§ 1

The subject of the edit

(1) this Ordinance lays down technical requirements for the construction for the performance

forest functions, which are the construction of forest roads, buildings cover the streams and

ravines, building drainage of forest land and small water reservoirs in the Woods.

(2) pursuant to this order shall be followed when designing, positioning,

work or changes to the structures referred to in paragraph 1.

(3) the provisions of the special law shall remain unaffected. ^ 1)

§ 2

Definition of basic terms

(1) for the purposes of this order means for building forest roads

and) forest path (hereinafter referred to as "the way")-targeted communication

part of the forest road network, designed to transport timber, transport of persons and

material only in the interests of the owner of the forest and for the passage of a special

vehicles. Allows safe year-round or seasonal operation,

(b)) the ground path-several layers of differently processed construction

materials that their overall design ensure load carrying capacity for the operation of

the design of the vehicle,

c) longitudinal tilt of the road trip-a move away from the horizontal surface

the plane in the direction of the alignment of the path indicated in the preparation,

d) transverse tilt of the road trip-diversion of surface or part of a path

from the horizontal in the transverse cut indicated as a percentage,

e) class dates-sort character common to the paths of the same transport

importance in terms of the forestry operation, it is the importance of transport and

the purpose of the trip (class 1 l up to 4 l),

by sliding or jumping. Tiny particles floating in the water are


(d) special shore-vegetation-) vegetation plant communities, in particular

herbal remedies and dřevinných stands on the banks of watercourses and reservoirs, which

protects banks against vymílání water and at the same time performs other functions, in particular


(e)) by modifying the catchment area torrent-file specifying the measure into conformity

economic, cultural and other forms of exploitation of the basin with the protection

soil, hydrological cycle, nature conservation requirements and the requirements for

habitability of the territory,

(f) design flow-flow rate), which is used for the design of water

works to flood protection of the downstream areas.

(3) for the purposes of this order means for drainage of the forest land and buildings

small water reservoirs in the Woods

and zamokřením forest land)-humidity affecting the forest and grassland culture

caused by the waters of the přitékajícími surface or underground tributary or

the waters of the detainees on forest land,

(b)) a small water tank-building, allowing the largest backwater in which

flooded area is 2 ha and whose purpose is the retention of water in the

forests, affecting the water regime in the forest soils in the vicinity of the tank protection

drainage network before an accelerated water erosion and to ensure water supplies in

sites at risk of forest fires,

c) outlet-the object specified for controlled discharge of small water tank and

drainage of its dna,

d) sauce-an object used to safely convert a design flow

and to the protection of small water tank before it is congested.

§ 3

Requirements for the construction and equipment

Construction for the performance of functions of the forest must be designed and constructed so that the

they were respecting the economy suitable for the intended use, and

at the same time meet the requirements for mechanical strength and stability,

safety in use, protection of the environment ^ 2), and the use for

the purpose of fire protection territory. ^ 3)

§ 4

Requirements for the construction of paths

(1) the travel route is proposed to meet the requirements of sound

forest management and its protection, the least disruptive to the forest stands,

podchycovala what the largest area of forest and fully conforms to the direction and

the inclination of the route.

(2) the largest longitudinal gradient for new roads with the road is 12%.

(3) the value of the transverse inclination of the road and the plains of the path is on a new path, or

When you change the current path of at least 3%.

(4) the width of the odlesněného bar for a new path, or when you change an existing

the trip will be limited to compliance with the parameters for the design of the route of the path chosen by the


(5) the longitudinal and transverse drainage body journey captures and drains

threatening solid or surrounding land podmáčením or water erosion.

In particular, the use of ditches, culverts, bridges, gravel, crash barrier, and


(6) the smallest luminance pass is 600 mm.

(7) Descents of the paths on the adjacent land must have a width of at least 6 m.

(8) the passing Bay are part of the journey and shall be intermittently in places with

sufficient views, which makes it safe for avoidance and overtaking.

Suggest 1-2 passing for 1 km length of the path. The minimum length of the passing

It is 20 m.

(9) the inflow of rainwater with the surface of the road or local path

communication must prevent the drainage of waters referred to in paragraph 5.

(10) it is not permitted to use vehicles of greater weight on

remedy than that for which it was built, the path using the path at a time

When is not eligible for operation (seasonality), or in a way that for a given

type of trip is not taken into account (e.g. sliding wood road).

(11) the reclamation of the paths is always performs, is resolved in the area of forest

the right to permanently in another way.

§ 5

Requirements for the construction of the payment streams and ravines
