MOUNTAIN HOUSE SPECIFIC PLAN II CHAPTER FOUR: DEVELOPMENT AND DESIGN 4.1 INTRODUCTION This chapter presents davelflpment and design plans standards and guidelines,iridludfng design concepts for focus areas, and states implementation measures for 5P11. The guidelines in this Specific Plan are intended to supplement the MHCSI]Design Manual. Lana use is addressed in Chapter Three: Land Use. Schools are addressed in Chapter Five and parks and open space issues are addressed in Chapter Seven. 4.2 0EVELOPMENT STA NI)ARIDS The overall objective for development standards is to provide a guide for all development within SPII and to assure a high level of quality al the construction and aperatinn of publiC and private buildings, open spaces and facilities. Unless addressed specifically, development standards shall be in accordance With the County Development Title and the MHOSD Development Standards. Standards for street rights-of-way are found in the MHSOD Development Standards. All implementing projects on land controlled by trJill aFkCQrnm�ir+ge -LLCthe Master Developer,shall comply with the applicable provisIons of the Trin;ar#c t^�ar�rF+daities-LLQ Mountain Rause design Manuals, as amended,as evidenced by written approVal from TFirnarkGoFnrntrnities Cthe Master Develover,or its Design Review Committee, in its sole discretion. Nan-Trimark properties shall also comply with these documents,which compliance shall be determined by San JoagWry County. 4.2.1 Grading Standards Master Plan Summary Grading practices within the community are to minimize disruption to the natural topography;protect srnd enhanr a the project's aesthetics;minimize risk to health and property from improper contral of storm drain water runoff,erasion and sedimentation; and provide for efficient construction operations. Grading will ensure positive drainage and weate areas that appear an integral part of the graded or paved surface with smooth slope transitions. Storrn water runoff will be directed towards public streets, public facilities or easements and not across adjacent private property. Grading operations will be planned and implemented to efficiently control erosion and sedimentation. Specific Plans will provide typical grading details and grading concepts for any spacial conditions unique to the particular Specific Plan area. Plan Description The purpose of grading is to facilitate the ability to implement Master Plan density targets, including a variety of lot and hame sores, and to ensure public safety through the enforcement of standard engineering design principles such as maximum grades of struts and allays, positive drainage,water quality management, and minimization of abrupt slope transitions. SPII areas with unique grading and drainage conditions consist of Neighborhood C and the lands north of Byron Road. In Neighbarhood C,the average existing grade across tht site is approximately 1.5%,with the landform sloping from an elevation of 165 feet in the southwest to elevation 85 feet in the northeast across a distance of approximately 4,804 CHANTER FOUR DEVELOPMENT AN0 DESIGN PAGE 4.1 Resolution Template 01/2017
