Reviewed build intelligence

What the documents establish

Government document review

The appeal concerns an amendment to ABP-303804-19. The May 2026 EIAR distinguishes amended blocks from unchanged permitted blocks. The current Commission description refers to 252 units while the EIAR describes 414 units across the permitted and proposed development together; these different source scopes are not converted into a single current project total.

The amendment changes specified blocks, not every permitted building

Proposed in application · Amended blocks in the May 2026 submission, against permission ABP-303804-19

What the evidence says
The EIAR scope table says the amendment relates to C1, C2, C3, D1, E1, E2 and G; former E3, E4 and E5 are removed. A1, B1, B2, B3, B4 and H remain as permitted without proposed changes in this application.

Why it may matter — interpretation
Interpretation: prevents engineering quantities and material needs being assigned indiscriminately to every block.

What is not established
The EIAR’s combined 414-unit context and the Commission’s 252-unit description are not treated as interchangeable. No current whole-development or added-unit headline is published.

Removal of Former Blocks E3, E4 and E5

Two separately connected attenuation systems in the EIAR site design

Proposed in application · Whole EIAR-site drainage design, including retained permission context; not solely the new amendment’s quantities

What the evidence says
The hydrology chapter describes 905 m³ in a Stormtech below-ground attenuation structure north of Block D and 905 m³ in a reinforced-concrete tank beside B2 under the road. Each connects independently to the council collection system with a Hydro-brake or similar flow control.

Why it may matter — interpretation
Interpretation: identifies different underground storage constructions and separate hydraulic connections.

What is not established
These are proposed source-specific capacities, not procurement quantities or evidence that both systems are newly required by the amendment. Final detailed design and approved substitutions are not established.

Later review calls for coordinated foundation and construction controls

Reviewer recommendation · 20 July 2026 review of further information, following the earlier March assessment gap

What the evidence says
The July review considers the revised piling and bedrock assessment satisfactory and recommends conditions requiring agreement of piling and foundation details before foundation construction, plus an updated detailed construction environmental management plan before works. It identifies noise, vibration, groundwater, nearby structures and underground services as matters to address.

Why it may matter — interpretation
Interpretation: points to foundation design, monitoring and construction-method coordination still to be resolved through later conditions and submissions.

What is not established
These are the reviewer’s recommended conditions. This document does not prove that the decision adopted them, that a condition was discharged, or that foundations have started.

Remaining document questions
  • Which later official decision, approved detail or revision changes these source-specific findings?
  • Has a phase-specific official record established the selected equipment or installed specification?

Selected pages of 3 government-published PDFs were visually inspected. Three later PDFs inspected on the listed pages. Earlier chapter and March review were downloaded/text searched for revision context but are not counted as visually inspected technical evidence. Proposals do not establish procurement or installed work.
