Project Organic, a TIRZ Master Plan commissioned by the Harlingen EDC, has been awarded the APATX 2025 Silver Award for Economic Development Planning by the American Planning Association, Texas Chapter. The honor recognizes Alamo’s strong original vision for guiding the community’s economic growth.

The Project Organic Master Plan was commissioned by the Harlingen Economic Development as a comprehensive framework for future development within a City of Harlingen Tax Increment Reinvestment Zone (TIRZ). This long-term plan introduces a more dynamic and forward-thinking approach to planning and land development than has traditionally been applied in Harlingen.

The master plan emphasizes walkable urbanism, destination-based retail and dining experiences, the transformation of regional detention areas into park spaces, and the inclusion of diverse housing types. It is more than just a visionary document grounded in community input and professional expertise—it serves as a critical roadmap for the continued growth of Harlingen’s Medical District and as a model for future development elsewhere throughout the city.

“Big Ideas” Behind the Urban Design Strategy

The Project Organic Master Plan presents several “big ideas” designed to leverage the site’s unique location within Harlingen and the broader Rio Grande Valley to promote its highest and best use. The plan features a strong design framework for new streets and public spaces, while positioning the area as a vibrant, walkable community centered around destination retail and dining. Most importantly, it identifies, prioritizes, and estimates the cost of essential public infrastructure projects needed to support future development. The plan emphasizes:

A Connected Main Street Spine:

Due to its extensive size, Project Organic incorporates a new connected pedestrian-focused retail “spine” road. This east-to-west connection that bridges from Ed Carey, crosses Camelot, and turns back down to Hale Street to allow for better overall connectivity (both vehicular and pedestrian) across the entirety of the project area. The spine creates the opportunity for a more urban inward-facing commercial main street types of development pattern.

A Destination-Based Retail/Restaurant Experience:

Restaurant and retail spaces that are centered around vibrant and active public spaces see a higher volume of visitors and demand higher rents than those of traditional suburban strip malls set behind expansive parking lots. Within Project Organic, Main Street facing restaurants and retail spaces are focused around a “destination park/plaza” that makes visitors to the development want stay, eat, and shop.

“Eater-tainment” as an Anchor:

Across the country, there has been a recent trend in consumer demand for eater-tainment concepts. These types of activated programs satisfy three main needs that help bring people to sites: food, activities, and social experiences. Project Organic benefits from an eater-tainment anchor node along Camelot that will serve as a destination for Harlingen and provide a great amenity for the medical district that will also help with recruitment of students and professionals. Flanking this anchor with a hotel will help drive foot traffic to the other restaurant/retail areas of the site.

Use Regional Detention as a Park Amenity:

Traditional regional detention basins are commonly built as a “hole in the ground” with little use beyond flood mitigation. The size of the detention basin required for Project Organic opens the potential for its use as a more naturalized park space and public amenity.

A Multitude of Housing Types:

In order to create a diverse and socially vibrant community, the plan incorporate a wide range of housing types, including low- and high-density single-family and options for different scales of multi-family housing. Including various housing options and income levels within the plan is key to bringing a greater number of people to the site’s destinations.

Shaping the Plan with the Community & Stakeholders

The Project Organic TIRZ Plan was developed through a community-based process that began in March 2023. The goal of this process was to ensure that the plan was shaped by the lived experiences, perspectives, and needs of the community through meaningful and insightful engagement. The planning team aimed to amplify the voices of key stakeholders, build trust within the community, enhance the effectiveness of the TIRZ Plan, and identify needs and opportunities the plan could address. Throughout the design process, the team continuously analyzed, integrated, and validated findings alongside public input to inform the final Master Plan.

Working closely with the Harlingen Economic Development Corporation (HEDC), the planning team identified key stakeholders and scheduled a series of open public meetings and workshops. These stakeholders included property owners, members of the local real estate and development community, employees from relevant city departments, elected officials, and others. In total, the planning team facilitated three community workshops during the planning process. These sessions were essential for gathering input, evaluating design alternatives, and shaping a final direction that truly reflected community input.

In addition to public workshops, the planning team conducted one-on-one meetings with key stakeholders to gather feedback on the plan’s progress. These meetings helped build trust in the planning process and provided informal opportunities for property owners directly affected by the TIRZ Plan to express their concerns and share ideas about the plan’s direction.
