In order to minimize the number of site retaining walls that the sloping topography necessitates, we have designed all units to be either daylight or tuck-under. This allows us to integrate almost all of the walls into the foundations of the buildings themselves and produce a superior concept that will maximize natural light, views and the pedestrian experience of the sloping site and it's open spaces. This approach necessitates the consolidation of the on-site subgrade infrastructure improvements into a single excavation phase along with the building foundations themselves. After conversations with City Staff, it is our intent to construct the project in one continuous construction phase, and to directly follow mass excavation with the installation of the on-site vault, building foundations, as well as all on-site utilities, prior to back-filling and rough grading the site for vertical construction and surface improvements. Two concepts discussed to date include early approval of foundation installation and expanded bonding to allow vertical construction to commence prior to final plat approval. The benefits of a consolidated construction phase are multifold: construction impacts to the neighborhood are minimized, and the physical disturbance and potential for construction related erosion is greatly reduced by avoiding a second excavation phase for building foundations. We are looking forward to open communication with Staff about achieving this important goal for the project and community: 1. Preliminary PUD and Preliminary Plat: June 2017 - November 2017 2. Construction and Final Engineering Plans: August 2017 – December 2017 3. Building Permit Review and Approval: August 2017 – December 2017 4. On & Off-Site Infrastructure Development: Starting in April 2018 5. Vertical Townhome Construction: Starting in June 2018 6. Townhome Sales: Starting in Spring 2019
