Ministry of Agriculture
of 3 December 2001
laying down technical requirements for forest performance structures
The Ministry of Agriculture provides pursuant to § 143 (4) (b) and (c) of Act No. 50 / 1976 Coll., on Territorial Planning and Construction Regulations (Construction Act), as amended by Act No. 83 / 1998 Coll., Act No. 151 / 2000 Coll. and Act No. 254 / 2001 Coll.:
Subject matter
(1) This decree sets out the technical requirements for the construction of forest functions, which are the construction of forest roads, the construction of byproducts and drains, the construction of the drainage of forest land and small water tanks in forests.
(2) According to this Decree, the design, placement, authorisation, notification, implementation, approval, use, maintenance or modification of the structures referred to in paragraph 1 shall be carried out.
(3) The provisions of the specific legislation are not concerned by this (1)
Definition of basic terms
(1) For the purposes of this decree, the term "forest buildings' means:
(a) forest route (hereinafter referred to as "road") - a dedicated road which is part of a forest transport network intended to carry timber, transport of persons and material only in the interests of the forest owner and for the passage of special vehicles. Allows safe year-round or seasonal operation,
(b) by the road - several layers of different construction materials which, by their overall construction, guarantee the loading capacity for the operation of the design vehicle;
(c) by the longitudinal slope of the road - the deflection of the road surface from the horizontal plane in the direction of the road station, as a percentage;
(d) by the transverse slope of the road - the deflection of the road surface or part thereof from the horizontal plane in the transverse section indicated as a percentage;
(e) journey class - a sorting sign common to roads of the same transport importance in terms of forestry, that is the transport importance and purpose of the journey (class 1L to 4L),
(f) year-round operation - operation on a journey without a time limit;
(g) seasonal operation - operation along the way in time periods defined by a relatively dry period or a frost period;
(h) plain of the road - treated surface area intended to establish the road;
(i) reclamation routes - activities which remove the journey or its residues due to its further unusability and, at the same time, adjust forest parcels damaged by road traffic;
j) by means of a pass - an object with a vertical aperture of up to 2 m, including for transverse draining,
(k) deflection - one-sided widening of the path by the width of the lane intended for avoidance or overtaking.
(2) For the purposes of this Decree, the following definitions shall apply to the construction of bystander and rafters:
(a) by paying for byproducts and drains - a systemic combination of forestry technical measures for river basins, directing economic activities with a view to water retention and flooding, increasing the intake, preventing rapid erosion or the subsequent removal of flood damage;
(b) seabed - terrain groove or pothole formed by concentrated surface drainage of water;
(c) floods - particles moved irregularly through the water stream either by shifting or by jumping. The tiny particles floating in the water are swimmers,
(d) coastal vegetation - the purpose of growing plant communities, in particular herbaceous and woody crops on the banks of watercourses and ponds, which protect the banks against water dissolution while at the same time fulfilling other functions, particularly ecological ones,
(e) adaptation of the water catchment areas - a set of measures to bring the economic, cultural and other ways of using the water catchment areas with soil protection, hydrological cycle, nature conservation requirements and land habitability requirements;
(f) design flow rate - flow rate to be applied to the design of waterworks for flood protection of the downstream territory.
(3) For the purposes of this decree, for the construction of the drainage of forest land and small water tanks in forests:
(a) contamination of forest land - moisture causing damage to forest cultures and crops caused by water coming from surface or groundwater or retained on forest land;
(b) a small water tank - an airframe which allows the largest flooded area not exceeding 2 ha and whose purpose is to contain water in the forests, to affect the water regime in the forest soils around the tank, to protect the drainage network from accelerated water erosion and to ensure the supply of water at sites threatened by forest fires;
(c) discharge - an object intended for the controlled discharge of a small water tank and drainage of its bottom;
d) overflow - an object used to safely convert the design flow and to protect the small water tank from overfilling it.
Requirements for construction and installations
The construction works for the performance of forest functions must be designed and carried out in such a way that, while respecting the economy suitable for the intended use, they meet the requirements for mechanical resistance and stability, safety in use, environmental protection (2) and for use for fire protection purposes (3).
Requirements for road construction
(1) The route shall be designed in such a way as to meet the requirements of proper forest management as well as its protection, as little as possible to disturb forest crops, capture as much forest area as possible and fully suit in the direction and slope of the route.
(2) The largest longitudinal slope for new roads with ground is 12%.
(3) The value of the transverse slope of the road and the plain of the road is at least 3% for the new route or when changing the current route.
(4) The width of the deforested lane for the new route or when changing the current route is limited to meeting the parameters for the route design of the selected class.
(5) The longitudinal and transverse drainage of the road body captures and drains waters threatening the body or surrounding land by soaking or water erosion. In particular, ditches, rigols, passes, bridges, manholes and trativores are used.
(6) The smallest clearance is 600 mm.
(7) Departures from roads to adjacent parcels must be at least 6 m wide
(8) The switches are part of the journey and are set up irregularly in places with sufficient views to allow safe avoidance and overtaking. 1 to 2 switches per km of path length are proposed. The smallest length of the switch is 20 m.
(9) The influx of precipitation water with road surface or local communication shall be avoided by drainage in accordance with paragraph 5.
(10) It is not permissible to use vehicles with a mass greater than the permissible axle load for which the journey has been built, the use of the journey at a time when they are not fit for operation (seasonal) or in a way which is not considered for the type of journey (e.g. washing of wood on the road).
(11) The path reclamation shall be carried out whenever forest transport is permanently resolved in a different way in the area.
Requirements for construction of bystander and rafters
(1) The essential elements of the original route of the bristle or ravine shall be maintained as far as possible. Adjustments shall not prevent the use of adjacent land and shall allow maintenance of the enclosed sections as well as care for non-covered sections.
(2) The radius of the curves shall not be less than six times the width of the trough between the shore edges.
(3) If the buoyancy or ravine significantly or permanently condenses and deepens the trough, its resistance to the kinetic energy of water shall be increased by increasing its dimensions, reducing its longitudinal gradient or by fortifying it.
(4) The design flow rate for the trough capacity shall be determined taking into account the protected objects and cultures in the adjacent territory. It is necessary to assess where and why the highest flood level has reached historically.
(5) The closed profile shall be so dimensioned that at least 500 mm of open space remains above the surface with a design flow rate of at least 500 mm every 100 years and the flow is protected against obstruction. The closed profile pressure flow rate is not allowed.
(6) The purpose of the longitudinal fortification of the riverbed or ravine is to ensure the stability of the riverbed or its parts, that is in particular the stalk of slopes and shores.
(7) In the event that shore crops are designed for the longitudinal fortification of the riverbed banks, rich-spice trees shall be used.
(8) The highest height of degrees with the edge of the overflow at the level of the upper bottom is 1000 mm.
(9) Floods with an edge of the tide above the level of the top floor, with a storage or sorting compartment, are technically adapted to facilitate the migration of fish only if they are present in the section of the bristles or in the draught of their permanent occurrence.
(10) Systematic adaptations shall be carried out in sections with significant flow of flooding and in favour of the protection of settlements and real estate. Less costly measures are gradually supplemented according to the development of river basin drains and the state of the modifications made.
(11) The upper edge of the pipe (or its building protection) shall be placed at least 700 mm below the low bottom when the pipes are crossed with an unmodified sharp flow. When crossing the cable, its smallest depth is 1000 mm below the low bottom, at the communication cables 1,400 mm. The striations for storage are fortified in the bottom and in the slope of the trough after filling and compaction.
Requirements for construction of drainage of forest land and small water tanks in forests
(1) Before each drainage, the local conditions of the pedological nature of forest land, the causes of the contamination, the state of the crops and the cultivation objective, the restoration, cultivation and protection of the crops, the slope of the territory, transport accessibility, or water accumulation, shall be evaluated.
(2) The management of trench paths is dealt with by local conditions (sloping) and by reducing harmful effects on the forest with adverse wind flow.
(3) In determining the depth and gauge of ditches, account shall be taken of the biological requirements of the trees depending on the species and age composition of the trees.
(4) The draining ditches shall be designed in a longitudinal inclination of at least 0,5%, a depth of at least 600 mm and a gauge of at least 30 m (for detailed drainage).
(5) On contaminated areas of forest land, which do not offer a guarantee of success in their drainage (high cost, maintenance performance), perimeter ditches are built with the leaving the natural development of the water regime or converted into permanent water areas.
(6) The smallest distance when crossing underground cable lines below the bottom of the modified ditch is 700 mm for communication cables, 1,000 mm for electrical cables. If these distances are not observed, the cables stored shall be protected by strengthening the trenches at their location.
(7) The width of the crown of the dam on which the journey is made is determined by its design elements. In other cases, the free width of the dam crown shall be at least 3,500 mm.
(8) Each flow tank shall be equipped with an overflow to drain water for flooding and discharge. Pressure effluent is inadmissible.
(9) Tanks which are equipped with artificial contact and cannot be overloaded even in the event of a fault in the inflow need not be fitted with an overflow.
(10) The discharge shall allow the discharge of the water from the tank at any level and the complete release of the tank. The discharge shall be provided with at least one closure and the flow profile of the discharge shall not be less than 300 mm.
(11) The excess capacity at the highest level in the tank shall be at least equal to the flow rate with the frequency of occurrence every 100 years. At this flow value, the water level shall be at least 400 mm below the dam level.
(12) The banks of the tank and the slopes of the dam shall be protected against disturbances by fluctuating water levels, waves, ice-cold regions, or erosion of surface-draining water by grass, vegetation or building modifications.
Efficacy
This Decree shall take effect on 1 January 2002.
