What Surrounds A Pond

Zusammenfassung und Bewertung der Schall- und vibration-technical investigation 11.09.2009

Thomas Werner Neubauer
zoning ABS Leipzig-Dresden
section Neucoswig - Radebeul-West

Status: 02.12.2009


input data / legal basis


compared with the originally . now planning the following position changes are planned:

· increase the track level by more than 0.5 m from km 12.96 - 13.06 GB (Dresden-Elsterwerda) – 100 m im Bereich der Brücke über die Neucoswiger Str.

Bereits im PFV (Planfeststellungsverfahren) 1996 war eine Lageänderung um mehr als 1 m hor i zontal im Bereich 13,119 – 13,252 DE (Etwa auf Höhe der Schweizer Str.) vo r gesehen.

Diese beiden Bereiche wurden jetzt zu einem durchgehenden Abschnitt von km 12,96 – 13,27 DE zusammengefasst, der die Kriterien des „erheblichen baulichen Eingriffs“, as in the 16th BImSchV (Traffic Noise Ordinance) defines met.
were only for this area as a limited line source calculates the noise emissions from the surrounding moun e following plots, the emissions of the other sections do not matter, since there is no "major structural intervention" takes place.

The data base was used back on the line occupancy forecast of 1996 for 2010 z u . Usual in such proceedings are forecast horizons of 10 to 15 years (see expansion of Königsbrück Street in Dresden: withdrawing the application because a traffic forecast for 2025 is awaited).

results / further rechtl. bases


After the following calculation of the noise exposure at the affected Geba u the / land examined whether intervention by the building at the places a noise level change of more than 3 dB (decibels) results (Only then is entitled to a noise, otherwise existing policy covers the route).
That in any of the calculated Immissionorte the case.

Provided by the forecast, however, a immission of more than 60 dB at night (22-6 Clock) and this is enhanced by the construction project only by 0.1 dB, A is n entitled to protection against noise.

This criterion applies to the investigation of 9 houses to the west of the path.

Lämschutzwand Then, a 3-m and 260 m on the west side of the embankment from km 12.85 to 13.11 U.S. (the Neucoswiger Street is about 13 km) is proposed.

vibrations from the railway


forecasting methods for vibrations caused by rail traffic, there does not appear. It is therefore the implementation of evidence measurements on residential Lachenweg 2a vo r beaten (comparison before and after). This building is proposed because it is very close to the route lies and "two main floors and a habitable attic" has (in the noise prediction, it only happens with 2 residential floors!) and "as most Erschütteru n gene usually in the attic auftr e ten ".
If "a essential increase the vibrations ... result, then, in each case decided on appropriate remedies "

any shortcomings of the report - Conclusions


· The buildings Lachenweg 2a and Oststr. 1, the occupied floor was not considered, which should Approximate lead to an increase in properties with noise of return of 9 to 11 and also allows conclusions on the quality of the report, the 2a elsewhere (page 19 above) the building Lachenweg as an example for the Durc h guidance regarding evidence safeguards shocks recommended, n on the grounds training that the two main floors and a b e living Release Top floor has.
· The noise emissions were exemplary of land on both sides of the line calculated for the zero-and scenario (without active noise control). For the realization of the previously e proposed noise barrier only west of the route but were only the Immi s to the west of the line emissions calculated lying buildings. A calculation of the I m missions east, especially at the hospital, taking into account the reflections of an n -side noise barrier missing .
·        Dies ist insbesondere deshalb bedeutsam, da am Krankenhaus Immissionen bis zu 66 dB im Nachtzeitraum (Grenzwert nach 16. BISchV 47 dB !) und eine Erhöhung der Immissionen im Vergleich Nullfall zu Planfall von –0,1 bis 0,0 dB berechnet wurden. D.h. bei einer auch nur geringfügigen Erhöhung der Immissionen hätte das Fachkrankenhaus Anspruch auf Lärmschutz.
·        Der Neubau des Krankenhauses wurde als Immissionsort offenbar nicht berücksichtigt, ve r probably because its construction was not requested when the applications for PFV 2006th But if there is a change to the plans which - in contrast to the previously i gene planning - leading to a "substantial structural intervention," is, in my Rechtsauff a tion to take into account the new development as stock.
· The vibrations from the railway: The term "significant increase" is not defined. Nor is it clear who decides when the Remedies and the manner in which period this workaround has.
· original building noise and vibration: The report contains to 6 lines, which refer to the planning decision in 1999. The project since we r not taken into account, although the now planned removal and Repositioning des Dammes zwangsläufig zu deutlich über den bisher geplanten Umfang hinausgehenden Emi s sionen (auch Staub !) führen wird. Z.B. ist nach wie vor unklar an welcher konkreten Stelle die erforderliche Sieb- und Mischanlage betrieben werden soll. Da dieser Betrieb lt. Au s schreibung vsl. über mehr als 12 Monate erfolgen soll, wäre auch die Erfordernis einer i m missionsschutzrechtlichen Genehmigung zu prüfen.
·        criticism of the forecast horizon should be used cautiously in my opinion, as the track n occupancy in recent years has been on the decline, in my observation. When a new forecast anticipates low train numbers, would possibly also the right to larch m protection into question. On the other hand, sees the old forecast as ICE trains is entirely absent.
