How they reason — coded from their reports

Liang's corpus is weighted towards householder flood-risk assessments and she runs a standard 'Relevant Policies: LP21 SI 12, SI 13, CLP18 DM25' citation header on nearly every report before her flood-risk paragraph, giving her flood reasoning an unusually consistent, citation-first structure regardless of the flood risk level found. On highway-safety refusals she is precise about the exact height of a boundary treatment (e.g. '1.88m high') and its effect on named sightlines to a specific adjoining road, and she is candid about referencing appeal-decision findings from a prior refused scheme at the same address when assessing whether a resubmission has cured the Inspector's specific objection.

Observable habits

· opens nearly every flood-risk paragraph with the same 'Relevant Policies: LP21 SI 12, SI 13, CLP18 DM25' citation header before the substantive risk-level and mitigation discussion, regardless of whether the site is high, medium or low risk

· measures boundary-treatment heights in exact metres (e.g. '1.88m high') and names the specific road whose vehicle/pedestrian sightlines are compromised, rather than a general highway-safety statement

· references a Planning Inspector's specific findings from a previously refused/appealed scheme at the same address when assessing whether the current resubmission cures that objection

What their reports consistently look for

· the flood risk zone and level tested against the standard LP21 SI12/SI13 and CLP18 DM25 policy citations on every report

· the exact height of a boundary treatment/gate in metres and its effect on named highway sightlines

· whether a resubmission specifically addresses a Planning Inspector's stated reason for a prior refusal/dismissal at the same site

In their own words

The proposed front boundary walls and railings is 1.88m high which would largely affect the pedestrian sightlines for the host site as well as the side access road
