<br />8 <br /> <br />Thus, the Conceptual models appear to be the more appropriate <br />rainfall-runoff models for use in small to medium size rapidly growing <br />communities. Their predictive capability is as good as the Physically- <br />based models, yet they are generally less expensive to initiate and <br />support. Just as important, the Conceptual models are more likely to <br />yield consistent runoff response predictions regardless of model user. <br />This consistency is extremely important when the chosen model will be <br />" 'I: <br />accessed by various model users in the community such as municipal staff <br /> <br />. <br /> <br />personnel and engineering consultants. As a final consideration, the <br /> <br />community should endeavor to select a flood hydrology calculation method <br /> <br /> <br />that is consistent with other rainfall-runoff prediction models used in <br /> <br /> <br />the area. <br /> <br />Financial Element of the Drainage Management Program <br />The recommended Financial element provides for a sharing of the <br />costs to provide necessary drainage facilities. This method of financ- <br />ing raises three questions which were answered through an analysis of <br />pertinent case law: <br />1. Among whom should the costs be shared? <br />The costs can be shared among the municipal government <br />and land developers. The developers' responsibility for a <br />portion of the costs arises because they actually construct <br />the houses and roads that modify the hydrologic response of <br />the basin. The municipal government's responsibility stems <br />from its actions on subdivisions and annexations which allow <br /> <br />development to occur. <br /> <br />, <br />
