. >> good evening my name is brian lafco and i'm the architect on the project.down into three basic aspects. first is the impact on the rear open space and already reported to the planning staff and design team -- you can see this is the site plan of the existing conditions. where in the existing situation, there is 63% of the yard is uncovered by structure. and this includes a large concrete terrace, or hard scape of the rear yard area. our proposal effectively replaces the hard scape with the new addition, resulting in non-hard scape portion of the yard being exactly as the yard today at 42% and when compared to the joining properties the resulting open yard is by far the most open among them. you can see that the drr is 33% and we would be at 42%, 23, 17, 30, and 9. the second aspects of their complaint is privacy. the dr's two-story wall looms over my client's as seen in this image. as well as seriously impacting views for everybody beyond my client's house for many, many years as you heard the age of building. can see right here the red-dotted line approxim
