Mill Pond Park Renewal Projects

A Stormwater Environmental Assessment has been completed to evaluate existing stormwater drainage within the Mill Pond Park study area and to propose options for rehabilitation of Mill Pond, the Heritage Estates stormwater facility and valleyland erosion sites north and south of Mill Pond. This study will evaluate a number of options and determine the best rehabilitation solution to improve water quality, reduce erosion and prevent flooding in the area.

Mill Pond 

Although not designed as a formal stormwater management facility, Mill Pond provides a stormwater management function to the City with more than 600 ha of lands draining into it. Over the years, this has resulted in the accumulation of a large amount of sediment that now needs to be removed. Additionally, the outlet of Mill Pond is a barrier to fish, preventing their access to upstream waters while allowing water to warm up before entering the downstream reaches, which has an overall negative impact on fish.

Heritage Estates stormwater facility north of Mill Pond

The Heritage Estates stormwater facility north of Mill Pond has operated since 1987, servicing a residential area to the north and east of about 52 hectares. This storm pond has a large amount of sediment in it that needs to be removed and parts that are in need of rehabilitation.

Valleyland erosion sites along the Upper East Don River

There are a number of sites north and south of Mill Pond that are in need of restoration with issues such as a failing bank support structures and culverts that are in poor condition and in need of repair or replacement.

This study was conducted as a Schedule B in accordance with the Municipal Class Environmental Assessment process. 

Project File Report

A Project File Report has been prepared, which outlines the project background, details the evaluation of the rehabilitation options, and includes the conceptual designs for the preferred solutions. The Project File Report is posted under the 'Notice of Completion' tab at the bottom of this webpage and will be open to public consultation until February 2, 2024.

Richmond Hill residents have enjoyed Mill Pond for many decades and it's time to update and revitalize this natural oasis in the heart of the City. Together with the EA (described in the above drop down), the Park Revitalization Master Plan project will guide the phased revitalization of the park and stormwater management works. Existing and potential new outdoor and recreation facilities, trails and natural heritage enhancement projects will be discussed with the community and prioritized for implementation over time to reduce disruption to park users as much as possible. A Parking Strategy will also be completed. The revitalization of Mill Pond Park will aim to:  

• Improve connectivity and wayfinding, and link the southern portion of the park with the new City lands on Regent Street in the northern portion of the park; 
• Use creative placemaking techniques to pull together all elements and sections of the park into a unified whole;
• Balance the visual, ecological, recreational, cultural and maintenance/operation needs of the park and stormwater facility;   
• Capitalize on the park's assets to create a public space that promotes citizen's health, happiness and well-being; and
• Enhance the natural character of the park that will foster pride and promote a sense of belonging for Richmond Hill citizens.

The Mill Pond Park Revitalization Master Plan was approved by Council on April 10, 2024.  The redesign and construction of the new park is expected to take place over the next seven years, dependent on capital funding. Please check back for further details or subscribe to this page for updates by clicking 'Receive email updates' below.

Open House #2

Stormwater Rehabilitation/Environmental Assessment Comment Period

An Open House was held on Wednesday, June 29 at the Richmond Hill Centre for the Performing Arts where residents were invited to join us for an overview of the Mill Pond stormwater rehabilitation project,  as well as review and provide feedback on the proposed rehabilitation solutions. To facilitate public input for those who were unable to attend the in-person event, an online survey was open between June 29 and July 17th.
