How Does Blue Infrastructure Affect the Attractiveness Rating of Residential Areas? Case Study of Olsztyn City, Poland

Abstract

Blue Infrastructure (BI) is a system of water-based ecological and engineering interactions that provides multiple social and ecosystem benefits in an urbanized environment. The study answers the questions: (1) Can the assessment of the attractiveness of residential areas be influenced by the availability of water reservoirs with a specific functionality? (2) What are the indicators that determine this impact? The research aimed to develop a methodology for the evaluation of residential neighborhood spaces, considering the indicator of the functional value of water bodies and their accessibility. The following research hypothesis, that the recreational and esthetic functions of water bodies along with the accompanying infrastructure are the most attractive features that hold the greatest significance in evaluating residential areas close to them, was verified. Cartographic and field inventory studies were conducted to prove this. An inventory form was applied along with social research using a geo-survey to determine the ranking of individual water bodies. As part of the test of the developed method, all water bodies in the city of Olsztyn (northern Poland) were evaluated. The test revealed that the indicators related to the functional value of water bodies and their accessibility influence the assessment of the residential neighborhoods’ attractiveness. Therefore, they should be considered in the assessment of cities containing both natural and anthropogenic water bodies.
