Summary
A hybrid scheme for 352 homes on an allocated site at the southern edge of Wisbech was allowed after a hearing. The dispute was about culverting an Internal Drainage Board (IDB) watercourse to form the access. The inspector applied DM7 to assume the separate land drainage consent regime would operate effectively, found compelling reasons under F8(3) for enclosing the watercourse, and approved under S4 with substantial weight to homes that would help meet an affordable housing shortfall.
Issues and findings
- Transition. "I have consulted the main parties and taken any comments into account in reaching my decision" (DL ¶3).
- Separate regimes, DM7: PASS. "Notwithstanding the comments of the IDB, as an application for Land Drainage Consent has not been made or determined, there is no certainty that the proposed culvert would fail to accord with the Strategy" (DL ¶13).
- Grampian condition. "Given the options available for the maintenance and management of the culvert, there is at least some prospect of the action being performed" (DL ¶17).
- Culverting, F8(3): PASS. "Any access to the site via Halfpenny Lane would require culverting at least part of the watercourse" (DL ¶22). "These matters form compelling reasons for enclosing the Halfpenny Lane watercourse such that the scheme would not conflict with the Framework in this respect" (DL ¶22).
- Flood risk elsewhere: no harm. "the culverting of this section of open watercourse in order to provide site access would not increase the upstream flood risk" (DL ¶20).
- Affordable housing and viability. 49 affordable homes; "a policy compliant scheme would be unviable" (DL ¶37).
- S4(2): no trigger. "While the list is not exhaustive, none of the circumstances apply in this case" (DL ¶42).
Planning balance
S4(1), with the scheme also found to accord with the development plan (DL ¶46). Against: reduced infrastructure contributions, moderate weight, "Although there would be no associated development plan harm" (DL ¶43). For: 352 homes; the Council has a five-year supply but "a significant shortfall in affordable provision" (DL ¶44), so "I attach substantial weight to the benefit of providing affordable homes as directed by Framework Policy HO7" (DL ¶45).
What made the difference
The allocation. It supplied both the principle and the "compelling reasons" F8(3) requires for enclosing a watercourse, since no other access was practical. The drainage board's opposition was answered by DM7 and by a negatively worded condition with some prospect of being met. Without the allocation, or with a determined refusal of land drainage consent, the F8(3) and condition findings would have been much harder.
Transferable points
- DM7: a consenting body's statement that consent is "unlikely" is not clear evidence that a separate regime will fail, where no application has been made (DL ¶12–13).
- F8(3) "compelling reasons" for enclosing a watercourse can be an allocation combined with the absence of another suitable access (DL ¶22).
- Land allocated in a broad location for growth at a town edge was decided under S4 (DL ¶22, ¶41).
- HO7 substantial weight is available where there is a five-year supply but an evidenced affordable housing shortfall (DL ¶44–45).
- Infrastructure contributions reduced for viability can meet the Regulation 122 tests and still count as moderate harm in the S4 balance (DL ¶38, ¶43).
Policy findings
Policy codes are those of the National Planning Policy Framework (August 2026) unless a development plan is named.
| Policy | Finding | Weight | Note |
|---|---|---|---|
| DM7 | pass | Internal Drainage Board said Land Drainage Consent was unlikely; separate regime assumed to operate effectively, and no application had been made or determined (DL 12-13) | |
| F8(3) | pass | enclosing a watercourse needs "compelling reasons"; found in the allocation and the lack of another suitable access (DL 21-22) | |
| CC3 | pass | larger culvert section than the existing upstream culvert, so no increase in upstream flood risk; greenfield run-off rates (DL 19-20, 26-27) | |
| TR6 | pass | no severe impact on the network or unacceptable impact on highway safety; junction upgrades and widening of Halfpenny Lane to 6.5 m (DL 31-32) | |
| S4(1) | pass | site allocated within the South Wisbech broad location for growth and treated as within the settlement; benefits not substantially outweighed (DL 22, 41, 46) | |
| S4(2) | not-engaged | none of the listed circumstances apply; the list is noted as not exhaustive (DL 42) | |
| HO7 | benefit | substantial | substantial weight tied to affordable housing need, although the Council has a five-year supply (DL 44-45) |
| HO8 | benefit | mapped - 49 affordable homes, about 13% against a 25% policy target, accepted on viability; no conflict with LP5 (DL 37) | |
| DM5 | harm | moderate | mapped - education, library, GP and ambulance contributions below those requested, on viability; extra burden on infrastructure (DL 38, 43) |
Key facts
- Flat agricultural land on the southern edge of Wisbech, within Phase 2 of the South Wisbech Broad Location for Growth (LP8) (DL 7, 22)
- Halfpenny Lane Drain is an arterial watercourse of the Hundred of Wisbech Internal Drainage Board; a substantial length would be culverted for the primary access (DL 8-9)
- Board would not adopt or maintain the culvert; options are a section 278 agreement, highway adoption or a private management company (DL 14-15)
- Council can demonstrate a five-year supply (figure not stated); affordable delivery averages under 80 a year against a need above 220 (DL 44)
- Site in Flood Zone 1; finished floor levels raised 150 mm, and 300 mm for plots 32 to 34 (DL 24-25)
- Signed UU covers affordable housing, highways, education and library, NHS and ambulance contributions and a toucan crossing (DL 36)
- Costs application by the appellant against the Council, the subject of a separate decision (DL 2)
- Hearing on 8 September 2026; parties consulted on the August 2026 Framework (DL 3)
