Transportation Engineering & Design
The Transportation Engineering and Design (TED) Division is responsible for the design of various transportation related capital improvement projects. Our primary focus is pavement rehabilitation, striping, American Disabilities Act curb ramps, bike lanes, bike racks and sidewalk installation. Our division believes that Streets are a vital part of livable, attractive communities. Everyone, regardless of age, ability or income ought to have safe, comfortable and convenient access to community destinations and public places. Whether walking, driving, bicycling or taking public transportation, our goal in Transportation Engineering and Design is to provide "Complete Streets" with every project we design and build.

Transportation Sales Tax Information (Measure L)
The Stanislaus Council of Governments previously proposed an Expenditure Plan based on a 25-year, half-cent sales tax measure for consideration by voters on the November 2016 ballot called Measure L. This measure was passed and will move forward. The City of Modesto will use these website materials to keep you informed of their current projects associated with Measure L.
About Transportation Engineering & Design
Vision
Creating healthy, safe, efficient transportation and development. Modesto's network of roads, bike paths, lanes and sidewalks provides safe places for you and your family to get around. More of this network is being built each year, making Modesto a healthy, safe and connected community.
We strive to create a transportation network that more efficiently allows residents of Modesto to walk, bike, drive and ride transit to work every day. This "Complete Streets" mindset will create a balanced transportation system that provides safe and convenient facilities for all users and all modes of transportation.
Transportation Engineering and Design provides the administration and management of a full spectrum of engineering, transportation and development projects and services within the City, ensuring that infrastructure and expansion enhances the environment and quality of life throughout Modesto. Our goal is to design "Complete Streets" and encourage smart development that provides transportation choices in partnership with sustainable growth; this will create a healthy economically vibrant community.

- Bike Corrals - We, along with the Downtown Modesto Partnership, installed the first "Bike Corral" in the City of Modesto. It is located on the corner of 11th and J Street.
- Bike Racks - We install and maintain publicly accessible bike racks throughout the City.
- Complete Streets - We, working along with Urban Planners, design all road resurfacing projects with all users in mind. This complete streets mindset will ensure that the network gets completed.
- Curb Ramps - Every year hundreds of curb ramps are built, making it easier for those in wheelchairs and many others to move about in Modesto.
- Parklets - We, along with the Urban Design Group of the Downtown Modesto Partnership installed the first "Parklet" located at the corner of 10th and J Street.
- Safe Crossings - To increase safety and accessibility, we install median islands and crosswalks throughout Modesto.

What is a complete street?
A complete street is a transportation facility that is planned, designed, operated, and maintained to provide safe mobility for all users, including children, elderly, pedestrians, bicyclists, transit vehicles and trucks appropriate to the function and context of the facility. Every complete street looks different, according to its context, community preferences, the types of road users, and their needs.
Pavement Rehabilitation Treatments
Crack Treatments
Crack treatments consist of placing specialized materials into prepared cracks to prevent water and incompressible intrusion into the cracks and underlying pavement layers, and to reinforce the adjacent pavement. Restriction of water entry into underlying pavement base and sub-grade layers serves to maintain pavement strength and prolong pavement life. Pavements in different climate zones, with different construction types, and with different traffic loadings experience different types of cracking. The various crack types experience different movement ranges depending mostly on crack spacing and temperature variations. Different types of crack treatment materials and installation geometries are required for the different conditions.
Chip Seal
Chip Seal is an application of a bituminous binder covered with an application of clean graded aggregate to an existing asphalt surface. It is also known as armor coat, bituminous sealing or seal coat, to name a few. The binders may be emulsions, paving grade asphalt cements, and modified versions of each being modified with various polymers such as latex, tire and natural rubbers.
The aggregates commonly vary in size from a maximum of 5/8 of an inch to a minimum of ¼ inch with less than 5% passing the No. 4 screen. Aggregate must be durable with the use of crushed stone, gravels or manufactured aggregates. Aggregates may be pre-coated with a small % of asphalt cement when used with hot asphalt binders. Chip Seal has been used in various forms since at least the early 1900’s. The quality has improved over the years with better binder technology, cleaner aggregates, and improved equipment and a better understanding of how the materials perform together.
Slurry Seal
The principal materials used to create slurry seal are aggregate, asphalt emulsion, and filler, which are mixed together according to a laboratory’s design-mix formula. Water is also added for workability.
Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry surfacing to the old surface over which it is being applied. Various emulsions and aggregates are used to meet the conditions, specifications, and requirements of individual projects.
The aggregate must be clean, crushed, durable, properly graded, and uniform. The asphalt emulsion is a three-part system consisting of asphalt, water, and emulsifier. Fillers such as Portland cement, hydrated lime, or aluminum sulfate liquid are often used in small quantities as stabilizers or chemical modifiers.
Aggregate types:
I (fine)
- Fine aggregate mixtures are used for maximum crack penetration and sealing in low-density/low-wear traffic areas.II (general)
- Type II aggregates are the most commonly used and are widely employed where moderate-to-heavy traffic is found. They seal, correct moderate-to-severe raveling, oxidation and loss of matrix, and improve skid resistance.III (coarse)
Type III corrects severe surface conditions — preventing hydroplaning and providing skid resistance under very heavy traffic loads.
Micro Surfacing
One of the most versatile tools in the road maintenance arsenal, Micro Surfacing is a polymer-modified cold-mix paving system that can remedy a broad range of problems on today’s streets, highways, and airfields.
Like its parent product, slurry seal, Micro Surfacing begins as a mixture of dense-graded aggregate, asphalt emulsion, water, and mineral fillers. While conventional slurry seal is used around the world as an economical treatment for sealing and extending the service life of both urban and rural roads, Micro Surfacing has added capabilities, thanks to the use of high-quality, carefully monitored materials, including advanced polymers and other modern additives.
Pavement Overlay
An asphalt overlay is a new mat of asphalt applied to an existing concrete or asphalt surface. Typically, an asphalt overlay is 2 inches in thickness. As a rule of thumb, asphalt overlays generally last 10-12 years.
Mill & Fill Pavement
The concept behind mill and fill entails removing the existing surface layer with a milling machine and then transporting the material to a storage facility. New asphalt is then used to replace the milled location, adding 10 to 12 years of life to the road surface. Milling can also remove distresses from the surface, providing a better driving experience and/or longer roadway life.
