Alton Village Environmental Assessment

The EA considers the broad definition of the environment including impacts to the social, cultural, 
economic, and natural environments. The Alton Village Class EA Study considered options to enhance 
connectivity and visitor accessibility to the Alton Village area. 
In identifying the road improvements, the study considered technical (storm water and roadway 
operations and geometrics), aesthetic (streetscaping), and structural requirements; as well as socio-economic;
cultural heritage, and natural environment factors.

Schedule C projects involve the construction of new facilities and major expansions to existing facilities. 
These projects must go through the entire EA planning process (Phases 1-4)

concepts

No. The preliminary corridor design is under development, and will include the design concepts 
presented today, after being confirmed following review of the comments submitted at this PIC.

The implementation of the study recommendations are tentatively planned for 2022, subject to Town 
Council approval and utility relocations

Following completion of the Class EA Study, the project will proceed to Phase 5 ~ Detailed Design and 
Construction

Anyone with concerns related to any aspect of the study may express such concerns in writing to the 
Project Manager at the Town of Caledon within the 30-calendar day review period following the Notice 
of Study Completion. If concerns cannot be resolved through discussions with the Town, then a 'Part II 
Order' (a provision in the MCEA to request a higher level of assessment of the project) may be 
requested. A request may be made to the Minister of Environment, Conservation and Parks within the 
30-day calendar review period requesting an Individual Environmental Assessment in accordance with 
the Environmental Assessment Act.

We estimate the cost to implement the preferred design concepts presented today to be approximately 
$14 million. This is a rough estimate based on information available at this time.

It is anticipated that expanding the urban cross-section to the currently rural roadways will result in 
reducing vehicle speeds approaching the village area. Following the implementation of the preferred 
design, the Town will monitor traffic speeds to determine the effectiveness of the recommended traffic 
calming measures

Yes. The provision of additional on-street parking beyond the east side of Main Street between Queen 
Street and Mary Street is not feasible due to the narrow corridor.

Attempts were made to mitigate impacts to adjacent properties during the development of the preferred 
design. Where impacts are unavoidable, lands disturbed during construction would be repaired to their 
existing condition

Any property required to implement the preferred design for the corridor would be purchased from the 
property owner, following negotiation with the Town. Where required, discussions with impacted 
property owners to secure lands required to implement the preferred design will be initiated during the 
detailed design phase of the study.

During construction, efforts will be made to maintain driveway access and to reduce the length of time 
the access will be impacted. Driveways may be closed for short periods of time (to be coordinated with 
property owner prior to construction activity). 

All applicable LID stormwater management techniques were screened to select the most applicable 
techniques based on the constraints of the roadway. Enhanced grass swales, oil-grit separators, and 
catch basin protectors have been incorporated into the design to improve stormwater quantity and 
quality. 

This means that the new storm sewers will be designed with sufficient hydraulic capacity to 
accommodate the peak flows of a storm of such size that the average time between events of equal or 
greater magnitude is 10 years. 

At this time, no development application has been filed for the referenced lands. If an application were 
to be filed, detailed studies, including a separate drainage and stormwater management assessment 
would need to be completed and approved by the Town. These reports would be made available for the 
public to view.

The recommended alignment will maintain the existing ROW of the roadway, and therefore is not 
anticipated to negatively impact the wooded areas adjacent to the roadway. 

Stormwater management and LID techniques have been incorporated into the design to avoid/minimize 
water quality & quantity impacts to adjacent watercourses. The Design alternatives analysis considered 
measures to reduce impacts to the watercourse and drainage features within the study area by 
increasing the capacity of the storm sewer, incorporating LID techniques., reducing permanent footprint 
impacts, identifying appropriate in-water work timing windows, and erosion control strategies.

The recommended alignment will primarily be maintained to within the existing ROW of the roadway, 
and therefore is not anticipated to significantly impact the adjacent natural area. 

Any trees within the corridor that conflict with the above ground infrastructure will require removal. A 
replanting plan will be completed during detailed design of the to mitigate the loss of any trees. 

The reconstruction of the corridor is not anticipated to negatively impact groundwater quality/quantity. 
Prior to construction, a hydrogeological assessment will be completed to confirm ground water 
conditions, wells in the study area, and appropriate mitigation measures for potential impacts. During 
construction, groundwater wells will be monitored to ensure no negative impacts to groundwater quality 
and quantity. 

A Stage 2 Archaeological Assessment will be conducted in any undisturbed areas prior to any 
proposed construction to ensure archaeological resources are protected. 

The preferred alternative is anticipated to result in only minor encroachment towards properties of 
cultural heritage value with no permanent negative impacts to any structures or landscape features of 
significant cultural heritage value. 

The design of the corridor will incorporate non-intrusive design features that tie into the ongoing 
improvements completed by the Region of Peel, improving the public realm of the village core while 
retaining the cultural heritage of the village. A rural cross section will be retained on Main Street North 
of Mary Street.
