Site-specific study added to Conception Bay South subdivision approval-in-principle

A Newfoundland and Labrador planning adjudicator required a site-specific Land Use Impact Assessment for a proposed Conception Bay South residential subdivision, varying the town’s approval-in-principle without otherwise disturbing it. Adjudicator Christopher Forbes issued the June 12, 2026 decision in Andrea and Jason Lundrigan v. Town of Conception Bay South, Appeal No. 15-006-094-031.

The Dec. 17, 2025 approval was varied to require the applicant to complete the assessment under section 5.10(1)(b) of the town’s Development Regulations. All other terms remained in effect. Forbes also ordered the town to repay an amount equal to the appellants’ appeal fee, without specifying a dollar amount.

The case concerned an approval-in-principle, not a final development approval. The town emphasized that its conditions had to be satisfied before development approval could issue. At the May 12 hearing, the Lundrigans advanced seven grounds, focusing particularly on the high-water mark and the absence of a land use impact assessment.

Flooding evidence challenged the old classification

The appellants relied on photographs of flooding in the area around Cross Brook and their own observations, including recent flooding affecting proposed development properties. Andrea Lundrigan, a geoscientist and longtime area resident, challenged the adequacy of the 2011 geological-hazard report on which the town relied. Forbes found the appellants very credible.

The appellants argued that vegetation removal, grading, impervious surfaces and changes to surrounding land undermined reliance on the old low-risk classification. The report’s description of low vulnerability was qualified where human activity changed the landscape and increased hazards. It also expressly excluded hydrographical and climatological analysis of a stream or watershed and cautioned that it was not a substitute for formal flood-risk mapping.

A commissioner’s May 2023 report concerning a municipal-plan amendment also recorded flooding concerns and recommended a site-specific study at the development-application stage. Both sides recognized that the report arose from a different process. Forbes nevertheless considered its discussion of residents’ concerns and the benefit of a site-specific study relevant evidence, rather than treating its recommendations as automatically binding on this approval.

Discretion had to rest on sound facts

Forbes emphasized the limits on his authority under the Urban and Rural Planning Act, 2000. Relying on Mount Pearl v. Mount Pearl Local Board of Appeal, he explained that an appeal was not an opportunity to replace municipal discretion merely because the adjudicator disagreed. But the principle drawn from Stroud v. Newfoundland and Labrador (Central Regional Appeal Board) allowed intervention where discretion rested on a mistaken understanding of material circumstances.

He accepted that the approval-in-principle was a discretionary decision under section 4.10 of the Development Regulations, which allowed it where the application conformed to the municipal plan and regulations. The critical question was whether the town could properly rely on the low-risk classification when deciding whether to require the assessment.

Section 5.10(1)(b) required a site-specific Land Use Impact Assessment for proposed residential development in an area identified as Moderate Hazard. Prepared by suitably qualified people, the study was to evaluate susceptibility to storm surges, erosion or flooding and consider elevation, topography and geomorphology. The town acknowledged relying on the 2011 report’s low-risk classification; Forbes inferred that a moderate-risk classification would have led it to require the study.

The town maintained that the developer’s subsequent diligence would address flooding and runoff concerns, and said a hydrological assessment was already required. Condition 16 required assessment of infrastructure and downstream waterways to determine whether development drainage could be accommodated and, if not, achievement of no net increase in runoff as required by the town. The town retained the final determination of the drainage solution after reviewing assessments or proposals.

Forbes acknowledged those protections and the town’s continuing discretion. He nevertheless found it speculative to assume that ordinary post-approval diligence would necessarily address everything a full Land Use Impact Assessment would examine.

The extensive flooding evidence, credible testimony, commissioner’s observations and the hazard report’s age and limitations made reliance on its classification unreasonable for this purpose. Forbes found that extensive flooding occurred regularly or semi-regularly. The town’s low-risk classification reflected a mistaken view of material circumstances, justifying the additional assessment requirement. The remedy was a site-specific study, not an independent technical assignment of a new hazard category.

Six other challenges failed

Forbes rejected the remaining grounds for the following reasons:

• High-water mark: The approval adequately addressed the requirement for appropriate governmental authorization where development would occur within 15 metres of the mark. The applicable rule was not an absolute prohibition on development within that distance, and determining the mark was not necessarily required before issuing this approval-in-principle.
• Flood-risk mapping: The Development Regulations did not explicitly require the town to undertake it. The commissioner’s suggestion that mapping would be beneficial did not create a legal requirement to include it in the approval.
• Environmental and fish-habitat assessments: Condition 6 was sufficiently broad to address these issues consistently with the Development Regulations.
• Open space: Section 7.8(5) allowed the town to require conveyance of a riparian area in satisfaction of the open-space requirement.
• Building-line setback: The challenge to a nine-metre rather than 10-metre setback failed because section 7.7 permitted the town to establish building lines at its discretion without prescribing criteria for doing so.
• Procedural fairness and resident evidence: Forbes found no procedural unfairness sufficient to support the appeal, apart from the hazard-classification issue already addressed.

The decision’s notice states that an appeal to the Supreme Court of Newfoundland and Labrador is available on a question of law or jurisdiction. It must be filed no later than 10 days after the appellant receives the adjudicator’s decision, not 10 days after the decision date.
