A combination of similar circumstances may be required to cover all proposed land uses. Approximately the square metres of the different focal uses of the pilot projects should be compared to the proposed project, so that the conditions of use can be assessed accordingly. In case of extension or replacement of existing uses, surveys document the use of the existing parking facility. Provide a maximum number of parking spaces on the road in an area. (2.) An agreement should be concluded which ensures that the owner makes the additional space available directly or by paying a replacement fee if, after a thorough examination of the actual use of the parking spaces on the building, the city recommends modifying or cancelling the permitted reduction within two years of the first occupation of the planning commission. . . .
