Agricultural land expected for commercial use - long narrow plot

The question is, do you want later a commercial property that you want to keep yourself to build on yourself or sell in 10 years. Or do you want as much money as possible. If you or the community do not want, your property will not be divided/changed. If it is changed, be careful with the tax.

instead of 300m x 10m, for example 30m x 100m.

That would really be a feat.

The property is located exactly in the middle of the area and the development costs have already been communicated to us.

We want to sell the property after development, it has belonged to us for 30 years.

Then think about who would want to buy such a strip - even if it is developed - and at what price. Then, upon serious consideration, you will say: No, no one wants the land alone. Maybe for consolidation with a neighboring property. But then the neighbor only needs 50m of the 300m length. Then the hassle with surveying, price finding, and processing arises.

Yes, such a small green space does every area good. And in private hands, the city doesn't even have to maintain the dog park. For commercial use, where a driveway, vehicle fleet, or parking area belongs to a building, hall, or pavilion, with a distance of 3 meters, i.e. a maximum building tax of 4 meters, the attractiveness is not really there, is it?
