Purpose and stages

The purpose of the planning stage is to identify and support a proposal to decision makers to establish continuous and integrated management of the coastal and marine area. Three sub-stages are identified: data collection, policy development and decision making.

Data collection

First, a coastal profile must be prepared. This is an overview of all (natural, social, engineering, institutional and management) characteristics relevant for the problems at hand for the given area. The World Bank (93) gives the following list of items that should be covered:
  • Coastal Resource Base
  • Social Organization in the Coastal Zone
  • Existing Environment and Resource-Related Programs
  • Institutional, Legal, and Financial Capacity

The coastal profile leads to a detailed formulation of the problems and the information gaps that still need to be filled.

The Kastela Bay Coastal Profile

Natural characteristics: The Kastela Bay is located at the central part of the Croatian coast on the eastern part of the Adriatic Sea. The area encompasses the Kastela Bay and the neighbouring Split and Brac Channels, as well as the associated coastal strip. The coastal plain around the bay is 1-3 km wide, covering approximately 14,500 hectares.

Socio-economic conditions: The total population of the narrow coastal area has tripled over the past half a century, reaching 284,000 inhabitants in the year 1991, while the estimated population for the year 2015 will be 355,000. Split is the second largest town of Croatia. 

Institutions and management: Ministry of Environmental Protection and Physical Planning is the supreme administrative body in charge of the organization of environmental protection and sustainable development in the Republic of Croatia. It prepares the laws related to environmental protection, monitoring and the state of environment.


Policy Development

Second, based on the profile, a policy must be developed which is the core of the ICZM process written down in the ICZM program. This document gives:
  • the precise definition of the area considered: the coastal zone. Such a boundary may be based on physical processes, biological processes or on existing legal frameworks,
  • the goals of the ICZM program: A good management program has well defined goals to prevent it loosing its impulse,
  • the strategies: The goals should be accompanied with several alternative policies which are evaluated with respect to their success of attaining the goals (see also the Policy Analysis module),
  • a description of the proposed institutional arrangements, including assignment of responsibility for various parts of the programs,
  • funding and staff requirements, and
  • a list of the formal actions necessary for official adoption of the plan and a suggested timetable for completing these.

Decision Making

Finally, the ICZM program must be accepted by the decision-makers and formally adopted. Chances of timely approval are increased if the program (Cicin-Sain et al., 1998)
  • uses clear and understandable terms
  • describes the benefits in tangible and meaningful terms
  • is endorsed by all stakeholders
  • is known to key politicians which have received regular updates on the ongoing process of its formulation
  • illustrates the involved costs and ways to cover them.

Long-term solution of the sewerage system in the Kastela Bay. The map shows the area around Trogir.

The long-term solution of the sewerage system, developed on the basis of a detailed analysis of ecological, technical and economic parameters, envisages the construction of two separate sewerage systems, one for the Split - Solin area and a separate one for the Kastela - Trogir area. Each system is of a separate sewerage type, consisting of a sewerage network, collectors and pump stations, a central waste water treatment plant, and a corresponding submarine outfall.


General objectives of the National Project “Environmental Management of the Kastela Bay” were, by application of scientific methods, to:
  • identify the causes of the present situation and trends;
  • assess their impacts and significance; and 
  • develop alternatives for sustainable development.
Specific project objectives were as follows:
  • to define the sensitivity, vulnerability and (limited) carrying capacity of the natural resources;
  • to introduce standard procedures and parameters in the process of management of natural resources; and
  • to apply, within the project scientific framework, an integrated approach and principles of sustainable development.
The area of Kastela Bay is under administration of four municipalities, province and relevant ministries. For the purpose of the Integrated Ecological Project, ECO-Kastela Bay agency was founded by the 4 municipalities and the Government of Croatia through the relevant institutions. The main task of the Agency is, on behalf of its founders, to prepare and implement the agreed projects of common interest. The Agency represents its founders in front of investors and banks, and implements the project according to the conditions posed by the creditors and the founders. 

The envisaged water supply system.The map shows the area around Trogir.

The water supply project envisages additions to and spreading of the existing water supply system which includes the construction of a central pumping station, four smaller regional pumping stations, 17.5 km of water supply pipelines, and four reservoirs of various capacities, as well as an appropriate management system.
