For your information in the review of this applicationyou are advised as follows: 1. By my signature below set forth I certify that theproperty included in the sketch plan is owned, in fee simple,by fron Mountain Investments, Ltd. , a Colorado limitedpartnership and that the Bank of Grenwood, Glenwood springs,Colorado, currently holds a mortgragee's interest in thesubject property. 2. The total development area is . B0 acres as depictedon the sketch map submitted herewith. 3. It is proposed that the four-unit apartment buildingcurrently located on the subject property be divided intofour (4) condominium units. 4. The domestic water needs of the four units would beestimated to be not more than 1400 gallons per day whichneed is more than adequately supplied by the exempt domesticwell described on the statement of Beneficial Use and thepump installation report submitted herewith. 5. The four units are served by a septic system engineerdby a registered professj-ona1 engineer and property permit.ted and inspected by the Garfield county sanitarian, ar1 as morefu1ly set forth in the letter and permit submitted herewith.
