Underground Stormwater Systems are buried detention and infiltration systems that store and manage runoff beneath a site. In Richmond Hill, Harrowgate Group takes on underground stormwater systems end to end: the site is surveyed and scoped, the work is built and managed on site, and the project is completed to the engineered plan.
Most Richmond Hill underground stormwater systems jobs involve sites with limited surface space. Managing stormwater underground where surface space is tight are the recurring drivers; each Richmond Hill project is sized to its own situation, not a one-size approach.
Richmond Hill's need for underground stormwater systems (York Region) is driven largely by commercial and office, institutional and healthcare, retail, and mixed-use intensification. Richmond Hill's Beaver Creek business park and Yonge corridor drive commercial, office, and institutional construction alongside mixed-use intensification. Demand centres on business-park site work, servicing, and structured parking.
Most of it sits around Yonge Street corridor, Headford and Beaver Creek business park, and the 404 employment lands. Much of the Richmond Hill work is for developers, institutional owners, and the City of Richmond Hill, each needing the job built to the drawings, to code, and documented.
Across Richmond Hill, underground stormwater systems covers a real range of property, commercial and office, institutional and healthcare, retail, and mixed-use intensification. Each calls for a different response, so Harrowgate Group scopes every Richmond Hill project to the building and its use rather than one playbook.
