Key Findings

  • 01Increased obstruction of retail signage by street trees is significantly associated with a decrease in commercial property rents.
  • 02The study controlled for socio-economic variables, isolating the effect of tree obstruction on rent.

Application

Design takeaway

When designing or planning urban commercial spaces, carefully consider the placement and density of street trees to ensure optimal visibility for retail signage and to avoid potential negative impacts on commercial property values.

How to apply

When proposing streetscape designs for commercial areas, conduct a visual impact assessment of proposed tree planting on existing or potential retail signage. Consider alternative tree species or planting arrangements that minimize obstruction.

Project actions

  • 01When researching a commercial area, consider how the natural environment (like trees) might affect the businesses there.
  • 02Think about how visual elements, not just physical ones, can influence economic outcomes.

Method & Evidence

AimTo investigate the relationship between the degree to which street trees obstruct retail signage and the monthly rent of commercial properties in developed districts of Seoul.
MethodQuantitative analysis using scene parsing and regression modeling.
ProcedureGoogle Street View imagery of commercial districts in Seoul was analyzed using deep learning-based semantic segmentation to identify and quantify elements like street trees, sidewalks, and buildings. The proportion of street trees obscuring retail signage was calculated. This data was then used in an Ordinary Least Squares (OLS) regression analysis to determine the impact on monthly rent, while controlling for socio-economic variables.
ContextUrban commercial districts in Seoul, South Korea.

Variables

IVDegree of street tree obstruction of retail signage.
DVMonthly commercial rent.
CVSocio-economic variables of the commercial districts.

Strengths & Limitations

Strengths

  • +Utilizes advanced deep learning for objective scene parsing.
  • +Employs quantitative regression analysis to establish a correlation.

Limitations

This study is specific to Seoul; results might differ in cities with different urban layouts, tree species, or retail market dynamics. The exact 'value' of a sign's visibility is complex and not fully captured.

Reliability & validity

The use of deep learning for scene parsing likely enhances reliability. Validity is supported by controlling for socio-economic factors, but the direct causal link and the precise economic valuation of visibility require further investigation.

Think critically

To what extent can the negative economic impact of street trees on retail rent be mitigated through design interventions, such as selective pruning, alternative tree species, or innovative signage solutions?

05

Design Principles

"Balance ecological benefits with commercial functionality in urban design to ensure sustainable and economically viable urban environments."

This research highlights a critical consideration for urban planners and designers involved in commercial district development. It demonstrates that while green initiatives are valuable, their implementation must account for potential economic consequences for local businesses and property owners.

06

What This Means for Your Design

Putting too many trees on the street can block signs for shops, which might make the shops less visible and lower the rent for those spaces.

How to use in your project

  • 1.Use this research to justify design decisions related to urban landscaping in commercial zones, explaining how your design aims to optimize visibility and potentially support commercial rent values.
