How & Why This Portal Was Created
An open, transparent explanation in plain English of the geomatics engineering behind our maps, the basis of ESG in UK planning law, and why the Parish Council is mobilising community evidence in the absence of an adopted Neighbourhood Plan.
How This Portal & Interactive Map Were Constructed
When property developers consult on major rural housing schemes, they typically distribute glossy brochures with simplified, unscaled artistic impressions. To enable our community to evaluate the proposal objectively, Codford Parish Council commissioned an open-source, survey-grade digital evidence portal. Here is how it was built:
Rather than guessing boundary lines, our engineers implemented a rigorous 3-tier legal hierarchy: Tier 1: HM Land Registry (HMLR) Registered Cadastral Titles → Tier 2: Ordnance Survey / OpenStreetMap Highway & PRoW Assets → Tier 3: Physical Hedgerows & Historic Downland Tracks. The redline boundary conforms strictly to the registered agricultural title north of Beanis Path across 15 exact vertices and strictly excludes the ANZAC War Graves Cemetery.
Geodetic transformations between British National Grid (OSGB36 / EPSG:27700), WGS84 (EPSG:4326), and Web Mercator (EPSG:3857) are executed using a full 7-parameter Helmert ellipsoid transformation (Airy 1830 to WGS84), ensuring millimetre-accurate vector snapping without the 85m Easting skew inherent in naive linear approximations.
The portal integrates two distinct developer raster drawings: Drawing 1 (CAD Masterplan) and Drawing 2 (OS Context Plan), both georeferenced and calibrated to the localised site envelope (3.7 - 4.6 ha) using shared survey control points aligned with Ordnance Survey and HM Land Registry boundaries.
To accurately integrate non-planar architectural graphics, we mapped the precise geographic section cut line for Drawing 3 (Beanis Path Street Elevation) along the northern residential building facade directly fronting Beanis Path. Clicking the section marker on the live map reveals the high-resolution architectural drawing with contextual 2-storey ridge height analysis (~7.8m - 8.5m).
To assess micro-topography, skyline prominence, and surface water drainage risks, we ingested 2.1 million bare-earth elevation data points from the official DEFRA / Environment Agency 1m LiDAR Composite DTM. Topographic profile modelling reveals an 18.58 metre (61.0 foot) vertical fall across the 243.5m parcel (average gradient of 7.6% / 1 in 13) sloping directly south towards Beanis Path. This steep drop confirms that upper-terrace dwellings (98 - 101m AOD) will significantly overlook existing village bungalows (82 - 84m AOD) and creates substantial overland runoff risks requiring rigorous SuDS attenuation.
Challenges of Locating an Unreferenced Sketch Plan: The indicative masterplan circulated in developer literature is an unscaled, non-georeferenced promotional graphic lacking British National Grid (OSGB36) coordinates, geodetic survey control points, or engineering datum anchors. Translating an unreferenced artistic leaflet into authoritative GIS layers (OpenStreetMap / Ordnance Survey / HM Land Registry) involves resolving inherent perspective skews, raster distortions, and line-weight ambiguities.
Parish Council Formal Geomatics Request: Codford Parish Council has formally requested authoritative digital CAD files (DWG/DXF), GIS shapefiles, and raw topographic survey data from C G Fry & Son and Chapman Lily Planning. Upon receipt of these engineering datasets, the Parish Council will immediately update and refine the interactive spatial layers on this portal to provide the highest achievable survey-calibrated precision.
The Basis of ESG in UK Planning Law & Sustainable Development
In modern corporate governance, ESG stands for Environmental, Social, and Governance. In the context of British town and country planning, ESG is not a mere public relations slogan - it is directly grounded in the statutory test of Sustainable Development set out in Paragraph 8 of the National Planning Policy Framework (NPPF) and the Wiltshire Core Strategy.
E Environmental: Ecological Stewardship & Chalk Hydrology
The environmental objective of the NPPF requires development to protect and enhance our natural, built, and historic environment:
- River Wylye SAC Nutrient Neutrality: Under the Conservation of Habitats and Species Regulations 2017 and Core Policy 69, any new dwelling in the River Avon catchment must achieve certified phosphorus neutrality to prevent toxic algal blooms in internationally protected chalk stream habitats.
- Mandatory 10% Biodiversity Net Gain (BNG): Mandated by the Environment Act 2021, requiring measurable on-site habitat creation calculated using the statutory Defra metric.
- Cranborne Chase Dark Sky Reserve: Codford sits within the Cranborne Chase International Dark Sky Reserve (IDSR). NPPF Paragraph 191 mandates strict lighting controls (0% Upward Light Ratio, max 2700K warm luminaires) to protect dark rural nightscapes.
- Upper Chalk Hydrogeology & SuDS: Surface water attenuation basins must account for seasonal high groundwater tables in Salisbury Plain chalk geology, preventing catastrophic basement and sewage surcharging.
S Social: Genuine Local Needs & Community Viability
The social objective requires supporting strong, vibrant, and healthy communities by ensuring housing meets local needs and infrastructure keeps pace:
- Strict 30% Affordable Housing (Core Policy 43): Delivering 18 genuinely affordable homes out of 60, protected against developer viability clawbacks, with a mandatory Codford Local Connection Cascade giving first priority to local families and workers.
- Primary Healthcare & Education Capacity: Legally binding Section 106 capital contributions to expand the Codford GP Surgery and primary school classroom facilities to absorb ~150 new residents.
- Highway Safety & Active Travel (NPPF Section 9): Securing an adopted Section 278 continuous pavement along Chitterne Road so children and elderly residents can walk safely to the High Street without walking in the live vehicular carriageway.
- Heritage & Memorial Solemnity (NPPF Section 16): Preserving the rural setting and peace of the Grade II* St Mary's Church and the Commonwealth War Graves Commission ANZAC Memorial Cemetery.
G Governance: Transparency & Binding Section 106 Accountability
The governance dimension enforces procedural fairness, developer transparency, and legally binding commitments:
- Pre-Application Scrutiny (NPPF Paragraphs 39 - 46): Early engagement must not be a tick-box public relations exercise; it must address genuine local constraints prior to submission.
- Binding Section 106 Obligations (TCPA 1990 s.106): Legal agreements must be directly related to the development, necessary to make it acceptable in planning terms, and fairly related in scale and kind (CIL Reg 122).
- Equal Access to Evidence (Aarhus Convention): All affected residents are entitled to view uncompressed geospatial data, objective planning constraints, and financial viability appraisals without paywalls or restrictive barriers.
Statutory Planning Regulations from 31 October 2026 & Schedule 2 Impact
How The Town and Country Planning (Discharge of Local Planning Authority Functions) (England) Regulations 2026 transform decision-making from discretionary committee politics to empirical evidence.
1. Officer Delegation Default
Abolishes automatic Councillor call-ins. Major Schedule 2 schemes (10 - 100 homes) are determined by delegated planning officers unless referred via statutory criteria.
2. Statutory Gateway Test
Public Planning Committee referral requires satisfying an objective Gateway Test: demonstrating substantial policy departure, acute highway deficits, or sensitive environmental harm.
3. Dual Schedule 2 Safeguards
Operates as Schedule 2 Major Application (governance) and Schedule 2 EIA Development (River Wylye SAC hydrological connectivity), mandating binding Habitats Regulations nutrient neutrality.
4. Front-Loaded S106 Terms
Negotiations must occur before officer report drafting: locking in the £400,000 Village Hall Renewal, £260,000 Footway, and 30% on-site affordable housing (18 homes) under Core Policy 43.
Planning Policy Matrix: Context, Requirements & Potential Conflicts
This matrix evaluates the proposed development of up to 60 dwellings off Chitterne Road against current English planning law, the National Planning Policy Framework (NPPF), the Wiltshire Core Strategy, emerging Local Plan policies to 2038, and statutory environmental legislation. It identifies where the proposal creates key policy tensions and specifies the mandatory legal resolution mechanisms required.

Evaluating Sustainable Development & Potential Wider Community Benefits
1. The Sustainable Development Balance (NPPF Paragraph 8)
Under national planning policy, achieving sustainable development requires balancing three mutually reinforcing objectives: economic, social, and environmental. The planning policy matrix above demonstrates that while the proposal brings economic activity during construction, it introduces substantial tensions with environmental and spatial development plan policies - most notably settlement hierarchy restrictions (Core Policy 2), River Wylye SAC phosphate limits (Core Policy 69), and pedestrian safety deficits along Chitterne Road.
However, the Parish Council’s role is not simply to register a blanket refusal. By applying the ESG framework rigorously, the Parish Council can hold the developer to the highest standards of planning law, determining whether the proposal can be reshaped to deliver genuine, lasting community benefit.
2. Potential Wider Community Benefits (The 'Win-Win' Scenario)
If the applicant complies strictly with the statutory mitigation mechanisms outlined in the policy matrix, the scheme could deliver transformative infrastructure upgrades that Codford has sought for decades:
24 genuinely affordable homes secured under a legally binding Codford Local Cascade would allow young village families and local key workers to remain in Codford rather than being priced out.
A developer-funded Section 278 adopted continuous pavement would resolve a dangerous historic highway hazard, allowing pedestrians to walk safely from the north of the village to the High Street.
Transferring the ~2-hectare Community Orchard and SuDS meadow into public Parish Council freehold ownership with a 20-year endowment secures permanent recreational open space for generations.
Ring-fenced Section 106 capital contributions would fund clinical expansion at the Codford GP Surgery and additional classroom capacity at Codford Primary School.
3. The Pre-Application Strategy: "Comply or Refuse"
The Parish Council's strategy ahead of the statutory determination period is clear: we establish our 10 Community Red Lines early and unambiguously. If C G Fry and Chapman Lily Planning integrate these binding Section 106 Heads of Terms, certified nutrient neutrality, and highway solutions into their final submission, the development can achieve compliance with the statutory test of sustainable development. If they refuse or attempt to dilute these obligations through viability loopholes, this policy matrix provides the Wiltshire Council Planning Committee and Planning Inspectorate with an unassailable legal basis for planning refusal.
Environmental Philosophy: Stewardship vs Commodification
At the heart of the Parish Council’s advocacy lies a clear philosophical distinction between speculative land commodification and genuine ecological stewardship:
First formulated in the Brundtland Report (Our Common Future), sustainable development means meeting present needs without stealing from the future. Converting open chalk downland into asphalt is irreversible; once built upon, that rural heritage is gone forever.
Where serious environmental harm threatens chalk streams or groundwater, the burden of proof rests entirely on the developer. We do not accept assumptions that drainage will work when water tables rise without empirical winter boreholes.
Land is not merely an investment asset on a balance sheet; it is a living ecosystem supporting chalk hydrology, biodiversity, and community well-being that must be handed over in a healthier condition than we found it.
Why the Parish Council Is Engaging the Community in This Manner
A critical question many residents ask is: "Why is the Parish Council building this platform now, when there is no current Village Plan or adopted Neighbourhood Plan?"
The Planning Vulnerability: The "Tilted Balance"
Under the UK planning system, when a parish does not have an adopted Neighbourhood Development Plan (NDP) allocating specific housing sites, commercial developers can exploit this vacuum by lodging speculative planning applications. If the local planning authority’s housing land supply is challenged, national planning policy triggers the so-called "presumption in favour of sustainable development" (NPPF Paragraph 11), tilting the decision in favour of approving unallocated greenfield sites.
1. Levelling the Technical Playing Field
Housebuilders deploy multidisciplinary teams of planning barristers, transport consultants, and drainage engineers. Without access to technical tools, local communities are often out-resourced. This portal gives every resident instant access to professional-grade planning evidence and policy benchmarks.
2. Creating an Authoritative Evidence Base
General emotional objections carry very little weight with planning inspectors. Material planning representations citing specific Wiltshire Core Policies, groundwater records, traffic hazard observations, and Habitats Regulations carry decisive legal weight.
3. Securing Binding Section 106 Heads of Terms
If development cannot be prevented, our community must extract the maximum legal benefits: 30% local cascade affordable housing (18 units), surgery funding, continuous footways, and freehold public open space. We define our terms before the application is submitted.
4. Democratic Unity & Collective Voice
By gathering structured survey data from across Codford St Mary and St Peter, the Parish Council represents the unified, verified will of the entire village at Wiltshire Council planning committee hearings.
