GEOLOGICAL AND GEOTECHNICAL DATA AND LAND USE PLANNING. MAPPING OF "ZERMOS" RISKS APPLIED TO LAND USE PLANNING IN NORMANDIE

DONNEES GEOLOGIQUES ET GEOTECHNIQUES ET PLANS D'OCCUPATION DES SOLS - CARTOGRAPHIE DES RISQUES ZERMOS APPLIQUEE A DES PLANS D'OCCUPATION DES SOLS EN NORMANDIE

AFTER RECALLING THE PRESENCE IN FRANCE OF "ZERMOS" (ZONES EXPOSEES AUX RISQUES DE MOUVEMENTS DU SOL: ZONES EXPOSED TO RISKS OF SOIL MOVEMENTS) AND THE METHODOLOGY DEVELOPED FOR MAPPING THESE ZONES ON A 1/25000 SCALE, THE AUTHORS STUDY THE APPLICATION OF THIS WORK TO LAND USE PLANNING, TOWN PLANNING DOCUMENTS OPEN TO OBJECTION BY THIRD PARTIES, WHICH LAY DOWN GENERAL RULES GOVERNING LAND USE. EXAMPLES OF THIS APPLICATION ARE GIVEN CONCERNING TWO LAND USE PLANS BEING SET UP IN ZONES WHERE NATURAL SLOPES SHOW SIGNS OF INSTABILITY IN NORMANDIE. ON THE WHOLE THE METHODOLOGICAL PRINCIPLES OF ZERMOS MAPPING AT 1/25000 REMAIN VALID BUT THE SCALE NEEDS TO BE ADAPTED, THERE SOMETIMES ARISE DIFFICULT PROBLEMS OF LIMITS BETWEEN DANGER ZONES, AND THE QUESTION OF THE COST OF THESE STUDIES HAS TO BE TAKEN INTO ACCOUNT. THE RESULT IS A "POS (LAND USE PLAN) - ZERMOS" MAP BASED ON A LAND SURVEY, WITH ADDITIONAL GEOTECHNICAL RECOMMENDATIONS TO WHICH THE LAND USE PLANS MUST CONFORM.
