9. Lieut.-Colonel Sir ARNOLD WILSON
asked the Minister of Agriculture which, if any, of the arterial roads completed in the past 10 years are as yet fully set out on ordnance maps of 25-inch, 6-inch and 1-inch scales; whether details of any of the new housing estates in Hertfordshire, Surrey, or Essex are similarly recorded; and whether he is aware of the expense and delay to local authorities with statutory housing and town-planning obligations consequent upon the backward state of the Ordnance Survey?
§ Mr. ELLIOT
About 90 per cent. of the arterial roads completed in the past 10 years are shown on the 1-inch scale Ordnance Survey maps already published, or in course of publication. No such roads are shown on the 25-inch or 6-inch scale maps except those in the close proximity of some of the larger towns. 25-inch and 6-inch maps of Surrey will be published shortly, which will show about 75 per cent. of the details of new housing estates in that county. The new housing estates in Hertfordshire and in Essex are not shown on the 25-inch or 6-inch maps for those counties, but will be shown on the new edition of the one-inch maps. These sheets will be published almost immediately, probably before the end of February. The desirability of speeding up the revision of Ordnance Survey maps is receiving my close attention.
