Pepin Creek Sub-Area – Creek Relocation & Master Planning Project

The City of Lynden has embarked on a long-range development project known as the Pepin Creek Project.  Its goal is to relocate Pepin Creek and convert approximately 470 acres of agricultural land, within the City’s Urban Growth Area, into developable residential property.  The Pepin Creek Sub-Area (PCSA) has been targeted as the next development area for incoming residents.  The comprehensive planning efforts for this sub-area seek to ultimately create a desirable and attractive neighborhood for Lynden residents to live and recreate.

There are several significant issues currently preventing the “easy” residential development of the PCSA.  At this time, stormwater is collected and conveyed via large ditches adjacent to farm fields and along narrow roads – Double Ditch Road and Benson Road.  The “ditches” along Double Ditch Road are the historical remnant of Pepin Creek which was rerouted for agriculture as the Lynden area was settled.  These ditches are fish-bearing and salmonids continue to use them for spawning grounds, rearing and to get to better habitat north of the Canadian border.  These two major roadways, Double Ditch Road and Benson Road are substandard urban roads and needed improvements are not possible until the existing waterway system is modified.  Furthermore, during seasons of heavy rainfall these waterways and the surrounding areas (which are currently mostly agricultural fields) are often inundated.  Three noteworthy, unique weather events have occurred in this area in the past 20+ years that have resulted in road closures and property damage.

There are multiple complex components of this Master Planning process.

  • Land Use Planning – determining the character of the neighborhood, what will the PCSA look like?
  • Financial Planning – financial assessment tools, identifying major infrastructure costs and funding mechanisms
  • Environmental Planning – creating healthy salmon habitat in the new creek corridor, trail connections, park development
  • Technical Design / Engineering – determining channel capacity, downstream stability, civil infrastructure

Through the Tabs below, the City will seek to update progress as significant milestones are reached.

Combining the water from Double Ditch (Pepin Creek) and Benson Ditches into a single channel and developing what is now mostly vacant agricultural fields will have an impact on the downstream section (south of Main Street) of Pepin Creek.  The new creek corridor is being designed to accommodate that water and new development will need to incorporate state-of-the-art stormwater detention/infiltration facilities within their development.  Additionally, the City is undertaking a significant engineering project to stabilize downstream banks prior to new development occurring.

Downstream Analysis – Field Collection Report

The most complex component of this project is relocating Pepin Creek and Benson Ditch stream away from the roads into a new corridor located midway between Double Ditch Road and Benson Road.  This new channel is being designed to:

  • Accommodate most of the existing water currently flowing year-round in roadside ditches,
  • Provide improved fish habitat,
  • Improve downstream water quality,
  • Provide sufficient drainage control to allow development within the sub-area, and
  • Be a natural neighborhood amenity that provides bike/pedestrian connectivity and other recreational opportunities for residents.

The city has already acquired a majority of the land where the new corridor will be constructed and is working with a local engineering firm (Reichardt and Ebe) to design the elevations of the new channel and other infrastructure projects.

The culmination of the the Pepin Creek project planning process will be the Pepin Creek Sub-Area Master Plan.  This document will integrate the key goals and guiding principles for the long-range development of the new neighborhood.  The Master Plan will assess the technical, environmental, and financial planning considerations with public input and design standards to answer the question:  “What will this neighborhood look like?”

The Master Plan will:

  1. Formalize a vision, with development goals of the Pepin Creek Sub-Area that maximizes residential development while optimizing recreational opportunities.
  2. Provide a detailed phasing plan for the project which addresses the long-term corridor construction and a logical annexation schedule.
  3. Envision infrastructure needs, recreational opportunities, and neighborhood design features to lay the groundwork for the creation of a desirable and attractive neighborhood.

Once completed and approved this document will provide specific guidelines for the way that future development occurs within the Sub-Area.

The City has contracted Communita atelier to develop this master plan.
