Stormwater calculation application for low impact development in the conceptual design phase of urban site development

Abstract

There are many existing Low Impact Development (LID) applications available to calculate stormwater runoff volume, but they often fail to address LID systems in the initial design stages. To address this problem a LID application was developed for international use that supports designers considering how to reduce stormwater runoff through LID strategies. The result is an iterative design process that allows designers to visualize results. This helps users make informed decisions when it comes to stormwater management practices that are based on a combination of readily available local climate data and existing site conditions to create preliminary runoff results.

Urban Participation + Research + Regulation Method (PRRM) to Broadly Implement Green Urban Infrastructure Solutions

“…By implementing green roofs, green walls and green streets solutions stormwater, runoff can be reduced by 13% [17] According to Vancouver's Rain city strategy [18], a global green urban infrastructure strategy can retain 90% of a city's runoff. more specific data on the reduction of runoff is achieved by applying the low impact development (lid) Application [19] in each particular project.…”

“…3.3.1 contribution to the reduction of runoff from the site in order to achieve the runoff reduction in both projects, the lid Application [19] is applied. this is a user-friendly application to calculate during the design process, the influence of lid solutions to reduce the runoff.…”
