b) A lack of coordination of the structures of different investors in a given locality (the issue of so-called “overlaying”, technical standards, the need to change or renew a land use decision, protection and safety zones). c) Unresolved possibility for sharing passive infrastructure suitable for establishing electronic communications networks (lack of awareness about the existence of usable passive infrastructure, the absence of conditions for its sharing, etc.). d) Unreasonable requirements for the subsequent treatment of surfaces of the land in question over and above what is essential (the original or an appropriate state). e) Disproportionate deadlines for the occupancy proceedings for communications networks structures (this also applies for other utilities). electronic f) The placement of internal communications lines and the conditions for their potential sharing are not adequately addressed in the applicable legislation and technical standards. g) The complexity and slowness of the process for expropriating property rights necessary for the placement of electronic communications networks (in particular the demonstration of public interest, the unique nature of the technical solution, the scope of documents required). 4.3.2 Financial barriers a) The one-time compensation for the establishment of easements is not demanded as standard by property owners according to a unified methodology. In particular, the demands of government authorities, local government and enterprises with state or local government ownership often exceed the market value of the property. In addition to one-off financial compensation unreasonable requirements are often exercised in the form of non-monetary performances, e.g. returning the surfaces of the land in question beyond the framework of restoration to their original (or a corresponding) state. b) The amounts of fees demanded for the use of open public space does not correspond to the level of temporary aggravation of the use of the open space in question for the needs of electronic communications networks in the public interest. c) The legislation regarding responsibility for municipal management does not adequately enable municipalities to require a one-time compensation for the establishment of an easement for a lower price. d) The long periods for the tax depreciation of constructed networks reduces possibilities for private investment. 4.4 Investment models for support and business models for the development of NGAs 4.4.1 Investment models and the selected investment model for the development of NGAs The selection of the most appropriate investment model is crucial for the fulfilment of the determined objectives; its determination was based on the material Guide to High-speed 28
