Concurrent with making the permit application, the party desiring the permit must deposit a sum equal to one‑half of the estimated cost of engineering and superintendence as determined by the City Administrator except that when a consultant does the design and survey the deposit will be 20 percent of the estimated cost of engineering and superintendence. This deposit must be determined by using the appropriate schedule of services found in Section 17.24.070. All deposits must be made prior to any design work being done by the consultant. In the event that no permit is issued for the proposed improvement within one year from the time design and plans are reviewed and completed, the City will retain the amount of the deposit as compensation for the preparation of design and plans or efforts of review. If a permit is issued for the proposed improvement within one year from the time such design and plans are completed, the amount of the required deposit will be applied to the cost of the permit fee for such improvements.
