The development is located on the southwest comer of the intersection of State Highway No . 6 (East Bypass) and University Drive. The proposed development is essentially zoned all as C-B with 20 .59-acres ofR-5 . The site is currently unimproved with native grasses, weeds, and light underbrush and heavily vegetated with large trees . The natural drainage of the site is generally to the northeast to Burton Creek at a point near the confluence of Carter's Creek. The elevation range of the project site is from 260 to 300 ms!. The Gateway de v elopment water system shall be tied into the existing 12 " PVC water line that dead ends on the north side of University Drive and loop back to the existing 16 " water line near Lot 3 , Block One of this development. This water system will be designed to support the proposed projected improvements . The proposed water system will be sized to provide adequate domestic supply and fire flows . PROJECTED DEMANDS 1. DOMESTIC SUPPLY -The Gateway development water system was evaluated during the projected normal conditions for the supply of domestic water use and consumption . These demands are based from the zoning of each lot within the development. 000300-3199 Hydraulic Analysis.doc Hydraulic Analysi s - 3 Th e Gateway Water Improvements Muni ci pa l Develo pm ent Group NORMAL FLOW CONDITIONS ::1~1.iii~{ ii i,;liii ! !!ll~ii i!lill !lillllif1;1 1i;,11: ::1:1:11:1:11in~lilllll ::1::: 1 C-B 26 .51 39,765 36.82 119,295 110.46 2 C-B 3.34 5,010 4.64 15,030 13 .92 3 C-B 1 .15 1,725 1 .60 5 ,175 4 .79 4 C-B 1 .77 2,655 2 .46 7,965 7 .38 5 C-B 1.32 1,980 1 .83 5,940 5 .50 6 C-B 1.70 2,550 2 .36 7,650 7 .08 7 C-B 1 .49 2,235 2 .07 6,705 6 .21 8 C-B 1 .88 2,820 2 .61 8,460 7 .83 Res .

Daily Flow • 24 Hour Usage Period • Peaking Factor of 3.0 2) Commercial (C-B) • 30 Persons I acre • 50 GPD I Person@ Avg . Daily Flow • 18 Hour Usage Period • Peaking Factor of 3 .0 2 . FIRE FLOWS -The Gateway development water system was evaluated during the worst case scenario of providing fire flow protection . Fire flow conditions will be assumed to produce 2,500 gpm from any two adjacent fire hydrants . CONSTRAINTS The Texas Natural Resource Conservation Commission (TNRCC) publishes criteria for the design of water hygiene in Chapter 290 of the 30 Texas Administrative Code (TAC). This design criterion provides specific parameters for the designed and operation of water systems . Based on these criteria, The Gateway development water system was design , with respect to current regulations . 000300-3 I 99 Hydraulic Analysis .d oc Hydraulic Analysi s - 4 The Gat ewa y Water lmprovements Municipal Developm ent Group 1. DOMESTIC SUPPLY -The water system shall have the capacity to supply peak demand while maintaining a minimum residual pressure of 35 psi . 2 . FIRE FLOWS -During fire fighting conditions, any fire hydrant or combination of hydrants within the tolerable distance shall provide the required capacities will maintain within the system a minimum residual pressure of 20 psi . Hydrants shall be located so they are visible and accessible . Fire hydrants shall be installed in this system so that no structure shall be more than 3 00 feet from the fire hydrant as measured along the right-of-way or firelane as the fire hose is laid of the fire truck. SYSTEM MODELING The hydraulic study was analyzed with the aid of Water CAD ver. 1.0 . The model uses the proposed mapping to create a theoretical simulation of the system . The theoretical demands are based upon full occupancy conditions for domestic supply . During fire flow conditions, the theoretical demands are negated and the fire flows are imposed upon the system. The pressure at the point of connection with the existing 16" water line was determined by the flow test conducted on April 8, 1999 . The flow test conducted by the City of College Station on the fire hydrant at the intersection of Glenhaven and University yielded a pressure of 92 psi . Gerald Kubica supplied the flow test results . RESULTS The Gateway development water system will consist of a 12 " and 8" PVC system of water/fire line loop tying into the existing 12" and 16 " as mentioned earlier . This system is as shown on Plate #1 -"Proposed System Mapping". The enclosed hydraulic study data shows that the proposed development water system can be tied into the existing City of College Station water lines and provide adequate pressures and water flows . 000300-3199 Hydrau li c Analysis .doc Hydrauli c Analysi s -5 The Gateway Water Improvements Muni cipal De velopm ent Group Domestic Supply 3 .48 85.51 98 .01 N/A Fire Flow Synopsis # 1 9 .11 84 .10 94 .43 #1 &#2 Fire Flow Synopsis #2 8 .16 83 .47 94 .17 #2 &#3 Fire Flow Synopsis #3 9.73 83 .47 94 .36 #3 &#4 Fire Flow Synopsis #4 9 .12 81 .88 95 .70 #2 &#5 Fire Flow Synopsis #5 9 .10 79 .17 96.92 #5 &#6 Fire Flow Synopsis #6 10 .82 83 .53 97 .64 #6 &#7 Fire Flow S o sis #7 9.19 81 .22 97.32 #6 &#8 000300-3199 Hydrauli c Anal ys is.doc Hydrauli c Analysi s -6 SECTION#l MAPPING SECTION#2 WATER SYSTEM CALCULATIONS (DOMESTIC SUPPLY) Project Title: Gateway development i :\projects\300\3199w1 ra .wcd 06/16/99 04:30:10 PM Steady State Analysis J-4 P -4 RESERVE A J-3 P-3 RESERVE B LOTS LOT?

Thanks! Page 1 f File Memo Date: September 20, 1999 To: File ~ From: Jeff Tondre, P.E. Afr{ ( Development Engi ~r,,g RE: Gateway Phase I Water and Sewer On the afternoon of Tuesday, September 14, 1999, Natalie Ruiz and I met with North Bardell, P.E. and Greg Taggart in their office to discuss construction plan requirements for the above listed project. This meeting was in response to a letter dated September 3, 1999 from Jane Kee and myself regarding tree preservation requirements and fire flow demands. The meeting started with Mr. Taggart objecting to using a portion of the parking requirements of the Zoning Ordinance with regard to water line location. Ms. Ruiz stated that per the city 's Zoning Ordinance, Qll trees 4 " and greater in diameter must be preserved within the 24-foot landscape reserve. Mr. Mihalopoulos was informed in writing by Jim Callaway on July 20 , 1999 (See attached letter). Mr. Taggart continued to disagree with this requirement. He stated that he spoke with Ross Albrecht who stated that it would be better to plant new trees. We repeated that the Zoning Ordinance required that the existing trees must be saved and further discussions regarding this issue would need to be with Jane Kee, the City Planner in charge of zoning . We also discussed the issue regarding fire flows. Mr. Taggart stated that he was not sure what type of development was going to occur in the back portion the property . We stated that if we did not know what type of development could occur, that the lines should be sized for the maximum potential development expected for the area based on current zoning. Mr. Taggart stated that they sized the line for "reasonable " development. I re-iterated the need for Mr. Taggart to get the fire flow rates approved by Jon Mies, Fire Marshal. I also stated that if the fire flow analysis showed that a 12" waterline was not needed by this development under University Drive and to the loop system in the development, that I would forward an over-sized participation request for City Council for consideration upon request. Mr. Bardell indicated that the owner requested that the sewer and water plans be approved separately. He did not think it was appropriate, nor would the city approve separated plans. I stated that it was unusual, but we would consider it. There would have to be special notation regarding additional requirements that may be necessary regarding utility conflicts that may result.

Box 9960 VIA FACSIMILE (972) 233-1501 Dear Frank, 1101 Texas Avenu e Tet. 409 764 3500 College Stat io n , TX 77 842 Staff has received several inquiries recently concerning The Gateway property at University Drive and the Highway 6 East Bypass. As you recal~ a condition of the C-B Commercial Business zoning on the property is to provide a tree survey. At the time of rezoning, the Planning and Zoning Commission as well as the City Council were concerned with maintaining an aesthetically pleasing entrance to the City. One major factor was the preservation of existing trees, especially within the first 50' of the University Drive frontage. Since that time, the property was cleared by heavy equipment in direct violat ion of the Development Permit. Staff chose not to pursue legal action; instead, the remaining trees will only be allowed "unprotected tree" points as defined in the City's Zoning Ordinance. After reviewing the tree survey and discussing this issue with the City's Forestry Superintendent, staff has developed the following option for developing the properties along the University Drive frontage : Section 9.2.A5 requires that there be a 24' landscape reserve setback from the right-of- way. Existing trees of 4 inch caliper or greater must be preserved. Because of previous clearing in this area, these trees will not be allowed protected tree P<>int credit, although they may count toward the street tree requirements under the streetscape requirements . Before any development permits or other permits will be issued, this 24' reserve must be fenced off so that no construction activity is allowed within the reserve. If you have any questions, please contact me at (409) 764-3570. ~ely, Jim Callaway Director of Development Services Home of Texas A&M University DEVELOPMENT PERMIT PERMIT NO. 609 GATEWAY FOR AREAS OUTSIDE THE SPECIAL FLOOD HAZARD AREA RE: CHAPTER 13 OF THE COLLEGE STATION CITY CODE SITE LEGAL DESCRJPTION: Northwest comer of University Drive East and the SH-6 By-Pass. 75.11 Acre Tract-Richard Carter Survey OWNER: Frank Mihalopoulos 4455 Alpha Road BLDG 2 Dallas, Texas 75244 214-535-7272 DRAINAGE BASIN: Burton Creek SITE ADDRESS: TYPE OF DEVELOPMENT: This permit is valid for clearing and grubbing as per approved plans.

In addition, Lot 4 has been previously disturbed and needs to be smoothed and reseeded. Portions of this work have been accomplished without benefit of a College Station development permit. The intent of this application is to bring the site back into compliance with local ordinance control. The owner desires to bring in approximately 20,000 cubic yards of additional clean fill material. The fill material is being imported from another job site that is currently under construction. Due to the time constraints associated with receiving the material, the scope of work on this site will be submitted in two phases, in an effort to expedite Phase I and allow ample review time for Phase II. Phase I The scope of work with the first phase will include: 1. Installation of a construction entrance on University Drive at the location shown on the "Gateway Storm Water Pollution Prevention Plan" hereinafter referred to as the "Plan". 2. Installation of tree preservation fencing (minimum of 4' high) along the 24 foot preservation area as shown on the "Plan". 3. Installation of silt fencing on the property as shown on the "Plan". 4. Stock piling of the fill material on Lot 1 as shown on the "Plan". Spreading, compacting and reseeding the disturbed areas will be performed under Phase II of this permit. Phase II The scope of work with Phase II will be to spread the stockpiled materials onto Lot 1, a portion of which will be within the 100 year floodplain. This Phase is not part of this request at this time. It will be submitted as an addendum to this plan in order to allow staff ample time to review the submittal and issue a subsequent development permit and still allow the site to receive the fill materials. If during the Phase II review, there are difficulties encountered with placing the fill within the floodplain, there is ample room onsite outside of the floodplain boundary where the fill can be spread, compacted and reseeded. All stormwater pollution prevention measures from Phase I will remain in place until vegetation has been reestablished which will occur with Phase II. With Phase II, the owner also agrees to replace 4 -6" caliper trees in the area of the construction entrance once it is removed. The owner also agrees to replace any trees that cannot be adequately barricaded adjacent to the construction entrance (adequate is defined as the tree barricade must extend to the drip line of the tree) with the same number of trees at a 6" caliper size. These trees will be tagged once the tree barricade is installed and a final count of replacement trees will be submitted to the Oty. The timing of installation of the trees will be once the hydromulch activities as part of Phase II are complete. ITEM NO. 4211 ·FILTER FABRIC FENCE PART 1 -GENERAL '\ 1.01 Description This .

Site Description The Gateway Subdivision is located on the north side of University Drive just west of SH 6 Bypass in College Station, Texas. A portion has been previously deared of the natural vegetation. The current zoning on the property is C-8 with an av overlay. With this, there is a 24 foot tree preservation area within the property adjacent to the University Drive right-of- way. II. Scooe of Work The property is currently vacant and the owner desires to bring in fill material to place on Lot 1, Block 1. In addition, Lot 4 has been previously disturbed and needs to be smoothed and reseeded. Portions of this work have been aa:omplished without benefit of a College Station development permit. The intent of this application is to bring the site back into compliance with local ordinance control. The owner desires to bring in approximately 20,000 cubic yards of additional clean fill material. The fill material is being imported from another job site that is currently under construction. Due to the time constraints associated with receiving the material, the scope of work on this site will be submitted in two phases, in an effort to expedite Phase I and allow ample review time for Phase II. Phase I The scope of work with the first phase will include: 1. Installation of a construction entrance on University Drive at the location shown on the "Gateway Storm Water Pollution Prevention Plan" hereinafter referred to as the "Plan". 2. Installation of tree preservation fencing (minimum of 4' high) along the 24 foot preservation area as shown on the "Plan". 3. Installation of silt fencing on the property as shown on the "Plan". 4. Stock piling of the fill material on Lot 1 as shown on the "Plan". Spreading, compacting and reseeding the disturbed areas will be performed under Phase II of this permit. Phase II The scope of work with Phase II will be to spread the stockpiled materials onto Lot 1, a portion of which will be within the 100 year floodplain. This Phase is not part of this request at this time. It will be submitted as an addendum to this plan in order to allow staff ample time to review the submittal and issue a subsequent development permit and still allow the site to receive the fill materials. If during the Phase II review, there are difficulties encountered with placing the fill within the floodplain, there is ample room onsite outside of the floodplain boundary where the fill can be spread, compacted and reseeded. All stormwater pollution prevention measures from Phase I will remain in place until vegetation has been reestablished which will occur with Phase II. With Phase II, the owner also agrees to replace 4 -6" caliper trees in the area of the construction entrance once it is removed. The owner also agrees to replace any trees that cannot be adequately barricaded adjacent to the construction entrance (adequate is defined as the tree barricade must extend to the drip line of the tree) with the same number of trees at a 6" caliper size. These trees will be tagged once the tree barricade is installed and a final count of replacement trees will be submitted to the Oty. The timing of installation of the trees will be once the hydromulch activities as part of Phase II are complete.

(Second letter sent to clarify tree survey requirement and outside display in the C-B zone) To Whom It May Concern: This letter is to clarify certain conditions required for development of the above referenced property. The property was rezoned in 1995 with certain conditions as follows : 1. Access d ri ves to the property shall be limited to o ne driveway off the By- Pass Frontage Road and one driveway off of University Drive. Please refer to the enclosed map for approxi mate driveway locations . These locations were approved as part of the Council adoption of the University Drive Study and comply with the City 's Driveway Access Policy. The City's Driveway Access Ordinance will help you determine exact driveway locations . 2 . · Cross access shall be provided within the development among all future lots . Note that ~he extension of Glenhaven Drive across University Dr. through this property is on the City's adopted thoroughfare plan. Internal access should be oriented to this roadway. 3. A landscape buffer shall be provided between the subject property and the existing R-1 property in the northeast comer. At a minimum this shall consist of a solid screen fence with landscaping adjacent. This will be review at the time of site development. 4. A sewer impact study shall be conducted at the time of development to determine whether there is enough capacity in the existing system to handle the proposed development. 5. Prior to C-B zoning being effective a tree survey shall be conducted and submitted for (ieterminat ion of tree preservation . This survey should identify nati ve trees of 8 inch caliper or larger within the first 50 feet of the University Dr. frontage. The survey should include this frontage along University Dr. adjacent to the R-5 zoning as well. 6 . Any additional costs relating to turning lanes or medians associated with a new traffic signal at Glenhaven shall be borne in part by the developer. This will be discussed at the time of site development . Any deviation from the above conditions would r equire a rezoning request. Home of Texas A&M University I have forwarded a request for a letter regarding utility availability to the City's Division Manager for Water and Wastewater, Bill Riley . He may be contacted at 764-3660. Floodplain reclamation shall be reviewed under the City's Drainage Ordinance. The question was asked whether floodplain reclamation here will fall under the same regulations as the pending Carter Creek Relocation project. Both projects must comply with the City's drainage ordinance. The ordinance does call for a longer review time for projects located in the Carter Creek tloodway. The creek located on this property is Burton Creek and the ordinance allows for a 10 day review of proposed plans when submissions are complete and no variances are requested. As Burton Creek is an interjurisdictional creek shared by the City of Bryan, as a courtesy all reviews shall be forward to the City of Bryan . All development within the Burton Creek basin has a mandatory detention requirement of 100 year ultimate developm ent. The C-B zoning district allow some outside display of merchandise (for sale only and not storage). The merchandise shall be within 50 feet of the building and not in the parking lot nor closer than 50 feet to any street frontage. I hope this addresses all of your concerns and clarifies what is necessary for the City to help you accomplish development of this property. Sincerely, e R.

The subject property includes most of the vacant property extending from the Highway 6 Bypass to the developed properties off of Spring Loop. Staff recommends approval with the following conditions: -that the access points be limited to one drive off of the Bypass frontage and one drive off of University, -that cross access be provided, -that there be a landscaped buffer between the proposed C-B and the R-1 to the north, -that a sewer impact study. be provided at the time of development (not necessarily at the time of zoning) discussing the impact of the proposed development on the existing sewer infrastructure both onsite and offsite, thus determining the necessity of improvements to the system to handle the increased flows generated from this rezoning. These improvements will be the responsibility of the developer, and -that a tree survey be conducted and submitted for the purposes of native tree preservation. The request is in compliance with the University Drive Study that was adopted by Council in 1991. The Study recommended an extension of the existing commercial area to make that site more usable and to avoid a strip commercial effect. The rest of the property was to be evaluated using Development Policies, which would support R-5 adjacent to commercial. The study also discussed the potential for sewer capacity problems in the area and the difficulty that would arise as development pressures increased and rezonings were requested which include high sewer generating uses. There are plans for sewer capacity improvements to the University Drive corridor, however they have been placed on hold as more critical areas in the City are being addressed. While there is ample vacant C-B and R-5 zoning in the City under current market conditions, the Future Land Use Plan for the area supports this request. Therefore, the requested zoning fits into the overall plan for the development of the City. COUNCIL POLICY ENDS STATEMENTS -The following Ends Statements that are in bold are relevant to this particular case. There are no Ends Statements that specifically address housing. Transportation/Mobility: Citizens benefit from the ability to move within College Station -the development plan includes an extension from Glenhaven Drive through the subject property Parks & Recreation: NA Health & Public Safety: NA Education/Information: NA Quality Service: NA Cultural Arts: NA Employment/Prosperity: NA Civic Pride: Citizens benefit from a well-planned community -the request represents a comprehensive approach to zoning. COMPREHENSIVE PLAN -The following are Goals and Objectives from the City's adopted Comprehensive Plan . Applicable ones are in bold. Complies with Future Land Use Plan Map?: Yes Development Goals and Objectives: LAND USE Protection of residential uses: The only affected residential area is the R-1 piece that will be left over once the requested zoning is in effect. Staff recommends a buffer in the form of a landscaped easement to be installed as a condition of development. Encourage use of vacant land w/ services: NA A void strip commercial: The request meets location criteria o f siting commercial at major intersections and following a step-down approach. The requested depth meets Development Policies relating to commercial development. TRANSPORTATION Provide major arterials to prevent congestion: The development plan includes a possible future connection between Glenhaven and College Station. Staff has had discussions with Bryan regarding the connection, and Bryan has subsequently reflected the connection on their Thoroughfare Plan . Adequate pedestrian/bike movement: NA Ensure safety and ease of maintenance: NA Location of streets based on function: The site is located at the intersection of two major arterials. Driveway access: The University Drive Study recommended driveway access from one point off of the frontage road and one point along University Drive in addition to the future street extension. ECONOl\flCDEVELOPMENT Compatible with environment: NA Encourage retirees: NA Encourage tourism: NA PARKS AND RECREATION Parkland dedication or fees in lieu of dedication will be required for the multi-family development at time of site plan review. Link parks by pathways and natural features: NA Combine parks with schools: NA 2 HOUSING Maintain integrity of existing supply: The recent interest in multi -family development in the City has resulted in a total of 850 apartment units that have been added to our housing supply since mid-1993. Single family housing starts have been very strong since early 1990. The result has been a relatively balanced proportion of single-family to multi-family units, despite the recent surge in multi-family construction. The rezoning to R-5 will open up the potential for roughly 560 multi-family units . However, rezoning the property does not mandate an immediate development of that land. At some point in the future , College Stat ion will need this many apartment units to balance growth , and the requested location presents a reasonable use for the land. Encourage diversified housing: NA COMMUNITY APPEARANCE Promote good site design: Most of the area requested for C-B is located in the Overlay District, which has increased setbacks for buildings and parking, and controls over building and signage colors. Good site design will be ensured through the site plan review process. Prevent and eliminate unsightly conditions: NA HISTORICAL OVERVIEW - The subject tracts along with those properties with frontage along University Drive from the Bypass to Tarrow were a part of a special study that was conducted in 1991. The recommendations that came out of that study were adopted by Council as a guide for future zoning decisions. The Study recognized the area as having a high potential for commercial development for most of the University Drive frontage, but it clearly stated a desire to have development occur in an orderly and attractive fashion. Two subsequent actions were taken to implement that plan: 1) creation of the Overlay district and 2) creation of the C-B zoning district. The Overlay district left underlying use classifications alone but added aesthetic controls over site development. Most of the property included in the subject tracts is already located within the Overlay district. The C-B district was created as an alternative to C-1 in an effort to further preserve the physical attributes of this entrance into the City. Uses that tend to benefit from attractive and well-controlled sites were included. The Study specifically discussed this area , recommending a fairly large C-B area to be surrounded by compatible land uses. This request is in line with that study. 3 ENGINEERING COMMENTS AND IMPACT STUDIES- Water -Water is available to the area through a 16" waterline along University Drive. Extensions will be required within the site to serve the area. Sewer -Sewer is available through 2-12" sewerlines. One along SH 6 Bypass and the other along the north property line. Both of these lines ultimately tie into a 21" sewerline that runs along Carter Creek. The rezoning to R-5 and C-B will increase the amount of sewer flow to these lines. Capacity may be a problem due to the potential intense sewer uses allowed in C-B and R-5 districts. Streets -See comments in the Transportation section above. Traffic -See comments in the Transportation section above. Drainage -Drainage design will have to comply with the City of College Station Drainage Ordinance. Will be reviewed at the time of platting or site plan. Flood Plain -There is extensive floodplain located on this property which will have to be addressed at the time of site development. Sidewalks -Sidewalks will be required along University Drive and may be required on interior streets, depending on development scenarios. These will be required at the time of platting or site development.

Box 9960 RE: NOTICE OF NONCOMPLIANCE 1101 Texas Avenu e Tet. 409 764 3500 With: Chapter 13 , City of College Station Code of Ordinances Site: Gateway Phase I College Station , T X 77842 March 10, 2000 Location: Northwest corner of University Drive East and the SH-6 By-pass Dear Permittee, It has come to our attention that your development site is not in compliance with your development permit and Chapter X of the Drainage Policy and Design Standards , as adopted through Chapter 13, § 3.B of the City of College Station Code of Ordinances . Chapter X requires the implementation of measures necessary to prevent the movement of sediment, by erosion or action of man from areas undergoing development or construction, onto adjacent properties, streets or into any part of a drainage system. This Chapter is enforced by ensuring that development and construction sites implement standard Best Management Practice(s) (BMPs) to prevent sediment transport. Typical BMPs appropriate for this site include, but are not limited to: daily removal of sediment transported from the site, properly installed silt fencing, installation of rock berms in locations of concentrated flow, and wash-down areas for vehicular traffic. Similar requirements are necessary under the Federal Clean Water Act to be eligible for coverage under the NPDES General Construction Stormwater Permit. This nationwide permit requires that a log of inspections, maintenance, and spills must be kept on-site . This log should be made available to City staff upon request. City officials visited the site this morning and found the silt fencing previously installed was not installed properly, is not being maintained , and is no longer performing its intended function. In addition, fill material is being placed near the fencing perimeter creating a worse condition than would normally occur. Ms. Veronica Morgan was contacted this morning regarding these issues . Appropriate action must be taken immediately to bring this site into compliance to ensure the health , safety and welfare of our community . If action on your part can not reasonably be taken immediately, please provide written documentation of the item not implemented, the reason for the delay, and the expected time frame for implementation. Failure to comply with this City Ordinance will result in enforcement action taken in accordance with Chapter 13 , § 7 of the Code of Ordinances . Home of Texas A&M University If you have any questions or do not understand any of these requirements, please call me at (979) 764-3570 . Thank you for you cooperation .
