The Local spatial development plan for the Sierpc-Zachód [Western Sierpc] area covers a fragment of the western part of the city of Sierpc. A railway line, with a station located in the east-central part of the study, around which the development areas are concentrated, runs through the area of ​​the plan. The construction areas in the plan are compact blocks of extensive single-family residential buildings and mansions, as well as areas of multi-family residential buildings, served by a developed, hierarchical street network. The areas located in the western part of the plan were designated for extensive functions, including cultural and tourism services – an open-air museum. The character of other valuable open areas, i.e. agricultural and forest areas, was preserved.
