Final Survey Report 

HHM & Associates, Inc. has completed their report detailing the results of the City of Plano's Heritage Resource Survey 2023. The report contains information about which neighborhoods in Plano were determined to be eligible for listing as Potential Heritage Resources (PHRs) or potential Neighborhood Conservation Districts (NCDs).

Information about the survey project, including a project description, a project map, and further definitions for PHRs and NCDs, can be found below.

What Is a Heritage Resource Survey?

A Heritage Resource Survey consists of the comprehensive identification, research, and documentation of buildings, sites, and structures of any historic, cultural, archaeological, or architectural importance.  With rare exceptions, locations examined during Heritage Resource Surveys are observed from public right-of-way (ROW), primarily the adjacent street, without the need for survey personnel to enter anyone's private property.  The City of Plano periodically commissions these surveys to evaluate sites or districts that are of known historical significance, such as Downtown, Haggard Park, and several Heritage Landmarks throughout the City.   Additionally, these surveys help City staff evaluate the significance of properties and neighborhoods that have recently, or will soon, cross the 50-year age threshold, after which they may be considered "historic."    

These surveys are also crucial to updating Plano's Heritage Preservation Plan, which serves as the guiding document for the city’s Heritage Preservation Program.  The current Preservation Plan includes surveys of neighborhoods built up to 1969.  For the 2023 update, the City is looking to survey neighborhoods and properties with structures built between 1970 and 1975.  This evaluation is necessary to ensure that unique architecture and development patterns that characterize these locations are not overlooked as potential candidates for future heritage-related designations.  

The project consultants, HHM & Associates, Inc. (HHM) will be surveying neighborhoods and properties that feature houses and buildings constructed between 1970 and 1975.  Additionally, they will be surveying a number of older neighborhoods and properties that were recommended for more research during the las Preservation Plan update.  If you received a notification letter from the City, it is because your property/neighborhood has been identified as meeting one of these criteria and will be included in the survey.

What Is the Scope of the Survey?

Windshield Level Survey sample Page 1

Windshield Level Survey

For neighborhoods/properties built between 1970 and 1975, HHM will conduct a Windshield Level Survey (WLS).  A WLS typically focuses on the neighborhood or district as a whole, rather than on individual buildings, noting streetscapes, the general character of its housing stock or commercial buildings, representative buildings and structures, and the layout of its spaces in general.  Photography includes streetscape photographs rather than photographs of individual buildings. No historical research or analysis is included. The most common goal of the WLS is to recommend whether or not the area should be surveyed in greater detail in the future.  The WLS will be conducted entirely from public ROW and no access to private property will be necessary.  Click the image to the left to see a WLS sample form.

During the 2018 survey, a number of neighborhoods and properties were identified as needing more research to determine their significance and potential for designation or inclusion as Potential Heritage Resources.  Click Here to see maps of these locations, as shown in Chapter 5 of the current Preservation Plan.  For these properties, HHM will conduct a Reconnaissance Level Survey (RLS).  An RLS typically documents individual structures, including two photographs of each building, a map of the building location, and a form noting the building’s address, date of construction, use type, architectural style, physical integrity, and eligibility for local historic designation or National Register listing. Broad contextual research is conducted to guide eligibility determinations.  While all of the properties within neighborhoods will be surveyed from public ROW, entry to the larger agricultural properties will need to be coordinated with the owners.  Click the image to the left to see an RLS sample form.

What is a Potential Heritage Resource?

A Potential Heritage Resource (PHR) means a structure, collection of structures, site, or landmark of historical, cultural, archaeological, or architectural importance listed in the Heritage Preservation Plan.  A PHR has not received heritage resource designation, but has the potential to become designated with further historic research, restoration, or property owner interest.  Please note, listing is informational only and does not subject the structure or site to any architectural review by the Heritage Commission or include any changes to existing zoning.

The Preservation Plan contains a list of properties and districts determined to be PHRs, which will be updated with the results of the 2023 survey.

What is a Potential Neighborhood Conservation District?

A Neighborhood Conservation District (NCD) protects the distinct architectural, physical, or visual character of Plano’s older neighborhoods. It reduces the impact of customized building, lot and zoning standards (setbacks, materials, roof slope, etc.). 

Only owners and residents in the individual neighborhood can request the creation of an NCD. This tool focuses on the neighborhood’s general form, scale, rhythm, design, style, and characteristics deemed important to those who request it. The detailed NCD regulations are outlined in Article 11.1000 of the City of Plano Zoning Ordinance. 

Neighborhood Conservation Districts and Heritage Districts differ in purpose (what to protect) and administration (how to protect). Unlike Heritage Districts, NCD regulations are only as restrictive as desired by the neighborhood and do not require any review by the Heritage Commission or other architectural review boards.

Second Public Meeting Recap 

Thank you to everyone who attended our second public meeting for the Heritage Resource Survey project on November 14, 2023.  Emily Payne from HHM & Associates, Inc. detailed the results of the survey, identifying which neighborhoods and properties were identified as being eligible for listing as Potential Heritage Resources or Potential Neighborhood Conservation Districts.  Additionally, City staff also discussed coming updates to the City's Heritage Preservation Plan.

First Public Meeting Recap 

The first public meeting for this project was held on Tuesday, June 6, 2023.  Please see the video below for a recording of the meeting, as seen by those participating via Zoom.  Representatives from the City of Plano and HHM, Inc. answered several questions about the project and its outcomes.  If you have questions, there's a good chance we covered them in the meeting!
