SENSIBAUGH, Public Works Director//'/" JGJ: fr/l/29/87 ! �� C:AGATA315 !/ 12 Exhibit A RESPONSIBILITIES OF CONSULTANT TASK 1 - IDENTIFY EXISTING CONDITIONS The first task in your project is to gather and review all existing information regarding the City' s sanitary sewer system and land use plan. We will work closely with City staff to collect information in one common format using ex- isting plans , reports, records , and discussions with opera- tion and maintenance personnel . 1 . 1 - PREPARE PROJECT METHODOLOGY Establishing the project methodology will be the first pri- ority of the project. The first step will be to meet with key City individuals in a workshop environment and discuss in detail the project objectives , determine the existing and future service area such as the ACSD or Urban Services Line and to what degree the City staff and others will be involved. During preparation of this proposal, we believe we understand what the City desires from the master plan design. During this workshop, CH2M HILL will work with the staff to develop an expansive decision tree . This decision tree will include the methodology of the master plan and will direct all future system evaluations . At the completion of the project, the City should then have the experience and capability to continue . 1 . 2 - REVIEW EXISTING INFORMATION In this subtask, we will collect and review available infor- mation regarding the Atascadero sanitary collection system including, but not limited to, maps , records , surveys , plans , construction drawings, topographic information, rain- fall records , groundwater data, maintenance records , and water consumption data. Specifically, the following shall be collected and carefully reviewed: o City of Atascadero - Capacity Analysis and Eval- uation of the ACSD Wastewater Treatment and Col- lection System prepared by John L. Wallace and Associates . o City and County Genera'_ Plan documents . o As-built plan. 0 1 " = 100 ' scale aerial mylars of the study area. r ' o Assessment district boundary information. c Properties with septic tank problems defined by San Luis Obispo County for Cease and Desist. o Locations and drawing for the 9 public lift sta- tions and each on-site private lift station. TASK 2 - REVIEW WASTEWATER FLOW DATA The most difficult task in evaluating an existing sanitary sewer system is development of realistic wastewater flows during dry and peak wet weather conditions . We will collect and review the historical monthly flow charts from the treatment plant. The treatment plant historical charts should also include flow data during several rain events . This data will be used to assess historical infiltration/ inflow (I/I) levels within the City and to compare water consumption with wastewater flows. Rainfall records that correspond chronologically to the historical flow records will also be collected. This flow information will be used for calibration of the computer model, to quantify I/I components , verification of land use flow rates, and to develop peaking factor curves . Our extensive experience in flow monitoring work has given us many practical techniques to reduce the flow and rainfall data . We have a complete computer library to reduce the data into a manageable form in a cost-effective and timely manner. Since development of our software is complete, Atas- cadero can benefit from our extensive experience at minimum cost. 2 .1 - DEVELOP RAINFALL-DEPENDENT INFILTRATION/INFLOW (RDI/I) HYDROGRAPH The first step in the analysis is to discern dry and wet weather flow conditions . The rainfall data collected during the monitoring period is used to accomplish this task . The next step in the analysis is to separate rainfall-dependent infiltration/inflow (RDI/I) from wet weather flow. RDI/I is the component of infiltration/inflow which enters the sani- tary collection system during and shortly after a rain event. The RDI/I component is the extra flow that causes the Atascadero flow to jump from 1 . 0 mgd to 3 . 6 mgd during peri- ods of rainfall. CH2M HILL has found that the quantity of RDI/I is highly dependent on antecedent soil conditions . As the soil be- comes saturated, more RDI/I can be expected. Although the presence of I/I is not considered to be substantial, the actual relative peak flow from each basin such as the older �✓' err+ downtown areas may be significant. The capacity analysis of the trunk sewer system must be conducted during saturated soil conditions when RDI/I is at a maximum. In addition to soil conditions, the amount of RDI/I is also dependent on the intensity and duration of each rainfall event. CH2M HILL has developed custom software which is capable of synthetically simulating the amount of RDI/I for any given design event. The final product of this analysis will be the design storm RDI/I hydrographs for the system. Depending on the magni- tude of this flow, the City may wish to conduct further flow monitoring of key locations in the collection system. CH2M HILL has conducted many flow monitoring studies specifically with the objective of isolating areas within a collection system contributing significant I/I . A flow monitoring pro- gram of this type would supplement your ongoing internal closed-circuit television inspection program to identify actual sources of I/I such as broken pipe, open or broken joints , roots , laterals, direct connections , etc. 2 . 2 - DEVELOP SANITARY FLOW ALLOCATION FACTORS Development has been categorized into three major land uses: o Residential o Commercial o Industrial CH2M HILL will review the sanitary flow allocation factors for each of these land uses specific to Atascadero. Res- idential and commercial categories will be further subdi- vided as detailed information is available. The industrial category is very minor within Atascadero . These unit flow values are not only .category specific, but also season specific. 2 .3 - CALCULATE GROUNDWATER INFILTRATION The treatment plant flow recorded during the rainy season when GWI is present will be reviewed. Groundwater infiltra- tion rates will be calculated by subtracting calculated sanitary flow from non rainfall flow recorded during the winter season. GWI = DWF - SF Where: GWI = groundwater infiltration, mgd DWF = monitored dry weather (winter) flow, mgd SF = sanitary flow, mgd 3 .3 - PROJECT LAND USE Based on the updated general plan document, future land use will be identified. The identification of future conditions can only be an estimate because of the political nature of the general plan document. We will work closely with your planning staff as well as with San Luis Obispo County to identify the projected development. Development projections beyond even 2 years can only be determined within a range. These projections shall be summarized in a Technical Memoran- dum and reviewed with the Citv. 3 . 4 - CALCULATE SANITARY FLOWS The existing and future sanitary flows will be calculated based on existing and future lard use data multiplied by the unit flow values from Subtask 2 . 2 , Develop Sanitary Flow Allocation Factors. The future flows will be calculated based on projected lard use for each development within the ACSD/Urban Services Line. The City' s current software and database (Lotus 123) will be utilized and expanded to include the future growth areas . TASK 4 - DEVELOP DESIGN FLOWS In this task, present and future design flows are developed for each predefined basin of the collection system. Design flows are the peak wastewater flow rates that are expected to be carried by system facilities after future development. These peak wastewater flows occur during wet weather peri- ods. During this master plan, design criteria shall be de- veloped to identify the following three components for peak wastewater flow: o Peak Groundwater Infiltration - The peak ground- water infiltration (GWI) rate for each basin will be derived in Task 2 , Review Wastewater Flow Data. A GWI allowance will be applied to currently un- serviced areas and major extensions of the City' s sewer system. o Peak Sanitary Flow - Sanitary flows generally fol- low regular diurnal patterns , with peak flows oc- curring in the morning and early evening hours of the day. Peak hour sanitary flows •:ill be esti- mated by applying a multiplier, called a peaking factor, to the ultimate development average sani- tary flow rates . The ultimate development average sanitary flow for each basin will be developed in Task 3 , Project Future Land Use. The peak hour a1 + sanitary flow will be calculated using the sani- tary flow peaking curve. o RDI/I Hydrograph - RDI/I hydrographs for each basin will be developed for a design rainfall event in Task 2, Review Wastewater Flow Data. An RDI/I allowance will be applied to currently ur_serviced areas and major e.:tensicns of the City' s collection system. Groundwater infiltration, peak sanitary flow, and rainfall- dependent infiltration/inflow will be combined to develop a design flow composite hydrograph for each sanitary basin and the future grcwth areas. The design flow hydrograph data for each basin will be used to analyze the existing collec- tion system, as described in Task 5 , Determine System Capacity. TASK 5 — DETERMINE SYSTEM CAPACITY The sewer capacity analysis will be performed with the use of computer modeling techniques . The hydraulic model STATIC, developed by CH2M HILL, will be used to predict and simulate flow in the wastewater collection system under various load- ing rates . 5 . 1 - INVENTORY MAJOR TRUNK SEWER SYSTEM An inventory of the sewer lines and lift stations to be mod- eled will be collected from previous reports and the City' s maps . The inventory information will consist of -the manhole rim and invert elevations and the pipeline length, size, material, and street location. Drawings and related pump data for the 9 public lift stations will be reviewed to as- sess the available capacity. 5 . 2 - CONDUCT HYDRAULIC MODELING After the flow data and inventory data have been gathered, we will assess the available capacities in the sewer lines with the use of STATIC. Actual flow quantities , pipe capacity, and sizing calculations are based on Manning' s equation for uniform flow applied on a pipe-by-pipe basis . STATIC also calculates hydraulic Grade lines and distributes headloss back into the collection. system. Thus , surcharging is identified both by capacity limitations and backflow conditions . We will determine the present and available hydraulic capacity of the existing Atascadero sewer system. err' Once the sewer lines are identified and the model has been verified and calibrated during present flow conditions , the future design flow hydrographs developed in Task 4 , Develop Design Flows , will be routed through the collection system. Input sanitary and I/I flows will be allocated to each flow point load location on the basis of tributary area and land use. Wet weather flow will be evaluated for the design rainfall event. Various flow scenarios will be evaluated such as present dry weather, present wet weather, future dry weather, and future wet weather. Available capacity and the defi- ciencies will be noted for each scenario within the trunk sewer system and at the lift stations . STATIC will also be used to size new collector and trunk mains in the currently urserviced areas of Atascadero. The approximate line sizes and locations will be developed from design flows and available topographic data. New line ex- tensions to the remote lots will be compared with the option of providing a new lift station or line extensions in an adjacent basin. The hydraulic model (STATIC) will be provided to the City. This hydraulic model operates on IBM and IBM-compatible mi- crocomputers , is user friendly, and facilitates modification of data by City staff to determine impacts of future land use changes and development which may occur within a basin. Detailed information describing STATIC is provided in Task 8 , Provide Computer Hydraulic Model. TASK 6 - DEVELOP RECOMMENDED PLAN The preceding tasks are necessary to develop background data and design criteria for sewer system improvements in a master plan. The existing system deficiencies , under present and future scenarios during both dry and wet weather conditions, were identified in Task 5 , Determine System Capacity. For each sanitary drainage basin and future service area, alternative solutions to eliminate deficiencies and provide capacity needs under the future growth scenario will be iden- tified and developed. A cost estimate for each alternative plan will be prepared. The best apparent alternative will be selected based on this cost-effectiveness analysis . Once the best apparent alternative is selected, a staged construction program will be developed. The projects will be prioritized and staged according to projected development, complexity of the projects , and available funds. ~ t *#Av` A Capital Improvements Program (CIP) for each basin will be developed for staged construction.. The CIP will include preliminary cost estimates for the recommended improvements . The CIP will be staged from the final prioritization scheme selected by the City of Atascadero and CH2M HILL. The schedule for construction will list immediate projects nec- essary to correct possible existing deficiencies and those for the next 5 years and include stated expansion of the collection system beyond the existing configuration. TASK 7 - PREPARE PLAN MAPS The results of the master planning analysis will be presented to the City in a map format. These maps will be the basis for planning and scheduling the required existing capacity correction projects , future collection system extensions , and for future evaluations of the system capacity as devel- opment conditions change. The City has approximately 50 ae- rial maps available with contour information at 100 scale. These aerials cover the 3 , 600 acre ACSD/Urban Services Line service area. An overlay system has been used successfully on many proj- ects by CH2M HILL for these types of maps to indicate the system and associated information. Examples of our mapping abilities are provided in Appendix C. 7 . 1 PLOT EXISTING SEWER FACILITIES Using the City' s available as-built plans and the input data from the computer model , the existing collection system will be plotted onto an overlay to the aerial base maps . The overlay for the existing collection system will include the following information: o Street names o Assessment district boundaries o Properties with Cease and Desist for septic tank problems identified by the County o Manhole/cleanout location and number o Inver and rim elevations o Pipeline length, diameter, and material (if avail- able) c Public lift stations 0 Onsite private lift stations 7 . 2 PLOT CAPACITY IMPROVEMENTS Based on the results of Task 5 , Determine System Capacity; and Task 6, Develop Recommended Plan, the capacity cor- rection improvements will be plotted onto an overlay to the base map. These improvements will consist of a parallel or replacement pipeline to convey the peak flows to the treat- ment plant without surcharge or overflow. Alternative align- ments to avoid construction within developed areas will be presented when shown to be cost effective. Special con- struction considerations such as the Highway 101 and Atascadero Creek crossings will be shown. The information plotted on the map overlay will include up- stream and downstream manholes which designate the start and finish of construction,- new pipeline diameters , lengths, and the indication of whether the improvement is to be a replace- ment or parallel pipeline. 7 .3 - PLOT FUTURE COLLECTION SYSTEM EXTENSIONS During the future land use evaluation in Task 3 , new devel- opments will have been located. Using the results of Task 5 , Determine System Capacity, and Task 6 , Develop Recommended Plan, the required extensions to the collection system will be plotted onto an overlay to the base map. The pipeline data to be plotted will include manhole numbers and loca- tions , preliminary manhole rim and invert elevations , and pipeline length and diameter. The delineated basin boun- daries which represent individual service areas for these line extensions will also be plotted. TASK 8 - PROVIDE COMPUTER HYDRAULIC MODEL CH2M HILL will provide a static hydraulic model (STATIC) to the City which can be used to determine the capacity of the existing sanitary sewer system and plan future system ex- tensions . STATIC operates on IBM PC and IBM PC-compatible microcomputers . STATIC is user friendly and facilitates modification of data to determine impacts of future changes in land use and development. STATIC uses the same calculations as many mainframe dynamic models tc determine the capacity of the sewer lines , the hydraulic grade line, and surcharge conditions . Flowrates are specified at particular manholes and then routed through the system. Theoretical capacity, surcharge conditions , exceeded capacity, and current percent operating capacity with the specified flowrates are calculated with STATIC. w A e � t STATIC was developed by CH2M HILL as part of the Sewer In- formation and Maintenance Management System (SIMMS) computer software. SIMMS is a maintenance management program used to store the sewer system inventory, document and track mainte- nance activities , schedule routine maintenance, and generate statistical management type reports . STATIC can be operated independently or within SIM.MS. The steps to provide the City with the computer hydraulic model are: o Evaluate the City' s current computer system for use in running STATIC . Establish the hardware configuration to be used. o Establish the necessary data bases to run STATIC. o Provide a one-day training program and user ' s man- ual covering the use, maintenance , and updating of the system model. The current user manual which covers the use, maintenance and updating of the system model is provided with this proposal. CH2M HILL has experience in providing computer training, as reflected from experience with providing training on our SIMMS program. Additionally, we have successfully provided training for STATIC to other clients . SFP73/050 Exhibit B PAYMENT SCHEDULE The project has been divided into 8 tasks as detailed in Exhibit A, Responsibilities of Consultant. The lump sum fee by task to complete each task of the scope of work is provided in Table B-1 . These estimates include all labor and direct expenses to complete the work.

Box 747 Atascadero, CA 93423 Attn: City Manager Consultant: CH2M HILL 6425 Christie Avenue Suit 500 Emeryville , California 94608 at-tn • Robert Parent ACCEPTED AND AGREED this 22 day of MARCH 19 88 CITY: CONSULTANT: CITY OF ATASCADERO, a municipal corporation By BY BARBARA NORRIS Mayor Robert Parent ATTEST: BOYD SHARITZ C' 7Elerk APPROVED AS TO CONTENT: APPROVED AS TO FORM: Project oordinator �j�r,�ty Attorney PAUL SENSIBAUGH, Public Works Direct0 JGJ: fr/1/29/87 C:AGATA315 12 Exhibit A RESPONSIBILITIES OF CONSULTANT TASK 1 - IDENTIFY EXISTING CONDITIONS The first task in your project is to gather and review all existing information regarding the City' s sanitary sewer system and land use plan. We will work closely with City staff to collect information in one common format using ex- isting plans , reports , records , and discussions with opera- tion and maintenance personnel. 1 . 1 - PREPARE PROJECT METHODOLOGY Establishing the project methodology will be the first pri- ority of the project. The first step will be to meet with key City individuals in a workshop environment and discuss in detail the project objectives , determine the existing and future service area such as the ACSD or Urban Services Line and to what degree the City staff and others will be involved. During preparation of this proposal, we believe we understand what the City desires from the master plan design. During this workshop, CH2M HILL will work with the staff to develop an expansive decision tree. This decision tree will include the methodology of the master plan and will direct all future system evaluations . At the completion of the project, the City should then have the experience and capability to continue . 1 .2 - REVIEW EXISTING INFORMATION In this subtask, we will collect and review available infor- mation regarding the Atascadero sanitary collection system including, but not limited to, maps, records , surveys , plans , construction drawings , topographic information, rain- fall records , groundwater data, maintenance records , and water consumption data. Specifically, the following shall be collected and carefully reviewed: o City of Atascadero - Capacity Analysis and Eval- uation of the ACSD Wastewater Treatment and Col- lection System prepared by John L. Wallace and Associates . o City and County Genera'_ Plan documents . o As-built plan. 0 1" = 100 ' scale aerial mylars of the study area. o Assessment district boundary information. o Properties with septic tank problems defined by San Luis Obispo County for Cease and Desist. o Locations and drawing for the 9 public lift sta- tions and each on-site private lift station. TASK 2 - REVIEW WASTEWATER FLOW DATA The most difficult task in evaluating an existing sanitary sewer system is development of realistic wastewater flows during dry and peak wet weather conditions . We will collect and review the historical monthly flow charts from the treatment plant. The treatment plant historical charts should also include flow data during several rain events . This data will be used to assess historical infiltration/ inflow (I/I) levels within the City and to compare water consumption with wastewater flows. Rainfall records that correspond chronologically to the historical flow records will also be collected. This flow information will be used for calibration of the computer model, to quantify I/I components , verification of land use flow rates , and to develop peaking factor curves . Our extensive experience in flow monitoring work has given us many practical techniques to reduce the flow and rainfall data . We have a complete computer library to reduce the data into a manageable form in a cost-effective and timely manner. Since development of our software is complete, Atas- cadero can benefit from our extensive experience at minimum cost. 2 . 1 - DEVELOP RAINFALL-DEPENDENT INFILTRATION/INFLOW (RDI/I) HYDROGRAPH The first step in the analysis is to discern dry and wet weather flow conditions. The rainfall data collected during the monitoring period is used to accomplish this task. The next step in the analysis is to separate rainfall-dependent infiltration/inflow (RDI/I) from wet weather flow. RDI/I is the component of infiltration/inflow which enters the sani- tary collection system during and shortly after a rain event. The RDI/I component is the extra flow that causes the Atascadero flow to jump from 1 .0 mgd to 3 .6 mgd during peri- ods of rainfall . CH2M HILL has found that the quantity of RDI/I is highly dependent on antecedent soil conditions . As the soil be- comes saturated, more RDI/I can be expected. Although the presence of I/I is not considered to be substantial , the actual relative peak flow from each basin such as the older downtown areas may be significant. The capacity analysis of the trunk sewer system must be conducted during saturated soil conditions when RDI/I is at a maximum. In addition to soil conditions , the amount of RDI/I is also dependent on the intensity and duration of each rainfall event. CH2M HILL has developed custom software which is capable of synthetically simulating the amount of RDI/I for any given design event. The final product of this analysis will be the design storm RDI/I hydrographs for the system. Depending on the magni- tude of this flow, the City may wish to conduct further flow monitoring of key locations in the collection system. CH2M HILL has conducted many flow monitoring studies specifically with the objective of isolating areas within a collection system contributing significant I/I . A flow monitoring pro- gram of this type would supplement your ongoing internal closed-circuit television inspection program to identify actual sources of I/I such as broken pipe, open or broken joints, roots, laterals, direct connections , etc. 2 .2 - DEVELOP SANITARY FLOW ALLOCATION FACTORS Development has been categorized into three major land uses: o Residential o Commercial o Industrial CH2M HILL will review the sanitary flow allocation factors for each of these land uses specific to Atascadero. Res- idential and commercial categories will be further subdi- vided as detailed information is available. The industrial category is very minor within Atascadero. These unit flow values are not only category specific, but also season specific. 2 .3 - CALCULATE GROUNDWATER INFILTRATION The treatment plant flow recorded during the rainy season when GWI is present will be reviewed. Groundwater infiltra- tion rates will be calculated by subtracting calculated sanitary flow from non rainfall flow recorded during the winter season . GWI = DWF - SF Where: GWI = groundwater infiltration, mgd DWF = monitored dry weather (winter) flow, mgd SF = sanitary flow, mgd 3 .3 - PROJECT LAND USE Based on the updated general plan document, future land use will be identified. The identification of future conditions can only be an estimate because of the political nature of the general plan document. We will work closely with your planning staff as well as with San Luis Obispo County to identify the projected development. Development projections beyond even 2 years can only be determined within a range. These projections shall be summarized in a Technical Memoran- dum and reviewed with the City. 3 . 4 - CALCULATE SANITARY FLOWS The existing and future sanitary flows will be calculated based on existing and future land use data multiplied by the unit flow values from Subtask 2 .2 , Develop Sanitary Flow Allocation Factors. The future flows will be calculated based on projected land use for each development within the ACSD/Urban Services Line. The City' s current software and database (Lotus 123) will be utilized and expanded to include the future growth areas. TASK 4 - DEVELOP DESIGN FLOWS In this task, present and future design flows are developed for each predefined basin of the collection system. Design flows are the peak wastewater flow rates that are expected to be carried by system facilities after future development. These peak wastewater flows occur during wet weather peri- ods. During this master plan, design criteria shall be de- veloped to identify the following three components for peak wastewater flow: o Peak Groundwater Infiltration - The peak ground- water infiltration (GWI) rate for each basin will be derived in Task 2, Review Wastewater Flow Data. A GWI allowance will be applied to currently un- serviced areas and major extensions of the City' s sewer system. o Peak Sanitary Flow - Sanitary flows generally fol- low regular diurnal patterns, with peak flows oc- curring in the morning and early evening hours of the day. Peak hour sanitary flows will be esti- mated by applying a multiplier, called a peaking factor, to the ultimate development average sani- tary flow rates . The ultimate development average sanitary flow for each basin will be developed in Task 3 , Project Future Land Use. The peak hour sanitary flow will be calculated using the sani- tary flow peaking curve. o RDI/I Hydrograph - RDI/I hydrographs for each basin will be developed for a design rainfall event in Task 2, Review Wastewater Flow Data. An RDI/I allowance will be applied to currently unserviced areas and major extensions of the City' s collection system. Groundwater infiltration, peak sanitary flow, and rainfall- dependent infiltration/inflow will be combined to develop a design flow composite hydrograph for each sanitary basin and the future growth areas. The design flow hydrograph data for each basin will be used to analyze the existing collec- tion system, as described in Task 5 , Determine System Capacity. TASK 5 - DETERMINE SYSTEM CAPACITY The sewer capacity analysis will be performed with the use of computer modeling techniques . The hydraulic model STATIC, developed by CH2M HILL, will be used to predict and simulate flow in the wastewater collection system under various load- ing rates . 5 . 1 - INVENTORY MAJOR TRUNK SEWER SYSTEM An inventory of the sewer lines and lift stations to be mod- eled will be collected from previous reports and the City' s maps . The inventory information will consist of the manhole rim and invert elevations and the pipeline length, size, material, and street location. Drawings and related pump data for the 9 public lift stations will be reviewed to as- sess the available capacity. 5 . 2 - CONDUCT HYDRAULIC MODELING After the flow data and inventory data have been gathered, we will assess the available capacities in the sewer lines with the use of STATIC. Actual flow quantities , pipe capacity, and sizing calculations are based on Manning' s equation for uniform flow applied on a pipe-by-pipe basis . STATIC also calculates hydraulic grade lines and distributes headloss back into the collection. system. Thus, surcharging is identified both by capacity limitations and backflow conditions . We will determine the present and available hydraulic capacity of the existing Atascadero sewer system. Once the sewer lines are identified and the model has been verified and calibrated during present flow conditions, the future design flow hydrographs developed in Task 4 , Develop Design Flows, will be routed through the collection system. Input sanitary and I/I flows will be allocated to each flow point load location on the basis of tributary area and land use. Wet weather flow will be evaluated for the design rainfall event. Various flow scenarios will be evaluated such as present dry weather, present wet weather, future dry weather, and future wet weather. Available capacity and the defi- ciencies will be noted for each scenario within the trunk sewer system and at the lift stations . STATIC will also be used to size new collector and trunk mains in the currently unserviced areas of Atascadero. The approximate line sizes and locations will be developed from design flows and available topographic data. New line ex- tensions to the remote lots will be compared with the option of providing a new lift station or line extensions in an adjacent basin. The hydraulic model (STATIC) will be provided to the City. This hydraulic model operates on IBM and IBM-compatible mi- crocomputers , is user friendly, and facilitates modification of data by City staff to determine impacts of future land use changes and development which may occur within a basin. Detailed information describing STATIC is provided in Task 8 , Provide Computer Hydraulic Model. TASK 6 - DEVELOP RECOMMENDED PLAN The preceding tasks are necessary to develop background data and design criteria for sewer system improvements in a master plan. The existing system deficiencies , under present and future scenarios during both dry and wet weather conditions , were identified in Task 5 , Determine System Capacity. For each sanitary drainage basin and future service area, alternative solutions to eliminate deficiencies and provide capacity needs under the future growth scenario will be iden- tified and developed. A cost estimate for each alternative plan will be prepared. The best apparent alternative will be selected based on this cost-effectiveness analysis . Once the best apparent alternative is selected, a staged construction program will be developed. The projects will be prioritized and staged according to projected development, complexity of the projects, and available funds . A Capital Improvements Program (CIP) for each basin will be developed for staged construction. The CIP will include preliminary cost estimates for the recommended improvements . The CIP will be staged from the final prioritization scheme selected by the City of Atascadero and CH2M HILL. The schedule for construction will list immediate projects nec- essary to correct possible existing deficiencies and those for the next 5 years and include stated expansion of the collection system beyond the existing configuration. TASK 7 - PREPARE PLAN MAPS The results of the master planning analysis will be presented to the City in a map format. These maps will be the basis for planning and scheduling the required existing capacity correction projects, future collection system extensions , and for future evaluations of the system capacity as devel- opment conditions change. The City has approximately 50 ae- rial maps available with contour information at 100 scale. These aerials cover the 3 ,600 acre ACSD/Urban Services Line service area. An overlay system has been used successfully on many proj- ects by CH2M HILL for these types of maps to indicate the system and associated information. Examples of our mapping abilities are provided in Appendix C. 7 . 1 PLOT EXISTING SEWER FACILITIES Using the City' s available as-built plans and the input data from the computer model, the existing collection system will be plotted onto an overlay to the aerial base maps . The overlay for the existing collection system will include the following information: o Street names o Assessment district boundaries o Properties with Cease and Desist for septic tank problems identified by the County o Manhole/cleanout location and number o Invert and rim elevations o Pipeline length, diameter, and material (if avail- able) e Public lift stations 0 Onsite private lift stations VOW low 7 . 2 PLOT CAPACITY IMPROVEMENTS Based on the results of Task 5 , Determine System Capacity; and Task 6, Develop Recommended Plan, the capacity cor- rection improvements will be plotted onto an overlay to the base map. These improvements will consist of a parallel or replacement pipeline to convey the peak flows to the treat- ment plant without surcharge or overflow. Alternative align- ments to avoid construction within developed areas will be presented when shown to be cost effective. Special con- struction considerations such as the Highway 101 and Atascadero Creek crossings will be shown. The information plotted on the map overlay will include up- stream and downstream manholes which designate the start and finish of construction, new pipeline diameters , lengths , and the indication of whether the improvement is to be a replace- ment or parallel pipeline. 7 .3 - PLOT FUTURE COLLECTION SYSTEM EXTENSIONS During the future land use evaluation in Task 3 , new devel- opments will have been located. Using the results of Task 5 , Determine System Capacity, and Task 6 , Develop Recommended Plan, the required extensions to the collection system will be plotted onto an overlay to the base map. The pipeline data to be plotted will include manhole numbers and loca- tions , preliminary manhole rim and invert elevations , and pipeline length and diameter. The delineated basin boun- daries which represent individual service areas for these line extensions will also be plotted. TASK 8 - PROVIDE COMPUTER HYDRAULIC MODEL CH2M HILL will provide a static hydraulic model (STATIC) to the City which can be used to determine the capacity of the existing sanitary sewer system and plan future system ex- tensions . STATIC operates on IBM PC and IBM PC-compatible microcomputers . STATIC is user friendly and facilitates modification of data to determine impacts of future changes in land use and development. STATIC uses the same calculations as many mainframe dynamic models to determine the capacity of the sewer lines, the hydraulic grade line, and surcharge conditions . Flowrates are specified at particular manholes and then routed through the system. Theoretical capacity, surcharge conditions, exceeded capacity, and current percent operating capacity with the specified flowrates are calculated with STATIC. STATIC was developed by CH2M HILL as part of the Sewer In- formation and Maintenance Management System (SIMMS) computer software. SIMMS is a maintenance management program used to store the sewer system inventory, document and track mainte- nance activities, schedule routine maintenance, and generate statistical management type reports . STATIC can be operated independently or within SIMMS. The steps to provide the City with the computer hydraulic model are: o Evaluate the City' s current computer system for use in running STATIC. Establish the hardware configuration to be used. o Establish the necessary data bases to run STATIC. o Provide a one-day training program and user' s man- ual covering the use, maintenance , and updating of the system model. The current user manual which covers the use, maintenance and updating of the system model is provided with this proposal. CH2M HILL has experience in providing computer training, as reflected from experience with providing training on our SIMMS program. Additionally, we have successfully provided training for STATIC to other clients. SFP73/050 Exhibit B PAYMENT SCHEDULE The project has been divided into 8 tasks as detailed in Exhibit A, Responsibilities of Consultant. The lump sum fee by task to complete each task of the scope of work is provided in Table B-1 . These estimates include all labor and direct expenses to complete the work. CH2M HILL' s total lump sum fee to complete the master plan and prepare maps for your wastewater collection system is $24 , 900 . Specific items included within this estimate are noted below for reference: o Flow Data Analysis--Sufficient flaw data must be collected from the wastewater treatment plant. The resulting flows will be critical for evalua- tion of the sewer system. o Future Land Use--CH2M HILL has a planner experi- enced with future growth projections. o Computer Modeling--Review of the City' s collection system maps will provide the basis of hydraulic analysis of the trunk sewer system. o City Involvement--We have developed our approach to your project to include your staff. This estimate is representative of a flexible program. As the program progresses , the approach can be adapted to meet the critical needs as they are identified by your staff or the CH2M HILL team.
