Box 9960 College Station, TX 77840 Re: Terrace Pines Apartment Homes Dear Bridgette, Attached is a site plan for the Terrace Pines Apartment Homes which illustrates a product for elderly housing. We have several issues we would like to discuss at the upcoming Pre - Application Conference. They are as follows: 1. Currently the site is not parked per ordinance. Ordinance requires 1- 1/2 spaces per bedroom and we are parked at 1 space per bedroom. Y We would like to apply for a parking variance for this based on the clientele who will be living here. 2. ` We currently have 4 dumpsters on the site and we would be required to have 6 dumpsters per the UDO. Again we would like to apply for a variance to this regulation based upon our clientele. 3. We have 2 buildings that are located at a 45* angle to Krenek Tap . Road. We are unsure if this orientation meets the requirements of the overlay and would like clarification to that issue. 4. We currently have one building that is oriented with it's side to Krenek Tap Road and we will be rotating that so that the front door 0 is oriented to the street. 5. We have a front porch on each unit, which we believe meets the ordinance but would like clarification of the wording "usable ,porch" in an effort assure that the depth is sufficient. Our current depth is approximately 8 feet. 6. We realize that the rear setback as drawn is incorrect and that it must be increased to a 20ft. setback. We will be calling Krenek Tap Road the front and measuring front setback from there and Dartmouth will be considered a side street setback. 7. We would like to have a master water, electrical and gas metering system. This development does not resell these utilities to these customers. Rather, they have a flat rental rate in which utilities are included. The owner has experience with this product and assures us that these units do not produce the parking and trash requirements of conventional multi- family housing. Thanks for your time and please call if you have any questions. Sincerely, oel I itchell, P.E.

The following are our responses to the Site Plan Comments for the Cotten Subdivision. PLANNING: Comment: Because the project is located within the Krenek Tap Overlay, the architectural design of all building facades facing Krenek Tap Road have to meet the requirements of Section 5.8.C.2 of the LIDO. Please submit the architectural elevation and description of materials to be used on the facades. Answer: Excerpts of the architectural drawings (Sheets A2, A7, A8, and A10) showing these details are included in this submittal. Comment: The property owner named on the site plan (Dean Ranch Properties, Ltd.) should match that on the application. Answer: The property owner named on the site plan has been revised to match the application. Comment: Please provide more information on the gates (e.g., swing path, entry system.) Also, there should be a gate along the fence line by Building 2 for pedestrians to move from the internal sidewalk system to the public sidewalks. The swing path of the security gate should not meet with the sidewalk. Answer: The development shall use linear pull gates as the site plan has been revised to show. The pedestrian gate has been added. 511 UNIVERSITY DRIVE EAST, SUITE 204 COLLEGE STATION, TX 77840 • T 979.260.6963 • F 979.260.3564 CIVIL ENGINEERING • HYDRAULICS HYDROLOGY UTILITIES • STREETS - SITE PLANS • SUBDIVISIONS info @mitchellandmorgan.com www.mitchellandmorgan.com Comment: Please describe the material(s) used for the perimeter fencing.

Answer: The notes are shown on sheet L3.3. Trees that are not barricaded are shown color outlined while trees that are barricaded are shown colored solid. Comment: There is concern that some of the trees to receive protected points will not be able to be barricaded at 1 " per 1' because of their proximity to proposed drive aisles, sidewalks, and buildings. While they may be protected to the extent possible, you may wish to reconsider claiming these as "protected" trees. Staff will examine the barricades before clearing and grading and during construction. Answer: Noted. Comment: Streetscape requirements for Dartmouth are 4530 points and 24 trees. The points have already been covered by the existing plan, as have 12 trees. Twelve more canopy trees are necessary (or non - canopy trees substituted at 1 canopy: 2 non - canopy). Answer: The canopy tree requirement has been met using a combination of canopy and non canopy trees. Note that on the plans, the plantings used for calculating the Dartmouth Drive streetscape requirements have a "D" next to the planting and the plantings used to calculate the Krenek Tap streetscape requirement have a "K" next to the planting.

Assistant City Engineer for Development Development Services P.O. Box 9960 College Station, TX 77840 RE: Terrace Pines Apartment Homes —Water and Sewer Analysis Dear Spencer: Below is the analysis of the water and sewer lines within the Terrace Pines development. The normal flows for both water and sewer were calculated using method 2, land use determination, as found in the February 2004 B /CS Unified Design Manual. Flows calculated using this analysis can be found in Exhibit A. Water Sizing: The Terrace Pines Apartments contain 100 units (56 one bedroom and 44 two bedroom units), with 4 units to each building. 60 units will be serviced by an eight inch (8 ") waterline off of the future Dartmouth Drive, and the remaining 40 will be serviced by an additional eight inch (8 ") waterline off of Krenek Tap Road. The Dartmouth Drive waterline will require a 1 inch water meter, and the Krenek Tap Road waterline will require a 3/ inch meter. Meters for the two lines were sized using American Water Works Association guidelines. The largest building on the development consists of 4 two bedroom units, with a total of 3,800 square feet. The units are not sprinklered and are of construction type V -B, requiring a fireflow of 1750 gpm per the 2000 International Fire Code, as shown in Exhibit B. Because the development is to be serviced by two waterlines, a fireflow of 1750 gpm was put on the hydrant at the end of each line. MikeNET analysis found that two eight inch (8 ") radial lines will be sufficiently large to serve the entire Terrace Pines development. Flows in the waterlines were kept below 12 fps and pressure remained above 20 psi, as per the February 2004 B /CS Unified Design Guidelines Manual. Results of the MikeNET analysis may be found in Exhibit C. The waterlines serving the Terrace Pines Apartments are not looped; the TCEQ requirement for looping is clearly stated as required for circulation of water. Although the waterlines dead -end into the development, there is no stagnation in this design due to a water meter at the end of each line. This configuration was chosen because of the quantity of water line required: less than 500 feet of water line is required to provide fire protection but 1100 feet of water line is required to loop the system and the cost to loop the waterlines greatly exceeded the cost to build the current design. 511 UNIVERSITY DRIVE EAST, SUITE 204 COLLEGE STATION, TX 77840 • T 979.260.6963 • F 979.260.3564 CIVIL ENGINEERING • HYDRAULICS HYDROLOGY UTILITIES • STREETS • SITE PLANS - SUBDIVISIONS Info@mitchellandmorgan.com www.mitchellandmorgan.com Sewer Sizing: 84 of the 100 units will be sewered by a six inch (6 ") sanitary sewerline across Krenek Tap Road. The peak flow from these units is 62.3 gpm. The remaining 16 units, with a peak flow of 11.9 gpm, will be sewered by the existing eight inch (8 ") sanitary sewer line along the western property line. The new sanitary sewer line was sized using the Manning's equation, as shown below, modified to solve for diameter. 3 S D _ 3.21Qn 1.49S 2 Manning's "n" was assumed to be 0.013; Q is the flow into the pipe in cfs; and S is the slope of the pipe, assumed as the minimum allowable slopes per the February 2004 B /CS Unified Design Guidelines Manual. Although calculations show that the flow generated from these units only requires a two inch (2 ") sewerline, a six inch (6 ") diameter sewerline based on College Station's wastewater design standard pipe sizes was chosen.

Of course, the "required fire flow" is for a single structure, single fire event. One 1750 demand is all that is required. It has been our opinion that a fire flow report should not be approved solely based on modeling. Field fire flow/ hydrant data is readily available and should rule over modeling. Please let me know if I can assist is obtaining hydrant data and how we can incorporate this into your report. Also, your water layout does not include the 12 -in along Dartmouth... no biggie actually but the report should be accurate. thx st Spencer G.
