can accommodate residential development on the subject lands.
by development on the subject lands; however, the sewer will have to be upgraded for the
Lunor residential development. Therefore, the unopened road allowance through the
subject lands will ultimately be disturbed, regardless whether the development occurs
on the subject lands.
Storm Water Management (volume and quality)
Citizens expressed concerns that storm water currently flows directly into Larch Creek from the storm
pipe at the end of Dunke Avenue, and that the addition of residential units and removal of trees and
vegetation would negatively affect the water quality in the creek and increase the risk of flooding.
result in an increased amount of runoff into the water system (with greater amounts of
sediment and increased temperatures), there are ways to manage these issues.
developments as a method of managing the volume of storm water. Now, storm water
management ponds are utilized to manage both volume and quality of water. Installing a storm
water management pond in the general vicinity of the subject lands is not likely necessary as
the scale of the proposed development would not warrant this approach. For this scale of
residential development, an oil-grit separator could be incorporated into the new road to
manage water quality. In addition, forms of quality control can also be installed at the end of
the storm pipe on Dunke Avenue. Staff suggests that conservation easements for the
backyards of residential lots are also considered as a method of managing storm water quality
and quantity.
Through the development process, a number of studies will be completed to inform the
detailed design of the residential development. For example, a Groundwater Monitoring
Program will be undertaken to evaluate the ground water and how it relates to development of
the subject lands. In addition, a Storm Water Management Plan is required, which will be
reviewed by Township Engineering and GRCA Staff. The information developed through all
studies will result in specifications that will be incorporated into a detailed design, allowing Staff
to evaluation options. This process will ensure that issues including water flow, water quality,
drainage, erosion, flooding, and access are addressed.
The Region of Waterloo currently own Parcels 4 and 5. The Township is exploring the purchase of
these parcels.
If the Township does not secure the Regional lands but the Township-owned land is developed
and the road is built, provisions can be made to secure future residential development on the
