Castle Rock & Sierra Roundabout

City of Woodlake, CA

Castle Rock & Sierra Roundabout

The City of Woodlake constructed a single-lane roundabout at the Castle Rock Street and Sierra Avenue intersection. As the Woodlake community grew, the original intersection became congested with school, recreation, and residential traffic. This $3.1 million project was paid for by Measure R, CMAQ, and LSRP funds and included the roundabout, curb, gutters, ramps, sidewalks, streetlights, paving, on-street parking, landscaping, irrigation, sewer system, and storm drain improvements. 

The Castle Rock & Sierra Roundabout achieved the City’s objectives to relieve traffic congestion, increase bike/pedestrian safety, and provide adequate ADA accessibility. Added benefits of the project included improved air quality for nearby residents, park users, and elementary school students. Landscaping additions to the corners and center of the roundabout beautified the area for the growing number of residents and travelers who will pass through the intersection in the coming years. The City transformed an inadequate intersection into a roundabout that addressed basic transit needs while creating an aesthetic that reflects the City staff’s dedication to their community. 

Visalia Road Improvements Phase I

City of exeter, CA

Visalia Road Improvements Phase I


The Visalia Road Improvement Project Phase I consisted of road improvements between Jacob Place and Orange Avenue. The scope included the total reconstruction of the existing roadway, new curb and gutter, landscaped medians, entrances into businesses, sidewalk, signing and striping, and modifications to the existing signal at Belmont Road.  This $4.3 million was part of the City of Exeter’s sweeping Visalia Road Improvement Project that addresses community safety and operational needs. 

Years of wet winters and hot summers took a toll on the road’s original pavement, making it unpleasant for travel. The road was not fully ADA accessible and wasn’t inviting or conducive to pedestrian traffic, negatively impacting local businesses. The project design addressed each of these areas with added considerations for improving traffic circulation and providing a fresh, inviting thoroughfare through the City. The completed project met local and regional active transportation goals and will increase the economic viability of the area.

South Farmersville Boulevard Safe Routes To Schools Project

City of Farmersville, CA

South Farmersville


The City of Farmersville’s South Farmersville Boulevard Project is a pedestrian and bicycle improvement project, as well as a transit project. The Project improves pedestrian and bicycle safety by addressing deficiencies near places of employment, schools, and neighborhoods.

The Project’s location is South Farmersville Boulevard, the main north-south arterial in the City, and extends from just south of Visalia Road to the southern City limits, approximately ½-mile. The Project is in the direct vicinity of Snowden Elementary (approximately 450 students in grades 2 and 3). Roy Park and a senior housing community are also adjacent to the Project, as well as commercial and residential uses. A lack of contiguous sidewalks at this location forced students and others, including seniors, into the street or shoulder with no vehicular separation such as a raised curb. There were a narrow shoulder and no safe clearance for pedestrians or bicycles.

The Project included the design and installation of:

  • Approximately 1,700 linear feet of sidewalk
  • Five (5) ADA-compliant curb ramps
  • New pedestrian refuge median at the existing Snowden Elementary School crossing
  • Two (2) new transit stops
  • A new transit turn-around location
  • Signing; and Pavement Delineation
  • New Class II bicycle lanes

The existing Snowden Elementary School crossing was approximately 58 feet wide and vehicles typically travel between 35 and 45 mph in the area. The new pedestrian refuge median allows the students to cross half of the roadway and provides a safe area at which to remain before crossing the other half of the roadway.

There were previously no transit stops along South Farmersville Boulevard because the buses had no way to turn around. The project constructed a bus turnaround location which now allows for two transit stops on South Farmersville Boulevard. Seniors previously had to walk to transit stops on Visalia Road (approximately ½-mile) to travel to medical appointments, shopping, etc. With the new transit facilities adjacent to the senior housing community, it is much easier for the seniors to obtain transit service allowing them more freedom and independence.

QK provided engineering design and drafting, land surveying, utility coordination, right of way designation, environmental compliance, construction staking, and construction management and field observation services for the project.

Glaze Avenue

City of Exeter, CA

Glaze Avenue


The City of Exeter’s Glaze Avenue Project (Project) was a shoulder stabilization project which constructed approximately 31,000 square feet of pavement to provide shoulders along a mile-long segment of Glaze Avenue between Belmont Road and State Route (SR) 65 (Kaweah Avenue). Glaze Avenue is the southern-most roadway in the City of Exeter. A park, as well as residential, industrial, and agricultural uses, are adjacent to the Project. The roadway width was as narrow as 15 feet in some locations prior to construction.

The additional paving allowed for full-width, vehicle travel lanes, as well as shoulders striped as Class II bicycle lanes to provide bicycle connectivity across the southern end of the City. Project construction also included utility relocations, storm drainage, signing, and pavement delineation. The Project was funded by the Congestion Mitigation and Air Quality (CMAQ) Improvement Program, toll credits, and local funds.

South Valencia Boulevard Sidewalk Project

City of Woodlake, CA

South Valencia Boulevard Sidewalk Project


The South Valencia project was initiated by the Dolores Huerta Foundation in an effort to construct ADA improvements on the southern portion of the City that would provide a safe pathway for pedestrians, and school children.

QK provided engineering design, utility coordination, land surveying, right of way, construction engineering, CEQA compliance, and biological services for the South Valencia Sidewalk Project along Valencia Boulevard from Bravo Avenue to Deltha Avenue. Street improvements included the design of one half-mile of the curb, gutter, and sidewalk, seven (7) ADA accessible (ADA compliant) pedestrian curb ramps, two cross gutters, asphaltic concrete, 50 drive approaches, and tie-ins to meet ADA standards, new storm drain system, and signing and pavement delineation modifications. Additionally, 22 palm trees lining S. Valencia Boulevard and a small grove of eight eucalyptus trees were removed.

QK biologists conducted bat roosting surveys and eagle/raptor nest surveys of the project site to determine whether any bat species were present within the disturbance area of the trees. A survey was also conducted for the presence of any existing active or inactive raptor nests that may be used during the 2017 nesting season. During construction, QK is providing staking and field observation services for the project.

Garden In The Sun Park

City of Arvin, CA

Garden In The Sun Park


Creating recreational areas in the City of Arvin is essential for the quality of life and promotion of healthy living. In 2010, the City of Arvin was awarded a Proposition 84 Park Grant which provided the means to construct a new park in the center of the City. The 5-acre park is near the City’s proposed civic center and the Jewett Square mixed-use development. The park fronts the newly completed Walnut Street alignment –a big step to improving the traffic and pedestrian circulation within the project vicinity and connecting Arvin High School to the City’s main thoroughfare, Bear Mountain Boulevard.

QK assisted the City of Arvin in developing a comprehensive park project and construction plans incorporating proven sustainable solutions. Conceptual drawings and construction plans and specifications were prepared for the entire project.

The park’s design includes the following features:

  • Feature fountain at park’s main entry with decorative tile surfacing, seat walls, and planters
  • Large concrete entry plaza
  • Tot Lot (engineered wood fiber play surface and concrete curbs)
  • Splash pad (proposed for a later phase of development)
  • Restrooms building
  • Storage and equipment building
  • Gazebo with game tables and large concrete surface chessboard
  • Picnic arbors
  • Monument sign
  • Grass volleyball court
  • Loop trail, concrete walks, and nearby planter areas
  • Benches, picnic tables, drinking fountains, bike racks, and trash receptacles
  • Loop trail, concrete walks, and nearby planter areas
  • Benches, picnic tables, drinking fountains, bike racks, and trash receptacles
  • Drought tolerant plantings in the botanical garden
  • Mural walls at the west perimeter block wall
  • Exercise stations with DG (decomposed granite) surfacing
  • Site lighting
  • Safety bollards at park entry drop-off
  • Bio-Retention Cell for drainage
  • New water-efficient irrigation system for the entire park

The park’s ribbon-cutting ceremony took place on September 22, 2017, with a marching band, cultural dancing, and numerous food and specialty booths tucked between the stately palms on Walnut Avenue. Walnut Avenue was designed to be an extension of the park with community celebrations, farmers’ markets, art fairs, and other special events located on the newly opened street.

Hanford General Plan Update, EIR, Zoning Ordinance Update, Subdivision Ordinance Update & Infrastructure Master Plans

City of Hanford, CA

Hanford General Plan Update

Due in large part to the success of QK’s APA award-winning Hanford Downtown East Precise Plan and our team’s experience with the preparation of policy documents, the team of QK and Zumwalt-Hansen & Associates was selected to prepare a comprehensive General Plan (GP), Zoning Ordinance (ZO) and subdivision ordinance update, as well as the supporting environmental review/reports for the City of Hanford.

The purpose of a General Plan Update is to serve the City for the next 20 years, comply with state, local, and federal regulations, and provide the community with a vision for the City’s future, as well as guidelines for the way land will be developed and used. QK led the public outreach efforts and guided the discussion with the Citizen’s Advisory Committee and led several key discussions about the Citizens’ wants and needs for the GP. Those discussions led to actual policies in the GP.

Four important and distinctive features included:

  • Goals, objectives, policies, and programs for elements in land use and community design; transportation and circulation; open space, conservation, and recreation; health and safety; public facilities and services and environmental justice;
  • An extensive public engagement/outreach program including a city-wide bus tour and 14 meetings with the 20-person Citizen’s Advisory Committee;
  • Preparation of a program-level Environmental Impact Report (EIR);
  • A ZO update that reflected the City’s desire for a “Red Carpet, not Red Tape” approach.

Development of the GP and the ZO coincided with the construction phases for the California High-Speed Rail, recent State laws like Senate Bill 375, California’s Sustainable Communities and Climate Protection Act and regional planning efforts like the San Joaquin Valley Blueprint. The GP and the ZO reflect the new State laws as well as changes in housing preferences. The EIR was certified, and the General Plan and ZO were adopted by the City Council in April 2017.

As an extension of the GP/ZO update process, QK concurrently prepared the Infrastructure Master Plans for sanitary sewer, potable water, and storm drainage. By including these Master Plans into the scope of the overall project, infrastructure planning occurred simultaneously with the GP update process. This proactive strategy eliminated a problem that too often plagues cities; a GP update identifies areas for development, and then later it’s discovered that the City cannot efficiently provide services.

Throughout the project, QK also provided grant writing support in coordination with components of the GP. The grant writing team was successful in procuring nearly a quarter-million dollars of funding early in the process that helped reduce the need for using general funds to finance the GP update.

New Well, Tanks, Booster Pump Stations, and Pressure Sustaining Valves

City of Chowchilla, CA

New Well, Tanks, Booster Pump Stations & Pressure Sustaining Valves

The City of Chowchilla (City) faces challenges familiar to many California small and rural cities, which often serve disadvantaged communities with limited resources. City officials and staff in these communities put their hearts and souls into their service, and as we see here in the Valley every day, this type of leadership can lead to great advances that benefit the public far into the future.

Since a previous infrastructure analysis for the City showed significant deficiencies in its water system, the City knew it needed to make a big change. But thinking forward, it didn’t seem enough to the Council and Staff to simply put a band-aid on the structural problems. They didn’t want to just fix things that needed immediate repair. They wanted to commit to the delivery of energy-efficient infrastructure across the board so that their constituents would know that their contributions as ratepayers are being wisely invested in their long-term future, instead of short-term remedies.

It was this total commitment to water and energy efficiency that led City leaders to find Johnson Controls, Inc. (JCI), which was then able to assist City staff not only in planning for a clean and green future but with the creative financing of that plan that included public funding. Since City Council and Staff know that water is the lifeblood of their community, it was determined that an initial major step on the City’s path to sustainability should be in its water system.

The City has several aging wells and an elevated water tank that is no longer in use. Many of the wells have old equipment and controls that require constant attention and adjustments based on the seasonal water demands. The growing population and water demand of the City have only exacerbated the existing issues of insufficient well capacity, inadequate storage for peak hour and fire flow conditions, and the inability to pressurize the entire system.

The City is divided into two zones – the east and west sides of town, with HWY 99 running through the middle. Because the east side of town is positioned at a higher elevation than the west, the City was inundated with citizen complaints regarding the lack of pressure on that side.

So, when one of the City’s main wells went down, the long-awaited need for an updated system became urgent. As a result, the project design included drilling a new well and installing a 750,000-gallon storage tank at the City’s existing corporation yard that could be filled at night and pumped out during the day. The new well is equipped with a Variable Frequency Drive (VFD) which allows flexibility of speed at which the motor runs to adjust the flow rate of the well. A new booster station was also installed at this site, equipped with three VFD pumps that automatically adjust to meet the varying demand.

The design also included the installation of two Pressure Sustaining Valves (PSVs) – in the center of the two 12-inch main water lines that connect the east side to the west side. The PSVs only allow water to pass through in one direction unless certain pressure conditions are met. This ensures that the higher elevation side doesn’t lose pressure due to the water wanting to flow downhill.

Lastly, a solar panel array was installed on-site to not only provide power to the new facilities but some of the existing City buildings as well. In total, the combination of the new well, storage tank, booster pump station, PSVs, and solar panels ensure that the City’s water delivery system is operating efficiently, with the pressure necessary to satisfy the demands of its citizens, and the storage required to meet peak demands or to take the well offline for maintenance.

Cameron Creek Colony Emergency Water Supply Project

City of Farmersville, CA

Cameron Creek Colony Emergency Water Supply Project

The Cameron Creek Water project involved multiple agencies, groups, and individuals to get the project constructed without undue delay. It was a true team effort of the City of Farmersville, Tulare County Board of Supervisors, Tulare County Resource Management Agency, Tulare County Local Agency Formation Commission, Self Help Enterprises, Quad Knopf, Inc. (QK), and West Valley Construction. California State University Fresno and BSK provided additional support during the outreach and preliminary engineering, respectively.

QK provided the engineering design of 7,262 lineal feet of 8-inch water main, installation of 6 fire hydrants, 10 control valves, and 106 new water services to provide domestic water service to Cameron Creek Colony without an impact on Farmersville’s budget or without incurring a debt service that the severely disadvantaged community could not afford. Construction Management was also provided for the project.

On-Call Environmental Services

Panama-Buena Vista Union School District, Bakersfield, CA

On-Call Environmental Services

San Joaquin kit fox (SJKF) is an endangered fox subspecies native to the San Joaquin Valley region of California, and in the past, has burrowed underneath portable classrooms at district schools. QK works with the school district to obtain coverage under the Metropolitan Bakersfield Habitat Conservation Plan (MBHCP), to find the foxes a safe home. We also provide a districtwide SJKF awareness training program for students and staff and conduct protocol monitoring to identify SJKF activity and exclude kit foxes from atypical dens on school property.

By coordinating our efforts with the City of Bakersfield and associated wildlife agencies, we proactively identify issues as they arise, monitor SJKF activity, and help to create a safe environment for the students and staff, while protecting one of California’s indigenous species.
