3 Introduction UK housing pressure - Overall decline of house building in the UK - Steady population growth - Increasing house prices Increasing demand Limited supply Source: Office for National Statistics, The Telegraph 3

4 Introduction National Planning Policy Framework Local Plan must allocate sufficient land to meet housing requirements Site selection methodology Staged approach Implementation using GIS 4

5 Site Selection Methodology Spatial analysis Spatial analysis Stage 1 Major policy constraints Stage 2 Quantitative and qualitative assessment 800 sites 50 criteria Assessment Proforma Stage 3 Identify candidate preferred sites Spatial analysis Stage 4 Deliverability assessment Assessment Proforma Portfolio of site allocations 5

6 Site Selection Methodology Spatial analysis Stage 1 Major policy constraints Qualitative assessment Spatial analysis Stage 2 Quantitative and qualitative assessment Assessment Proforma Moderation workshop Stage 3 Identify candidate preferred sites Officer workshop Member workshop Qualitative assessment Spatial analysis Stage 4 Deliverability assessment Assessment Proforma Officer workshop Member workshop Portfolio of site allocations 6

7 GIS Requirements / Challenges Central data store Flexible spatial analysis - Data updates - Changes in methodology Webmap editing Mobile data collection Visualisation of results - Summary of assessment results in Proformas - Maps 7

8 Central Data Store Central Data Store SQL database ESRI Enterprise Geodatabase Multiuser editing Hosted in own network Single source of truth Security/access levels Domains ensure data quality Desktop Users ArcGIS Server/Portal Mobile Data Webmap Users 8

9 Flexible Spatial Analysis 30 GIS assessments across stages: - Standard spatial analysis - Network analysis - Raster analysis Each assessment results in a score for each site Examples of criteria are: - Flood risk - Air quality - Open space - Distance to public transport Sites GIS Assessment Score Criteria (++) (+) 0 (-) (--) 9

10 Flexible Spatial Analysis Automation using Python (arcpy) Consistency in methodology 10

11 Webmap Editing ArcGIS Server / Portal Data edited by different stakeholders User-friendly No GIS software required Removed redundancy Live updated data Greater transparency in sharing of information Topic specific maps 11

12 12 Webmap Editing ArcGIS Server / Portal

13 Mobile Data Collection ArcGIS Collector ios / Android devices Data synced on central data store Pre-defined input forms to assess attribute information - Dropdowns - Date fields Drawing of polygons Photo attachments 13

14 Visualisation of Results - Proformas 500 sites for Stage 2 Data driven pages Overview and zoom maps Dynamic table using attribute information Rule-based text fields Color-coded boxes (-) (--) Site is not located within or adjacent to Ancient Woodland. Site lies outside of areas identified as being poor of air quality. Site is more than 4000m from the nearest rail or tube station. Majority of the site is greenfield land that is neither within nor adjacent to a settlement.
