employment centers, have increased demand for housing in Solano County.

Suisun City, which was once difficult to access from employment centers, is now within an acceptable commute distance, including commuting by rail, to the Bay Area and Sacramento. Intercity rail service along the Capitol Corridor enhances that position and will continue to increase demand for housing near the Suisun City train depot.

The City’s location on the San Francisco Bay Area Water Trail makes it a unique destination for visitors exploring the waterways of the San Francisco Bay by boat or sailcraft.

A unique waterfront community with a

A local and regional destination for
shopping, entertainment, hospitality,

Chapter 1 | Introduction

3. The City should market the Waterfront District as a destination on the San Francisco Bay Area Water Trail and continue to focus on maximizing waterfront access on the Suisun Channel–its major and central feature. Priority should also be given to improving visibility and public access to the train depot, another key asset for bringing guests in town to enjoy the amenities of Suisun City’s Waterfront District.

The waterfront is an extraordinary amenity offering both an urban waterfront and an unusual in-town wetlands habitat. The waterfront creates daily activity along its edge; enriches the experience of the area with its seasonal and tidal changes, wildlife, open space, and vistas; and serves as a theme for community activities and events. There are few towns in California with such an extensive and multifaceted waterfront.

The Waterfront District landscape needs to celebrate and accentuate its relationship to the water’s edge by emphasizing public access and views along both sides of the Channel and Whispering Bay.

4. The waterfront should maintain its extraordinary mix of natural wetlands and urban edge.

The Suisun Channel is the gateway to the large open waterways and wetlands of the California Delta and San Francisco Bay and is a unique stop on the Bay Area Water Trail. The channel is unique in its mix of hard and soft edges, allowing for a rare blend of commercial and marine-related activities along one side of the Channel, and expansive wildlife habitats along the other side. Pedestrians walking along the Channel are able to experience a variety of different environments within close proximity of each other. These relationships need to be emphasized and enhanced. Important to capitalizing on this strength is ensuring all areas of the waterfront are provided inviting and attractive pedestrian access.

5. The historic Suisun City train depot on the north end of Main Street should serve as a transit gateway into the Waterfront District.

The historic train depot serves as a multimodal transportation hub for intercity rail service and local and regional bus service. The station is at the northern terminus of Main Street, within the Waterfront District and is near the Central County Bikeway (regional Class I bike trail), connecting the downtowns of Suisun City and Fairfield. While there are directional signs to the train depot, the station facility is otherwise easy to miss as it is located in a modest structure tucked behind on-street parking, a landscaped plaza with tall trees, and SR 12. Iconic signage, art, and streetscape/landscape enhancements should be added to emphasize the importance of this key destination and historic facility within the community.

October 2023 Page 1-9

6. The circulation system should be enhanced to support safer and more convenient access between homes and destinations in Suisun City and between the Waterfront District and Downtown Fairfield–emphasizing pedestrians, cyclists, transit users, and motorists.

The existing street system has three dead-ends – Main Street, Civic Center Boulevard, and Marina Boulevard. Lotz Way will serve as a major west-east arterial that links Main Street, Civic Center Boulevard, and Marina Boulevard. Main Street can be linked to Civic Center Boulevard via Driftwood Drive, along a multi-use path connection and plaza.

New and improved roadway, bicycle, and pedestrian connections between Downtown Fairfield and the Downtown Waterfront District, in addition to new transit-oriented housing development Downtown, will help to expand the market for existing and future Suisun City businesses, supporting further commercial development in the Waterfront District.

7. The Waterfront District needs a cohesive open space system that enhances the pedestrian experience and supports community access.

Extended out from the waterfront should be a system of paths, tree- lined sidewalks, and promenades that clearly and visibly link to the visitor amenities (dining, lodging, and entertainment) in the Waterfront District and to the neighborhood parks and open spaces throughout the Specific Plan Area. Streets should be designed to provide direct vistas and bike and pedestrian access to the Suisun Channel, Whispering Bay, and neighborhood parks, wherever possible.

8. Gateways to the Waterfront District, including from SR 12, Railroad Avenue, the marina, and the train depot should be enhanced to ensure a positive first visual impression.

The grade separation of SR 12 through the Specific Plan Area, existing building development, and underutilized land adjacent to the highway serve as barriers to visual access of the Waterfront District and its beautiful marina, historic Main Street, and train depot. Iconic signage, landscaped gateways, vertical monuments, wall art, and visually compatible infill development along both sides of the highway and rail tracks should mark the entrances to the Waterfront District.

Similarly, vertical monuments, public art, and landscaping should be used to activate the entrances along the marina and boat launch areas.

The property at the northwest corner of SR 12 and Marina Boulevard and the property at the southwest corner of Railroad Avenue and Marina Boulevard should incorporate vertical landscape elements and vertical architectural design details to demark entry to the Specific Plan Suisun City’s Historic Downtown
Waterfront District has...

Safe and convenient circulation and
access by foot, bike, or transit; and
connections to Downtown Fairfield.

A landscaped gateway, vertical

Chapter 1 | Introduction

Area at Marina Boulevard and Main Street, traveling westbound on SR 12, and Railroad Avenue traveling southbound on Marina Boulevard.

These features should be designed to market and draw visitors into the Waterfront District.

9. Development adjacent to the historic residential area should be compatible in scale and architectural themes.

The historic commercial and residential structures along Main Street and the Old Town residential area help to establish the unique character of the Waterfront District. To preserve this legacy, architectural compatibility of new development, gateways, and green space are key themes addressed in the Design Standards of this Specific Plan.

10. Where feasible and consistent with building codes, existing buildings should be re-purposed with more economically viable uses that contribute to the vibrancy of the Waterfront District.

Many older structures in the Waterfront District have architectural elements that contribute to the historic character of the street or neighborhood. Those elements and structures should be preserved, to the extent feasible, and be repurposed or renovated to contribute to the unique identity of the Waterfront District and Old Town.

1.5 Specific Plan Goals
October 2023 Page 1-11

1.4 Specific Plan Goals
The following goals were initiated in the 1983 Specific Plan, included in the 1991, 1999, and 2016 amendments, and are being revised in this update to the WDSP.

1. Strengthen the economic viability of the historic Old Town, waterfront, adjacent areas, and the city as a whole.

This is the primary goal of the Specific Plan. A variety of implementation techniques will be required to achieve this goal.

Economic viability is achieved through the collective efforts of private sector investment, public planning, and ultimately by consumer demand.

The waterfront is a unique resource and attraction in central Solano County and, along with the regional commuter service at the train depot, represents one of the best economic development assets in the City. The community must capitalize upon this critical opportunity by ensuring that development in the Waterfront District accommodates the highest possible level of residential, visitor, and commercial activity.

2. Facilitate housing development Downtown.

The City has a tremendous opportunity to expand housing opportunities for existing and future residents Downtown, while also creating many other co-benefits. Housing can be more affordable by design, allowing households that might have been previously priced out to relocate to Suisun City. Housing that is close to jobs, services, parks, and other destinations can allow more residents to meet their daily needs without the need for a car, freeing up disposable income that can make housing more affordable or that can be spent at local businesses.

Establishing transit-supportive housing options in Suisun City, but in the Specific Plan Area in particular, would expand the range of housing options, making the City more competitive for attracting employers, many of whom are interested in a diverse and affordable local housing stock. Placing more housing Downtown means more customers for existing and future businesses. Facilitating housing development in areas near transit and destinations will reduce the need for vehicular trips and associated transportation noise, air pollutant emissions, and greenhouse gas emissions, and improves public health by allowing more residents to build physical activity into their daily routines.

3. Preserve and enhance the area’s historic character.

Preserving and enhancing the historic character of the Waterfront District is one of the central themes of the development policies of this Specific Plan. Achieving this goal requires that the water-related early California heritage of Downtown and the residential areas west of Main Street be used to attract investments and consumers to the area. 265
Chapter 1 | Introduction

California heritage of Downtown and the residential areas west of Main Street be used to attract investments and consumers to the area.

Visitors are naturally attracted to areas of historic significance. Reviving the original design and character of older buildings and historic sites is an essential supplement to the waterfront for attracting consumers from the surrounding area. New development or renovations in Old Town should anticipate and support incremental changes in Downtown, while not losing sight of the features that contribute to its historic character and identity, as addressed in more detail in Chapter 6, “Design Standards” of this Specific Plan.

4. Facilitate appropriate water-oriented and economic uses of the Suisun Channel and adjacent land areas.

In addition to its historic character, Suisun City's other major natural asset is the Channel and the access it provides to San Francisco Bay and Delta waterways, especially as a designated destination on the San Francisco Bay Area Water Trail. Suisun City was founded because these waterways provided a means of transportation from agricultural production to consumer markets in San Francisco. The waterways continue as a significant recreational and commercial resource. To facilitate use of the Channel, marina and shoreline improvements and convenient public access must be provided and maintained. Permanent dredge disposal sites must be maintained and managed to ensure the continued viability of the waterfront.

5. Protect and enhance natural open space and recreational amenities of the Suisun Channel and adjoining areas.

The Suisun Channel and adjoining marsh areas are environmentally sensitive. Development adjacent to these areas must recognize this sensitivity and be designed and located in a way that does not degrade this valuable resource, especially considering climate change. Preserving the environmental integrity of the Channel and marshes will enhance wildlife habitat and contribute to the area’s attractiveness for both living and working in.

6. Foster participation between the public and private sector in carrying out a program of revitalization for the Specific Plan Area.

Revitalization and economic development will not occur by the efforts of either the public or private sectors acting alone. The private sector relies on the coordination and assistance of government to ensure that investment in individual projects makes economic sense in areas where development costs are too great to bear without such assistance. The public sector relies on private investment to provide the economic activity necessary to carry out needed improvements. Public and 266

private entities can collaborate on a revitalized, vibrant, and healthy environment for the Specific Plan Area.

REGULATING PLANS

2.1 Existing Uses
The City of Suisun City is bisected by State Highway 12 (SR 12). North of SR 12 are residential areas and neighborhood-serving uses. The historic “Old Town,” mixed-use waterfront, and marshland are south and west of the highway. The Waterfront District Specific Plan (WDSP) Area (Specific Plan Area) is centered on the City’s Historic Downtown Waterfront and Old Town areas, located at the head of the Suisun Channel (Figure 2-1).

The Specific Plan Area is a mix of retail and services along Main Street, the City’s civic center, marina and water-oriented recreation along the Suisun Channel, industrial uses and the Suisun-Fairfield Train Depot along the Union Pacific railroad tracks, a historic residential core west of Main Street, and newer traditionally designed residential neighborhoods along the waterfront and east of the channel. The Suisun Slough and marsh area borders the Specific Plan Area to the south and provides access to the natural and scenic resources and recreational activities along the waterways of the Delta and San Francisco Bay. The Specific Plan Area also includes a neighborhood shopping center, a mobile home park, and vacant properties north of SR 12.

SR 12 provides access into the Specific Plan Area from an off-ramp at Civic Center Boulevard from eastbound SR 12, an off-ramp at Main Street from westbound SR 12, and an at-grade intersection at Marina Boulevard. The main access point into the Specific Plan Area from the southwest is from Cordelia Road, which becomes Cordelia Street as it enters the city. The Suisun-Fairfield Train Depot, recreational waterfront, and regional bike trails provide access to the Waterfront District from the city of Fairfield, the eastern and northern parts of Suisun City, and the broader region.

2.1.1 Plan ning Districts
Eight planning districts are identified for the Specific Plan Area (Figure 2-1). Figure 2-2 shows a general depiction of existing uses in the Specific Plan Area.

District 3, Downtown Commercial Core
District 3 consists of the properties immediately surrounding the Suisun Channel, including the marina area, Main Street and Harbor Plaza to the west, One Harbor Center to the north, and the Civic Center area to the east. Main Street, from SR 12 south to Morgan Street, serves as the spine and focal point for the Downtown Commercial Core. Paralleling the Suisun Channel, Main Street provides a reflection back to the historic past when Suisun City was a major shipping port. Along this street are one- and two-story commercial buildings, many of which have both historic and architectural value.

At the north end of the Suisun Channel is the site of the former Sheldon Oil facilities, which has been redeveloped with an informal open space green and plaza areas, referred to as Sheldon Plaza. Between Main and Kellogg Streets and the Suisun Channel is a mix of commercial and light industrial uses, some related to the marina uses along the waterfront.

District 8, Civic Center / Whispering Bay Waterfront
District 8 includes the civic center area, anchored by City Hall, and the Whispering Bay waterfront, which wraps the southeastern edge of the Specific Plan Area. This district is bordered by Marina Boulevard / Marina Circle and Civic Center Boulevard to the north. West of Civic Center Boulevard are the City’s administrative offices, the Solano Yacht club, and open space and wetland areas.

This district also includes the former Whispering Bay marina, which was developed in the 1960s as a private marina, with docking facilities. Over the years, the docks and slips deteriorated and were removed. Siltation, lack of maintenance, and dredging have limited the site to its current use as a surface parking and storage facility. The limited utility of the site currently, along with its location within a mile of transit, makes the area along Whispering Bay a key redevelopment and infill opportunity site.

Several undeveloped properties are located on the southern end of the Suisun Channel, near the terminus of Harbor Park Drive and Whispering Bay Lane. Development of these vacant properties and redevelopment of the former marina has the potential to provide a circulation connection that joins Marina Boulevard to Civic Center Boulevard.

Across Suisun Slough from the Whispering Bay Neighborhood is Pierce Island, an undeveloped area currently designated as a dredge material disposal site and permanent open space. The island was formerly used for a series of oxidation ponds for sewage treatment.

2.2.1 Suisun City General Plan and Zoning Code
Development in Suisun City must comply with the Suisun City General Plan and Zoning Code. The General Plan establishes goals and policies that are designed to guide development and conservation throughout the City’s Planning Area. The is required by State law to be consistent with the General Plan. The land use designation in the General Plan for the Area is “Downtown Waterfront Specific Plan.” The WDSP allows development consistent with the land use plan provided in Chapter 3.

The General Plan contains policies and goals relevant to the WDSP Area.

Several elements of the General Plan have policies that form a framework for the Specific Plan Area.

General Plan guiding principles that have the greatest general bearing on development in the Specific Plan Area and with which the WDSP must be consistent include the following:

Community Character

1. Suisun City will strive to enhance the City’s authentic, local identity as a vibrant waterfront community.
▪ Focus higher-density development and mixed-use projects in areas adjacent to the train/intermodal depot.

▪ Preserve and enhance natural resources and minimize negative environmental impacts.

Transportation

7. Suisun City will provide choices for attractive, convenient transportation.

2.2.2 San Francisco Bay Plan
The San Francisco Bay Conservation and Development Commission (BCDC) is a state agency created to protect the bay as a natural resource, to guide development, and enhance public access.

BCDC has adopted the San Francisco Bay Plan, which includes land use policies that apply to portions of the Specific Plan Area and areas adjacent to the Specific Plan Area. The Bay Plan, which was initially adopted by the BCDC in 1968, signed into law by the California Legislature in 1969, last updated in 2012, and amended in October 2019, encompasses the San Francisco, San Pablo, and Suisun Bays and the portions of the Sacramento-San Joaquin Delta as far east as Collinsville.

The San Francisco Bay Plan’s objectives are to protect the bay as a great natural resource for the benefit of present and future generations and to develop the bay and its shoreline to their highest potential with the minimum of Bay filling. According to the Bay Plan, filling may only be permitted for water-related purposes that provide substantial public benefits, ports, water-related industrial uses, airports, freeways, bridges, recreational opportunities, wildlife refuges, and public shoreline access.

The Bay Plan also recognizes the value of fish and wildlife resources.

Policies have been established to protect and maintain remaining marshes and mudflats, the remaining water volume and surface area of the Bay Region, and adequate freshwater inflow into the bay. The BCDC has regulatory authority over all uses and development within 100 feet landward of, and parallel to the shoreline of the San Francisco Bay. 279

D. Historic Residential (H R) Zone
This zone, along with Main Street and the waterfront, comprise the first area of settlement, which contributed significantly to the culture and development of the City. The HR zone contains several historic structures, which are a highly valued part of the City's heritage. The Solano County Landmarks Commission has, through the publication:
“Our Lasting Heritage,” documented the historical and architectural value of a number of properties in the HR area. Some of these are good examples of earlier architectural styles and exemplify elements of outstanding attention to design, detail, materials, and craftsmanship.

The Cultural Resources chapter within Volume II, Technical Background Reports of the General Plan (adopted in May 2015) lists known cultural resources and contributing resources to the Suisun City Historic District, an area bounded by Sacramento Street to the north, West Street to the west, Cordelia Street to the South, and Kellogg and Main Streets to the east. This district comprises of 95 contributing buildings, including residences, commercial, and social/religious buildings that have historically been associated with the Downtown Core of the City and retain their integrity.

The specific purpose and intent of the HR zone, as summarized by the following objectives, is to ensure that this area continues as a viable residential neighborhood and ensure the City’s cultural heritage, as reflected in its historic structures, sites, and features, is not destroyed. ▪ Preserve and protect historic structures.
▪ Preserve and maintain the Historic Residential area embodied in the HR zone as a cohesive neighborhood unit.
▪ Enhance property values.
▪ Ensure that the community's cultural heritage, as reflected in the built environment, is not lost.
▪ Encourage redevelopment of vacant and incompatible structures to develop in accordance with the historic character of the zone. ▪ Provide for rehabilitation, additions, and modifications to existing structures in a manner that is sensitive to the historic qualities of these structures.

The HR zone applies to the existing Old Town residential neighborhood and is intended to accommodate a mix of single-family homes, duplexes, multi-family dwellings, and compatible non-residential uses that maintain the historic character of the area. This zone permits residential development of between six (6) to eighteen (18) dwelling units per net acre.

No mobile home, as defined by the City Zoning Code, or camping unit, designed to be carried or towed by a motor vehicle, tent, mobile living unit, boat, trailer, or freight van shall be stored in any front or side yard 286

adjacent to a public street within the HR zone longer than seven (7) consecutive days without obtaining a Temporary Use Permit, as addressed in Chapter 7. Storage beyond the time allotted for a temporary use is prohibited. Manufactured homes must comply with the standards for manufactured homes in Chapter 18.54 of the City Zoning Code and with the design standards applicable to the HR zone, addressed in Chapter 6 of this Specific Plan.

3.1.2 Commercial Zones
Six commercial land use zones are established:
▪ MSMU – Main Street Mixed Use
▪ DMU – Downtown Mixed Use
▪ HC – Historic Commercial
▪ DMU – Downtown Mixed Use
▪ DC – Downtown Commercial
▪ WC – Waterfront Commercial
A. Main Street Mixed Use (MSMU) Zone
This zone is primarily devoted to preserving and enhancing the mix of retail, entertainment, and destination uses in the Downtown Core. This Specific Plan is intended to encourage the historic mix of uses, which typically consisted of a retail or personal service business in the ground floor storefront facing Main Street, with small commercial, professional offices or residential uses on the upper floor(s) and behind the Main Street frontage use.

Main Street retailers have traditionally sold a combination of convenience items and services for everyday needs (e.g., butcher, baker, shoe shop) and specialty items, such as clothing, jewelry, gifts and antiques.

Restaurants, cafes, and similar eating and entertainment establishments were also commonplace. Large bulk retail businesses, such as furniture sales, automotive, or wholesale uses were generally found only on the fringes of the Downtown, if at all.

Permitted and conditionally permitted uses within this zone are identified in Table 3-5.

Notes:

1. Specialty retail shops are small retail stores that offer distinctive merchandise, typically sourced locally or regionally, and intended to cater to visitors, rather than primarily serving the local population.

Specialty retail shops do not include the sale of age-restricted goods or the provision of age-restricted services.

2. Permits the same type of residential dwellings as the RHD zone.

Special use regulations in the City’s Zoning Code shall apply to the Specific Plan Area, unless otherwise noted in Section 3.1.4.

Chapter 3 | Land Use Regulations

B. Historic Commercial (HC) Zone
This zone applies to the area south of Harbor Plaza facing Main Street and east to Kellogg Street. This area is currently predominantly residential but is expected to gradually convert to commercial and/or office uses, which are compatible with residential uses. Because most of the structures are historic and still occupied by residential uses, any commercial conversions of these structures should preserve the significant historical characteristics of the buildings and avoid adverse impacts to the nearby residences.

Therefore, office and commercial uses should be low intensity in nature and occur as conversions, rather than replacement of structures.

Generally, residential and public uses are permitted and commercial/office uses are listed as conditional uses. Commercial uses for which a valid City business license has been issued, which are existing at the time of adoption of this document are considered to be conforming uses and do not require a Conditional Use Permit to continue. Allowed uses permitted within the HC zone are indicated in Table 3-6.

4.1.1 Regional Vehicular Access
Regional access to the Waterfront District Specific Plan (WDSP) Area (Specific Plan Area) is shown in Figure 4-1. Although access from the east and west appears adequate, access to the Waterfront District from the north is hindered by the highway. To access the Specific Plan Area, most drivers must get on Highway 12 (SR 12) and use the Civic Center Boulevard exit if they are traveling eastbound or the Main Street exit if they are traveling westbound. As an alternative route, drivers can use the at-grade intersections at Pennsylvania Avenue to the west, entering Suisun City via Cordelia Street or at Marina Boulevard to the east. ▪ SR 12 is a four-lane, east-west oriented highway that provides access for Suisun City to Interstate 80 about two miles to the west. Near Suisun City, it has two at-grade intersections with Marina Boulevard and Pennsylvania Avenue.
▪ Cordelia Street is a two-lane rural arterial roadway that runs east-west from Interstate 80 to the west and to Main Street to the east. It is relatively narrow, with gravel shoulders. As it approaches Suisun City’s Old Town area, it is designated as Cordelia Street and is wider, with on-street parking and sidewalks.

4.1.2 Local Vehicular Access
Within and adjacent to the Specific Plan Area, existing and planned vehicular access roadways are shown in Figure 4-1, by their proposed classification as either an expressway, arterial, collector, or local street.

Primary street segments in the Specific Plan Area are briefly summarized in the bullets that follow.

October 2023 Page 4-3
▪ Main Street is a two-lane arterial that runs north-south through the historic commercial area. Commercial land uses and on- street parking line each side of the street. The northern terminus of Main Street links with the SR 12 westbound on- and off-ramps.

To the south, it connects with Cordelia Street.
▪ Civic Center Boulevard is a two-lane divided collector street with a landscaped median that generally runs north-south from its interchange with SR 12 to a cul-de-sac just south of City Hall. ▪ Driftwood Drive is a two-lane local collector that is oriented east to west, connecting Marina Boulevard and Civic Center Boulevard with Main Street and Benton Court.
▪ Lotz Way is a two-lane, east-west arterial that extends from Main Street to Marina Boulevard. West of Civic Center
Boulevard, Lotz Way serves as an arterial link between Main Street and the SR 12 eastbound on and off-ramps. East of Civic Center Boulevard, Lotz Way operates as an arterial street to its present terminus at Marina Boulevard.
▪ Marina Boulevard is an arterial/collector that runs from Railroad Avenue north of SR 12 to the marina neighborhoods adjacent to Suisun Slough. Marina Boulevard has an at-grade, signalized intersection with SR 12. It is four lanes wide north of SR 12 and two lanes wide, with bike lanes, south of SR 12. ▪ Railroad Avenue is an arterial that runs from Sunset Avenue and terminates just west of Marina Boulevard. It is a four-lane roadway with a median and bike lanes east of Birchwood Court.

West of this, Railroad Avenue is a wide, two-lane roadway, with bike lanes and on-street parking. West of the current terminus of Railroad Avenue, the street is planned to continue to the west as a future four-lane arterial to connect with the extension of Main Street/Denverton Road.

4.1.3 Plann ed Vehicular Circulation Improvements
As the Specific Plan Area continues to develop, new multi-modal facilities will enhance the circulation network. The timing and construction of these projects will be dependent on available grant funding, Capital Improvement Program budgeting, and private development applications.

Circulation system improvements are indicated by dashed lines in Figure 4-1. Street sections for typical streets in the Specific Plan Area are provided in Figures 4-2 through 4-8.
▪ A new collector is proposed parallel to and east of the railroad line, between Spring Street and Cordelia Street (called “Old Town Bypass” in the 1999 Specific Plan).
▪ Streetscape improvements along Main Street, particularly to update the west side of Main Street (Figure 4-2).
299
Chapter 4 | Traffic + Circulation

▪ New streets to serve the 30-acre commercial property, north of SR-12 to include:
- Extension of Railroad Avenue, west of Marina Boulevard to the extension of Main Street/Denverton Road as a four-lane divided street with bike lanes (Figure 4-3).
- An at-grade crossing of the railroad tracks, to connect with Clay Street in Fairfield.
▪ Improvements or enhancements to existing Downtown arterial and collector streets to support safe multimodal travel and access (Figures 4-4 through 4-6).
▪ New local neighborhood roadways and alleys to connect and serve new residential and mixed-uses development within opportunity sites in the Specific Plan Area (Figure 4-7 and 4-8).

4.1.4 Roadway Design Standards
The City's Standard Specifications document provides construction specifications for public streets. Planned arterial, collector, and local streets, including Main Street, shall be governed by the Specific Plan standards and typical sections that follow in this chapter. Where a conflict arises, the Specific Plan standards will control. Exceptions to these standards may be granted by the Development Services Director, where a different solution may be needed due to property constraints or to enhance pedestrian, bicycle, or transit safety and convenience.

Entry treatments walls, landscaping, and related streetscape or frontage improvements are further addressed in the development and design standards in Chapter 6.

2. Motor court or alley rights-of-way shall be a minimum width of twenty (20) feet, in order to accommodate vehicles. Landscape areas along each side of the right-of-way must be a minimum of three (3) feet.

4.1.5 Parking
An existing 265-space Caltrans park-and-ride lot is located adjacent to the train depot, with access from Lotz Way. Several public parking lots exist, including lots alongside the Main Street promenade, adjacent to the waterfront, between Driftwood Drive and Solano Street. A common parking area currently exists adjacent to Harbor Plaza. Smaller parking areas also exist adjacent to the waterfront, south of Harbor Plaza.

New development in the Specific Plan Area shall be required to provide parking in accordance with the parking standards provided in Section 6.

5.4. The City encourages new shared parking areas to serve new development, particularly infill development on relatively smaller parcels.

Use of on-street parking should be maximized.

Commercial and mixed-use development in the Specific Plan Area, south of SR 12, would provide parking on-site through a combination of surface parking lots and parking garages and garages below podium level decks.

Parking for new residential development is to be accommodated through a combination of surface, garage, and tuck under parking configuration.

Parking to serve development on the 30-acre property, north of Highway 12, is to consist of a combination of on-street parking, shared surface parking lots, and parking garages.
307
Chapter 4 | Traffic + Circulation

4.2 Public Transportation

4.2.1 Rail Transportation
The main line of the Union Pacific Railroad runs along the western border of Suisun City, carrying both commuter and freight rail traffic.

Regional commuter trains stop at the depot between Main Street and the tracks. East of Main Street and north of Lotz Way is a 265-space “Park-n- Ride” lot owned by Caltrans. This lot is used by both rail passengers and visitors to Specific Plan Area.

The existing train depot is a multimodal facility, with parking and drop-off areas to accommodate vanpools, taxi services, fixed-route bus service (both as a stop and a transfer point between bus routes), intercity and commuter bus service, and intercity rail service.

4.2.2 Water Transportation
Suisun Channel provides water access to the Old Town area and surrounding neighborhoods. There are approximately 155 existing boat slips adjacent to the Channel. There are approximately 100 parking spaces for vehicles with trailers at the boat ramp in the South Waterfront district, with an additional adjacent lot, which primarily serves the Peytonia Slough Ecological Reserve.

Existing boat use in the Channel is described as moderate, with peak periods occurring during the summer months and on weekends. Various existing marinas on the east side of Main Street, one public boat launch facility and public guest docks provide access to the Channel. Channel navigation is regulated by the City's Police Department, which maintains a part-time harbor patrol, consisting of one officer on an as-needed basis. 308

4.3 Bike and Pedestrian Circulation

4.3 Bike and Pedestrian Circulation

4.3.1 Bike and Pedestrian Facilities
With the relatively compact development pattern with buildings primarily built close the front property line, the grid and modified grid transportation network, the lack of overly wide streets, and other features, the Specific Plan Area is a relatively bicycle- and pedestrian- friendly area.

Existing bike routes within the Specific Plan Area consist of:
▪ Class I bike trails including the bike/pedestrian promenade circling the Suisun Channel, the Central County Bikeway Trail along the drainage canal north of Highway 12, and a bike/pedestrian trail along the east side of Marina Boulevard, north of Driftwood Drive and south of SR 12 on the Grizzly Island Trail that connects from the Specific Plan Area to Grizzly Island Road.
▪ Class II on-street bike lanes on Driftwood Drive, between Whispering Bay Lane and Marina Boulevard.

In addition to these existing, designated facilities, local streets in the Specific Plan Area are also generally low-traffic, low-vehicle-speed, safe areas for biking.

Most streets in the Specific Plan Area have sidewalks. Pedestrians can access the waterfront from the west side of Civic Center Boulevard along the channel. A linear pedestrian walkway/bicycle path circles around the Channel between City Hall and the cul-de-sac at the end of Walnut Street, north of the City boat launch facility.

4.3.2 Planned Bike and Pedestrian Circulation
Improvements
Pedestrian/bicycle circulation is to be provided by a combination of a waterfront/public access path system, neighborhood streets/sidewalks, and striped bicycle paths on arterials and collectors.

The General Plan Circulation Element designates bike routes in the Specific Plan Area as collectors and arterials that require striping and signage for Class II bike paths or Class I bike routes, consistent with Error! Reference source not found. and the WDSP standards. The bike/pedestrian circulation system, shown in Error! Reference source not found., indicates the general location of these facilities. 309

4.3 Bike and Pedestrian Circulation
October 2023 Page 4-15
New on-street bike facility and off-street bike and pedestrian facility improvements or enhancements, include:
▪ Providing bike lanes on Lotz Way, Driftwood Drive, Marina Boulevard, Civic Center Boulevard, Sacramento Street, Cordelia Street, and Railroad Avenue.
▪ Supporting future development of the property at the northwest corner of SR 12 and Marina Boulevard with on- and off-street bicycle facilities that ensure internal safe and convenient bicycle movements and connect externally to surrounding regional trails, Main Street, and Downtown Fairfield.
▪ Providing continuous north-south on-street bike lanes along Railroad Avenue, parallel to the train tracks, Whispering Bay Lane, and an off-street path connecting Civic Center Boulevard with Marina Boulevard.
▪ Providing or improving on-street bike facilities along the key connecting east-west roadways to waterfront and regional trails, and neighborhoods in the Specific Plan Area, including Lotz Way, Driftwood Drive, Sacramento Street, Francisco Drive, and Cordelia Street.
▪ Expanding on the Class I bicycle/pedestrian path/promenade system following the Suisun Channel and linked to key street access points. The first leg of this system from Walnut Street, around the Civic Center to the current terminus of Civic Center Boulevard, is now in place. Additional improvements include:
- Extension of the trail at its eastern terminus through the waterfront open space along Whispering Bay and following the drainage canal, south of Whispering Bay Lane.
- Extension of the pedestrian promenade that terminates on the west side of the channel south to the boat launch facility in the Southern Waterfront area, to connect with State Park trails south of the Specific Plan Area.
▪ Identifying opportunities to provide shaded areas with drinking fountains, benches, and other amenities to further encourage the use of the City’s off-street bicycle and pedestrian facilities. ▪ Collaborate with local and State agencies, such as the City of Fairfield and Caltrans, to improve the safety of the existing pedestrian environment, including intersection median
enhancements and other improvements to pedestrian facilities.

When complete, the path system will follow the entire waterfront frontage from the boat launch ramp on Kellogg Street to the Marina neighborhood, adjacent to Whispering Bay. These improvements, along with connections they provide to other pedestrian/bicycle facilities, meet the Suisun City General Plan Guiding Principles, including:
311
Chapter 4 | Traffic + Circulation

▪ Ensure safe and efficient walking, biking, driving, and parking in the Downtown.
▪ Design for active pedestrian and bicycle-friendly paths and streets, as well as public spaces.
▪ Encourage a healthy living environment.

In addition, with future development, all new local streets will enhance the local pedestrian system, improve Downtown connectivity, and foster an environment that encompasses safe bicycle and pedestrian travel.

Crossing improvements or enhancements to support safe bike and pedestrian crossings are also encouraged at key intersections within new development areas.

CHAPTER 5| OPEN SPACE + CIVIC AND

SERVICES

5.1 Open Space + Civic and Services
The provision and preservation of open space, waterfront access, and other civic facilities are critical to creating the character of development envisioned by this Specific Plan. Both existing and planned features within the Waterfront District Specific Plan Area (Specific Plan Area) are depicted in Figure 5-1, “Recreation and Open Space Diagram.” Park, open space, and civic facilities in the Specific Plan Area include:
▪ Suisun Channel. The entire length of the Suisun Channel, north of Suisun Bay, provides access for recreational boats between the Waterfront District and other locations, including the Sacramento- San Joaquin Delta and San Francisco Bay. A public promenade and multi-use path system circles the channel. The channel requires periodic dredging, which is done periodically by the Army Corps of Engineers, as the channel is under federal control. The City or private entities are responsible for dredging the remainder of the navigational channel.
▪ Natural Open Space Areas. Natural open space includes wetland areas adjacent to City Hall and Whispering Bay, the Pierce Island wetland mitigation site, and the open space along the drainage channel south of Whispering Bay Lane. The
channel/slough winds through the Suisun Marsh. The channel and marsh offer fishing and birdwatching opportunities and recreational boating, cruising, water skiing, jet skiing, kayaking, and other water- related activities. Approximately 50 percent of Pierce Island is to be retained as a permanent tidal wetland. The remainder of the island is managed as a permanent dredge material disposal site.

Levee and dike improvements are planned to stabilize the island. ▪ Public and Private Marinas. The Suisun City Marina provides 155 rental berths, a 300-foot-long visitor dock, and a boat launch ramp that capitalizes on the waterfront.

October 2023 Page 5-3
▪ Southern Waterfront Area Boat Launch
Expansion/Events. The existing boat launch facility is proposed to be expanded and enhanced. Plans prepared for the Southern Waterfront Area envision enhancing the marina facilities, improving landscaping, retaining the parking capacity, creating clear pedestrian and vehicular circulation, extending the waterfront promenade, and accommodating new mixed-use
development. The waterfront promenade trail is proposed to be extended from the Delta Cove neighborhood to the state-owned nature trail to the south. This site could accommodate new marina slips and a new two-story, retail/office mixed-use building on the waterfront and smaller buildings for water recreation and storage. This site could also accommodate a public viewing area/pier, plazas and greens for waterfront events, a
reconstructed dock for crew and kayak use, and a relocated fuel dock.
▪ Transportation Center. The historic train depot functions as an intermodal transportation facility housing a waiting area and ticketing for the Capitol Corridor line, intercity and local bus service, and bicycle parking facilities. Parking for commuters is accommodated in the Caltrans park-and-ride lot across Main Street from the train depot.
▪ Main Street. The City proposes to improve Main Street with new landscaping, paving treatments in strategic locations, and appropriate street fixtures (e.g., lighting, benches, trash receptacles, etc.), in coordination with more recent streetscape improvements on the east side of the street. Streetscape features along Harbor Plaza, Main Street, and the Transportation Center will have a consistent design theme.
▪ Civic Center. The Civic Center area on the east side of the channel includes City Hall, the Suisun City Housing Authority, the Police Department, the Solano Yacht Club, and marina slips.

Waterfront open space and trail facilities in this area are proposed to be extended south along the Whispering Bay
waterfront.
▪ Waterfront Parks/Plazas. In addition to the waterfront recreational facilities planned in the Southern Waterfront area, several small existing waterfront parks are located along the Waterfront promenade.
̶ Harbor Plaza, on Main and Solano Streets, adjacent to the waterfront promenade, is an existing one-acre park with a raised outdoor stage, gazebo, and sectioned turf areas.

Special events are focused on Harbor Plaza.
̶ Sheldon Plaza is an existing one-acre park with open turf area and waterfront views at the northern head of the Suisun 315
Chapter 5 | Open Space + Civic and Services

Channel and adjacent to the waterfront promenade and hotel and office uses.
̶ North of City Hall is Mike Day Park, is a three-acre park with a playground, picnic areas, and open turf play areas. South of the park and behind City Hall are open turf areas, referred to as “City Hall Point.”
▪ Neighborhood Parks. Several neighborhood parks exist within the Specific Plan Area.
̶ Todd Park, located across the street and to the east of City Hall, serves as a shared greenspace for the surrounding “Harbor Park” residential development.
̶ An oval, two-acre park, surrounded by local streets, is integrated into the “Victorian Harbor” residential
development just northwest of Crystal Middle School.
▪ Parking Facilities. Public parking facilities are located in the Caltrans park-and-ride lot north of Lotz Way, on the east side of Main Street, adjacent to the expanded marina basin, in and around the Harbor Plaza, on Main Street, on streets in the Downtown Core district and adjacent to the portion of the marina slips south of Harbor Plaza, as described in Chapter 4.

Refer to Chapter 4 for additional information on existing and proposed new parking facilities and Chapter 6 for parking standards.

5.2.1 Water
The City provides domestic water for all properties located within its boundaries. Domestic water is provided through the Suisun‐Solano Water Authority (SSWA). Suisun City and Solano Irrigation District (SID) formed a Joint Exercise of Powers Agreement in 1976 to provide a long- term water supply for the City. In 1990, the partnership became a full Joint Powers Authority named the SSWA, resulting in the reconstruction and modernization of the old Suisun Water System.

The City handles the local billing and requests for water and sewer service and the SID delivers water to the meter of each property. The SSWA Board, which consists of the City Council and the SID Board, provides policy direction for SSWA (Suisun City).

Water Sources
Implementation of the 2035 General Plan designates land uses that, if developed to full build-out, would increase water demand. Based on the projected population of 32,400 at 2035 General Plan build-out and demand factors presented in the Urban Water Management Plan (UWMP), the total projected water demand at build-out of the 2035 General Plan would be approximately 4,251 acre-feet per year (afy).

This analysis examines the estimated increase in water demand in relation to the existing conditions to estimate the availability and adequacy of water supply. Water supplies for the City are provided by the SSWA.

The SSWA receives water supplies from the U.S. Bureau of Reclamation’s Solano Project and the California Department of Water Resource’s State Water Project (SWP), both of which are wholesaled by the Solano County Water Agency and Solano Irrigation District.

Existing and projected water demands in the SSWA service area will be met by the water supplies described above and contract entitlements for each agency are summarized in Table 5-1. In 2010, the SSWA service area had a total of 4,144 afy of potable water supplies. This total is anticipated to increase to 6,000 afy by 2035.

SSWA currently does not use any groundwater in its system. SSWA delivered groundwater produced by a well owned by City of Suisun City until 2001. The need for the well was eliminated by the installation of the Benton Court and Suisun Valley Pumping Plants in 2000–2001. There are no plans to resume service from this well or the Suisun Valley in general due to high mineral content in the groundwater, sufficient alternative surface water supplies, and the need to replace miles of pipeline at considerable cost in order to convey water from the Suisun Valley back to the main SSWA service area.

The Fairfield-Suisun Sewer District (FSSD) oversees wastewater collection and treatment and water recycling services in the City of 317
Chapter 5 | Open Space + Civic and Services

Fairfield, Suisun City, and Travis Air Force Base. Currently, there is no reclaimed water use nor are there plans to provide reclaimed water within the SSWA service area because there is no conveyance infrastructure in place to deliver recycled water from the FSSD Fairfield- Suisun Subregional Wastewater Treatment Plant (WWTP) to the SSWA service area. SSWA’s capital improvement plans will in the future review the potential for future recycling and options for financing. Cooperation with the City of Fairfield and the FSSD would be required to implement any future actions, and neither of these agencies has planned water recycling projects.

Facilities
There are four storage tanks in the water system, including:
▪ Cement Hill Tank (2 million gallons). The Cement Hill Tank is supplied by the Cement Hill Water Treatment Plants No. 1 and 2, which delivers water to Suisun City, the unincorporated area of Tolenas and the Suisun Valley. The Gregory Hill Tank receives its water from the Suisun City Distribution system, which is pumped from the Benton Court Pumping Plant located in Old Town Suisun City with a pumping capacity of 1,000 gpm.
▪ Gregory Hill Tank (2 million gallons). The Gregory Hill Tank supplies water to the Suisun Valley through the Suisun Valley Pumping Plant at a rate of 400 gpm and/or gravity feeds back into the Suisun City distribution system.
▪ Sports Complex Tank (1.5 million gallons). The Sports Complex Tank is a supplemental ground level storage tank with a pump to boost into the distribution system at 2,000 gpm. ▪ Suisun City Corporation Yard Tank (1 million gallons).

The Suisun City Corporation Yard tank is also a supplemental ground level storage tank with a pump to boost into the distribution system at 1,200 gpm. These facilities would provide a peaking storage of 20 percent and an emergency storage of approximately one full anticipated maximum day demand, and will also provide fire storage of 420,000 gallons. The table below lists the facilities in the SSWA water system.

As a result of a condition assessment conducted by the SSWA in 2012, it has been determined that an additional Cement Hill Tank, Cement Hill Tank 2 is needed to meet demands.

Service Demand
In December 2012, the SSWA completed its Water System Review, a report which projected updated information on the anticipated growth and development within its service area, as well as a revised estimate for water demand. Based on a review of historic water use records over the last 15 years, the Annual Average Day (AAD) demand of each year was used to calculate respective factors for the Maximum Month and Maximum Day demands for each year. Table 5-3 identifies the estimated peak build-out demand, which was calculated using the highest demand factors occurring over the last 15 years (SSWA 2012: 4). 319
Chapter 5 | Open Space + Civic and Services

Table 5-3: Water Usage Demand Factors
Source: SSWA Water System Review (December 12, 2012).

The ultimate maximum day demand is estimated at 6,470 gpm (9.3 MGD) for the service area. This represents a significant decrease from the previous figure of 11.08 MGD that was estimated in the 2007 Water Supply Options report (SSWA 2012: 6).

The SSWA water demand is anticipated to be less than available water supplies through 2035 in normal water years. As shown in Table 5-1, water supply is projected to be sufficient in normal water years over the UWMP’s 20-year planning period from 2015 to 2035. Although Table 5-4 shows that water supply in single and multiple-dry water years is insufficient to meet demand within the SSWA service area over the 20- year planning period, a joint powers agreement between SID and Suisun City ensures that water will be provided from the SID water supplies and therefore there will be sufficient water supplies to meet demands (SSWA 2011:66). A footnote in the UWMP indicates that:
“The apparent negative supply totals are a result of the methodology used for calculating supply reliability. In fact, per the joint powers agreement between SID and City of Suisun City the commitment has been made that water will be provided for the service area from the SID supply and therefore there will not in fact be a water shortage” (SSWA 2011:67).

Section 3.0 of the 1990 SSWA Implementation and Lease Agreement states that the “City and District may agree to add additional lands to the Joint Service Area covered by this Agreement. Such action shall be accomplished only by amendment to this Agreement or by a separate written agreement...” According to SID, this process would require future negotiations to an amendment of the JPA.

Water demand is anticipated to be less than available water supplies through 2035 in normal water years. A joint powers agreement between SID and Suisun City ensures that water will be provided from the SID water supplies and therefore there will be sufficient water supplies to meet demands.

Conservation & Legislation
The 2035 General Plan includes measures to ensure that sufficient water sources are made available to serve new development. The City will condition approval of new developments on the availability of sufficient water supply, storage, and fire flow (water pressure), per City standards and require demonstration of adequate long-term water supply for large development projects as defined in Water Code 10912(a). 321
Chapter 5 | Open Space + Civic and Services

The City will also require the use of water conservation technologies, such as low-flow toilets, efficient clothes washers, and efficient water- using industrial equipment in new construction, in accordance with code requirements; encourage use of recycled water for outdoor irrigation, fire hydrants, and commercial and industrial processes; and require new development to incorporate climate-appropriate landscaping to reduce water demand. In addition, the City will comprehensively assess water supply and demand and identify a range of local conservation measures to be implemented through the UWMP.

In addition, the 2035 General Plan includes policies committing the City to ongoing water supply planning with Solano County Water Agency, Solano Irrigation District, and other local jurisdictions and initiating a study with the SSWA and the Solano County Water Agency to determine the feasibility of extending a connection from the SSWA water treatment facility to Suisun City so that the City may directly utilize its Solano Project water entitlement. The City will also support FSSD efforts to explore the feasibility of using treated wastewater for irrigation in parks, landscaped areas, and other appropriate locations.

5.2.2 Wastewater
The City of Suisun City and the Fairfield-Suisun Sewer District (FSSD) jointly operate and maintain the wastewater collection system that serves the City. FSSD owns and operates the trunk sewer system, which includes all 12-inch and larger sewers and the major pump stations and force mains that convey wastewater to the District’s wastewater treatment plant. FSSD also owns, operates, and maintains all of the pump stations in the City’s wastewater collection system. The City, along with the City of Fairfield and Travis Air Force Base, is a “satellite collection system” to FSSD and owns and operates only those 10-inch and smaller gravity sewers within its service area. The City’s portion of the system consists of approximately 74 miles of gravity sewer. The City does not own or operate any sanitary sewer pump stations or force mains.

Wastewater flows travel by gravity and are pumped by smaller stations to four major pump stations which pump wastewater to the treatment plant.

The wastewater treatment process includes screening, primary treatment, intermediate treatment by oxidation towers and intermediate clarifiers, secondary treatment with aeration basins, and secondary clarifiers and tertiary treatment via filtration and disinfection. Waste solids are thickened and treated in anaerobic digesters. Then, solids are further concentrated before being disposed at the Potrero Hills Landfill. Flow is continuously measured at the pump stations. On occasion, flow monitoring may be deployed into the district’s gravity lines to evaluate system capacity and surcharging during storms. Suisun City is served by the Suisun Pump station and three smaller stations: Lawler I Pump Station, Lawler II Pump Station, and Crystal Street Pump Station. 322

Within the last decade, numerous improvements have been made to the treatment facilities to increase peak capacity and improve upon the treatment process. A treatment plant project to replace chlorine disinfection with ultra‐violet disinfection was completed in 2011. The Central‐Suisun Forcemain Equalization Project, completed in 2013, increased the reliable peak capacity of the Suisun Pump Station from 31.7 to 38.3 mgd, allowing for more water to be processed. The Suisun Forcemain improvement project has enabled the pump station to meet current and near‐term capacity needs until growth and revenue projections become more certain. New projects identified in the master plan will still be needed to meet long‐term capacity requirements.

To date, system evaluation and capacity assurance of the City’s collection system has consisted of observation of sewer system performance during dry and wet weather and enforcement of the City’s design standards for new sewers. Capacity assessment has been handled historically by the Fairfield Suisun Sewer District for the geographic area including Fairfield, Suisun City, and portions of Solano County served by the District. In 2013, the District completed a Sewer System Master Plan (an update of its previous Master Plan completed in 2007). The Master Plan identified all parcels within the service area of Suisun City, land use type for each parcel, and the status of developed versus undeveloped. Wastewater flows generated by each parcel were calculated and imported into a hydraulic model of the sewer system.

The Master Plan utilized a hydraulic model to assess the current and future flows and capacity needs of all gravity sewers, 12-inches in diameter and larger; these larger trunk sewers have a greater potential for capacity deficiency due to extended tributary areas. The future evaluation and capacity assurance of City sewers will include continued observation of system performance during wet weather; expansion of the hydraulic model as needed, and enforcement of design standards to ensure that new sewers are sized with adequate capacity to serve new 323
Chapter 5 | Open Space + Civic and Services

development. In the future, the City plans to prepare a Master Plan for its sanitary sewer system, which will be coordinated with the District’s Master Plan and hydraulic model, in order to develop a capital improvement program to address any identified capacity issues.

The FSSD recently completed a treatment plant expansion that increased the average dry weather capacity from 17.5 mgd to 23.7 mgd and reliable peak‐flow capacity from 34.8 mgd to 52.3 mgd. Currently there are no scheduled projects in Suisun City for collection system improvements.

5.2.3 Storm water
The City of Suisun City Public Works Department maintains an inventory of facilities and coordinates necessary improvements to ensure capacity required to serve new development. The City’s Stormwater Management and Discharge Control ordinance was enacted with the intent to regulate non-stormwater discharges to the public storm drain system, protect the public storm drain system from spills dumping or disposal of materials other than stormwater, and reduce pollutants in stormwater discharges, to the maximum extent possible.

The City’s storm drainage system, which includes creek flows along McCoy Creek, Laurel Creek, and Union Avenue Creek, would likely be contained within the existing creek bank during a 100‐year storm, except for localized flooding and standing water that may occur during brief, intense storms when runoff exceeds storm drain system capacity.

As a participant in the National Flood Insurance Program (NFIP), Suisun City is required to adhere to floodplain management policies that include sound land use practices. The Federal Emergency Management Agency (FEMA) administers the NFIP through the Federal Insurance Administration. FEMA produces flood Insurance Rate Maps (FIRMS) which identify flood hazard areas and restrict development in these areas for the communities participating in the NFIP.

FSSD and City Activities
The City’s Municipal Review Permit (MRP) was adopted by the Water Board on November 18, 2015. The MRP delineates requirements to ensure that storm water quality is protected. The breakdown of shared activities between the City and District are delineated through a Drainage Maintenance Agreement and are specified as follows.
▪ District Activities. District activities include maintenance of storm water pump stations, industrial and commercial site controls, public information and participation, water quality monitoring, mercury controls, PCBs control, copper controls, PBDE, and legacy pesticides control. The Sewer District has assumed responsibility for operation and maintenance of pump stations located in Suisun City as defined under the “Regional Facilities” in the Drainage Maintenance Agreement.
▪ City Activities. Municipal maintenance, new development compliance, illicit discharge detection and elimination, construction site controls, pesticide toxicity control, trash control, exempt and conditionally exempt discharges. As detailed in the Drainage Maintenance Agreement, the City is also responsible for the maintenance of “Local Facilities,” which includes storm drain pipelines, box culverts, concrete lined channels, improved earth channels, natural creeks, detention basins, street sweeping, data management, and fencing. The City also maintains a number of open channel storm drains of varying sizes. The larger channels are blanketed with natural vegetation and require periodic cleaning. There are approximately 14,500 feet of large open channels and 20,000 feet of smaller ditches.

Upgrades to storm drainage pipes over the past 10 years include improvements required and funded by new developments. All new commercial and residential subdivisions are required to conform to the City storm drainage standards, protect water quality, and meet Regional Water Quality Control Board requirements. Among these requirements, in 2009, the San Francisco Bay Region Water Quality Control Board adopted the Municipal Regional Stormwater NPDES permit (NPDES 325
Chapter 5 | Open Space + Civic and Services

permit)1 for the San Francisco Bay Region. The intent of the permit is to mitigate the potentially detrimental effects of urban runoff through site design and source controls early in the development review process and provide guidance in the selection of appropriate best management practices (BMPs).

Suisun City is the lead agency responsible for review of projects for stormwater conformance with applicable, laws, policies, and guidelines, including implementing the C.3 provision of the NPDES permit, which requires the City implement measures to reduce stormwater pollution and increased stormwater runoff, volume, and duration from new development or redevelopment projects.

Under the C.3 provision, new development or redevelopment in the City that creates and/or replaces 10,000 square feet or more of impervious surface (collectively over the entire project site), including commercial, industrial, residential housing subdivisions, mixed-use and public projects; and redevelopment projects resulting in the alteration of more than 50 percent of the impervious surface of a previously existing development, shall be required to implement LID source control, site design, and stormwater treatment measures, designed to treat 100 percent of run-off for a project’s drainage area on-site or at a joint stormwater treatment facility.

The C.3 provision of the NPDES permit also allows projects alternatives to complying with the above standards under provision C.3.e through: (1) on-site treatment or treatment of a portion of the run-off for the project’s drainage areas with LID treatment measures at a joint stormwater treatment facility and treatment of the remaining run-off with LID treatment measures at an off-site project in the same watershed or (2) treatment on-site or treating a portion of the run-off for the project’s drainage areas with LID treatment measures at a joint stormwater treatment facility and paying an equivalent in-lieu fee to treat the remaining runoff through LID treatment measures at a regional project or a regional or municipal stormwater treatment facility that discharges into the same watershed as the project. The regional project must achieve a net environment benefit and must be constructed by the end of construction of a regulated project. If more time is needed, regional projects must be completed within three years after the end of construction of the regulated project and may be extended to a maximum of five years with prior Executive Officer approval.

The C.3 provision of the NPDES Permit also identifies incentive LID treatment reduction credits that apply to certain types of smart growth, high-density, and transit-oriented development projects or “special 1 The California Regional Water Quality Control Board San Francisco Regional Municipal Regional Stormwater NPDES Permit (Permit Number CAS612008), Final Order Number R2-2009-0074 is available online at:

projects” (as defined in Section C.3.eii of the NPDES permit) that, at the scale of the watershed, can reduce existing impervious surfaces or create less accessory impervious areas and auto-related pollutant impacts.

For any Special Project, the allowable incentive LID Treatment Reduction Credit is the maximum percentage of the amount of runoff identified for the Special Project’s drainage area, that may be treated with tree box high flowrate biofilters and/or vault-based high flowrate media filters. Projects within the WDSP area could potentially fall into one or more of these three categories of special projects that may qualify for LID treatment reduction credits:
▪ Category A projects may qualify for a 100 percent LID Treatment Reduction Credit – these projects are designed to be pedestrian friendly; create or replace less than ½ acre of impervious surface area; located in a downtown area,
neighborhood center, or other pedestrian-oriented district or historic preservation area; propose no or only incidental surface parking area; and propose at least 85 percent lot coverage. ▪ Category B projects may qualify for a LID Treatment Reduction Credit between 50 and 100 percent depending on their proposed lot coverage – these projects are designed to be pedestrian friendly; create or replace between ½ acre and two acres of impervious surface area; located in a downtown area,
neighborhood center, or other pedestrian-oriented district or historic preservation area; propose no or only incidental surface parking area; and propose at least 85 percent lot coverage. ▪ Category C projects may qualify for a LID Treatment Reduction Credit between 10 and 50 percent depending on their location and design – these projects are transit-oriented, non-auto related uses; designed to be pedestrian friendly; that would create or replace between ½ acre and two acres of impervious surface area; propose no or only incidental surface parking area; and propose at least 85 percent lot coverage.

In addition to the C3 permit provision, all construction projects in Suisun City are regulated by the NPDES General Permit for Stormwater Discharges Associated with Construction Activity, which requires the preparation of a Storm Water Pollution Prevention Plan and filing of a Notice of Intent with the State Water Resources Control Board for all project that disturb an area of one acre or greater.

Storm Drainage Pumps
The City has four stations that drain the areas within and discharge at locations described below:
▪ Downtown/Main Street. This station is located underneath the area where Sacramento Street enters the public parking lot, adjacent to the marina. This drains the area from Solano Street, 327
Chapter 5 | Open Space + Civic and Services

north to SR 12. School Street, west from Sacramento to the south, drains to another watershed. The Main Street pump station protects the northern section of the old downtown area and was just replaced this year as part of the downtown plaza. It now has a capacity of 8,500 GPM using two parallel submersible pumps. The station is controlled by a PLC using a bubbler system for level control. The calculated runoff is 4,100 GPM.
▪ Wildlife/Kellogg Street Pump Station. This station is located at the south end of Kellogg Street. It drains from Solano Street south, including the area above that drains down School Street. It pumps the water collected from the southern part of the old downtown area into the Suisun Slough. There is one main outlet into the Wildlife Channel, which is the School Street storm drain. The pump station and discharge line were replaced in 1997 with a submersible pump station, built next to the old station, and a new larger discharge line. The old pump, check valve, and MCC were removed and the old wet well and discharge line were left intact for possible future adaptation with a portable diesel pump for emergency use. The station includes a medium size detention basin allowing for some storage during short, high rainfall events.

The new station has a capacity of 4,600 GPM with one pump, 8,000 GPM with two pumps, and 9,900 GPM with three pumps.

Currently two pumps are installed with all piping and the MCC ready to accept a third pump. The calculated runoff is 7,800 GPM.
▪ Whispering Bay/Mulberry Street Pump Station. This is
located at the south end of the Whispering Bay Drainage Channel. It drains the area from Lotz Way and Main Street to Marina Boulevard, including all the residential streets within the area. There are multiple discharge outlets into the Whispering Bay Channel. The pump station has two independent propeller pumps with ultrasonic level controls. New discharge pipes and bar screens were installed in 1988. The estimated runoff is 15,700 GPM for a 6-hour event. He station was rebuilt in 2000 with capacity to exceed these flows. The station has a large detention basin allowing the required capacity to be lowered, if desired. ▪ Heritage Park Subdivision/Chipman Lane Pump Station.

There is a pump station along SR 12, about midway on Chipman Lane. This drains a large portion of the Heritage Park Subdivision.

The Chipman Lane pump station collects storm water in the north-south area between Chipman Lane and the railroad tracks and pumps it under SR 12 into a channel. The station has three independent propeller pumps controlled by float switches, with a total capacity of 30,300 GPM. The estimated runoff is 8,300 GPM.

5.2.4 Solid Waste
The City contracts with Republic Services Solano Garbage to provide weekly collection of solid waste, yard waste, and recyclable material to 328

5.2 Utility Services

October 2023 Page 5-17
the residents and businesses of Suisun City. As part of the statewide waste management and reduction policy, the California Integrated Waste Management Board (CIWMB) allocated the City of Suisun City with a disposal target of 4.9 pounds per person per day. In 2014, the City of Suisun City’s disposal rate was 2.6 pounds per person per day, considerably below the CIWMB target.

Suisun City has one recycling drop-off center located within the city boundaries. Recyclable material that is collected by Republic Services is sent to The Recyclery at Newby Island facility, located in Milpitas.

Solid waste collected from Suisun City is deposited at the Potrero Hills Landfill. In 2014, the landfill received 588,917 tons of solid waste, of which

2.3 percent was from Suisun City residents and businesses. The total capacity of the landfill is 55.865 million cubic yards. The landfill currently has a remaining capacity of approximately 33.815 million cubic yards. It is projected that the landfill will reach capacity in December 2045.

5.2.5 Gas and Electric
The Pacific Gas and Electric Company (PG&E) provides electricity and natural gas to the City. Public electrical energy for Solano County is generated outside the County and supplied via transmission lines. Major transmission line corridors traverse Solano County, serving the greater Bay Area. PG&E provides natural gas service to the area through both underground and aboveground transmission and distribution facilities.

New distribution facilities are typically constructed within easements on private property.

However, in some instances, new facilities are constructed within existing streets to increase capacity. Locations of distribution facilities generally depend on how and when an area develops. Specific Plan Area projects applicants and the City are required to involve PG&E in the development process to ensure that electricity and natural gas provision needs are incorporated into the development process.

5.2.6 Telecommunications
AT&T (formerly SBC), provides local telephone communication service for all of Solano County, including Suisun City and the Specific Plan Area.

Major telephone transmission lines traverse the region. These lines normally follow rights-of-way that parallel roadways and rail lines. AT&T also provides internet service in the area. Cable television service is provided through Comcast, Inc.
329
Chapter 5 | Open Space + Civic and Services

5.3 Community Services

5.3.1 Public Safety
Police protection is provided by the City of Suisun City Police Department, which is located in the Specific Plan Area adjacent to City Hall. The Suisun City Police Department currently has no plans to upgrade or reconstruct the police station or the Burdick Center substation outside the Specific Plan Area. However, there may be opportunities during implementation of the Specific Plan to use technology within the WDSP Area to enhance security, for example, through Bluetooth access for security communication or through the installation of emergency call boxes.

Fire protection is provided by the City of Suisun City Fire Department, which provides fire protection services in the incorporated area of the City. The Department has one fire station at 621 Pintail Drive and has considered alternative locations to better serve residents and address citywide goals to respond to 90 percent of all calls within five minutes.

The Department has a memorandum of understanding as a member of the County Hazardous Materials Response team and participates with the State Office of Emergency Services for mutual aid response agreements.

5.3.2 Educational Facilities
The Fairfield-Suisun Unified School District (school district) provides service to elementary, middle, and high school students. The Specific Plan Area is served by Crescent Elementary School, a K–5 school east of the Specific Plan Area and south of SR 12. Crystal Middle School serves students from grades 6-8 and is located within the Specific Plan Area, at the southeast corner of Driftwood Drive and Whispering Bay Lane. The Specific Plan Area is within the school boundaries of Armijo High School.

Solano County College is a community college in Fairfield that offers a variety of degree programs and serves the Suisun City area.

5.3.3 Library Facilities
There is one library serving Suisun City, the Suisun City Library, a branch of the Solano County Library system. This facility, which opened in 2008, is 10,000 square feet and is built adjacent to the Suisun Elementary school and doubles as a public and school library. The library includes a study room, community meeting room, and computer center. It hosts library programs during the day and community meetings at night. 330

CHAPTER 6| DEVELOPMENT + DESIGN

STANDARDS

6.1 Introduction
This chapter establishes the development and design standards governing proposed development within the Waterfront District Specific Plan (WDSP) Area (Specific Plan Area). When reviewing project plans, the reviewing body (Development Services Director, Planning Commission, or City Council, as the case may be) shall refer to the WDSP development and design standards. Where the WDSP is silent on an issue, the City will consult the General Plan and Zoning Code. If there is a conflict between the General Plan and the Zoning Code, the General Plan prevails.

A. Standards
Standards are identified by terms such as “shall,” “must,” “required,” or “prohibited.” Standards are specific and measurable regulations that are applied in the review of projects. Compliance with standards is required through the entitlement review process.

6.1.1 Community Design Approach
Development standards provide clear direction on the scale and location of new buildings constructed within the Specific Plan Area.

Design standards emphasize the creation of a sense of identity and orientation for pedestrians, residents, and visitors. This is accomplished by a variety of means, including through the scale, orientation, and design of the built environment; orientation and design of public spaces and landscaping; a grid street pattern; a visible hierarchy of streets; a comprehensive open space system; and other techniques.

Design standards for residential development apply to each of the residential Land Use Zones: Residential Low Density (RLD); Residential Medium Density (RMD); Residential High Density (RHD); and Historic Residential (HR). Please refer to Chapter 3 for a more detailed discussion of the Land Use Zones.

Design standards for commercial and mixed-use (residential and non- residential) development apply both based on the Land Use Zone of the proposed project.
331
Chapter 6 | Development + Deign Standards

6.2 Residential Development + Design Standards

6.2.1 Intent
Residential development and design standards focus on developing a traditional downtown setting that fosters community activities, social interaction, and a strong cohesive image for the Downtown Waterfront District. Design standards will maintain the pedestrian-oriented environment, where the fundamental intent is to reduce the impact of the vehicles by requiring narrower streets, smaller lots accessed by alleys and with opportunities for on-street parking and less off-street parking than allowed under conventional zoning standards. Old Town Suisun City is an inspiration for new residential development in the WDSP, with its smaller blocks and lots, grid pattern of streets, diverse architectural styles, and variety of housing types and sizes.

6.2.2 Residentia l Development Standards
Development standards for residential uses within the Specific Plan Area are summarized in Table 6-1. Existing uses and structures in established residential neighborhoods that are not in compliance with some of the development and design standards in this chapter shall be allowed to continue, but subject to the standards for nonconforming uses and structures described in Chapter 7.5.
▪ New residential lots shall have the minimum lot sizes and setbacks indicated in Table 6-1, except that porches, stoops, bay windows, balconies, and eaves and overhangs may encroach into setback areas, as indicated in the table below.
