10.1 Monitoring Measures
The monitoring measures proposed in this section refer to the significant effects that have been predicted to result from measures included in the Provisional LTP. However the monitoring programme itself will not commence until the Final LTP is adopted in March 2006. By then the monitoring requirements may have changed, either as a result of changes to the plan or due to other external influences on the baseline situation.
There is the potential that a shared SEA monitoring framework will be considered across the WMMA. This may influence the monitoring arrangements for the LTP.
Some monitoring measures are described below in Table 10-1. These measures are likely to require alteration as the plan develops. Any such alterations will be documented in the SEA Statement, see Section 11.
The measures in Table 10-1 can be augmented by other measures, based on the SEA Indicators. These are listed for each SEA topic in the tables of Appendix F.
Table 10-2 shows a framework for an implementation plan for monitoring. The activities in this table will be decided after:
- The monitoring measures in Table 10-1 have been finalised; and
- The responses from consultees have been evaluated, and any changes to the mitigation measures in Chapter 9 have been made.
The monitoring implementation plan will be published in the SEA Statement, alongside the Final LTP in March 2006.

Other monitoring measures could include such indicators as:
- Noise levels at sensitive receptors (e.g.; houses, schools and hospitals)
- Levels of use of recycled aggregates
- Achievement of Biodiversity Action Plan targets where these relate to transport
Measures could also be less quantitative, and could include, for example, monitoring to ensure that any Environmental Impact Assessments of major schemes incorporate the recommendations made in the SEA.
Example of a monitoring plan that could be developed for inclusion the SEA Statement is shown in Table 10-2.
