The plat proposes to gain access from a cul-de-sac off of Alpine Drive NW. This would meet city standards for Cul- de -Sac length and right-of-way width. The access proposed is satisfactory to staff. Septic/Drainfield. The current plan proposes each of the four lots to have individual septic systems. The Planning Commission has determined that individual septic systems will be acceptable for this development, but desires the recommendation of the Environmental Policy Board on this topic. Wells. The locations of the proposed wells have adequate spacing relative to drain field locations. Park Dedication and Trail Development Fees. Per the approved Master Park Agreement, Park Dedication and Trail Development Fee obligations have been satisfied. The agreement approved by the City Council on December 8, 2015 must be executed prior to filing of the Final Plat. Stormwater Trunk (Management) Fee. A Stormwater Trunk Fee in the amount of $459 per lot is due on the project. The total trunk charge shall be $1,836 for the project per 2016 Rates and Charges. Additional Improvements/Trail. There is currently a trail running immediately to the north of the proposed subdivision. In complying with the Parks, Trails, and Open Space plans for the City, proposed subdivisions should connect to existing trail systems. The proposed trail between lots 2 and 3 which connects with the existing trail within Northfork complies with those plans. Recommendation. City Staff is recommending that the Planning Commission approve the Preliminary Plat, with the considerations listed in this staff report. Next Steps. The Preliminary Plat Review process affords the Planning Commission to opportunity to provide more detailed direction on the layout of the proposed plat, before the Developer finalizes development plans and prepares the Final Plat. You will be required to enter into a Development Agreement with the City to ensure the timely construction of required improvements. The Development Agreement will also require a financial surety in the amount of 125% of the cost of required improvements. The financial surety shall be in the form of a Letter of Credit or cash escrow only. The Development Agreement will also require an Engineering Inspection Fee of 5% of the cost of required improvements. The escrow must be in the form of a cash escrow. The City will prepare a draft Development Agreement for your review. This will occur as part of approval of the Final Plat.
