Project Overview

The city of Aspen is updating its Urban Runoff Management Plan (URMP) — a key manual that provides standards and guidance for managing stormwater runoff in development and redevelopment projects across the city.

The most recent update was adopted in 2014, with the URMP guiding best practices for over a decade. This update aims to:

  • Align the manual with current industry standards
  • Refine and modernize methodologies for stormwater management
  • Improve clarity, usability, and accessibility for all users


Join the Conversation

We invite members of the development and engineering community, consultants, and interested stakeholders to participate in an upcoming meeting to help shape the updated URMP.

Date: Wednesday, October 15

Time: 3:00 – 5:30 p.m.

Location: Pearl Pass conference room of Aspen City Hall,

427 Rio Grande Place, Aspen, CO 81611


About the Meeting

The session will be led by Wright Water Engineers, who will guide participants through the existing manual and individual chapters. This will be an interactive opportunity to:

  • Identify challenges and gaps in the current URMP
  • Share comments and ideas for improvement
  • Discuss industry trends and opportunities to enhance the manual

The goal of this initial meeting is to gather feedback and input from the development community to inform the next version of the URMP — ensuring it reflects today’s best practices and meets Aspen’s evolving needs.


Your voice is essential in shaping a manual that supports sustainable, effective stormwater management in Aspen.
