As planners embark on finding the appropriate housing opportunity sites for the 6th Regional Housing Needs Allocation (RHNA), it is critical to consider the influence that climate change will have on these new developments, the public health and safety of future inhabitants, and the surrounding ecosystems. Although evaluating the impacts of climate change requires on-the-ground site assessment and thoughtful conversations with neighbors, businesses, and city leaders, there is an online planning tool that can help jumpstart your work in building resiliency into your new housing development decisions. The Bay Area Greenprint is the region’s premiere environmental assessment tool whose user-friendly features are highlighted in a previous post, Bay Area Greenprint - An Exciting and Efficient New Tool for Bay Area Planners. In fact, the Metropolitan Transportation Commission (MTC) has found the tool so useful that the agency is using the Bay Area Greenprint’s environmental data in their new Site Selection tool to assess the environmental viability of city and county housing opportunity sites, and you can too! 

The potential impacts of climate change and the plausible solutions to address global warming are all around us. The Bay Area Greenprint provides a one-stop-shop for climate data across several categories, including Carbon and Air Quality, Water, Agriculture, Urban Greening, and Wildlife that can be applied for both open space preservation and urban infill decisions. Understanding these opportunities and tradeoffs can provide planners with essential strategic direction when considering new development and conservation decisions for the 6th RHNA cycle. As jurisdictions continue to build out in accordance with their general plan, the edge areas of open space around the built-up areas offer a chance to conserve lands for resiliency against the effects of climate change from sea-level rise, for wildlife resiliency, and contribute to carbon sequestration. On the flip side, the infill opportunity sites across the region can play their part in making sure we are creating safe and healthy places for people to enjoy their urban lifestyles even under a shifting climate.

When evaluating the landscape for urban edge housing opportunities, perhaps you’ve wondered about the contribution of vegetation to sequester carbon dioxide and nitrogen oxide? Or you’ve heard the Sustainable Groundwater Management Act (SGMA) has recommended the evaluation of Groundwater Dependent Ecosystems to local groundwater management plans. These new and other Bay Area Greenprint layers can provide a quick evaluation for your project area to ensure new development plans prioritize preserving valuable ecosystems that will be more resilient towards mitigating the impacts of climate change.

Considering the quality of life for new residents is especially challenging to predict under a warmer climate. However, the Bay Area Greenprint offers recommendations to help planners prioritize tree planting to address the urban heat island effect and mitigate air pollution. It can also ensure new development plans incorporate access to parks, bike lanes, and regional trails. Having easy access to outdoor amenities in every neighborhood can help foster community and promote more active and healthy lifestyles as well as reduce automobile emissions. Another important layer in the tool helps inform planners and developers about the threat posed by environmental gentrification that occurs when the urban amenities you plan for in a neighborhood end up leading to the displacement of the existing residents you were trying to help.

This information and much more is just a click away in Bay Area Greenprint! It was created to be a ‘living tool’ that responds to the needs of users and will continue to play this role in the future. Your feedback, thoughts, and recommendations go a long way towards helping other planners with the same questions you’re wrestling with. To learn more about how to take advantage of this free easy-to-use tool, check out the recent Bay Area Greenprint webinar.

A great opportunity is available to California cities and counties through November 30, 2019.  The Department of Housing and Community Development, “HCD,” is offering a non-competitive grant to accelerate housing production through encouraged Priority Policy Areas.  Cities and counties can request up to $160,000; $310,000; or $625,000 depending on their recorded populations of less than 60,000, between 60,001 to 199,999 or over 200,000 respectively.  Grant monies have been gathered through a $75 real estate transaction fee enacted by State Bill 2 in 2017.

Cities and counties may use the funds for a wide variety of activities such as updates to plans or zoning ordinances, planning and building process improvements (including new permit software), and new ordinances that allow for by-right housing permits or objective design standards.  Applications that focus on Priority Policy Areas will require less paperwork and possibly have a shortened review time after submittal. 

Another aspect to note is the minimal requirements for official reporting.  These SB2 grant applications only require one report at close-out to trigger reimbursement of the funds, which must be spent by June 30, 2022.  At the conclusion of each project activity, jurisdictions can submit funding reimbursement requests to HCD.  Entities that are concerned about internal funding availability may incorporate several smaller projects into one application to allow for earlier multi-part reimbursements.

APPLICATION COMPONENTS

Cities and counties wishing to apply for SB2 grant funding must have an HCD-compliant housing element and have submitted Annual Progress Reports for 2017 and 2018.  Once these pieces are in place, applications must include a list of application activities, certification that these activities fall under State or Other Planning Priorities, a project narrative and a budget.  A standard resolution authorizing staff to enter into a contract with HCD must be ratified before the application deadline. “The application must demonstrate a significant positive effect on accelerating housing production through timing, cost, approval certainty, entitlement streamlining, feasibility, infrastructure capacity, or impact on housing supply and affordability.”

Priority Policy Areas:

(a) Rezone to Permit By-right housing;

(b) Objective Design and Development Standards;

(c) Specific Plans or Form based Codes Coupled with CEQA Streamlining;

(d) Accessory Dwelling Units (ADU) or Other Low-Cost Building Strategies;

(e) Expedited Processing;

(f) Housing Related Infrastructure Financing and Fee Reduction Strategies.

 

State Planning Priorities:

1) Promote Infill and Equity

2) Promote Resource Protection- ag lands, natural lands, recreation lands, locally unique landscapes

3) Encourage Efficient Development Patterns

 

Other Planning Priorities:

4) Affordability and Housing Choices

5) Conservation of Existing Affordable Housing Stock

6) Climate Change/ Climate Adaptation – flood, fire, vulnerable populations

 

NEXT STEPS

Given the short timeframe for application submittal, focusing on the adoption of HCD’s standard resolution at the City Council or Board of Supervisors and on determining project focus is key.  The application paperwork is not overly complicated, and HCD has indicated a desire to work with cities and counties toward mutually indicated goals (through an “over-the-counter process”).  Once this initial non-competitive grant round has ended, HCD has the option to open a new round of applications that would be competitive for remaining funds. Don’t miss out on this chance for funding for your city’s or county’s projects.

M-GROUP planners are well-versed in the SB2 grant process, having provided support for the following grant applications:

·         City of Cotati: $160,000 funding approved

·         City of Sebastopol: $160,000 in process

·         County of San Benito: $160,000 in process

·         City of Petaluma: $310,000 application in process

California experienced one of the most devastating wildfire seasons in 2017, with a total of 7,117 fires burning 505,956 acres. The fires in Sonoma and Napa counties burned 146,647 acres and destroyed nearly 8,000 structures in October, accounting for approximately 30 percent of the acreage burned in 2017. The fires in Ventura, Santa Barbara, and Los Angeles counties burned 303,561 acres and destroyed 1,120 structures in December, and accounted for approximately 60 percent of the acreage burned in 2017.

California is at great risk from wildfires because of its particular combination of weather, topography, and native vegetation. Southern California has the added risk of the Santa Ana winds that appear in the spring and late fall. Fire risks have increased with drought conditions, population growth, and increased development within the wildland-urban interface.

This article describes the various entities that are responsible for identifying and managing wildfire risk in California in order to minimize the loss of life and property from wildland fires in the future.

State-level Responsibilities

The California Department of Forestry and Fire Protection (CAL FIRE), State Board of Forestry and Fire Protection, and the California Building Code serve as the building blocks for identifying and managing wildfire risk at the state level.

CAL FIRE Mapping

CAL FIRE is required by law to map areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. CAL FIRE’s Statewide and County maps (adopted November 2007) depict Fire Hazard Severity Zones (FHSZs)[1] that are within the State Responsibility Area (SRA). The SRA identifies where the State of California is financially responsible for the prevention and suppression of wildfires. The SRA does not include lands within city boundaries or in federal ownership. The FHSZs in the SRA are further classified as being Moderate, High, or Very High.

[1] The FHSZs identify fire hazard, not fire risk. “Hazard” is based on the physical conditions that give a likelihood that an area will burn over a 30 to 50-year period without considering modifications such as fuel reduction efforts. “Risk” is the…

[1] The FHSZs identify fire hazard, not fire risk. “Hazard” is based on the physical conditions that give a likelihood that an area will burn over a 30 to 50-year period without considering modifications such as fuel reduction efforts. “Risk” is the potential damage a fire can do to the area under existing conditions, including any modifications such as defensible space, irrigation and sprinklers, and ignition resistant building construction which can reduce fire risk.

In addition, CAL FIRE has prepared recommendations for Very High FHSZs in those areas where local governments have financial responsibility for wildland fire protection, known as Local Responsibility Areas (LRA). Only lands zoned as Very High FHSZ are identified within the LRA. In 2008, CAL FIRE transmitted those recommendations to all local agencies with identified Very High FHSZs. However, this process has its limitations. First, because CAL FIRE only transmits the areas identified as Very High FHSZs to the local agencies, there could be some Moderate or High FHSZs within the LRA that are not being identified. Second, the CAL FIRE zoning designations do not go into effect until they are adopted by ordinance by local agencies. Last, the maps were created in 2008 and reflect outdated information. CAL FIRE is currently in the process of updating the FHSZ maps (Feb 2018).

pic2.jpg

Currently, CAL FIRE is investigating methods for estimating the likelihood of fire occurrence across the State in the coming decades. As part of this effort, CAL FIRE has created a map of annual fire probability for the period 2026-2050. This map is intended for use in the quantification of GHG benefits of fuel reduction activities funded under the 2016-17 Greenhouse Gas Reduction Fund Forest Health Program

Strategic Fire Plan for California

The 2010 Strategic Fire Plan for California (revised April 2016) was developed by the State Board of Forestry and Fire Protection and CAL FIRE. The plan’s vision is to support a natural environment that is more resilient and ensure that man-made assets are more resistant to the occurrence and effects of wildland fire. The plan identifies goals and objectives that are critical to reducing and preventing the impacts of fire, which revolve around both suppression and fire prevention efforts.

The first goal of the plan relates to the identification and evaluation of wildland fire hazards and recognizing the life, property and natural resource assets at risk. One of the objectives under this goal is to provide regular updates to the Very High FHSZ maps. Another objective under this goal is to update existing data for values and assets at risk utilizing GIS data layers and other mapping solutions.

California Building Code

To help manage wildfire risk at the state level, the California Building Code (CBC) contains standards for building materials, systems, and or assemblies used in the exterior design and construction of new buildings. For example, the 2016 CBC establishes minimum standards for the protection of life and property by increasing the ability of a building located in any FHSZ within SRA or any Wildland-Urban Interface Fire Area to resist the intrusion of flames or burning embers projected by a vegetation fire. (A Wildland-Urban Interface Fire Area is a geographical area identified by the state as a FHSZ, or other areas designated by the local agency to be at a significant risk from wildfires.)

However, the 2016 CBC standards have limitations. The standards only apply if: 1) the building site is located on land designated as a FHSZ or as a Wildland Interface Fire Area; and 2) the application for the building permit was submitted on or after July 1, 2008. Therefore, these standards do not apply to structures located outside of these designated areas. Additionally, these standards do not apply to structures for which building permit applications were submitted prior to July 1, 2008, regardless of their designation.

Local-level Responsibilities

Local agencies are responsible for identifying and managing wildfire risk within their jurisdictions. Cities and counties have multiple tools at their disposal to reduce wildfire risk, such as the General Plan, zoning ordinance, California Government Code, local fire departments, and Hazard Mitigation Plans. With new levels of concern regarding wildfires, local jurisdictions can evaluate their General Plans and zoning ordinances to locate weaknesses and bolster mitigation strategies related to wildfire hazards. Local jurisdictions can also create overlay zoning or overlay districts for areas prone to wildfires that mandate heightened development regulations and landscape wildfire mitigation compliance measures.

Local jurisdictions may rely on the support of regional agencies, such as the Association of Bay Area Governments (ABAG), which runs the Resilience Program to support local governments in planning for wildfires and other natural hazards. ABAG’s Mitigation and Adaptation Plans project supports the ongoing development of hazard mitigation and climate adaptation plans at the local level.

In addition, local government agencies receive guidance from State agencies, such as CAL FIRE and the State Board of Forestry and Fire Protection. The local government agencies can then implement recommendations through the enactment of ordinances. However, it is ultimately the responsibility of the local agencies to identify and manage wildfire risk within their jurisdictions.

Individual-level Responsibilities

In order to reduce risks associated with wildland fires at the individual level, California Government Code Section 51182 identifies specific strategies to be undertaken by a person who owns or leases an occupied dwelling or structures in, upon, or adjoining a mountainous area, forest-covered land, brush-covered land, or land within a Very High FHSZ. Strategies include maintaining defensible space around the structure, removing dead portions of trees near structures, and maintaining the roof clear of leaves, needles, or other vegetative materials. As stated in the California Government Code, local agencies having jurisdiction over the property can provide oversight to ensure that these mitigation strategies are implemented.

Conclusion

Wildland fire is a natural part of California’s landscape. The responsibility for identifying and managing wildfire risk in California is shared by the State, local jurisdictions, and individual property owners.

As a starting point, areas of significant fire hazards must be accurately mapped, routinely updated and property owners informed of risks. Local jurisdiction must impose restrictions through their land use regulations and long-range planning efforts to ensure that high risk areas are protected. Individual property owners must maintain defensible space, remove dead portions of trees, and keep roofs clear of vegetative materials.

Moving forward, dialogues will continue to take place within communities to identify wildfire-related risks and propose actions to reduce these threats. These discussions will propel local communities towards their own solutions to prepare for and reduce wildfire-related risks.

Cottage Housing Developments

by Justin Shiu, Associate Planner at M-Group


Cottage housing developments, as a form of smaller single family residential units, diversifies housing choice and provides housing that is more attractive to some households than that of traditional single-family homes.

The type of cottage housing development discussed here refers to projects that feature a cluster of units – often between four and twelve – built around a common open space. Typically, each cottage is around 1,000 square feet. This type of development is not new; the historical pattern of small housing units clustered around small parks and open spaces can be found in some parts of older cities. Recent cottage housing developments have been established as infill projects, offering a middle ground between single-family residences and multifamily development. Cottage housing can offer a smaller scale housing choice, which are suitable for meeting a variety of needs, compared to traditional detached single-family homes.

Cottage housing developments can be found around the county. They present a variety of opportunities in creating housing and meeting housing needs where other prevalent housing types are not great fits. There may be challenges implementing cottage housing developments where development constraints or local opposition limit available options. To create opportunities that allow for cottage housing development and set standards for development, a variety of considerations should be taken into account in the planning process. The following presents a brief overview of cottage housing development and provides considerations for their integration into cities.


COTTAGE HOUSING DEVELOPMENTS AROUND THE COUNTRY

Cottage housing developments can be found around the country. In Shoreline, Washington, Greenwood Avenue Cottages features eight units of less than 1,000 square feet around a large open space and served by a 300 square foot community building. Beyond offering attractive, smaller housing options for those drawn to their style, cottage housing developments have served needs for different segments of the population.

Cottages have been suitable for providing workforce housing. In Suffolk County, New York, Cottages at Mattituck is a 22-unit income-restricted workforce housing project. The price for the 1,100 square foot units was determined by median income earnings. The cottages will remain permanently affordable through deed-restrictions.

Cottages can be affordable options integrated into an urban context. In East Greenwich, Rhode Island, Cottages on Greene is a privately-financed, mixed-income infill development located in the historic downtown area. The cottage housing style emphasized a walkable and smaller-scale, urban living environment. This denser residential development type serves as a transition between the downtown and single-family residences and allows for locating 15 homes within walking distance to a variety of shops, services, and restaurants in the downtown. The project also allocated five deed-restricted affordable housing units.

Cottages can be important residences for groups with special circumstances. In Sacramento, Quinn Cottages is an affordable development comprising 60 one-bedroom cottages serving single residents and parents with one child. Mercy Housing manages the cottages and provides support programs that allow the development to serve as transitional housing.


OPPORTUNITIES AND ADVANTAGES

The appropriateness of cottage housing developments may vary depending on the location, however the developments can have advantages over other types of development. They can make more efficient use of land than single-family residential development. Although they are denser than traditional single-family homes, cottage housing could be implemented in single family residential areas where the cluster of housing would not appear to be a significant departure from an already dense concentration of single-family homes, or a medium-density single-family residential district as applied in some jurisdictions. They can fill properties that are large and underdeveloped. While developments may have densities somewhat higher than neighboring single-family homes, design of the buildings and the common open space can minimize the perception of mass. They may also serve as a transition between single-family homes and condominiums / townhomes.

As an intermediate between lower and higher density development types, a cottage housing development may help diversify housing choices and capture needs from different segments of the population. Cottage housing offers living arrangements that are attractive to households seeking modestly-sized homes and those who desire a close neighborhood environment. This housing type is an option that can accommodate smaller households, including single residents, households with few children, and older residents seeking to downsize. The close proximity of units can lend itself to fostering a neighborhood within a neighborhood feeling, which can create a greater sense of familiarity and safety.

An advantage of cottage housing developments is their flexibility, from making more effective or desirable use of underutilized spaces to serving the needs of different populations. As an infill type development, they can maintain a spacious feeling with open courts. As higher density development, they offer privacy by having detached units. Their sizes allow them to be potentially more energy-efficient compared to larger residences. They can serve as housing for families seeking to downsize, young households, and the workforce.

CHALLENGES

Although cottage housing developments can present a number of opportunities, they may be accompanied by specific issues due to characteristics of the development.

Construction is not necessarily much less expensive than traditional single family homes. The baseline standards of the cottages are the same for new residences, including compliance with building standards and installation of utility connections. Furthermore, costs for cottages may be more on a per-square-foot basis because unit prices cannot be increased based on square footage with as much bedroom and living room floor area that can be relatively inexpensive to build.

Locational suitability is a limiting factor. Availability of lots with sizes capable of accommodating development may be low. Allowable density on a lot generally needs to be higher to allow for economically feasible projects. However, neighborhoods may be sensitive to denser development. Taking lot size, density, neighborhood sensitivity into account, cottage housing developments may be limited to certain residential areas.

Parking can also present challenges. The site may have limited space available for parking. Despite smaller households that are drawn to cottage housing, sufficient parking is required to mitigate excessive spillover to on-street parking.


CONSIDERATIONS IN DEVELOPMENT STANDARDS

If it has been determined that a cottage housing development would not be impractical as a result of various challenges, a set of guidelines may serve to help shape how a development might fit within the site context. Cottage housing ordinances have been established in several jurisdictions. Ordinances that were reviewed include Kirkland, Spokane, Port Townsend, Redmond, Lakewood, and Marysville in Washington, and Lehigh Valley in Pennsylvania.

Although a cottage housing ordinance may not necessarily be a tool that every jurisdiction would want to consider integrating into their municipal codes, the examples of existing cottage housing development regulations provide a basis to review and evaluate cottage housing projects proposed within a community. The guidelines presented here do not represent a comprehensive collection of standards that have been used nor do they suggest that cottage housing design must fit within these parameters, but they present a starting point to consider what aspects of development have been applied and provide an initial point of reference for further discussion.


Units and Lot Sizes

  • Number of Units: A minimum and maximum number of units may be defined. Minimums of 4 units and maximums of 12 units have been used in some ordinances.
  • Lot Sizes: Consider not setting a minimum lot size.


Floor Area and Coverage

  • Density – Floor Area Ratio: The use of floor area ratio for a site may be an appropriate standard to allow a practical design of cottage housing development. If density is used, the standard may limit density to two or three times the density of base zoning, which also may vary based on the zoning district.
  • Floor Area: A maximum floor area may be set for each cottage housing unit. Example maximum floor areas have been found to be between 800 and 1,500 square feet.
  • Coverage: Coverage is applied on a per unit basis. Building coverage has been found to be between 40 and 60 percent.
  • Density: Increasing density may be accomplished through the following
    • Increasing density based on underlying zoning (e.g., base zoning multiplied by two)
    • Reducing minimum lot requirements (e.g., base zoning divided by two)
    • Multiple cottages on a lot (e.g., up to two cottages on a single family lot, with certain conditions)
  • Density Bonus: Consider the appropriateness of density bonus incentives.
  • Expansion Restricted: Covenants may be used to restrict the expansion of cottages.


Setbacks and Height

  • Setbacks: Consideration should first be given to the appropriateness of existing setback regulations. For setbacks different from standard residential zoning, the following have been used:
    • Front setback examples. 10-20 feet.
    • Side setback examples. 5-10 feet.
    • Rear setback examples. 10 feet.
  •   Average Setbacks: Consider using average side and rear setbacks to provide design flexibility
  • Building Separation: Use a minimum building separation to allow for space between buildings. A typical standard is 10 feet between buildings. Building code standards may be used to guide the minimum separation standard.
  • Stories: Consider whether a one story limit or a two-story limit is appropriate.
    • Some architectural styles of cottages featuring lower plate height accommodate second floor area within the roof. To limit mass, a cap on second floor area may be based on a percentage of the first floor.
  • Height: Consider whether development would create tall and overly narrow homes.
    • Pitch limitations on cottage roof.
    • Maximum ratio of height to width.


Parking

  • Parking Spaces: Off-street parking may be between 1.0 and 2.0 spaces per unit.
  • Parking Arrangement: Parking can be designed such that access is away from primary streets. Parking spaces design could be through side access by alley, side access by private street, and a non-primary street. Adequate screening should be provided for any option. Parking lots may be more feasible than individual garages.
  • Parking Clusters: Consider whether parking should be distributed among small clusters on the site to minimize visual impact. Consider maximum contiguous spaces in each cluster and minimum separation between clusters.
  • Parking Reduction: Parking reduction may be considered if the site is close to transit.

 
Design

  • Design: Consider whether requirements should be placed on a color scheme and variety in design.
  • Orientation: Orient the primary entry towards the common open space area.
  • Porches: Consider covered front porches. The minimum area may be 60-80 square feet.
  • Sidewalk: Sidewalk connections and sidewalks along public streets.
  • Parking Lot: Parking may be consolidated into one or a few small lots to allow for closer spacing between buildings.

 
Common Space and Amenities

  • Common Open Space Area: Each dwelling unit should provide an allotment of space for a common open space area. In several ordinances, 400 square feet per unit has been used but areas as small as 150 square feet per unit have been applied as well. Common open space may also be low in instances where there is a requirement for private open space.
    • Consider specifying that required setbacks, private open space, stormwater management facilities, parking areas, and driveways do not qualify as common open space area.
  • Community Building: A community building may be permitted.


Integration into the Community

  • Outreach: Provide outreach and education
  • Trial Period: Consider a trial period to ensure regulations are working as intended
  • Conditional Use Permit: An administrative conditional use permit may be a good approach to consider developer and community input so that the project works within the context of certain areas.


CONCLUSION

Cottage housing developments offer opportunities to fill in housing needs, but they may be limited in locations that could accommodate such developments. Density and neighborhood sensitivity may make it difficult to find suitable sites for cottage housing developments, in addition to needed interest from the developers.

However, it is also the compact character of these developments that makes them attractive to those with specific housing needs that can be served by small but detached housing units. In planning for cottage housing developments, establishing guidelines may help address some concerns related to the form the developments may take. A consideration of policies and guidelines can show if cottage housing developments would fit within the local context and how development may take shape.

How Millennials Will Shape the Future of Complete Streets

by Sheldon S. Ah Sing, AICP, Principal Planner at M-Group

Introduction

Complete streets are streets designed to accommodate all users, of all ages and abilities, and implementation of complete streets have provided a number of benefits within the community. In the past, the primary emphasis in street design was on the speedy movement of motorized vehicles along the right-of-way. The complete streets idea is based on the concept that a balanced, multi-modal transportation network would make the most efficient use of transportation infrastructure, serve to reduce greenhouse gas emissions and improve public health by encouraging physical activity through shifting short trips from driving to biking, walking and public transit. Since the implementation of complete streets, in addition to promoting healthy communities, it has also been found that complete streets have the effect of supporting local businesses and encouraging economic development. Communities have realized that implementing complete streets that foster multi-modal activities such as walking, bicycling and transit usage provide a wide range of benefits to employees, visitors and residents that make their community a desirable place to work, visit and live.

Millennials, the generation generally categorized as being born in a timeframe between the late 70s and 2000, grew to a population of 78.6 million in 2010, surpassing baby boomers as the largest demographic cohort in U.S. history. This generation’s preferences are changing the way products are advertised and how they are consumed and their lifestyle preferences are changing the way built environments are developed.

This article summarizes the benefits of complete streets, the importance of public investment in complete streets to spur private investment and the importance of thinking beyond downtowns and implementing complete streets in suburbia to account for the trends of millennials, the emerging demographic cohort entering the housing market.

 

Complete Streets Approach

The National Complete Streets Coalition states that “Complete Streets are streets for everyone”. Effective planning for complete streets balances allocation of space within the right-of-way to provide safe and effective infrastructure that can be used by all transportation modes and users. Effective complete streets empower users of all ages and abilities to safely move along and across streets in a community. By planning for a broad population, the approach brings together advocates and stakeholders from many different interest groups including older people, public health agencies, transportation engineers, bicycling and walking advocates, local business supporters and other interested people. Furthermore, complete streets policies can be written to support a broad range of community goals.

Typical complete streets improvements include:

  • Narrow travel lanes and seek opportunities to put streets on a road diet. For example, the conversion of a four-lane undivided road to a three-lane road with bike lanes (two-way left-turn center lane, two automobile travel lanes, and two bike lanes). This configuration can handle up to 18,000 Average Daily Trips (ADT) and improves safety and access to adjacent destinations.
  • Tighten corner curb radii to the minimum needed to provide a usable turning radius for an appropriately selected design vehicle. Occasional encroachment by larger vehicles into other travel lanes is acceptable; intersections should not be designed for the largest occasional vehicle.
  • Eliminate unnecessary turn lanes at intersections. Eliminating free-turning right turns or right turn lanes with fewer than 100 turns per hour.
  • Replace painted channelization islands at intersections with raised islands. This gives pedestrians a true place of refuge and breaks up long crossing of many lanes into smaller segments.

 

California Context

In 2008, the State of California adopted the California Complete Streets Act that required cities and counties to incorporate complete streets policies within their circulation elements upon any substantive revision to the general plan element. Complete streets policies plan for a balanced, multi-modal transportation network that meets the needs of all users of the streets, roads and highways, defined to include motorists, pedestrians, bicyclist, children, persons with disabilities, seniors, movers of commercial goods, and users of public transportation, in a manner that is suitable to the rural, suburban or urban context of the general plan.

 

Benefits of Complete Streets

A study by Smart Growth America published in 2015 reviewed 37 complete streets projects across 31 cities in 18 states and summarized the benefits of investing in complete streets projects. While limited in data and far from conclusive, the case study points to some very encouraging themes. It showed that complete streets projects improved safety, increased biking and walking, and resulted in mixed outcomes regarding increased and decreased vehicular traffic depending on the project goals.  In part, this mixed-result is because of differing methodologies employed in gathering the data, however, nonetheless, based on the available before-and-after data, regardless of vehicular information other key indicators had positive correlation with complete streets resulting in benefits.

Implementing complete streets can alleviate the problems created by existing auto-oriented streets. Auto-oriented streets are less safe because of higher speed limits, large widths, and inadequate sidewalks and crosswalks.  The case study demonstrated that decreasing the number of lanes and adding crosswalks, bike lanes and a center turn lane can result in reduced speeding, collisions and injuries. The same study indicated that in most instances pedestrian activity increased along with bicycle trips. Complete streets projects have also shown to have a mostly positive increase on public transit use. Walking is the most common way to access public transit and complete streets strategies can be used to complete the last mile on either end of the transit trip. Complete streets help create environments that led to increases in walking, biking, and transit use.

Local businesses see many benefits in improving access to people traveling by foot or bicycle. When a bike lane was added along Valencia Street in San Francisco’s Mission district, nearby businesses saw sales increase by 60 percent, which merchants attributed to increased pedestrian and bicycle activity (Smart Growth America, Complete Streets Spark Economic Revitalization).

 

Funding and Role of Public Investment

The hallmark of complete streets projects is that the project uses the existing right of way. There are no acquisition costs, and the typical improvements for complete streets is minimal. Complete streets projects cost less than conventional roadway improvement projects. On average a complete streets project costs $2.1 million (Smart Growth America, Safer Streets, Stronger Economies). These projects also cost less per mile than average arterial roadway projects. The Federal Highway Administration estimates that construction of an average “normal-cost” urban arterial costs $3.58 million per mile, and average “high-cost” arterials cost $12.75 million per mile.

In the mid-90s, the City of Portland spent $60 million and built 300-miles of bicycle infrastructure (lanes, paths and boulevards). For this modest investment, between 1990 and 2008, bicycle trips increased by 400 percent, while driving alone decreased by four percent and there were no bicycle fatalities. For the same investment, the City could have constructed one mile of a four-lane freeway. The results in Portland suggest that a fractional investment can lead to changes in travel behavior and safety.

Implementing complete streets projects can leverage future funding opportunities, since multi-modal projects are more competitive than singular-modal projects.

Public spending can spur private development

The investment that communities make in implementing Complete Streets policies can stimulate far greater private investment, especially in retail districts and downtowns where pedestrians and cyclists feel unwelcome. In Washington, D.C., design improvements along a three-quarter mile corridor in Barracks Row, including new patterned sidewalks and traffic signals, helped attract 40

new businesses and nearly 200 new jobs. The area experienced increases in sales and foot traffic. In Mountain View, California, the addition of space for sidewalk cafes and a redesign of the street for pedestrians were followed by private investment of $150 million, including residential, retail and offices, resulting in a vibrant downtown destination.  This provides evidence that the street and the land use work together and determine whether a place is attractive and draws people and investment and high-quality land uses come to high-quality streets.

 

Suburbia and Millennials

A desire for more walkable environments is growing among the younger population seeking housing opportunities. Millennials, the generation generally categorized as being born in a timeframe between the late 70s and 2000, grew to a population of 78.6 million in 2010, surpassing baby boomers as the largest demographic cohort in U.S. history. The idea of millennials living mostly in amenity-rich apartments in downtowns is not completely accurate. An Urban Land Institute report found that many millennials are living in less centrally-located but more affordable neighborhoods and sharing space with parents or roommates to save money. In summary this study found that:

  • Only 13 percent of millennials live in or near downtowns; 63 percent live in other city neighborhoods or in the suburbs.
  • Fifty percent are renters, paying a median monthly rent of $925.
  • Twenty-one percent live at home, but 90 percent expect to move out within five years.
  • Fourteen percent live in households with three generations of family members.
  • Eighteen percent of all millennials and 27 percent who rent share housing with roommates. However, 58 percent of those with roommates would prefer to live alone.
  • Virtually all expect to own a home eventually.
  • Nine out of ten expect to match or exceed their parents’ economic circumstances.

According to the study, “millennials expressed a higher level of dissatisfaction with their communities and local housing options than did [people in] other demographics”. Moreover, the study continues “they say that neighborhoods lack convenient outdoor spaces to run, walk, bike, and exercise. In addition, they believe that both traffic and crime make it unsafe to walk.” More than 60 percent of millennials, want to live in areas where they can use their cars less.

The preference for walkable neighborhoods is likely to increase in coming decades, too, as today’s young college graduates flock to downtowns and close-in suburbs. The population of college-educated 25 to 34 year olds in these walkable neighborhoods has increased by 26% in the last decade, creating a workforce that can further add to economic growth in these communities (ibid).

This cohort will eventually marry and have a family then seek housing appropriate for that lifestyle. Downtown living is expensive and unaffordable and suburbs alternatively provide the type of housing and affordable that would match the desires of millennials in the future. Whether they are in downtowns or in the suburbs, there will be a demand for more walkable places.

Suburbs

Much of suburbia will have to change in order to thrive and meet the health, environmental, and economic challenges of the coming decades. Because of their form, widely separated land uses, and disconnected street networks, most suburban areas lack walkability and require that people travel by car for most of their needs. Demand from millennial preferences are making it desirable to retrofit these communities with complete streets to meet the needs of the changing demographics.

The primary challenge in retrofitting suburbia is less fixing the infrastructure and more creating economically sustainable places, with the emphasis on place.  Not only streets will need to change in suburbia; many land uses are obsolete and/or no longer economically viable. Street improvements generally should come before land use change in suburban retrofitting. This is because high-quality land uses come to high-quality streets and that generally means more economic benefits. The street and the land use work together determining what is attractive and draws people and investment. The following should be considered when retrofitting suburbs:

  • Focus new investment in nodes on streets. There will not be enough investment all at once to transform entire corridors.
  • Focus revitalization efforts on creating genuine places in those nodes: compact, mixed-use, transit-oriented, and at least internally walkable. Plan for and enable neighborhood-serving commercial districts rather than automobile-serving uses.
  • Carefully detail the desired outcomes. It is important that retrofit efforts follow through desired outcomes such as reduced vehicle miles travelled, reduced greenhouse gas emissions and increased transit and bicycle ridership.

Conclusion

The complete streets concept provides an economically effective way to improve health, economic development, transportation efficiency and safety for communities. It has been proven that complete streets work in urban downtown areas. The same complete streets principals can be used to retrofit suburban infrastructure. This would be necessary to accommodate the future demands of housing for the next generation.
