This chapter establishes regulations for the recognized scenic areas within the city, the character of which could be permanently damaged by actions involving the development and use of land without special regulations to prevent or mitigate such damage.

All uses and structures permitted in the underlying zone shall be subject to the same conditions and restrictions of such zone and the following:

A.

The improvement of the building site either initially or after a principal use has been established shall not involve alteration of the surface of the land by construction, excavation, filling, or otherwise, through which trees would be removed, water courses would be altered, or earth banks exceeding 3 feet in height would be created unless the development is first submitted to and approved by the Planning Commission.

B.

Insofar as feasible, natural topography, vegetation, and scenic features of the site shall be retained and incorporated into each proposed development. The design of the foundation and structure for each proposed building shall accommodate the natural terrain with minimal grading. All other uses of the land including swimming pools, parking areas, etc. shall be subject to the general requirements for buildings.

Irrespective of the minimum size requirements for lots as provided in the underlying zone regulations, the width and depth of lots shall be increased by the total average width plus height of any earth cut or filled slope steeper than 4 feet high to 1 foot base adjacent the side lot line/s for increase of width or adjacent the front or rear lot lines for increase in depth.

All building sites shall be landscaped and maintained. In connection with each proposed development a landscaping plan shall be submitted with application for building permit. Such plan shall show location, size, and type of all trees proposed to be removed together with the size, location, and type of all trees proposed for replacement. All specimen trees shall be replaced with healthy trees also of specimen size except where this requirement is relieved by the Planning Commission upon justification.

All natural or created earth slopes shall be provided with a permanent underground irrigation system. All disturbed earth must be planted to control the erosion. All vegetation on either artificial or natural slopes shall be maintained.
